    Numerical study on the combustion process of a biogas spark-ignition engine por Carrera, José, Riesco, José, Martínez, Simón, Sánchez, Fausto, Gallegos, Armando

    Publicado 2013
    “…The combustion process of by biogas is characterized in terms tion of combustion, i. e., depending on the time elapsed while the reac- an of the dura tants (methane and oxygen) are transformed into products (mainly carbon dioxide and water). This study numerically evaluates the way in which the geometrical pa- rameters such as the compression ratio and operating parameters like engine speed, the excess air, the time of spark timing and carbon dioxide content of biogas affect the evolhution of the combustion process. …”

    New Echinoid (Spatangoida: Toxasterinidae) from the Campanian of Coahuila, Northeastern Mexico por Silva Martínez, Luis Encarnación, Blanco Piñón, Alberto, De León González, Jesús Ángel, Rodríguez Vela, Hidalgo

    Publicado 2016
    “…The morphology of the specimens (test with a cordiform aboral region) as well as the sedimentary environment reported at the Austin Formation, suggests that this species represents an infaunal and detritivorous dweller living in a shallow water environment within the continental shelf. This is consistent with the more actual knowledge for other species of Diplodetus Keywords: Echinoids, Diplodetus, Upper Cretaceous, Campanian, Austin Formation, NE Mexico. …”
