MODELIZACIÓN DE LA CALIDAD DEL SUELO ASOCIADA A PLAGUICIDAS COMO UNA MODIFICACIÓN DEL MÉTODO DEL INSTITUTO BATELLE – COLOMBUS

The study dealed on the design and the application of a mathematical model for the determination of the soil quality, associated to pesticides of more common use. The pattern consisted on an extensive modification of the Index of Water Quality developed by Institute Batelle Colombus, USA, to be applied to the soil (Index of Soil Quality Associated to Pesticides, ISQAP), in relation with pesticides. A wide group of values of concentrations of these compounds was used and, once proven the adjustment of the pattern to the same ones, it was proceeded to apply it using concentrations obtained data for agricultural soils of the Caluma low part, Bolivar county, Ecuador. The results demonstrated an Index average value of 42%, indicative of an Environmental Quality Level around 0.61; this is, "bad"; being recommended the amplification of the study to other areas of the studied microcuenca, as well as to others in those that is suspected of an indiscriminate pesticides employment, as well as the socialization of this work among the territory farmers population, propitiating their motivation in the good use of these compounds

Características probióticas de los lactobacillus: Una revisión

Los Lactobacillus constituyen una alternativa para mejorar el rendimiento y la salud en la producción animal; estos son una de las pocas especies endógenas que se encuentran en el tracto gastrointestinal de los vertebrados, incluidos los humanos, ratas, cerdos y pollos. Por lo tanto, el presente trabajo tuvo como objetivo principal el realizar una aproximación conceptual de varios autores acerca de las características probióticas de los Lactobacillus. Para ello, se hizo necesario realizar una profusa búsqueda, selección y procesamiento de las más prominentes fuentes bibliográficas, que tratan sobre este tema. El estudio se llevó acabo de 27 citas en idioma inglés, portugués y español; obteniéndose entre los principales resultados una clara conceptualización sobre características y utilización digestiva. A modo de conclusión la palatabilidad, normal transito gastrointestinal y utilización digestiva estas características son fundamentales para que el preparado microbiano a través de Lactobacillus puedan aportar para el mejoramiento de la salud del hospedador.
