Caracterización de las sucesiones areno - conglomeráticas del eoceno en la región de las Choapas, Veracruz. por Coronado González, Jesús Margil

“…With the isotope geochemistry of Sm/Nd, the isotopic ratios, model ages and Nd epsilon were obtained, in order to be correlated with data of possible source areas. Rocks with compositions similar to those identified in this work have been described in the Chiapas Massif and the Guichicovi Complex, in the Maya Block; and in complexes exhumed by the Polochic-Motagua Fault System, in Chortis Block.…”

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

“…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). …”

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

“…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

“…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. …”
