Las ecuaciones de Rachford-Rice comúnmente utilizadas para determinar la distribución másica entre dos fases en equilibrio en el contexto del denominado Problema Flash, se modificaron con la intención de poder describir también estados de equilibrio donde las contribuciones a la energía del sistema, que tienen origen en la región interfacial...
Introducción: La Somnolencia Diurna (SD) es uno de los dos principales síntomas de los Trastornos De Sueño (TDS) y es un factor de riesgo de accidentes. La Escala de Somnolencia Epworth (ESE) permite evaluar la presencia y severidad de la SD. Actualmente se conoce que la SD es un síntoma...
In this work, chitosan cross-linked cellulose fibers were prepared using non-toxic and eco-friendly procedures in order to confer antimicrobial properties to cellulose fibers. Initially, commercial chitosans and chitooligosaccharides were physico-chemically characterized and the latter were tested by assays in vitro. Chitosan was selected based on molecular weight and acetylation degree....
Introduction: Asthma is a chronic inflammatory airway disease, which affects nearly the 15% of Mexican children. Increasing evidence shows that single nucleotide polymorphisms (SNPs) in more than 100 candidate genes are important risk factors to develop this disease and they have ethnic differences. Objective: The present study was undertaken to...
Los hongos entomopatógenos permiten el control de los insectos que son plagas de cultivos de importancia económica, así como de insectos vectores de enfermedades de salud pública en humanos y animales de cría, de una manera ecológica, segura y económicamente viable. El potencial patógeno de estos hongos esta dado por...
Fungal biofilters have shown high elimination capacities (ECs) for hydrophobic volatile organic compounds (VOCs). It has been hypothesized that the above is due to the formation of aerial hyphae, which increase the area of transfer and hydrophobic surfaces that favor the partition of these compounds. Both physiological characteristics, aerial mycelium...
Malnutrition is distributed widely throughout the World and is a particular problem in developing countries. Actually, recent studies estimate that 10 million of children younger than 5 years of age die in developing countries; more than 50% of deaths in children are attributed to conditions preventable: the malnutrition contributes to...
The fish wastes are generally dumped or discarded causing environmental pollution and off odours. However, they represent large resources that are currently underutilized. The purpose of this study was the lactic acid fermentation of three sources of fish wastes: Shrimp by catch (SC), Sphyraena ensis wastes (SB) and mixture of...
Pteronotus davyi es un murciélago tropical que en México presenta un área de distribución que abarca actualmente las vertientes del pacífico y del golfo de México con unión en el Istmo de Tehuantepec, hasta la Península de Yucatán. Evaluamos las relaciones filogeográficas entre 18 poblaciones en México utilizando datos de...
