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

“…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

“…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. …”

Review of the Capitellidae (Annelida, Polychaeta) from the Eastern Tropical Pacific region, with notes on selected species por García Garza, María Elena, De León González, Jesús Ángel

“…Of these, 6 species were erroneously recorded for the region (Decamastus gracilis Hartman, 1963; D. nudus Thomassin, 1970; Mastobranchus variabilis Edwing, 1984; Notomastus aberans Day, 1957; N. americanus Day, 1973; N. latericeus Sars, 1851) and 5 species are found here to be questionable records for the Eastern Tropical Pacific (Capitella capitata (Fabricius, 1780); Dasybranchus glabrus Moore, 1909; D. lumbricoides Grube, 1878; Notomastus lineatus Claparède, 1870 and N. tenuis Moore, 1909).…”

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

“…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. …”

A Core-Offset Mach Zehnder Interferometer Based on A Non-Zero Dispersion-Shifted Fiber and Its Torsion Sensing Application por Huerta Mascotte, Eduardo, Sierra Hernandez, Juan, Mata Chavez, Ruth, Jauregui Vazquez, Daniel, Castillo Guzmán, Arturo Alberto, Estudillo Ayala, Julián Moisés, Guzman Chavez, Ana, Rojas Laguna, Roberto

“…The MZI was implemented by core-offset fusion splicing one section of a NZ-DSF fiber between two pieces of single mode fibers (SMFs). Here, the NZ-DSF core and cladding were used as the arms of the MZI, while the core-offset sections acted as optical fiber couplers. …”

Isolation ofBdellovibriosp. from soil samples in Mexico and their potential applications in control of pathogens por Oyedara, Omotayo Opemipo, De Luna Santillana, Erick de Jesus, Olguin Rodriguez, Omar, Guo, Xianwu, Mendoza Villa, Marco Antonio, Menchaca Arredondo, Jorge Luis, Elufisan, Temidayo Oluyomi, Garza Hernandez, Javier Alfonso, García León, Israel, Rodríguez Pérez, Mario Alberto

“…They were observed to be different strains based on hit locus and prey range analyses. Here, the first report on Bdellovibrio strains isolated from soil in Mexico corroborates earlier report indicating that populations of Bdellovibrio found in soil are heterogeneous thereby the need to identify the various strains.…”

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.

“…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. …”
