La Distribución Funcional del Ingreso en Las Empresas Mexicanas by Peralta-Solorio, Ernesto Felipe

“…Por otra parte, las grandes empresas tienen un papel opuesto, generan poca ocupación y basta producción, esto implica desigualdad distributiva funcional del producto, del ingreso para los factores capital y trabajo; los datos originales usados son del Censo Económico 2014, que se contrastan con los que resultan de aplicarles la función de producción Cobb – Douglas en un marco informativo amplio, de ocupación según la Encuesta Nacional de Ocupación y Empleo (ENOE) y de valor agregado, del Sistema de Cuentas Nacionales de México (SCNM); contraste entre lo que se reporta oficialmente y lo que un modelo teórico sugiere, con extensión hacia las micro, pequeñas y medianas empresas; de este panorama contrastante se derivan conclusiones y recomendaciones.…”

Impacto ambiental originado por los lixiviados del relleno sanitario municipal de Linares N.L. México by Cruz Vega, Carlos Ramón

“…The results revealed an existence of a hydro-geochemical evolutional pattern from a composition of bicarbonate-calcium to a bicarbonate-sulfate-calcium, although two of the wells (P1 and P2), placed down stream of the sanitary landfill showed a composition that left this pattern. …”

FeS₂/ZnO core/shell nanowires: structural, optical and electrochemical properties. by Retana Betancourt, María Fernanda

“…Altough, many efforts have been done in order to find the characteristics and properties that allow the subsequent production and commercialization, hybrid solar cells represent an interesting option for this purpose. The composition in the photoactive layer is key in order to obtain high values of efficiencies and where the use of nanosized materials with one-dimensional morphology embedded into polymeric matrix allows the improvement of their optoelectronic properties. …”

Reliability of X7R Multilayer Ceramic Capacitors During High Accelerated Life Testing (HALT) by Hernández López, Ana María, Aguilar Garib, Juan Antonio, Guillemet Fritsch, Sophie, Nava Quintero, Román Jabir, Dufour, Pascal, Tenailleau, Christophe, Durand, Bernard, Valdez Nava, Zarel

“…It is known that the reliability of MLCCs depends on their composition, processing, and operating conditions. In this present work, we analyzed the lifetime of three similar X7R type MLCCs based on BaTiO3 by conducting High Accelerated Life Tests (HALT) at temperatures up to 200 ◦C at 400 V and 600 V. …”

Testing evolutionary models to explain the process of nucleotide substitution in gut bacterial 16S rRNA gene sequences by Garcia Mazcorro, José F.

“…The 16S rRNA gene has been widely used as a marker of gut bacterial diversity and phylogeny, yet we do not know the model of evolution that best explains the differences in its nucleotide composition within and among taxa. Over 46 000 good-quality near-full-length 16S rRNA gene sequences from five bacterial phyla were obtained from the ribosomal database project (RDP) by study and, when possible, by within-study characteristics (e.g. anatomical region). …”

Experimental evidence of icosahedral and decahedral packing in one-dimensional nanostructures by Velázquez Salazar, J. Jesús, Esparza, Rodrigo, Mejía Rosales, Sergio, Estrada Salas, Rubén, Ponce, Arturo, Deepak, Francis Leonard, Castro Guerrero, Carlos Fernando, Yacamán, Miguel José

“…These nanowires, formed by the reaction of a mixture of metal salts (Au and Ag) in the presence of oleylamine, are obtained when the chemical composition is specifically Ag/Au = 3:1. The experimental images of the icosahedral nanowires have a high likelihood with simulated electron micrographs of structures formed by two or three Boerdijk Coxeter Bernal helices roped on a single structure, whereas for the decahedral wires, simulations using a model of adjacent decahedra match the experimental structures. …”
