the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...
چکیده diphyllidea van beneden in carus, 1863 راسته ای است از رده eucestoda که گونه های آن همگی تنها در دریاها زیست کرده و از گونه های مختلف سفره ماهی و یک خانواده از کوسه ماهیان به عنوان میزبان نهایی استفاده می کنند. در این مطالعه گونه ای جدید از جنس coronocestus caira, marques, jensen, kuchta and ivanov, 2013 متعلق به راسته diphyllidea از یک گونه کوسه ماهی به نام iago omanensis (norman) از د...
Vaccinia DNA topoisomerase IB (TopIB) relaxes supercoils by forming and resealing a covalent DNA-(3'-phosphotyrosyl)-enzyme intermediate. Here we gained new insights to the TopIB mechanism through "chemical mutagenesis." Meta-substituted analogs of Tyr(274) were introduced by in vitro translation in the presence of a chemically misacylated tRNA. We report that a meta-OH reduced the rate of DNA ...
Take home message Aim for a systolic blood pressure lower than the current recommended goal of 140 mm Hg. Optimum systolic blood pressure should be targeted to 120–130 mm Hg, especially in nondiabetic hypertensive patients with significant risk factors. Advantages of aggressive treatment to levels <120 mm Hg are still unclear. Lifestyle modifications rather than initiation of antihypertensive d...
this work is presented in five parts. in the first part preparation of the starting complex [pt(c^n)cl(dmso)], 1, in which c^n = n(1),c(2?)-chelated, deprotonated 2-phenylpyridine, and dmso = dimethylsulfoxide, and its reaction with 1 equiv of the biphosphine ligands bis(diphenylphosphino)amine, dppa, or bis(diphenylphosphino)methane, dppm, to give the complex [pt(c^n)cl(dppa)], 2, or [pt(c^n)c...
In the presence of NaY faujasite, dimethyl carbonate (MeOCO(2)Me, DMC) is a highly chemoselective methylating agent of functionalized anilines such as aminophenols (1), aminobenzyl alcohols (2), aminobenzoic acids (3), and aminobenzamides (4). The reaction proceeds with the exclusive formation of N-methylanilines without any concurrent O-methylation or N-/O-methoxy carbonylation side processes....
Monitoring of nucleus geometry and growth into dual types periodically ring-banded morphology in poly(nonamethylene terephthalate) (PNT), respectively, Type-1 Type-2, are done with detailed analyses using polarized-light optical microscopy (POM) in-situ CCD recording; the periodic assembly morphologies characterized atomic-force (AFM) scanning electron (SEM). Different annealing treatments (Tma...
