Identifying factors influencing the corrosion rate of steel using nonparametric statistics by Nieves Mendoza, Demetrio, Gaona Tiburcio, Citlalli, Hervert Zamora, H.L., Méndez, R.C, Castro Borges, Pedro, Borunda Terrazas, A., Zambrano Robledo, Patricia del Carmen, Almeraya Calderón, Facundo

“…Nonetheless, given the difficulty in obtaining adequate data, it is common not to have random and homogeneous samples in order to conduct parametric statistical tests (which follow a known distribution). The present study reports results from the use of a non-parametric statistical test (which does not follow a known distribution) known as the Mood test of median differences which was conducted to analyze the corrosion rate of concrete beams exposed to different environmental conditions. …”

Accessible location of mobile labs for COVID-19 testing by Villicaña Cervantes, Dianne Larissa, Ibarra Rojas, Omar Jorge

“…In response, we designed a Biased Random-Key Genetic Algorithm to solve the defned problem; this is capable of obtaining high-quality feasible solutions over large numbers of instances in seconds. Moreover, we present insights derived from a case study into the locations of COVID-19 testing mobile laboratories in Nuevo Leon, Mexico. …”

Managing raw materials of vegetable origin increases fungal indoor concentration in food companies by Elizondo Zertuche, Mariana, Martínez Carranza, Karen, Orue, Nydia, de Jesús Treviño Rangel, Rogelio, Robledo Leal, Efrén Ricardo

“…Penicillium, Cladosporium and Aspergillus were the most commonly isolated genus, with Penicillium being the only genus to be present in every area sampled. Neither the companies’ location nor their room temperature influenced the fungal densities significantly, however, companies using vegetable raw materials had a significantly greater concentration of fungi than the rest of the companies. …”

Identification and in silico structural and functional analysis of a trypsin-like protease from shrimpMacrobrachium carcinus by Viader Salvadó, José María, Aguilar Briseño, José Alberto, Gallegos López, Juan A., Fuentes Garibay, José A., Alvarez González, Carlos Alfonso, Guerrero Olazarán, Martha

“…Macrobrachium carcinus (Linnaeus, 1758) is a species of freshwater shrimp widely distributed from Florida southwards to southern Brazil, including southeast of Mexico. In the present work, we identified a putative trypsin-like protease cDNA fragment of 736 nucleotides from M. carcinus hepatopancreas tissue by the 3′RACE technique and compared the deduced amino acid sequence to other trypsin-related proteases to describe its structure and function relationship. …”

Análisis estructural de la zona norte del bloque de San Julián, Zacatecas México by Guerra Roel, Rafael

“…Por otro lado, están los cinturones orogénicos cordilleranos los cuales se desarrollan en lugares donde se tiene un ambiente de subducción activo en los márgenes de placas convergentes en donde por lo general el metamorfismo, el engrosamiento de la corteza continental y un cinturón de pliegues y cabalgaduras (CPC) localizado en la parte más alejada de la trinchera son las principales características presentes. Los CPC se localizan en muchas partes del mundo, prácticamente suceden en donde alguna capa de la corteza superior, sufre acortamiento horizontal significativo, generando pliegues y fallas relacionados con cabalgaduras sin sobrepasar las condiciones de metamorfismo de bajo grado. …”
