abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
Single crystals of tris(2,3,4,6,7,8,9,10-octahydropyrimido[1,2- a ]azepin-1-ium) tri-μ 2 -iodido-bis[triiodidobismuth(III)], (C 9 H 17 N ) 3 [Bi I ], were prepared by solvothermal method, heating mixture BiI , KI, 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and ethanol at 443 K for six days. The asymmetric unit the title compound, which crystallizes in monoclinic space group P 1 / c contains one ]...
The topological features of the formation (Co40Fe40B20)15(LiNbO3)85 composite films deposited by ion-beam method on a metal electrode Cr/Cu/Cr has been investigated. presence dielectric layer between upper Cr and CoFe–LiNbO3 film with thickness dox ~ 15 nm established. difference in size granules near amorphous volume shown. A model (Co40Fe40B20)x(LiNbO3)100–x nanocomposite at initial stage gro...
A NASICON-type LiZr2(PO4)3 (LZP) and Li1.2Al0.2Zr1.8(PO4)3 (LAZP) anode materials are synthesized via a facile method, were characterized by variety of structural techniques, investigated the electrochemical performance for rechargeable battery applications. highly stable rhombohedral phase LAZP is noticed at room temperature, with discharge capacity 909 mAh.g−1, which 1.6 times higher than tha...
