Abstract: Objective To explore the influence of high fluoride exposure on reproductive hormones in male living in endemic fluorosis villages in China. Methods A cross sectional study was conducted in Tongxu county in Henan Province, China. Endemic fluorosis villages and control villages were selected by random sampling according to fluoride concentration in drinking water and the prevalence of endemic fluorosis. Local male residents aged from 18 to 50 years old who were born and grew up in the investigated villages were recruited as subjects by cluster sampling. Fasting blood and urine samples were collected. The serum level of GnRH was detected using ELISA. The serum level of LH, FSH, E2, and T were determined by chemiluminesence immunoassay (CLIA). Results The serum levels of FSH were 7.82 mlU/ml, 10.20 mIU/ml and 9.57 mIU/ml in male from defluoridation villages (DFPG), high fluoride villages (HFG) and control villages (CG) respectively. FSH level in male from DFPG was significant lower than that from HFG and CG (P<0.05). The serum levels of E2 were 33.67 ng/mL, 29.17 ng/mL and 28.99 ng/mL in DPFG, HFG and CG respectively. E2 level in male from DFPG was significant higher than that from HFG and CG (P<0.05). Serum levels of E2 in CG were associated with LH (r=0.343, P=0.000), age (r=0.195, P=0.015), and inversely associated with serum FSH (r=-0.237, P=0.003), whereas this correlation was not observed for serum E2 level in DFPG and HFG. Conclusion Long-term fluoride exposure in drinking water may influence the reproductive hormones in males living in endemic fluorosis villages.

Abstract: In this research, Amir kabir and mirza koochak khan’s agro-industry in west side of karoon river were considered and original drain of each unit was selected and at three station, beginning of the drain (first station), middle of the  drain (second station) and end of the drain (third station), nine selected units parameters including (oxygen solution, temperature, Ph, BOD5 COD, phosphate nitrate, Ec, Tarbidity) were measured. For a year, above reviews were performed in each season at three station of original drain of both units agro-ingustry. Then by using customary methods, a qualitative index of Sewage was measured at three stations of each unit’s drain for every season. Finally annual qualitative index was measured for sewage of each unit. After statistic analysis of results, It is observed that: we had been faced to reduction of sewage’s qualitative index along with original drains of both units of agro- industry from first station towards second station and finally third station. It means that. in all seasons in both drains, the quality of ending drain of sewage was always lower than that in beginning of drain. Also during the different seasons of year, meaningful changes were observed in sewage quality of original drainages of both  units. Sewage qualitative index was reduced in both units during autumn and winter.  In research, it was observed that this fact can be because of not only the sometime cultivation season of sugar can’s cuttings and start of harvesting in different farms but because of operation including fertilizing and spraying, in another word with starting the season harvesting of cane’s production farms of sugar cane also are starting to act, so the sewage of mentioned units directly is shed to original drain. All of these factors cause a full of sewage’s qualitative index in meaningful limit during autumn and winter forwards spring and summer. In this research , correlation coefficients between sewage’s qualitative index and each one of chemical physical nine units parameters were measure and based on those coefficients, simple Regresion equations between sewage’s qualitative index and each factors were written, also multilateral Regresion relation between sewage’s qualitative index and all factors were presented.

ABSTRACT: Background: Prostate cancer is a major health problem throughout the developed world. Immunohistochemistry plays a very important role in the diagnosis of minimal prostatic adenocarcinoma and to exclude one of its benign mimickers, but it should always be interpreted in the context of the H&E appearances. In some cases of minimal prostate cancer morphologic features do not allow a diagnosis of carcinoma. In such situation, the presence of AMACR and the absence of basal cell marker (p63) confirm the presence of prostate cancer. In addition, Ki-67 a proliferating marker have a strong relationship with Gleason's grading, which has an important relationship with the prognosis of prostate cancer. The aim: Assessing the usefulness of immunohistochemical analysis with Alpha-methylacyl-CoA racemase (AMACR) and p63 to confirm the diagnosis of minimal prostate cancer. Also, detection of the prognostic role of ki67 in minimal prostate cancer detection and its association with p63 expression in prostate cancer. Methods: 50 needle biopsy specimens, including 30 with small foci of prostatic adenocarcinoma and 20 benign prostate (≤ 1mm or <5% of needle core tissue) were stained immunohistochemically with AMACR, P63 and Ki67 antibodies. Results: Of 30 cases of small foci of prostatic adenocarcinoma, 27 (90%) expressed AMACR; all malignant glands were negative for basal cell staining p63 (nuclear stain). All benign glands were recognized easily by basal cell marker (p63) positivity. There was focal positive staining with AMACR in 2 benign cases showing atrophy. A statistical significant correlation was observed between ki67 expression and increased Gleason's grade (p=0.02). Cytoplasmic expression of p63 was high in high grade prostate cancer, and it was associated with higher frequency of ki67 positive cells in prostatic adenocarcinoma. Conclusions: Immunostaining with the p504s and p63 could improve the diagnostic performance and helped in avoid carrying out new biopsies in small foci of prostatic carcinoma detection. An important relationship with the prognosis of prostate cancer was noticed through the strong relationship of Ki-67 marker with Gleason's grading. Therefore, we propose that this marker can be applied along with other prostate cancer prognostic factors.

Abstract: TRAIL as a member of TNF ligands is involved in the anti-tumor mechanisms by its cytotoxic activity inducing apoptosis, and has been explored as a tumor target reagent in the therapy of different tumors. In acute promyelocytic leukemia (APL), TRAIL was used to be token as a crucial molecule that was up-regulated by retinoic acid and induced the blast cell to differentiation and apoptosis. However, our findings indicated that AP1060 cell, an APL cell line, produced a high level of TRAIL, and its growth and proliferation depended on the auto-secreted TRAIL. Furthermore, the above phenomenon may be related to the TRAIL-mediated NF-kB activation. It suggests that there may be a new therapy approach to the subtype of APL.

Abstract: There are various studies done on relationship between emotional intelligence and leadership, only a few of them were took part in educational organizations by focusing on view point of the Bass & Avolio’s leadership styles and Bar-On’s theory of emotional intelligence. This research made an attempt to prepare an empirical research-evidence for supporting the proposed link between school principal’s emotional intelligence and leadership styles. Collected data (n=268) were analyzed by using. The Pearson’s correlation coefficient. The result indicated statistically significant relationship between principal’s emotional intelligence and leadership styles. This significant relationship resulted that the higher level of the principal's emotional intelligence is linked to the transformational leadership style. In contrast, transactional and laissiez-fair leadership styles were not positive associated with emotional intelligence. Consequently, school programmer should be focused on the especial training methods to enhance principal's emotional intelligence level whereby they can develop the transformational leadership style qualities. These development qualities concerns about transforming the present condition and followers requirements.

Abstract: The study was carried out in Benue State of Nigeria by the use of questionnaires administered to 200 women farmers in HIV prevalent and non prevalent areas. Frequencies and percentages were used to explain descriptive data while t-test was used to analyse the inferential statistics. The awareness and knowledge of HIV among women farmers was average, and there was no behavioural change towards sex as almost all respondents shy away from the use of condoms. There is significant difference in farm size in the prevalent areas (t = 2.982 P < 0.05) as compared to non prevalent areas. The non-prevalent areas had a higher mean score than the prevalent areas. The results obtained from the study showed that there was a general decrease of agricultural productivity in HIV prevalent areas than non-prevalent areas. In conclusion, the two study areas, which represent the prevalent and non-prevalent areas, HIV was established to be high in both transmission and prevalence. Over 70% of the respondents are sexually active, the study indicates that the rate of promiscuity is high and among the respondents as unmarried residents has had at least 3 sexual partners. The knowledge and use of condoms is low. Only 7% and 6% of respondents in non-prevalent and prevalent areas have used condoms. The epidemic has severely affected and worsens the economic situation within the respondents, and has therefore placed demands on women who are both agricultural workers and caretakers.

Abstract: Today, fish farming and breeding is considered as one of the most significant sources of protein supply in the world so that we can observe the remarkable improvements in this field. Artificial methods of fish breeding began in China and dates back to 3000 years ago. However, though the precedence of breeding fish in a pool is long, the artificial reproduction is a new experience. The first step in artificial fertilization was taken by a German scientist named Ludwick Jacobi. Despite the long experience of fish farming in the world, in Iran, it has been started in 1972 by reproducing Acipenseridae and in 1959 by reproducing rainbow trout. Industrial and economical growth as well as the need for supplying food for the growing population and the higher quality of fish protein compared to that of other kinds of meat has caused an increasing interest in the fish and fishing in the seas and water resources and has made it an important source of attracting foreign currency. Iran should also take the same actions considering the current policies. Therefore, reproduction of cold water fish should be taken into consideration as one of the most significant issues in this regard and all kinds of facilities should be provided for its optimal application[3].  There is a high potential in national waters of Iran in this regard few of which are currently being used. One reason for this is the lack of technical knowledge and required experience in fish farms management. Most farmers who engage in this occupation have suffered losses or have not used the available facilities properly due to the lack of sufficient technical and scientific knowledge. Regarding the above-mentioned issues, this study aims to signify the effective factors in the production of cold water fish farms and prioritize them based on decision making methods of AHP[4].

Abstract: Optical burst switching (OBS) has been introduced as a short term implementable solution for future all-optical networks. Its performance evaluation received a considerable attention and does not seem to be weaken. In prevalent studies, an OBS network is strictly divided into edge and core domains, while practically for future all-optical mesh network deployments; this is not valid for most of nodes. In these networks, not only a few but probably majority of the nodes will have to combine both functionalities to provide flexible operation. Such nodes are termed herein joint edge-core OBS nodes. In this paper, an architecture of a joint edge-core OBS node is studied and  a new scheduling algorithm have been proposed to multiplex the local assembled traffic along with the transit traffic. Thorough simulations have been done on benchmark networks to show the significance of edge scheduling in joint edge-core OBS nodes.

Abstract: Scheduling systems are an integral part of edge nodes in modern communication systems. These nodes aggregate the incoming traffic flows and groomed traffic is sent to core network. The aggregation is done on the basis of scheduling criteria. In this work, we have analyzed a scheduling system where high priority traffic is exhaustively served. The modelling approach we have used is Markov chain modelling. It is assumed that buffers available are of finite nature. Important performance measures such as blocking and waiting probabilities and mean flow time have been analyzed to give an insight into the system behavior. To prove the accuracy of analytical modelling, all results have been simulated.

Abstract: This study was carried out to evaluate the effects of replacing alfalfa hay with ensiled mixed tomato and apple pomace (EMTAP) on ruminal fermentation and apparent digestibility of diets. Six multiparous Holstein dairy cows in mid lactation were used in 3×3 Latin square design and fed alfalfa hay plus concentrate mixture with three levels replacement with EMTAP (0, 15, 30%) during 63 days. Results showed that, differences between treatments were significant. Feeding EMTAP resulted in a significant higher acetic and propionic acids and total volatile fatty acids concentration and significant (P<0.01) lower rumen pH. The substitution of EMTAP in dairy cow diets is associated with a better DM, OM, CP and NDF digestibility. It was concluded that, EMTAP can efficiently replace up to 30% alfalfa hay. The nutritive value of tomato and apple pomace could be improved when they are used together (50:50) in dairy cows diet.

Abstract: Considering the fact that children are among the most vulnerable communities and since they can’t overcome adversity due to their young age and intellectual and physical immaturity, placing priority on their basic and natural rights is something obvious and is the natural and legal authorities’ responsibility. Since all human beings are subject to the rights and freedoms enshrined in the constitution without considering their race, color, gender, language, religion, and so on, children must have particular rights because they make the country’s future so that their welfare, liberty, happiness, and beliefs must be formally recognized and necessary facilities and equipments must be properly and healthily provided for their physical, mental, ethical and social growth in a healthy free environment. Children need adequate family and social security and special support including certain care before and after birth. Even children who are intellectually and physically disabled need special care and attention together with proper training appropriate to their disability status.

Abstract Testing plays an important role in any project irrespective of the domain. The ability to test right before it reaches the intended customer matters. Test effectiveness is an important metric that tracks the ability of the testing team. The efficiency of a tester to cover all aspects of testing and ensuring 100% coverage determines the quality of the product. There could be number of factors that influence the test effectiveness. Organizations rely on the quality assurance team to strategize and plan the testing phase. Past experience in handling similar testing projects matter. Shifting left, the opportunity to be in pro-active mode helps to improve the efficiency. Predictive process performance models can be built for test effectiveness. This paper illustrates the process performance model to predict test effectiveness based on data from life science project in an organization.

Abstract: Objective To explore the effect of breviscapine on expression of IL-6 and ICAM-1 in rat with acute lung injury induced by left heart ischemic reperfusionand the mechanism of breviscapine protecting respiratory function. Methods 60 rats were divided into 2 equal groups randomly: group 1 is treatment group (TG), group 2 is control group(CG).All rats were made left heart ischemia-reperfusion model by ligaturing the anterior descending branch 30min and loosing. Rats in this group were intravenous injected breviscapine (10mg·kg-1) when the myocardial ischemia had been for 10 minutes. Whilethe rats of CG were treated with normal saline.The same amount of rats in 2 groups were killed at 3 point in time: 30min after ligaturing (T1), 30min after loosing(T2) and 60min after loosing (T3).All rats were recorded and observed respiration curve with BL-420 biological signal collect and analysis system, measured the expression of interleukin 6 (IL-6)and inflammatory cell adhesion molecules-1 (ICAM-1) with Immunohistochemistry, measured the expression of IL-6 in peripheral blood and bronchial alveolarlavage fluid with Enzyme Linked Immunosorbent Assay methods, and measured the activity of myeloperoxidase (MPO) in lung tissue with colorimetry. Results In T1, T2 and T3,the level of the expression of IL-6 and ICAM-1 in CG were higher than those in TG, the activity of myeloperoxidase in lung tissue of CG was stronger than that of TG, the expressions of IL-6 of CG were higher than those of TG in peripheral blood and bronchial alveolarlavage fluid, and the amplitude and duration time of respiration curve of TG was higher than those of CG. The comparison were great. Conclusions Breviscapine can inhibit the expression of ICAM-1, which means that leukocyte adhesiveness/aggregation and release reaction of can be reduced in the pulmonary circulation, the expression of IL-6 can be decreased, and inflammatory cascade response will be reduced to protect respiratory function.

Abstract: Periodontitis is a multifactorial inflammatory disease characterized by destruction of tooth supporting tissues. Environmental, genetic and   immune factors are involved in progress of the disease. Recently numerous studies have focused on the role of different cytokines in development of periodontitis.The aim of the present study was to estimate the serum level of IL-8, IL-12 and IL-33 in patients withchronic periodontitis, generalized aggressive periodontitis (GAP) and healthy individuals.A total of 96 subjects were included in the study of which 35 patients had chronic periodontitis, 26 patients had generalized aggressive periodontitis and 35 persons was healthy group. 3ml blood obtained from each person and serum samples separated. Level of IL-8, IL-12(p70) and IL-33 were determined by enzyme linked immunosorbent assay.Data analyzed with Kruskal-Wallis, Mann-Whitney testand SPSS Ver.16 software.The level of IL-12 increased significantly in chronic and aggressive patients than in health group (p=0.001). On the other hand, there was no significant difference at IL8 dose level between periodontitis patients and healthy group (p>0.05). The amount of IL-33 was no difference between patients and healthy group (p>0.05).There was a significant association between the level of IL-12 with chronic periodontitis and GAP.

Abstract:Land degradation in the Niger Delta region of Nigeria has been aggravated by deforestation with resultant losses of vital biodiversity. In this paper, we provided an assessment of land degradation with drivers of deforestation in selected states in the Niger Delta. Data were collected with multi-stage sampling procedure and analyzed using descriptive and Tobit regression methods. Results show that average age of the farmers is 51.55 years with average years of education being 8 years. The farmers recognized a degraded land through the colour (20.79%), depth of the soil (4.4%) and performance of maize crop (71.73%). Deforestation is positively influenced by sex of the household heads, market distance, population per forest land, purchased land, sold land, fertile land and population density. Legislations for curtailing the pace of deforestation should be enforced with some hints on population control.

Abstract:The study seeks to determine the factors that influence public health care seeking behaviour based on the poverty status of households in rural areas. The primary data were collected with well-structured questionnaire while the secondary data were obtained from the local government health records. Descriptive analytical methods, benefit incidence analysis and Multinomial logit regression were employed for data analysis.  The results show that average spending on health by households is N456.40, while the health subsidy accruing to household from government is N687.98. Benefit incidence analysis shows majority of government spending accrue to the poorest segment of the population. Also, the factors that significantly influence (p<0.05) households patronage of private clinics are years of education, presence of hygiene facilities and registration cost. Furthermore, age of household head, family size, presence of hygiene facilities, communication access (GSM), drug and registration cost will make household patronise chemist. Years of education of household head, registration cost and hygiene facilities will make household patronise self-care. Adequate education to alert households of the risks involved in inadequate decision regarding health problems and adequate funding of government hospitals were recommended, among others.

Abstract:Result of studies conducted and predictions made by World Bank and other international organizations indicate that two third of world population will live in the urban areas in the third millennium. Urban living in Iran has experienced a rapid growth during past 4 decades.  Increased numbers of cities, wide spread migration from rural areas, and higher birth rate have significantly increased urban population.  Higher disposable income and reduced work hours have improved social welfare.  These changes have produced complicated and encompassing consequences in urban areas at national and local levels, including air and environmental pollution, densely populated urban areas, plus difficulties and inequalities in city and social services. Providing for social needs of various age groups in such circumstances and under heavy influence from world developments require extensive planning.  A part of this planning includes provision of additional public recreational spaces.  The complicated nature of urban living demands special focus on projects which may contribute to social welfare by increasing the available public areas including recreational parks. One such project is Hezar O Yek Shahr Recreational, Sports, and Cultural Complex in District 22 of Tehran Municipality.  This project is being implementing on a 150 hectare divided into seven zones assigned for recreation, tourism, sports, education, cultural activities, and public services.  This project is one of a kind in Iran and Middle East. Hezar O Yek Shahr project is already under development at a total estimated cost of about $2 billion.  As an indication of the size of this undertaking, this project will require 993,000 cubic meters of earth removal and 404,000 cubic meters of filling.  This complex will have various subdivisions for hotels, shopping centers, recreation area, water-park, and amusement center.  The amusement park alone will have 83 attractions.  It is estimated that 141961 visitors will visit this complex per day. Article 50 of Iran Civil Laws and article 172 of The 5th Iran National Development Plan require environmental impact assessment of any project to be undertaken by any large production, industrial, service, and infrastructural unit.  In compliance with the legal requirements, the environmental impact of this large and significant project was assessment in this study by using Pastakia Matrix. This study examined the impact of 18 civil and infrastructural activities on environmental parameters in two phases of project construction and operations. The results of this study showed that the project implementation option had higher number of positive impacts.  Consequently, the implementation of this project is preferable over non-implementation option.  However, project implementation is supported as the final decision subject to implementation of certain management measurements.

Abstract: Background: Epilepsy is an abnormal functional state of the central nervous system that is characterized by uncontrolled nerve cell activity and clinicaly by convulsive seizure with or without loss of consciousness. Valproic acid is widely used antiepileptic medication and has sever toxic effect on liver , this study aimed to investigate the histopathological and histochemical changes due to the effects of therapeutic dose ( 25mg/kg b.w.) of antiepileptic drug (Valproic acid) in albino mice. Material and methods: Forty mice were used, they were divided into four groups, one group serves as control group and the other three groups (A, B and C) administered the drug as follow: Group A received Valproic acid for 15 days, group B received Valproic acid for 30 days and group C, the recovery group (animals were administrated with drugs for 30 days then administration was stopped for another 10 days). The animals were sectioned 24 hours after the last dose, liver was taken for histopathological and histochemical studies. Results: The drug induces toxic effects on liver tissue which showed vacuolar degenerative changes, hypertrophied nucleus with fragmented chromatine, inflammatory cells aggregates and congested vasculature.Conclusion: Valproic acid has sever toxic effects on liver tissue and the toxicity was time related. Sort of recovery was recorded after discontinuation of the drug so its effect was reversible.

Abstract: In this paper the development of a hybrid intelligent information system for the administration of massive Hajjis crow has been described. The main objective is to design an information system to manage the crowd during one of Hajj rituals, "Nafra" so as to avoid crowding disasters. The developed system incorporates data acquisition and processing via several thermal cameras deployed as sensors at strategic points on “Nafra” access roads. The sensors are linked to an analysis module, which in turn measures crowd flow and density in real time. The analysis results are fed into a fuzzy logic module to determine the priority of roads with respect to their widths and lengths. Then, the integrated decision support system generates decisions to the controllers in order for them to take the appropriate actions. Hybridization is done by integrating fuzzy logic, operations research and decision support to produce alternate decisions to the system controllers enable them to control the movement of the huge crowd. The paper illustrates different system components. It also describes the architecture of each component as well as the architecture of the entire system.
A complete case study is illustrated with real snap shots of system screens in order to prove the system methodology. The results show solid decisions that help the authorities manage the huge pilgrim crowds. The system can contribute to provide complete safety for crowds during the “Nafra” event that attracts millions each year.

Abstract: This   study was carried on 61 calves from different farms at Sharkia governorate. From these calves 25(healthy control calves) and 36 diarrheic dehydrated calves were used for this study. The calves had normal body temperature. The clinical signs of the diseased calves included a whitisg to yellowish diarrhea with foetid odour and highly moisture percent of faeces. Moderate and severe dehydration were recorded including varying degree of dryness of skin, sunked eyes, recumbency, sometimes coma and death occurred. 18 calves showed hyperpnea with standing position but need help to stand (moderate degree of dehydration and clinical acidosis). Other 18 calves showed lrecombency, a decrease of heart beats and respiratory rates (severe degree of dehydration and clinical acidosis). Blood analysis of diseased calves showed acidemia as well as a significant increase in erythrocytic count, haemoglobin content and packed cell volume with a non significant variation in Leucocytic count. Serum analysis showed an increase of the total protein, total solids, a significant increase of serum urea nitrogen and creatinine as well as hyponatremia, hypocholoremia and hyperkalamia. Thereapeutic trials: Antidiarrheal drugs as well as isotonic solution in moderate dehydration and hypertonic together with isotonic in severe dehydration were used for treatment. It could be concluded that diarrhea and dehydration in calves has a harmful effect on general health condition, gastrointestinal tract, body fluid, blood, serum and faecal contents. Hypertonic together with isotonic solution and antidiarrheic drugs safe the animal life and control this problem.

Abstract: Protozoan Toxoplasma gondi is an important cause of serious infections spreading among the human population and domestic animals in the world and the chronic phase in animals is after asymptomaticsyndromes. What's disease, acute infection, asymptomatic? In allcases of acute infection due to the persistence of parasite cysts observed, the disease is caused by the reactivation of cysts. Married women exposed to the disease could predispose them to disease, This study aimed at determining the level of IgG antibodies at the time of their marriage counseling has been done in Zahedan. During this descriptive – analytical study, 280 women referring to the Razmjoo moghaddam central laboratory of Zahedan from February 2009- to December 2009 were measured for IgG by ELISA method. Then blood samples were taken from them and the level of blood IgG antibody was measured by ELISA method and the results with obtained IgM measurement and their relationship with demographic issues, including those of residence, education level, were noted. Home cat care and pet at home, and how the meat is cooked were surveyed.28.2% of patients with type IgG antibodies were having significant positive correlation with the maintenance of home cats and how the meat was cooked. In other words, women who kept cats in their home and had half-cooked or raw meat to eat, showed increased positive antibody. The results of these studies indicated that a high percentage of susceptible women of childbearing in Zahedan city, were without a note of antibodies against Toxoplasma and thus they are susceptible to infection. Thus in order to prevent infection of susceptible pregnant women and prevent problems that may arise during pregnancy, awareness and control of pathogens associated with disease, education and health care practice, are recommended.

Abstract: Philidalphia(Ph) chromosome [t(9;22)(q34;q11)] which results in the production of BCR-ABL fusion protein, with deregulated tyrosine kinase activity, is a hallmark of chronic myelod leukemia(CML)  and present in a high risk group of acute lymphoblastic leukemia(ALL). This BCR-ABL tyrosine kinase has been specifically targeted by tyrosine kinase inhibitors (TKI) which have profoundly modified the treatment and prognosis of the diseases harboring this genetic abnormality. Consequently, the rapid and accurate detection of BCR-ABL is of utmost importance in the diagnosis and optimal management of leukemias. Currently applied techniques are RT-PCR and cytogenetic analysis, which are costly, time-consuming, and require specialized laboratories. We utilized a recently developed immunoassay that qualitatively identifies the presence of BCR-ABL proteins in the leukemic cell lysate. The BCR-ABL is captured and detected by a cytobead assay and analysed by flow cytometry. We aimed at evaluating the effectiveness of this technique in detecting BCR-ABL in ALL patients and identifying CML cases among CML-suspected patients. The assay was conducted on 100 peripheral blood and bone marrow samples of 20 healthy controls, 55 patients suspected of having CML and 25 ALL patients. Results were compared to those obtained by conventional karyotyping and flouresence in situ hybridization (FISH). BCR-ABL protein was positive in 35/55(63.6%) of CML suspected cases and 15/25(60%) ALL cases with 100% concordance with cytogenetic analysis data. The procedure was simple and feasible and proved to be reliabe in rapidly idenyifying CML cases and Ph+ALL allowing for their prompt management.

Abstract: The purpose of this investigation was to examine the demographic variables of length of teaching experience and age, affects self esteem, job satisfaction and organizational commitment of faculty members of educational colleges in Mysore (India). In addition, the study aimed to find out the relationship between the three variables i.e. self esteem, job satisfaction and organizational commitment of faculty members of educational colleges in Mysore. This research has been designed with a descriptive model. The study was carried out on all the faculty members who are working in educational colleges, affiliated to the University of Mysore in Mysore. The sample for the present study was drawn using stratified random sampling technique. About 165 survey questionnaires were distributed in 2012.Multiple follow ups yielded 134 statistically usable questionnaires. For collecting data, three standard measures of Rosenberg self esteem scale (1965), a job satisfaction scale developed by Singh and Sharma (1999) and organizational commitment questionnaire (OCQ) developed by Mowday, Steers, and Porter (1979) were used to confirming the research hypotheses; and for analyzing the obtained data, the statistical methods of one way ANOVA, Pearson's Correlation Coefficient and DMRT (Duncan’s Multiple Range Test). The findings of the study indicated a significant difference between length of teaching experience and age of faculty members with reference to their self esteem. But with regard to job satisfaction and organizational commitment there was no significant differences. Test statistics revealed that teacher’s self esteem, job satisfaction and organizational commitment were mutually related. Based on the results of this study, self esteem was found to be negatively related to job satisfaction and organizational commitment. These findings are important since previous research has not tested these variables together.

Abstract: Background: Administration of the glycoprotein IIb/IIIa inhibitors, including eptifibatide is an effective adjunctive treatment strategy during primary percutaneous coronary intervention (PPCI) for ST-segment elevation myocardial infarction. Recent data suggest that the intracoronary administration of these drugs during PPCI may increase the efficacy of them. Methods: A total of 40 ST-segment elevation myocardial infarction patients undergoing PPCI within 12 hours of symptom onset were randomized to either intracoronary or intravenous two boluses of eptifibatide (0.180 µg/kg) each 10 minutes. The primary endpoints of the trial were enzymatic infarct size, myocardial reperfusion measured as ST-segment resolution (STR), and post-procedural Thrombolysis in Myocardial Infarction (TIMI) grade flow of infarct related artery. The secondary endpoints were intra-procedural adverse effect (arrhythmia) and no-reflow phenomenon, in-hospital mortality, reinfarction , hemorrhage and post-procedural global systolic function. Results: Post-procedural TIMI grade 3 flow was achieved in 95% and 90% of the intracoronary (IC) and intravenous (IV) groups (P=0.61). The enzymatic infarct size assessed by the area under the curve of creatine phosphokinase-mb (CPK-mb) in the first 48 hours after PPCI  (µmol.L-1.h-1)  was similar in the IC and IV groups with 7206 (IQR, 5346.75 to 10384.50) versus 7294 (IQR , 10384.50 to 10384.50), P=0.87. Complete STR was achieved in 55% and 40% of the IC and IV groups (P=0.27). No deaths, urgent revascularizations, reinfarctions, or TIMI major bleeding events were observed among the both groups. Conclusion: Although, the IC administration of eptifibatide is safe, but does not add a benefit in comparison to the standard IV route.

In order to examine the effect of spraying plant growth inducers on performance and performance components of corn in the double-cross 704 corn, a test in the form of a randomized complete block design under condition of a farm with eight replications and six treatments of plant growth inducers, Marmarine, HB_101, auxin, cycocel, ethephon and control was performed. Analysis of variance of data showed that characteristics of the number of rows of grain, number of grains per row, number of grains per maize, grain weight per maize, weight of 1000 grains, cob weight, grain performance and harvest index were significant at the 5% level. The Marmaryn , HB-101 and auxin treatment led to increase in the number of rows of grain, number of grains per row, number of grains per maize, grain weight per maize, weight of 1000 grains, cob weight, grain performance and harvest index. So that the greatest value was related to Marmarine treatment, then HB_101 treatment and eventually auxin treatment. Also, Cycocel did not indicate any significant effect on the performance and performance components of corn except for reducing the weight of 1000 grains. Ethephon decreased grain number per row, number of grains per maize, weight of 1000 grains and cob weight, but its impact on the performance was not statistically significant.

Abstract: Introduction: Multiple sclerosis (M.S) is one of the most common chronic diseases of the central nervous system. The chronic nature of the disease, lack of prognosis, lack of any definitive cure and affecting the individual in the young age will cause several mental disorders in patients, including depression and low rate of happiness. Objective: Evaluation the effect of aquatic exercise programs on depression and happiness levels of the patients with multiple sclerosis (M.S). Methodology: In this quasi-experimental research, 40 patients with M.S. with grades 1 to 4 were randomly divided into two experimental and control groups. The exercise program was performed for the experimental group for eight weeks, three sessions per week with 50-60 percent of the maximum heart rate. The depression and happiness rates were evaluated using the Beck Depression questionnaire and the Oxford Happiness questionnaire at intervals before and after the exercise. Analysis of the data was performed by independent t test, and the data normalization was evaluated using the Kolmogorov-Smirnov test. Results: The test group, regarding the depression level (p < 0.001) and happiness level (p < 0.002) after exercise had significant changes compared to the pre-exercise time. Thus, the mean differences for depressions and happiness levels of these two groups were obtained respectively as 4.65 and -7.80. Conclusion: Regular aquatic exercise provides more productive emotional communications and also causes the improvement of depression and increased happiness in M.S. patients. Hence, doing these exercises is recommended as an effective non-pharmacologic therapy method in addition to drug therapy.

Abstract: In the present study, the behavior of the different isotopes activity concentrations for three different rock samples (siltstone, shale and sandy dolomite) as well as in the different leachates of these rocks were studied at different time intervals, using a HP-Ge spectrometer. The activity concentration of 238U for the leachates gradually increases while that for 235U is nearly constant. The results revealed that the solubility gradually decrease from 235U to 234U, 238U and 226Ra respectively. The reason for the higher 234U concentrations in leachates is due to α- recoil process which enhances the mobilization and solubility of the decay product of 234U relative to the parent (238U).Also the238U activity concentration percent in leachates to that in origin samples increases towards equilibrium state due to the growth of the 234Th. It is noticed that the238U% of siltstone and shale are very close and higher compared to dolomite which is much less in spite of the higher activity of the dolomite rock sample. The ratio (234U/238U) for the first measurement of the leachates was considered at zero time as 1.09±0.17, 1.4±0.21 and 1.6±0.18 for siltstone, shale and sandy dolomite respectively. The enrichment of 234U is accordingly related to the crystal damage and leaching, which are the main mechanisms for the (234U/238U) disequilibrium. The variations in the activity ratio ((238U/235U ) are related to the increase in the activity concentration of 238U with time and also to very little variations in 235U.The solubility for Ra, Th, and K are very low and mainly remain in the residuals.

Abstract: Background: Helicobacter pylori are well recognized as a major cause of gastrointestinal illnesses and gastric cancers. Therefore, the current study aimed to assess different methods for detection of H. pylori in the oral cavity (saliva and dental plaque) and in gastric biopsy among patients with gastric affection, as well as, detection of H. pylori antigen in stool. Moreover, to evaluated the antibiotic susceptibility testing of the isolated strains.  Methods: Specimens were obtained from Endoscopy Unit, Internal Medicine Department, Faculty of Medicine, Beni Suef University Hospital, Egypt. Thirty patients were subjected to detailed history and different sampling; gastric biopsy, oral and stool samples. The oral and gastric samples were processed and cultured. Thereafter, microscopic examination and rapid urease tests (RUTs) were conducted. The isolates were identified and evaluated for their antibiotic susceptibility to several antibiotics. Results: The selected patients had a mean age of 36.23 + 6.317 years. They included 17 males (56.7%) and 13 females (43.3%). 90% of the cases were found positive by culture of the gastric biopsies, while, 96.7% were positive in oral cultures. 92.5% of the gastric samples showed positive results by microscopic examination, however, RUTs were positive in 63.3% of the gastric samples and in 73.3% of the oral samples, meanwhile, 66.7% of patients were found positive by testing their stool for H.pylori antigens. The prevalence of resistance among gastric and oral isolates to Amoxycillin, Amoxycillin/Clavulinic acid, Ampicillin/Sulbactam, Clarithromycin , Tetracycillin and Metronidazole were; (3.7 and 17.2 %), (11.1 and 24.1 %), (11.1 and 20.7 %), (11.1 and 24.1 %), (25.9 and 37.9 %) and (96.3 and 100 %) respectively.  Conclusion: There is an evidenced association between gastric affection and oral H. pylori recognition that even exceeds stool detection of H. pylori antigen. Moreover, continuous evaluation of antibiotic susceptibility should be carried out and clinicians should be aware about it to select the appropriate empiric regimen for H. pylori eradication.

Abstract: One of the important data mining techniques is association rule finding. Apriori is the most famous algorithm based on this technique. But it has a major weakness which cannot calculate the minimal value of support and confidence and these parameters is estimating intuitively by the user and this has an important effect on the algorithm performance. Main goal of this paper is to presenting an optimal method to find suitable values of minimum threshold for support and confidence by means of Binary Particle Swarm Optimization. Data used for the paper is a 4000 random records sample from Foodmart 2000 Database. Implementation of the proposed method has been done using R2010b version of MATLAB software. Proposed algorithm improves the performance of association rule mining by automatically setting suitable values for minimum support and confidence thresholds..

Abstract: A metabolic disease technically refers to altered metabolism, but as used in this context refers to conditions which have their origin in nutrition or management as contrasted to infection. There are a number of such conditions which can occur with sheep and goats, but seldom represent a major constraint under commercial conditions. Included in these are acidosis, bloat, grass tetany, milk fever, posthitis, swelling disease (edema), urinary calculi, white muscle disease, etc,. Few of these actually cause serious troubles with goats under grazing conditions.

Abstract: This study was carried out to evaluate the effects of feeding ensiled mixed tomato and apple pomace (EMTAP) on blood metabolites and chewing behavior of dairy cow. Six multiparous Holstein dairy cows in mid lactation were used in 3×3 Latin square design and fed alfalfa hay plus concentrate mixture with three levels replacement with EMTAP (0, 15, 30%) during 63 days. Results showed that, differences between treatments were significant. Feeding EMTAP resulted in higher glucose, cholesterol, BHBA, triglyceride, and total protein (P<0.01) concentrations then control diet. Data showed that, total eating time (hours per day) was not significantly (P > 0.05) affected by treatments, but time spent eating, ruminating and total chewing activity per daily intake (kg) of DM and NDF decreased significantly with increasing EMTAP in diet. It was concluded that, EMTAP can efficiently replace up to 30% alfalfa hay. The nutritive value of tomato and apple pomace could be improved when they are used together (50:50) in dairy cows diet.

Abstract: Children with idiopathic nephrotic syndrome (INS) may be at risk for metabolic bone disease (MBD) because of biochemical derangements caused by the renal disease, as well as the corticosteroid effects on bone. We studied 70 children with INS for clinical, biochemical, and radiological evidence of MBD. These patients were divided into two groups: 55 frequent relapsers (FR; group I), and 15 infrequent relapsers (IFR; group II). Thirty healthy children matched for age and sex constituted the control group. Bone mineral density (BMD) of these children was evaluated by the Achilles Express Quantitative Ultrasound (QUS) device. Univariate and multivariate analyses were performed to analyze factors predictive of low BMD T- score. We observed that nephrotic children had significantly lower mean BMD T- scores compared with controls (-1.99 ± 0.74 versus -0.39 ± 0.87; P = <0.0001). Also, children in group I were found to have significantly lower mean BMD T- scores compared with group II (-2.1± 0.67 versus -1.31± 0.64; P = <0.0001). We also observed that 32.7% of group I had osteoporosis compared to none of group II (P= 0.01). Significantly higher doses of steroids over longer duration of therapy were administered to group I compared with group II (P = < 0.0001 and 0.0004 respectively). On multivariate analysis, the only factor found to be predictive of a low BMD T-score was greater cumulative steroid dose (P= 0.02). We concluded that children with INS are at risk for MBD, especially those receiving higher doses of steroids. Regular BMD evaluation and appropriate therapeutic interventions are recommended for these children. The role of prophylactic therapy in such patients needs to be further investigated.

Abstract: Divorce is an effect of several complicated psychosocial causes. It is an obvious reason for the underlying conflicts, lacking the balance and harmony of a relationship, which lead couples through a decision making process to end up their marriage. In all cultures, divorce has not been welcome. Reviewing statistics and studies on its causes that strived to find solutions for its reduction, indicates the significance of divorce and the traces of its negative effects left on various aspects of the human society. Divorce, either directly or indirectly, affects the mental health of couples, children, relatives and friends. The lack of comprehensive and inclusive studies on this issue urged us to set the aim of this study to identify the consequences of divorce.

Abstract: Nowadays it's believed that most of the accidents in industries are due to inconsideration and mistakes made by worker rather than errors in equipment and machines. So it seems that implanting an appropriate HSE culture would be a useful step toward a decrease in workplace accidents. Obviously developing an HSE culture first corrects individual behaviors then decreases human errors. Although implantation of an HSE culture deals with a number of factors, based on the results of the current study, management is the key factor. In fact values, incentives and behavioral patterns that show commitment to work methods and abilities of an HSE culture, are the main material which build the HSE culture. This study mainly discusses HSE cultures including commitment, leadership, policy, strategic objectives, organization, documentation, resources, risk assessment and management, planning, stability and revision and auditing. In this study, 175 employees of Arvandan Oil and Gas Company were chosen by Morgan table out of 320 employees then the questionnaires were distributed among them. Reliability and perpetuity of the questionnaire was calculated through Cronbach's alpha (0.971). Data from the questionnaire was transferred to data bank and statistical analyses were conducted by SPSS19 software. The desirability of the HSE culture was classified in a 5-point range using Likert's scale, ranging from "completely desirable" to "completely undesirable". Results of T and Friedman test showed that cultural elements of HSE are in a desirable level in Arvandan Oil and Gas Company.

Abstract: The goal of the present research is to examine the relationship between locus of control and marital satisfaction of couples. The method of this research is descriptive one and of correlation kind. Statistical population includes the married students of Islamic Azad University of Sari. Research sample includes 62 couples who were selected by multi-step clustered sampling method. Research tools include locus of control (Rotter) and marital satisfaction (Enrich). Data was analyzed using of the methods of descriptive statistics and deductive statistics (The agreed correlation coefficient, X2 square, and T-test). The findings showed that there is a significant relationship between internal locus of control and marital satisfaction of the couples. Also, results showed that there is no significant difference between the gender and the kind of locus of control, gender and level of marital satisfaction of the couples. Regarding the finding of the research, couples who suffer from decrease and dissatisfaction in marital relationship, have external locus of control, therefore, for improvement of marital relationship problems and having a coordinated, attractive and satisfactory marital relationship, it is suggested to replace internal control instead of external control.

Abstract The basis for pesticide use in agriculture is that costs related with pesticide pollution are to be reasonable by its benefits, but this is not so apparent. Regarding the benefits by simple economic analysis has improved pesticide use in agriculture and thus produced pesticide persuaded public harms. This paper effort to explore the research gaps of the economic and social concerns of pesticide use in developing countries, predominantly with an example of India. We contend that although the negative sides of agricultural development. We assume that, if these difficulties are grasped and accounted for, the remunerations from the current use of pesticides could be remunerated by the costs of pollution and ill human health. This paper also explains different pathways and mechanisms for disregarding. In view of prospective and overall negative impacts of pesticide use, we recommend alternate ways of controlling pests such as unrestricted unified pest management along with education and training activities.

Abstract: Objective: To explore the diagnosis, etiology, clinical feature and treatment of advanced esophageal carcinoma with no obvious superficial mucosal alteration. Method: Between December 2004 to December 2009, we treated eight patients who suffered advanced esophageal cancer but were not found obvious superficial mucosal alteration by fiber-esophagoscopy. The bulging mucosa was smooth and biopsy examination showed chronic mucosal inflammatory. Without definite diagnosis, the patients (five men and three women) underwent esophagectomy in our department. Clinic data and tumor characteristics of them were analyzed retrospectively. Result: Two patients died after the operation, while the other six recovered uneventfully. Postoperative histological examination confirmed six squamous carcinoma (SCC) and two adenocarcinoma (ADC) and the tumor originated in the lamina propria mucosa, muscularis mucosae or submucosa, while mucous epithelium found no tumor cells. Until now, one patient is still alive more than five years, one survived about five years, three survived less than five years, and another one had been dead within two years. Conclusion: As the symptom of this kind tumor is mild and the diagnosis is difficult before surgery, the surgeons should be patient when they encounter these patients. Long time follow up is very important.

Abstract: This paper examined Semi- Settled Pastoralists’ knowledge and Utilisation of HIV/AIDS Prevention Techniques in South West Nigeria. The derived savannah areas of Oyo and Ogun states of Nigeria were selected for the study due to high concentration of semi-settled pastoralists who are distributed within 5 and 10 Local Governments Areas (LGAs) in Ogun and Oyo States respectively. Fifty percent of the LGAs were randomly selected from each state. Ninety-four semi-settled pastoralists’ households were randomly selected from 1,174 in Ogun State, while 236 households were selected from 2,942 in Oyo State. An adult respondent was selected in each of the households to give a total of 330 respondents for the study. Structured interview schedule was used to collect data relating personal characteristics, sources of HIV information and utilisation of HIV/AIDS prevention techniques. The result shows that the mean age of the respondents in Ogun State, Oyo State and across the states were 36.3, 38.7 and 38.0 respectively. Across the states, about 83.0% of the semi-settled pastoralists were below 51years of age. In terms of knowledge on HIV/AIDS prevention techniques were presented. Semi-settled pastoralists had high knowledge on 15 items. These include, sharing syringes / needles (), sharing of spouse (), sharing tattooing instrument () and screening blood before transfusion (). On the other hand, semi-settled pastoralists had low knowledge about items such as HIV can be transmitted through air (), HIV transmission through food (), pre-marital sex () and use of condoms () among others. Semi-settled pastoralists had high utilisation in 10 HIV/AIDS prevention techniques across the states. These include, screening of blood before transfusion (=0.8); usage of new needles for tattooing (=0.7); usage of new syringes and needles for injection (=0.7) and use of personal blade / razor for cutting my nails (0.7).

Abstract: Looking at valuable tissues, it is noticed that cultural spaces have the most important position in urban identity.   City identity is the resultant of all forces for changing the city to a cohesive physical-social arena and to strengthen cultural-social prestige and structural phenomenology of urban identity using the effects of these arenas. What creates the urban identity is the coordination between architectural and urban spaces with the performance and the content of physical-social phenomena in a city.  Cultural performance spaces are among the most important of these spaces which have the important and valuable role in the hierarchy of urban identity. This study investigates the importance and clear position of the spaces with the cultural using for strengthening and promoting the urban identity. This research in regard to implementation process is qualitative, descriptive and then analytical. The investigation and the concepts are based on library and documentation methods. The results indicate that cultural spaces can be considered as one of physical-social phenomena of a city. Despite of different problems in the design, cultural spaces should be built in coordination with the framework determined in the principles of urban identity. Hence in creating these spaces, a suitable design of the city identity can be imaged by benefiting from past experiences and new thinking. Whatever systematic principles of urban and architectural design have more effective communication with urban identity structure, the stability of urban identity will be provided.

Abstract: The aim of this paper was to describe the anti-angiogenesis properties of the two tumstatin synthetic peptides, T3 and T7, which corresponded to 69-88, 74-98 respectively of amino acid sequence of tumstatin, on infantile hemangioma endothelial cells in vitro. The MTT assay results demonstrated that the tumstatin peptides, T3 and T7, could inhibit the proliferation of hemECs in the culture media with 0.025 volume fraction of FBS in a dose dependent manner. When the volume fraction of FBS in the culture media rose, it was deduced that more gowth factors exerted their effect promoting proliferation to the extent that the difference between different dose groups were covered up. Additionally, it was observed in the tumstatin peptides groups that the cell morphology had changed, the cells became contracted and sparse compared with the control group.Further, the cell cycle assay demonstrated that the two tumstatin peptides could arrest the cell cycle at the G0/G1 phase in the hemECs.This results were consistent with the prior MTT assay results, and showed the reasonable cause why the two peptides could inhibit the hemECs proliferation. Moreover, it was demonstrated that the two tumstatin peptides could inhibit the migration of hemECs by the in vitro wound healing assay.

Abstract: The aim of the present study was to detect the polymorphism in exon 26 of apoB gene in Khazak breed Chickens. Apolipoprotein B (apoB) is the primary apolipoprotein of low density lipoproteins, and is responsible for carrying cholesterol to tissues. The apoB gene is located on chromosome 3 and consists of thirty exons and twenty- nine introns. in this study, sixty sample selected of laying chickens native khazak breed to the region of Sistan and Baluchestan and DNA genomic was extracted from follicle end feather and genotyping by the PCR-RFLP method. The PCR product was digested with restriction enzyme AcyI and then separated electrophoresis using 2% agars gel. A mutation was identified on exon 26 in chromosome 3. AA, AB and BB Genotypes were detected in this population, respectively with frequency of 16.7, 28.3 and 55 percent. The frequency of an allele and B allele was estimated, respectively 0.3083 and 0.6917 percent. The B allele was more frequent than B allele and BB genotype was more frequent than other genotypes in this population. Chi square(χ2) test and G test showed Hardy- Weinberg equilibrium in the population and this polymorphism was approved using sequencing method with ABI sequencing system .Thus, according to the results observed and the important role of this gene in egg production, this gene appears to be an important candidate gene in native chickens used in breeding program.

Abstract: Goats are known to be both more able and more willing than some species to select and consume a wider variety of material and to select those plants or plant parts having higher nutritive value.The type of nutrients required by all animals is essentially the same and these are energy (carbohydrates, fat), protein, minerals, vitamins and water. Although fat is shown here as an energy source there does appear to be a limited requirement for fat itself, but this is not considered to represent a problem. These nutrients provide the raw materials or resources for body maintenance, muscular activity, growth (meat production), reproduction as well as milk and fiber production. Nutrients interact to serve different functions which will be reviewed briefly. Energy is obtained from dietary carbohydrates (sugars, starch and fiber) and fats. Protein is the nutrient which might be considered the second most limiting for both fiber and milk production in the Angora goat. Vitamins are a group of compounds which are required in minor amounts. Generally these are grouped as the fat soluble vitamins (A, D, E and K) or the water soluble vitamins (C and the B complex group).

Abstract:Objective: Evaluating the effect of antenatal betamethasone on the biophysical profile and Doppler indices of umbilical and middle cerebral arteries. Materials and Methods: Twenty-five preterm labor singleton pregnancies (gestational age, 26-34 weeks) were studied prospectively. These patients received two consecutive doses of betamethasone 24 hours apart to accelerate pulmonary maturation. Fetal biophysical profile (BPP) and Doppler assessment were performed twice, on admission and 48 hours after administration of the first dose. The mother recorded fetal movement before, during and after the study periods. Comparison was made between biophysical profile score, fetal movement and Doppler indices of the umbilical and middle cerebral artery before and after betamethasone administration. Continuous data were compared by paired t test and dichotomous data were compared by McNemar test between pre and post treatment evaluations. The statistical significance was set at 0.05 levels. Results: Twenty-five women–median age, 26 (19-42) years; median of gestational age, 32 (26-34) weeks–which were referred to Imam Sajjad hospital, Yasuj from August 2010 to December 2011 were enrolled into the study. There was significant different in fetal movement before and after betamethasone administration (p=0.004). The frequency of BPP scores ≤8 increased from 13 to 21 subjects (p=0.039) at post treatment evaluation which was significant statistically. There was statistically significant difference in the reduction of umbilical artery PI (0.10) (95%CI: 0.01-0.19) and RI (0.07) (95%CI: 0.08-0.06)), but these changes were not important clinically. The mean changes of MCA PI and RI were 0.01 (95% CI:-0.16-0.19) and -0.01 (95% CI:-O.08-0.06), respectively. Conclusion: After betamethasone administration, fetal movement, BPP scores and umbilical artery indices were decreased, while MCA Doppler indices were not affected.

Abstract: Today, wireless communication systems will be built for cooperation rather than for more coexistence. Cooperative communication is a hot topic of current research and many researchers believe it to be the next big step after multiple-input multiple output systems. The important idea is that multiple nodes cooperate in order to increase the link quality, reliability and data rate of the system. In the future, the density of active nodes competing for a common wireless channel in cellular as well as access or ad hoc networks will increase significantly. Therefore, node cooperation is an efficient means of achieving these gains.

 Abstract: The design and development of an appropriate simulator for C2 complex systems is field of research. Researchers in this field are trying to create simulation models to describe the behavior of C2 complex systems. Like any other application softwares, the design and development of C2 complex systems simulator needs a methodology to make analysis, design, and development more accurate and produce a high quality software simulation. C2 simulator software usually models and simulates C2 complex systems using multi agent approach. However, the multi agent simulator is basically different from the agent based business applications. Therefore for developing former one we need a special methodology. In this paper, a methodology based on Capra cognitive framework for modeling and simulating C2 complex systems has been proposed. This methodology determines the main steps for the analysis, design, and development of C2 simulator. In addition, since the proposed methodology utilizes the basic concepts of complex systems, it may be used for modeling the main concepts and components of other complex systems such as ant colony and stock market.

Abstract: This paper reports - on the basis of a questionnaire survey of the largest Iranian contractors - a perspective of construction risk, and the effective actions taken for the management of such risks, particularly those of time and finances. The study, the first inIran, focuses on the assessment, allocation and management of construction risks. The paper also presents two types of riskmanagement methods: preventive, which are effective at the early stages of the project life, and mitigative, which are remedialactions aimed at risk minimization during construction. The research found that contractors show more willingness to accept risksthat are contractual and legal-related rather than other types of risks. The research results also indicated that the application of theformal risk analysis techniques in the Iranian construction industry is limited.

Abstract: In the present study, the morphological and morphometric characterization of two species of digenetic trematodes infecting the large intestines of the common chameleon Chamaeleo chamaeleon (Reptilia: Chamaeleonidae) were described by means of light microscopy as a first description. 30 and 37 out of 115 (26.1 % and 32.1%) of this lizard species were found to be naturally infected with Postorchigenes sp. (Trematoda: Lecithodendriidae) and Malagashitrema sp. (Trematoda: Homalometridae) respectively. Postorchigenes sp. possesses a body which is oval, spinulate with an oral sucker bigger than acetabulum. The prevalence of Postorchigenes sp.  reported from the present study were agreed with the previous studies carried out by Kennedy et al. (1987) who described a three species of digenea from seven species of lizards in Idonesia. Malagashitrema sp. possesses oral sucker larger than acetabulum. The presence of Malagashitrema sp. proved that Malagashitrema is a genus with species linked to Chamaeleo spp. These trematodes adapted to different areas, making their presence are possible in different geographical regions in the world and appears to be a species adapted to Chamaeleo spp.

Abstract: The combination of hypertension and proteinuria such as preeclampsia during pregnancy markedly increases the risk of prenatal mortality and morbidity.  24hour urine protein estimation is the gold standard for assessment of proteinuria. This study was undertaken to determine whether an 8hour & 12hour protein estimation correlated with that of a formal 24hour collection. The study population included 65 pregnant women over 20 weeks gestation with hypertension admitted for assessment of proteinuria in Bandar Abbas Dr. Ali Shariati hospital. Urine samples were collected over 24hours with the first 8hours, next 4 hours, and remaining 12 hours collected in separate containers. The urine volume, and total protein levels were measured in the 8, 12, and 24 hours samples and compared each other. Of 65 patients 35 had no proteinuria, 27 had mild proteinuria and 2 had severe proteinuria. 8 hour sample predicted significant proteinuria with sensitivity of %63, specificity of %91 positive predictive value of %86 and negative predicative value of %82. Total protein values for 8 and especially 12hour sample correlate positively with values of 24hour sample for patients with proteinuria.

Abstract: Many pregnant women worry about labor pain and they are mostly willing to perform cesarean delivery. Nowadays many pharmacological and non-pharmacological methods are used to reduce labor pain. The present study aimed to investigate the effect of changing a woman’s position in the active phase of labor on the level of feeling pain during the delivery. This clinical trial was performed on 400 pregnant women in the active phase of labor who were selected according to the purposive sampling method. Samples were asked to fill out the questionnaire and personal questions, after that they placed in a sitting position and then after 15 minutes they changed their position and placed in a supine position. Changing the position iterated every 15 minutes and the level of pain in lower back and abdomen were determined by a pain ruler and finally the results were recorded. Data were analyzed through independent T-test and Chi-square.The majority of women who were in sitting position had lower abdominal pain rather than who were in supine position and changing the position from sitting to supine intensified the pain more than before. There is a significant relationship between a woman’s position during labor and the level of feeling pain in lower back and abdomen in the active phase of labor (p=0/000). Sitting position can reduce lower back pain and also lower abdominal pain; it can also change the level of severe pain into the moderate one and the level of moderate pain into the mild one in the active phase of labor.

Abstract: In analyzing the issue raised, first the mood, morality and mystical morality were defined, and the Islamic and non-Islamic roots of asceticism, and mysticism were studied. Then, the reasons for developing the mystical morality, including anti oppression, introspection, popularity, political power and the equality of the morality with the mysticism, and the asceticism foundation were considered. Then, through comparing the specifications of this morality and the needs of the modern societies, it was found out that the mystical morality (with roots in asceticism and mysticism) is able to solve the spiritual problems and the ethical needs of the societies. Moreover, it was explained that the specification of tolerance and intolerance against the strictness of the religion methods is regarded as the superiority of the mystical morality.

Abstract: Voluntary disclosure reduces information asymmetry between investors and stakeholders. In this study, to evaluate different decision-making styles, a cognitive and behavioural model is used. The field of this research are in the Processing "Brunswick Leans Model" is placed in behavioural accounting. This research uses a quasi-experimental method. The research is conducted in 2012 in Tehran Stock Exchange (TSE.).  For purposes of this study, an Experimental group (176 respondents) and a control group (158 respondents) in is divided into four new ones, which represent the four dominant styles of decision-making, namely directive, analytical, conceptual, and behavioural. As an addition, investors are divided according to their brains’ dominant style of decision-making and cognitive complexity so that uncertainties about the tolerance level are classified. Evidence shows that those who have their left brain as more dominant are likely to use more items, on average, to process information. As an addition, Behavioural decision-making style uses lowest items to process information than other styles. Indeed, the results show that all styles in the Experimental group have less information asymmetry than the control group. These findings support the voluntary disclosure of information by companies to reduce the level of information asymmetry that the market offers.

Abstract: Background: Obesity is a major susceptibility factor leading to the development of various conditions of the metabolic syndrome. In obese rats, slowing of motor nerve conduction velocity was observed. Fatty acids metabolism disturbance is very important in the occurrence of peripheral neuropathy. The aim of this work is to consider the role that balanced diets high in omega 6&9 PUFA (corn oil) or supplying rats with omega 3, play in modulating the impaired nerve function in obese rats. Methods: Thirty two adult male albino rats were randomly assigned to receive normal chow (NC) (n=8) or high fat diet HFD (n=24), for 12 weeks. After 12 weeks, body weight and body mass index(BMI) were measured and the NC group(n=8) continue their normal chow diet, Group 1 (NC) and served as a control group and the obese rats were randomly divided into 3 groups, 8 rats each: Group 2: Ob + HFD group, they continue their high animal fat diet, Group 3: Ob+HFD + corn oil group, they are obese rats received high fat diet containing corn oil and Group 4: Ob + HFD + Omega 3 group, they are obese rats, fed high animal fat diet supplemented with omega 3 (0.4 g/kg) daily. After five weeks, the final body weight was measured and BMI was calculated and blood samples were collected for measuring fasting plasma glucose level, insulin level and homeostasis model assessment of insulin resistance (HOMA-IR) test were evaluated. Plasma cholesterol, triglycerides and free fatty acids (FFAs) were measured. The rats were then killed and sciatic nerves were carefully dissected for measuring the nerve conduction velocity (NCV). Superoxide dismutase activity (SOD), malondialdehyde (MDA) and tumor necrosis factor alpha (TNFα) were estimated in the nerve tissue of the 4 groups. Results: The results of this study showed a significant increase of body weight (gm) and BMI (kg/m2) in high fat diet group (p< 0.05) after 12weeks of the start of the diet when compared to the control group (NC). There were significant elevations in the final weight (gm) and BMI (kg/m2), a significant elevation in insulin level (µIU/l) and HOMA-IR test, a significant increase in nerve malondialdehyde (MDA), and tumor necrosis factor alpha (TNFα) and a significant decrease in superoxide dismutase activity (SOD) and nerve conduction velocity (NCV) (m/s) after 5weeks of high fat diet in (Ob+HFD) group, when compared to NC group. Changing diet composition for 5weeks in Ob+ HFD+corn oil and Ob+HFD+omega 3 groups, did not induce any significant variation in body weight, BMI, or fasting blood glucose level as compared to Ob+HFD group. Insulin level (µIU/l) and HOMA-IR test were significantly decreased in Ob+ HFD+corn oil and Ob+HFD+omega 3 groups compared to Ob+HFD group. Plasma cholesterol levels (mg/dl), triglycerides (mg/dl), and free fatty acids (FFA) (mmol/l) were significantly decreased after 5weeks diet in Ob+ HFD+corn oil or Ob+HFD+ Omega 3 groups when compared to mean values of Ob+HFD group. Tissue malondialdehyde (MDA) and tumor necrosis factor alpha (TNFα) were significantly decreased but superoxide dismutase (SOD) activity was significantly increased in Ob+HFD+corn oil and Ob+HFD+omega3 groups compared to Ob+HFD. NCV(m/s) in Ob+HFD+ corn oil group was significantly increased compared to Ob+ HFD and their values in Ob+HFD+ corn oil group showed no significant variation as compared to NC group. While there was a significant increase in NCV in Ob+ HFD+Omega 3 group as compared to Ob+ HFD group, there was still a significant decrease compared to NC group. Conclusion: The results of this study may have important clinical and speculative implications. Corn oil or omega 3 supplementation may be effective in obesity induced neuropathy. The mechanism of their effects is multifactorial including improving insulin sensitivity, correction of dyslipdemia, reducing oxidative stress and an anti-inflammatory effect. This possibility should be carefully considered and examined in future trials of essential fatty acid supplementation.

Abstract: Well testing is of great importance in petroleum engineering, to have a kind of firsthand knowledge and estimating formation permeability, wellbore damage/ skin, etc. These parameters are further required to estimate production rate from a well and at the same time gives an idea of its productivity. These reservoir related parameters calculation is strongly dependent on formation thickness. Any uncertainty in formation thickness leads to ambiguous results, which in turn influences further reservoir development studies. This study focuses on analyzing the impact of such uncertainties and highlighting their effect on the resulting estimations, while considering cases of gas, oil and multiphase flow reservoirs one by one. The obtained results in case of gas reservoir shows that uncertainty in formation thickness has strong influence on well test estimated data.

Abstract: Formation thickness is of vital significance in estimating different reservoir parameters in oil reservoirs. Any error or uncertainty in formation thickness can contribute as tremendous source of error while estimating different parameters based on well testing, like, permeability, radius of investigation, etc.   In this second part of the study, a pressure-buildup test has been analyzed, while incorporating the uncertainties in formation thickness. The effect of these uncertainties has been included in different calculations like, permeability, skin-factor, radius of investigation, wellbore storage, etc. The results show that the uncertainty in formation thickness affects all the aforementioned parameters, though the degree of influence can be different.

Abstract: While performing reservoir related studies either conducted by an engineer or a production geologist, one have to deal with number of uncertainties arising from different sources based on the manner by which different properties required to be used as an input while evaluating buildup well test data. Out of the required input parameters, payzone thickness have a kind of key significance, as most of the well test estimated data is directly or either indirectly depend on it. Most of the petroleum reservoirs have multiphase flow, so in this study buildup test data for multiphase flow have been analyzed while incorporating the payzone thickness uncertainty.

Abstract: There are several factors influencing the water quality based on its usage. The quality of drinking water is of the vital concern for human health and life. An essential attempt has to be done to develop a water quality index (WQI) corresponding with different conditions and characteristics of the relevant river or water body such as geographical, hydrological, discharge rate and pollution sources. The index is not specifically focused on human health or aquatic life regulations. However, a water index based on some very important parameters can determine a simple indicator of water quality. In the present study, the Taleghan water quality has been evaluated by available NSF water quality index. Subsequently, the nine present NSF parameters’ weights have been changed and modified using the analytical hierarchy process (AHP) method as well as experts’ opinions in the field in a way to satisfy local conditions. In the newly developed WQI, more weights are given to relation with these parameters it can be said that the factors like dissolved oxygen (Do), fecal coliform (F.c) and biological oxygen demand (BOD) when compared with NSF-WQI.

Abstract: Shape Memory Alloys (SMAs) are types of Smart Materials (SMs) which are used in many industries nowadays. The high hardness value and the intelligence of these alloys have made the traditional machining processes not cost effective or incapable of machining ability these metals. The NiTi alloy is one of the SMAs, which are used in aerospace and medical industries. Electrical Discharge Machining (EDM) is a known method for the machining of shape memory alloys. In this research, the effect of input parameters of electrical discharge machining including the voltage (V), discharge current (A), pulse-ON-duration (μs), pulse-OFF-duration (μs), tool material and the dielectric on the material removal rate (MRR), tool wear rate and surface roughness has been investigated for NiTi alloy. Graphite tools and de-ionized water have been used for the machining operation, and the Taguchi’s method, LI8 orthogonal array and the ‘Minitab R.16.1.1’ software have been employed for the design of experiment. The results indicate that with the increase of discharge current, the tool wear, material removal rate and surface roughness increase. The increase of voltage causes the reduction of tool wear and material removal rate, but it has little effect on surface roughness. With the increase of pulse-ON-duration, the surface roughness increases and the material removal rate diminishes. Also the increase of pulse-OFF-duration, up to a certain time, leads to the increase of material removal rate and tool wear rate (TWR) and the reduction of surface roughness.

Abstract: Although environmental costs are only one of the many costs incurred by businesses, they deserve management’s attention. For companies in the service sector with office environments, better insight into environmental costs can lead to them being reduced while environmental performance is improved with costs being offset through the recycling or sale of waste and improved costing of services It will also help with the justification of environmental improvement initiatives, and support of a company’s environmental policy, management system or data collection for public reporting. Environmental management accounting can be used as a tool to reap these benefits, and refers to “the process of identifying, collecting and analyzing information about the environmental costs and performance to help an organization’s decision making.”

Abstract: A group of bacilli phenotypically screened for synthesis and intracellular accumulation of PHAs granules by the use of Sudan black B stain, eight strains were detected. Pair of specific PCR primer was designed and applied for genotypic detection of phaC synthase gene. Approximately, 760 bp DNA fragment was successfully amplified in the eight strains. Among the positive strains, Bacillus sp SW1-2, produced 40 g/L of the biopolymer during growth on modified E2 medium supplemented with glucose after 36 h. Spectroscopic analysis by C13 NMR and H1 NMR revealed four narrow peaks (lines) (CH3; 21.2 ppm, CH2; 42.7, CH; 68.5 and C=O; 169.7 ppm) and 3 groups of signals (2.45, 2.58 and 5.2 ppm) were identical and characteristic to polyhydroxybutyrate (PHB); respectively. Furthermore, the amplied PCR fragment, from genomic DNA of Bacillus sp SW1-2, was cloned in pGEM-T-Easy vector and sequenced with the universal T7 and SP6 primers. It showed 99% identity to phaC gene for polyhydroxyalkanoate synthase of many B. megaterium strains deposited in Genbank. While showed 73% and 72% identity to synthases of Bacillus mycoides and Bacillus sp. INT005, respectively.

Abstract: The purpose of this study is to evaluate the efficiency and ranking of 15 Restaurants in Iran, paying attention to efficiency improvement using a data envelopment analysis (DEA) model. The model considers three inputs (monthly working hours, branch area (square meters), and years of experience as manager) and two outputs (monthly number of customers who bought something from the branch, and monthly sales in USD). The results indicate that data envelopment analysis is a Useful tool to evaluate the efficiency of Restaurants. Moreover, the results show that Noor restaurant and Nemoone restaurant is the most efficient restaurants Compared to other restaurants. Restaurants or other service providers should find this alternative DEA model helpful and more flexible in re-examining their resource utilization and possibly reshuffling their resource pool.

Abstract: Increased availability of appropriate software and hardware has built a new horizon in educational institutions in order to facilitate electronic learning, especially the development of global web net. Importance of this problem in medical sciences which is associated with human life is twice. Hence the aim of this study was phenomenology of scientific board’s views about electronic learning in Mazandaran University of Medical Sciences.In this descriptive study 40 scientific board members of Mazandaran University of Medical Sciences were enrolled. The method was based on goal and information was collected on basis of deep and semi-structured personal interview, and encoded and analyzed with Smith method. The results were grouped in 5 clusters and 15 groups. The main extracted cluster included: information, public facilities, availability, organization, language and comment evaluation. According to some advantages of electronic learning, there is no doubt about necessity of electronic learning. But the most concern in using electronic learning is expressed in aspect of information and public facilities, availability and comment evaluation that prompt lack of tendency and affinity of scientific boards in using this method, mentioning that adaption of some existing processes in world and using other countries experiences in achieving the most comprehensive model in university from Educational Development Center is unavailable.

Abstract: In this study, the role and importance of management accounting in organizations in achieving the organizational goals has been discussed. Management accounting in the world has enjoyed a rapid growth and dynamics and has regularly presented new intellectual products to the managers and leaders of the organizations. In addition, management accounting, as new business knowledge, can help the managers in successful interactions with one another with a variable environment through providing information. Managers in both profit and nonprofit organizations have an interaction with their own management accounting system. Sometimes, a manager uses the management accounting system for planning and decision making and in some other times, this system measures the performance and affects the managers’ behavior. Management accounting system is considered as a source of information for making planning decisions and at the same time it is considered as a part of control system of an organization. Management accounting helps to create value in an organization through improving decision making process and control of organizational members.

Abstract: The food industries in Iran is widely recognized as a 'sunrise industry', with a huge potential for uplifting the agricultural economy, creating large scale processed food manufacturing and food chain facilities and resulting in the generation of employment and export earnings.   Due to the importance of Food Industries in Iran this paper estimated and investigated the efficiency in this industry. The stochastic frontier approach is applied. The result showed that the measure of the   average technical inefficiency of the Iranian food industries was 26%. In other words, the food industries of Iran are only 74% technically efficient. The important factors that affect on efficiency in food industries of Iran are Education (ED), skilled (SK), specialization (SP) and workers insurance (IN). All the factors have the expected significance values and are consistent with theory.

Abstract: Motivation theories and their application constitute one of the broadest issues among researchers of organizational behaviour of which motivation is the most fundamental issue.Therefore, in this paper, four new theories of motivation are studied to explain the effects of these theories in organizations. The results show that applying these theories in the organization improves employee performance and job satisfaction, and that using these theories, can be justified, the rate of productivity, absenteeism and staff mobility, in the use and application of these theories needs to be carefully because the only motivating factor in the break back, will not be enough to boost performance. These theories are three needs theory, equity theory, expectancy theory and attribution theory.

Abstract: One of the biggest contemporary challenges of management in service industries is providing and maintaining customer satisfaction. Service quality and customer satisfaction have increasingly been identified as key factors in the battle for competitive differentiation and customer retention. Service quality brings many advantages to the company. It allows the company to differentiate itself from its competitors by increasing sales and market shares, providing opportunities for cross-selling, improving customer relations and thus, enhancing the corporate image. It results in the satisfaction and retention of customers and employees, thus reducing turnover rates. The purpose of this research is to survey relationship between service quality, customer satisfaction and behavioral intention in the private banks, to measure service quality we used an adaptation of the SERVQUAL scale. To test hypothesis used structural equation models and LISREL Software. Finally second and third hypothesis are accepted also research results suggest that dominant dimensions of Service Quality in the Private Bank Are: 1) Responsiveness., 2) Knowledge., 3) Tangibles and  4) Recovery.

Abstract: Emergency department is the first place that medical team gets contact with the patient. In order to have higher standards in traumatic patient care, continuous quality control is an essence and time is an important factor for this perspective in emergency department. Current study evaluates management of traumatic patients visiting emergency department (ED) in Imam Reza hospital by assessing length of stay and its effective factors such as Routine Trauma X-rays. Between April and December 2011, 300 traumatic patients visiting emergency department, Imam Reza hospital were randomly studied. Time needed to perform the routine trauma x-rays (lateral cervical vertebra, AP chest and AP pelvis radiographies), and the length of stay (LOS) in the ED were recorded. Mean physician and nurse first visit was 7.93±0.47 and 11.91±9.38 minutes, respectively. X-rays in was performed within 70.30±53.08 minutes. Mean surgery and neurosurgery visits were obtained within 37.40±3.16 minutes and 33.48±2.10minutes, respectively. The average LOS in the ED was 404±238.51 minutes. There was no significant difference in LOS in the ED according to age, gender and trauma severity. Total ED stay of trauma patients in our ED was found to be significantly longer than other advanced centers. Structural improvement of emergency department and diagnostic modalities availability could reduce LOS in ED.

Abstract: Leiomyomas constitute the most common female pelvic tumor, becoming increasingly prevalent with age. Although transabdominal ultrasound is usually used for observation of the large uterine tumors outside the focal zone of the transvaginal transducer, but transvaginal ultrasound is the standard imaging modality for this purpose. Recently with introduction of transvaginal color Doppler ultrasonography some studies have been performed on uterine artery blood flow in myomatous uterins, however these studies are scanty. Our object in this study is the determination of probable particular effects of leiomyoma on blood flow in uterine arteries. In this cross sectional study 50 women with myomatous uterine and 50 healthy volunteer woman were enrolled in the study. Transvaginal color Doppler was used for observation of uterine arteries and vascularity of myomas. The mean uterine volume was significantly lower in control group (97.00 ± 37.71 cm3) than in cases (3S1.16 ± 222.94 cm3). The mean peak systolic velocity (PSV) was significantly lower in control group (36.42 ± 9.28 cm/s) than in case group (49.34 ± 16.37cm/s). Significant correlation between uterus volume and PSV was not seen in control group but medium positive correlation between mean uterus and mean PSV was seen in case group. Mean pulsatility index (P1) was 1.59 ± 0.36 in case group and 2.40 ± 0.46 in control group. Significant correlation between mean uterus volume and mean pulsatility index (PI) in study group was seen. Mean resistance index (RI) was 0.74 ± 0.19 in case group and 0.85 ± 0.23 in control group. No correlation was found between uterine volume and number of myomas. Only in %34 cases myomas artery was detectable and mean myomas artery RI was 0.57 ± 0.18. We observed significant differences between uterine arterial Doppler indices in patients with myomatous uterins and control group. The presence of myomas result in uterine volume increasing and uterus Volume has significant correlation with PI decreasing. Also PSV has significant correlation with uterine Volume. This significant difference suggests that, we can use serial measurements in duration of treatment in monitoring response to medical treatment.

Abstract: Stepped spillways are hydraulic structures that, because of their significant capacity in energy dissipation, have been widely used by designers. Flow mechanism over them is complex and many investigations have been performed to study that mechanism. The effect of some parameters such as the number of steps in energy dissipation has not been fully investigated. In this study the latest design criteria have been reviewed and then an algorithm has been developed to design the stepped spillways which are based on the effect of number of steps. Results show that the number of steps affects the energy dissipation. With increasing the number of steps energy dissipation increases and then decreases. Thus for specific discharge and spillway slope, the number of steps can be optimized for maximum energy dissipation. By reducing design discharge the optimum number of steps increases. Research work on this subject can be continued in the future and various aspects of the design parameters may be investigated

Abstract: Background: Intermediate soft tissue tumors were included in the new WHO classification of soft tissue tumors. They were addressed as locally aggressive tumors with reports of their recurrence or even malignant transformation. This study was conducted to detect the immunoepxression of Beta Catenin and Platelet Derived Growth Factor in order to predict their potential for malignant transformation. Methods: Twenty three different intermediate soft tissue tumors were included as well as three recurrent cases diagnosed as fibrosarcoma. All lesions were prepared and were subjected to Beta Catenin and Platelet Derived Growth Factor antibodies. Results: From the 26 selected cases, 9 were Juvenile fibromatosis, 5 were haemangiopericytoma. 9 were desmoplastic fibroma 3 of which showed recurrence and were diagnosed as Fibrosarcoma. All cases of jeuvenile fibromatosis, desmoplastic fibroma and fibrosarcoma, showed positive nuclear reaction to Beta Catenin antibody. Cytoplasmic reaction of Platelet Derived Growth Factor antibody were observed in 6 cases of juvenile fibromatosis and 5 cases of desmoplastic fibroma as well as the 3 cases that showed recurrence in the form of fibrosarcoma. Conclusion: Intermediate tumors have a benign clinical course, but their clinical behavior is unpredictable.

Abstract: Chemotherapy, so far, of metastatic breast carcinoma is not curative using the currently available chemotherapeutic, hormonal or biologic agents. The treatment of metastatic breast cancer is aimed mainly at alleviation of symptoms rather than cure. The first choice of therapy is dependent on patient age, performance status, hormone receptor status, human epidermal growth factor receptor-2 (HER-2), involvement of the viscera, or enrollment of patients in investigational trials. Combination of chemotherapeutic drugs showed an advantage for survival, tumor response and time to progression, with adverse effects of these agents. It is very important, therefore, to balance between the benefits of treatment and the adverse effects and complication of therapy.

Abstract: Multiple sclerosis disease (MS) is a chronic inflammatory demyelinating disease. The aim of this study was to evaluate cervical cord changes and to determine abnormal cervical cord prevalence in the patients with MS and their comparison with vasculitis patients. In a descriptive-analytic study carried out on 50 patients with MS, 40 patients with vasculitis and 50 people as control group in Tabriz Razi hospital, we studied cervical cord changes and the prevalence of cervical cord abnormalities in the patients with MS and vasculitis. From 50 MS patients, only four people had diffused lesions in spine that were all related to Primary Progressive (P-P) type. From the 22 patients with MS, having spinal symptoms during the study, focal lesions were revealed in the cervical cord Magnetic Resonance Imaging (MRI) of eight people (36.4%) whereas the lesions were found in 28 patients with MS who had no spinal symptoms. Diffused lesions were also found in the cervical cord MRI of four patients (18.2%) who had spinal symptoms whereas the lesions were found in the 28 patients with MS who had no spinal symptoms. There was a meaningful and the reverse relations between EDSS mean and transverse cross-section of cervical cord. In every five patients with MS one patient had demyelinated lesions in cervical spine which was more obvious in progressive types and atrophy degree of cervical spine was more in the patients with P-P and Secondary progressive types compared to the patients with relapsing remitting.

Abstract: Cloud computing is very emerging technology and have economical computation over the current infrastructure. Cloud computing provides the services on the basis of as you pay as you go. Privacy and security is still at top level risk in cloud data management environment. Privacy of the data is affected as cloud users have not fully aware about the location of the data kept on servers. Data segregation is another problem during the storage of data. Identity management is a big issue that is faced by the cloud users. In the research paper we will propose a model to improve the data security and privacy in the cloud environment. Single Sign On uses the different identity management methods to enhance the privacy and security of the cloud users like OAuth, OpenId, and SAML etc. Securing the identity management is very effective method to secure your authorization and access management that makes surety to providing the secure cloud data management environment.

Abstract: Electrical Energy is the lifeline of domestic, industrial, agricultural and approximately every field of life. Generally available appliances at domestic and industrial levels are of Alternating Current (AC) nature that is they operate on Alternating Current. This type of Current can graphically be shown by pure sinusoidal wave. All of the appliances are designed to operate on pure sine wave but most of the electrical energy sources, converters and various types of Uninterruptible Power Supply (UPS) available in the market give the output which is not of pure sinusoidal wave shape and contains harmonics and interharmonics. These harmonics can cause overheating of the devices and many other problems that ultimately damage the device/appliance or at least decrease the life of electrical gadgets. This research is going to evaluate the shapes of these waveforms, their harmonics and then to establish a hierarchy among the sources on the basis of characteristics of their resultant output waveforms. For the purpose mentioned above, a very high range digital oscilloscope with ultra zoom capabilities has been used. It will provide ease to suggest a new buyer of the energy source in setting priority amongst the available alternatives qualitatively.

Abstract: As the world population is getting older, health care for elderly becomes important. Distribution of specialties related to elderly health care is highly variable. To assess the distribution of specialties related to elderly and the aged population (i.e. over 65 yrs.) a prospective analytical study was designed from 1999-2009. During this 10 year period ageing process was increasing, initially slow but rapid in the last years. Internists, cardiologists, neuro-psychiatrics, and neurologists in the beginning of period had an increasing trend and declined in the mid-period then had decreasing trends. Orthopedic surgeons were almost increasing in all of the decade.In present, the number of geriatricians are fewer than 10 in the whole country, and health policy should move toward health care providing for elderly. Keeping in mind that aging process is increasing recently, number of specialists and physicians caring for elderly should also increase. (abstract: truncated at: 144 words).

ABSTRACT: Employee retention is the leading problem, which all organizations are now facing in the international aggressive environment. While soaring employee turnover reflects on squat morale and be short of of motivation, entertainingly, seen from a different angle the nonappearance of turnover rapidly results in de-motivation because the opportunity of lateral and forward-motivation is out of action from employees. It is in opposition to human personality to stay static, performing the similar duties day in day out, with no hope of change in regular or opportunities for improvement. Moreover, the routine methods of employee motivation such as financial rewards and perks have been not here at the back in preventing employee turnover. This article reports employee cross training as a significant motivational practice to retain employees, compared to other motivational factors like performance based reward, functioning situation, guidance, perks and perquisites. For this reason a survey was conducted on 100 executives and managers from 20 different companies. The results exposed that cross training significantly prevents turnover.

Abstract: The nurses’ self-concept can be defined as information and beliefs that nurse have about their roles, values, and behavior which help individuals function at a higher level and use their learning experiences optimally. This study aimed to determine the effect of professional self-concept teaching on clinical performance perception of senior nursing students. A preliminary study was conducted to confirm the validity and reliability of the nurse self-concept questionnaire (NSCQ) and 6-dimension scale of nurse performance (6-DSNP). The participants consisted of 72 senior nursing students, sixty of whom agreed to participate in the study and complete the questionnaires. Then, the students were randomly categorized into case (n=24) and control (n=36) groups. The case group participated in the professional self-concept workshops for two days. Immediately (T2) and three months after the intervention (T3), the questionnaires were filled by both groups. The 6-DSNP score of the participants attending the workshop was significantly higher than that of the subjects in the control group (p<0.0001). Therefore, professional self-concept teaching can significantly affect the clinical performance of nursing students. Therefore, incorporating professional self-concept teaching into the nursing program can be effective for their clinical performance, and help nursing students have positive attitudes towards their competencies.

Abstract: After the establishment of modern style schools and colleges in Iran in the late nineteenth and early twentieth century, the need for trained and qualified teachers became the concerns of the authorities then. Some professors and teachers from Europe were the first pioneers who came and trained some teachers based on those days’ standards. Since then, there have been a lot of changes in the curriculum and the syllabus designs of the academic teaching generally and English teaching specifically. Teaching English academically in Iran has had so many ups and downs during the last three decades. Unfortunately, the outcomes of these alternations do not show hopeful horizons to the usage of English language fruitfully.

Abstract: The increase in shareholders' wealth from the leverage of debts is an important principle that forces the managers of the companies to pay enough attention to the time of the financing. Financial experts look for an optimized combination of the capital to maximize the company's value and consequently, to maximize the shareholders' wealth. In this regard, they have considered the effects of tax-savings from interests of debts and the low rate of debts costs in comparison to other capital resources. Some theories have been proposed in this regard that mainly focus on the positive effects of usingleverage of debts in increasing the shareholders' wealth. This research intends to investigate the effects if financing on the equity turnover of the active companies in Tehran Stock Exchange. In this regard, the companies who have used loans or capital increase as a financing way in a 5-year interval have been selected. The effects of two mentioned financing methods (loans and capital increase) on the ratio of their equity turnover have been tested on the basis of their financial reports. The results show that the ratio of total assets to the equity (leverage intent) is significant among the group of companies that have received debts and the group of companies that have increased their capital; but the ratio of equity turnover and the ratio of total assets, and the ratio of net profit to sales is not significant among the two groups of the companies. In other words, getting the loan by the active companies in Tehran Stock Exchange has not led to create a desirable financial leverage.

Abstract: Panax ginseng is one of the most important medicinal plants in Asia, particularly Korea. Triterpene saponins (ginsenosides) are the main bioactive compounds in P. ginseng. The present study investigates the growth characteristics and variation of ginsenoside content in the leaves and roots of Korean ginseng (Panax ginseng) at different growth stages (from 1 to 6 years). Variation in ginsenoside content of both the leaves and roots was higher at the beginning of growth (1-3 years) and then increased with decreasing rates. Root fresh weight increased by 3.3, 5.0, 2.2, 3.0, and 1.7 times for successive year intervals. In comparison, leaf fresh weight increased by 4.6, 2.6, 3.7, 2.4, and 1.2 times for successive year intervals. Analysis of Korean ginseng leaves and roots indicated the presence of 10 ginsenosides (Rb1, Rb2, Rb3, Rc, Rd, Re, Rf, Rg1, Rg2, and Rh1) with the leaves containing higher levels of ginsenoside than the roots. All ginsenosides were maximally accumulated in the leaves during the early growth stages(1st and 2nd years), whereas maximum accumulation was recorded in the roots during the later growth stages (~5 years) Levels of ginsenoside Re, Rd, Rg1 and Rc were higher in the leaves than other ginsenosides at all growth stages. Rb1, Rc, and Rb2 ginsenosides levels exhibited wide variation in the leaves across each year  interval compared to the other 7 ginsenosides. Rb1 accumulated more in the roots than in the leaves of Korean ginseng. Of the 10 ginsenosides examined, Rf ginsenoside content in the roots exhibited wide annual variation, with a difference of 3.3 times between the highest and lowest content. Overall, ginsenosides levels were much higher in the leaves compared to the roots, with plant age also contributing to variation in the levels of ginsenoside compounds.

Abstract: The caper bush (Capparis spinosa L., Cappari daceae) has been introduced as a specialized culture in some European countries during the last four decades. The economic importance of caper plant (young flower buds, known as capers, are greatly favored for seasoning and different parts of the plant are used in the manufacture of medicines and cosmetics) led to a significant increase in both the area under cultivation and production levels during the late 1980s. The main production areas are in harsh environments found in Morocco, the southeastern Iberian Peninsula, Turkey, and the Italian islands of Pantelleria and Salina. This species has developed special mechanisms in order to survive in the Mediterranean conditions, and introduction in semiarid lands may help to prevent the disruption of the equilibrium of those fragile ecosystems.

Abstract:During the last years, organizational performance of manufacturing organizations is considered to be a key for a country’s economy. As a result of high positive performance of manufacturing organization; the overall effects on the society have attributed the attention and the interest of organisational researchers. Armstrong and Baron (2003) highlighted the need of performance management as being strategic, integral (vertical, functional, human resource integration and integration of individual needs), focus on performance improvement as well as with the development. Gates and Otley (1999) further broaden the scope of performance measurement to include strategy development and the taking of action. In this study, researcher investigates the extent to which an organizational performance is affected by the actions of manufacturing leaders than by just implementing strong rules and regulations in the manufacturing organization. It was also examine whether differences in manufacturing organizational performance and actions of their leaders relate directly to manufacturing organizational performance or vice versa. There are number of tools and techniques available to measure organizational performance e.g. balance score card theory (BSC) by Kaplan and Norton (1992) based on stakeholder theory. The balanced scorecard approach was used as an operational tool, and it is employed to measure and improve operational performance of manufacturing organizations. According to Professor, Bob Kaplan, balance scorecard approach has further extended the measurement of organizational performance. Lipe and Salterio’s (2000) observed that the application of balance scorecard approach facilitates managers’ judgment, they further elaborate that balance scorecard approach improves managers’ judgement regarding what is actually essential without any overloading of information. Further according to Tomasello M et al (2005), humans are more skilled than other animals at discerning what others are perceiving, intending, desiring, knowing, and believing—allowing group decision based on mutual discussion. It is therefore expected that the performance of the manufacturing organizations in this study to be attributed to the ability to actually do the job of their subordinates by the manufacturing leaders and thus set an example for the workers and thus enhance the performance of the manufacturing organization. Based on the results of data analysis of 132 manufacturing organization leaders/workers, it was found that organizational performance measured using balance score card approach is negatively related to both strong rules and regulations than by the actions of manufacturing organization leaders. Researcher argues this is due to strong rules and regulations in manufacturing organizations and so subordinates own innovativity reduces and causes organisational performance at stack. On the other hand manufacturing leaders’ positive attitude has a significant positive relation between manufacturing organisational performance. Finally, it was also observed that manufacturing leaders educational background, related field experience positively influences the manufacturing organizational performance. Overall, results suggest that the more skilled and experience a manufacturing leader has, the more positive is the organizational performance. In a nut shell it can be concluded that manufacturing organizational performance is directly related to the actions of manufacturing leaders as well as the skills, experience and ability to do the job of his/her subordinate. A model for improving performance of manufacturing organizations has been developed as a result of data analysis of this study and is presented in this paper to enhance the performance of manufacturing organizations.

Abstract: Omar Khayyam (1047-1123) was born in the Seljuk period, one of the greatest eras of Iranian history in terms of the profusion of towering figures in different branches of learning. He was the man who, in collaboration with other astronomers, succeeded to devise the Jalalian calendar in the region of Malikshah (1073-1092), an enormous achievement indeed. Khayyam, in his Quatrains, challenged religious doctrines, alluded to the hypocrisy of the clergy, cast doubt on almost every facet of religious belief and appeared to have advocated a type of humanism.The draft sybaritic image of Khayyam after translation of Fitzgerald in the West that has led established pubs and wine called Omar Khayyam, often based on hedonistic approach of Rubaiyat For finding the effect of quatrain of Khayyam in the Europe, it needed to define some philosophical terms as Epicurism, Hedonism and materialism, then study the philosophical approaches of these quatrains in the west and analyzed them according of political and social situation of that era. This research, by referring to some methods of criticism, based on written historical events and the phenomenological model, tried to present the new theoretical point of view of relatively realistic message of Khayyam in the world.

General Overview on Educational Institutions in Islamic Civilization

Abstract: The scientific condition of the Arabian Peninsula before Islam and even at the beginning of Islam was so disappointing that the number of literate people did not exceed 16 0r 17 at the time of Muhammad. Then the first sparks of learning and literacy started with the Quran messages. In this way Quran verses and the Prophet’s tradition became the best guides and sources of inspiration for learning and literacy. This book from the one hand encouraged people to think and respect knowledge and make distinction between those who are literate and those who are illiterate (1), and on the other hand, broaden their view point toward learning and made them seek knowledge; since the first Ayah (verse) of Quran started with the words “read in the name of God who created you.” (2) It shows that the first steps of learning starts with reading; and knowledge changes the darkness of ignorance to the light of recognition and reading opens the gate of wisdom. Prophet Muhammad with the emphases on learning and literacy encouraged Muslims toward learning and increasing their knowledge and understanding. Because preserving the Suras (chapters) of Quran was very important to him, he had an especial concern over oral and written learning of these Suras among his followers in the mosque. Apart from its religious entity, mosque became an important place for learning and education and Muhammad is considered as the first teacher of Islamic society. (3) In addition to the encouragement found in holy Suras for literacy, establishment of the schools and universities which were done by Imams, created a kind of jubilee among Muslims in the history of Islam and made the act of establishing schools as important and valuable as making a mosque. For this reason after a short time several schools, Maktabs, and mosques opened in Islamic nations. And these schools had a considerable role in the progress and growth of Islamic civilization and helped Muslims come to the pick of their civilization in the first few centuries.

Abstract: Nonnegative Matrix Factorization (NMF) based methods have found use in the context of blind source separation, semi-supervised, and unsupervised learning. These techniques require the use of a suitable cost function to determine the optimal factorization, and most work has focused on the use of least square formulation which is prone to large noise and outliers. In this paper we developed robust NMF algorithm using -norm which exhibit stability and robustness w.r.t. large noises. This algorithm is as efficient as the algorithms for least square formulations, avoiding the significant computational complexities routinely associated with -norm formulations. The experimental show that -NMF can effectively separate the observed that contain outliers better than standard NMF.

Abstract: Due to high temperatures and pressures in the thrust chamber, regenerative cooling along with film cooling is one of the basic requirements for safe operation. This is ensured by controlling the rate of heat transfer from the walls of chamber through the coolant flow rate. For optimum performance of thrust chamber using efficient combustion, specific heat transfer rates through the nozzle section are required to guarantee the structure integrity of the chamber. Analytical procedures for the thermal design of thrust chambers are fairly limited and designers have to rely on  empirical  relationships  and/or  computational  methods  to  calculate  the  heat  transfer  rates. Experimental  correlations  are  usually  used  to  predict  heat  transfer  through  the  internal  wall however the exact mechanism of heat transfer is not fully understood. Here a comparison of analytical and empirical approaches has been made for a simplified geometry consisting of two concentric shells. The simplified geometry allows direct application of analytical approach and provides a test ground for the empirical approaches. Results for heat flux and hot side wall temperatures are also compared with a coupled numerical simulation using commercial software Fluent. While estimations for cooling fluid outlet temperature and temperature of outer wall of coolant shell are also compared with the experimental data. The comparison indicates that the analytical  method  for  the  heat  transfer  calculation  matches  the  numerical  simulations  and experimental data reasonably well.

Abstract:In this research we study the effect of accounting data behavior according to the business cycles in Tehran stock exchange. More over this research examines the behavior of accounting data according to the business cycles, by considering the special features of companies. The studied accounting data in clouded sales growth, gross profit margin changes, changes in profit before tax and net profit and total assets changes. The results of this research show that in Tehran stock exchange there are significant relationships between some of the accounting variables (sales growth and gross profit margin) with business cycles and no relationship is seen among some of the variables (such as total assets changes). Moreover this research's findings indicate that the relation between the accounting data and business cycles is affected by the size of company and cyclical or non-cyclical nature of company (special features of companies).

Abstract: Lead poisoning is a serious condition caused by increased levels of the heavy metal lead in the body. Lead interferes with a variety of body processes and is toxic to many organs and tissues including the heart, bones, intestines, kidneys, liver as well as reproductive and nervous systems. The present study aimed to evaluate the amleiorative effect of bee honey against lead acetate toxicity. Honey was administered orally at doses of 0.2, 0.4 and 0.4 g/kg for one month. Lead treatment (200mg/kg, p.o) started 10 days before the honey treatment and continoued with honey for one month. Positive control group were treated with lead acetate for 40 days. Lead intoxication caused a significant increase in serum malondialdehyde (MDA), decreased glutathione (GSH), increased uric acid, urea and creatinine. Moreover, lead administration increased bilirubin and the enzymatic activiry of GOT, GPT and alkaline phosphatase. In addition, lead intoxication increased total cholesterol, HDL, LDL and triglycerides. Bee honey dose- dependently reversed the adverse effect of lead on liver and kidney function and decreased MDA level and noormalized GSH level. In conclusion, induction of oxidative stress and disturbing lipid metabolism may be responsible for the adverse cellular effects of lead and that these cellular events may mediate the hepatotoxic and nephrotoxic manifestations in lead intoxication. Also, the beneficial effect of honey is likely- partially- due to its antioxidant property and its modulatory effect on the metabolic processes.

Abstract: Indonesia is characterized by an uneven population distribution, i.e., approximately 60 percent of the population is concentrated on Java Island (7 percent of Indonesia’s land areas), and others live on the islands of Kalimantan, Sumatra, Sulawesi and Papua. In order to mitigate the overpopulation problem in Java, the Indonesian government created a transmigration program (transmigrasi) in the early 20th century to move people from densely populated areas (mainly Java) to more sparse areas. The Lampung Province in Sumatra has been one well-known destination of transmigration since the first migration in 1905. Focusing on the fishermen that migrated into the coastal area of Lampung Timur in the mid-1980s, this study aims described the transmigration-induced changes in their socioeconomic status (SES), community health, environmental conditions and quality of life. Focus group discussion with selected people and interviews with 179 heads of households (all are first generation) revealed that their SES and community health conditions generally improved after transmigration. However, certain kinds of environmental degradations happened after they settled in the area. In 1996 some people moved out to the elephant-conservation area to seek for more fish, but they were forced to come back to the transmigration area after having social conflicts with the government. The perception of community health and environmental conditions, and QOL score with social conflict experience was worse than without social conflict experience, and the desire for further migration was higher in the former.[Nugroho, AS., Fujimura, M., Inaoka, T.

Abstract: This paper is about minimizing intercellular movements of parts for the formation of manufacturing cells using GA approach. GA is a search technique based on the process of biological evolution and has been applied as an optimization method for the formation of manufacturing cells. Different GA operators and their importance in the optimization of cellular manufacturing have been discussed. A MAT LAB code has been developed for the calculation of different matrices and fitness values of chromosomes.  The initial population of possible solutions (chromosomes) is generated randomly and the fitness value of each chromosome is calculated using code developed for the purpose. The next population is generated by the application of genetic operators process is repeated till stopping criteria is satisfied. Total ten populations are generated by the GA procedure and fitness values of different generations have compared graphically with detailed analysis. It is evident that using GA has minimized the intercellular movements of parts which indirectly improves productivity, profitability and provide competitive edge to the manufacturing enterprise in global environment.

Abstract: Background: No consensus exists regarding the optimal treatment of ipsilateral femoral neck and shaft fractures. We report our experience of managing 13 patients with ipsilateral femoral neck and shaft fractures by using either cannulated screws or dynamic hip screws for the neck and retrograde femoral nail for the shaft. The purpose of this study is to evaluate the function; outcome and healing of that complicated fractures. Material and methods: A consent was taken from thirteen patients who sustained ipsilateral femoral shaft and neck fractures from January 2007 and March 2011 in El Minoufiya University Hospital in Egypt. 10 patients with fracture neck femur had been treated with cannulated screws while 3 patients were treated by dynamic hip screw. all fractures shaft had been treated with retrograde femoral nail.. The mean follow up period was 18 months with range from 12-36 months. Results: There were 10 males and 3 females. The average age was 31 years old with range of 19-45years. The mean follow up period was 18 months with range from 12-36 months. The average healing period of femoral neck fracture was 14 weeks and all femoral neck fractures united. Average union time for femoral shaft fractures was 19 weeks (range, 16–36 weeks). Three femoral shaft fractures needed bone graft at six months. Conclusions: The treatment methods used in the present study achieved satisfactory functional outcome in these complex fractures. The femoral neck fracture should preferably be stabilized first.

Abstract: Obesity is a major global epidemic problem. Obesity results from the combined effects of genes, environment, lifestyle and the interactions of these factors. The leptin receptor gene plays a critical role in the regulation of body weight. Genetic variations of leptin receptor gene may play a role in the pathophysiology of human obesity. In this study, the association between the LepR gene polymorphism and obesity in Jeddah population was evaluated by determine the distribution of alleles frequency of the leptin receptor GLN223ARG polymorphism in 180 volunteers (94 males & 86 females). Each gender was divided into 2 groups: Children and Teenager (6-17 years old), and Adults (18-27 years old). As well as each group were divided into 2 sub-groups according to BMI obese and non obese (control). When comparison the obese and non obese groups, results demonstrated that no significant difference between genotype distribution and body mass index (BMI), weight, hip, waist and waist-hip ratio (WHR). In contrast, there was a significant increase in GG genotype (OR= 19.11, 95%CI: 0.95-384.95, P= 0.01) compared to AA genotype, and GG genotype (OR= 25.24, 95%CI: 1.25-509.46, P= 0.006) compared to AG genotype in males children and teenagers, which suggests that genetic polymorphisms (GLN223ARG) of leptin receptor gene may play a role in prevalence of obesity in children and teenagers males group.

Abstract: Patients with prosthetic heart valve are in need of anticoagulant therapy for protection against thromboembolic events. Warfarin therapy is monitored by Prothrombin time (PT) and International Normalized Ratio (INR). The clotting assays are invasive and may carry infection and prosthetic valve endocarditis. We try to use human saliva as noninvasive diagnostic fluid to access anticoagulant state. Our study was done in Cardiothoracic Department in Ain Shams University Hospital on 132 Patients had prosthetic valve (MVR, AVR or DVR) and under Warfarin therapy. We measure salivary TF activity by Quick one stage method; then calculate TF activity ratio and TF activity log to 10. The therapeutic value of salivary TF ratio ranges from (2.23 to 3.60) and salivary TF log to 10 ranges from (2.364 to 2.560). There is strong positive correlation between both salivary TF ratio and salivary TF log to 10 with INR (2.00 to 3.50). Salivary TF activity ratio has wider range than TF log to 10, and needs each laboratory to make its control under standardized conditions. Thus, the measurement of salivary TF activity ratio is a reliable test for follow up of patients on oral anticoagulant therapy.

Abstract: This paper is based on a quasi-experimental study which investigated the impact of Shared-book Reading (SBR) on the development of vocabulary and oral narrative skills of young Indigenous Malaysian children learning Malay as a second language. Sixty three (63) Orang Asli children from two first-grade classrooms participated in the study. One of the classes was randomly assigned to implement SBR sessions while the other served as wait-listed control.  Prior to the intervention, all students were assessed on a grade-appropriate literacy screening test (LINUS I), a Rapid-automatized naming task (RAN), and a Children’s Nonword Repetition Test (CNRep). After a five-week intervention, all students were assessed on vocabulary and storytelling. Results showed that experiences of SBR accelerated Orang Asli children’s oral Malay language production and increased their level of word-meaning knowledge. Specifically, the SBR group performed significantly better than the control group on the word-defining task. They also produced more coherent, higher quality narratives in a wordless picture story-telling task. They told the stories with greater verbal rate which contained significantly greater vocabulary diversity. These results altogether yield significant implications for the literacy instruction practices of Orang Asli children.

Abstract: Heavy metals pollution has become one of the most serious problems today and the use of plant biomass for the detoxification of industrial effluents for environmental protection and recovery of valuable metals offers a potential alternative to existing treatment technologies . Considering the fact that Cyperus laevigatus is resistant to polluted environmental and has the capability to accumulate heavy metals in its body, plant biomass itself can also be used to remove heavy metals from contaminated water by harnessing its natural properties. In this research the experimental design technique was used to optimize the biosorption of cadmium and lead ions by Cyperus laevigatus biomass from aqueous solutions, simulating industrial effluents. The removal of Cd+2 and Pb+2 was studied, separately, using the factorial design 23. The three factors screen were pH , temperature (T) and metal ion concentration (X) at two markedly different levels : pH (2.0 and 6.0) T (20 and 45 0C ) and X (20 and 800 mg l-1) . The most significant effect for   Cd+2 and Pb+2 biosorption was ascribed to T . The interaction effect of X. pH and T.X also have a significant influence on the Pb+2 efficiency. A normal distribution was observed between the predicted values (model) and the observed (experimental).

Abstract: Goal and Purposes: Iranian older women population is growing and becoming older due to fertility decline and also success of health programs resulting in increases in life expectancy. As in the last two decades the population of elderly women increased from 3% to 4.1% and to 7 percent in recent census. It is expected that over the future decades this increasing trend continues due to the increasing number of elderly women worldwide and markedly increasing of life expectancy of women after 50 years, it is expected that women represent a larger number and proportion of Iran older people population. However, surprisingly, the statistics show that in 1976 to 2005 the population of the elderly women has declined in each decade. This situation occurred while life expectancy in men is usually less than women. Therefore in this paper we try to review the situation of Iranian elderly women in the Iranian population in terms of the elderly woman's health, education, family status, employment, quality of life, social isolation. Methods: This study is a review study that have been made with the views of experts by interview with experts, expert panel, group discussions and also extracting information from relevant books, and articles. Finally, the results were analyzed. Results: Considering the status of elderly women from various dimensions, including physical health, psychological, familial and social we find out that Iranian elderly women are not only vulnerable groups in term of their gender but also are in risk of different problems in elder years. This causes that this group threat double way in terms of quantity and quality of life. In this article we are going to evaluate Iranian older women from different dimensions aimed to attract focus of the politicians and decision makers to the elderly, especially elderly women. Future high quality national studies are required to be conducted in Iran to investigate physical, psychological and social aspects of Iranian older women.

Abstract: We developed an efficient protocol for in vitro shoot organogenesis and plant regeneration from Cymbalaria muralis leaf explant cultures. Leaf explants were cultured in media containing different concentrations of cytokinins. After determining the most effective cytokinin and cytokinin concentration, we tested the effects of various auxins at different concentrations on the regeneration efficiency and growth of shoots from excised leaf segments. Among the cytokinins tested, zeatin supplementation resulted in the highest shoot initiation efficiency, largest number of shoots per explant, and longest shoots after 6 weeks of culture. In this study, zeatin in combination with an auxin, naphthalene acetic acid, was highly effective for inducing shoot regeneration. Among the cytokinin/auxin combinations tested, supplementation of the culture medium with 1 mg/L zeatin and 0.1 mg/L naphthalene acetic acid resulted in the greatest number of shoots per explant (8.3), highest regeneration efficiency (93%), and longest shoot length (27 mm). Zeatin with 0.5 mg/L naphthalene acetic acid supplementation resulted in the second-highest values for each of these measures. The combined application of cytokinin and auxin might play a vital role in shoot organogenesis of C. muralis.

Abstract: For the regeneration of shoots, leaf segments of Rehmannia elata were cultured on Murashige and Skoog (MS) medium supplemented with various concentrations of 6-benzylaminopurine (BAP) (1, 2, or 4 mg L-1) with or without 1-naphthalene acetic acid (NAA) used at 0.1 or 0.5 mg L-1. Regenerated shoots were obtained from the leaf cultures at all BAP concentrations with or without both concentrations of NAA. However, the highest shoot regeneration frequency (92.23%) and shoot number per explant (4.03 shoots) were obtained on MS medium supplemented with BAP (4 mg L-1) and NAA (0.1 mg L-1) solidified with Gelrite (4 g L-1). The survival rate was ~70% when the rooted plants were hardened and transferred to soil. The continuous production of R. elata-regenerated plants from leaf explants under these conditions could be used as a possible micropropagation system for this species.

Abstract: This paper presents how the TOPSIS method is used in ranking the training methods that are used for sustainable agriculture. Sustainable agriculture is the adoption of eco friendly methods of agriculture that will aid in preserving the environment for future generations. This research is looking into how effective the factors of training for sustainable agriculture are in promoting it. The objective of this research is to find out which method is factor is more effective when it comes to the driving factor of the training on sustainable agriculture. Since this is a problem with multi decisions for the solution, the TOPSIS method is the best to use as it supports the evaluation of multi decision criteria. The TOPSIS method will be used side by side with the AHP method, this is because the weights of criteria will be gotten using the AHP method. The research will give both the qualitative and quantitative aspects of the research. The most important part of the assessment is to understand the TOPSIS method and criteria in order to analyze the effectiveness of the training that sustainable agriculture uses. The finding of the research was that the most effective factor that influences the training of sustainable agriculture is increase in crop yield. This is because the increase in crop yield will automatically lead to the other factors; for example, increase in crop yield will lead to improved economic status of the region and its people. The conclusion of the research is based on the most effective factor and the benefits it gives to the regions that decide to adopt sustainable agriculture.

Abstract: The use of aluminum alloys are of significant use in industry. Studying of design parameters of such products is important as not much work has been done for optimizing it. The generic formulation involves the flow, velocity, continuity fluid dynamics and shape related issues. The time for filling the mould and shape factor also play major role in performance of the casting process. In this paper, a simple shape is chosen, designed and mould is finalized. From casting and then design experiments with the stated parameters, an optimized design values have been obtained. The effects of each design parameter aid us to identify and prioritize them for improvement of the process. This give first rough cut estimate of the variables in sand casting process.

Abstract: Osteoporosis is a common medical condition affecting over 5% of the population. It affects all bones, including those of the facial skeleton, which in turn might have an effect on facial dimensions and indices. We examined 196 healthy volunteer adults and 155 osteoporotic patients. Three longitudinal, transverse and diagonal measurements were taken and three indices were estimated. Osteoporosis was found to increased most of the dimensions in male and female patients. However, it decreases some parameters and indices that include upper facial length, total facial length, nasal width, upper facial index and prospective index. We also found that some of the studied parameters significantly changed in one gender, but did not change in the other. The parameters used in this study can be used as indicators of the effect of osteoporosis on facial dimensions. However, more studies are required to confirm the current findings considering the duration of the disease and the effect of treatment.

Abstract: Nursing students` clinical evaluation is an important subject in nursing clinical education. Some studies mentioned issues in nursing students` clinical evaluation that manifest in students` complaints and frequent meetings between students and instructors to discuss some problems in this area. Despite some efforts, this subject is still a major challenge for all people involved.  So we need to know much more about it, especially from the view of nursing students because they are the one who are evaluated and are at the center of the experience. The aim of this study is determining nursing students` experiences and perspective about their clinical evaluation. This is a descriptive qualitative study. Participants were selected in nursing and midwifery schools of 3 medical Universities, involving baccalaureate nursing students in 3rd and 4th year of nursing education. Sampling method was purposive and was continued to the point of data saturation. Totally 40 students participated in 6 focus groups. Content analysis was applied to analyze the data. During analysis 4 themes and 10 subthemes were emerged including evaluators` issues (professional characteristics of educator, self-evaluation, clinical nurses), evaluation necessities (tool proficiency, practical evaluation), evaluation process (goal-oriented evaluation, evaluation time and type) and emotional environment of evaluation (relationship, confidence).  Results showed many challenges nursing students confronted in clinical evaluation. They said they have issues with people participated in evaluation and their way of participation, strategies and methods used in evaluation, clinical evaluation planning and emotional environment in evaluation; which influence their clinical evaluation. It seems; considering the mentioned issues, clinical evaluation process needs an overall revise in order to correctly assess students` progress toward clinical learning objectives so facilitate the development of students into safe, ethical and accountable practitioners.

Abstract: As the world population is getting older, health care for elderly becomes important. Distribution of specialties related to elderly health care is highly variable. To assess the distribution of specialties related to elderly and the aged population (i.e. over 65 yrs.) a prospective analytical study was designed from 1999-2009. During this 10 year period ageing process was increasing, initially slow but rapid in the last years. Internists, cardiologists, neuro-psychiatrics, and neurologists in the beginning of period had an increasing trend and declined in the mid-period then had decreasing trends. Orthopedic surgeons were almost increasing in all of the decade. In present, the number of geriatricians are fewer than 10 in the whole country, and health policy should move toward health care providing for elderly. Keeping in mind that aging process is increasing recently, number of specialists and physicians caring for elderly should also increase. (abstract: truncated at: 144 words).

Abstract: Parkinson's disease (PD) is a progressive disabling neurodegenerative disorder characterized by severe difficulties with body motions and associated with autonomic dysfunction, depression, and dementia. Oxidative stress is thought to play an important role in the pathogenesis of PD and oxidative damage characterizes proteins, lipids, and DNA in the substantia nigra pars compacta (SNc) of PD patients. To date, L-dopa is the most effective medication for controlling PD symptoms, although long-term treatment can enhance oxidative stress and accelerate the degenerative process of residual cells. Thus, the inhibition of oxidation of L-dopa and the inhibition of reactive oxygen species formation are important strategies for neuro-protective therapy. Therefore, efforts are made not only to improve the effect of L-dopa treatment for PD, but also to investigate new drugs with both antioxidant and neuro-protective effects. Hespiridin (HDN), a naturally occurring flavonoid presents in fruits and vegetables, has been reported to exert a wide range of pharmacological effects including antioxidant, anti-hypercholesterolemic, anti-hyperglycemic, anti-inflammatory, anti-carcinogenic and neuro-protective actions. Chlorpyrifos (CPF) was used in this study as an animal model of PD. Model of CPF-induced Parkinsonism in rats produced neurotoxicity, oxidative stress, hyper-lipidemia, hyperglycemia and DNA damage. Seventy male rats were used in this study and divided into seven equal groups. After 6 weeks, the following groups were studied, control group, CPF group, HDN group, Sinemet group, CPF+HDN group, CPF+Sinemet group, and CPF+HDN+Sinemet group. Here in the present study, the treatment of parkinsonism with HDN alone or combined with sinemet provided a neuroprotection effect when given early in the course of the disease. In conclusion, HDN could be recommended as a disease-modifying therapy when given alone or mixed with L-dopa in course of Parkinson’s disease.

Abstract: MRP is a plan for the production and purchase of the components used in making items in the master production schedule. It shows the quantities needed and when manufacturing intends to make or use them.MRP is a commonly accepted approach for replenishment planning in major companies (Gharakhani et al., 2011). Implementation of any production system requires that all of the factors identified in its implementation and also determine the importance of each. In this study the researcher to identify and prioritize the Effective Factors in MRP implementation. The survey results show that the most important Effective Factors in MRP implementation are Top management support and Formal project planning. Moreover, the less important factor is software / hardware Characteristics.

Abstract:  Policy analysis is determining which of various alternative policies will most achieve a given set of goals in light of the relations between the policies and the goals. For an organization or any institution it is vital to determine which on strategies, plans or policies are better performed than others and finally policy makers can make better decisions towards organizational objectives or vision. The main purpose of this applied research is to investigate the critical success factors of policy analysis in the financial sector of Iran. To achieve this purpose, after detailed review of literature by using a questionnaire essential critical success factors of policy analysis in the financial sector have been identified and presented. Indeed, Critical success factors (CSFs) have been used significantly to present or identify a few key factors that organisations should focus on to be successful. Required data has been gathered by using viewpoints of study’s experts. Basic tool for data analysis are SPSS18.0. Results of this study can be very useful both in theoretical and applied viewpoints especially based on the research conceptual framework.

Abstract: In this study, the structure, and surface morphology of dentin after ablation with ultra-short pulses (USPL) were evaluated using environmental scanning electron microscopy (ESEM) with EDAX analysis and scanning electron microscope micrographs. The dentin specimens examined were irradiated by (100, 300 and 400 mJ) of ultra short pulse laser . Based on EDAX results, it was possible to identify the suitable energy density as the ablation threshold for dentin. The results demonstrate that by selecting suitable parameters one can obtain efficient dentin surface preparation without evidence of structural changes and thermal damage, i.e., with minimized heat affected zones and reduced collateral damage, which characterized by formation of microcracks , grain growth and recrystallization in the heat affected zones.

Abstract: There are different achievements about the Electromagnetic waves interaction with acetylcholine and the resultant studies on the Alzheimer patients. Because the acetylcholine intermediate enzyme is reduced in the brain of these patients, based upon some research works it is believed that the absorption of electromagnetic field in acetylcholine may tend to   increased this enzyme amounts in the brain of these patients, then in this research we studied the excitation and the radiation absorption process effects of the extremely low frequency (ELF) electromagnetic waves in the acetylcholine from this magnetic field. The absorption process calculated with the aid of IR (Infra Red), UV (Ultra violet), and the Visible spectroscope devices.

Abstract: The Fuzzy logic method offers superior log estimation properties for a large class of well log functions and has been employed as a standard tool in formation evaluation of Oil production zones. However it suffers from spurious behavior in the vicinity of edge trends in log signals. In this article, we used The MULTI-RESOLUTION GRAPH-BASED CLUSTERIN (MRGC) Supervised framework for obtaining lithology properties from PEF & LITH logs that estimated in one of the Well (D) in the field since there is no core data in most wells. Estimations are performed from basic information and model logs of another well (A), including RHOB, NPHI, DT, PHIE, and NDS. Taking advantage of this framework, we show that it is feasible to recover log data from a relatively accurate method especially in inhomogeneous formation than the Fuzzy logic method.

Abstract: Online shopping is a new phenomenon in the field of E-Business and is certainly going to be the future of shopping in the world. Though online shopping is very common outside Malaysia, its growth in Malaysian Market, which is a large and strategic consumer market, is still not in line with the global market. The present research paper has used exploratory study to highlight the various factors and variables impacting the behavior of consumers towards on-line shopping in Malaysia. Data was collected from students’ samples in Malaysia. SEM (Structural Equation Model) was used to test the hypotheses and confirmed the fit of the model. The researcher found that there are three factors for explaining attitude and intention towards online shopping, which are privacy, security and subjective norm. The results show that if students worry about whether their information due to the process of online shopping will be used for other purposes, it will reduce their purchase attitude.

Abstract: The language to control objects is a primary requirement in design of a complex system. Context free grammar plays an important role in modeling control functionalities of a system by grammatical rules. This generates naturally the operation of a system by the language which having commands in the form of strings generated by variables which are nested inside variables arbitrarily deeply. The formal method Z is an ideal notation which is used for describing state space of a system and then defining operations over it. Consequently, an integration of context free grammar and Z will be an effective tool for increasing modeling power for a complex system. In this paper, we have given a procedure for integrating CFG and Z. Formal definition of a CFG is defined. Then derivation of a string and further development of formal language is formalized. The specification of this relationship is analyzed and validated using Z/EVES tool.
