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 اولRe-endothelialization of punctured ePTFE graft: an in vitro study under pulsed perfusion conditions.
BACKGROUND When used as arteriovenous (AV) shunts for haemodialysis, small diameter expanded polytetrafluoroethylene (ePTFE) grafts have a high failure rate in vivo. Attempts to improve graft patency are various, and focus on either improvement of implantation techniques or graft tissue engineering. The tissue engineering approach attempts to reproduce in grafts the properties of pristine vascu...
متن کاملLong-term survival of autologous adrenal medulla grafts in the great omentum of the rat.
The omentum, a rich source for trophic and angiogenic factors, was explored as a potential intermediate transplant site to facilitate long-term survival of chromaffin tissue. Autologous rat adrenal medullas were grafted into omental pockets. All grafts became densely vascularized. The grafted chromaffin tissue exhibited strong immunoreactivities for tyrosine hydroxylase, synaptophysin and chrom...
