    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

    Publicado 2013
    “…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 por Loredo Cancino, Margarita

    Publicado 2013
    “…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). …”

    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

    Publicado 2018
    “…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. …”
