Introducción y objetivo: el modelo de Educación Física Calidad la UNESCO, se amplía fortalece a nivel mundial. Así, este trabajo busca analizar percepción profesionales en República Dominicana, sobre calidad su país. Metodología: estudio enfoque cuantitativo, correlacional, no experimental diseño transversal. La población estuvo constituida por activos Dominicana. muestra fue probabilística, tipo accidental, con 351 informantes, aplicándose Índice Global Calidad. Resultados: media general...
Abstract The efficiency of conversion the carbon‐energy source to product is primary importance in many fermentation processes. In order assess a process, one must know how close actual yield theoretical maximum. Theoretical yields are useful, therefore, as guides improving process. This knowledge particularly important today because cost raw materials rapidly rising. this study, biochemical pathway penicillin synthesis was used estimate from glucose, ammonia, and sulfate. These values...
Abstract Penicillin amidase, an enzyme which hydrolyzes benzylpenicillin to 6‐aminopenicillanic acid and phenylacetic acid, is produced by Bacillus megaterium ATCC 14945 as extracellular enzyme. We used this system a model examine the effects of nitrogen, sulfur, phosphorous limitation on production in continuous culture. For these studies, we developed minimal medium for B. contained histidine sole nitrogen source. Batch experiments showed that growth‐associated metabolite. Enzyme was shown...
A new technique is presented to detect and quantify birch (Betula pendula)‐pollen allergens directly on air‐sampling filters. It based the use specific antibodies, enzymatic reactions, measurement by chemiltiminescence or densitometry. The major pollen antigens are most important allergens. antibodies used recognb.e birch‐pollen which thus correspond Calibration was done with standardized extract of for skin prick testing. correlation coefficient logarithms luminescence amount birch‐poUen...
