the aim of this study was to investigate the effect of steam treatment on nutritive value of date (phoenix dactylifera) leaves. date leaves were chopped and mixed with water or sulfuric acid solution to contain 50% moisture with or without 1% sulfuric acid. steam treatment of the date leaves was carried out using three levels of steam pressure (14, 17 and 20 bar), three reaction times (120, 180...

the our main goal of the present research is evaluating the performance of mno2 nanoparticles-agx zeolite composite as a novel adsorbent catalyst for the decontamination reactions of two most known sulfur mustard simulants; 2-chloroethyl phenyl sulfide (2-ceps), 2-chloroethyl ethyl sulfide (2-cees) at room temperature and monitoring by gas chromatography flame ionization detector (gc-fid) and g...

Ambient hydrolysis products in moist air and hydrolysis kinetics in argon with humidity of RH1.5% for polycrystalline LiH powders and sintered bulks were investigated by X-ray diffraction, Raman spectroscopy and gravimetry. The results showed that the hydrolysis products made up a layered structure of LiOH•H2O/LiOH/Li2O from surface of the sample to inside. In low humid argon atmosphere, the pr...

The effects of various substrates and alternative substrates on the hydrolytic activity of beef heart mitochondrial ATPase was examined. It was found that ATP and ADP are competitive inhibitors of ITP hydrolysis, and that in the presence of either ATP or ADP, ITP hydrolysis showed positive cooperativity. IDP inhibited ITP hydrolysis and caused positive cooperativity. When ITP was present during...

Nafamostat mesilate, an ester drug with extensive hydrolysis in vivo, exhibits species difference in the relative contribution for its hydrolysis in blood and tissues. For the rat, the main hydrolysis site may be blood and human may be tissue (mainly by liver). The paper gave in vivo evidence that human tissue may give more contribution for its hydrolysis. In the initial phase of drug administr...

Increased fisheries products have raised by-products that are discarded due to low economic value. In addition, marine still rich in protein and nutritional value biological activities give benefits human health. Meanwhile, there is pressure for sustainability practices industries reduce waste minimize the detrimental effect on environment. Thus, valorization through bioactive peptide mining cr...

BACKGROUND Explaining the reduction of hydrolysis rate during lignocellulose hydrolysis is a challenge for the understanding and modelling of the process. This article reports the changes of cellulose and lignin surface areas, porosity and the residual cellulase activity during the hydrolysis of autohydrolysed wheat straw and delignified wheat straw. The potential rate-constraining mechanisms a...

in the present study, tenorite (cuo) nanoparticles have been assayed for their catalytic properties. the decontamination reaction of chloro ethyl ethyl sulfide (cees) as an surrogate of sulfur mustard simulant have been accomplished on the surface of cuo nps with different weight ratios at ambient temperature and monitored by gas chromatography equipped with flame ionization detector (gc-fid) a...
