In the present investigation it will benefit the rural population of the High Andean communities, that adopt biogas and biofertilizer as alternative energy and organic fertilizer, respectively; As they will have at their disposal an ecological fuel and organic fertilizer throughout the year, improving their quality of life.For this purpose, tubular biodigesters of PVC geomembrane of 8 and 12 m3 of total volume (1.27 m in diameter and 6.7 to 10 m in length) were used, with 6 and 9 m3 of working volume, respectively, occupied By the manure mixture of cattle: water in the proportion 1: 5. Biodigesters were installed in the Andean communities.Ancash. Peru. Based on the results obtained, at 38 days of loading the biodigester, the biogas produced reached a pressure of 10 cm of water throughout the system. For all this activity, it was required an operating time of the kitchen to biogas of two ...

Based on the need to make accurate decisions in the face of the COVID-19 pandemic in Peru, pandemic in Peru, specifically for the recovery of the tourism sector. For this purpose, a characterization of the behavior of the pandemic was carried out in the first three months of its development, based on the analysis of trends and the determination of the effective reproduction number (Rt) from statistical-mathematical methods. A variant of the SIR mathematical model was applied to forecast the possible evolution of the pandemic. This model was adjusted with the GlobalSearch optimization strategy of the MATLAB software. His solution used the MATLAB function ode23tb, which uses a combined Runge-Kutta algorithm with a trapezoidal rule algorithm. With the application of the Kaizen strategy as a means of continuous improvement, a set of actions were proposed that could be carried out today and t...

Medicine plants contribute to solver problems about topics in health as important sources of resources which benefit our countries and societies with state management politics in long term. The purpose of this investigation was to catalogue native medicine plant species in region Ancash, Perú, made from 2006 to 2007. Through botanical explorations, longitudinal and transversal transects covered 12 provinces belong to Callejón de Huaylas and Callejón de Conchucos highlands regions. Moreover, were carried out surveys to determinate the degree of exploitation of medicine plants, as well as receive reports with regards to common names, part of plant employed and traditional uses. All this information, organized in figures and graphics, allowed to conclude that in this region grown 132 plants species, distribute in 109 genus and 55 families and according to degree of exploitation, exist pl...

Debido a la baja productividad de los cultivos y la escasa asistencia técnica a los agricultores en los países en desarrollo, se agudiza la problemática por la falta de alimentos, provocando muertes por hambruna. Tal realidad, particularmente en el medio rural, plantea la necesidad de elevar la creatividad de la gente, de los profesionales del agro, de las instituciones y de los organismos del estado, aprovechando al mismo tiempo, las particularidades de cada territorio, país o región. Por otra parte, el uso de las energías renovables no es un hecho novedoso, fueron ellas las primeras utilizadas por el hombre; sin embargo, el descubrimiento de los combustibles fósiles las relegó por muchos años al olvido, a pesar de las más conocidas características negativas de éstos (extinguibles y fuertemente contaminantes). Hoy en día, el panorama ha cambiado y aunque es cierto que las e...

Una gestión ecoeficiente municipal considera a los residuos sólidos como un recurso y su aprovechamiento como una actividad rentable ecológica y económicamente. Significa un cambio radical en el enfoque del manejo de residuos que pasa de recolectarlos para la disposición final a segregarlos para su utilización como materia prima en diferentes procesos productivos limpios incluido la generación de energía. La mayoría de las ciudades latinoamericanas no recolecta la totalidad de los residuos sólidos generados, y sólo una fracción de los residuos recibe una disposición final adecuada, provocando contaminación ambiental y riesgos para la salud humana. El reciclaje representa una opción más deseable que la disposición masiva de residuos en basureros o rellenos sanitarios. Sin embargo, pocos programas oficiales de reciclaje existen en la región (Medina, 1999). El incremento d...

En la presente investigación beneficiará a la población rural de las comunidades altoandinas, que adopte el biogás y biofertilizante como energía alternativa y abono orgánico, respectivamente; pues tendrán a su disposición un combustible ecológico y abono orgánico a lo largo de todo el año, mejorando su calidad de vida.Para ello se emplearon biodigestores tubulares de geomembrana de PVC, de 8 y 12 m3 de volumen total (1,27 m de diámetro y 6,7 a 10 m de longitud), con 6 y 9 m3 de volumen de trabajo, respectivamente, ocupado por la mezcla estiércol de ganado vacuno: agua en la proporción 1:5. Se instaló biodigestores en las comunidades andinas.Ancash. Perú. En base a los resultados obtenidos, a los 38 días de cargado el biodigestor, el biogas producido alcanzó una presión de 10 cm de agua en todo el sistema. para toda estaactividad se requirió un tiempo de funcionamient...
