La presente indagación tiene como fin establecer el grado de influencia de los eslabonamientos productivos y los sistemas productivos en el crecimiento económico productivo en el distrito de Curahuasi, provincia de Abancay en la región Apurímac en el periodo 2010-2015. El método seguido considera investigación de tipo aplicada, de ruta cuantitativa, nivel de investigación explicativo. La muestra ha sido de 22 actores territoriales entre empresarios, asociaciones y productores individuales. Se ha utilizado las técnicas de la recopilación documental y encuesta. Las conclusiones evidencian que las características del desarrollo económico productivo en el distrito de Curahuasi, evidencian que el sector agricultura, ganadería, caza y silvicultura representa el 30% del PBI; la población económicamente activa figura el 57,6% de los habitantes en época requerida para trabajar, det...

The objective of the research was to establish the degree of influence of the productive linkages and productive systems in the productive economic growth of the Curahuasi district, Abancay province - Apurímac region - period 2010-2015. Work was done with 22 territorial actors between associations and individual producers. The technique of documentary collection and survey was used. The results showed that the agriculture, livestock, hunting and forestry sector represents 30% of GDP; the gross domestic product increased to 37.1%; 81.6% are individual farmers, 90.9% are dedicated to the economic activity of the agricultural sector, the productive linkages, show 81.8% of the suppliers are from Curahuasi, 54.5% of services are located in Abancay. In production systems, 63.6% of sales occur in the local market, 54.5% are direct sales, and 72.7% use own brands. 72.8% consider that the locati...

La investigación tuvo como objetivo general, Determinar en qué medida incide la práctica evaluativa en el desempeño docente de la Facultad de Ingeniería de una Universidad Pública de Perú 2023. El tipo de investigación fue básica, enfoque cuantitativo, diseño no experimental correlacional causal de corte transeccional; la muestra estuvo conformada por 50 docentes de la Facultad de Ingeniería de una Universidad Pública; se han usado dos cuestionarios válidos a juicio de expertos y confiables, para procesar los resultados se usó el programa estadístico SPSS V26. Entre los resultados se encontró que para el 58,0% (29 docentes) las practicas evaluativas se halla en un nivel bueno; y para el 64,0% (32 docentes) el desempeño de desempeño docente alcanza un nivel Alto. Se concluyó que las practicas evaluativas influye significativamente en 73,2% en el desempeño docente; debi...

This research develops a mathematical model, a variant of the Economic Order Quantity (CEP) model based on historical demand information for products with a seasonal trend. The purpose is to calculate parameters of time and size of orders, so that these forecasts reduce costs and satisfy the estimated demand without entailing unnecessary expenses. The proposed model initially designs orders based on the forecast of future demand based on historical demand information with a seasonal trend (smoothed using the method of seasonal multipliers), then the forecast periods are grouped favorably (based on demand peaks), establishes logistical constants and analyzes the requirements in each group using restrictions that allow the volume of orders to be evaluated iteratively; Four analysis tests were carried out in different scenarios, redefining the logic of the restrictions. The results presente...

The aim of this work was extract, characterize and evaluate the antibacterial activity of the essential oil of Senecio graveolens Wedd (Wiskataya) against Escherichia coli and Staphylococcus aureus ATCC 29923. The leaves and stems of S. graveolens were collected in the district of Puquio 3800 m.s.n.m., Lucanas province, and department of Ayacucho. The essential oil was obtained by steam water destilation dried leaves and stems with yield 1.26% (w/w) to which physical testing were performed. The chemical composition was evaluated by gas chromatography with mass detector (GC-MS). Antibacterial activity of S. graveolens oil was tested by agar diffusion method in wells against Gram positive strains such as S. aureus ATCC 29923 and Gram negative as E. coli. The density a 20 ºC was 0.8755 g/ml; the index refraction was 1.4726 and the rate rotation was 102° 85' and the solubility miscible in ...
