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...

MODELING OF HYDRATION KINETICS AND SHRINKAGE OF PORTLAND CEMENT PASTE
متن کاملDetermining the water - cement ratio , cement content , water content and degree 1 of hydration of hardened cement paste : Method development and validation on 2 paste samples
7 We propose a new method to estimate the initial cement content, water content and free water/cement ratio (w/c) 8 of hardened cement-based materials made with Portland cements that have unknown mixture proportions and 9 degree of hydration. This method first quantifies the composition of the hardened cement paste, i.e. the 10 volumetric fractions of capillary pores, hydration products and unr...
متن کاملAge-Related Changes in Doxorubicin-Induced Oxidative Damage: Protective and Pretreatment Effects of Short-Term Aerobic Exercise
ABSTRACT Background and Objective: Doxorubicin (DOX) is an effective anticancer drug. It has been shown that a short-term exercise performed prior to DOX-treatment has no effect on cardiotoxicity in young rats. In the present study, old and young rats were evaluated to determine the protective effects of pre-treatment with short-term exercise on D...
متن کاملEffect of Fine-Ground Ceramic Admixture on Early Age Properties of Cement Paste
Properties of cement pastes with fine-ground ceramics used as an alternative binder replacing Portland cement up to 20% of its mass are investigated. At first, the particle size distribution of cement and fine-ground ceramics is measured using laser analyser. Then, the material properties are studied in the early hardening period up to 28 days. The hydration process of studied materials is moni...
