the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Land cover is one of basic data layers in geographic information system for physical planning and environmentalmonitoring. Digital image classification is generally performed to produce land cover maps from remote sensing data,particularly for large areas. In the present study the multispectral image from IRS LISS-III image along with ancillary datasuch as vegetation indices, principal componen...
The optimal management of ground water consumption is impossible without proper knowledge of water distribution, aquifer territories, and water table fluctuations. Humans are faced with the problem of water scarcity, due to various reasons such as population growth, droughts and reduced rainfall, and industrial progress and its impact on water resources. The purpose of this study was to determi...
Subalpine ecosystems are highly fragile as compared to biological andenvironmental factors. Landslide is one of the ruinous upshots of this ecosystem. One of theimpressionable areas in the cause of natural factor is Masoleh watershed in western AlborzMt, (Iran). In order to landslide hazard zonation, landslide index and frequency ratio methodbased on twelve causative factors such as slope, slop...
There are more than 750 counties in 13 provinces and autonomous regionsconstituting 30% of China lands which are facing serious problem of desertification. Theseareas are mainly distributed in arid, semi-arid and dry sub-humid areas in the western part ofNortheast China, North central china and most of northwest china. Biological methods are theultimate way for drift sand stabilization and a fu...
چکیده این تحقیق " مواد درسی " را به عنوان یکی از بحث برانگیزترین موضوعات آموزش زبان تلقی کرده و درتلاش است به سه سوال عمده پاسخ دهد: 1) آیا بکارگیری جزوات گرداوری شده توسط گروهی از مدرسین تاثیر بسزایی در میزان توانش خواندن و درک متون انگلیسی دانشجویان پزشکی دارد؟ 2) آیا استفاده از مواد درسی اصلی( بین المللی )، توانش خواندن و درک متون انگلیسی دانشجویان پزشکی را به طور چشمگیری تحت تاثیر قرار م...
