Análisis geomecánico utilizando el método RMR, de un macizo rocoso ubicado en el km 40 de la carretera Linares – Iturbide. by Garza Pérez, Magdaleny

“…The RMR (ROCK MASS RATING) method proposed by Bieniawski in the 80's will be used as a parameter to classify the quality of the rock mass from a geological engineer point of view, so with complementary data to establish the parameters of the rocky mass for the purpose of slope stability, determining the degree of risk and generating necessary measures to deal with possible damages that could be generated. …”

Thermomechanical Performance of fr-4 Laminates in the Manufacturing Process of Printed Circuit Boards. by Rodríguez Vázquez, Carlos Alfonso

“…In 2006 the Restriction of Hazardous Substances (RoHS) prohibited the use of lead (Pb) in solder paste, which has a melting temperature around 180oC, whereas lead-free solder pastes have a melting point around 230oC, 30oC-40oC higher than Pb solder paste, this has generated PCB thermo mechanical problems due to the temperature increase at which the material is exposed. …”

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). …”

Estructura de edades, densidad y regeneración de Pinus hartwegii en un gradiente de elevación. by Cortés Cabrera, Héctor Enrique

“…Regeneration was sampled in plots, while adult individuals were sampled by the point centered quarter method. Density of adult individuals and regeneration were higher at lower elevations, while individuals with fire scars showed similar density across elevations. …”

Los espacios otros en las ciudades Latinoamericanas. Redefinición de la inclusión desde la exclusión espacial by Padilla Herrera, Diana Karina

“…The present investigation has as general objective to identify the nuances of the mediation from redefining the relation inclusion-spatial exclusion. As a starting point, space, morality, heterotopy and exclusion are considered concepts that guide the conceptual theoretical framework of research, through which new theoretical concepts such as spatialized space, morality and spatial exclusion are proposed. …”
