conclusions application of zinc oxide as the photocatalyst can be effective in the removal process. background one of the important achievements of the past decade was the rapid growth of industries and accordingly production of various chemical compounds. objectives this study presents a combined system of photocatalytic oxidation and absorption solution to remove nitrogen oxides from polluted...

this study was conducted to determine in vitro crude protein degradation (ivdp) parameters and effective crude protein degradability (epd) of various feeds using the modified in vitro gas production (gp) technique. feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. rumen fluid was collected before the morning feeding from four rumen fistulated lam...

Glutamine has been suggested as an immediate source of nitrogen for the synthesis of essential nitrogenous components of protoplasm (l-3). Utilizing anterior pituitary growth hormone preparations for the production of nitrogen storage in dogs, we were unable to obtain any evidence that glutamine functions as an interim storage form of amino nitrogen (4). Changes produced in plasma glutamine and...

An in vitro study was conducted to determine the effect of nitrate-nitrogen used as a sole dietary nitrogen source on ruminal fermentation characteristics and microbial nitrogen (MN) synthesis. Three treatment diets were formulated with different nitrogen sources to contain 13% CP and termed i) nitrate-N diet (NND), ii) urea-N diet (UND), used as negative control, and iii) tryptone-N diet (TND)...

Four slow releasing non-protein nitrogen (NPN) sources viz. urea-straw (US), urea-starch (UST), biuret-straw (BS) and biuret-starch (BST) were compared with cotton seed meal (CSM) as control nitrogen source. In all experiments, 2% nitrogen level on DM basis in contents of each fermentation flask were maintained through replacing 30, 50 and 70% of CSM by respective NPN source. Four in vitro expe...
