    Contenido de macro y micronutrientes en regosoles en áreas bajo manejo del matorral desértico micrófilo y rosetófilo. por Pérez Pérez, José Eduardo

    Publicado 2018
    “…According to the results obtained, it was found that the use of the aerating roller had beneficial effects due to the fact that the treatments showed better conditions in the layers from 0 to 15 cm deep, making the nutrients available to the plants, however, a cyclic use is recommended since over time the nutrients show a lower availability, as it was shown by the comparison of means between the control and the other aeration roller treatments, where it was found that the 9 application of this implement had better results in Ra11, which was one of the most recent applications in the study area.…”

    Study on the properties of CuSbS₂ and CuSbSeₓS₂₋ₓ thin films for photovoltaic and photodetector applications por Vinayakumar, Vineetha

    Publicado 2019
    “…Our assumptions for alloying it with Se was ground on the fact that incorporation of Se can shift the bandgap of CuSbS2 from 1.5 to 1.2 eV depending on the Se content for much efficient solar light absorption. …”

    Estudio geobiológico de la formación La Virgen y sus facies transicionales en los Potreros de Menchaca y La Virgen, Coahuila. por Gutiérrez Alejandro, Alejandra Guadalupe

    Publicado 2018
    “…Even when this formation was identified and described more tan 50 years ago in pioneer geological studies in northeastern Mexico, and the fact that it is a well-exposed sedimentary unit outcropping in several localities in Coahuila and Chihuahua, the Virgen Formation has remained scarcely studied, especially under a biosedimentological perspective. …”
