    Effects of cavitation in common-rail diesel nozzles on the mixing process por López, J. Javier, De la Garza, Oscar A., De la Morena, Joaquín, Martínez Martínez, Sergio

    Publicado 2017
    “…Nevertheless, when the variations of the effective injection velocity and the spray cone angle obtained by comparing a cylindrical nozzle (i.e. a nozzle that promotes the cavitation phenomenon) with a conical nozzle (i.e. a nozzle that inhibits this phenomenon) were analyzed together, it was found that, for the cases studied here, the mixing process worsens with the cylindrical nozzle. …”

    Distributional and Ecological Notes on the Halfbeaks of Eastern Gulf of Mexico, with a Provisional Key for Their Identifification por Contreras Balderas, Salvador, Lozano Vilano, María de Lourdes, García Ramírez, María Elena

    Publicado 1997
    “…Using Banford and Collette (1993), we examined specimens from collections at UANL, UNAM, IPN, and ECOCH and have clarified the Mexican distribution of these species. We here report additional Mexican records of H. meeki, previously known only from United States waters and from the coast of Yucathn, clarify the distribution of H. unifasciatus, and provide the first marine record of the freshwater species H. mexicanus. …”

    Maturing Arc signatures monired by trace element and Hf isotope systematics in the early cretaceous Zacatecas volcanic field, Mexico por Escalona Alcázar, Felipe de Jesús, Delgado Argote, Luis Alberto, Nebel, Oliver, Velasco Tapia, Fernando, Weber, Bodo, Nuñez Peña, Ernesto Patricio

    Publicado 2014
    “…Major and trace element systematics of lava flows and dioritic rocks from laccoliths suggest a cogenetic origin of the Zacatecas Formation and Las Pilas Complex rocks, here combined in the Zacatecas Group. This group represents a single arc succession that evolves from a primitive to mature arc. …”

    Nutrition affects insect susceptibility to Bt toxins por Deans, Carrie A., Behmer, Spencer T., Tessnow, Ashley E., Tamez Guerra, Patricia, Pusztai Carey, Marianne, Sword, Gregory A.

    Publicado 2017
    “…The spread of resistance alleles is the primary explanation for observations of reduced pesticide efficacy over time, but the potential for gene-by-environment interactions (plasticity) to mediate susceptibility has largely been overlooked. Here we show that nutrition is an environmental factor that affects susceptibility to Bt toxins. …”
