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

“…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.  …”

Electrochemical Noise Analysis of Nickel Based Superalloys in Acid Solutions by Gaona Tiburcio, Citlalli, Aguilar M, M.R, Zambrano Robledo, Patricia del Carmen, Estupiñan López, Francisco H., Cabral Miramontes, José Ángel, Nieves Mendoza, Demetrio, Castillo González, E., Almeraya Calderón, Facundo

“…In this paper we study the corrosion behavior of nickel-based superalloys (Inconel 690, Inconel 718, Incoloy 800, Incoloy 825), compared with commercial steels (carbon Steel 1018 and stainless steel 304), in acid (10% H2SO4 and 10 % CH3COOH) and H2O at room temperature, by electrochemical noise technique, with sampling 1024 points per second. Statistical analysis of electrochemical noise technique yielded LI localization index, the type of corrosion and the noise resistance as well as the corrosion rate. …”

Artificial neural network modeling of phenol adsorption onto barley husks activated carbon in an airlift reactor by Loredo Cancino, Margarita

“…Purpose and method of the study: The production of activated carbon from barley husks (BH) by chemical activation with zinc chloride was optimized by using a 23 factorial design with replicates at the central point, followed by a central composite design with two responses (the yield and iodine number) and three factors (the activation temperature, activation time, and impregnation ratio). …”
