The kinetics of mild steel corrosion in 20:0, 19:1, 18:2 and 15:5 (v/v%) aqueous mixture of acetic and formic acids has been investigated by weight loss and potentiostatic polarization techniques. The effects of composition of electrolyte and temperature on the corrosion rate of mild steel have been evaluated. The corrosion rate of mild steel increased linearly with temperature as well as amoun...

HoDGE[1] reported the determination of lipids in human gingiva. FISHER et al.[2] investigated into the cholesterol contents in bovine and human gingiva. STERN et al.[3] observed the incorporation of sodium acetate-1-14C into cholesterol, palmitic acid and oleic acid in human gingiva. OTAKE et al.[4] also reported the incorporationof sodium acetate-1-14C into the lipid fractions in guinea pig gi...

      Calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. Compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. In this study, various formulations of calcium acetate tablets were prepared and their disint...

Four kinds of modified starches that are expected to improve the quality crystal dumpling skins were selected, namely Potato acetate starch, hydroxypropyl Octenyl succinate starch sodium, Acetate cassava starch. Through determination physical indicators above four starches, and then explore feasibility applying them their quality. Studies have found light transmittance is higher than original m...

The presence of acetate exceeding 5 g/L is a major concern during E. coli fermentation due to its inhibitory effect on cell growth, thereby limiting high-density cell culture and recombinant protein production. Hence, engineered E. coli strains with enhanced acetate tolerance would be valuable for these bioprocesses. In this work, the acetate tolerance of E. coli was much improved by rewiring i...

Culture forms of Trypanosoma brucei S42 were maintained in defined media by serial subculturing (Cross & Manning, 1973; Klein et al., 1975). Under these conditions considerable quantities of L-threonine were metabolized and equimolar concentrations of glycine and acetate were excreted. Glycine was identified by using an amino acid analyser and acetate was characterized as the p-bromophenacyl de...

The article considers the classification of organoarsenic compounds and types their production; application computer simulation in chemical-technological processes. reaction for obtaining sodium 2-oxido(phenyl)arsoryl acetate was simulated, kinetic curves were obtained analyzed; parameters are set to increase yield product

Ethanol steam reforming (ESR) was investigated on unpromoted and several sodium promoted Pt/ZrO2 catalysts. From DRIFTS experiments, the following steps during ESR were inferred: dissociation of ethanol to produce ethoxy species; oxidative dehydrogenation species acetate; acetate decomposition. Acetate decomposition depends catalyst formulation. Decarboxylation is most favored route at high loa...

In vivo localized and fully adiabatic homonuclear and heteronuclear polarization transfer experiments were designed and performed in the rat brain at 9.4 T after infusion of hyperpolarized sodium [1,2-(13)C(2)] and sodium [1-(13)C] acetate. The method presented herein leads to highly enhanced in vivo detection of short-T(1) (13)C as well as attached protons. This indirect detection scheme allow...
