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...
15 صفحه اولMechanism of nitrate reduction by Desulfovibrio desulfuricans nitrate reductase--a theoretical investigation.
The oxidative half-reaction of oxygen atom transfer from nitrate to an Mo(IV) complex has been investigated at various levels of theory. Two models have been used to simulate the enzyme active site. In the second, more advanced model, additional amino acid residues capable of significantly affecting the catalytic efficiency of the enzyme were included. B3LYP/6-31+G*, ONIOM, and orbital-free emb...
متن کاملNitrate and Nitrite: Sources, Impact on Human Health and Reduction of Nitrate Accumulation in Agricultural Products Using Bio-fertilizers
Nitrate with the chemical formula NO3- is one of the forms of nitrogen in the environment that plays an important role in the nitrogen cycle. Vegetables, water and meat are important sources of nitrate. Nitrate is made in the body through the arginine-NO pathway and enters the body through various sources. Oral nitrate is converted to nitrite (NO2-) by bacteria when it enters the mouth, and nit...
متن کاملTITANIUM ALUMINIDES SYNTHESIS BY ALUMINO-CALCIOTHERMIC REDUCTION OF TiO2
Abstract: Production of titanium aluminides in TiO2-Al-Ca system has been investigated. For this purpose, different compositions of raw materials were studied in a special reaction vessel. In a special case, the non-completed reaction of TiO2 with Al and Ca resulted in the production of granulates of titanium aluminides especially Ti3Al and other Ti – Al phases as the metallic product and C...
متن کاملEffect of molybdenum and tungsten on the reduction of nitrate in nitrate reductase, a DFT study
The molybdenum and tungsten active site model complexes, derived from the protein X-ray crystal structure of the first W-containing nitrate reductase isolated from Pyrobaculum aerophilum, were computed for nitrate reduction at the COSMO-B3LYP/SDDp//B3LYP/Lanl2DZ(p) energy level of density functional theory. The molybdenum containing active site model complex (Mo-Nar) has the largest activation ...
