-
(1986)The photochemistry of alkyl pyruvates of the type CH3COCOOCHR2 has been examined in solution using a combination of product studies and laser flash photolysis techniques. The results indicate that the main reaction path ...
-
(1986)Trazodone, a triazolopyridine derivative with antidepressant activity, is irreversibly oxidized in two steps in a large range of scan rates. The first peak shows a linear dependence on trazodone concentration. This behaviour ...
-
(1986)Solubilities and IR spectra of DIMBOA in alcoholic solvents showed that the carbonyl group of DIMBOA is hydrogen-bonded to the solvent. Activation parameters of DIMBOA in the same solvents suggested that the decomposition ...
-
(Real Academia de Farmacia, 1986)Se ha determinado mediante ensayos en aurícula aislada de cobayo los efectos sobre la fuerza de contracción y frecuencia cardíaca de Senecionina, alcaloide pirrolizidínico aislado de Senecio fistulosus Poepp ex Less. (Hualtata).

-
(Elsevier, 1987)The ability of the ligninolytic actinomycete Streptomyces viridosporus T7A to degrade selected lignin model compounds, both in the presence and in the absence of lignocellulose, was examined. Compounds studied included ...
-
(Chile, Instituto de Investigaciones Agropecuarias, 1987)A technique was studied and later implemented to determine the amount of polyphenoloxidase removable from soils. This enzymatic activity favors oxidation processes such as those of phenols. These are the foundations for ...
-
(Dustri-Verlag Dr. Karl Feistle, 1987)Dibekacin pharmacokinetics was studied in ten healthy volunteers and six patients with renal failure presenting Clcr<10ml.min-1 per 1.73m2 of body surface, given as a low intravenous bolus to the volunteers and as 30-minute ...
-
(Sociedad Chilena de Tecnología de Alimentos, 1987)Se analizan muestras de chocolates: con leche en barra, de fantasía en barra, en polvo amargo, en polvo dulce y coberturas de helados para determinar la calidad y cantidad de la materia grasa como también el valor calórico ...
-
(Royal Society of Chemistry, 1987)In piridine - formic acid buffer and tetramethylammonium chloride solution of pH 4.5 at a dropping mercury or a glassy carbon electrode, nitrofurazone, furazolidone and nitrofurantoin are reduced in a single six-electron ...
-
(Royal Society of Chemistry, 1987)In pyridine - formic acid buffer and tetramethylammonium chloride solution over the pH range 0-8.5, nitrofurazone, furazolidone and other nitrofuran derivatives are reduced in a six-electron process, giving rise to a well ...

-
(1987)Soil samples collected in 1982 and 1983 from locations near an industrial park consisting of a Mo ore processing plant and a car battery manufacturing industry were analyzed for total and extractable Mo and Pb. Grass samples ...
-
(1987)Alfalfa plants (Medicago sativa, L. cv. Aragón) inoculated with Rhizobium meliloti weregrown with a N-free-nutrient solution in controlled environmental chambers. After 5 weeks plants were placed under 2 irradiance regimes ...
-
(1987)A complete description of the rotational isomerism of monothioformic acid is presented. Ab initio results concerning the barrier heights and the energy difference between the stable isomers are in good agreement with the ...
-
(1987)The deactivation of a number of excited polycyclic aromatic hydrocarbons by copper(II), cobalt(II), nickle(II) and chromium(III) in ethanol-water (1:1 by volume) has been investigated. In spite of the fact that most of the ...
