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 اولCrystal and Molecular Structure of 1,2,4-Triazolium Chloride and its Salt with Antimony Trichloride - Bis(1,2,4-triazolium) pentachloroantimonate(III)-1,2,4-triazolium Chloride
The structures of 1,2,4-triazolium chloride (C2H4N3)Cl and its derivative with antimony trichloride (C2H4N3)2[SbCl5] ÿ (C2H4N3)Cl containing unsubstituted 1,2,4-triazolium cations were determined. (C2H4N3)Cl crystallizes in the monoclinic system, space group P21/n with the unit cell dimensions at 86 K: a = 9.425(2), b = 8.557(2), c = 11.158(2) Å, þ = 95.87(3); V = 895.2(3) Å3,Z= 8,dc = 1.566,dm...
متن کاملSynthesis and crystal structure of Zinc (II) Complex [Zn(25-MBTSC)2I2]
Zinc (II) complex, [Zn(25-MBTSC)2I2] (1), where (25-MBTSC = (E)-2-(2,5-dimethoxybenzaldehyde) thiosemicarbazone, has been synthesized from the reaction of ZnI2 with 25-MBTSC in methanol as solvent at 25 ºC. It was characterized by elemental analysis (CHN) and is confirmed by single-crystal X-ray diffraction analysis. The complex 1 crystallizes in a triclinic system, with space group P-ī, having...
متن کاملCrystal structure of [bis[N-(2-hydroxyethylamino)ethylsalicylaldiminato]-iron(III)] chloride.
tetraethylenepentaamine and N-2-hydroxyethyl-ethylenediamine give condensation reactions with salicylaldehyde and form polydentade ligands with a linear structure. These polydentade ligands are suitable for several types of coordination geometry.1,2 The complexes formed by these ligands and transition metals have been reported in the literature concerned with coordination compounds for the last...
