El proyecto se enfoca en evaluar estrategias de enfriamiento de un módulo de baterías de iones de litio de tipo cilíndricas para la prevención del sobrecalentamiento. Para el efecto se realizarán distintas simulaciones numéricas mediante herramientas de dinámica de fluidos computacional (CFD, por sus siglas en inglés).

A partir del marco legal vigente que faculta la planificación en el País con diferenciación en los Territorios Ancestrales –TA-, el presente artículo muestra cómo vincular las herramientas de planificación en los gobiernos cantonales para la implementación de las políticas públicas.

La caficultura es una actividad importante en Ecuador ya que se practica en todas las regiones del país, bajo diferentes pisos altitudinales, tanto en monocultivos como en sistemas agroforestales. La principal característica del café ecuatoriano es sus exquisitos aroma y sabor, reconocidos a nivel internacional. Al ser una bebida de alto consumo, su comercialización constituye una fuente de ingresos importante para todos los actores que intervienen en los diferentes eslabones de su cadena de producción.

La contaminación acústica es un problema ambiental, que afecta a largo plazo los procesos auditivos de los seres humanos y las condiciones de vida. Este inconveniente se acentúa con fuerza principalmente en las grandes metrópolis, en donde las actividades productivas, comerciales e industriales, tienen una intensa dinámica; esto genera un entorno disfuncional y de precariedad del estándar de vida en la población.

International Journal of Health Science is a bimonthly periodical edited by Atena Editora, being an important vehicle for the dissemination of scientific works arising from relevant research in the health area.

Manuscripts are accepted in: Portuguese, Spanish and English. Articles submitted in Portuguese will be translated into English and published in that language. For articles submitted in Spanish and English, there will be no translation needed.

This work aims at obtaining a method to homogenize series of wind speed, in the meteorological stations of the National Meteorological and Hidrological Institute (INAMHI) in the Loja Province, Ecuador Republic. Homogenization tests applied include non-parametric and the Alexandersson test (SNHT). Multiple Regression Analysis is used to determine the problematic values from the absolute values of the Student residuals bigger than 3 and to calculate the their replacements. Results are shown for the January series.

In this work is presented an approach to the theoretical solar radiation in El Oro, Loja and Zamora Chinchipe provinces (Ecuador), from the Hottel’s Model, considering the daylight cloud amount and using atmospheric transmittance, solar zenith angle, altitude, and climate type. Resulting Global Solar Radiation amounts using altitudes of the Digital Terrain Model of the study area are shown for annual totals and for the months of January and August. Conclusions and recommendations are given.

Different theoretical models exist for obtaining an initial knowledge about the solar radiation values on a horizontal surface in a certain place. The present work is focused in obtaining the solar radiation values on a horizontal surface using Hottel model.

One of the objectives of the present work is the determination of areas in which it is possible the use of the Eolic energy. In the study area information is not enough, reason why it is necessary to use other sources of data. Digital Elevation Models (DEM) allow us to know areas where the winds can flow due to orographic factors. A DEM for the area of the project was processed and obtained, with nodes every 0,001◦ . Data of reanalysis of different elements performed by NASA were used.

An approach is presented to the solar radiation possible to obtain in the provinces El Oro, Loja and Zamora Chinchipe, South Region of Ecuador (RSE) using images of the Geostationary Satellite GOES-East, and the data of global radiation obtained in a net of five automatic stations located in the RSE from which a theoretical model was obtained, by means of multiple regression analysis among the bands RGB (Red, Green, Blue) of the Visible and Infrared images of the GOES and the instantaneous data of global radiation in the stations.
