    Efectos de los parámetros de inyección sobre el proceso de mezcla en un motor diesel. por Torres Garza, Omar

    Publicado 2016
    “…ABSTRACT Diesel engines have been widely used because of their high efficiency for the generation of energy, as they allow the use of alternative fuels (biodiesel) and the use of a multiple injection strategy, which lead to a reduction of gas emissions Of the combustion and to avoid a greater wear in the nozzles and pumps of injection, nevertheless the use of a strategy of multiple injection demands to deepen in the effects of the parameters of injection on the process of mixing in a diesel engine. …”

    Inversión conjunta de sísmica de refracción y sondeos eléctricos verticales utilizando programación evolutiva. por Merlo Mejía, Jorge Luis

    Publicado 2017
    “…Therefore, alternative techniques have been explored in the search for an optimal solution, within which metaheuristic techniques can be mentioned, since knowing the solutions space, the inverse problem can be posed as an optimization problem in which our search (given certain constraints) can be reduced to randomly find an optimum that provides a solution to the problem. …”

    Caracterización del perfil de expresión génica del núcleo accumbens en la descendencia de ratas wistar con adicción a la comida hipercalórica. por Montalvo Martínez, Larisa Jajaira

    Publicado 2017
    “…Transmission of operant behavior is greater in the offspring from mothers undergoing nutritional programming. In addition, we have identified by global expression microarrays that subjects with addictive behavior exhibit a genomic signature involving 8 genes present in the neurotransmitters exocytosis processes (Syt17, Stx1a), synaptic signaling (Chrm3, Gpr149); cytoskeleton remodeling and synaptic plasticity (Sema3e, Abi3bp), also in processes of excessive consumption of alcohol in both men and animal models (Hbb-b1, Polr3k, Mir30a). …”

    Uso de dos fuentes de estrógenos: benzoato de estradiol vs cipionato de estradiol para sincronizar el estro y la ovulación en vacas holstein-friesian por Iñiguez Montejano, Ana Lilian

    Publicado 2019
    “…Abstract The objective of this study was to measure the serum estrogen concentration in Holstein cows treated with two estrogen sources, estradiol cypionate (EC) and estradiol benzoate (BE), also evaluating the relationship that these sources of exogenous estrogens have with reproductive efficiency. Twenty one Holstein-Friesian cows divided into 3 treatments were used (n=7) (treatment 1 Group BE, treatment 2 Group CE and treatment 3 Control group). …”

    Caracterización clonal de aislamientos clínicos de Stenotrophomonas maltophilia productores de biopelícula por Montoya Hinojosa, Edeer Iván

    Publicado 2020
    “…For the analysis of the genetic diversity of S. maltophilia, common typing techniques such as pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) have been used. The objective of this work was to determine the clonal diversity of clinical isolates of S. maltophilia biofilm producers. …”
