abstract listening is a key and main tool in second language skill and its development is of prime concern to teachers and learners. furthermore, the application of technology in language classrooms has become more commonplace in the last fifty years. computer and the internet have made foreign language materials easy to access and use. so, the present study is an attempt to examine the effec...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
امروزه شیمی محاسباتی، ساختار ، خواص مولکول ها و واکنش های شیمیایی را به دو روش نظری ساختار الکترونی و مکانیک مولکولی بر اساس قوانین فیزیکی به صورت عددی شبیه سازی می کند. بر این اساس، در این تحقیق با استفاده از روش ساختار الکترونی یک سطح انرژی پتانسیل چهار بعدی برای سامانه cs2-cs2 با محاسبات از اساس، انرژی برهم کنش برای پیکربندی های مختلف به دست آمده است. برای این کار از روش ابر مولکول و سطح محا...
Objectives—A prospective cohort study was initiated to clarify whether the current level of exposure to carbon disulphide (CS2) is low enough to prevent occurrence of subclinical health impairments or to ameliorate health eVects due to past high exposure. This paper describes the eVects of exposure to CS2 on the nervous and endocrine systems, and the subjective symptoms in a baseline observatio...
A historical cohort study of the morbidity of CS2 and control workers was carried out in a viscose rayon factory and an adjacent cotton mill. A total of 725 male workers was employed at the two factories on I May 1966. All records of medical treatment received by these men from general practitioners, hospitals, and plant clinics for the period from I May 1966 to 31 December 1970 were obtained f...
Records of blood pressure and body weight of CS2 workers were analyzed in relation to the levels of CS2 exposure at a Japanese rayon-producing fac tory. A cohort of 46 CS2 workers who had later been transferred to non-CS2 jobs showed first a statistically significant rise, which was then followed by two consecutive episodes of statistically significant falls in systolic blood pressure. These ep...
Carbon disulfide (CS2) has been historically associated with the production of rayon, cellophane, and carbon tetrachloride. This study identifies multiple mechanisms by which CS2 contributes to the formation of CO2 in the atmosphere. CS2 and other associated sulfide compounds were found by this study to be present in emissions from unconventional shale gas extraction and processing (E&P) operat...

the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Arsenic (As) is a well-known toxic metalloid found naturally and released by different industries, especially in developing countries. Purple nonsulfur bacteria (PNSB) are known for wastewater treatment and plant growth promoting abilities. As-resistant PNSB were isolated from a fish pond. Based on As-resistance and plant growth promoting attributes, 2 isolates CS2 and SS5 were selected and ide...
