    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. …”

    ESTUDIO PILOTO PARA EL AISLAMIENTO DE VIBRIO SPP EN OSTRAS (CRASSOSTREA RHIZOPHORAE) CAPTURADAS EN LA CIÉNAGA DE LA VIRGEN, CARTAGENA, COLOMBIA por López, Lersy, Manjarrez, Ganiveth, Herrera, Lilibeth, Montes, Ana, Olascuaga, Yuranis, Ortega, Rolando

    Publicado 2010
    “…Culture mediums and Biochemical test was used for Vibrio´s isolation and identification. the predominantVibrio´s species were V. alginolyticus (23%), V fluvialis  (20%), V. parahaemolyticus (10%), V. carchariae and Vmimicus (13%), V. vulnificus, cincimatiensis and V. campbelli (7%).   The sampling point with the highest number ofVibrio isolation was Mangles, cielo mar sector, which also contributed with 30% of the total of all species isolated although the difference was of no statistical significance due to their homogenous distribution.  100% of the sampling points showed cloudy water due to the presence of organic matter in suspension and visible solid waste, Thus, Factors influencing Vibrios proliferation on oysters maybe related with the Ciénaga characteristics.  …”
