    In the present study, the effect of density on transportation stress in Mesopotamichthys sharpey fingerlings was evaluated. For this purpose, four different densities, including 40, 80, 120 and 160 g/l were used as treatments each with 3 replicates. Simulation of transport procedure was carried out for 4 hrs. The blood samples were collected from the fish prior to loading from the stocking tank (control), after 4 hrs of transportation and from released fish into recovery glass tanks at 6, 12, 24, 48 and 96 hrs after transportation during recovery period. For blood sampling, fish immediately anesthetized by adding 2% 2-phenoxy ethanol and the blood samples were prepared. The cortisol, glucose and lactate value of plasma were measured. The results showed a significant increase in cortisol and glucose levels (in highest density) after transportation in all treatments (P0.05). The results showed that only cortisol level was significantly different with basal level at 96 hrs. Our findings showed that this species can be transported at higher densities up to 120 g/l

    Background and aims: Electrocoagulation is an electrochemical method for the treatment of water and waste water. Water disinfection by electrochemical methods has been increasingly carried out recently. The aim of this applied research is to investigate the removal of E. coli and S. aureus bacteria from drinking water by using Electrocoagulation (EC) - Electroflotation (EF) with Stainless Steel - Graphite felt electrodes parallel with the monopole mode. Methods: An experimental study was conducted in a batch system. In this study, the contaminated water samples were prepared by adding104, 105 and 106 CFU/ml E. coli and S. aureus. Independent variables Including: different concentrations of E.coli and S. aureus bacteria (104, 105 and 106 CFU/ml), reaction time (5, 10, 15 and 20 min), initial pH (7, 8 and 9), electrode gap (1, 2 and 3 cm), current density (0.83, 1.67 and 3.3 mA/cm2) to determine the optimum conditions were investigated. One-way ANOVA was used to analyze the results. Results: The results show that in the optimum conditions with increasing the pH from 7 to 9 removal efficiency of bacterial strains of E.coli and S. aureus were decreased significantly from 100% to 80% and 100% to 83%, respectively. In initial concentration of 105 CFU/ml, optimum conditions were obtained for current density, reaction time and electrodes gap; 3.3 mA/cm2, 20 min and 2 cm, respectively. Conclusion: According to the results, E.coli and S. aureus removal efficiency in optimum conditions was obtained, 100%. Thus, the EC/EF process can be used for removal of pathogenic bacteria from drinking water

    Background: Multiple sclerosis (MS), a chronic disease of the central nervous system (CNS), causing progressive nerve damage, has disabling symptoms, and undermines self-efficacy beliefs. Due to the importance of self-efficacy modified in adaptation and coping with stress, this study was conducted with the aim to investigate the effect of emotional intelligence training on self-efficacy in women with MS. Materials and Methods: This randomized clinical trial was conducted on 70 women referring to the Multiple Sclerosis Clinic of Kashani Hospital, Isfahan, Iran. The participants were randomly assigned to two groups through minimization method. In the experimental group, emotional intelligence training was performed within 8 weeks, once a week for 90 minutes, in groups of 8–9 individuals. Data were collected using the Multiple Sclerosis Self-efficacy Scale (MSSS) before, immediately after, and 3 months after the intervention in both groups. Data were analyzed using independent t-test and repeated measures ANOVA in SPSS. Results: The results of independent t-test showed no significant difference between the groups in terms of mean self-efficacy scores before the intervention (p > 0.05). However, there was a significant difference between the groups in this regard immediately after and 3 months after the intervention (p < 0.05). Repeated measures ANOVA showed a significant difference in the mean score of self-efficacy and its components between the groups at different times (p < 0.05). Conclusions: It seems that emotional intelligence training is effective on the improvement of self-efficacy of women with MS. Hence, this method can be recommended as an effective and affordable technique

    Objective: The aim of this study was investigating the effect of 12 weeks of yoga and aerobic exercise (running on a treadmill) on the sleep quality in women with Type 2 diabetes. MATERIALS AND Methods: 39 diabetic women were selected from Semnan city with the mean age of 46.85±3.35 years, weight of 69.79±17.18 kg, height of 155.03±5.00, BMI of 29.64±5.00 kg/m2 who had a background of diabetes for 6.46±2.69 years. They were then randomly divided into yoga exercise (n=15), aerobic exercise (n=13), and control group (n=11). The exercise program was performed for 12 weeks, three sessions per each week. In order to measure the sleep quality, the Pittsburgh Sleep Quality Index (PSQI) was used. The data were analyzed by non-parametric wilcoxon and Kruskal-Wallis Test at significance level of p<0.05. Results: Overall score of sleep quality improved after six (p=0.001) and 12 (p=0.001) weeks of yoga exercise. Also, significant effect was observed after 6 weeks of aerobic exercise (p=0.039). However, the positive effect was diminished to under significant levels after 12 weeks of aerobic exercise (p=0.154). Kruskal-Wallis Test showed significant differences between yoga and aerobic groups after 12 weeks of exercise (p=0.002). No significant differences were observed in control groups in all situation. Conclusions: It can be concluded that yoga exercise is more effective in improving the sleep quality in comparison with the same course of aerobic exercise in women suffering from diabetes Type 2. Thus, yoga exercise can be suggested to these patients

    One of the most important challenges in the field of robotics is robot manipulators control withacceptable performance, because these systems are multi-input multi-output (MIMO), nonlinearand uncertainty. Presently, robot manipulators are used in different (unknown and/orunstructured) situation consequently caused to provide complicated systems, as a result strongmathematical theory are used in new control methodologies to design nonlinear robust controllerwith acceptable performance (e.g., minimum error, good trajectory, disturbance rejection).Classical and non-classical methods are two main categories of robot manipulators control,where the conventional (classical) control theory uses the classical method and the non-classicalcontrol theory (e.g., fuzzy logic, neural network, and neuro fuzzy) uses the artificial intelligencemethods. However both of conventional and artificial intelligence theories have applied effectivelyin many areas, but these methods also have some limitations. This paper is focused on review offuzzy logic controller and applied to PUMA robot manipulator
