Reduction of Substituted Resorcinols. I

the effect of consciousness raising (c-r) on the reduction of translational errors: a case study

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...

NITROIMIDAZOLES XI1 [I]: SYNTHESES OF TRISUBSTITUTED PYRAZOLES AND SUBSTITUTED (1 -METHYL-5-NITRO-2- IMIDAZOLYL) PYRIMIDINONES

The reaction of P-diketones 1 with phenyl hydrazine afforded 5-aryl-3-(1- methyl-5-nitro-2-imidazoly1)-1-phenylpyrazole (2) and 3-aryl-5-(1-methyl-5- nitro-2-imidazoly1) -1-phenylpyrazole (3). The reaction of diketones (1) with urea in the presence of p-toluenesulfonic acid gave 4-(or 6-)aryl-6-(or 4-)(1-methyl- 5-nitro-2-imidazolyl)-1-(lH)pyrimidones (4). The structures of all compounds w...

Electrochemistry of substituted salen complexes of nickel(II): Nickel(I)-catalyzed reduction of alkyl and acetylenic halides

Dimethyl-, diethyl-, and diphenyl-substituted analogues of nickel(II) salen have been synthesized, and the cyclic voltammetric behavior of each compound at a glassy carbon electrode in dimethylformamide (DMF) containing tetra-n-butylammonium tetrafluoroborate (TBABF4) has been compared with that of nickel(II) salen itself. Differences in the cathodic peak potentials for these species have been ...

Dissimilatory bacterial reduction of Al-substituted goethite in subsurface sediments

The microbiologic reduction of a 0.2 to 2.0 mm size fraction of an Atlantic coastal plain sediment (Eatontown) was investigated using a dissimilatory Fe(III)-reducing bacterium (Shewanella putrefaciens, strain CN32) to evaluate mineralogic controls on the rate and extent of Fe(III) reduction and the resulting distribution of biogenic Fe(II). Mössbauer spectroscopy and X-ray diffraction (XRD) we...
