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.…”

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. …”
