Abstract: This study was carried out with the aim of using Saccostrea gigas for biological monitoring heavy metals (Cu and Pb) on the Khor- Musa. Samples of oysters and sediments were collected from the intertidal zone at five different stations in Jan 2011. Sediment and tissue samples were oven dried and acid digested. The metal contents of samples were analyzed using an atomic absorption spectrophotometer. The results showed that Cu and Pb concentrations in the sediment samples are as follows: 17.79 ±1.60 and 6.04 ± 0.95 μg.g-1dw respectively. The metals concentration in the soft tissues of oyster was determined as 518.5 ±16.36 and 9.58 ±1.14 μg.g-1dw for Cu and Pb respectively. Similarly, Cu and Pb concentrations in the shells were found to be at 1.94 ± 0.19 and 2.49 ± 0.51 μg.g-1dw respectively. A Significant correlation was found between Cu and Pb concentration in soft tissue and sediment samples. Similarly correlations between metals contents of sediments and hard tissues were found to be significant,suggesting that the soft tissue of S. gigas should be a useful tool for Cu and Pb monitoring in the study area.

Abstract: One of the best definitions of Corporate Social Responsibility is that a corporation along with its commercial success, maintains all ethical, social and personal values, environmental values and benefits of interest groups. In the other words, Social Responsibility includes corporate manager accountability for legal, social and environmental expectations of interest groups. Considering the relationship between the state and corporate social responsibility leads to that effective implementation of this system increases the level of corporate social responsibility Promoting corporate responsibility will improve interaction between company and community. By strengthening the corporate social responsibility, companies not only can benefit from today's profits, but also consolidate their success and positions in the future as well. The other direct advantages of promoting corporate social responsibility includes more access to financial resources resulted from good reputation, risk management and supervision of the affairs of the organization, customer loyalty and interest groups trust to the company.

Abstract: Background: Killer-cell Immunoglobulin-like Receptors (KIR) are the members of inhibitory and activating receptors expressed mainly on the natural killer cells. KIR genes family is polymorphic strongly and its genomic diversity results in gene content and allelic polymorphism. The aim of this study was to report the distribution of the KIR genes in the Lur population for the first time. Materials and Methods: In this study, 100 unrelated healthy Lur individuals were KIR typed by polymerase chain reaction-sequence specific primers genotyping assay. Finally, Lur KIR genes distribution was compared with other Iranian populations. Results: Twenty-two different genotypes were found in the Lur population. The most common non-framework genes were KIR2DP1 and KIR2DL1 with a frequency of 98% and KIR3DL1 and KIR2DS4 with a frequency of 96% in the Lur population. The most common observed KIR genotype (AA genotype) consisted of six inhibitory genes, one activating gene and two pseudogenes, was occurred with a frequency of 29% in the Lur population. Discussion: The results show that KIR genes distribution in the Lur population has similar features with other Iranian populations studied before, but it is still unique because of decrease or increase in some loci frequencies.

Abstract: Background: Natural killer (NK) cell allogeneic reaction, defined as lack of interaction between donor inhibitory killer cells immunoglobulin-like receptors (KIRs) and recipient human leukocyte antigen (HLA) class I molecules, missing KIR ligand, has been shown to affect T-cell depleted hematopoietic stem cell transplantation (HSCT) outcome. However, its influence on non-T-cell depleted setting is still unclear. In addition, the role of donor and recipient activating KIRs in transplant results needs to be more investigated. Materials and Methods: In this study, the impact of recipient and donor KIR and KIR ligand genotypes on HSCT outcome was evaluated in 40 transplants for acute myeloid leukemia (AML) and 38 transplants for acute lymphoblastic leukemia (ALL) in a non-T-cell depleted setting from HLA-identical sibling donor. As transplant endpoints, overall survival (OS), disease-free survival (DFS) and relapse were assessed in recipients in a five-year period. Results: Regarding 'missing KIR ligand' no impact was found on OS, DFS and relapse for AML and ALL recipients. In AML patients, however, presence of KIR2DS3 and/or KIR3DS1 in donor genotype was associated with a higher five-year OS (P=0.006) and DFS (P=0.021) in a univariate analysis. In these patients, multivariate analysis showed that transplantation using either KIR Bx genotype with KIR2DS3 and/or KIR3DS1 present in donor was related to a trend toward occurrence of cGVHD; although it did not reach to a significant level (P=0.092). Discussion: These findings may imply that 'missing KIR ligand' in recipient is of little importance in our matched non-T-cell depleted HSCT outcome. Whereas, presence of KIR2DS3 and/or KIR3DS1 in donor KIR genotype increases survival in AML patients.

Abstract: Background: Alopecia areata is a common cause of hair loss. It is an autoimmune disease with a genetic background, and is triggered by stimulating factors such as stress. In this research, the effects of stressful events in patients with alopecia areata were compared to the control group during the last three months prior to the onset of alopecia areata. Method: in this case-control study, 120 patients were studied. After precise examinations, they were divided into two groups of 60 individuals each, one group with alopecia areata and the other one without alopecia areata (control group). In these two groups the level of stress was assessed by stress questionnaire and then compared to each other. At the end, after data collection, the SPSS software, Chi- square test and T test were used to analyze the data. The significant level for interpreting the relationship between variables was 0.05. Results: There was a significant relationship between hair loss and stress, the severity of stress and stressful events among patients. Conclusion: Based on the results of this study and previous studies, we suggest that beside the evaluating endocrine disorders in patients with alopecia areata, they should also receive a consultation from psychologists or psychiatrists as part of the treatment to reduce the severity of the disease and manage stressful events. Also, further studies are recommended in this regard.

Abstract: This study compares the impact of some corporate governance characteristics on firm performance of 87 companies listed on Tehran Stock Exchange and 96 companies listed on Bursa Malaysia. The aim of this study is to investigate the relationship between; percentages of directors’ ownership, board size, percentages of non-executive directors, independency of chairman from CEO and performance of 183 companies in Iran and Malaysia between 2006 and 2010. Moreover, leverage ratio and firm size are used as control variables. This study is a practical research; the data is processed and analyzed by multiple regression models using E-views 7 software. The results show that except firm size which has a negative significant relationship with corporate performance, there is no significant association between corporate governance and firm’s performance in Iranian companies’. But for Malaysian companies, the percentages of directors’ ownership, CEO duality, firm size and leverage ratio have significant negative association with firm’s performance.

Abstract: The increasing role of knowledge in economy has led to the emergence of the idea of the knowledge-based economy. A knowledge-based economy is an economy which is based on the production, distribution, application and the use of knowledge. There are different definitions for the knowledge-based economy, some of which are as follows. In the knowledge-based economy, the state’s policies, in particular, the policies related to technologies, industry and education require more attention, and the role of economic firms, infrastructures, and creating motivation for investment and training and education is significant. In this respect, the state’s policies should be directed towards creating a cooperative context among the state, the industry and the university, such that this cooperation strengthens, improves and encourages new technologies into all economic sectors and different firms, and facilitates the development of informational infrastructures.

Abstract: Blue Ocean Strategy is a situation in which companies produce products or services that are different from others and at the same time, stand out of intense competition existing between competitors of the market. These strategies seek to explore the unknown market space and focus on non customers, rather than focusing on the market. Among this, with increasing competition and the recognition of the market dimensions for competitors, companies are moving toward implementation of Blue Ocean Strategy in which rather than focusing on competitions on present demand, it is recommended to explore and create new demand in the market. Therefore, in the present study we sought to examine the impact of blue ocean strategies on the market value of companies listed in the Stock Exchange Market. For this purpose, five hypotheses were formulated, literature and research implications were extracted using the library and for information gathering, questionnaires were used, to test the hypotheses, paired comparisons test was used. In this study, all calculations were performed using SPSS software. The results showed that all five strategies to create a non competitive market environment, making the competitiveness nonsense, create and capture new demand, breaking the substitution of value-cost, aligning the entire system of organization's activities to achieve differentiation and low cost, are effective on firm value.

Abstract: Stock market reacts differently for advertisements and news of companies. In some cases the reaction of investors is not logical and causes some abnormalities such as great increases or decreases in prices and as a result of it the creation of abnormal returns in capital market. Thus, investors react to the new news published in the market. In the present research, following the previous ones, we have studied the stock market reaction of firms accepted in Tehran Stock Exchange towards unexpected earning and the interactions among unexpected earnings and earnings management. The statistical society for the present research involves 120 firms accepted in Tehran Stock Exchange which were chosen by an omitting sampling method. The results of testing research hypotheses approved the positive effects of unexpected earnings and qualitative characteristic of earning on price stock of companies.

Abstract: The Childhood Trauma Questionnaire (CTQ) is a brief self-report questionnaire that retrospectively assesses childhood abuse experiences among adolescents and adults. The goal of this paper is to investigate validity, reliability and factor structure of the CTQ in an Iranian sample. The sample consists of 400 guidance school students that selected through multiple-steps random sampling from guidance schools in Tehran. All students were asked to complete Childhood Trauma Questionnaire and Norouzie’s child abuse questionnaire. To examine the reliability of the CTQ, methods of internal consistency (Cronbach’s alpha ), Split-Half and re were used. The coefficients, that obtained from these methods, respectively were 0.90, 0.75 and 0.94 showing that this scale had acceptable reliability. validity was assessed using concurrent validity, Exploratory Factor Analysis and correlation of subscales with each other and with the total scale. The results of factor analysis using varimax rotation showed four factors: 1. Emotional Abuse (EA), 2. Physical Abuse (PA), 3. Emotional Neglect (EN), 4. Physical Neglect (PN). Furthermore, the correlation of subscales with each other and correlation of the total score of CTQ and concurrent validity scales were significant and as expected. The findings of this study suggest that the CTQ is a reliable and valid measure of Childhood Trauma in Iranian guidance school students.

Abstract: In this study, the effect of infiltration and heat-hardened treatment and return on physical and mechanical properties of ferrous powder metallurgy products were studied. For this purpose and to prepare ferrous powder and copper powder samples, each powder mixture separately were prepared in a form of a cuboid with floating matrix under tension of 500 MPa dense and crude blocks of iron and copper. For conducting infiltration, a copper sample was placed on each iron sample and this inter-furnace set with reduction atmosphere was sintered in temperature of 1150oC during 30 minutes. A number of samples were austenitized at a temperature of 850 and 925oC for 10 minutes and then after quenching in oil for 2 h were returned at 250oC. Samples were under tensile, hardness measurement, dimensional changes, open porosity and density determination tests. Results show improvement of strength and hardness coincide with increased flexibility in infiltration. Also under the effect of heat treatment, strength and hardness are increased, but flexibility is reduced. Infiltration with copper and heat hardened treatment lead to dimensional changes as fluff in samples.

Abstract: No organization can survive without customer. The secret of organizations’ permanency is their customers. Customer satisfaction is a concept that is further paid attention in today’s business since satisfied customers are the main component of organizational success. If banks did not manage to satisfy their customers, they would not survive and prosper. Indeed, banking has to perceive customers needs and demands and satisfy them in competition with its rivals. In this study, library research, internet resources, and field research are employed to investigate customers’ views on the effective factors in customers satisfaction using improved Kano’s model. This study is an applied and descriptive-survey research from the viewpoints of purpose and information collecting method, respectively. Its statistical population is the customers of a private bank in Tehran and the number of analyzed statistical samples is 302 persons who were selected using stratified sampling method. The information collecting tool is questionnaire which a Cronbach’s Alpha coefficient of 0.832 confirmed its reliability. SPSS software was used to analyze the data collected by questionnaire. Based on the results, “providing customers with financial consultancy” and “withdrawal of money from current account by ATM card” have the highest priorities in the case of attractive requirements. In the case of performance requirements, “duration of waiting in line” and “friendly and intimate attitude of bank employees” have the highest priority. “Checking credit balance” and “getting bank statement via internet” also have the highest priorities in the case of basic requirements, while the highest priorities in indifference requirements case involve “broadcast of bank advertisements in media” and “reading advertisements in newspaper”. Some suggestions have also been made at the end of this paper to further improve bank’s customers satisfaction level.

Considering this fact, the present study aims to investigate the service quality offered by Daroupakhsh veterinary-drugs distribution company using SERVQUAL model. Daroupakhsh veterinary-drugs distribution company sells its products wholesale to retailers. Thus, the marketing and sales personnel of the products distributers, which are considered as customers of the company, are taken as the statistical population of the study. The variables are evaluated using a five-point Likert scale. The study assumptions are tested by one-sample and paired-samples t-tests. According to the results from paired-samples t-test, there is a significant difference between the expected quality and the perceived quality in the case of “Physical Facilities and Equipment”, “Reliability”, and “Assurance” aspects, while the difference in observed medians of “Responsiveness” and “Communion” aspects are not significant. In other words, the company has managed to satisfy customers expectations in these two aspects.

Abstract– This paper presents a geometric technique to support multiplayer online games on a peer-to-peer system. Assumption in this paper is based on the fact that players are more interested in their region of visibility and influence than in the other regions. We use a computational geometry technique – Voronoi Diagram – to partition the game space into regions. The players in a region communicate with other players through the coordinator of the region. The resulting system scales up with the number of players and is able to distribute region updates in a scalable manner. We also propose techniques for fault tolerance in the wake of node failures. We have simulated a simple game to prove the efficiency of this technique.

Abstract: The General Well-Being Schedule (GWB) is a brief, reliable, and valid instrument to assess psychological well-being. The goal of this paper was to investigate validity, reliability and factor structure of the GWB-18 in an Iranian student sample. The sample consisted of 434 students (242 girls, 192 boys) with average age of 20.38. These students were selected through multiple steps random sampling from Tehran, Shahid Beheshti, Tehran Gharb, Olom -o- Tahghighat and Elm-o-Farhang Universities. All students asked to complete General Well-Being Schedule, General Health Questionnaire, Depression Anxiety Stress Scales, Satisfaction With Life Scale and Negative and Positive Affect Scales. To examine the reliability of the GWB, method of internal consistency (Cronbach’s alpha) were used, and validity was assessed using concurrent validity and Exploratory and confirmatory factor analysis. The results of factor analysis using varimax rotation showed three factors: 1. psychological distress, 2. well-being and vitality, 3. general health. Results of confirmatory factor analysis confirmed this finding. Internal consistency of the scale was 0.85 showing that this scale had acceptable internal consistency. The correlation coefficient between of the GWB-18 subscale and concurrent validity scales were significant and in the expected direction. The results of this study suggest that the GWB is a reliable and valid measure of psychological well-being in Iranian university students.

Abstract: various regulations have always discussed the mixing ratio in concrete mixtures. This study investigates the durability and compressive strength of the concrete samples with water/cement ratios of 0.41 and 0.44 and different cement contents varying from 300 to 400 kg.m-3. Results showed that neither a constant water/cement ratio nor the reduction of cement content has an undesirable effect on compressive strength. Nonetheless, this even can enhance the concrete durability in some instances. Naturally, the decline of water/cement ratio affects the concrete efficiency but concrete slump can be kept at an acceptable level by addition of admixtures.

Abstract: Separation is one of the most important steps in a chemical process so that a major part of energyis used for separation, concentration and purification. Fro the same reason, considerable work has been done to improve traditional processes and develop the savings technologies in regarding energy usage. Because of complexity and high cost of current processes, membrane separation technology has been recently examined as a good alternative. Membrane distillation (MD) has been taken into consideration as a new membrane distillation process enables to separate particles as tiny and petite as 0.1-7nm This process functions in low temperature between 30-90ºC that needs little source of energy besides high economic benefit. In membrane distillation (MD) process a hydrophobic membrane is utilized in contact with an input food solution. The base is on vapor-liquid equilibrium. In this paper, while describing membrane distillation, the parameters influencing MD as well as the laboratory system used were studied.

Abstract: Nowadays, human resources are of fundamental importance to organizational success and also have a considerable effect on organizational efficiency. Therefore, it is important to investigate human resources performance in the case of organizational studies. In this study, the operational unit of Gilan Province Gas Company was selected to investigate its personnel efficiency. Two combinational models of Data Envelopment Analysis (DEA) and Artificial Neural Network (ANNs) were used for efficiency analysis and ranking. Firstly, the analysis results obtained from Neuro/DEA were compared to DEA results and then, a comparison was made between the trained networks models. Analysis results show that the training method of second model compared to the first one illustrates the potential ability of neural networks in pattern recognition, function estimation, and efficiency prediction. Furthermore, it can be used to evaluate the organizations with fewer decision making units. On this basis, this study suggests the combinational model of Neuro/DEA 2 as the dominant model.

Abstract: Background and Aim of the study: coagulants have been being used for long to treat surface water and reduction of their use can bring about great economic advantages. Various studies have been reported the acceptable effect of electrochemical process on turbidity elimination. Nonetheless, the effect of simultaneous application of these two processes has not been investigated yet. This study aims to investigate the effect of simultaneous application of electrochemical and coagulation processes on the reduction of coagulant use in surface water treatment. Materials and Methods: this study is experimental type which has been carried out on laboratory scale in a closed system. Water samples were weekly taken from Karaj river-Bilaghan basin during April and their optimum amount of Ferric Chloride (FeCl3) and pH were determined by Jar test. Then, the simultaneous effects of electrochemical and coagulation processes was assessed. Electrochemical process was applied to samples for one minute using iron electrodes along with intense stirring. Turbidity of samples was measured according to the standard method. Results: the optimum amounts of Ferric Chloride and pH were found to be 50 mg.l-1 and 8.5, respectively. After processing, the average turbidity of samples decreased from 9.43 NTU to 0.78 NTU. The simultaneous application of electrochemical process with an electrical current of 0.1 A along with the coagulation process using 25 mg.l-1 and 37.5 mg.l-1 of Ferric Chloride reduced the average turbidity by 89.19% and 90.22%, respectively. Conclusion: results showed that simultaneous application of electrochemical process with a current density of 0.315 mA.cm-2 can reduce the concentration of coagulant by half of its optimum amount.

Abstract: The significance of the transportation network links in the reconstruction period of flood crisis occurrence depends on variety characteristics. One of these characteristics is the accessibility index in the road transportation network. Each of the network links plays a different role in creating the accessibility inside and outside the road transportation network. The more paramount this role is, the more significance that link would be in the network. In the present investigation, reconstruction significance of different link of the Golestan province road network has been determined based on the accessibility index and probability of flood damage. In this paper, for estimation of probability of flood damage, the flood peak was determined based on the maximum daily discharge. In order to assess the flood peak for different return period’s frequency analysis (HYFA) software was used. Finally, the probability of flood damage as a result of destruction of the bridges due to flood was determined. For estimation accessibility index, the roads network was modeled by EMME2 software and then, the network was loaded based on daily traffic volumes. The accessibility index based on the traffic volume was determined and assessed before and after flood. The probability of flood damage is utilized as a coefficient for the accessibility index in the paper. According to the obtained values, the degrees of significance of the different network links were prioritized in the occurrence of flood. The reconstruction significance of different links of road network has been determined based on probability of flood damage multiplied by accessibility index. Generally, it can be concluded that merely using the accessibility index does not suffice in reconstruction significance the transportation network links against flood. Consequently, another index needs to be assessed simultaneously with the accessibility index. This index is in fact the probability of the destruction of the bridge due to flood.

Abstract: Several reports on Excavation in Tehran and resulted risk have been released every year. Though, no estimation of the risk has been recorded. The present paper aims to base on various Fire reports in an 18month-period and classifying the damages including death, physical and financial losses prepare a model firstly in order to weight these damages. Then provide a map of available risks by use of data. The model is designed according to level of injury. The results show that the worst situation belongs to regions 13 and 14. Also, due to lack of clear information the 9, 10 and 11 regions were excluded. It should be said that the obtained map could be used for urban management from one hand and constructors and contactors on the other hand. Final conclusions indicate that the problems pertaining to Excavation not rely on soil conditions however more on lack of engineering information in field of Excavation as well as economic dominance on engineering activities.

Abstract: Present study examines the urban management of Iran after city council establishment (local government).Due to lack of necessary coordination at different levels of performance, monitoring and implementation, affairs management of cities in the world, especially in third world countries have been faced with many problems. In Iran, that is not an exception to this rule, city council has been formed to manage cities in order to solve urban problems. Forming local governments, urban management has entered new stage. Although urban problems have solved partly by establishing these institutions, there are new problems in this context. The main goal of research in urban management after establishing city council (local governments) in term of effectiveness of councils is planning, implementation, monitoring in urban management as well as making appropriate context to operate councils in coordination with urban institutions in order to achieve integrated management. The results showed that the performance of urban management in Iran after establishing councils (public institutions), was appropriate.

Abstract: The significant expansion of Permian sediments in Morrow Mountain is exposed in North of Tabriz. Dorood formation is the first unit of these deposits. This formation is consists of clastic facies that its thickness is about 102 meters, which are lied discontinuous on Devonian igneous rocks and are covered with discontinuities by Ruteh (Middle Permian)limestones. The Permian red facies in the North West of Tabriz are included para-conglomerate, micro- conglomerate, and quartz arenite, sublitharenite, litharenite and shale. Sedimentary structures that formed in these beds and geometry. shape and lateral and vertical expansion of sedimentary strata, associate river depositional environments . Dorood formation deposits in the North West of Tabriz has been created one part of the sedimentary sequence of type 1 with the upper and lower discontinuities bounds of type SB-1. So that the facies of LST part created sedimentary sequences and the sequence is completed with a mixture of carbonate facies TST, mfs, HST of younger formation (Ruteh formation). Interpretation of the depositional environments of these deposits along with similar investigations for younger Permian units in the area could be the basis of deposit basin analysis and ancient geological conditions of North of Tabriz.

Abstract: The use of mixtures of collectors has long been recognised in plant practice and has been shown to enhance flotation performance. These benefits have been reported for a wide range of collector mixtures (anionic, cationic and non-ionic) and include lower dosage requirements, improved selectivity and rates and extents of recovery and an increase in the recovery of coarse particles. Thus, knowing about these interactions can help to improve the present situation greatly. The goal of the present research is to study the effect of the composition of the collector on copper and iron recovery from porphyry ore. In this research the performance of collectors has been investigated in Pure and in the mixture form. To do so, we have used the collectors of Xanthates, dithiophosphates and thionocarbamates. The results of combination of the collectors showed that the best Cu recovery has been achieved with %92.20 in the compositions of the collectors of SIPX with SIBDTM (a mixture of mercapto benzothiazole and dithiophosphate), But the best Cu grade was achieved with %7.58 in the composition of potassium amyl Xanthate with Diisopropyl thionocarbamate.

Abstract: Regarding the fact that equity is based on the return rate expected by the investors and is related with the amount of risk accepted by them and also the share of the market of an auditing firm is considered as an index to increase the quality of auditing, the present research is going to study the effect of auditing firm's share of market on equity cost in firms accepted in Tehran Stock Exchange. To calculate equity cost we have used capm model and to determine the share of auditing market the market share of auditing firm and the dominant share of auditing firm market has been used. In the present research 107 firms accepted in Tehran Stock Exchange during the time period between 2007 and 2011 were investigated. To test the hypotheses we have used a linear regression model. The research findings showed that generally the market share and the dominant share of an auditing firm has a negative and meaningful effect on equity cost. Also equity cost is different (less) in firms when their auditing firm has a dominant share in the market compared to companies whose auditing firm does not have a dominant share in market.

Abstract: Cisplatin is one of the most efficient anticancer drugs which are used in the recent years, there has been an increasing concern on the occurrence of abnormal generation in human beings. As such, the purpose of the present study is to investigate the protective effect of melatonin n the histological changes in the cerebellum of newborn rats which are treated by cisplatin before their birth (during pregnancy). In this experimental study 24 pregnant rats, with NIH race, were distributed to three equal groups of control, interfere I(1), and interfere 1I(2). The Cerebellums of 24 newborn rats were studied on the basis of the changes occurred histologically. In histological observations of both groups: interfere 1 and interfere 2 the layers of cerebellar cortex had irregular tissues (forms). The cerebellum had no foliated shape form and with a perfectly primary shape, it showed some deficiency in its tropil tissues. In interfere group1. The followings were observed: In many tissue and pia matter of soft tissue, pletosis and edematous were seen and in the cover tissue of choroid plexus of forth ventricle and in neurogilia tissue, pletosis and apoptosis were seen dispersely. However, in interfere group 2, there was little pletosis and edematous in pia matter of soft tisse and choroid plexus of forth ventricle were observab and the occurance of apoptosis was not seen. In present study, new events, in line with the proof of infusion mechanism, retardation in the formation of cerebellum in newborn rats which were treated by cisplatin during in-uterine lives were presented. Also, Apoptosis infusion and the distortion of cell structure in cerebellum caused by cisplatin and the anti-apoptosis effects of melatoinin were presented.

Abstract: Virncristine Alkaloid originates from vina-rosea and its mechanism includes the depolarization of microtobals that take part in the process of mitotic divisions (17,2). This drug stops the chain of cell mitotic so that its usage in the halting of divisions in malignant cancers with high proliferation has been suggested (2,17).cerebellum, with respect to the formation and appearance of fetus, is originated from metasfal. The shape of cerebellar neurons and the order of their interstitial space during their development in central nervous system are the same in all vertebrates and abnormal growth of this area causes disturbances in the movement of the given animals.

Abstract: We propose a new asymmetric quantum well structure as a high temperature long wavelength (THz) optical switch based on electromagnetically induced transparency (EIT). In this structure the electromagnetic field of terahertz-infrared radiation interfere with the electromagnetic field of short-wavelength probe field and this effect changes the absorption and refraction characteristic of probe field. Therefore this idea is suitable for terahertz optical switching. In the terahertz (30~300µm or 1~10THz) intersubband transition quantum-well structures, the incoming photon energy is (4~ 41mev) and maybe in the order of electron thermal broadening (KT~ 6meV-25meV for 77K - 300K)[1]. Therefore in the conventional structure, both the incoming photon and the environment temperature can directly excite the ground state electrons to higher energy levels and this problem inhabits the correct optical switching in high temperature and terahertz applications. In our proposed EIT [2,3] based optical switch, the incoming Terahertz IR signal interacts with the short-wavelength (1~2μm) probe field (does not directly excite the ground state electrons) and causes a sharp absorption or transparency in this visible optical probe.

Abstract: Cyclophosphamide (CP), is a cytotoxic alkylating agent and it is widely used in treatment of malignant diseases and autoimmune disorders. CP may be nephrotoxic, both in humans and animal models by generating reactive oxygen species. Vitamin E is a major antioxidant in biological systems acting as a powerful chain-breaking agent through the scavenging of peroxyl radicals. The aim of this study was to evaluate the effect of vitamin E in CP induced nephrotoxicity. Forty rats were divided randomly into 4 groups (n=10). Group1: control group, receiving normal saline, group 2: CP group received a single intraperitoneal injection of CP in saline at the dose of 150 mg/ kg. Group3: CP+Vit E: received CP plus Vit E (100mg/kg), group 4: received CP and olive oil. Twenty four hours after CP injection rats anesthetized and sampled for studying with light microscopy and biochemical studies. Data indicated that serum blood urea nitrogen (BUN) and creatinine (Cr), renal tissue injury index and renal tissue malondealdehyde (MDA) were higher in CP group comparing to CP+Vit E group significantly. Renal tissue glutathion peroxidase (GPx) and super oxide dismutase (SOD) activity were higher in CP+Vit E group than CP group significantly (P<0.05). Our results showed that one of the basic mechanisms involved in CP-induced nephrototoxicity might be oxidative stress and vitamin E pretreatment attenuated CP induced nephrotoxicity.

Abstract: Ischemia-reperfusion injury (IRI) is a common and important clinical problem in many different organ systems. Once the blood flow and oxygen supply are reestablished, reperfusion enhances the injury caused by the ischemic period .This phenomenon, known as ischemia/reperfusion (IR) injury, impacts directly on liver viability, especially during transplantation and liver surgery. The purpose of this study was to evaluate combination pretreatment of melatonin (MEL) and dexamethasone (DEX) on liver I/R model of lung injury. Male Wistar rats (n=60) were assigned to 5 groups of 12 animals each: 1: Sham; Laparatomy without I/R 2: I/R; underwent hepatic I/R. 3: I/R+MEL; hepatic I/R+ injected intraperitoneally melatonin (20 mg/kg). 4: I/R+DEX; hepatic I/R+ injected intravenously dexamethasone (10 mg/kg). 5: I/R+MEL+DEX; hepatic I/R+ injected intraperitoneally melatonin + injected intravenously dexamethasone. Liver subjected to ischemia by clamping portal triad for 30 minutes and was reperfused for 6 hours after ischemia by removing the clamps. Levels of glutathione peroxidase (GPx) and superoxide dismutase (SOD) decreased after hepatic I/R in all groups; levels of GPx and SOD were higher in I/R+MEL+DEX group comparing to I/R, I/R+MEL and I/R+DEX groups significantly(P<0.05), and they were higher in I/R+MEL group comparing to I/R and I/R+DEX groups but it was not significant. Lung tissue malondialdehyde (MDA),lung injury index, and apoptotic index increased after hepatic I/R. Tissue MDA, tissue injury index and apoptotic index were lower in I/R+MEL+DEX group comparing to I/R, I/R+MEL and I/R+DEX groups significantly(P<0.05), and in I/R+MEL was lower than I/R+DEX group but it was not significant. Co-administration of melatonin and dexamethasone had better results in decreasing the lung injury after hepatic I/R, comparing to administering each of them alone.

Abstract: The issue of the effects of bilingualism on cognitive development has attracted different viewpoints. Some believe that bilinguals are superior to their monolingual counterparts simply because they have access to two different language systems. On the other hand, there are scholars who believe that bilingualism can impose negative effects on the cognitive development and intelligence in general. This study aimed at comparing linguistic intelligence of Iranian bilinguals and monolinguals regarding their gender. The participants were chosen from the university students, between the ages of 20 up to 30 years old, male and female. There were 100 monolingual (Persian) and bilingual (Persian and Turkish) EFL learners participating in the study. They were administered MIDAS test, and the results were analyzed through SPSS computer program. The findings reveal that there is a significant difference between female bilinguals and monolinguals linguistic intelligence. However the male participants revealed no difference regarding their linguistic intelligence. The results are interpreted to have implications for language class methodologies and syllabus designers, and can be considered as a support to the idea of promoting bilingual education.

Abstract: Longstanding tradition and modernism in Iran is the old story of those countries that have not yet found the way of independence and emancipation of the self encountering western culture and civilization and stayed caught within the viscous cycle of Modernism or Traditionalism. Cultural weakness and passivity of Islamic Societies before new life of the west has converted into the basic problem for countries like Iran, crossing from tradition and reaching to modernism so that its impact for generation of the nation has led to thoughts and patterns each of them have affected scientists, scholars and people for some time. Pure fascination with western culture and civilization, absolute rejection and opposition with it and attempt to keep the optimal values of the national culture and identity are three approaches that have formed creation and development context of intellectual streams in the course of history over the years. Understanding the intellectual attitudes and their impacts on the ups and downs of Islamic Iranian Thought without doubt help how to deal with this phenomenon in the present time. It also requires an understanding of two issues (tradition and Modernity), an overview of the history of Iran from tradition perspective and valuation of the perspective that Iranian society is facing the name of Modern Community.

Abstract: Risk measurement is one of the main stages in Project Risk Management. It quantifies risks and assesses their impact on project’s outcomes (time, cost and quality). Monte Carlo simulation, as the best practice, has been used to developed several models to analyze and quantify risks in projects. Bayesian Networks (BNs), as a powerful technique for decision support under uncertainty, have attracted a lot of attention in different fields. This paper aims to use BN capabilities to introduce a new approach for project cost risk modeling. The new approach explicitly quantifies uncertainty in project cost and also provides an appropriate method for modeling complex relationships and factors in projects such as: causal relation between variables, common causal factors, formal use of expert judgments, and learning from data to update previous beliefs and probabilities.

Abstract: Today, as organizations improve their ability to compete globally, we see that competition innovation and creativity are now shifting to the supply chain. Increased competitive advantage can be achieved only if all supply chain stakeholders are coordinated and integrated with one another. This integration must be created among suppliers, intermediaries, third-party providers, and customers. In addition to the forward supply chain, reverse logistics must also be considered. Amid business complexities, smart organizations are reusing, recycling, and remanufacturing using third-party reverse logistics providers (3PRLP), which affect the performance of the entire organization. The selection and evaluation of reverse logistics providers is important to improving outcomes. Several attributes should be used to select and evaluate 3PRLP. In this paper, an analytic network process (ANP) is used to investigate feedback and relationships among attributes and to identify the most important attributes in the selection and evaluation of 3PRLP. Then a multi-criteria group decision-making is upgraded in uncertainty conditions to guide the process of selecting the best 3PRLP. To deal with uncertainty, intuitionistic fuzzy set (IFS) and grey relation analysis (GRA) will be used.

Abstract: Biofilm production potential of clinical isolates of Pseudomonas aeruginosa were investigated in this study. Isolates from blood and wound produced biofilm but wound isolates produced relatively higher amounts. Sequential passage of the P. aeruginosa strains in biofilm culture in trypticase soy broth (TSB) resulted in gradually increasing amount of biofilm production the by isolates whereas passage of the same isolates in planktonic culture did not result in enhanced biofilm production. Passage induced enhanced biofilm production reached maximum level at passage 3 (P-3) for the strains B-6, W-2 and W-14 and at passage 4 (P-4) for the strain B-9. These values were 64.7% 83.4% and 75.6% and 72.8 % increased biofilm production by the biofilm passaged strains in comparison to their plantonic counterparts. Ferric ammonium citrate (FAC) which inhibits biofilm production by P. aeruginosa, was only partially effective in reducing biofilm production by bacteria passaged in biofilm. On the other hand, FAC efficiently reduced biofilm production by cultures which were grown in planktonic state. Taken together, the results of this study indicate that growth of P. aeruginosa in biofilm enhances its potential to form new biofilm.

Abstract: This paper presents a methodology to incorporate Modified Fuzzy Possibilistic C-Means (MFPCM) with Repulsions clustering and Generalized Gradient Vector Flow (GGVF) snake algorithm for lesion contour segmentation on breast ultrasound (US) images. Preprocessing US images is mandatory and involves two stages- Memetic Adaptive Neuro Fuzzy Inference System (ANFIS) to remove speckle noise and Hough Transformation for contrast enhancement. Segmentation is performed on preprocessed US images based on region-of-interest (ROI) and the lesion is separated from background using MFPCM with Repulsions. To further improve the shape, boundary of the lesion is identified using active contour method, GGVF snake algorithm. The proposed methodology is compared with the Fuzzy C-Means clustering and traditional contour detection methods for a database of 50 lesions (18 benign and 32 malignant cases) and yield better results in detecting the boundary of the lesion. The shape and size of the lesion classify the lesion as, benign, pre-malignant and malignant. The proposed method assist radiologists to determine and improve the efficiency of ultrasound breast cancer image elucidation.

Abstract: Objective: To assess the levels of cervicovaginal biomarkers (HCG and FFN) and serum CRP in primigravida women who terminated their gestation with term labor versus those who delivered prematurely. Design and setting: In this nested cohort study, 89 patients with symptoms of labor were enrolled in Beasat Hospital in Sanandaj, Capital in Kurdistan province, in Iran. Methods: Data regarding the patients’ age, education, BMI, and hemoglobin level were recorded. Laboratory test results including the levels of CRP, FFN, and HCG were also recorded and patients were monitored until the end of gestation to obtain the ultimate pregnancy result (preterm/term). The mean difference between groups was determined using the t test. Results: 43 patients were 21-24 years old, 53.93% patients had a BMI of 20-24, and 63.87% patients had term labor. 49.43% were CRP negative . 26 and 80 patients were HCG negative and FFN positive respectively. FFN and CRP were the only markers that were significantly higher in patients with preterm labor (P<0.001). Conclusion: FFN appears to be the strongest predictor of preterm birth followed by CRP, whereas HCG assay may not render a reliable prediction of preterm birth.

Abstract: Healthcare research recognizes that satisfaction is an important health outcome of the medical encounter. As a result, many healthcare professions have paused the development and validation of instruments for measuring patient satisfaction. The present descriptive study was carried out through cross-sectional method. A sample of 400 patients was chosen randomly from seven hospitals- affiliated to Arak University of Medical Sciences of which a total of 305 responded to the questionnaire during November and December 2011, giving a relatively high response rate (76.3 %). To confirm the reliability of inter-item correlations and construct validity, factor analysis was carried out, and items belonging to each factor and Cronbach’s Alpha Coefficient were calculated. Seven dimensions were identified, including: doctor's communication, nursing care, convenience, visitors, cleanliness, costs and general satisfaction, explaining 60% of the variance. All items, except one, revealed loadings above 0.4. Cronbach’s Alpha exceeded 0.8 for all dimensions, except for the area of visitors (0.66). Results must be interpreted with some caution due to the high level of satisfaction and not be considered comprehensible evidence of high performance of services or programs without substantial additional information. It is advised to use a qualitative study to complement such studies. In the light of the results, the designed hospital services satisfaction questionnaire strives to be a valid and reliable instrument for assessing inpatient satisfaction with hospital services.

Abstract: In recent years, the cone penetration test (CPT) is considered as one of the most important In-situ tests, because of its simple, fast, reliable, and economical nature. The scale effects between the pile toe resistance and CPT cone is considered by different researchers, while the effects of these factors are not taken into account in making a relation between CPT sleeve friction and pile shaft resistance. As the main purpose of this research, in order to study these effects on the shaft resistance, the shear strain produced under CPT sounding and pile load tests were studied. Then, there was an effort in relating the scale effect between CPT and pile to the shear strain levels. As a result of the difference in the rate of penetration, the effect of generating excess pore pressure that is important for fine grained soils is considered. The database consists of 42 case studies of pile load tests include the CPT profile is collected from 24 different sites. Next a method is presented in determining the shaft bearing capacity, with considering scale effects and this method is evaluated to four methods including: Clisby et al.,Tumay and Fakhroo, Price and Wardle and Takesue et al.The result of analysis showed that the proposed method estimated the shaft capacity with the highest accuracy in comparison to other methods.

Abstract: Aim: In this study we intended to isolate and identify Azo dye biodegrading and decolorizing bacterial strains as well as investigation of biodegradation mechanism. Different bacterial isolates were isolated from dye contaminated soils behind textile factories and tested against Reactive Violet5 (RV5) dye. The most potent isolate was identified as Bacillus cereus via partial sequencing of 16srRNA DNA . The decolorized sample showed lowering of peak to a smaller absorbance value for dye concentration of 200 mg/L, which informs that the decolorization is due to removal or degradation of dye. The comparison of TLC chromatograms before and after decolorization by B. cereus under UV light showed that the original dye was quite different from the supernatant obtained after dye decolorization, which was suggested by different values of retention factors obtained in the TLC experiment This difference confirms that decolorization was due to breakdown of dyes into unknown products. The identification of several degradation products from purified RV5 by Bacillus cereus was achieved with FTIR spectroscopy, 1H NMR and GC-MS. The results showed four compounds, nitrobenzene, 4-nitrophenol, 4-nitroaniline, and 4-nitroanisole, as degradation products.

Abstract: Iran history witnesses four periods of opening in sociopolitical structure that affected press by other institutions and phenomenon. Press qualitative and quantitative development in mentioned periods, are one of the positive changes in journalistic zone. If development in sociopolitical structure affects press, it will play an important role in supporting and maintaining of the structure. This takes place by reforming a semantic system that calls for the support and development of this structure. In this paper by using discourse analysis, four newspapers in the periods of Iranian Constitutional Revolution 1285-1289), Premiership of Doctor Mosadegh before the Revolution (1330-1332), the Islamic Revolution (1357-1358) and seventh terms of presidency election after the Revolution (1376-1380) have been studied so as to determine common and separate features of them after recognition of semantic system offered by papers. Common features of the periods, development of sociopolitical structure and common features of chosen newspapers indicate supporting the structure and attempt to keeping it. The results indicate that Constitutional Revolution up to now has been represented in different ways by putting in a row the semantic system of newspapers while having development in sociopolitical structure that enjoy common features than separate ones. “Law”, “Freedom” and “People” have been the main factors of press semantic system within the period (1285-1380, Solar Calendar).

Abstract: The aim of this study was to investigate the features and development of functional neurotic responses among adolescents, to elaborate practical recommendations for preventing neurophysiological disorders and neutralizing their effects. Based on the statistically representative data obtained from healthy adolescents, a positive correlation between the formation of adaptive responses and perinatal & family situation, interpersonal, and living conditions (e.g., birth pathology, poor living conditions, parental divorce, incomplete family, family relationship problems), as well as a number of extremal factors (e.g., emotional stress, studying conditions, interpersonal relationship) that disclose the ethiological factors inducing borderline neuropsychic disorders was detected. The use of biological feedback based on electroencephalography allows one to perform the correction of neurotic responses, resulting in a decrease in vegetative disorders and improvement of the general psychophysiological condition of adolescents. In adolescents with somatic disorders, more pronounced shifts from the vegetative nervous system are observed at the disadaptation stage, which presumably is one of the factors contributing to the emergence of a disease or its exacerbation under stress.

Abstract: Nowadays, with the amazing advances in the management knowledge, existence of organization's performance assessment system is inevitable. Health System Performance Assessment helps to decision-makers and Policymakers to be ensure responsiveness of their decisions. History of Health System Performance Assessment returns to decade before 2000, but after World Health Organization Report (2000), the issue of Health System Performance Assessment has officially entered in the health literature. In this study, using related key words and related electronic and library resources from 1998 to 2012 have been investigated in both Persian and English language. Initially, the most common and most important of international models of performance assessment in the health has been studied and compared and About 150 criteria and 450 indicators that are involved in the performance assessment of the health system have been extracted. Then by using the survey form of the experts and professionals, 49 criteria related to the performance assessment of the district health network is extracted. Then by using the questionnaire the amount of effect of each criterion on the performance assessment of the district health network has been measured. By performing exploratory factor analysis on the resulting data, five main components have been discovered. In total, these five factors have explained about 65% of the variances. The first main component that has been named Characteristics of Service Delivery has the largest share (16%) and the fifth main component that has been named Primary Health Care has the lowest share (10%) of the performance assessment of the district health network. Because any assessment model is not complete and perfect, to correction of the defects by the constructive criticism of experts and professionals, designed models should be published both before and after applying. It is recommended that the designed model in this study be applied practically to performance assessment of the district health networks, and then the policymakers and decision-makers should be informed of the results of the practice to identify the strengths and weaknesses of the model and to give recommendations for modification of the model.

Abstract: The present study seeks to evaluate the effect of earth dams construction pace of soft soil on stability of its slopes. To achieve it, two types of earth dams with the same height and material characteristics and two different slopes of 1:5 and 1:2.5 were selected and evaluated through Plaxis V8 modeling software. The findings show that by increase of dam construction pace, the horizontal and vertical displacements maximize and a severe increase enhances displacements consequently.

Abstract: Today’s monitoring has been regarded as one of managers’ duties. Using this can achieve maximum effectiveness and productivity and organizational goals by application of organizational resources and activities. Educational systems need to reach learner-based education and improving their effectiveness through establishment of educational quality. Thus, intrinsic motivation to learn and presented knowledge will be changed into a skill. Also, by creating and improving learners’ self-confidence the practical competences will appear and get used. As a result, one of significant factors in educational development is monitoring educational programs. Therefore, the present study aims to deal with current situation of monitoring on educational performance of higher education center as a major factor on educational performance and educational systems. It also attempts to provide an appropriate model accordingly. As one of principal elements in ruling a country, monitoring and its different ways have been developed within time passage. These changes have been more accelerated in recent decades, though in third world countries it is regarded as a deterrent to executive affaires. But in developed countries monitoring has a special place (Bighdeli, 1997).

Abstract: The increase of roadways in metropolitans as well as congestion in high-rise constructs, current landscapes of cities as proximity to tall buildings have been cut off by an asphalt path have been defined as an street. However due to everydays mental stresses the need for making more communicative interactions with nature, other humans and environment found to be a necessity. These fields within last decades have loosed their application because of insufficient attention and care. The present article aims to besides studying concept of urban spaces, stages and various aspects of urban structure appearance in social interactions. As the second purpose, it is going to investigate on urban field and provide a couple of structural approaches in designing these spaces to strengthen social interactions of citizens. The study tracks an interpretive-analytical method and library studies in addition to electronic and printed information used. An appropriate urban field has been designed based on right realization and planning is considered as an urban open space which is a place for movement, stop, rest, and time to enjoy the social interaction. Of one important approach in this article can mention to organizing a variety of applications based on time, temporary exhibition spaces designed to sell and supply goods and furniture design are tailored to the needs of residents.

Abstract: WTC (willingness to communicate) emerged as a concept to account for individuals' first language (L1) and second language (L2) communication. It is important to know what factors affect WTC in acquiring English proficiency. It has been conceptualized a heuristic model according to which authentic communication in L2 could be seen as a result of complex set of interrelated variables. They claimed that their heuristic model can provide a pedagogical use for L2 education. Relations among L2 learning and L2 communication variables in the Japanese context.In his model, a latent variable, international posture, was hypothesized to capture the general attitude toward the international community and foreign language learning in Japan. The current research is intended to partially assess Yahima's model concerning the relationship between attitudes defined as international posture and WTC. The data for the study were collected students studying English language teaching (ELT) in Tabriz Azad University by using five surveys in instruments. Data analysis showed a positive correlation between attitude (international posture) and WTC, and also a direct path from attitude to WTC. All components of attitude (international posture) including Interest in International Vocation/Activities (IVA), Intercultural Friendship Orientation in Learning English (IFO), Interest in Foreign Affair (IFA) and Intergroup Approach Avoidance Tendency (AAT) had positive effects on WTC. In this research, Tabriz Azad University students demonstrated positive attitude which made them have high WTC and motivation.

Abstract: Knee osteoarthritis (OA) is one of the most common causes of disability in the older. Myofascial pain and dysfunction is partly responsible for pain and disability in this condition. This study investigated the efficacy of myofascial trigger point therapy on knee OA. In randomized clinical trial, 60 patients with bilateral knee osteoarthritis were divided into two 30 persons groups. Thirty patients were received 16 sessions of usual physical therapy. In addition to physical therapy, intervention group were received myofascial trigger points. Assessed Variables included pain, joint stiffness, physical function, range of motion of the knee and physical performance. There were no significant differences in assessed variables between two groups before treatment, statistically. After treatment, the above variables compared with the pre-treatment results of same group and then with the post-treatment results of the other group. Except for physical performance which was not significantly differing in control group, both groups demonstrated improvement in all variables after treatment. However, comparing the two groups revealed that all variables in intervention group are better than control one except for joint range of motion. Physical therapy is an effective approach for treatment of osteoarthritis of the knee. This effectiveness can be enhanced by adding the treatment of myofascial pain and dysfunction syndrome.

Abstract: In this paper a method is proposed to fine-tune the performance of matched filter using a Gabor filter structure to improve the overall vessel segmentation accuracy. The proposed Gabor filter structure classifies each pixel as vessel or non-vessel based on the output of matched filter and several other features extracted on the pixel level. The vessels are detected by thresholding the retinal image’s response to the matched filter, while the threshold is adjusted by the image’s response to the Gabor filter.The ground truth output is available from images labelled manually by observers. Several experiments were conducted to achieve better performance for matched filter and the error in pixel segmentation between the available ground truths.

Abstract: The purpose of the present research is to study the relationship between different parenting styles (authoritarian, autocratic, and permissive) and the educational achievement of students. For that matter, a sample of 262 people has been chosen amongst male and female students at the first grade of theoretical high schools in the city of Karaj, through the multi-stage cluster sampling method. The necessary data has been collected by the use of measuring tools like the parenting style questionnaire of Diana Baumrind (1971). The validity and reliability of the mentioned questionnaires was confirmed. The results of multivariable regression analysis, obtained through the simultaneous method, had indicated that there was a meaningful and positive relationship observed between the authoritarian parenting style and the academic achievement, and there is not a relationship observed between the two other styles (autocratic and permissive) and the educational achievement. Also, there is a meaningful difference the educational achievements of male and female students, which was clarified through the statistical test for the independent mean differences (the independent t).

Abstract: Oxidative stress is suggested as a mechanism underlying diabetes mellitus complications. The main objective of this study was to investigate the effect of sage leaves extract on oxidative stress of hepatic tissue in isoniazid-induced diabetic rats. The lipid peroxidation product, malondialdehyde (MDA) and reduced glutathione (GSH) content was measured to assess free radical activity in the liver tissues. The enzymatic activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) were measured as indicators of antioxidation in liver tissue. Wistar rats were made diabetic with a single injection of STZ (75 mg/kg i.p.). Rats were randomly separated into four groups, of 10 animals each: Group 1, healthy control rats; Group 2 non-diabetic rats treated with 50 mg/kg b.w./day intraperitoneal injection of sage extract; Group 3, diabetic rats; Group 4, diabetic rats treated with sage extract (50 mg/kg b.w./day, i.p.) for 8 weeks. At the end of experiment, MDA contents of the liver tissue in Groups 3 was found to be significantly increased as compared with Group 1 (P<0.05) and liver MDA level in Group 4 were significantly decreased as compared with Group 3 (P<0.05). The GSH, SOD, CAT and GSH-Px contents of the liver in Group 3 were significantly decreased as compared to Groups 1 (P<0.05) and were increased in Group 4 as compared to Group 3 (P<0.05). The results obtained, demonstrated that sage extract alleviate oxidative stress of hepatic tissue in streptozotocin-induced diabetic rats.

Abstract: Based on contemporary DNA distributions and cautious inferences on migratory histories, considering previously localized the potential geographic origin of haplogroup G-M201, by using high-resolution phylogenetic relationships containing both G1-M285- and G2-P287- related lineages, this research tries to find some genetic evidences to trace the spread of early Neolithic agriculture in the Northwest of Iran. For Iranian Azeris, the presence of haplogroup G-M201 has been associated with the spread of agriculture, as it reported especially for the European context (King RJ, et al., 2011). Considering general frequency pattern of haplogroup G in Iranians, it could be inferred that mountainous and unique harsh geography of west and northwest of Iran might facilitated the establishment of specific lineage of Neolithic agriculturalists, e.g. G haplogroup, in the region. However uninhabited Great Salt Desert created particular sharp border in the center and east of the country and cut further distribution of these lineages to the eastern neighbors and east part of Iranian plateau. Diversity of subhaplogroup G2-P287 among Iranians and coalescent time of the lineage formation in the region reflect a phylogenetic branching event that is in consistency with historical events. In this study, the distribution of informative G sub-clades from the Near/Middle East and the Caucasus has been studied.

Abstract: In modern wars (sixth generation) enemies take the "removal of activities" policies instead of "removal of people". Regarding this issue in passive defense, designing "safe place" and "refuge" is definable. Safe place is designed and built for short-term use during tension. This place is of vital importance when we cannot use the exits due to destruction or unsuitable circumstances (like infections and insecurities due to the continuance of tension). Safe place must provide necessary equipments to protect people, maintain and control rudimental activities, and continue function in architecture as long as the rescue forces arrive and the situation gets normal. Living in refuges provides temporary accommodation and living situations for one to two months. It also provides protection and organization of activities and management of circumstances and resistance and protection of municipal lifetime. Based on what reviewed, we should foresee following characteristics for these kinds of places: (1) Resistance against blast wave. (2) Resistance of the foundation and shell of the construction against debris. Due to the change of policies in sixth-generation wars, the experiences of imposed war and the wars of the second half of 20th century will not have efficient use if a new tension occurs. In this descriptive-analytical study, the researcher tries to use the experiences of the important wars of fifth-generation wars to optimize the designing of safe places and refuges according to the needs of sixth-generation wars. Finally some strategies and solutions to design and build these kinds of place are given.

Without doubt, unsustainable consumption of nonrenewable natural resources like fossil fuels, the Environment will be at risk in the near future. While, the building sector accounts more than a third of energy. Therefore reduce the amount of energy in Buildings causes toward sustainable development which consistent with the needs of today's generation which put future generation at risk. One of the painters of sustainability in architecture is the use of natural energy and fossil energy consumption and minimum natural environmental conditions and climate so solar building designs which is a step towards its achieving .In this article, has been expressed the important factors in solar buildings design . These factors are included external factors and internal factors. More owner implementation strategies in the design to same energy in buildings also will be presented.

Abstract: There are a number of elements impacting the expansion of current groundwater resources, including the role of structural operators viz. faults, seams and gaps, lithological agents among them are the structure of region and topographical elements like the slope and the height of the area in question. Geomorphologic processes and forms are among the most important elements controlling the supply, direction of flow, quality and quantity of groundwater resources and have a serious impact on them. For this reason, in current research, incorporating field studies with remote sensing (RS) we embark providing different maps of affecting factors on groundwater resources and finally incorporating them in Graphic Information System (GIS) which leads to geomorphic map of Saremsaghloo-Gharecharyan map in the Zanjan province. Afterwards, the figures and phenomena obtained are used as a ground for comparison and evaluation of their relationships with groundwater resources in question. According to the conclusions obtained from current research, there is a close relation between geomorphologic phenomena and groundwater resources which shows the possibility of using geomorphologic phenomena for locating groundwater resources. One can mention, according to these facts that plain's north highlands, floodplains, alluvial terraces and alluvial fans are among the most influential elements affecting groundwater resources. On the basis of relation between geomorphologic phenomena and groundwater resources, those regions capable of groundwater resources were diagnosed. After that, a number of suggestions have been putted forward for reinforcing and improving the Saremsaghloo plain, like locating appropriate places for artificial feeding of groundwater resources and constructing underground dams in those areas having groundwater and proper context.

Abstract: Earth quake is a dangerous event that kills lots of humans and leaves horrible economical & financial damages every year. The seat of Iran on world earth quake hazard zone, clarify the sensitivity of security issue confront these unpredictable disaster. Most of the desert cities of Iran have traditional texture that involved historical buildings so access to open safe area is too important for scrapping and guarding. Therefore this issue attempted to investigate of harm resistance of special structure of traditional houses against earth quake, by ARABS set of buildings in Yazd as a case study. As regards access to open safe area during of crisis specially earth quake disaster, and supply services either in limited time is so survival. Therefore less accessibility problems and its ruination probability make a serious hazard. This paper with propose of catching the pattern for resent residential units, investigated briefly to adequate of open area of traditional residential units (equal of neighborhoods in new definition) and approachability to these open safe areas tile crisis. In this issue also consider about its complex relationship among the spaces & rooms because of specific centralistic structure, accentuate on safety and security foundation with analyzing data that based on gathering with statistical and experimental methods, by SOWT methodology and verifying spaces with adaptation information. In conclusion, as result of this issue spatial arrangement of this traditional house, consideration of its coordination and dimensions, intrinsically reduce damages financially and physically of earthquake in crisis time and increase the escape time and improving the quality of humans life.

Abstract: Introduction: Ectopic pregnancy (EP) is potentially life threatening condition. Methotrexate (MTX)is widely used in treatment of EP. The aim of current study is to compare single dose and multiple doses of MTX in treatment of EP. Methods: In this randomized controlled trial 78 patients with unruptured EP who were hemodynamically stable and had EP size less than 4 cm were enrolled in the study during 2008-2011. All patients were undergone transvaginal sonography and β-HCG titration. Patients were randomly assigned into two groups either to receive 50mg/m2 intramuscular Methotrexate (MTX) or 1mg/kg/day intramuscular MTX in days one, three, five and seven till β-HCG decreases at least 15%. Data were analysed using SPSS 20.0 software. Results: Baseline characteristics were similar in both groups. There was no significant difference between teo groups in treatment response. (P=0.255). β-HCG decreased percentage was significantly higher in single dose group in comparison with multiple dose group.(P=0.046). β-HCG decreased percentage wasn't significantly different in two groups. No difference was seen in two groups in drug side effect rate. Conclusion: Treatment of EP with single dose MTX is recommended because of lower costs and time needed.

Abstract: Drought is one of the most dangerous natural misfortunes that influences on human society more than others. There are various Meteorological Drought Symbols to study drought. Although there isn't any absolute preference between these symbols but since each symbols has been synthesized for a specific aim, it might be various results based on being or not being drought, then some of them are better for specific areas and applications. Drought is a Meteorological phenomenon that can be found not only in arid and semiarid areas but it can be also found in the moist areas. Then, it is necessary to study on Drought scientifically to decrease effects of Drought. Since Drought can be considered as a hydrologic phenomenon, it should be used Hydrologic Phenomena Methodology to study. Hydrologic Drought is associated to significant decrease of water level of lacks, rivers, reservoirs, etc and Agricultural Drought is a position that moisture content in the soil isn't enough for products. Meteorological Drought is a position that real precipitation is lesser than expected precipitation in the area. If this Drought is continued, it will be led to Hydrologic Drought and Agricultural Drought. It is clear in the controlled area, i.e. Sistan& Balouchestan Province. In this study, Place and Time Patterns, Meteorological Drought Methodology in Sistan& Balouchestan Province are determined and categorized by Interpolation of Normal Z, Rainfall in Geographical Information System (GIS). Climatology of Meteorological Organization and Ministry of Energy will be also determined by using dimensionless criterion method and variable average of dry and wet years during statistical period. on the basis of results from categorizing drought, it found that Drought decreases from north to south and precipitation has been changed each year. Chabahar Station doesn't follow on the given theory and its humid is provided by the sea and doesn't need to ascending factor in the precipitation mechanism. But in other stations, it follows on Convectional Factor that experienced the most frequency and also high level disturbances that are the most plenty of ascending mechanism.

Abstract: In recent decades tourism industry is one of main reasons of the social and economical development for many countries; so these countries try to gain more portion of it for themselves. The excessive natural and cultural touristy potentialities in Iran made this country to be one of the most attractive sightseeing areas, although; Iran has got the lowest rate of tourists. Khark Island is about 32 km. It is a beautiful coral reef coast; about 98% of oil export has been done through this place. The ecotourism potentialities of Khark and Kharko Islands (about 3.7km far from Khark) are the reason to consider ecotourism and the main activity in these islands which is exporting oil at the same time. This article refers to way of measuring the geographical coordination of the place, and the potentialities, ecotourism attraction of the islands and introduces some ideas in order to expand tourism in the islands.

Abstract: The practice of foundation engineering was largely empirical until 1925, when K. Terzaghi, often called the "father of soil mechanics" published his book "Erdbaumechanik auf bodenphysikalischer Grundlage." From this point onward, and with the years from 1950 onward being especially fruitful, founda­tion engineering has developed into a more rational approach. This is not to say that there is not still a large element of "art" and empiricism in the practice, but the currency tendency is to rely much more on laboratory testing and recognized principles of the behavior of elastoplastic solids than was done earlier. Much laboratory work in the area of soil behavior has been done and reported in geotechnical literature jr. recent years. Most of this work has been done on samples prepared under ideal conditions in the boratory. This tends to produce samples which are rather homogeneous, uniform, and generally lacking in geological aging so that those properties of anisotropy and cementation are often not produced. A few laboratories attempt to reproduce anisotropy, but the practice does not seem to be widespread at present. Reproducing aging and environmental processes in the laboratory to obtain natural cementation effects is generally too time-consuming to be practical. Tests on laboratory samples, how­ever, constitute a large part of the data base on which empirical correlations and field predictions are made. When one takes into account the actual soil makeup, its geologically obtained properties, and the difficulties of obtaining samples which have sufficiently small amounts of disturbance that the resulting test data are reliable, test data on laboratory prepared samples may bear little resemblance to field performance.

Abstract: In modern architecture, to reach full achievement in urbanization and build an ideal city for citizens needs considering the fundamentals of sustainable development. The theory of sustainable development and consequently sustainable architecture is one of the most controversial discussions in modern architecture. Each construction should make a link to the environment that is located in. The challenge here is the kind of the link. In this analytical study, that is a case study of Dezful city and uses library research, we tried to discuss the issue based on the literature. To build a sustainable environment and sustainable development suited for men habitation, so many problems are involved among which energy consumption in building complexes for heating and cooling, goods maintenance etc, needs more revision regarding designing, executing and programming the places and the forms of the architecture. Subterranean and croft pit are good cases in old cities, which were used for cooling, heating and maintaining food in Iranian cities. In this study, the researcher introduces values and qualities of the framework used in Dezful old architecture that are applicable for sustainable design. Dezful'z old architecture managed to be compatible with the harsh weather using certain strategies that knowing them helps us to reach suitable patterns for sustainable development in new architecture sites.

Abstract: Introduction: Pneumothorax can lead to severe respiratory distress and acute heart conditions. Dyspnea, agitation, tachypnea, tachycardia, hypotension, altered mental status and decrease in respiratory sounds are its signs and symptoms. The aim of this study was to assess the prevalence of delayed pneumothorax among patients with penetrating chest trauma who have a normal CX-Ray on admission. Method: In this descriptive study 172 patients with penetrating trauma who were asymptomatic and had no signs of pneumothorax or heamothorax in their initial chest X ray were included. Demographics and history and physical examination data were collected. All the patients were studied for delayed heamothorax and pneumothorax by chest X ray. The incidence of delayed heamothorax and pneumothorax were compared in one and 3 hours after admission using descriptive statistics and SPSS software. Results: Mean participants age was 25.24±7.91. Among the participants 167 (97.1%) were male and 5 (2.9%) were female. In 103 patients (59.9%) the trauma was in front and in 69 (40.1%) was in back. Incidence of delayed pneumothorax and heamothorax was 0% in one hour after admission. The incidence of delayed pneumothorax was 0.6% in 3 hours after admission. Conclusion: Considering the incidence of delayed pneumothorax between 1 and 3 hours after admission of the patient it isn’t recommended to decrease the duration of follow up to 1 hour.

Abstract: Water in soil adversely affects cohesive soils by reducing the cohesion by soften­ing, and may cause bulking of cohesionless soils depending on the amount of water present. If sufficient water is present to develop pore pressure [changes in water height in a piezometer tube (see Fig. 2-7a)] there may be a marked re­duction in the  tan component of the shear strength. Permeability is the facility for water flow through a soil mass. It is a major factor in soil drainage, well water supply, and construction dewatering. All natural soil deposits contain free water in their voids. After prolonged dry periods the amount of water may be quite small near the ground surface; how­ever, immediately after a rain the voids may be nearly filled. In their upper zone the natural water content wN and soil strength are transient phenomena. At nearly all points below the soil mantle there is a zone of flowing water called the water table. The soil below this point is saturated; however, individual samples may have trapped air bubbles and produce S slightly less than 100 percent. The water in this zone is flowing under a hydraulic gradient from a higher to lower energy level. The water level in a series of piezometers inserted along the direction of flow will define the hydraulic grade line. Above the water table is a capillary zone (S 100 percent) where the voids are also nearly filled with water. This water is held in place by surface tension between water mole­cules and soil grains and is not free to move. The water in this zone produces an increase in the effective weight of the soil. The depth, of water below the water table produces a buoyant effect on the submerged soil.

Abstract: this regard, questions about the real situation of the collected, recorded, processed and analyzed information to support decision making in the field of maritime safety and environmental protection, are asked. These questions should be understood in an effort to "conceptualization" of the world that cannot be objective and as long as there is not sufficient transparency in realizing similar concepts and not appropriate assistance (including technical cooperation, political, administrative, etc.), complete potential of marine vessel traffic control information systems, will not be released. In this regard, the data analysis is necessary to ensure value judgments in data collection and interpretation and providing an effective basis for decision-making fully understood. Recently, VTS capabilities significantly have changed and have become a multi-functional tool. This is due to the technological advances and social expectations. This paper has conducted to investigate the factors influencing personnel performance in activities that are carried out in marine vessel traffic control center and in this regard provides an interactive model. Also, providing of an effective way to deal with factors affecting the performance of personnel who are dealing with the issue of marine vessel traffic control is other objective of the paper.

Abstract: Introduction: Always motivation of people in occupational activity has been analyzed by researchers. Staffs have specific extrinsic and intrinsic motivation for their jobs; this attitude can cause challenge or devastation in Critical situations. This study has examined the view of 5 Crisis Groups about occupational preference. Methods: This is a descriptive cross sectional study. The population under study was employees of medical emergencies, Red Crescent, nurses, firefighters and ordinary people in province of Kermanshah. Data were collected by questionnaire of Occupational Preference Inventory (WPI). It has 30 questions, Two dimensions and 11 two subgroups. The reliability and validity of the questionnaire has been confirmed repeatedly by foreign and internal studies. Data were analyzed by Spss16. Results: All of the 75 subjects were men and selected from people with job experience of more than 5 years. 15 people that were ordinary don't have governmental job. But they were selected for assessment of their extrinsic and intrinsic motivation in the crisis. The results showed that intrinsic motivation of emergency medical personnel, fire, nurses, Red Cross and ordinary people were 90%, 89%, 88%, 85%, 80%, respectively. Extrinsic motivation in employees, fire department, emergency medicine nurses, Red Crescent and ordinary people in crisis, was 91%, 90%, 89%, 88%, and 85% respectively. Conclusion: Results have shown the different attitudes of the employees associated with the crisis. Knowing your job and your own superior knowledge of crises and conflicts between jobs can distort the coordination and planning required in critical situations. However, existence of various extrinsic and intrinsic motivations requires the study and training of the existing forces by disaster planners in order to make maximum use of existing forces.

Abstract: self-care is one of the most important factors in controlling diabetes. After educating the patient on how to control the disease, there is no team treatment care as effective and efficient as self and family care. However, sometimes self-care is not possible due to certain barriers which inhibit the patient’s role in controlling the sickness. So this study aims to identify what the barriers are and how they are associated with diabetes control. the sample includs 225 diabetic patients (Type II), selected randomly from the population. The collection instrumentsconsist of demographic and self-care questionnaires the latter of which contains 34 questions on barriers of self-care behaviors scaling from low (1) to high (5). At the beginning of the study all cases are tested for HbA1c. To investigate the relationship of the obtained results and the studied variables Spearman Correlation is used. The finding show many barriers to self-care behavior including high costs, high work engagement, depressive effect of the treatment, forgetfulness, unawareness of the self-care program, having no tendency to the program, unawareness of blood glucose test interpretation and disbelieving self-care results. Among these factors high care costs(r=0/24) and depression(r=0/21) are strongly associated with higher HbA1c levels. It is concluded that helping the patient in self-care is one of the most important factors in succeeding to manage diabetes. Therefore, in addition to educating patients on self-care, the curing team should guide them on eliminating barriers and gaining better results.

Abstract: As humans, organizations can be forgetful. The objective of this study was to propose a model by which healthcare organizations can use it for healthcare knowledge management. Through a systematic review all journal articles published in the academic business literature between 1991 and 2009 that used the term “organizational memory” and related terms with the term ”model” were reviewed. The final sample of 19 models were analyzed according to the parameters of the study. The parameters were: Having clear inputs, processes, layers, networking and being process - oriented. The majority of models have focused on components of the OM in terms of inputs (12 models) and OM process or steps for building an OM (14models). Eight models were clearly mentioned to organizational processes and only three of 19 models clearly revealed networking. We provided an organizational memory development Process model (OMDP) which consisted of three main phases: Planning phase, Implementing phase and Evaluation phase. Considering the diversity of healthcare information and knowledge, Selecting a single model would not be enough for all aspects of healthcare. Therefore a memory of memories would be ideal for healthcare enterprise.

Abstract: Prematurity is the major cause of neonatal mortality, so this study aimed to determine the perinatal factors related to the premature infant’s mortality. Sample of records of this historical cohort study, was premature infants hospitalized since 1386 to 1389. 200 cases were randomly selected. After sample loss, 172 files precisely were studied from admission to discharge. Data were collected using a validated questionnaire. Finally, patients were allocated into case and control groups, respectively, based on death or alive until 28th day after birth. Data were analyzed with SPSS19th, and presented with descriptive statistics, Fisher’s exact test, chi-square, T tests and multivariate regression analysis. From 172 neonates, 54 were included in the case group and 118 in the control group. Birth weight and gestational age of the subjects, respectively were 1549.54(±635.42) g and 31.46 (±3.35) weeks. Antenatal antibiotics (OR: 0.3) had a protective effect. Maternal diabetes, preeclampsia, maternal RH and blood group, were the most effective maternal factors. Birth characteristics, such as crying, breathing, cyanosis, tonicity, cord status, and neonatal resuscitation in the delivery room and neonatal clinical findings at the time of admission including apnea, bradycardia, gasping,hydrops, ascites, and IUGR were the most influential factors (p<0.05). Gestational age (r=0.718), height (r=0.673), head circumference (r=0.608), and 5th minutes Apgar score (r=0.662) had the highest correlation with the final prognosis. According to the multivariate regression analysis bradycardia at admission time, maternal diabetes, maternal Rh, gasping at the admission time, tonicity in the delivery room, at birth crying, birth length, gestational age, birth weight remained in the premature neonates mortality estimation equation. The results of this study addressed increasing and protective perinatal factors against premature infant’s mortality.

Abstract: Separation is one of the most important steps in a chemical process so that a major part of energy is used for separation, concentration and purification. Fro the same reason, considerable work has been done to improve traditional processes and develop the savings technologies in regarding energy usage. Because of complexity and high cost of current processes, membrane separation technology has been recently examined as a good alternative. Membrane distillation (MD) has been taken into consideration as a new membrane distillation process enables to separate particles as tiny and petite as 0.1-7nm this process functions in low temperature between 30-90ºC that needs little source of energy besides high economic benefit. In membrane distillation (MD) process a hydrophobic membrane is utilized in contact with an input food solution. The base is on vapor-liquid equilibrium. In this paper, while describing membrane distillation, the parameters influencing MD as well as the laboratory system used were studied.

Abstract: Arictum lappa is extensively used in traditional Iranian medicine to treat upper respiratory infections and pneumonia in Iran as well as other countries. The objective of this study was to determine the cytotoxic effect of the aqueous extract of the roots of the plant Arictum lappa against endothelial human bone marrow cells (line k562) and human lymphocytes as a model of cancerous cell and normal respectively under different concentrations using the MTT assay. Percentage cell viability of cell lines were carried out by using Trypan blue dye exclusion technique MTT assay was used to evaluate the reduction of viability of cell cultures in the presence and absence of the extract. The absorbance was measured at 570 nm immediately using an ELISA reader. The results showed that the extract, exhibited marked cytotoxic effect on the k562 cell line and lymphocyte at a maximum concentration of 10 mg/ml culture medium. In fact at the highest concentration tested (10 mg/ ml culture medium) with a 24-hrs incubation period, A. lappa extract resulted in 96% (in average) inhibition of cell proliferation in both lymphocyte and k562 cells. Therefore this plant could be considered as potential source of anticancer compounds. Further studies are necessary for chemical characterization of the active principles and more extensive biological evaluations.

Abstract: The purpose of this study was to investigate the role of pre pregnancy body mass index (BMI) and gestational weight gain on pregnancy outcomes. Material & Methods: This study was prospective cross-sectional study. Subjects consisted of 1351 pregnant women who referred to childbirth to Besat Hospital in Sanandaj (the capital of Kurdistan province in the West of Iran). Subjects were chosen based on three factors: singleton term pregnancy, having medical records, and referring to the health care center up to the 12th week of pregnancy. Data collection was done through questionnaires. Results: The incidence of overweight (BMI>26) was thirty-eight percent. Investigating the effect of BMI on maternal complications and specifying odds ratio showed that chance of maternal complications in subjects with an BMI of 26.1 29; (CI = 95%; 0.58 3.16) is 1.36 times higher than, in those with a normal BMI and for women with BMI >29; (CI95%; 1.05 2.99) is 1.77 times more than normal BMI. Furthermore Study showed that the odds ratio for neonatal complications among women with BMI 26.1 29; (CI =95%; 0.40 3.84) is 1.25 times higher than women with normal BMI and for women with BMI>29; (CI95%; 0.25-2.23) is 0.75 times more than normal BMI. Chi-square test proved a significant statistical relation between childbirthmethod and BMI (P < 0.05). Conclusion: The results of the study showed that weight and BMI before pregnancy as important factors affecting maternal and neonatal complications.

Abstract: An analytical analysis of the roller length of a hydraulic jump is presented in this article. An important feature of a hydraulic jump is its roller (or recirculation zone), which plays an important role in dissipating of the energy of a supercritical flow in an open channel. When the flow routine changes in the downward flow, conjugate depths are created and jetting happens at this time. The beginning of the jump or the toe of the jump can easily be fixed as the mean position of the oscillation at the abrupt rise of the water surface. But there has not been any general accord to the location of the end of the jump and it has become a controversial issue. According to experiments and different slope values, some empirical formulas have been offered to specify length of the roller. Whereas there is not much investigation about the determining the roller length of a hydraulic jump, we have done an experimental study to represent the formula to estimate the roller length. Computed roller length is compared with calculated roller length of other researchers gained by different formulas. The roller Length depends on the critical depth which had been determined by using the Buckingham's theorem (pi theorem) in the represented article.

Abstract: SMEs are always in the forefront of economic policy debate, and governments consider them to be one of the engines of growth in developing countries. Customer satisfaction is a fundamental determinant of long-term consumer behavior. Customer satisfaction has gained very much attention in the last few decades in all areas of production. In an increasingly competitive and dynamic environment, greater attention is continuously paid to customer relationships and satisfied customers. Employee’s customer orientation is an important antecedent of their perceived empowerment. Literature on innovationin dicates that over the last two decades, there has been a systematic and fundamental change in the way firms undertake innovatory activities. In particular, there has been a tremendous growth in the use of external networks by firms of all sizes .Innovation is seen as a process which results from various interactions among different actors. How small and medium-sized enterprises (SMEs) effectively internationalize and achieve greater firm performance is an important question. SMEs play an increasing role in international trade and economic growth. Advances in information technology and globalization are leading to SMEs that are more active in international markets than ever before.

Abstract: Enterprise development is almost universally promoted in developing countries, and is often justified on the grounds that the emergence of entrepreneurs is an important mechanism to generate economic growth. Small and Medium Enterprises (SMEs) play a vital role in the economy of Iran. Human resource management (HRM) is seen as crucial for innovation and firm performance in Iran. Effective management of human capital might improve market performance of firm, and the impact of HR on organizational outcomes might improve organizational performance. Employees who have needed knowledge, skills and abilities required for individual performance contribute more to business results such as sales, market share, profits, quality of products and new product development.

ABSTRACT: Undoubtedly, investigation of each phenomenon and social behavior in a systematic approach reflects its scientific nature. In the process of rapid change that has taken place on the context of the knowledge-based economy, due to nature of the systematic approach, creativity and entrepreneurship have been founded as two really valuable powers. The Iranian government has designed programs, in order to increase the level of student’s entrepreneurship ability; unfortunately the programs were not successful due to lack of consideration about the Iran’s cultural environment and obviously because of the absence of systematic approach. Entrepreneurship culture can be investigated in both the personality and social environment. This articles aim is to examine the influence of personality traits on entrepreneurship level of the society. The current research has been performed based on 4 major hypothesizes “correlation between personal compatibility circumstances and success, systemic approach, the control locus and risk taking ability”. The research method is descriptive and in order to examine the researches hypothesis, 477 of self-employed students from 3 university units, have been selected according to the stratified random sampling method, to fill up the questioners.

Abstract: Current dwelling conditions in Iran especially in large residential projects are far from desirable. The purpose of this article is to determine and define a general and overall perspective for making Iranian residential units more desirable within a practical framework such as public participation. The objective is to use a descriptive and qualitative approach in the development of a practical model with three variables. These variables are public participation, architectural quality, plus residential quality and desirability. This article relies on descriptive and qualitative approach to develop a model for understanding logical relationships among effective factors in public participation and satisfaction. This article defines the role of public participation in the process of residential unit construction under current circumstances of Iran. It uses Maslow’s hierarchy of needs to relate participation models with various levels of residential quality and public satisfaction. The last part of this article shows that public participation and people-oriented architecture are the missing factors in achieving residential quality and desirability in the present circumstances in Iran.

Abstract: A field experiment was carried out in 2011-2012 season at 5 kilometers northeast of Behbahan in order to investigate the effect of Nitroxin Biofertilizer, Vermicompost, and Nitrogen on vegetative and reproductive characteristics of stock (Matthiola incana L.). The study is of factorial experiments type which has been laid out using Randomized Complete Block Design (RCBD) with 4 replications. The studied factors include use of Vermicompost at three levels (0, 1, and 0.5 kg.m-2), use of Nitroxin at three levels (without inoculation, with seed inoculation, and with seed inoculation along with irrigation water), and use of Nitrogen at three levels (20, 30, and 40 gr.m-2).The studied traits were diameter and length of blooming stem, diameter and length of inflorescence, and number of florets on inflorescence. Seeds were cultivated on September 29th 2011 and the flowers were harvested on February 4th 2012. Results show that the effect of various levels of Vermicompost, Nitroxin, and Nitrogen use on vegetative and reproductive traits of the flower is significant. The diameter and the length of blooming stem, the diameter and the length of inflorescence, and the number of florets on inflorescence are influenced by Nitrogen and Vermicompost (P<0.01).Use of Nitroxin has a positive impact on vegetative traits of stock (Matthiolaincana) so that the maximum height (54.89 cm) belongs to the treatment of “use with seed inoculation along with irrigation”and the minimum height (51.80 cm) is observed in the case of “use without inoculation” treatment.The effect of studied factors on the number of leaves is not significant. The maximum length of inflorescence is gained when using 0.5 kg.m-2 of Vermicompost along with Nitroxin in the case of “use with seed inoculation” treatment, whileits minimum amount is observed when 20 grams of Nitrogen fertilizer is used without use of Vermicompost and Nitroxin. On the other hands, a significant and positive increase in thickness of inflorescence is witnessed as use of Vermicompost is raised. There is no statistically-significant difference between two Vermicompost using levels of 0.5 kg.m-2 and 1 kg.m-2.Among the studied traits, the trait of floret number has the greatest correlation with the inflorescence diameter and length. According to the result, use of 30 grams of Nitrogen and 0.5 kilograms of Vermicompost in addition to use of Nitroxin withseed inoculation along with irrigationis recommended.

Abstract: The main objective of this paper is to investigate the feasibility of establishing suggestion system in Ardabil Islamic Azad University, Iran. Suggestion system is the customary method for transferring information and opinions to a higher level in an organization. The suggestion system may be a positive and helping power in the establishment of cooperation among employees. On the other hand the use of suggestion system can be a good replace for team building in an organization. The widespread use of suggestion system indicates its importance in participation. Especially by utilization of modern techniques and methods and by ever-increasing corrections and revisal of methods, schemes and forms its importance becomes clear more than ever. Research population is all of the employees and members of scientific boards in Ardabil Islamic Azad University. With regard to the selected formula for sample volume we choose 100 subjects from among the population (N=400). For data collection we design a questionnaire, which includes 5 general and descriptive questions and 20 questions about the effective factors on the feasibility of establishing suggestion system. Moreover, we prepare another questionnaire with 16 questions about the viewpoints of selected samples in relation to their jobs. Then we distribute these two questionnaires among samples and at the end we collect 95 completed questionnaires. We support the validity of questionnaire by consulting with members of scientific board who are experts in the field. We achieve to the reliability of 0.712 by the coefficient of Cronbach alpha, which is an acceptable coefficient. We use descriptive statistics for data analysis and classification, and for preparing diagrams and frequency tables. We obtain measures of central tendency and measures of variability for every variable. Then by means of inferential analysis, we analyze research hypotheses and answer to the questions. For analyzing research questions and hypotheses we also use Pearson’s correlation coefficient, and the obtained results confirm the feasibility of establishing suggestion system in Ardabil Islamic Azad University.

Abstract: Aim: This study aimed to detect changes in calcium, magnesium, potassium, sodium and chlorine levels in male and female footballers before, immediately after and 1 hour after aerobic exercise and to compare the mineral levels detected after the exercise by taking the gender into account. Method: Blood samples were taken before, immediately after and 1 hour after a 20-meter shuttle run test. Macro elements were detected by using the plasma emission spectroscopy method, and the significance level was accepted as P<0.05. Findings: A statistically significant difference was not observed in macro element levels in male and female footballers before, immediately after and 1 hour after the training. In females, the chlorine level in all three periods and the potassium level 1 hour after the training was found higher than males. Conclusion: It is thought that the duration of exercise does not cause a loss of liquid which may result in liquid imbalance; and the haemostatic balance which is strongly controlled by the body prevented the mineral levels from changing after the aerobic exercise.

Abstract: The design of a counterfort retaining wall is similar in many respects to that of a cantilever retaining wall as far as computing overturning and sliding stability, bearing capacity, and soil pressure beneath the base slab are concerned. The retaining-wall computer program in the Appendix can be used to obtain the wall stability, bearing capacity, soil pressure, and toe shear and moments for a counterfort wall.

Abstract: The finite-element (FE) method can be used to analyze a braced excavation. Both the finite element of the elastic continuum and the method of the sheet pile/beam on elastic foundation computer program in the Appendix can be used. Both these methods will be briefly discussed, with some of the limitations and disadvantages of each presented. Either method can be used for stage construction and work best in an interactive computer environment. The methods can be used for either braced (struts and/or rakers) or tieback construction. Both methods have best application for making rough predictions of expected field performance in terms of wall movements and ground loss.

Abstract: It is necessary for the foundation engineer to classify the site soils for use as a foundation for several reasons: l. To be able to use the data base of others in predicting foundation per­formance. 2. To build the geotechnical engineer's data base in the "art" application of design. 3. To maintain a permanent record which can be understood by others should problems later develop and outside parties be required to investigate the orig­inal design. Normally the Unified Soil Classification system (Table 2-1) with slight modi­fications is used in foundation design work. For example, in much foundation work it is academic whether a sand is well or poorly graded, but its density and the presence of gravel are of considerable interest. Whether a fine-grained cohe­sive soil is actually a clayey silt rather than a silty clay is not as important as identifying its strength and settlement characteristics

Abstract: It is a legal necessity when new construction is begun in a developed area to provide protection to the adjacent existing buildings when excavation in the new site is to any depth which may cause loss of bearing capacity, settlements, or lateral movements to existing property. New construction may include cut-and-­cover work when public transportation or public utility systems are installed below ground and the depth is not sufficient to utilize tunneling operations. The new construction may include excavation from depths of 1 to perhaps 15 m or more below existing ground surface for placing a "shallow" foundation or a mat, or to allow placing of one to three or more basements and subbasements. This type of work requires installation of some kind of system of retaining structure termed a cofferdam, braced sheeting, or slurry wall together with a means of holding the retaining structure in position. The retaining structure may be constructed of one of the following: I. Sheetpiling (steel, concrete, or wood). 2. Soldier beams (or piles) with or without lagging 3. Drilled-in-place concrete piles (or piers). 4. Concrete poured in a cavity retained with slurry.

Abstract: This presents methods to analyze and design cantilever and anchored sheet-pile structures. Types of materials used for sheet piles are also given as background for this chapter and the following chapters, which consider other foundation structures built with sheet piling. This will present briefly the classical methods of analyzing cantilever and anchored sheet piles, then proceed to the finite-element method, which has been shown by the author [Bowles (1974a)] to be the most rational method of analysis of sheet-pile walls. This method can be extended to obtain the best currently available method of analyzing braced excavations, as will be shown. The finite-element is quite similar to the finite-difference (sometimes called beam-column) method used by some organizations. The finite-element method has the advantage over the classical methods of directly applying "moment reduction" during the analysis and of obtaining the deflections and bending moments at the nodal points of the wall. The classical methods made simplifying assumptions and implicitly assumed dredge-line deflections were zero, and the moments computed were, generally, too large and required moment reduction for design. The finite-element procedure also gives directly the soil pressure required for wall stability for comparison with the bearing ability of the soil.

Abstract: Background & Objectives: The studies indicate that environmental, genetic, environmental, nutrition and physical activity can factors affect bone status. In this study, bone mineral density (BMD) of lumbar spine in active and in-active women post menopause was compared. Materials and Methods: This study was of comparative post-occurrence type. 24 of active and in-active postmenopausal women from Bojnourd city were volunteered in this study that at least 3 years and/or maximum 7 years have passed from their last menstruation. 12 of Active women with mean age: 54/58±1/93 years and BMI: 26/45±1/77 kg/m2) and 12 in-active women with mean age: 54/83±2/21 years and BMI: 25/41±1/46. Active women were involved in walking training program, 3 sessions per week (1 hour per session) for at least 3 years. Subjects BMD of lumbar spine were measured by the DEXA device. SPSS software ver-16 was used to analyze data. Independent t-test performed at significant level (P0.05). Results: The results of this study showed that BMD of the lumbar spine in active postmenopausal women was significantly higher than in-active postmenopausal women (P<0.05). Conclusion: Regular walking as the body weight bearing activity contributes to increasing BMD of the lumbar spine by increasing work load on bone. Thus, walking as low–cost and most effective exercise can be used to prevent osteoporosis at the time of menopause.

Abstract: The primary and secondary consolidation settlements, of saturated cohesive soils are generally estimated using consolidation theory. 'A consolidation test is per­formed to obtain a compression parameter for the amount of settlement and a consolidation parameter for the settlement rate estimate. The over consolidation ratio OCR can also be determined from this test. The test is performed on an "undisturbed" sample which is placed in a consolidation ring available in diam­eters ranging from 45 to 115 mm (1.8 to 4.5 in). The sample height is between Z(1 and 30 mm (0.75 and 1.5 in); 20 mm is the most commonly used thickness to reduce test time. The larger-diameter samples give better parameters, since about the same amount of disturbance is developed for any size sample, with the relative effects less for the larger samples. The most common test diameter is 64 mm (2.5 in), since this best balances the costs of sample recovery and disturbance effects. Tube diameters larger than 76 mm may result in a premium charge for the sample-particularly if a larger borehole must be made.

Abstract: With population growth and land use developments as well as higher per-capita vehicle ownership in metropolitans, travel demand and traffic volume has been increased on urban streets. Traffic lights are effective to make order in movements in intersections to control vehicle movements. However, further increasing the flow through the intersection, if inappropriate settings for the lights, the amount of delay for most vehicles will be increased and as a result, their effectiveness will be lowered. This will have consequences like high fuel consumption and air pollution. Having syncronized traffic lights in a path, so called Green Wave, one can pass all traffic through it in a shorter time and observe significant decline in air pollution and fuel consumption. A case study undertook on three signalized intersections in Jomhuri Street between Vali-asr and Ferdowsi which have suitable distances and requirements for Green Wave. The results indicate 27% more decline in air pollutant emissions and also 20% more decline in fuel consumption in selected pass ways than before synchronization.

Abstract: The aim of this study is to assess aerobic, anaerobic and performance indexes changes after a short period of coenzyme Q10 Supplementation in soccer players. 16 soccer players (Weight 57.1±20.72, height 171.4±4.92, and age 22.30±1.41) randomized and divided into two groups. Where supplement group (N=10) consumed CoQ10 supplement (300 mg/day) and placebo group (n=6) consumed placebo. Both of them practiced for 4 weeks and each one 90 minutes. After that, supplement group started to consume CoQ10 in amount of 300 mg/day for one month. Findings has been showed that 4-week supplement consumption caused significant changes in VO2max and performance in soccer players, while this intervention did not result in significant effect in body composition, maximum running speed, peak anaerobic power and fatigue index. The major findings of the present study were that 4-week of CoQ10 supplement consumption in college soccer players led to increase aerobic power and performance in high intensity aerobic interval test. From the other point of view, these variations were not significant in placebo group. We can conclude that although increase in maximum running speed (vVO2max) was not significant, four weeks of CoQ10 supplement consumption may increase in maximal oxygen consumption and performance in college soccer players. Finally, in this case consumption of this supplement could improve player’s performance in competition conditions.

Abstract: E-Government initiatives help in providing governmental services to citizens at their doorstep. Different financial, organizational, and political constraints hinder in successful adoption of such initiatives. As a result E-Government adoption is not uniform in every country resulting in digital divide. In this article we examine the E-Government implementation barriers in Pakistan. In order to understand the hindrances in adopting E-Government initiatives in Pakistan we carried out an empirical study. In our study we found that in Pakistan mainly E-Government services are used for information broadcasting, whereas transaction based services are scarce. We have discussed different governmental barriers and present some guidelines to solve these obstacles in local context.

Abstract: Ownership structure affects managers’ enthusiasm; hence, efficiency of organization is one of the most important issues in organization. Demonstration of ownership structure, its kind, and its optimal composition is a way to control. Thus, we aim to investigate the relation between ownership structure and stock return in companies which are listed in Tehran Stock Exchange (TSE). Following, we investigated the relation of two ownership structures and stock returns. Statistical samples were 106 companies during 2008 and 2012. befactor model was used to expose our variables relations. In our model, returns used as (dependent variable) and managerial ownership percentage and institutional ownership percentage used as (independent variables). Our results indicate that there was a significant relation between dependent and independent variables. Adhesion tests represented that relationship of returns to managerial and ownership respectively was positive and negative.
