the underlying structure of language proficiency and the proficiency level
هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولpH-dependent mutarotation of 1-thioaldoses in water. Unexpected behavior of (2s)-D-aldopyranoses.
The pH-dependent mutarotation of 1-thioaldopyranoses in aqueous media has been investigated. Anomerization readily occurred at lower and neutral pH for all aldopyranoses studied, whereas mainly for (2S)-D-aldopyranoses at higher pH. 1-Thio-D-mannopyranose and 1-thio-D-altropyranose showed very strong pH dependence where the anomeric equilibrium ratios changed dramatically from a preference for ...
متن کاملThe hydrolysis of S-D-lactoylglutathione.
S-o-Lactoylglutathione is a thioester derivative. It is the physiological intermediate of the glyoxalase system and is present in the cytosol of cells and cellular organelles [l]. Exogenous S-o-lactoylglutathione. added to the extracellular medium of human leukaemia 60 cells in culture induces growth arrest and toxicity; the IC,, = 82 wM. There is no similar toxicity in corresponding differenti...

متن کاملThe synthesis and enzymatic hydrolysis of poly-D-lysine.
In studies of the inhibition in viva of animal viruses by poly-n-lysine, Rubini et al. (1) and Green et al. (2-4) obtained data which suggested that poly-L-lysine is hydrolyzed by the proteolytic enzymes of the allantoic fluid, and that this enzymatic hydrolysis may limit its biological activity. The enzymatic hydrolysis of poly-n-lysine was reported by Katchalski (5) and by Waley and Watson (6...
