The limited number of resources in Wireless sensor Networks (WSNs) and long communication distance between sensors and base station causes high energy consumption and consequently reduce the network lifetime. Therefore one of the important parameters in these networks is the optimized energy consumption. One way to reduce the energy consumption is to cluster the network. In this study, a dynamic clustering method is presented based on the artificial bee colony and the genetic algorithm. In fact, the genetic algorithm is used for determining the cluster heads and the artificial bee colony algorithm is used for determining member nodes in each cluster. The proposed algorithms were simulated by OMNeT++simulator. Simulation results showesome improvements. © 2017 IEEE.

Despite the importance of this issue, less has been paid to the influence of exercise on the neural side effects of anabolic androgenic steroids and mechanisms. We investigated the effects of two levels of endurance exercise on neurodegeneration side effects of nandrolone. The study period was 8 weeks. Wistar rats were divided into nine groups including the control (CTL) group, mild exercise (mEx) group, and vehicle (Arach) group which received arachis oil intramuscularly, nandrolone (Nan) group which received nandrolone decanoate 5 mg/kg two times weekly, mEx+Arach group which treated with arachis oil along with mild exercise, mEx+Nan group which treated with nandrolone along with mild exercise, severe exercise (sEx) group, sEx+Arach, and sEx+Nan groups. Finally, brain samples were taken for histopathological, biochemical, and western blot analysis. Nandrolone significantly decreased the intact cells of the hippocampus, total antioxidant capacity (TAC) (P < 0.05 versus CTL and Arach groups), TAC to malondialdehyde ratio (TAC/MDA), and Bcl-2. Nandrolone increased the Bax/Bcl-2 ratio of the brain tissue (P < 0.01 versus CTL and Arach groups). Combination of mild exercise and nandrolone rescued the intact cells to some extent, and this effect was associated with the improvement of Bcl-2 level and Bax/Bcl-2 ratio of brain tissue. Combination of severe exercise and nandrolone rescued the intact cells and improved the TAC, TAC/MDA, and Bax/Bcl-2 ratios. The findings suggest that low- and high-intensity endurance exercise decreased the risk of neurodegeneration effect of nandrolone in the hippocampus of rats. This effect can be explained by the regulation of the redox system and cell homeostasis. © 2017, Springer Science+Business Media New York.

Reproductive management has an important role in animal production; therefore, the objective of this study was to determine the effect of different dosages of equine chronic gonadotropin (eCG) on reproductive performance of mature Raini goats during the breeding season. One hundred Raieni goats (42±2.5 kg) were randomly allocated to five groups to receive different dosages of eCG; (0 IU as control group; and other treated groups received 350, 450, 550 and 650 IU of eCG respectively). The interval to onset of estrus was detected by using five aproned bucks. Oestrus was induced by prostaglandin and occurred 24 to 48 h after the second injection. The results showed the estrus incidence rates were not significantly different between groups (p>0.05). The pregnancy rates were 90, 90, 95, 100 and 85% in treatments and control group, respectively, with the pregnancy rate in 550 and 650 IU groups being significantly higher than the other groups (p<0.05). Twinning rates were higher in treated goats (55, 58 and 65%) than in controls (36%, p<0.05). The results of the present study show that eCG treatments increase the twinning rate in Iranian Raieni goats. © 2012 Academic Journals Inc.

This study was conducted to evaluate the male effect on the manifestation of estrus and feeding behavior of Afshari ewes during their breeding season. The study consists of 48 Afshari ewes, 3 years old, 67 ± 2 kg live weight, body condition score 3, along with 10 Afshari rams. The study was for a period of 6 weeks in a complementary randomized design. Ewes were equally divided into three treatments (T1, T2, and T3) along with a control (T4) with six animals in each group. Variable factors of treatments was the distance of the ram box (from the ewes), which was determined to be the T1 (0–5 m), T2 (10–15 m), and T3 (25–30 m). Exposure of the ewes to the rams resulted in an earlier manifestation of estrus signs (p < 0.05). Moreover, the total recorded estrus signs were significantly affected by the distance from the rams (p < 0.05). The result of this study showed differences in feed intake of the ewes due to the distance from the rams (p < 0.05). In the other words, the distance of the ewes from the rams significantly affected feed intake of the Afshari ewes. © 2014, Springer Science+Business Media Dordrecht.

The next-generation networks should provide users with highly intelligent and integrated services and applications. From the other hand, the increasing numbers of users and services have made the integrated management of the networks complicated. Still traditional management systems are not efficient enough and the heterogeneity and complexity of next-generation networks causes many challenges in network management. Therefore network operators and service providers have to provide users with high quality services. This paper reviews the challenges of management in next-generation networks and the proposed solutions. © 2013 Springer-Verlag.

Spectral transformation methods, including correlation coefficient (CC) and Optimum Index Factor (OIF), band ratio (BR) and principal component analysis (PCA) were applied to ASTER and Landsat TM bands for lithological mapping of Soghan ophiolitic complex in south of Iran. The results indicated that the methods used evidently showed superior outputs for detecting lithological units in ophiolitic complexes. CC and OIF methods were used to establish enhanced Red-Green-Blue (RGB) color combination bands for discriminating lithological units. A specialized band ratio (4/1, 4/5, 4/7 in RGB) was developed using ASTER bands to differentiate lithological units in ophiolitic complexes. The band ratio effectively detected serpentinite dunite as host rock of chromite ore deposits from surrounding lithological units in the study area. Principal component images derived from first three bands of ASTER and Landsat TM produced well results for lithological mapping applications. ASTER bands contain improved spectral characteristics and higher spatial resolution for detecting serpentinite dunite in ophiolitic complexes. The developed approach used in this study offers great potential for lithological mapping using ASTER and Landsat TM bands, which contributes in economic geology for prospecting chromite ore deposits associated with ophiolitic complexes. © 2014 COSPAR.

Podiform chromite ore deposits in ultramafic parts of ophiolite rock complexes can be detected using remote sensing data. This study focuses on the discrimination of chromite bearing mineralized zones using Landsat TM and Advance Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite data in Abdasht ophiolite complex, south of Iran. Several image processing methods, including Log residual, Decorellation Stretch, Band ratio and Mixture-Tuned Matched-Filtering (MTMF) have been evaluated for lithological mapping using Landsat ETM and ASTER data. The outcome showed that TIR band ratios of ASTER can discriminate quartzite, carbonate and mafic-ultramafic rocks in the ophiolite complex. Log residual, Decorollation Stretch and MTMF methods were more capable than previous published ASTER methods specifically for lithological mapping at a regional scale. New geological map of Abdasht region was produced based on the interpretation of ASTER image processing results and field verification. Consequently, the proposed methods demonstrated the ability of ASTER and Landsat ETM data to provide information for detecting chromite host rock (serpentinized dunites) that is valuable for chromite prospecting in study area. Additionally, the techniques used in this study are subtle for exploration geologist and mine engineering to identify high-potential chromite-bearing zones in the ophiolite complex, minimizing costly and time-consuming field works. © 2013 Saudi Society for Geosciences.

Mental disorders are a very common health problem among adolescents. The purpose of this study was to determine the prevalence of mental disorders in high school adolescents in the city of Bandar Abbas in the 2012 academic year. In this study, the cluster sampling method was used to select 800 subjects from the student population of the high school, and a survey of their mental health was conducted by using the SCL-90-R questionnaire. The survey results were used to identify students who were suspected of having a mental disorder, and those students were evaluated using an interview method based on DSM-IV. The results showed that 16.7% of the 800 students included in the study had some mental disorder. Anxiety and mood disorders were the most prevalent mental disorders observed, with prevalence percentages of 85% and 39%, respectively. Among the demographic variables, 22% of the girls and 11% of the boys had some disorder. There were significant relationships between the mental disorders of the adolescents and a number of variables, including a family history of mental disorders, the occurrence of divorce in their families, drug addiction, and alcohol consumption. Mental disorders in the city of Bandar Abbas were more prevalent among adolescent girls than boys, and specific anxiety disorders, such as anxiety, obsessive-compulsive disorder, and depression, occurred more frequently than other mental disorders. Mental disorders were more prevalent among students from families in which there was a family history of mental disorders, divorce, drug addiction, and alcohol consumption.

Introduction: Mental health issues are common in Iran. This study examined the impact of praying and fasting on the mental health of students attending the Bandar Abbas Branch of Islamic Azad University in Iran in 2012. Methods: A total of 200 undergraduate students (85 girls and 115 boys) at the Bandar Abbas Branch of Islamic Azad University were selected as the sample using a multi-stage cluster random sampling process. The GHQ-28 mental health questionnaire was administered to them 2 weeks before Ramadan as a pre-test and 2 weeks after Ramadan as a post-test. Results: After analyzing data using a one-way ANOVA test and t-test, it was revealed that people who fasted the whole month of Ramadan or most of it, even they did so just for amusement, received more favorable scores on all the mental health subscales; meanwhile, reduced scores were evident after Ramadan among those who did not fast at all or, due to religious or medical reasons, could not fast. In addition, people who always or usually prayed also received higher scores on the mental health subscales. Conclusion: The results of this study indicate that fasting, even for amusement purposes, enhances individuals' mental health. In addition, people who always or usually pray have higher mental health scores than those who never or rarely pray.
