    La satisfacción de clientes/deportistas y trabajadores en entidades deportivas como determinante de los servicios deportivos. por Reyes Robles, Marina

    Publicado 2018
    “…Results: satisfactory indices were obtained within the exploratory and confirmatory factor analyzes, the values resulting from the reliability: Cronbach’s alpha, composite reliability and average variance extracted were acceptable for most if the factors except for the facility factor of the client/athlete survey that did not meet the recommended value, the correlation indexes, it is observed that all the factor of the poll of client/athlete survey as for the workers correlate positive and significantly among all the factors. …”

    Implementación del sistema de producción de bioetanol en un reactor híbrido tipo batch para su uso en un motor de combustión interna. por Lucio López, Alex Nibardo de

    Publicado 2018
    “…Finally, the physicochemical characterization, the gas chromatography analysis to know the purity and finally, the injection in a CFR engine were carried out, in order to validate the quality of the gasoline-bioethanol mixture in two compositions E5% and E10%. From these mixtures were evaluated the levels of average maximum pressure in the chamber, duration of the first phase of combustion and autoignition values. …”
