    Artificial neural network modeling of phenol adsorption onto barley husks activated carbon in an airlift reactor por Loredo Cancino, Margarita

    Publicado 2013
    “…Purpose and method of the study: The production of activated carbon from barley husks (BH) by chemical activation with zinc chloride was optimized by using a 23 factorial design with replicates at the central point, followed by a central composite design with two responses (the yield and iodine number) and three factors (the activation temperature, activation time, and impregnation ratio). …”

    Polimorfismo de los genes que codifican para las proteínas VP4, VP7 y NSP4 de rotavirus y su asociación con la severidad de la diarrea por González Ochoa, Guadalupe

    Publicado 2006
    “…Abstract Of the viruses that cause gastroenteritis, rotavirus is the main causal agent of severe diarrhea; it causes the fence death 440,000 children per year at world-wide level. Some researchers point to proteins VP4, VP7 and NSP4 like pathogenicity factors; VP4 and VP7 are related with the penetration viral into epithelial cells and the synthesis of neutralization antibodies; NSP4 is the first described viral enterotoxin, which, by means of an increase in Ca2+ it triggers the diarrheic processes. …”
