abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
Background & Objectives : Currently, work-related musculoskeletal disorders are a major occupational health concern. This study tried to evaluate the risk factors of musculoskeletal disorders by the assessment of repetitive tasks (ART). It also sought to determine the effects of an ergonomic intervention on the mentioned risk in a manufacturing company . Methods: In this study, 6...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

Background:Human reliability assessment consists ofusing quantitative and qualitative methods to predict human contribution to the occurrence of error;so, using reliability assessment techniques is necessary to prevent and limit the consequences of errors in sensitive work environments.Healthcare considers as the high-risk areas.With due attention to the high rates of cesarean section in Iran, ...
background: programming and planning an appropriate structure for internship and purposeful assessments of students play a considerable role in developing their practical and theoretical knowledge level. one of the suitable alternatives for the traditional method is assessing internship through objective structured clinical examination (osce). therefore the aim of the present study is to perfor...
objective: generalized anxiety disorder is one of the most common anxiety disorders in the general population. several studies suggest that anxiety sensitivity is a vulnerability factor in generalized anxiety severity. however, some other studies suggest that negative repetitive thinking and experiential avoidance as response factors can explain this relationship. therefore, this study aime...
in this paper, we proposed an algorithm for solving the problem of task scheduling using particle swarm optimization algorithm, with changes in the selection and removing the guide and also using the technique to get away from the bad, to move away from local extreme and diversity. scheduling algorithms play an important role in grid computing, parallel tasks scheduling and sending them to appr...

Background: today, musculoskeletal disorders are considered as a serious threat for workers, and one of the main activities, which leads to these problems, is lifting tasks. Moreover, workers in printing industry are widely involved in inappropriate postures and lifting loads. The aim of this study was to compare the results of assessment of lifting tasks with KIM-LHC, WISHA and Snook tables in...
background: wolf motor function test (wmft) is used in the assessment of upper extremity motor function in stroke patients. this scale contains 15 items and assesses joint-segment movements and functional tasks. objectives: translation and assessment of internal consistency and reliability of the persian version of wmft in iranian stroke patients. materials and methods: after translation (based...
