Keeping Nanoparticles Fully Functional: Long-Term Storage and Alteration of Magnetite

Keeping Nanoparticles Fully Functional: Long-Term Storage and Alteration of Magnetite

Magnetite is an iron oxide found in rocks. Its magnetic properties are used for paleoclimatic reconstructions. It can also be synthesized in the laboratory to exploit its magnetic properties for bio- and nanotechnological applications. However, although the magnetic properties depend on particle size in a well-understood manner, they also depend on the structure of the oxide, because magnetite ...

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...

Short-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...

the effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test

in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
