-
(SPRINGER-VERLAG, 2001-10)The possibility of a total substitution of ega proteins in yellow cakes by vegetable proteins isolated from white lupine seeds was studied. The effects of several components on hardness, moisture content, volume, and shape ...
-
(1981)A subbituminous coal from La Union (Chile) has been treated with aqueous NaOH solutions. The quantity of coal solubilized and the elimination of ash was found to increase with increase in hydrolysis time, temperature and ...
-
(Elsevier Ltd, 2009)The simultaneous occurrences of electrochemical reactions responsible for corrosion of carbon steel in NaCl solutions have been analyzed on the basis of the mixed potential theory in order to determine the combined effect ...
-
(BioMed Central, 2016)Background: Maule Cohort (MAUCO), a Chilean cohort study, seeks to analyze the natural history of chronic diseases in the agricultural county of Molina (40,000 inhabitants) in the Maule Region, Chile. Molina's population ...
-
(1993)An investigation of the influence of the aggregate sizes on some elements of an oxisol is presented. Proton Induced X-ray Emission (PIXE) has been used to carry out this analysis. Aggregate sizes from <0.5 mm to 4.7 mm ...
-
(Instituto Antártico Chileno, 1993)La determinación de los niveles de contaminación atmosférica de un lugar, exige el conocimiento de las concentraciones naturales de especies en el aire. En la época actual es muy dificil encontrar áreas con atmósfera ...
-
(1995)Plant defense against pathogens involves mechanisms that include the expression of several genes, which could be located in any of the three compartments that contain genomes in plant cells: nuclei, mitochondria and ...
-
Subcellular remodeling of the T-tubule membrane system: The limits of myocardial recovery revealed? (Lippincott Williams and Wilkins, 2017)
-
(SOC MEDICA SANTIAGO, 2008-09)Background: Type I familial hyperaldosteronism is caused by the presence of a chimaeric gene CYP11B1/CYP11B2 which encodes an enzyme with aldosterone synthetase activity regulated by adernocorticotrophic hormone (ACTH). ...
-
(AOAC INTERNATIONAL, 2006-04)A rapid and simple continuous method for the extraction of nifedipine from tablets was developed by using pressurized hot water at 150 degrees C. This is the first time that subcritical water was applied to the extraction ...
-
(2006)Copper-embedded low-density polyethylene (LDPE) composites were fabricated using different copper concentrations in the polymer matrix. The copper particles were spherical with a mean particle size between 200 and 300 nm. ...
-
(Elsevier B.V., 2017)Tetra-tert-butyl-cis,cis-3,7-dihydroxybicyclo[3.3.0]octa-2,6-diene-2,4-exo-6,8-exo-tetracarboxylate (I) and tetra-tert-butyl-cis,cis-3,7-dimethoxybicyclo[3.3.0]octa-2,6-diene-2,4-exo-6,8-exo-tetracarboxylate (II) were ...
-
(ELECTROCHEMICAL SOC INC, 2009)The electrochemical reduction of 1-methyl-4-nitro-2-carboxyimidazole (RNO2COOH) in a nonaqueous medium produced two reduction signals, which were influenced by the dissociation of the compound. The first reduction signal ...
-
(Elsevier Science SA, 2018)Lercanidipine (LERCA) is a third generation antihypertensive drug belonging to the 1,4-dihydropyridine's family, which has been reported to induce photoallergic and/or phototoxic effects in patients with long term treatment. ...
-
(The American Society of Photobiology, 2014)The electronic nature of substituents attached to the 4-aryl moiety of 1,4-dihydropyridines strongly affects the photophysical and photochemical behavior of these family of compounds. The presence of an electron donor ...
-
(CHEMICAL SOC JAPAN, 2002-09)Hydroxyl and phenyl radical spin trapping rates by alpha-phenyl-N-t-butylnitrone (PBN, N-benzylidene-t-butylamine N-oxide) and its analogs were determined using a competitive trapping method. Hydroxyl radical was generated ...
-
(1994)AM1 full geometry optimization of seven substituted cyclic hydroxamic acids (Hx) was performed. A qualitative correlation between Elumo vs Hammett's σP was observed. The reactivity of these 7-substituted Hx with hard ...
