In this paper, systematically describes the technology developed in this laboratory for the analysis of skeletal muscle, taken as an expression of the cellular phase of the organism, which is a great tool for future research on the changes that would occur in the intracellular environment during various pathological processes, or in many other biological problems. In our particular case, and as part of the curriculum of renal failure, we want to establish if it means intracellular biochemical changes, as with the extracellular environment, or whether its composition is more or less independent of renal function.

La presente Tesis de investigación busca evaluar, analizar el estado situacional de uno de los modelos de equipos críticos de la Unidad Minera de Extracción de Cobre, con el objetivo de incrementar la disponibilidad mecánica y diseñar un Plan de Mantenimiento mediante la aplicación de la Metodología Basado en la Confiabilidad RCM. El primer paso en el análisis de confiabilidad es la recopilación de datos. Para realizar un análisis de mantenimiento efectivo, es esencial contar con datos precisos y completos. Los datos de mantenimiento presentados en este documento se refieren a tres Cargadores de Bajo Perfil R1600G (N°16,17 y 18). Estos datos se recopilaron durante un período de 12 meses (Enero-Diciembre del 2014) mediante el uso de formularios escritos a mano preparados por personal de mantenimiento, informes diarios y tarjetas de mantenimiento. Estas tarjetas de mantenimient...

The objective was to propose a sustainable water management model based on an evolutionary study for sustainable development in the Piura region. This work was carried out under the hypothetical deductive paradigm, of a basic substantive type with a cross-sectional correlational design. Two questionnaires were used: questionnaire 1, applied to a sample of 220 families, to obtain information on water consumption, and questionnaire 2, applied to a sample of 36 professionals in the exercise of public administration, these instruments were complemented with bibliographic cards. The chi-square test (X2), degrees of freedom = 32) was used with a significance level of 5% (α = 0.05) in order to demonstrate the hypotheses raised. Confronting the values obtained experimentally, the null hypothesis was rejected. The management model and the evolutionary study of water do contribute to the sustaina...

Goal. Demonstrate how the management of systemic environmental management contributes to the growth of sustainable development in small and medium-sized companies in the public and private sectors in the Piura region. Material and method. This work was carried out under the deductive hypothetical paradigm, of a basic substantive type and of transversal correlational design. The study was made up of 159 managers and administrators of the entities mentioned. The survey technique was applied through questionnaires that comprised the dimensions of 1) personal domain, 2) mental models, 3) continuous learning and shared vision, 4) systemic thinking. While the methodology was used, the Chi-Square analysis problem was established to establish the association levels based on the analysis of dichotomous contingency tables. Results. It was determined that it exists for the dimensions: personal doma...
