    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. …”

    Análisis geomecánico utilizando el método RMR, de un macizo rocoso ubicado en el km 40 de la carretera Linares – Iturbide. por Garza Pérez, Magdaleny

    Publicado 2017
    “…The RMR (ROCK MASS RATING) method proposed by Bieniawski in the 80's will be used as a parameter to classify the quality of the rock mass from a geological engineer point of view, so with complementary data to establish the parameters of the rocky mass for the purpose of slope stability, determining the degree of risk and generating necessary measures to deal with possible damages that could be generated. …”

    Síndrome de Burnout en instructores de inglés en escuelas primarias públicas. por Nava Gutiérrez, Juan Diego

    Publicado 2016
    “…With this as background, this project was formulated from interest in addressing the burnout syndrome instructors who teach English in public primary schools in the metropolitan area of Monterrey, performing comparative analyzes based on gender, area where they work and level of studies reached at the time of application; by a non-experimental design, transversal, and descriptive ex postfacto, with voluntary participation of 281 instructors. In order to collect data, it was considered to use the Burnout Questionnaire for Teachers Revised, with 66 items in 5 points Likert scale, to measure emotional exhaustion, depersonalization and lack of personal accomplishment, with a total α = 0.92 in the original study. …”
