Evaluación de un protocolo de entrenamiento canino utilizando una línea celular b16f10 para la detección de melanoma en un modelo murino por Aguirre Alberto, Raúl Abreu

“…Therefore we assume that the cell line and the biological samples emit common volatile signals that allow the dog to discriminate them, however, the results of the first tests indicate that the spontaneous change of the matrix in which they are found causes doubt and hesitation when pointing out the samples of mice with cancer. …”

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. …”
