    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. …”

    Polimorfismo de los genes que codifican para las proteínas VP4, VP7 y NSP4 de rotavirus y su asociación con la severidad de la diarrea por González Ochoa, Guadalupe

    Publicado 2006
    “…Abstract Of the viruses that cause gastroenteritis, rotavirus is the main causal agent of severe diarrhea; it causes the fence death 440,000 children per year at world-wide level. Some researchers point to proteins VP4, VP7 and NSP4 like pathogenicity factors; VP4 and VP7 are related with the penetration viral into epithelial cells and the synthesis of neutralization antibodies; NSP4 is the first described viral enterotoxin, which, by means of an increase in Ca2+ it triggers the diarrheic processes. …”
