a comparative study of language learning strategies employmed by bilinguals and monolinguals with reference to attitudes and motivation
هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
15 صفحه اولTransparent polycrystalline cubic spinels protect and defend
T he first reported work on transparent polycrystalline ceramics goes back to the 1950s. For example, some of the literature on materials discussed in this article, magnesium aluminate spinel and aluminum oxynitride spinels, traces back to late 1950s and early 1960s.1–3 The advantages of these materials over current state-of-the-art materials include • Ease of manufacturing; • Superior mechanic...
متن کاملThermoelectric Properties of Selenides Spinels
Many compounds with the spinel structure type have been analyzed for their thermoelectric properties. Published data was used to augment experimental results presented here to select promising thermoelectric spinels. Compounds studied here include C~~,~Al~.5Cr2Se4, Cu05Coo.5Cr2Se4, C~o,~Ino,~Cr2Se~ and CuIr2Se4. Many exhibit low lattice thermal conductivity of about 20 mW/cmK, independent of te...
متن کاملSpinels from the Dawros Peridotite, Connemara, Ireland
TWO different spinels, analyses of which are given, occur in the layered ultramafic rocks at Dawros. Chrome spinel occurs both as gravity-stratified cumulates and as complex orbs, while an Al-rich spinel is both in rocks of the main Dawros magmatic sequence and in an association with an aluminous bronzite, which may originate by recrystallization. It is concluded that while the chrome spinel is...
متن کاملMagnetic Order in Li-Mn Spinels
Magnetic measurements were carried out on different samples of Lithium-Manganese spinel LiMn 20 4 , great care having been taken to avoid the presence of spurious magnetic phases, such as Mn 3 0 4 . Susceptibility data, showing deviations from paramagnetic behaviour at about 40 K, were analyzed in terms of local magnetic interactions, taking into account the structural and transport properties ...
