La tesis se propuso por objetivo llegar a determinar la medida en que la aplicación del estudio de métodos puede mejorar la productividad en el desmontaje de aros camiones en Minera Las Bambas, 2018. Con tal fin se efectuó un estudio de enfoque cuantitativo, contando con un diseño de nivel cuasi experimental. La población del estudio se encontró compuesta por la información recogida de forma cuantitativa en el área de desmontaje de aros, recolectándose con frecuencia diaria, de tal manera que la población fueron los períodos de tiempo de 12 semanas. La muestra, por la temporalidad en la que se recogieron los datos, se constituyó de la población, es decir, 12 semanas. La conclusión principal señaló que la aplicación estudio de métodos mejora significativamente la productividad en el desmontaje de aros camiones en Minera Las Bambas, 2018. En esa línea, la media de la pro...

The present work had as objective to study the increment of the leaf area of Asparagus Officinalis L., for they were used it asparagus crown with 5 yolks, to those that were applied by aspersion, different concentrations of the hormones of gibberellic acid and 6-bencilaminopurina which were applied at the 25, 60, 110 and 160 days respectively. It was found that in the different rehearsed treatments one doesn't observe differential significant in the increment of the number of plants, plant height, number of yolks and dry weight of foliage. However it was observed that the combined application of the phytohormonas in the range of 0.110 at 0.230 m of gibberllic acid and 0.037 to 0.075 m of 6-Bencilaminopurin a bigger number of yolk is achieved (13%), sprout (7%), plant height (11.3%) and dry weight (7.3%) in the treated plants. Concluded to continue making studies of sinergism of these two...

The present research was carried out with the purpose to evaluate the different concentrations of rectified ethanol in the production of “bioaroma” ethyl acetate and single cell protein from Candida utilis var.major for it a stirred – tank reactor of 16 cm of height with turbine Rushton was built. The preparation of the inoculum was carried out starting from Candida utilis var. major C.E.C.T. 1430. The broth of culture was formulated starting from rectified ethanol dilutions from 10 to 35 g/L each 5 units. The bioprocess was carried out at 25ºC to pH 4.5 – 5.5 and during a time of 60 hours. It was found that the biomass productivity increase progressively from 4.82 to 7.90 g/L and from 0.082 a 0.108 g/L-h) respectively. Such as increase the rectified ethanol concentration (g/L) the production and the yield was down. The yield acetate ethyl was top to concentrations of 15 g/L of ...
