Seed germination of Opuntia species from an aridity gradient in Central Mexico
(2010)"In the Mexican highlands there are several aridity gradients affecting Opuntia species composition and its biological function. Since environmental variations can affect plant traits like seed morphology as well as related ... -
Shifts in Climatic Niche Occupation in Astrophytum Coahuilense (H. Möller) Kayser and Its Potential Distribution in Mexico
(MDPI AG, 2019)"It has frequently been reported that species with strong niche conservatism will not be able to adapt to new climatic conditions, so they must migrate or go extinct. We have evaluated the shifts in climatic niche occupation ... -
Simulación númerica de la dispersión de aerosoles producidos por incendios forestales en el área de protección de flora y fauna La Primavera, Jalisco.
(2009)"Los incendios forestales son un problema ambiental global que afecta los ecosistemas forestales del planeta. La quema de biomasa ocasiona daños en la vegetación, pérdida de especies animales, pérdida de cobertura de suelo ... -
Simultaneous adsorption of Pb(Ii)-Cd(Ii), Pb(Ii)-phenol, and Cd(Ii)-phenol by activated carbon cloth in aqueous solution
(2015-01)"The aim of the present work was to determine the effect of the simultaneous adsorption of lead(II)-cadmium(II), lead(II)-phenol, and cadmium(II)-phenol by activated carbon cloths (ACCs). Three commercial ACCs were ... -
Sintesis de redes poliméricas interpenetradas para la remoción de fluoruro y cadmio en solución acuosa.
(2010)"Las redes poliméricas interpenetradas (IPN´s) son combinaciones de dos o más polímeros en forma de red, donde al menos uno de ellos es sintetizado o entrecruzado en la presencia del otro polímero. Durante la investigación ... -
Síntesis de un compatibilizante para poliéster y poliolefinas, con base en redes interpenetradas poliméricas
(2012-09)"Las necesidades de la sociedad actual van en aumento incesante, por lo que es de imperiosa necesidad optimizar los recursos para que las generaciones futuras no sufran de escasez ni de problemas de contaminación a causa ... -
Síntesis de xerogeles de sílice como soporte de partículas de hidro(óxidos) de hierro para la absorción de arsénico presente en la solución acuosa.
(2011)"La presencia de arsénico disuelto en agua subterránea es un problema mundial de alta prioridad. La promulgación del nivel de concentración máxima de arsénico en el agua potable (10 μgL-1, WHO) se ha reflejado en el aumento ... -
Síntesis y evaluación electroquímica de compositos con base en óxido de grafeno y poli(ácido acrílico) para la remoción y/o detección de contaminanates en agua.
