(2016)
"El Águila real (Aquila chrysaetos) es una especie importante en los
ecosistemas por su papel como consumidor superior; adicionalmente, es
considerada una especie carismática, bandera, sombrilla, sustituta y de ...
Progress and opportunities for monitoring greenhouse gases fluxes in Mexican ecosystems: the MexFlux network
(Universidad Nacional Autónoma de México, Centro de Ciencias de la Atmósfera, 2013)
"Para entender los procesos de los ecosistemas desde un punto de vista funcional es fundamental entender las relaciones entre la variabilidad climática, los ciclos biogeoquímicos y las interacciones superficie-atmósfera. ...
Water defluoridation with special emphasis on adsorbents-containing metal oxides and/or hydroxides: A review
(Elsevier, 2015)
"Fluoride contamination in drinking water has been recognized as one of the major worldwide problems since this represents a serious threat to human health. The World Health Organization (WHO) recommends the guideline value ...
Evaluation of a membrane bioreactor system as post-treatment in waste water treatment for better removal of micropollutants
(Elsevier, 2016)
"Organic micropollutants (OMPs) such as pharmaceuticals are persistent pollutants that are only partially degraded in waste water treatment plants (WWTPs). In this study, a membrane bioreactor (MBR) system was used as a ...
Mathematical modeling of a composting process in a small-scale tubular bioreactor
(Elsevier, 2017)
"A mathematical model is presented to describe a composting process occurring in a tubular bioreactor. The mathematical model is based on heat and mass transfer phenomena under the continuum approximation. The bioreactor ...
Rheological behavior from light to heavy oils: construction of master curves
(American Chemical Society, 2016)
"In this work, the rheological behavior of heavy and light stabilized (dead) oils is presented. The viscosity measurements were carried out in two different apparatuses to ensure the repetitiveness and accuracy: a Stabinger ...
Facile synthesis and characterization of MnxZn1-xFe2O4/activated carbon composites for biomedical applications
(2016)
"The synthesis of MnxZn1-xFe2O4 ferrites (x = 0.4, 0.5 and 0.6) by means of the co-precipitation method is reported. Furthermore, a composite of Mn0.4Zn0.6Fe2O4/activated carbon was prepared with the mechanosynthesis method. ...
Geoecohydrological mechanisms in semiarid tropical forests: spatial and temporal use of water of two coexisting forest tree species
(2016)
"Las regiones semiáridas ya enfrentan un fuerte estrés hídrico y es probable que
aumente, ya que los cambios en los patrones de lluvia, asociados al cambio
climático, son cada vez más variables. El Centro-Norte de México ...
Effect of the continuous addition of ozone in a biofilter treating ethyl acetate vapors
(2016)
"En este trabajo se analizaron los efectos de la adición continua de ozono (O3) en un
biofiltro para el tratamiento de Acetato de Etilo (EA). Se operaron tres filtros, un
control abiótico para estimar oxidación química, ...
Factores que influyen en la diversidad y distribución de lepidópteros en el Parque Estatal Flor del Bosque, Puebla, México
(2016)
"La constante transformación de los hábitats naturales, resultante de las actividades humanas, está reduciendo las áreas forestales, lo cual puede tener consecuencias para la conservación biológica. La inclusión de los ...
