Artificial neural network modeling of phenol adsorption onto barley husks activated carbon in an airlift reactor por 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). …”

Resiliencia en el uso de las aplicaciones didácticas interactivas en Estudiantes Universitarios después de la pandemia. Estudio Comparativo por Pérez-Martínez, Katia Site, Saldaña-Pérez, Juan Enrique, Mendoza-Vargas, Marta Magdalena

“…A ambos grupos se les aplico la encuesta llamada: “Escala de Aplicaciones Didácticas Interactivas”, la cual está integrada por 10 ítems de tipo Likert. La primera muestra fue tomada en el año 2018, y la segunda en el año 2023, esto permitió contrastar la diferencia entre sus respuestas, ya que en la primera, la aplicación de Power Point resulto ser la de mayor conocimiento y uso por los estudiantes, sin embargo, después de la pandemia, los estudiantes mostraron una mayor variabilidad ante el uso de las diversas aplicaciones didácticas interactivas, aunque si bien, refieren usar ahora más de una, Power Point sigue siendo la de mayor conocimiento.  …”

Polimorfismo de los genes que codifican para las proteínas VP4, VP7 y NSP4 de rotavirus y su asociación con la severidad de la diarrea por González Ochoa, Guadalupe

“…Abstract Of the viruses that cause gastroenteritis, rotavirus is the main causal agent of severe diarrhea; it causes the fence death 440,000 children per year at world-wide level. Some researchers point to proteins VP4, VP7 and NSP4 like pathogenicity factors; VP4 and VP7 are related with the penetration viral into epithelial cells and the synthesis of neutralization antibodies; NSP4 is the first described viral enterotoxin, which, by means of an increase in Ca2+ it triggers the diarrheic processes. …”
