Two methods for measuring plasma alkaline phosphatase activity are compared: one makes use of phenyl phosphate, carbonate-bicarbonate buffer, and continuous-flow methodology; the other of p-nitrophenyl phosphate, diethanolamine buffer, and reaction-rate analysis. Results by the methods correlate well (r = 0.98) over a wide range of values (up to 10-fold the upper limit of normal). A factor can ...

Acid Orange 7 (AO7) is one of the most common azo dyes; however, its strong bond makes them difficult to biologically degrade. We sought degrade AO7 dye using CeO2 as a promising alternative photocatalyst. powders were synthesized with monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA) precipitant by solvothermal process combined calcination in air. Compared oxygen storage ...

The limited performance of pure glassy and rubbery polymeric membranes for natural gas purification are due to their intrinsic properties. Optimizing properties by blending both polymers expected address the shortage. foremost objective this research is synthesis enhance polymer blend (EPBM) using polysulfone (PSU) polyvinyl acetate (PVAc) with addition amine carbon dioxide (CO2) removal from m...

The Effect of Diethanolamine on Hepatic and Renal Phospholipid Metabolism in the Rat. BARBEE, S. J., AND HARTUNG, R. (1979). Toxicol. Appl. Pharmacol. 47,421430. DEA inhibited the in vitro synthesis of both phosphatidyl choline and phosphatidyl ethanolamine in liver tissue. In each caSe the K, was approximately 3 mu DEA. DEA inhibited the formation of phosphatidyl choline competitively, and pro...

Abstract The average burial depth of carbonate reservoirs in Shunbei area exceeds 7300 meters, and the bottom hole temperature is as high 160°C. commonly used cross-linked acid system cannot meet needs fracturing. Therefore, this article uses AM, AMPS, acrylamide (AM) modified monomers, acrylic (AA) monomers to synthesize thickener SBCH-1, organic zirconium crosslinking agent SBJL1 was synthesi...

Although it is known that most growth inhibitors affect young plants more severely than older ones, and random observations have been made of this effect of maleic hydrazide (MH), there has been no systematic investigation of the effect of MH on plants of different ages. Since information of this type has both a practical and theoretical value, it appeared to be worth while to investigate the p...

Context. During the late 1990s, insecticide resistance had rendered a number of treatment products ineffective; some companies saw this as an opportunity to develop alternative types of treatment. We investigated the possibility that a surfactant-based lotion containing 10% cocamide diethanolamine (cocamide DEA) was effective to eliminate head louse infestation. Settings and Design. Initial in ...

In this work, 4-diethylamino-2-butanol (DEAB) as a new type of alkanolamine solvent is used for CO 2 capture in hollow fiber membrane contactor (HFMC). A model describing the gas and liquid reactions transport inside under wetting or non-wetting conditions was built. The countercurrent flow natural considered model. To investigate influence on decarburization efficiency, DEAB compared with othe...
