abstract the present study deals with a comparison between reactive and pre-emptive focus-on-form in terms of application and efficiency. it was conducted in an intermediate english class in shahroud. 15 male learners participated in this research and their age ranged from 18 to 25. a course book, new interchange 3, and a complementary book were used. every session the learners gave lectures o...
موضوع: پوکی استخوان به عنوان شایعترین بیماری متابولیک استخوان،یکی از عوامل مهم ایجاد کایفوز پشتی ستون فقرات و افزایش احتمال خطر سقوط است. استفاده از ارتزها یکی از روش های درمانی است که در خصوص ارزشمندی آنها برای بهبود تعادل اتفاق نظر وجود ندارد. هدف از انجام این مطالعه بررسی تاثیر ارتز وزنه دار کایفوز بر میزان خطر سقوط در زنان مبتلا به پوکی استخوان اولیه بود. روش بررسی: طی یک مطالعه کارآزمائ...
coccinellids play a major role in aphid control. hippodamia variegata goeze is an aphidophagous predator of worldwide distribution that could be found in different parts of iran. one of the criteria for evaluating the efficiency of a predator is its response to change in prey population density (functional response). the functional responses of males and females of hippodamia variegata were stu...
Data envelopment analysis (DEA) is a technique for measuring the efficiency of decision making units. In all models of the DEA, for each unit under assessment, the numerical efficiency is obtained which may be less than or equal to one. Given the possible large number of functional units, we use various ranking methods for evaluating units. One of the rating methods is Balance index and Topsis....
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
Background and Objectives: Productivity and efficiency are the most important and the most common mechanisms of evaluation and measurement of the performance of an enterprise including the Social Security Organization. In the past decades, performance evaluation of various economic sectors has been attractive to researchers in different disciplines. Thus, the aim of this study was to measure th...
