the effects of keyword and context methods on pronunciation and receptive/ productive vocabulary of low-intermediate iranian efl learners: short-term and long-term memory in focus
از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولPhysical Evaluation of Biodegradable Films of Calcium Alginate Plasticized with Polyols
The influence of different polyols as plasticizers of alginate films on their physical attributes like moisture content, soluble mass in water, water uptake, water vapor permeability, opacity and mechanical properties were determined and the results discussed based on scanning electron microscopy observations and glass transition temperature. The alginate films were obtained by casting, using t...
متن کاملShort-Term and Long-Term Effects of Kinesio-Taping on Pain and Functional Stability in Swimmers With Shoulder Impingement Syndrome
Purpose: Kinesio-taping (KT) is a new therapeutic approach for shoulder impingement syndrome (SIS), which is common in swimmers. This study was performed to investigate the short- and long-term effects of KT on shoulder pain and functional stability in swimmers with SIS. Methods: In this quasi-experimental study (randomized control trial), 28 swimmers with SIS were randomly allocated to the ta...
متن کاملLong-term stability analysis of goaf area in longwall mining using minimum potential energy theory
Estimation of the height of caved and fractured zones above a longwall panel along with the stability conditions of the goaf area are very crucial to determine the abutment stresses, ground subsidence, and face support as well as designing the surrounding gates and intervening pillars. In this work, the height of caving-fracturing zone above the mined panel is considered as the height of destre...
متن کاملStrong Improvement of Long-Term Chemical and Thermal Stability of Plasmonic Silver Nanoantennas and Films.
Silver (Ag) nanostructures and thin films are advantageous plasmonic materials as they have significantly lower losses than gold (Au). Unfortunately, Ag nanostructures suffer from poor chemical and thermal stability, which limit their applications. Here, the mechanisms leading to the deterioration of Ag nanostructures are clarified. It is first shown that oxygen alone cannot oxidize Ag nanostru...
