In this paper the impacts of utilizing WT in improving technical constraints of the reconfigurable distribution system has been evaluated. The Monte Carlo based power flow equation is implemented to the presented scheduling problem. Simulations are done on IEEE 33 bus reconfigurable distribution system

ABSTRACT: In this study, free and forced vibration analysis of nano-composite rotating pressurized microbeam reinforced by carbon nanotubes (CNTs) under magnetic field based on modify couple stress theory (MCST) with temperature-variable material propertiesis presented. Also, the boundary conditions at two ends of nano-composite rotating pressurized microbeam reinforced by CNTs are considered as simply supported. The governing equations are obtained based on the Hamilton's principle and then computed these equations by using Navier's solution. The magnetic field is inserted in the thickness direction of the nano-composite microbeam. The effects of various parameters such as angular velocity, temperature changes, and pressure between of the inside and outside, the magnetic field, material length scale parameter, and volume fraction of nano-composite microbeam on the natural frequency and response systemare studied. The results show that with increasing volume fraction of nano-composite microbeam, thickness, material length scale parameter, and magnetic fields, the natural frequency increases. The results of this research can be used for optimization of micro-structures and manufacturing sensors, displacement fluid, and drug delivery. Keywords: Forced vibration analysis, Nano-composite rotating pressurized microbeam, Carbon nanotubes, Modify couple stress theory, Temperature-variable material properties

The Reinforcement Sensitivity Theory of Personality has as its main foundation a Behavioural Inhibition System (BIS), defined by anxiolytic drugs, in which high trait sensitivity should lead to internalising, anxiety, disorders. Conversely, it has been suggested that low BIS sensitivity would be a characteristic of externalising disorders. BIS output should lead to increased arousal and attention as well as behavioural inhibition. Here, therefore, we tested whether an externalising disorder, Attention Deficit Hyperactivity Disorder (ADHD), involves low BIS sensitivity. Goal-Conflict-Specific Rhythmicity (GCSR) in an auditory Stop Signal Task is a right frontal EEG biomarker of BIS function. We assessed children diagnosed with ADHD-I (inattentive) or ADHD-C (combined) and healthy control groups for GCSR in: a) an initial smaller study in Dunedin, New Zealand (population ~120,000: 15 control, 10 ADHD-I, 10 ADHD-C); and b) a main larger one in Tehran, Iran (population ~9 [city]-16 [metropolis] million: 27 control, 18 ADHD-I, 21 ADHD-C). GCSR was clear in controls (particularly at 6–7 Hz) and in ADHD-C (particularly at 8–9 Hz) but was reduced in ADHD-I. Reduced attention and arousal in ADHD-I could be due, in part, to BIS dysfunction. However, hyperactivity and impulsivity in ADHD-C are unlikely to reflect reduced BIS activity. Increased GCSR frequency in ADHD-C may be due to increased input to the BIS. BIS dysfunction may contribute to some aspects of ADHD (and potentially other externalising disorders) and to some differences between the ADHD subtypes but other prefrontal systems (and, e.g. dopamine) are also important.

Background: Depression is one of the most common mental illnesses. Few studies have investigated the association between dietary patterns and depression in developing countries. Objective: The aim of this study was to determine the association between dietary patterns and depressive symptoms in adult women living in Tehran in 2013. Methods: This cross-sectional study was carried on 217 women aged 20-45 years attending health centers in the north and west of Tehran in 2013. The subjects were selected by systematic cluster sampling method. Data were collected through demographic, food frequency, and physical activity questionnaires and the beck depression inventory. Major dietary patterns were identified by factor analysis and their association with depressive symptoms was assessed by logistic regression analysis. Findings: The prevalence of depressive symptoms was 63.2% in the studied women. Two major dietary patterns were identified (healthy and unhealthy). After adjusting for confounders, subjects with higher scores in the unhealthy dietary pattern had higher odds (OR=2.21, P=0.01) of depressive symptoms; but the healthy dietary pattern was not associated with depressive symptoms. Conclusion: With regards to the results, it seems that the unhealthy dietary pattern is associated with the risk of depression in women.

Aims: The present study was done with aim to predict the cognitive and motivational functions of sports imagery based on age, visual and motor imagery ability in Iranian veteran basketball players. Materials & Methods: This descriptive-correlational study was done on 40 veteran basketball players participating in the national championship in 2007 in Shiraz who were selected by census method in 2007. The research tools were demographic, motor imagery (VMIQ), visual imagery (VVIQ) and sport imagery (SIQ) questionnaires. Data analyzed using SPSS16 software. Relation between variables was evaluated using the Spearman correlation coefficient and regression equation for each stage. Findings: The age variable was correlated with motivational specific imagery functions, motivational-arousal general, motivationشal-experts general and sports imagery generally. The highest mean of the scores belonged to motivational specific imagery and lowest mean scores belonged to the cognitive general imagery. Visual imagery ability (with open eyes) for the motivational specific imagery function had also predictive role. Conclusion: There is a correlation between sport imagery functions with age and the visual imagery ability with open eyes. Sport imagery functions (motivational specific, motivational-expert general and motivational-arousal general) are predicted based on age, which means that with increasing the age the use of these functions decreases. Also, by reducing imagery with open eyes, motivational specific function is reduced.

Introduction: Bioaeroslos released from wastewater treatment plants may contain pathogens existing in the sewage which could endanger the health of workers. The aim of this study was to evaluate the status of bioaerosol emissions form in a sanitary wastewater treatment plant. .Material and Method: This cross-sectional study was carried out in different units of a sanitary wastewater treatment plant. For this purpose, air samples were collected on blood agar and dextro agar in an Andersen single-stage sampler with flow of 28.3 lit/min for 10 minutes. Collected samples were shipped to the lab immediately and incubated for 48 hours. Then, incubated samples were counted for colonies concentration. .Result: Based on the result of this study, the mean density of bacterial and fungal bioaerosols in all wastewater treatment plants were 412.86±23.30 and 53.72±23.99 CFU/m3, respectively. Microbial contamination of the air within a kilometer away from the site (control areas) was 17 times less than its average density. .Conclusion: Wastewater treatment processes can contaminate the air surrounding the plant, particularly with bacteria bioaerosols. Therefore, it is necessary to control the emissions and protect the health of workers against risks arising from exposure to bioaerosols.

The main goal of this paper is focused on comparison of influence of drug therapy and neurofeedback training on reduction of anxiety symptoms and life quality of generalized anxiety disorder (GAD) patients. For this purpose, 16 visitors in one of psychiatry centers in Tehran were studied who received GAD diagnosis and did not suffer other psychological disorders according to psychiatrist visit and diagnostic criteria within fourth edition of statistical and diagnostic guide revised text of psychological disorders )DSM-IV-TR( (8 persons in neurofeedback training and 8 ones in drug therapy). Patients in both groups were surveyed and studied in pre-test and post-test steps through GAD seven-question scale (GAD-7) and life quality questionnaire (PWI-A). Persons in neurofeedback training group received fifteen 30-minute sessions (three sessions per week) on alpha wave increase and those in drug therapy were treated under supervision of physicians by anti-anxiety drugs (SSIRs) for one year. Record and training of alpha wave activity was accomplished in O1 or O2 and patients received audio feedback for increase of alpha range up to higher than determined threshold. Wilcoxon and Mann Witney tests were applied for descriptive analysis of data. Research findings show that neurofeedback training led to increase of alpha wave in the receiver group. In addition, influence of neurofeedback training on reduction of GAD symptoms in this group is considerably higher than that of drug therapy group. There was no meaningful difference between the two groups on change of patients' life quality index.

To compare the efficacy of common drug therapy (Methadone or Boprenorphine maintenance) with a combination of neuro-feedback and drug therapy in opiate-dependant patients for overcoming opiate cravings, twenty volunteer male subjects (with the mean age of 30) participated in Methadone or Boprenorphine maintenance drug therapy. This was an experimental study with pretest-posttest design, in which “Heroin Craving Questionnaire” was administered to the sample to collect the data. Homogeneous subjects were assigned to two experimental and control groups. The former received drug therapy and neuro-feedback training, while the latter only underwent drug therapy. The training included SMR on Cz followed by an alpha-theta protocol on Pz during thirty sessions for five weeks (six sessions each week). Multivariate analysis of covariance (MANCOVA) indicated that the anticipation of positive outcome, desire to abuse substance and relief from withdrawal (dysphoria) significantly decreased in the experimental group compared to the control one. It can be concluded that neure-feedback was effective on reducing the intensity of opiate craving of the addicted patients.

Background and aims Bioaerosol exposure is associated with a vast range of adverse health effects including infectious diseases, acute toxic effects, allergy and cancer. This study was conducted to determine type and concentration of bioaerosols in ambient air of educational hospitals. Methods In this cross-sectional study, different wards of 5 educational hospitals including nurse station, patient room, isolation room and operation room were investigated. Totally, 300 air samples were taken based on NIOSH standard method. Blood agar and malt extract agar were used as sampling media. Andersen single-stage sampler with flow of 28.3 lit/min was applied for air sampling. The average sampling time was 10 minutes. Soon after air sampling, samples were shipped to lab and incubated for 48 hours. Then, incubated samples were counted for colonies. Concentration was determined in CFU/m 3 . Results the highest and the lowest concentrations were observed in patient room andoperation room, respectively. In spite of sterilization, different types of fungi (i.e. Aspergillus niger) and gram-positive bacteria are seen in samples. The results showed that in all hospitals the concentration in all wards were higher than 30 CFU/m 3 as the suggested value. Conclusion Concentrations of bioaerosols in all hospitals studied were higher than the suggested value. For reducing bioaerosol exposure, standard ventilation system should be designed and utilized.

For detailed explanation of the experimental results of lepton production cross section in hadronic collisions such as nucleon-nucleon or nucleon-nuclei, it is of great importance to use quarks and sea quarks distribution function inside free and bound nucleons. In this paper, the role of pion cloud inside the nucleus in the structure function of Cu and Pt nuclei and the EMC ratio of these nuclei were investigated by using harmonic oscillator model. Then, in the framework of the Drell-Yan process and conventional nuclear theory, GRV’s quarks distribution functions and pionic quarks distribution functions were used to calculate lepton and antilepton production cross section in p-Cu and p-Pt scattering. From the results and based on the mentioned model, by considering pionic contribution, the theoretical results are improved.

Objective: One of the major problems of all ceramic restorations is their probable fracture against the occlusal force. The aim of the present in-vitro study is was to compare the effect of two marginal designs (chamfer & shoulder) on the fracture resistance of zirconia copings, CERCON (CAD/CAM). MATERIALS AND METHODS: This in vitro study was done with single blind experimental technique. One stainless steel dye with 50’ chamfer finish line design (0.8 mm depth) was prepared using milling machine. Ten epoxy resin dyes were made, The same dye was retrieved and 50' chamfer was converted into shoulder (1 mm).again ten epoxy resin dyes were made from shoulder dyes. Zirconia cores with 0.4 mm thickness and 35 µm cement Space fabricated on the20 epoxy resin dyes (10 samples chamfer and 10 samples shoulder) in a dental laboratory. Then the zirconia cores were cemented on the epoxy resin dyes and underwent a fracture test with a universal testing machine (GOTECH AI-700LAC, Arson, USA) and samples were investigated from the point of view of the origin of the failure. RESULT: The mean value of fracture resistance for shoulder margins were 788.90±99.56 N and for the chamfer margins were 991.75±112.00 N. The student’s T-test revealed a statistically significant difference between groups (P=0.001). CONCLUSION: The result of this study indicates that marginal design of the zirconia cores effects on their fracture resistance. A chamfer margin could improve the biomechanical performance of posterior single zirconia crown restorations. This may be because of strong unity and round internal angle in chamfer margin.

The electric solar wind sail (E-sail) is a space propulsion concept that uses the natural solar wind dynamic pressure for producing spacecraft thrust. In its baseline form, the E-sail consists of a number of long, thin, conducting, and centrifugally stretched tethers, which are kept in a high positive potential by an onboard electron gun. The concept gains its efficiency from the fact that the effective sail area, i.e., the potential structure of the tethers, can be millions of times larger than the physical area of the thin tethers wires, which offsets the fact that the dynamic pressure of the solar wind is very weak. Indeed, according to the most recent published estimates, an E-sail of 1 N thrust and 100 kg mass could be built in the rather near future, providing a revolutionary level of propulsive performance (specific acceleration) for travel in the solar system. Here we give a review of the ongoing technical development work of the E-sail, covering tether construction, overall mechanical design alternatives, guidance and navigation strategies, and dynamical and orbital simulations.
