    Thermomechanical Performance of fr-4 Laminates in the Manufacturing Process of Printed Circuit Boards. por Rodríguez Vázquez, Carlos Alfonso

    Publicado 2016
    “…In 2006 the Restriction of Hazardous Substances (RoHS) prohibited the use of lead (Pb) in solder paste, which has a melting temperature around 180oC, whereas lead-free solder pastes have a melting point around 230oC, 30oC-40oC higher than Pb solder paste, this has generated PCB thermo mechanical problems due to the temperature increase at which the material is exposed. …”

    Distribución espacial de los vectores de las enfermedades re emergentes (chagas, paludismo y dengue) en el estado de Jalisco, México. por Magallón Gastélum, Ezequiel

    Publicado 2018
    “…A multidisciplinary analytical cross-sectional study, with stratified probabilistic sampling, divided into two aspects: a) Study to estimate point prevalence of the diseases indicated in the open population as well as the spatial distribution of the vectors that transmit these diseases and b) Intentional study in patients Febrile to determine the frequency of these diseases in their active phase. …”

    Evaluación de carbono en ecosistemas terrestres en Tizimín, Yucatán, México por García García, Dora Alicia

    Publicado 2019
    “…The sampling was carried out according to the cardinal points (N, S, E, W). The twigs were separated to place them in paper bags with a capacity of 3 kg, identify them with a code and they will be processed in the weight of each of them, 3 subsamples of each tree will be obtained the answers of the Carbon Laboratories, Technology Laboratory of the Wood and Laboratory of Chemistry of the Faculty of Forestry Sciences of the Autonomous University of Nuevo Leon, where the samples are at a temperature of 75 ° C in a digital drying oven brand Riossa model HCF-102-D for 72 hours . …”

    Bioestratigrafía y microfacies de la formación cuesta del cura (cretácico inferior) en la Cañada Guadalupe del municipio de Iturbide, Nuevo León, México. por Coronado Díaz, Miroslava

    Publicado 2018
    “…The scarcity of information available to the focal points of this research is based on more complex organisms such as ammonoids and other macroscopic organisms, which is why the lack of studies based on foraminifera has not allowed establish more concrete biostratigraphic sequences. …”
