The fuel qualities of several biodiesels containing highly saturated, mono, and poly unsaturated fatty acids, as well their combustion exhaust emission characteristics, were studied. Six biodiesel samples divided into two groups based on acid composition, including group 1 (coconut, castor, jatropha) II (palm, karanja, waste cooking oil biodiesel). All fuels (in both groups) tested in a single-...

The study investigates the effect of aluminium oxide nanoparticles as an additive to Madhuca Indica (mahua) methyl ester blends on performance, emission analysis of a single-cylinder direct injection diesel engine operated at a constant speed at different operating conditions. The test fuels are indicated as B10A0.2, B10A0.4, B20A0.2, B20A0.4 and diesel respectively. The results indica...

The relaxant effect of the methyl ester of rosuvastatin was evaluated on aortic rings from male Wistar rats (250-300 g, 6 rats for each experimental group) with and without endothelium precontracted with 1.0 µM phenylephrine. The methyl ester presented a slightly greater potency than rosuvastatin in relaxing aortic rings, with log IC50 values of -6.88 and -6.07 M, respectively. Unlike rosuvasta...

A partially purified preparation of an alpha-amino acid ester hydrolase was obtained from Acetobacter turbidans A.T.C.C. 9325, which catalyses synthesis of 7-(d-alpha-amino-alpha-phenylacetamido)-3-cephem-3-methyl-4- carboxylic acid (cephalexin) from methyl d-alpha-aminophenylacetate and 7-amino-3-deacetoxycephalosporanic acid. The enzyme preparation catalysed both cephalosprin synthesis from 7...

Energy is vital to the profitable growth of every nation and stimulate new research. Only natural resources can meet growing energy demand in recent years, biodiesel has become very interested as well environmental advantages that it be combined with mineral diesel fuel any quantity. The research focuses on study replacement a safflower methyl ester. engine tests shall performed using ester DI ...

THE TITLE COMPOUND [SYSTEMATIC NAME: (methoxy-carbonyl-meth-yl)ammonium chloride], crystallizes as a salt, C(3)H(8)NO(2) (+)·Cl(-), with the charged species inter-acting mutually via strong and highly directional N(+)-H⋯Cl(-) hydrogen bonds which lead to the formation of a supra-molecular tape running parallel to the c axis. Tapes close pack in the solid state mediated by multipoint recognition...

There is considerable experimental evidence in support of the view that, in solution, the state of molecular dispersion of insulin is dependent on the net charge of the protein (10, 6, 8). In these investigations, alterations of the net positive charge were obtained by varying the pH of the solutions, with due consideration of the effect of the specific binding affinity of the protein for anion...
