Abstract: Lipases of Trichoderma viride were precipitated from the cultural medium with different methods. Acetone precipitation at 60% saturation point was the best one. The enzyme was partially purified by gel filtration chromatography using sephadex G-75. The enzyme was found to be of 25.2 KDa. The maximal activity has been obtained at high temperature (60C) but the enzyme tolerates temperature up to 45C. Also, it is characterized by its high stability and activity at the acidic pH values. The maximum activity has been maintained at pH 3 (49.1 unit/ml), with 80% residual activity. Also, it was stable with enhanced activity in the presence of bile salts (124% residual activity was maintained even after 45 min. incubation with 6 mM sodium cholate). Also, lipase enzyme showed nearly 100% residual activity in presence of trypsine enzyme. The enzyme has been tested for its ability in the management of pancreatic exocrine insufficiency using L-arginine induced acute pancreatitis mice models. The enzyme has the ability to decrease the weight loss and enhance fat digestion in this case. The total lipid level in serum after fat diet was enhanced from 837.99 mg/dl, in case of acute pancreatitis group without enzyme supplying, to 949.7 mg/dl, in case of acute pancreatitis group supplied with the enzyme, and a total weight gain of +0.21 gm body weight has been reported after the enzyme supplying for only 4 days.

Abstract: Seeds of five cowpea varieties, Kaha 1, Dokki 331, Azmerly, Cream 7 and Giza 6, were exposed to different doses of gamma radiation at50, 100, 200 and 300Gy. Some growth parameters and yield components were measured in 22 M2 genotypes. Variation in seed protein electrophoretic pattern, RAPD and ISSR fingerprinting was scored to assess genetic variation among the M2 genotypes. T he gamma dose of 50 Gy resulted in an increase of growth parameters and enhanced yield components in the three varieties Dokki 331, Azmerly and Cream 7; while the dose of 100 Gy resulted in higher growth rate and yield in var. Kaha 1 and var. Giza 6. Analysis of seed protein profile indicated specific bands for each variety; two bands appeared only in control plants and two other bands appeared inM2 plants of exposed seeds. Seven RAPD primers produced 30 polymorphic and 30 monomorphic bands. Meanwhile, 54 markers including 45 polymorphic bands were produced by the nine ISSR primers. Gamma radiation induced more genetic variation in the genotypes of var. Kaha 1 and var. Dokki 331 compared to other varieties, as estimated by the cluster analysis of seed protein, RAPD and ISSR markers.

Abstract: Objectives: To estimate a period-percentage of non-emergency cases attending emergency department (ED) at King Fahd Hospital, Jeddah, KSA and to describe the pattern and outcome of those cases. Subjects and Methods: A cross-sectional study was conducted, taking a representative random sample of patients who attended the emergency department of King Fahd Hospital in 2012. A checklist was completed using the file data in ED archive. This list contains socio-demographics, medical status, complaints, emergency level and outcome. The Canadian emergency department triage and acuity guidelines (CTAS) were used to assess the emergency level. Results: We analyzed 388 patients’ files, of which (82.7%) were adults, (71.9%) were Saudis and (69.1%) were male. Only (7.9%) of the patients arrived in ED by ambulance. Trauma and RTA were the main causes of attending ED (24.5%), followed by fever (12.4%) and GIT complaints (11.9%). Based on the CTAS classifications, (42.3%) of the patients were class V, (22.7%) class IV (less and non urgent), and only (3.1%) in class I (Resuscitation). Our study revealed that (22.7%) of the patients needed admission to hospital. Conclusion: Inappropriate utilization of the ED is a common practice in the Saudi community. Most of the patients come with minor self-limiting complaints. Concept of “fast track” units should be introduced in ED to ensure the expeditious management of low acuity patients.

Abstract: Background: The non-steroidal anti-inflammatory drug indomethacin (IND), utilized in the treatment of inflammatory disorders, has been found to induce liver disorders in both animals and humans. Its administration in a high dose causes hepatic toxicities and results in liver cell deaths by activating multiple stress pathways. Objectives: This study was conducted to investigate the effects of thymoquinone (TQ) on indomethacin-induced hepatotoxicity in rats. Study design: Male adult albino rats were divided into 4 groups: Group I: control non-treated group; the rats were treated orally with normal saline, Group II: TQ-treated (TQ) group; the rats were treated with TQ in the dose of 10 mg/kg/day orally, Group III: single high dose IND- treated (SHDI) group; the rats were treated with IND in the dose of 25 mg/kg once orally at the end of the duration of normal saline treatment, and Group IV: concomitant TQ- and IND- treated (CT/I) group; the rats were treated orally with TQ in the dose of 10 mg/kg/day, and then with IND in the dose of 25 mg/kg once at the end of TQ treatment. The treatment was for 4 weeks for all groups. At the end of the experiment, serum alanine transaminase (ALT), aspartate transaminase (AST), albumin, total antioxidative capacity (TAC) were measured in all rats. Agarose gel electrophoresis for DNA (DNA analysis) for rat’s liver tissue was investigated also after sacrificing the rats. These parameters were expressed as the means of the effects ± SEM. Results: There were significant (P < 0.001) decrease in serum ALT and AST. and significant (P < 0.001) increase in serum TAC and DNA analysis between CT/I group and SHDI group. Albumin was not significantly changed (P > 0.05) between CT/I group and SHDI and control groups. Conclusion: These findings suggested that TQ is strong protective agent against IND-induced hepatotoxicity in rats. The collective data demonstrated that TQ has the potential to scavenge oxidants and decrease apoptotic changes and revealed a possible protective target mechanism for the damaging effects of IND on liver in rats.

Abstract: Objective: The present study was carried out to investigate the effect of oral administration of aqueous extract of Chamomile capitula for 4 weeks on hepatotoxicity induced  to rats by herbicide 2, 4-Dichlorophenoxy acetic acid (2, 4 D). These effects could be explored by measuring body weight gain, feed efficiency ratio and relative weight of the liver. Serum levels of liver enzymes; aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP); albumin, total protein, total bilirubin, lactate dehydrogenase (LDH) enzyme and antioxidant enzymes; glutathione reductase (GR) and superoxide dismutase (SOD) were determined. Methods: Thirty six male Wistar rats were allocated into six groups as follows: - Group1: negative (normal rats) control; Group 2: positive (hepatotoxic) control given dose of 75 mg/kg b.wt., of 2, 4- D for 4 weeks; Group 3: Positive (hepatotoxic) control given dose of 150 mg/kg b.wt., of 2, 4-D for 4 weeks; Groups 4: given orally Chamomile capitula extract in a dose of 500 mg/kg b.wt., alone. Groups 5 and 6: given combination of Chamomile capitula extract with either the accumulative doses of the 75 mg/kg b.wt, or the 150 mg/kg b.wt., of 2, 4-D for 4 weeks. Results: The results showed that oral administration of Chamomile capitula extract to hepatotoxic rats for 28 days significantly decreased the elevated serum levels of liver enzymes (AST, ALT and ALP), total bilirubin and lactate dehydrogenase enzyme and  positive groups. Levels of antioxidant enzymes glutathione reductase and superoxide dismutase were significantly increased as compared to the control positive groups. Conclusion: The results suggest that Chamomile capitula aqueous extract induces potent hepatoprotective and antioxidant effects in 2, 4 D - hepatotoxic rats. This study recommends that intake of Chamomile capitula extract as a herbal tea may be beneficial for patients who suffer from liver diseases and oxidative stress antioxidant enzymes.

Abstract: In the present study an attempt has been made to investigate the potential allelopathic effects at different concentrations (0, 10, 25, 50 and 75%) of water extract of roots and leaves of Heliotropium bacciferum Forssk. on seed germination, seedling growth and biochemical constituents changes Oryza sativa L and medical plants Teucrium polium L. The results showed that the roots and leaves extracts of H. bacciferum caused a general phytotoxic effect on seed germination and seedling growth of O. sativa and T. polium at all concentrations. It was noticed that the germination in both tested plants was delayed for one and two days at the highest levels of extract (50 and 75%). The degree of seed germination inhibition was higher in leaf extract more than root extract of heliotrope plants. Also, O. sativa seeds were more affected at different extract concentration than T. polium. With respect to the internal metabolites, a gradual increase in the proline content, decrease in the chlorophyll content and consequently the soluble sugar content is proportional to the increase the concentrations of water extract of roots and leaves of heliotrope. Aqueous extract of heliotrope leaves induced more inhibitory effects than aqueous extract of heliotrope roots. A greater inhibitory effect was observed on T. polium as compared with O. sativa. Consequently, the aqueous extracts from H. bacciferum have allelopathic potential and should be evaluated as an allelopathic species, presenting arisk to seed germination and seedling growth of crops or weeds.

Abstract: Introduction: Mild renal dysfunction is an important cardiovascular risk factor predispose to coronary heart disease. In recent years natriuretic peptides have become promising candidates in the early detection of cardiovascular disease (CVD) such as heart failure. In end stage renal disease (ESRD) patients, the clinical benefit of N-terminal probrain natriuretic peptide (NT-proBNP) measurements has not been well established. Aim of the study: Is to evaluate the role of serum NT-proBNP levels in diagnoses and to detect the progression of left ventricular dysfunction and left ventricular mass in a sizable cohort of stable patients on chronic HD without clinical signs of progressive heart failure. Patients and methods: This study was conducted on 100 persons, 55 were known as ESRD patients on regular conventional hemodialysis (HD) [Dialysis group] and 25 patients with chronic kidney disease(CKD) not on HD [CKD group] in addition to 20 healthy volunteers [control group]. All participants were thoroughly interrogated and examined clinically and were subjected to plasma NT-proBNP level and transthoracic echocardiography at baseline and after six months. Results: Mean NT-proBNP showed significantly higher mean in dialysis group (252.88 ±125.193 fmol/ml) compared to the CKD group(168.266 ±134.881 fmol/ml[P=0.007], and the control group(9.075±6.707fmol/ml)[P<0.001].There was a significant strong inverse correlation between NT-proBNP and ejection fraction(EF) (P<0.001). There was also a strong positive correlation between NT-proBNP and change of EF over six months (∆ EF) (P<0.001). Also there was a significant strong positive correlation between NT-proBNP and left ventricular mass (LVM) & LVM index(LVMI) and change of LVM & LVMI over six months (∆ LVM) (P<0.001). Conclusion: The study recommended that plasma NT-proBNP assessment is an easy non invasive test and should be monitored in HD patients owing to its close relation to LVM, systolic dysfunction and cardiovascular morbidity and mortality in this population. Rising NT-proBNP levels may reflect worsening ventricular stress and may help earlier diagnostic and therapeutic strategies.

Abstract: Web-based Blood Donation Management System is a management system website that enables individuals who want to donate blood to help the needy. It also enables hospitals to record and store the data for people who want to communicate with them, and it also provides a centralized blood bank database. The system is developed by using HTML, PHP, and MySQL as a database system to manage and store the data. The Waterfall Methodology, which is the traditional version and the classic approach of a system development life cycle, is used to develop and build the web-based blood bank. The system targets three types of user: the public who wants to donate blood, the recipients who need the donated blood, and the hospitals who that work as an intermediary to manage the communication between the donors and recipients. The main objectives for developing the website is to educate the community on the benefits of blood donation, develop a Web-Based Blood Bank System to manage the records of donors and recipients, and encourage voluntary blood donation, easily accessing any information about blood type and the distribution of the blood in various hospitals in Jeddah, based on the hospital needs.

Abstract: To assess the environmental quality in the Lake Van, Chalcalburnus tarichi, the only vertebrate and an endemic carp species of this lake basin, samples were collected from the lake, and their livers were examined histologically for this purpose. Histological alterations were recorded and evaluated semi-quantitatively based on the liver lesion categories and their severities. According to the results, five of a total of forty samples displayed normal (healthy) liver architecture, but the others displayed various histopathological alterations, including hepatocyte vacuolization, fatty degeneration, increase in melanomacrophage centers, necrosis, infiltration, congestion, fibrosis, single cell necrosis, bile duct alterations, glycogen depletion and nuclear pleomorphism. Liver index values were calculated and found to be changed between 2 and 50 (≤4 for fish with normal livers (FwNL) and ≥8-50 for fish with histopathological livers (FwHL). We also investigated oxidative stress biomarkers, lipid peroxidation (LPO) and antioxidant enzymes (superoxide dismutase (SOD) and catalase (CAT)) in FwHL as compared with FwNL. LPO and CAT were found to be significantly higher in FwHL, indicating increased oxidative stress. The results revealed that the observed histological and biochemical alterations in the livers of C. tarichi reflect the effects of environmental stressors present in the lake water causing pollution.

Abstract: Increasing the use of antibiotic is harmful to human health, ecosystem and environment and enhancing incidences of drug-resistant pathogens. Medicinal plants have recently received the greatest attention to find naturally occurring substances with therapeutic value. Coriandrum sativum, Crocus sativus and Nerium oleander were collected, dried and extracted with methanol, ethanol, n-butanol, chloroform, ethyl acetate or water. The obtained extracts were assessed for antibacterial activity against Methicillin-resistant Staphylococcus aureus (MRSA). The methanolic extracts were the most active, thus they were screened for their antimicrobial activity against some different genera of bacteria using agar well diffusion method. The tested bacteria included resistant bacteria to one or more antibiotics. The obtained extracts exhibited considerable inhibitory effects against all the tested bacteria and the less inhibited bacterium was Salmonella. The minimum inhibitory concentrations (MIC) of the methanol extracts ranged from 50-100 µg/ml. No toxicity for C. sativum, C. sativus was found using Artimia salina as test organism whereas acute toxicity was recorded for N. oleander. The extract of C. sativus showed excellent antitumor activity against Ehrlich ascites carcinoma.

Abstract: The fibroblast cell line from the Wenchang chicken was successfully established by the attachment culture method and the cryopreservation biotechniques. Cell morphology, dynamic proliferation and any contamination present were tested, the karyotype, levels of isoenzymes of lactic dehydrogenase and malic dehydrogenase were analysed. Results showed that the cells were morphologically consistent with fibroblasts, and the growth curve was sigmoidal with a population doubling time (PDT) of 48 h. Karyotyping and G-banding indicated a total chromosome number of 2n=78; Isoenzyme analysis confirmed that there was no cross-contamitation in the culture. The three types of fluorescent protein extro-genes appeared to be expressed effectively with high transfection efficiency between 15.6% and 38.6%. The results indicate that the quality of the cell line meet the quality requirements of the ATCC (American Type Culture Collection).

Abstract: Ginger (Zingiber officinale Roscoe.) is an important spice crop in Bangladesh as well as in all over the world for its economical and medicinal values. A measure of the existing genetic diversity is essential for planning a meaningful breeding strategy. Moreover, assessment and characterization of genetic diversity of the available germplasm is important to know the source of gene for particular trait of interest. The present investigation was undertaken to assess the genetic diversity among eight ginger genotypes using RAPD markers. A total of 16 distinct DNA fragments ranging from 100–1000 bp were amplified by using three selected primers of which 10 (62.50%) were polymorphic. BARI ada-1 was more homogenous than others and Syedpuri was found less homogenous showing the low intra-variety similarity value (75.56). the genotype ‘Syedpuri’ was found as more diversified from the viewpoint of lowest intra-variety similarity index value, highest gene diversity, proportion of polymorphic loci and highest level of genetic variation. The cluster analysis indicated that the eight genotypes were grouped into two major clusters. ‘Indian’ alone formed the first major cluster while the second major cluster had seven genotypes and was divided into two minor clusters. China and Sherpuri genotype pair was very close to each other with the lowest genetic distance (0.03). On the other hand, Indian and Syedpuri pair was more distant to each other with the highest genetic distance (0.55). RAPD analysis revealed a considerable level of polymorphism among the studied genotypes. The genetic variation thus detected has significance for ginger improvement programs.

Abstract: Osteoporosis is a skeletal disorder characterized by low bone mass and loss of bone tissue that may lead to weak and fragile bone. It is affected by numerous factors, including age, dietary factors, lack of exercise, menopause, underweight, excessive alcohol consumption and cigarette smoking. The aim of the present study is to investigate the influence of cigarette smoking on Bone mineral Density (BMD) and examine the relation between cigarette smoking and vitamin D among men. A total of ninety-six males, aged between 32–50 years, were recruited and divided into 4 groups according to their smoking status: non smoker (n=26), light smoker (n=18), moderate smoker (n=26) and heavy smoker (n=26). Participants visited the Center of Excellence for Osteoporosis Research (CEOR) at King Abdul Aziz University and completed a questionnaire about medical history, lifestyle and smoking habits. Written informed consent was obtained from all participating men. Bone density was measured using dual-energy X ray absorptiometry (DXA) at three sites, the lumbar spine (L1-L4), femur neck and total hip. Serum Ca, PO4, Mg, iPTH, 25-OHD3, OC and CTx were measured. We found that bone mineral density at femur neck was significantly lower in light and heavy smoker groups compared to non smoker group (P< 0.05). BMD were positively correlated with body mass index (P<0.01) and waist to hip ratio (P<0.01) in heavy smoker group and negatively correlate with number of years smoked (P< 0.05). Nearly 69% of our study population had low serum 25-OHD levels (<25nmol/L). In the heavy smoker group, 80% had vitamin D deficiency (<25 nmol/L) compared with 46% in the non-smoker group. There were a significant negative correlation between serum 25-OHD and number of cigarettes smoked daily (P< 0.05) and PTH level (p<0.01) in heavy smoker group. Smoking was associated with reduced BMD in the heavy smoker group and the smoking duration (years) had a stronger effect on BMD than the number of cigarettes smoked daily.

Abstract: A field experiment was carried out to investigate the effects of prilled urea (PU) and urea super granule (USG) alone and their combinations with poultry manure (PM) on growth and yield of transplant Aus rice (cv. BR 21) and field water quality. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The treatments were T1: Control (no fertilizer), T2: (165 kg N ha-1 from prilled urea), T3: (119 kg N ha-1 from USG), T4: (82 kg N ha-1 from prilled urea + 3 t ha-1 poultry manure) and T5: (56 kg N ha-1 from USG + 3 t ha-1 poultry manure). The highest grain (3.19 tha-1) and straw yields (4.51tha-1) were obtained from treatment T5 (56 kg N ha-1 USG + 3.0 t ha-1 poultry manure) while the lowest grain (1.99 tha-1) and straw yield (3.38 tha-1) were recorded for T1 (control). Treatment T3 (119 kg N ha-1 from USG) performed better than T2 and T4 indicating the superior effect of USG over prilled urea. The N, P, K and S contents in the grain and straw and their total uptake were influenced profoundly due to application of PU, USG alone or in combination with poultry manure. In case of rice field water quality, the USG generated available NH4-N slowly but spontaneously over the entire growth period compared to prilled urea indicating a beneficial role of USG. The other properties of field water like pH, EC were also influenced by the application of prilled urea, USG and poultry manure. The overall results indicate that application of USG in combination with poultry manure was more effective in producing higher rice yield and at the same time reduce water pollution.

Abstract: A field experiment was conducted at the Bangladesh Institute of Nuclear Agriculture (BINA) farm, Mymensingh, Bangladesh, during the rain fed condition in July to December, 2011, with a view to study the performance of aromatic fine rice under different number of seedling hill-1. The experiment was carried out with four aromatic fine rice varieties (V1= BRRI dhan34, V2= Ukunimadhu, V3= Basmati and V4= Kataribhog) and four different number of seedling hill-1 (N1= one number of seedling hill-1, N2= two number of seedling hill-1, N3= three number of seedling hill-1 and N4= four number of seedling hill-1). The experiment was laid out in split-plot design with three replications assigning variety in the main plot and the four different number of seedling hill-1in the sub plot. Experimental result showed that aromatic fine rice varieties and number of seedling hill-1 individually had significant effect on the agronomic parameters except number of non-effective tiller hill-1, number of unfilled spikelets panicle-1, 1000-grain wt (g). The highest grain yield (2.32 t ha-1) was obtained in Kataribhog, which, was similar to Basmati (2.31 t ha-1) followed by Ukunimadhu. The highest grain yield was (2.31 t ha-1) with two number of seedling hill-1 which was statistically similar to three number of seedling hill-1 (1.96 t ha-1) but different from single number of seedling hill-1 and four number of seedling hill-1.The lowest grain yield were with one and four number of seedling hill-1 but straw yield (5.00 t ha-1) was significeantly higher with four number of seedling hill-1. Combined effect showed that two number of seedling hill-1 produced highest grain yield by all the variety. In later of number of four seedling hill-1 production of grain yield was decreased. BRRI dhan34, Ukunimadhu, Basmati and Kataribhog with two number of seedling hill-1 can be suggested in rainfed condition of Bangladesh.

Abstract: Objective: To retrospectively study the original lesion resection for the treatment of secondary epilepsy under the monitoring of electrocorticography (ECoG) during operations and discuss the value of intraoperative ECoG monitoring. Methods: By means of observing the treatment of 72 patients with secondary epilepsy, we analyzed the significance of intraoperative ECoG monitoring in the treatment of secondary epilepsy. Among the 72 cases, 15 patients were meningiomas, 28 were gliomas, 15 were cavernous hemangiomas, 5 were arachnoid cysts, 5 were post-traumatic changes, 2 were cholesteatomas and 2 were arteriovenous malformations. Results: There was no epileptic wave in all the studied patients revealed by the regular postoperative EEG. No death or new neurological dysfunctions were recorded following the surgeries. A follow-up investigation lasting from 1to 5 years revealed that there was no epilepsy recurrence in all the patients except for partial seizures in two patients. Conclusion: The monitoring of electrocorticography (ECoG) would significantly improve the efficiency of surgical management for the patients with secondary epilepsy.

Abstract: In order to identify the main reasons for the success and failure of IT projects in Saudi Arabia; we have analyzed the responses of three hundred and eight project managers to an online structured questionnaire. In addition to that, semi structured interviews were conducted with eight project managers. The nationalities of those project managers were various and they have worked either in public or private sectors in Saudi Arabia. This study has found common reasons for failure of IT projects in Saudi Arabia. Organizational culture, conflict of interest, and the instability and lack of clarity of the set of requirements were characterized as the most important causes for failure. Additionally, Critical Success Factors (CSFs) that should increase the project success were also enumerated based on the questionnaire responses and the interviews. Those included: clear statement of requirements, the project manager leadership, and soft skills.

Abstract: This paper investigated K-means Algorithm, a well known clustering algorithm. K-means clustering algorithms have some shortfalls and defects, and one defect is reviewed in this study. One of the disadvantages of k-means clustering algorithms is that they can produce clusters that do not always include all the correct components. It is due to the presence of the error rate during the clustering process. The purpose of this research was to decrease error rates in the k-means clustering algorithm and to reduce iteration of running this algorithm. A novel method is proposed to calculate the distance between cluster members and cluster center. To evaluate the algorithm proposed in this study, seven well-known data sets consisting of Balance, Blood, Breast, Glass, Iris, Pima and Wine data sets were used. This investigation revealed that the performance of K-means algorithms was increased and resulted in valid clusters and that it reduced error rates, run time and iteration.

Abstract: Flat Electroencephalography is a way of viewing electroencephalography signals on the first component of Fuzzy Topograhic Topological Mapping (FTTM), a model which was designed to solve neuromagnetic inverse problem. This novel method is well known for its ability to preserves the orientation and magnitude of EEG sensors and signals. However, this preservation renders Flat EEG to contain unwanted signals captured during recording from the surroundings. Consequently, its accuracy in depicting actual electrical activity inside the brain is affected. Present of artifacts would pose a serious problem if it is large. Thusly, this study will investigate the persistence of Flat EEG to surrounding “noises” from dynamic viewpoint by means of structural stability. Basically, it will be showed that Flat EEG in the presence of “noises” may still reflects the actual electrical activity inside the brain, if the contaminated Flat EEG falls within a class of dynamical systems.

Abstract: Utilizing available daylight in buildings is a crucial issue for reasons of energy-efficiency as well as improvement of occupant’s health and well-being. Anidolic Daylighting System (ADS) is a type of daylighting system that provides daylight in areas far from windows. This device concentrates daylight in a collector and transfers it to duct situated between collector and distributor, which then spreads this daylight to the inside of the building. The aim of this research is to determine optimum Anidolic duct shape and width which increases daylight illuminance into the interior of office buildings. The simulation model was designed in Integrated Environmental Solution IES<VE> software to perform daylight simulation experiments. Therefore, three configurations of designed duct shape with two duct lengths (12 and 20 meters) were simulated as duct shape variables. Three different duct width sizes were also evaluated. Results indicated that a rectangular shaped Anidolic with three meter duct width offers higher illuminance than the other simulated cases. For future study, other parameters can be carried out such as depth of duct, size of anidolic, collector and distributor of device.

Abstract: The article suggests a methodology of a quantitative estimation of the sustainability of the regional socio-economic systems (RSES). The special attention is paid to the role of the information, communication and innovation factors in these processes. To solve the objective of a quantitative estimation of the RSES sustainability the methodology of the calculation of the general integral index in the context of the following blocks was selected: 1) economic relations; 2) the social situation; 3) the institutional environment; 4) the innovative potential. The formation of the index was made on the basis of the methodology of the calculation of the HDI UNDP. The data of the statistical collections “Regions of Russia. Socio-Economic Indicators” for the period from 2003 till 2012 were used as the information source of the calculations. The selection includes 80 subjects of the Russian Federation. The data processing was performed with the help of the Microsoft Excel programme analysis package. The international practice and the frame of the multivariative correlation and regression analysis were used at the selection of the indicators for the calculation of the subscripts included in the general integral index of sustainability. The integral indexes of the sustainability for 80 subjects of the Russian Federation for the period from 2003 till 2012 were calculated according to the suggested methodology. The estimation of the received results has allowed drawing a conclusion that the sustainable development of the majority of the Russian regions has increased during the analyzed period. Also it is established, that the greatest contribution to process of the development was made by the economic (the average partial coefficient was 0.445) and institutional components (0.402); the low level of a social subsystem development (0.260) and the innovative activity (0.032) were noted.

Abstract: Today it is without any hesitations we can say about the especially responsible and difficult beginning of forming Kazakhstan historical science, studying of its «white spots» and scientific estimation of past achievements, major stages and events of national history, nor tuned here nor under whose subjective looks and estimations, leaning only on weigh complex of facts, exposing polysyllabic maintenance the history of people, contradictory character of development of events in the last centuries. Among the problems of historical science there is still a question of including Kazakhstan to complement of Russia, which has its beginning from times of activity of khan Abulkhair- the main initiator of joining the births of junior zhuz in the complement of empire. In recent soviet time this act was named as a «historical», «voluntarily joining», on the whole positive and progressive. With the use of words "absorption", "violent capture" and "colonization", the modern estimation has another point. A period of the emotional beginning in learning concrete historical events, which is typical for alteration years, when most of the people were deeply interested only by their own past, history, is departed. Today has come the time of sound scientific searches. Especially in the direction of objective and independent study of difficult pages of national history and delivering from vices of the former general allied history. "We must achieve, by learning justify," -considered the academician M.K.Kozibaev,-lessons to domestic history, to dethrone present myths, attain truth. Obviously, there is a special fixing and debt of the Kazakhstan historians".

Abstract: This article focuses on the processes of ethnic and cultural identification and self-identification, which the indigenous peoples of the North of Russia and Siberia, living in the Russian Federation, are currently going through. The post-Soviet cultural practices of preservation of ethnic identity of the small-numbered peoples of Siberia—the Kumandins and the Dolgans —are studied. The conclusion is made that there is not any state language policy aimed at preserving of the Kumandin language and Dolgan language. The Kumandins and the Dolgans have active processes of ethnic identification, but the post-Soviet cultural practices do not relate to these processes. Processes of ethnic and linguistic assimilation are accompanied by post-Soviet practices, where state policy does not increase and does not weaken the ethnic identity of the indigenous peoples of Central Siberia. In present time are developed and strengthened social stratum “national elites”, which are characterized by symbolic ethnicity. For modern ethnicity processes of Indigenous Peoples of Central Siberia are characterized by dual ethnic identity.

Abstract: This paper proposes a new method of detecting moving vehicles in traffic videos using the background subtraction method, morphological binary operations, and new detection zone technique. Firstly, this method extracts a background image from the video frames using the mode statistical method, wherein the background will be subtracted from subsequent frames to distinguish the foreground objects by using the background subtraction method. Secondly, the morphological binary dilation and erosion operations are used to refine the boundaries and the regions of the detected moving vehicles (foregrounds), and unwanted small objects will be removed from the background respectively. Finally, we adopt the concept of a switch electric circuit design SPST (Single-Pole Single-Throw) as a new method to detect and count the moving vehicles. Performance evaluation of the experimental results is encouraging in that it shows that the proposed detection method has an average precision of more than 0.92, an average recall of more than 0.97, an average f-measure of more than 0.94 and average accuracy of more than 0.99.

Abstract: In rings with involution, the concept of *-zero divisors is introduced and the relation with zero divisors in rings without involution is discussed. This definition, however, is compatible with the category of involution rings; since it preserves the involution. Moreover, closely related definitions; such as *-completely prime ideals and *- rings and *-cancellation law are introduced. Finally, *-prime and *-completely prime *-ideals are characterized using *-zero divisors.

Abstract: An experiment was conducted in the field, Department of Plant Pathology, Bangladesh Agricultural University, Mymensingh, Bangladesh to control the late blight of potato using biological agents. The experiment was carried out following factorial Randomized Complete Block Design (RCBD) with four replications for each treatment. Biofungicide treated seed tubers resulted lower late blight incidence and severity followed by Bavistin. Late blight incidence and severity was higher in control. The number of stem as well as highest plant height were recorded where potato tubers were treated with BAU-Biofungicide followed by Bavistin than untreated control. Moreover, BAU-Biofungicide followed by Bavistin treated potatoes resulted good effect on formation of the highest number and weight of tuber than untreated control. The highest tuber yield (5.30 t/ha) was recorded in BAU-Biofungicide in case of Diamant variety of Grade B in cut tuber that resulted 65.63% higher over control.

Abstract: Introduction: Diclofenac is one of the most frequently prescribed non-steroidal anti-inflammatory drugs (NSAIDs) and have been reported to cause multiple organs damage. Ginger extract has been used as an antioxidant and preventive agent against a number of diseases. Aim of the Work: This work aimed to study the possible histological and ultrastructural changes of liver induced by diclofenac treatment and to evaluate the possible protective effect of ginger extract. Materials and Methods: Forty adult male albino rats were divided into 4 main groups. Group I: served as control. Group II: received ginger extract orally in a dose of 250 mg/kg /day. Group III: animals received diclofenac intramuscularly at a dose 150 mg/kg /day. Groups IV: animals received ginger extract then diclofenac after two hours in the previous doses. The treatments were given for rats for 7 days, then, rats were sacrificed by ether anesthesia and specimens from liver were taken for light and electron microscopic examination. Results: Light microscopic examination of the liver treated with diclofenac revealed disorganized hepatic architecture. The affected lobules appeared with dilated congested central veins and blood sinusoids, vacuolated hepatocytes with dark nuclei, cellular infilteration and fibrosis. Ultrastructurally, hepatocytes showed disintegration of cellular organelles, destructed mitochondria and pyknotic nuclei. Coadministration of diclofenac with ginger extract showed a slight improvement in some hepatocytes that looked normal in both LM and EM examination but still others were markedly affected and showing signs of degeneration. Conclusion: Results obtained in this study demonstrated that high doses of diclofenac induced histological and ultrastructural changes in the liver due to oxidative stress and the use of ginger extract had partially improved the toxic effect of diclofenac.

Abstract: Berberis, a member of family Berberidaceae serves as ‘wildlife-clinic’ in nature. Berberis pseudumbellata subsp. gilgitica is endemic to the area and has become critically endangered. For the first time research documented unique epigenetic behaviour of different mountain wildlife and zoopharmacological practices of traditional communities from CKNP. When wildlife gets physical hurts, it rushes towards Berberis plants and eat berries, chew leaves or bark, which is found significant (p<0.001). Such behaviour is untaught, not learned, and automatic but seems pre-programmed instinctively triggered reflexed. This is observed in avifauna (House Sparrow, Chakor, Ram Chakor) and angulates (Flare horned Markhor, Himalayan Ibex) only. 79.03%, 36.51% hunters (SD±30.02), 83.24%, 58.23% shepherds (SD±17.68) and 41.92%, 17.11% local population (SD±17.54) believe and have personal observations respectively for Berberis-wildpharma interaction.  Traditionally it is used zoopharmacologically for bone healing of limbs (93.67%), other bone fracture and injury (90.91%), other internal injuries (85.53%), external injuries (73.33%), delivery of sheep (38.12%), goat (17.36%) and cow (19.87%). No such observation was recorded with respect to herpetofauna and carnivores.

Abstract: Lactic acid bacteria are used recently as probiotics and as protective cultures in fermented food products. This is due to their ability to produce proteinacous antimicrobial agents, lactic acid and diacetyle. The prime objective of this work was to select a probiotic bacterium which could be used as protective culture.  Characterization of bacteriocin by physicochemical techniques and inhibition of food-borne pathogens were carried out. Molecular methods were used for identification of bacterial strains used. Out of 100 lactic acid bacterial strains, the most inhibitory strain (Z55 strain) isolated from Arabian yoghurt (Zabady) inhibited other lactic and bacteria and some food-borne pathogens. This Z55 strain was identified as Lactobacillus delbreukii subspecies bulgaricus and designated Lb. bulgaricus Z55. The inhibitory activity of cell free supernatant (CFS) of Lb. bulgaricus Z55 was lost by proteolytic enzymes, heat resistant. Consequently it was characterized as a bacteriocin. This bacteriocin was shown to consists of protein but has no lipidic or glucidic moieties in its active molecule. Its activity was stable in the pH range 2.0 to 7.0. Maximum bacteriocin production was obtained in MRS broth adjusted initially at pH 6.5 and incubated for 18 h at 350C when the producer organism was in the late logarithmic and early stationary phase of growth. A bacteriocin producer strain (Lb. bulgaricus Z55) inhibited many food-borne pathogens. The antimicrobial agent was showed to be protein and characterized as a bacteriocin

Abstract: The bacteriocin plantericin UG1 produced by Lactobacillus (Lb.) plantarum UG1 was purified herein by three steps including ammonium sulphate precipitation, dissociation of bacteriocin activity and chromatographic separation. At pH 6.0 and 60% ammonium sulphate saturation, the precipitated pellets contained maximal plantaricin UG1 activity of about 22880 AU/ml. Some dissociating agents dissociated plantaricin UG1 activity, thereby releasing more active subunits. The bacteriocin plantaricin UG1 existed in ammonium sulphate pellets was dialysed against potassium phosphate buffer pH 6.5 and was easily purified using chromatographic separation. Purified plantaricin UG1 activity showed 54.69 fold -increase than that obtained in cell free supernatant (CFS). The purity of plantaricin UG1 was judged by SDS-PAGE which resolved a 3.7 KDa and 1.8 KDa protein bands; indicating that plantaricin UG1 is two polypeptides. Consequently it is another bacteriocin within class 11 b bacteriocins. Amino acid composition of plantaricin UG1 showed 29 to 31 amino acids. Amino acid sequence of plantaricin UG1 showed a double glycine leader and proved that it is a novel variant of plantaricins.

Abstract: This paper presents the results of the development of the optimal conditions for new TB-FLU Esat6 2A Ag85A recombinant strain cultivation in Vero cell culture. The studies revealed that the maximum accumulation of the virus in cell culture can be achieved with 0,001 TCD50/cell infecting dose, 34,0 ± 0,5 °C incubation temperature and 72 hours of incubation time. The highest reproductive activity of the virus was obtained using trypsin (Sigma # T4049, Lot10D169, # Lot020M7022T1426-1g) at a concentration 2 µg/ml. The TB-FLU Esat6 2A Ag85A recombinant strain expressing mycobacterial proteins Esat6 and Ag85A with open reading frame of NS1 protein of the influenza virus is genetically stable and capable to maintain enthetic inserts during 10 consecutive passages in Vero cell culture. Subject to the established cultivation parameters the recombinant virus accumulation level reached up to 7,75 ± 0,08 lg TCD50/cm3 with 7,0 log2hemagglutinating titer, which is quite suitable for the development of a TB vaccine for human health care.

Abstract: In this work, we derived a Fredholm-Volterra integral equation (F-VIE) of the second kind from the plane strain problem of the bounded layer medium composed of three different materials. These different materials contain a crack on one of the interface. In addition, the existence of a unique solution of F-VIE is considered in the space  QUOTE  . The integral equation is solved by using quadratic method to obtain SFIEs. Then, we used two direction, the first direction, is by removing the singularity and using Legendre polynomials. While the other, by using Toeplitz matrix method (TMM) and product Nystrom method (PNM). Finally, numerical examples are considered and the estimate error, in each case, is compared between the three methods.

Abstract: Background Complications such as gastrointestinal disorders may occur in patients after stroke, which affect their recovery. It is still obscure whether the stress from movement inabilities after stroke influences the intestinal barrier functions. We therefore assessed the intestinal mucosal changes in a post-stroke rat model under the restraint stress, which simulated movement restriction in post-stroke patients. Methods Male SD rats in stroke group (M) and post-stroke restraint group (MS) received permanent middle cerebral artery occlusion (MCAO) operation to establish a stroke rat model, rats in post-stroke restraint group (MS) were restrained in fixator 24 hours later after MCAO operation. The rats in sham-operated restraint group (JS) received restraint only after sham operation. Serum corticotrophin releasing factor(CRF), D-lactate (D-Lac), endotoxin (LPS) and diamine oxidase (DAO) level were evaluated by ELISA assay; Terminal ileum tissue tight junction proteins ZO-1, occludin, claudin-1, claudin-2, claudin-3 and claudin-4 level were analyzed by western blotting; Terminal ileum tissue CRF, CRF-r1, CRF-r2 and brain tissue TNF-α, CRP, CRF expression level were investigated by immunohistochemistry. Results As compared with sham group (J), peripheral blood serum D - Lac, DAO, LPS, CRF levels increased (all P<0.05), TNF-α, CRP, CRF expression levels in the central nervous system were also significantly increased (P<0.01), while the claudin, ZO-1, claudin-1, claudin-2 levels in the intestinal mucosa decreased significantly (all P<0.01) in post-stroke restraint group (MS), stroke group(M) and sham-operated restraint group (JS). Peripheral blood serum DAO, LPS, CRF levels in post-stroke restraint group (MS) were increased compared with stroke group (M) (all P0.05). The ZO-1, claudin-1, claudin-2 levels in intestinal mucosa were decreased compared with stroke group (M) (all P0.01), while claudin-3 claudin-4 levels were increased compared with stroke group (M) (all P0.01). Terminal ileum tissue CRF-r1 expression levels in post-stroke restraint group (MS) was increased compared with stroke group (M) (P<0.05), while CRF-r2 expression level was no significant difference in this two groups (P>0.05). Conclusion Restraint stress deteriorates the intestinal barrier functions in rats after stroke.

Abstract: Aspartame (ASP) is one of the most widely artificial sweeteners consumed in various countries which added to a large variety of foods specially low calorie beverages. Flaxseed oil (FXO) is marketed as a nutritional supplement. It contains linolenic acid poly unsaturated fatty acid (omega-3- PUFA), that have antioxidant, anti-inflammatory effects and many beneficial health effects. Coenzyme Q10 (Co Q10) has gained considerable attention as a dietary supplement capable of influencing cellular bioenergetics, antioxidants and as a supplementary treatment for some chronic diseases. The present study is an effort aimed to investigate the possible protective influence of FXO and Co Q10 on renal genomic instability induced by aspartame. Adult male rats were divided into 4 groups (n=6), animals of group 1 (control) had free access to water and food materials. Group 2 (ASP) was daily administered orally Ad libitum drinking water containing 0.25 g/L aspartame. Group 3 (ASP+ FXO) was daily administered diet contains 15% FXO in combination with aspartame. Group 4 (ASP+ CoQ10) was daily administered diet contains 500 mg CQ10/kg diet in combination with aspartame till the end of the experiment after 60 days. Our results revealed that, oral administration of aspartame significantly increased serum urea, BUN, Creatinine, potassium levels and decreased sodium level. Also Our results showed that renal GSH level, GSH-Px, GSH-R, G6PDH, SOD activities and DNA, RNA, zinc content were significantly decreased. While the levels of H2O2, NO, TNF- α and percentage of DNA fragmentation were significantly increased comparing with normal control group. Oral administration of FXO and CoQ 10 along with aspartame ameliorated serum and renal alterations.

Abstract: In modern and developed cities, large office buildings and factories occupy the center of city destroying the legibility of these areas. The city center of Kuala Lumpur (KLCC) was chosen as a case study because this area faces these challenges. In this study, the relationship between geometry and legibility was reviewed using two models that were created base on the literature. The two models were an existing vicinity of KLCC and a hypothetical model that analyzed by Space Syntax. The results were further analyzed using a T-test and the correlations were examined using SPSS. Enhanced integration as a result accessibility was observed. There was also a strong correlation between integration and connectivity in the hypothetical model. According to this simulation study, regular geometry can increase integration, accessibility, intelligibility and legibility in urban spaces.

Abstract: Congenital heart disease (CHD) mainly is caused by the incomplete development of the heart during the first 6 weeks of pregnancy. Chromosomal and genetic abnormalities in the child and high levels of homocysteine in the blood are some of the risk factors related to CHD. Several studies in various populations have been done to determine the candidate genes in the predisposition to CHD with contradictory results, but there have been no studies that had been found in Malaysian CHD patients on homocysteine gene polymorphisms. Hence, this study was conducted to determine the allelic and genotypic analysis of the polymorphisms in candidate genes of the homocysteine enzymes; Methylenetetrahydrofolate Reductase (MTHFR), Cystathionine-b-synthase (CBS), Methionine Synthase (MTR) and Methionine Synthase Reductase (MTRR) genes. Based on the inclusion and exclusion criteria, buccal or blood samples were collected from 150 Malaysian non-syndromic CHD patients and 150 samples from healthy subjects as controls with no matching of age, genders and race between cases and controls. Genomic DNA was extracted from the samples using commercially available kits and the genotyping analysis for C677T MTHFR, A1298C MTHFR, A66G MTRR, A2756G MTR and 844ins68 CBS gene polymorphisms were analyzed using PCR-RFLP analysis. There was a significant difference observed in MTHFR A1298C gene polymorphism between cases and controls (P=0.008). However, there was no significant difference was observed for MTHFR C677T, MTRR A66G, MTR A2756G and CBS 844ins68 gene polymorphism. The association of MTHFR A1298C with the development of CHD in this study emphasis the role of MTHFR gene in the pathogenesis of non-syndromic CHD in Malaysian subjects.

Abstract: We report in this work the antifungal and antioxydant activities of Juglans regia L. natural and treated barks on several vaginal Candida isolates and Candida type strains. Water, methanol, ethyl acetate and diluted acetone extracts of natural and colored J. regia barks were screened for in vitro activity against vaginal Candida strains. These plants were selected due to their traditional use for the treatment of fungal infections. Plant preparations were screened for antifungal activity using a standard agar disc diffusion assay. Following study of the antifungal activity of plant extracts, their minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) values were determined using broth microdilution assay. Several antioxydant properties of this plant were tested such as total phenolic content and determination of reducing power. Among the four J. regia L. extracts (for natural and colored bark), methanolic extract of natural bark had the best antifungal activity against all vaginal Candida strains. The most important MICs and MFCs values of the methanol extract were obtained for the majority of the vaginal Candida isolates (MIC = 0.012 mg/ ml and MFC = 0.024 mg/ml) as compared to amphotericin B (MIC = 0.097 mg / ml and MFC: 0.78 mg/ml). This study reveals that the antioxidant activity of “Swak” extract was more important for natural bark than the treated bark. This plant can contain compounds with therapeutic potential against vaginal Candida strains and, hence, their possible use as therapeutic agents.

Abstract: During life, everybody experience several ways of stress. Most authors agree that although anyone may experience stress, the highest incidence is found among caregivers or professionals responsible for the development of other people, such as physicians, nurses, teachers, social workers and psychologist. The nursing staff suffers the total, concentrated and immediate impact of stress deriving from patient’s care. Nurse job satisfaction is a multidimensional phenomenon that is influenced by many variables, stress has been identified as the strongest predictor of nurse job satisfaction, which in turn reflects positively or negatively on nurse retention. This study aimed to investigate the presence of work related stress and its impact on nurses’ job satisfaction. One hundred female nurses were recruited, 60 working in ICU of both adult and pediatrics at King Saud Medical Complex, and 40 working in labor room at Al-Yamamah maternity hospital. Tools for data collection include: Interview questionnaire, Nursing Stress Scale (NSS Gray –Toft & Anderson, 1981) which was 34 items scale used to measure any situations perceived by the participants as threatening because of mismatch between the situation demands and the individuals coping abilities. The Job Satisfaction Survey (JSS).JSS, was 36 items, nine facet scales to assess employee attitudes about the job and aspects of the job. Each facet is assessed with four items, and a total score is computed from all items. Results of this study revealed that near half of the subjects (49%) perceived frequently stress, while only 7% perceived extremely stress. Also results revealed that, 47% of the subjects were ambivalent in their response to job satisfaction and 35% were satisfied. A significant positive relation between level of perceived stress and level of job satisfaction were found in this study (p=0,009).This study recommended another informative study to include another departments in a multi dimensional settings of health care and also recommended that the organizations that employ nurses should implement programs to monitor and manage stress especially regarding staff issues and job demands.

Abstract: Different scenarios for the efficient transmission of images over wireless sensor networks are presented. The research is focused on the use of the IEEE 802.15.4 ZigBee for applying the proposed scenarios. The heart of these scenarios is a novel chaotic interleaving scheme, which can tolerate error bursts. The investigation studies the performance of the proposed interleaver with convolutional codes having different constraint lengths (K). A comparison study between the traditional block interleaving scheme and the proposed chaotic interleaving scheme for image transmission over a correlated fading channel is presented. The simulation results show the superiority of the proposed chaotic interleaving scheme. The results also prove that the chaotic interleaver on a packet-by-packet basis gives a high quality image with (K=3) and eliminates the need for a complex encoder having K=7.

Abstract: Toxoplasma gondii is an intracellular parasite of warm-blooded animals that causes one of the most common parasitic infections in humans. It is endemic worldwide and 15 to 85% of the human populations are asymptomatically infected. Here, the aim of this study is to determine the prevalence of toxoplama antibodies in pregnant women in Hail city, KSA. In 2013, 6076 pregnant women were examined for IgG and IgM antibodies using ELISA technique. The age range was 19-43 years. The overall IgG seroprevalence was 9.8% and IgM seoprevalnce was 0.6%. The IgM is indicative of low recent exposure to the parasite. In conclusion, the overall seroprevalance indicate a very low percentage in pregnant women living in Hail, KSA. This lowers the risk of contracting T. gondii infections which minimize the risk congenital toxoplasmosis.

Abstract: Parents play an important role in how their children use media. There has been limited research in Malaysia on the influence of four parental mediation strategies (active co-use, interaction restriction, technical restriction and monitoring) on children’s positive use of the Internet. This study investigates the relationship between the four mediation strategies and children’s positive use of the Internet. The data were collected from 384 children aged 9 to 16, and 384 parents; both types of data were collected using self-administered questionnaires. The study was conducted in the state of Selangor, Malaysia by using stratified sampling. Path analysis revealed that parental mediation via active co-use and interaction restriction had a significant negative relationship with children’s positive use of the Internet, while technical restriction had a significant positive relationship with children’s positive use of the Internet. Parental mediation via monitoring had non-significant relationship with children’s positive use of the Internet. Thus, parental mediation through technical restriction seems to be a better strategy in promoting children’s positive use of the Internet. The study emphasizes the role of parents when dealing with children’s positive use of the Internet. Parents should place greater attention on their technical restriction strategy, rather than using active co-use, interaction restriction or monitoring strategies. This will provide more online opportunities for children.

Abstract: Photocopy machines are a source of indoor air pollution. This study, conducted at Gulberg, Walton, D.H.A, Shadman, R.A.Bazar, Barket Market, Firdous Market, and Nabah road in Lahore aimed at assessing the occupational hazards to which photocopy machine operators are exposed. The study was conducted in hot and cold season for monitoring at 36 sites among 126 photocopy operators by socioeconomic survey. Very few operators (12%) used protective measures. 47% of the operators had visual discomfort from machine’s light while only 27% got disturbed from the noise of the machine. Noise level at majority of the photocopy shops were within the Standard limits (70dBA). PM10 concentration at majority of the shops exceeded the 250 µg/m3 ambient air quality standard. Statistical analysis of the Air pollutants (VOC, PM10, O3, CO, SOX) showed a high statistical significance as the p value was < 0.005. Dry mouth was most common health issue among the photocopy operators and was most frequent in age group 35 to 40 while fatigue and headache were the most common health outcomes affecting all age groups almost in the same frequency. Ergonomic issue comparison showed that neck pain and swelling of feet was most frequent in age group 35 – 40 and 41 – 46. Back pain was most common ergonomic problem affecting all the age groups. A strong positive correlation exists between PM10, Ozone, Carbon monoxide, SOx emitted from the photocopy machine. Emission levels of PM10, VOC, Ozone, CO, SOx were significantly high for Winter when compared with that of Summer season.

Abstract: The article discusses the usage of innovative technology in the educational system of Kazakhstan and the introduction in the educational process of teaching effective means. Modern educational system of Kazakhstan is characterized by the introduction of 12-year-old school model that guarantees the achievement of a specific result, implementing student-centered learning. School is seen as the main link in this focused training. Transition to 12 - year education will require updating the entire educational system that will ensure consistency with the legal and social norms, age, individual psychological and creative abilities. Thus, the main strategic direction of the school system in Kazakhstan is on the way to solve the problem of personality-oriented education. It reflects the humanistic trend in philosophy, psychology and pedagogy. The choice of this direction contributes to more efficient formation of an innovation culture among the students.

Abstract: The purpose of this study is to investigate the role of the induction program for novice teachers. This study focuses on the challenges faced by new teachers and how the induction program shaped the novice teachers at school compound. The research also looks at the support provided by school leaders’ and how effective the mentoring programs in helping the newly appointed teachers. This study employed naturalistic the case study approach which refers to their experiences as novice teachers with regards to challenges faced, supports and mentoring through in-depth qualitative interviews with six novice teachers that purposely selected from three different high performing schools. Novice teachers reflected that the schools actually have an informal induction program but the supports they received were rather lacking. The mentoring program look more like a buddy support system as the mentor program is not structured and utilized well. In addition, they also expressed some frustration over the lack of supports they received from school. It was recommended that the school leaders should formulate and implement a more structured plan for an induction program according to the needs of new teachers.

Abstract: Epidemiology of pathogenic variants of Rhizoctonia solani associated with potato crops in Egypt were analyzed. Twelve out of twenty isolates had comparable growth rates matching with that of the AG3 PT tester RS-114. Eleven isolates were multinucleate and anastomosed with each other and with RS114, confirming their membership of AG3. Rh21 was not AG3 but related to this group. The remaining 8 isolates did not anastomose with RS-114. Sequences of rDNA ITS of all isolates showed high similarities 98.8 and 98.7% with RS-114 and R. solani AG3 (JX050235), respectively; while Rh21 appeared to be distant 87.6% compared with RS-114 and 92.4% with AG2-1 R. solani (JQ676846). These results confirmed that all isolates except Rh21 belonged to AG3. A high frequency of SNPs was observed in 18S RNA and ITS1 rDNA. Genomic DNA of R. solani was also used for RAPD with 14 primers. The maximum number of bands was generated by primers OPX-13 and OPZ-11 (37 bands each) followed by OPV-17, OPS-19 and OPK-19. The 287 bands obtained with 14 primers were polymorphic showing high range of diversity with 100% polymorphism.

Abstract: Klebsiella pneumoniae (K. pneumonia), Staphylococcus aureus, Candida albicans and Candida tropicalis are opportunistic microbes associated with certain diseases such as diabetes, deep wounds and immunodeficiency. Those microbes have evolved their resistance to antibiotics in recent years. The aim of this study is to prepare oil extracts from the dried roots of Indian Costus and sea-Qust and test that oil's effectiveness on some bacteria and yeast. The results have recorded significantly high antimicrobial activity against K. pneumonia and C.tropicalis during treatment with Indian Costus oil, the sea-Qust oil was also very effective on C.albicans and S.aureus. Because the cell wall (SEM) of C. albicans was rough and wrinkled. Therefore, the budding of yeast became less with a treatment of Indian Costus oil. Thus, this result demonstrates that oil extract of Costus-type plants is effective that their oil extract could be considered as a natural alternative to antibiotics.

Abstract: Purpose: To evaluate the sensitivity and specificity of C - reactive protein (CRP) in diagnosis of acute appendicitis for suspected cases and possibility of adding it to Alvarado scoring system. Materials and Methods: This is a cross sectional prospective study of 124patientswho underwent appendectomy because of suspected acute appendicitis. Alvarado score was determined and considered significant when it is ≥7.CRP level was reported and considered abnormal when its level is above12 mg/dl. Combination of both was labelled as combined integrated test. If both were abnormal, the test was considered positive. Patients were categorized into 3 groups based on histopathological findings: normal appendix, acute appendicitis or complicated appendicitis. Results: Normal appendix was found in 24 patients (19.4%), acute appendicitis in 79(63.7%) and complicated appendicitis in 21 (16.9%). Alvarado score was ≥ 7 in 66 (83.5%) of acute appendicitis patients and in all 21(16.9%) of complicated appendicitis patients. CRP level was high in 98(79%) with mean of 62.3mg/dl in 66 (83.5%) of acute appendicitis patientsand 129.1mg/dl in 19(91%) of complicated appendicitis patients. Positive combined integrated test was found in 85(68.5%) and 78(92%) had appendicitis. Combined integrated test showed sensitivity of 78% and specificity of 71%. Conclusion: Combining CRP level with Alvarado score system showed sensitivity of 78% and specificity of 71%. Although that diagnosis of acute appendicitis usually based on clinical judgment, combined integrated test can be used to improve the accuracy of diagnosis and reduce the number of negative appendectomies. It is simple, cheap and can be obtained immediately to establish diagnosis.

Abstract: The transformed Paenibacillus polymyxa bacterial strain expressing Cry1C (tNMO10) that has dual function: bio-fertilizer and biocontrol agent of the Lepidopteron insects was used in spraying the cotton plants. plant leaves were checked for the presence of the transformed bacteria inside it by PCR detection of cry1C gene and total protein profiling. Two pairs of specific primers that give 2.2 kb and 3.7 kb amplified products from cry1C gene were used. Moreover, chlorophyll A, B & total chlorophyll A+B and carotenoid were determined. The data revealed, the presence of Cry1C toxin protein in the total cellular protein pattern of sprayed plant leaves with tNMO10 while was not found in those sprayed with parent strain (NMO10) and the reference strain Bt aizawai. The PCR could detect the 2.2 kb and 3.7 kb of the cry1C gene with plant leaves that sprayed with the tNMO10. Chlorophyll A, B and A+B showed increase in concentration in the second and fourth week after planting in the plant leaves treated with tNMO10 over the concentration of that leaves treated with the NMO10. The plant leaves that not treated with bacteria (control) showed the lowest concentration. The values of CA, CB and CA+B in the second week in plant leaves that treated with control, untransformed strain NMO10 and transformed strain tNMO10 respectively were as follow: CA: 18.63< 24.24< 28.59 mg/L, CB: 14.49< 21.73< 23.88 mg/L, CAB: 33.45< 41.65< 47.36 mg/L. In addition, the carotenoid content showed the same behavior of chlorophyll giving the following values in the second week with control, untransformed strain and transformed strain respectively, 4.18< 5.19< 5.69. Thus, the transformed bacteria tNMO10 caused improvement in the cotton plants through the increase of chlorophyll and carotenoid contents due to its presence survival and expressing its toxin Cry1C protein inside the cotton leaves.

Abstract: Scrum is a structured framework to support complex product development. However, Scrum methodology faces a challenge of managing large teams. To address this challenge, in this paper we propose a solution called Scrum of Scrums. In Scrum of Scrums, we divide the Scrum team into teams of the right size, and then organize them hierarchically into a Scrum of Scrums. The main goals of the proposed solution are to optimize communication between teams in Scrum of Scrums; to make the system work after integration of all parts; to reduce the dependencies between the parts of system; and to prevent the duplication of parts in the system.

Abstract: Saliva is produced by the submandibular (SMG), sublingual (SLG) and parotid (PTG) glands in addition to multiple minor salivary glands present throughout the mouth. Saliva and salivary glands are important because of their role in oral mucosal health. Food contaminants entering the body through the oral route are directly exposed to the action of saliva. The aim of the current study was to evaluate the histopathological and histochemical changes in SMG, SLG, and PTG glands in rats fed aflatoxin (AFB1) contaminated peanuts and evaluation of the decontamination effect with Ozone (O3). Thirty male Sprague-Dawley rats were divided into control and four tested Groups treated for 4 weeks as follow: Control Group fed regular basal diet, Group 1 fed control peanuts; Group 2 fed peanuts treated with O3 (40 mg) for 10 min; Group 3 fed AFB1 contaminated peanuts (1.5 mg/ kg) and Group (4) fed AFB1 contaminated peanuts treated with O3 using the same dose and period as in Group 2. Tissue specimens of SLG, SMG and PTG were taken at the end of experiment and fixed for histological and histochemical examinations. The results indicated that AFB1 increased the incidence of histopathological alterations in SMG, SLG and PTG. These alterations were manifested by pleomorphic serous acinar and vacuolar changes as well as fatty degeneration of acinar cells. The results also revealed a marked dilatation in the stromal spaces which resulted in a significant increase in fibrous tissues mainly collagen fibers especially in SMG and PTG. Some acinar nuclei were replaced by irregular, hypertrophy chromatin condensed mass and lost their nuclear envelop. The histochemical results showed that AFB1 also induced a significant decrease in total protein and acid glycoprotein. All these alterations were improved significantly in the group fed with the Ozone treated AFB1 contaminated diet. It could be concluded that AFB1 induced severe toxic effects on the studied salivary glands and these alterations could be prevented or reduced when AFB1 contaminated food was treated with Ozone. Moreover, Ozone itself was safe and did not show any detrimental effects.

Abstract: Coccidiosis in poultry is caused by protozoan parasites of the genus Eimeria, which is responsible for worldwide economic losses. Animals were divided into two groups of 10 mice per group. The first group was considered as the control group which gaveged distilled water twice a week. Toltrazuril 2.5% solution was given orally twice at a 1-week interval at a dose rate of 20 mg/kg body weight. Toltrazuril induced a significant increase in the level of intestinal and blood serum malondealdehyde. Also, toltrazuril induced a significant increase in the level of nitric oxide in the liver and blood of mice after one week post-treatment. Moreover, mice treated with toltrazuril for one week showed a significant increase in the blood level of glutathione. The current work investigated the antioxidant properties of toltrazuril in the mice liver, intestine and blood serum.

Abstract: The article is devoted to the problem of formation of positive ethnic identity of indigenous peoples of the Arctic Siberia. In this article are discusses the results of applied research in 2010-2014. Were used focus groups, questionnaires, personal interviews, expert opinion. In the study were directly involved Evenks, compactly living in Krasnoyarsk and in Evenkia. Were identified difficulties in interethnic communication between ethnic groups of indigenous peoples of the Arctic Siberia and the Russian ethnic group. The main reason of difficulties between the Evenks and Russians is that a large number of residents of the city of Krasnoyarsk and the Krasnoyarsk region have no information about the unique culture of the indigenous peoples of the Arctic Siberia. Evenks are afraid that endangered is their own unique culture. Are proposed measures to strengthen state support to preserve the unique culture of the Evenks.

Abstract: The plant tissue culture refers to the cultivation of different part of the plant, I both single cell organ tissue and under sterile circumstances at the media and industrial expansion in several controlled circumstances. The method of the plant tissue culture plays a pivotal role in the second green revolution that gene modification and biotechnology can be used for improving the crop harvest and also superiority. Through using plant tissue culture methods plants can be attained from several explants over direct or indirect morphogenesis and by somatic embryogenesis. Direct morphogenesis refers to the manufacture of shoots from explants deprived of passing over callus (unorganised tissue) stage while indirect morphogenesis relates to the generation of shoots over the callus stage. The culture in which an organized form of growing may be incessantly got is mentioned to as an organ culture. The most significant types of organ cultures used for micropropagation are meristem cultures, shoot cultures, embryo cultures and isolated root cultures. Callus cultures, suspension or cell cultures, protoplast cultures or other cultures are clustered as unorganised tissue cultures. The method that was used was the plant tissue culture in the circulation of several plants, that is also the most significant way for strawberry production, to get the plants disease-free viral and harvest plants like the mother plant or the manufacture of new kinds with good potentials that help the turnout for the cultivation of this plant, that is considered by its high fruits nutritional value. Most plants are affected by the micropropagation strawberry essential basics of the media, like hormones, vitamins, amino acids and physical state and the power source to the media. This paper is a summary of the classic and new technology plant tissue culture and the effect of some features, like the media and development managers (hormone plant), vitamins, amino acids and the physical case of the media. It frequently affects most of these features in the circulation of plants using the tissue culture over the effect in the creation of callus or embryos or vegetative emergence and development of roots, as well as in the fraction development of branches and roots as well as the development highlighted in the influence of these influences on the micropropagation of plants.

Abstract. Mainstreams of microwave technologies’ development and applications both in Russia and abroad are presented. Such directions as energetic efficiency of microwave technologies, ceramics and polymer heat treatment, basalt melting, drying of thermo-insulating materials, treatment of wastage are examined. Experimental studies were carried out on the electromagnetic field frequency oscillations of 2450 MHz. Polymer composite materials' thermal conductivity is very small and their heat treatment with gas or other known methods does not lead to the entire volume uniformity of heating, which leads to various flaws in the finished products during production. Future trends of different microwave technologies are shown especially in the part of even temperature field creation in materials as a pacing factor of quality goods production.

Abstract. The paper explores the evolutionary approach to the study of innovation processes at all levels of the economy. One of the new trends of the evolutionary approach is the global evolutionism, which examines the process of evolution as an inclusive process - from the creation of the universe to the present state of nature and society. The theory of global evolutionism is expressed in the general trend of dynamic processes towards progressive change and is inextricably linked with the theory of evolution based on the adaptation mechanisms. The difference between these theories is connected with the fact that the global evolutionism admits regression as a form of variability. Possibility of evolutionary progress or regress in innovation depends on the effectiveness of public policy.

Abstract. The article deals with the theoretical and philosophical foundations of Bolsheviks’ attitude towards religion in general and "sectarianism", in particular, during fledging years after the October Revolution. The relationship between philosophical views and practical policy of the Bolshevik government is analyzed. Unformedness of religious policy of the Soviet state in combination with the pre-revolutionary affection of the top Bolshevik leadership to "sectarians", who, like the Bolsheviks, were persecuted by the tsarist autocracy, as well as the hope for their support of young power, predetermined inconsistent, but the loyal in general attitude of the new state towards "sectarians" during fledging years after the October Revolution. Research attention is focused on the analysis and assessment of the Bolsheviks’ religious policy represented in the foreign English-language historiography.

Abstract. This paper presents the results of studying the effect of planting density of a promising variety  Yagodnyi 19 and the standard variety Nevsky on the yield and quality parameters of potato in the conditions of west Kazakhstan. Experimental factors included potato varieties (Nevsky and Yagodnyi 19) and different density planting (40,8, 47.6,  57.1 and 71.4 thou. pcs / ha). Studies showed that the optimum planting density is 57.1 thou. pcs / ha, at which the variety Nevsky formed a yield of - 25.43 thou / ha, Yagodnyi 19- 27.88 thou / ha. When the density was 57.1 thou pcs / ha, compared with the density 71.4 thou. pcs / ha seeds costs decrease by 25%. The average tuber weight decreases with the thickening of planting. With the increase of the planting norm, we can notice some decline in the marketability and an increase in the yield of seed tubers. Thus, there is a tendency of increasing starch and vitamin C content, and reducing the amount of nitrates in the tubers of the examined varieties.

Abstract. Usually at seal designing the complex of problems is observed, which is restricted only by the friction pair. These problems are leakage, reliability, deformations of seal rings, heat generation in a gap etc. This method is the main, but for research of some problems it is not sufficient. Development of program complexes on the basis of numerical methods does possible an application of the second additional method. The second method consists in the research of seal as parts of system of the engine or its unit. In article the possibilities of seal research as element of air secondary system, oil system and engine supports are observed. In each case leakage and a seal design are defined through demanded parameters of systems. The combination of two research methods does possible improvement not only separate seal unit, but also to perfect the systems and efficiency of entire engine.

Abstract. The article deals with the problems of ensuring of power generation security of European countries within the framework of bilateral cooperation between Russia and EU. The author outlines the main tendencies of world power generation evolution and analyzes the consumption of power generation resources in Europe. A typical feature in Europe is a strong power generation dependency on the Russian import. The currently implemented set of measures by EU implies the ‘third package’ which intensifies tension between Russia and EU. A compromise is needed with EU about the norms of application of the third package to Russian projects. To consolidate the power generation security on the European continent, the political dialog should be encouraged in order to stimulate cooperation in power generation supply.

Abstract: The study has shown that self-sufficiency of red meat can be achieved through adopting four different scenarios. The most important economic effects resulted from these four proposed scenarios are represented in that the increase in the amount of net meat will contribute in reducing the size of food gap of meat by about 41%, 0.6%, 24%, 18% and it will contribute in reducing the amount and the value of meat by about 56%, 8%, 33%, 25% in the first, second, third and fourth scenarios, respectively. Therefore, the study recommends that the state shall adopt the four proposed scenarios, especially the first and the third. The first scenario contributes to increase meat production through increasing the weights of all cattle and buffalo. However, the third scenario contributes to an increase in meat production through increasing the buffalo production of Egypt, compared to the increase in meat production through increasing the buffalo production of Egypt in the second and fourth scenarios.

Abstract: In this paper, phonetic editor system for learning English speaking will be introduced. Methods and the architecture of systems used to edit new lessons into proposed dictionary will be discussed taken into consideration pronunciation effects. Speak Correct system will be presented, which uses state of the art automatic speech recognition (ASR) and examines pronunciation errors by speech engine. Two levels of teaching will be implemented; consonants and vowels, which are important for speech recognition. The two levels cover detailed accent defects that describe such articulation. The core engine of the Speak Correct was trained using prerecorded 100 hours of speech and used these data to create a pronunciation-training database. The proposed editor framework is optimized to suit an embedded phonetic pronunciation database and is useful for analyzing and detecting speech errors in Arabian region.  The objectives of this paper is designing, implementing, and testing a prototype system that can add, and edit additional phonetic topics to cover pronunciation errors in teaching-based activities for adult students. In addition, the system will help teachers impart basic reading skills to assist students in comprehensive development.

Abstract: Hepatocyte transplantation (HCTX) is a strategy that has potential as a supportive treatment regimen and in some cases, an alternative to orthotopic liver transplantation (OLT) for a variety of liver disorders.Carbon tetrachloride (CCl4) intoxification in rodents is a commonly used model of both acute and chronic liver injury; it causes hepatocyte injury that is characterized by centrilobular necrosis and steatosis. This study demonstrates the therapeutic effect of fresh and microencapsulated hepatocytes in reduction of hepatotoxicity induced by CCl4 in hamsters administered a dose of 0.02 ml of 10% of CCl4 dissolved in corn oil /100 gm. body weight, for 24 hrs. Four groups each has ten hamsters (GI)- normal control uninjected, (GII)-negative control injected with CCl4 toxic dose intraperitoneally (i.p) for 24 hrs., (GIII)-injected with CCl4 toxic dose (i.p) for 24 hours, treated with cyclosporin as immuno-suppressive drug 24 hrs. post injection, then transplanted with fresh hepatocytes intrasplenically and (G IV)-injected with CCl4 toxic dose (i.p) for 24 hours, then transplanted with modified hepatocytes encapsulated in sodium alginate intrasplenically. Freshly isolated hepatocytes with a mean viability 92.97±1.2% were used for microencapsulation and transplantation. The mortality rate after hepatocytes transplantation in hamster groups (III and IV) was 50% but in negative control group was 90%. The biochemical parameters shows correction in liver function after transplantation of either fresh or microencapsulated hepatocytes comparing to negative control groups beside correction in oxidative stress and lipid peroxidation. Histological study showed the presence of transplanted hepatocytes in spleen of recipient. The conclusion of the above study showed that the animal groups that transplanted with microencapsulated hepatocytes survived without any immune rejection for the same period in comparison with fresh hepatocyte transplantation treated with immunosuppressive drug (cyclosporin), beside semi similar liver function recovery.

Abstract: The rice variety, MR232 with three nitrogen doses (80, 120 and 160 kg ha-1) showed that total dry matter production and leaf area index increased with increasing nitrogen doses at all growth stages. Though nitrogen @160 kg ha-1 produced the highest straw yield but its yield performance was lower due to unfavorable dry matter partitioning to economic yield. Nitrogen @ 120 kg ha-1 produced the highest grain yield (6.93 t ha-1) due to good harvest index.

Abstract: There is a stressing need in the literature for the application of the well-known social cognitive theory in the area of electronic commerce (e-commerce), but more specifically, in the developing countries such as Jordan. To better understand how individual differences influence the use of e-commerce (B2C e-commerce) a conceptual framework was developed and modeled based on Bandura’s social cognitive theory to test the importance of dynamic and stable traits (i.e., e-commerce self-efficacy, outcome expectations, trait anxiety, e-commerce anxiety, and consumer trust) on the intention of an individual to shop online. A self-administered questionnaire was used to capture the data from individual users in Jordan, from whom only 3% are e-commerce users (Arab Advisors Group Survey, 2011). In order to test the hypotheses introduced in the research model of this study, a method that engages individuals in a free simulation of real-life e-commerce situations was adopted. The findings indicate that e-commerce self-efficacy, outcome expectation, technology anxiety, and consumer trust are all significant predictors of the Jordanian intention to use e-commerce. E-commerce self-efficacy was the second powerful factor after consumer trust in determining consumer intention to shop online. In addition, this study surprisingly shows that general self-efficacy and trait anxiety do not influence the specific e-commerce self-efficacy. From a theoretical perspective, the study attempts to further our understanding of the nomological network of individual differences that lead to e-commerce usage. From a practical perspective, the findings can help in designing more effective strategies aiming to increase the use of e-commerce for individuals with different dispositional characteristics by providing some valuable insights into the performance and adoption of e-commerce by individual customers. These insights can help designers/developers, implementers, and managers of organizations of e-commerce systems to improve the effectiveness of their electronic services and increase the usage rates of e-commerce in the developing world in general.

Abstract: Effluents from municipal and industrial wastewater treatment plants, agricultural run-off and domestic drainage add numerous pollutants to the aquatic system. Among them is 17β-estradiol (E2), which is known as one of the strongest estrogenic chemical in the environment and commonly found in wastewater. This study was conducted to assess present concentration of E2 in aquatic environment of Peninsular Malaysia. Water samples were collected from rivers, estuaries and lakes at the northern, central and southern regions of Peninsular Malaysia. E2 concentration was determined using ELISA technique. Results revealed that the center region has the highest E2 average concentration (149.19 ng/L), followed by the northern region (95.04 ng/L) and southern region (15.66 ng/L). These results exhibit size of human population and activities may directly related with E2 elevation in aquatic environment as reflected by high human population in the central region. The lakes have the lowest concentration (11.83 ng/L), thus suggesting E2 discharges flow directly into river system. Comparison with other countries demonstrates E2 in aquatic environment in Peninsular Malaysia is higher several folds. If no immediate actions are implemented to control E2 level in the environment, there could be some adverse effects, especially to male aquatic animals, such as ova-testis, feminization, fertility reduction and villetogenin gene expression. Application of suitable bio-indicator is recommended in order to monitor estrogenic activities in aquatic environment.

Abstract: Objectives: To investigate the effect of Gonadotrophin releasing hormone (GnRH) antagonist treatment on the proliferative activity and morphology of the primate ovarian surface epithelium (OSE); the main origin of ovarian cancer.  Methods: This study was conducted at the Biological Sciences Institute at The University of Edinburgh, Edinburgh, United Kingdom from 2009-2010. Evaluation of OSE cell proliferation was assessed using 5-bromo-2-deoxyuridine (BrdU) labeling in paraffin- embedded tissue sections of marmoset ovaries obtained from previously treated marmoset monkey (n=44) with Antarelix (GnRH antagonist). Treatment administration was at zero time and on 5th day of ovulation. The extent of proliferation was also determined using same marker in cycling and pregnant animals in the OSE layer in proximity to stroma, antrum and corpus luteum (CL). The staining was performed at early, mid and late follicular and luteal phases and at early pregnancy. Results: GnRH antagonist administration at any time during follicular phase suppresses OSE cells proliferation. The epithelia overlaying the large antral follicles at pre-ovulatory stage and CL at early luteal phase displayed the maximum staining, while hardly few cells atop the stroma reacted with the marker. The morphology of the epithelial cells in contact with stroma was typical resting cuboidal shaped with tight attachment to basement layer. The cells above CL were prominently squamous type with loosened attachment, and those over large antral follicle were flattened and disorganized. Apparently, the cell multiplication and intercellular adhesion was distorted in the layers above CL and antrum, which correlates with their proliferative activity. Conclusion: This study concludes that GnRH antagonist treatment can alleviate the OSE proliferation, therefore can reduce the risk of ovarian cancer development.

Abstract: Ammonia (NH3), a kind of compound present in the air or natural water, has the simplest chemical structure among all nitrogen compounds. At a pH below 8, ammonia will interact with water molecule and exist in the form of ammonium ionsNH4+ after dissolved in water. This paper utilizes extended-gate indium tin oxide/ polyethylene terephthalate (ITO/PET) ion selective field effect transistors to make durable ammonium ion selective electrode, and investigates influences of each parameter on overall reaction. Results of several experiments show detectable concentration of ammonium ion is 10-5 ~ 1M, with a linear range of about 0.99 and an average sensitivity of 55.09 mV / pNH4+. Buffer solution is measured by virtue of PB and Tris. Use of Tris buffer can make measurement results tend to be stable. Experimental range of urea concentration spread is 1mg/dl~8mg/dl. Such spread result indicates electrode reaction under low urea concentration is more sensitive than common sensor and limit of detection is lower. In terms of human urea nitrogen detection, this method can be used for diluting normal human urea or blood to an optimal detectable concentration and thus obtaining the most sensitive and reliable reaction result.

Abstract: Microorganisms are good sources for the production of biologically active substances. The main purpose of this work is to study the antimicrobial and the chitinase activity of a bacterial isolate collected from Medicago sativa rhizosphere field of Helwan region, Cairo, Egypt. According to Bergy’s manual of systematic bacteriology, the isolate was identified as Bacillus circulans. The antimicrobial activitiy of Bacillus circulans was studied against bacteria and fungi. Our results indicate the antimicrobial activity of Bacillus circulans against gram-positive, gram-negative bacteria and plant pathogenic fungi. The maximal antimicrobial activity was observed after 24 h at 30oC and pH 8. The best carbon and nitrogen sources was starch and DL-methionin respectively. The GC-mass analysis showed that the compound responsible for antimicrobial activity is 4-(Diphenylmethyl)-6 ethoxycarbonyl-1-phenyl-1H-pyranolo [4, 3-c] pyridine with molecular formula C28 H23 N3 O2. The Minimum Inhibitory Concentration (MIC) of C28H23N3O2 against Gram positive, Gram negative bacteria and unicellular fungi was in range of 0.5-2µg/ml. interstengly, Bacillus circulans showed chitinase activity against different pathogenic plant fungi. Due to the antimicrobial and chitinase activity of Bacillus circulans, it could be used in industry for production of antibacterial compound and in biological control against different plant pathogen.

Abstract: Purpose: The difference between diagnosed patients with vesicoureteral reflux (VUR) after urinary tract infection (UTI) and diagnosed VUR patients following non-UTI causes in terms of severity, laterality, scar formation, breakthrough infection and necessity for surgery was evaluated. Methods and Materials: In this analytic cross-sectional study 120 neonates and children with VUR were followed-up in two separate groups: diagnosed VUR after UTI (78 patients) and diagnosed VUR after non-UTI causes (42 patients). All patients were taken prophylactic antibiotic. Variables were included: gender, severity of VUR, laterality, renal scar at the time of diagnosis and during follow-up, incidence of break-through infection and necessity for surgery .Information during follow-up were entered in data forms and the results remained statistically analyzed. Results: Average follow-up time in VUR group after UTI were 46.2±3.4 months compared with VUR group following non-UTI causes, 48±5.2 months. Considering severity of reflux, Uni or bilateral VUR, diagnosis of renal scarring and new scar formation, frequency of break-through infection and necessity for surgery, there was no expressive statistical difference between two VUR group after UTI and non-UTI causes. Conclusion: The consequence of this study reveals that patients whom diagnosis of VUR were not after UTI should be followed-up entirely like VUR group after UTI and the UTIs in this group must be diagnosed promptly and well be treated to prevent development of scar formation.

Abstract: The protective effect of B vitamins combination against zinc oxid bulk (ZnO-bulk) and its nanparticles (ZnO-NPs) toxicity -induced kidney damage in rats was investigated. ZnO- bulk or its NPs were administered orally (500 mg /kg body weight) for 10 consecutive days. The results revealed that oral co-ingestion of of B vitamins combination (250 mg B3, 60 mg B6 and 0.6 mg B12 / Kg body weight) daily for 3 weeks to rats intoxicated by either ZnO- bulk or its NPs markedly ameliorated increases in serum markers of kidney function, including uric acid and creatinine. Also the used vitamins in combination down-modulated ZnO caused dramatic increases in serum pro-inflammatory biomarkers including, tumor necrosis factor- α (TNF-α), and C-reactive protein (CRP) as well as in serum vascular endothelial growth factor (VEGF) (angiogenic factor) in intoxicated rats compared with intoxicated untreated ones. In addition, the result showed that B vitamins effectively ameliorated the increased malondialdehyde (MDA, a major product of lipid peroxidation), the decrease in antioxidant enzyme, glutathione peroxidase (GPx), oxidative deoxyribonucleic acid (DNA) damage and the increase in the apoptosis marker caspase 3 in kidneys of intoxicated rats with either ZnO- bulk or its NPs compared with intoxicated untreated.In conclusion, prophylactic treatment with the current used B vitamins in combination may be beneficial in protecting kidney tissue from the toxic impact of ZnO- bulk or its NPs.

Abstract: The present study was undertaken to investigate the PrP gene polymorphism at codon 154 in two major Tunisian sheep breeds, namely the Barbarine (B) and Western thin tail (W). It involved 24 animals, with 12 from each breed. Genomic DNA was extracted from whole blood samples and amplified by PCR using primers flanking the codon 154 of the PrP gene. The amplicons were sequenced to determine the genotype of each animal. Amplification was performed for all animals, generating an amplicon size of 180 bp. The findings revealed the prevalence of a homozygote genotype RR in the population. The heterozygote genotype RH was observed in only one animal belonging to the W breed. The homozygote genotype HH was not observed in both breeds.

Abstract: Transmissible spongiform encephalopathies (TSE) are a complex group of fatal neurodegenerative diseases affecting humans and animals, of which scrapie is a prototype in sheep and goats. Although sheep scrapie has been known for a long time, considerable uncertainties still surround its occurrence, including its pathophysiological features, modes of action, and mechanisms of spread. With these concerns in mind, the present study was undertaken to sequence and analyze PrP gene polymorphism at codon 171 in two Tunisian sheep breeds (Barbarine and Western thin tail). The H allele was detected at a significantly lower frequency when compared to the Q and R alleles in both breeds. The findings also revealed three genotypes (QQ, RQ and HQ) in the overall population, with frequencies of 0.5%, 33.33%, and 16.67%, respectively.

Abstract: Scrapie is a fatal transmissible spongiform encephalopathy (TSE). Several studies have shown that in sheep, susceptibility to scrapie is mainly influenced by the polymorphism of the PrP gene. The identification of PrP genotypes for scrapie is very important for every country in order to develop and implement scrapie breeding program. In Tunisia, no study has focused on the characterization of Tunisian sheep population on genetic resistance to scrapie. The aim of this study was to assess the PrP polymorphisms in a total of 48 healthy sheep from two Tunisian native sheep breeds. There were three alleles and three genotypes observed based on codons 136, 154 and 171 of PrP gene. The ARQ allele was predominant (72.92%) while the ARH allele was found at low frequency in the global population (8.33%).

Abstract: Analysis of mitotic process and description of chromosome aberrations are important aspects in plant genetics to assess the effect of medicinal plant extract. Ethnopharmacological relevance: P. granatum extracts have been reported to exert multiple health effects, e.g. anti-inflammatory, antibacterial, and antidiarrheal, etc. However, the antiproliferative effects were not as extensively studied, including those of protocatachuic acid, a major constituent of the extract. This work aims at analyzing the constituents of the acetone extract of the plant and testing its antiproliferative effects. Material and Methods: Fingerprint of Punica granatum L. polyphenol acetone extract was analyzed using HPLC, UV-detection. Allium cepa L. root meristem was used as bioassay system. The study groups included 3 concentrations of the extract (0.1, 0.5, 0.75/ 100 mL) with 3 exposure times for each (3, 6 and 12 hours) and control for each treatment. For every experiment, 5 samples with 1,000 cells were studied. Effects on cytological and ultrastructure assays were done. As well as biochemical and molecular analyses (estimation of total protein content, DNA ladder, detection of nuclease activity) were done. Results: HPLC authentication of the extract revealed the presence of 15 fractions, of which protocatechuic acid, O-H Benzoic, chlorogenic acid, phenol and quarecetin were quantified. The application of acetone extract resulted in changes in ultrastructure of all organelles, reverse the viability of meristem cells and induce programmed cell death. The inhibitory effect of acetone extract was found to be dose and exposure time dependent. The mitotic process was associated with metaphase arrest and the disappearance of telophase stage that abolish the continuity of mitotic activity. There was a significant increase in nuclease activity enzymes, which in turn enhanced the cleavage of DNA to induce a typical ladder form. Conclusion: The total polyphenol extract of Punica granatum L. reprogram Allium cepa L. meristematic cells resulting in programmed cell death.

Abstract: The migration of skilled workers moving from their native countries to host in pursuit of economic opportunities has a negative effect on the native countries in terms of cost of leaving, shortage of skilled human resource and overall economic development of those countries. Such movement of skilled human resource is called Brain drain. In the prevailing Global scenario of competition, it would not be a wise move to solely focus on reversing and discouraging the Brain Drain. As human resource can be more productive and developed by exposing to continuous training and learning which can only possible if we let a specific portion of our brain to developed countries for the sake of more skills and knowledge. However, government should fulfill its utmost priority to attract and engage that Brain by providing congenial atmosphere to help and support that Brain to contribute its share in the National Economy.

Abstract: The effects of addition of different monomers on the intrinsic viscosity of poly(vinyl chloride) PVC have been studied. Three different additive monomers from N-phenyl maleimide derivatives were added with the same concentration 0.015 gm/1gm PVC as stabilizers. These stabilizers are N-phenyl maleimide NPMI, Para-carboxy N-phenyl maleimide PC-NPMI and Para-amide carboxy N-phenyl maleimide PA-NPMI. Their stabilizing efficiencies were evaluated by measuring the intrinsic viscosity of the solution samples. It was found that the PC-NPMI monomer is proved not to be sufficient effective in increasing the average molecular mass. So, the effect of its addition with different concentrations was studied. The results indicate that the sample with 0.01 gm PC-NPMI /1gm PVC has higher intrinsic viscosity. Thus this sample was chosen to be a subject for further study to investigate the effect of electron beam irradiation on its molecular and color properties. Samples from the 0.01 gm PC-NPMI /1gm PVC were irradiated with electron beam doses in the range 50-300 kGy. It is found that the irradiation in the dose range 50-250 kGy enhances the intrinsic viscosity and the color response of the samples.

Abstract: Research Purpose: By conducting fMRI research on insomniacs with depression in resting state, this experiment reveals the abnormality in the patient’s DMN and its neural pathogenesis, and different degrees of depression's impact on the neural networks causing weakened cognitive function. Consequently, it offers objective imageological basis for clinical cognitive impairment treatment and evaluation of such treatment. Method: a group of 40 cases are selected as the insomniac group, consisting of 20 as mild depression group and 20 as moderate depression group. And another 40 cases are selected as the HC group. All the testees take PSQI, HAMD, 3.0T routine MRI examination and fMRI, and cases with abnormal brain structures are excluded. Then on the basis of PCC as the seed point, comparisons are made between the insomniac group and HC group, between mild and moderate depression group in terms of their DMN differences. Result: Depressive Insomniac Group have stronger functional connection with PCC/pC: bilateral superior frontal gyri and bilateral middle cingulate gyri; the following regions have weaker functional connection: left occipital lobe lingual gyrus/ parahippocampal gyrus/ fusiform gyrus, right superior temporal gyrus/temporal pole, right middle temporal gyrus/middle occipital gyrus, and left occipital lobe/middle temporal gyrus. Compared with Mildly Depressive Group, the following encephalic regions of Moderately Depressive Insomniac Group have stronger functional connection with PCC/pC: right middle cingulate cortex and right frontal gyrus; the following regions have weaker functional connection: left parahippocampal gyrus. Conclusion: There is abnormity in the brain default mode network of insomniacs with depressive symptoms. The depression degree of insomniacs varies. There are differences in the brain default mode network. It is suggested that there is a positive correlation between the middle cingulate gyrus and insomnia and depression, this is also shown between the activated degree of the middle frontal gyrus and insomnia and depression. There is a negative correlation between the activated degree of the parahippocampal gyrus and insomnia and depression. This research also suggested that there is a cognitive disorder and a neutral network mechanism of emotion regulation disorder among depressive insomniacs.

Abstract: Object: This study intends to explore the changes of WHO-UCLA word study and the Digital Pin Test, as well as the functional connectivity on hippocampus with the whole brain, in order to find cognitive damage mechanism in primary insomnia (PI). Method: 40 primary insomniacs are chosen according to the Diagnostic and Statistical Manual of Mental Disorders (4th edition, DSM-IV) and International Classification of Sleep Disorders (ICSD) criteria as well as 50 healthy subjects. The WHO-UCLA word learning and the Digital Pin Test are applied to evaluate the subjects’ word study ability and vigilance. The above-mentioned subjects take a fMRI on the whole brain in a resting state, with left and right hippocampus as the seed points to establish functional connection with other encephalic regions, followed by a comparison of the test results of the two groups. Results: Pittsburgh Sleep Quality Index (PSQI) (t=18.181,p<0.01) and HAMA (t=29.242,p<0.01) of PI patients were significantly higher than those of the healthy control group, but the PI group’s Digital Pin Test efficiency and WHO-UCLA word learning were significantly lower than those of the HC group. There exists a positive correlation between the PI group’s subjective insomnia degree and their anxiety and the course of a disease. The PI group’s WHO-UCLA word study ability has a negative correlation between the total PSQI score and the Digital Pin Test efficiency, and a positive correlation occurs in relation with an educational background. The right hippocampus of PI patients showed strengthened functional connection with the left limbic lobe, the right thalamus and the left brainstem. The left hippocampus of PI patients displayed enhanced functional connection with the bilateral thalamus. Conclusion: The ability of the PI patients on the WHO-UCLA word study and the Digital Pin Test efficiency decline, which keeps a negative correlation with depression, in relation with the course of the disease, sleep quality, and a positive correlation occurs with an educational background. The patients’ hippocampus has a stronger functional connection with the bilateral thalamus, left limbic lobe, left brainstem, which is the mechanism leading to the cognitive damage of PI patients.

Abstract: Clavicular fractures account for 2% to 2.6% of all fractures, while fractures of the midshaft account for 69% to 82% percent of all clavicular fractures. However, the optimal treatment for midshaft clavicle fracture remains a topic of debate. A meta-analysis of randomized controlled trials was conducted to evaluate the functional outcome and satisfaction of operative treatment and conservative treatment in midshaft calvicle fractures. A systematic electronic literature search was performed using 4 electronic databases (MEDLINE, EMBASE, Biosis Previews and PubMed). After evaluation of the methodological quality of included publications, five RCTs were identified comparing operative treatment and conservative treatment for midshaft clavicular fracture. Five studies with 401 clavicular fractures were included. Operative treatment significantly reduced nonunion rates, malunion rates, union-time, as well as neurologic symptoms. More satisfaction with ultimate appearance was also associated with operative treatment than with conservative treatment. The available evidence suggests that operative treatment is a safe and effective method for performing midshaft clavicular fractures.

Abstract: The application of DNA-based genetic analysis in brine shrimp (Artemia) research, stock development and management in Egypt is still not fully maximized. RAPD (Random amplified polymorphic DNA) was used to detect the general molecular polymorphism among some Artemia species collected from distantly different Egyptian locations (EMISAL at El-Fayoum, Netroun valley and EL Max Co., Alex.). The main objective of this study is to select the suitable method for reconstruction of phylogenetic relationships among the estimated Artemia species. RAPD markers were powerful tools to estimate the genetic diversity and detecting genetic polymorphism among the applied Artemia species. The number of RAPD-DNA markers (generated by ten RAPD primers) was 132 in all performed PCRs.  Out of the 132 markers, 107 were polymorphic. Some of the tested RAPD primers generated species specific DNA markers. The similarity values between each estimated Artemia species pair was relatively low.

Abstract: The Cognitive Radio (CR) can delivers the environment to Secondary Users (SUs) of Wireless Mesh Network (WMN) to utilize unused spectrum of Primary Users (PUs) opportunistically. The CR can improve the spectrum usage of the WMN. However, this rises the some additional complexities for the SUs such as spectrum heterogeneity, unpredictable PU activity and interference constraints. In this paper an analytical model has been developed to analyse these complexities for each SU node and link characteristics for end-to-end optimal Path and channel assignment. Numerical results show that the analytical model is an effective tool to investigate the effects of the PU activities and channel heterogeneity on the network performance.

Abstract: Breast cancer is a major health concern and remains the most common malignancy in women worldwide affecting 1.6%, and in Egypt 37.5%. The aim of the study was to evaluate the effect of the breast health promotion counseling on breast cancer screening behavior among female patients. Three hypotheses were addressed: 1) Increased rates in mammography, Clinical Breast Examination, Breast Self Examination, and Breast Self Examination Proficiency. 2) Increased levels of breast health knowledge perceived susceptibility to breast cancer, benefits of BSE and mammography. 3) Decreased levels of perceived barriers to BSE and mammography. Aquasi-experimental design was used. The sample consisted of 84 women who attended the counseling sessions. Data were collected through: 1) A structured interviewing questionnaire for data related to demographic characteristics; 2) pre- posttest sheet to examine the knowledge related to the problem of the breast cancer; 3)Champion’s Health Belief Model Scale (CHBMS); 4) Breast Self-Examination Proficiency Rating Instrument (BSEPRI). The counseling phase consisted of 10 sessions, given jointly with a booklet for women. Data were collected twice, at the booking visit and at the post counseling. The main results were: Improvement was observed in knowledge, changes in BSE proficiency (skills & lump detection), breast self-examination, clinical breast examination and mammography and health belief model scales in post counseling. More than half of participants between 40-45 years 34 years, 71.4% were married, 23.8%.The study concluded that the education sessions had a positive impact on knowledge and practice regarding to breast cancer. The study recommended the following that further studies may require BSE training sessions with a focus on the most essential component to achieve criterion levels of BSE skills competency.

Abstract: Global Software Engineering (GSE) is still an immature field, with palpable shortage of systematic guidelines and best practices in various contexts. This paper presents an approach that uses Soft Computing paradigm for evaluating risks in GSE context. The paper first presents a systematic hierarchical organization of the risk categories in GSE. Then, with help of empirical data, an Adaptive Neuro-Fuzzy Inference System (ANFIS) is developed to accurately assess risk for a particular GSE project. Results indicate that the framework is reliable enough to be adopted by project managers working on globally distributed projects.

Abstract: Aim of the work: to study the role of anti-mutated citrullinated vimentin (anti-MCV) in the differentiation between Rheumatoid arthritis (RA) and hepatitis C virus (HCV)-associated arthropathy among Egyptian patients. Patients and Methods: This study was conducted on two groups of patients. Group I included 25 RA patients. Group II included 25 patients with chronic HCV -associated arthropathy. Group III included 20 healthy individuals who served as a control group. Clinical Assessment included DAS 28.Laboratory investigations included rheumatoid factor (RF), anti- cyclic citrullinated peptide (anti-CCP Ab), and anti-mutated citrullinated vimentin (anti-MCV). Results: Articular involvement among HCV–associated arthropathy patients showed 9/25 (36%) patients presenting with symmetric RA-like polyarthritis. Anti-MCV was positive in 20 (80%) of RA patients and in 8 (32%) of HCV patients. There was a statistically significant difference between RA and HCV-associated arthropathy patients as regards the positivity of anti-CCP and anti-MCV (P<0.001) and (P=0.001) and also as regards the levels of anti-CCP and anti-MCV (P<0.001). Anti-MCV was significantly positively correlated with DAS 28 among patients with RA(r=0.826,P<0.001) and with viremia among patients with HCV associated arthropathy (r=0.511, P<0.01). Anti-MCV was significantly correlated with the level of Anti-CCP(r=0.664,P<0.001).ROC curve showed that the sensitivity, specificity and accuracy of anti-MCV in RA to be 80%, 80%, 84% respectively while for Anti-CCP it was 80%, 96%, 86% respectively. Multiple regression analysis between Anti-MCV and Anti-CCP as independent variables to predict RA as a dependent variable showed a non-significant effect of Anti-MCV, while a significant effect was elicited of Anti-CCP (P<0.05). In conclusion, it seems that anti-CCP is more specific and could have a better role than anti-MCV in differentiating RA patients from chronic HCV- associated arthropathy patients.

Abstract: In this paper different dimensionality reduction methods were implemented to classify eleven hand motions. Multilayer perceptron neural network MLPNN with backpropagation learning method was implemented to recognize the feature vector (FV) of surface electromyography (sEMG) signal. The highest achieved classification accuracy was 94% by implementing MLPNN and using principle component analysis (PCA) projection method based on: /RMS-EWPC/ combination features and sample entropy (SampEnt), root mean square (RMS), myopulse percentage rate (MYOP), difference absolute standard deviation value (DASDV) and energy of wavelet packet coefficients (EWPC) combination features. In order to improve the pattern recognition rate, artificial bee colony- multilayer perceptron neural network (ABC-MLPNN) was implemented instead of back propagation learning algorithm. An obvious improvement by 2% in the classification result of the hand motions was achieved when using the proposed method.

Abstract: One of the major aims to overcome tuberculosis infection is developing a vaccine that could prevent mycobacterial cells from entering macrophages and hence will be subjected to the immune defense mechanisms. MCE4A protein antigen is one of the secretory antigens that enables Mycobacteria to enter macrophages thus neutralization of such antigen will aid in the restriction of disease development. In the current study the 1200bp full length MCE4A gene was amplified and cloned in gateway entry cloning vector ( pEnter\SD\topo), then homologous recombination with the destination vector ( pDEST 40) was done in order to develop the DNA vaccine. Vaccination of guinea pigs with this DNA vaccine and subsequent challenging with M. bovis revealed comparable results with that of BCG showing that the vaccine could be promising approach to be tested on the cattle.

Abstract: Although no one can object on the significance of providing high-quality water, the process of wastewater treatment has not been given the same attention, especially in terms of the consideration of the environmental factors. In fact, several tools and techniques have been employed by Wastewater Treatment Plants (WWTPs) for the purpose of improving the efficiency of the treatment process itself. The tool of Data Envelopment Analysis (DEA) can be considered as one of the useful approaches that have been employed in several studies within the context of wastewater treatment. The purpose of this paper is to develop a DEA model for the purpose of measuring the efficiency for a set of WWTPs. Eight different WWTPs located within one of the largest countries in the Middle East were investigated. The proposed DEA model was formulated using four inputs and two outputs. The four Inputs include electricity consumption, number of engineers, number of technicians, and number of workers. The two outputs were the percentage of the removed chemical oxygen demand (COD) and the percentage of the removed suspended solids (SS). Data were analyzed and the results were generated using specialized software for DEA. The results revealed that three out of the eight WWTPs were inefficient. In general, the flexibility of DEA adds a sort of competitive advantage over other tools and techniques.

Abstract: This study aims to investigate the histological alteration in skin, gills, liver and muscle as well the ultrastructure alteration in the liver of Siganus canaliculatus (S. canaliculatus) and Epinephelus morio (E. morio )caught from different sites at Jeddah and Yanbou coast as a bio-indicator for oil pollution. Skin, gills, Livers and muscle of ten fishes of a similar size of each Siganus canaliculatus and Epinephelus morio were used in this study. Tissues samples were immediately taken and prepared for histopathological and ultrastructure alterations investigation. Such alterations were high in fishes collected from the polluted sites either from Jeddah or Yanbu when compared with their corresponding fishes collected from the reference sites. Fishes collected from Jeddah were more polluted than that collected from Yanbu. The highest affected organ was the skin followed by the gills and liver, while the muscles were the lowest ones. Moreover S. canaliculatus fishes were seriously affected than E. morio. The E. morio is highly resistant than S. canaliculatus. The present study indicates that S. canalicu
