5-aminosalicylic acid (5-asa) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-nsa) in acidic media. in this work, electrolytic reduction of 5-nsa in alkaline media is presented. reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the ph for isolation of product are investigated. the yiel...

in order to evaluate the effect of using zinc granulated phosphorous biofertilizer on yield and yield components of white bean (phaseolus vulgaris l.), a field experiment based on a randomized complete block design with three replications was performed. experimental treatment were included of using phosphate and triple super phosphorous chemical fertilizer at five levels (without using of chemi...

The objective of this study was to characterize breeds representing diverse biological types for postweaning growth and carcass composition traits in terminal crossbred cattle. Postweaning growth and carcass traits were analyzed on 464 steers and 439 heifers obtained by mating F(1) cows to Charolais and MARC III (1/4 Hereford, 1/4 Angus, 1/4 Pinzgauer, and 1/4 Red Poll) sires. The F(1) cows wer...

An improved and facile preparation of 3,7-dinitro-1,3,5,7-tetraazabicyclo [3,3,1] nonane(DPT) has been developed starting from urea. In the procedure DPT was synthesized viaN,N’-dinitrourea (DNU) as intermediate and various operating parameters such astemperature, pH and molar ratio of reagents have been optimized to give maximum yield ofthe desired product. The low cost method is concise, oper...

Many Asian countries are expected to undergo transformations in their economies and rapid urbanization over the next 25 years. The changes in tastes and lifestyles engendered by urban living are likely to have significant influences on food demand--influences perhaps as strong as the well-documented effects of household in comes and food prices. Changes in marketing systems and occupations, clo...

This study provides details of a novel continuous process to eliminate the pollution of yellow phosphorus tail gas, which can also produce high quality and low cost formic acid, with a particular focus on the high and variable viscosity of the system and the rationality of energy utilization. A compact acidification reactor was developed as the key equipment used in this novel process, based on...

Postweaning growth, feed efficiency, and carcass traits were analyzed on 1,422 animals obtained by mating F1 cows to F1 (Belgian Blue x British breeds) or Charolais sires. Cows were obtained from mating Hereford, Angus, and MARC IIIHereford, 1/4 Angus, 1/4 Pinzgauer, and 1/4 Red Poll) dams to Hereford or Angus (British breeds), Tuli, Boran, Brahman, or Belgian Blue sires. Breed groups were fed ...

BACKGROUND In recent years, constraint-based metabolic models have emerged as an important tool for metabolic engineering; a number of computational algorithms have been developed for identifying metabolic engineering strategies where the production of the desired chemical is coupled with the growth of the organism. A caveat of the existing algorithms is that they do not take the bioprocess int...
