In the present investigation the influence of the ambient temperature on biogas production was determined. This relationship is necessary to establish, depending on the ambient temperature of each locality in which time and just installed a biodigester charged will be full of biogas.This tubular biodigesters PVC geomembrane, 8 and 12 m3 total volume (1.27 m diameter and 6.7 to 10 m in length) were used, with 6 and 9 m3 working volume, respectively, occupied by the mixture of cattle manure: water in the ratio 1: 5. Biodigesters were installed at seven locations of Amazonas, San Martín and La Libertad regions - Peru; different temperature and height above sea level. At each site the hydraulic retention time (HRT), in days, required for the biodigester bell ball and extra storage are full of biogas was determined.Based on the results obtained, the height above sea level and the volume...

Se utilizó los residuos organ1cos domésticos y ganaderos contaminantes para rroducir biogás. Los biodigestores fueron botellas de plástico de 1750 mL. El biogás producido se colectó por desplazarn iento de agua, en botellas calibradas de plástico de 260 m L. Se aplicó el diseño estadístico de Box-Benhken con tres variables independientes: relación estiércol:agua ( 1: 1, 1 :2, 1 :3), agua de desagüe(% v/v de agua de desagüe con respecto al volumen del biodigestor: 2, 4. 6) y cáscara ele papa(% p/v de cáscara de papa con respecto al volumen ele estiércol: 3, 6, 9). Se real izó 15 experimentos por triplicado durante 45 días. El mayor volumen de biogás producido fue de 195 mL, empleando 583 mL de estiércol (estiércol:agua de l :2), 35 mL de agua de desagüe (2% v/v) y 79 g de cóscara de papa (9% p/v). El tratamiento de los resultados con Statgraphics 5.0, permitió pre...

The solar radiation that reaches the earth is the fundamental source of renewable energy in nature, therefore, knowing the local solar radiation is essential for many applications. The objective of this study was to model the behavior of daily solar radiation in the city of Bagua, which allows us to plan and design strategies oriented towards the use of the primary source of renewable energy. For this, the Fernández-Zayas model has been used, which considers the parameters of the monthly  average of the maximum global solar radiation and the length of the solar day. The methodology is of the analytical type and consisted of three phases: The first, data collection and filtering of the meteorological station of the Toribio Rodríguez de Mendoza National University of Amazonas that is located in the study area; in the second, the model was implemented using the MATLAB / GUI interface, ob...
