Diferencias de género en las actitudes hacia las matemáticas = Gender differences in attitudes toward mathematics por De la Torre Gamboa, Martha Patricia, Ramírez Martínez, Martín

“…Abstract The results of previous research do not allow us to generalize the existence of gender differences in attitudes toward mathematics, however they coincide in the majority in pointing out that men have a greater extrinsic motivation, that they show greater confidence in their future achievements in the area of mathematics, less anxiety about mathematics and attribution of success to external causes. …”

Electrochemical Noise Analysis of Nickel Based Superalloys in Acid Solutions por 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. …”

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

“…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.  …”
