formaldehyde from shaped cellulose acetayte articles containing methylolated melamine or guanamine polymers is reduced by adding to the solutions from which the cellulose acetate article is regenerated, from 1 to 20% by weight based on the weight of the methylolated polymer of a cyclic urea ...
method for concentration of a solution of urea.in the area of synthesis (1).synthesis of urea solution containing carbamate is formed from carbon dioxide and excess ammonia in the first step of decomposition (2).a portion of the carbamate is decomposee; in the second stage of decomposition (...
A total of 100–400 μL urine was transferred from the supernatant into a 5-mm MR tube (VWR International, West Chester, PA, USA) and mixed with 100 μL 0.75 M phosphate buffer solution containing 0.5% TSP prepared in D2O. All MR spectra were recorded at 298 K on a Bruker Avance ...
0.2 g/kg body weight/day, administered in drinking water for 6 weeks. Changes in small intestinal morphology, including histomorphometric parameters of enteric plexuses, immunolocalization of claudin 3, MarvelD3, occludin and zonula ocludens 1 in the intestinal mucosa, and selected hormones, were ...
