La lenteja de agua (Lemna minor L.): una planta acuática promisoria
(2014-05-06)
The main morphological and ecological characteristics of the aquatic plant Lemna minor L. are described,
as well as its use as food complement for domestic animals, and in phytoremediation for its ability to absorb
nutrients ...
Diseño de una metodología de selección de sitios para monorrellenos de lodos papeleros
(2014-05-08)
The wastewater treatment at paper industry that uses recycled fibers as one of its raw materials generates
a sludge rich in cellulose fibers, which once dehydrated is called “paper waste”. This waste has become
an ...
Evaluación de procesos biológicos unitarios en la remoción simultánea de nutrientes para minimizar la eutrofización
(2013-11-18)
Two different systems of biological treatment were operated (anaerobic-anoxic-aerobic –A2O–, namely, arrangement I, and aerobic-anoxic, namely, arrangement II). After modification by the addition of AnoxKaldnes as a support ...
Evaluación del comportamiento de arcillas sometidas a diferentes tiempos de exposición a altas temperaturas
(2013-11-15)
Laboratory tests were performed in order to evaluate the effects on the index properties, volumetric behavior and monotonic uniaxial strength of two clays caused by the application of different temperatures (150, 225 and ...
Ajuste de curvas mediante métodos no paramétricos para estudiar el comportamiento de contaminación del aire por material particulado PM10
(2013-12-16)
One of the main air pollutants is the particulate matter whose aerodynamic diameter is less than 10 micrometers, usually referred as PM10. It is a fact that the PM10 behavior in the air varies in an irregular way, and also ...

(2013-11-07)
This paper presents the results of treatment with ozone and subsequent fractionation of dissolved organic matter (DOM) from secondary effluent from Cerro de la Estrella wastewater treatment plant located in Mexico City. ...
Criterios sismológicos para seleccionar acelerogramas reales de la Red Nacional de Acelerógrafos de Colombia para su uso en análisis dinámicos
(2013-11-12)
The use of real accelerograms as input in dynamic analysis is desirable as they provide realistic information about the nature of the strong ground motion; in addition, accelerograms capture different characteristics that ...
Impactos de las carreteras sobre la fauna silvestre y sus principales medidas de manejo
(2014-05-07)
The purpose of this paper is to present the impact of roads on wildlife and to evaluate the ways to
manage these impacts. Various foreign articles and studies were analyzed as well as environmental impact
studies of roads ...
Modelamiento de la cinética de hidrólisis enzimática de proteínas del plasma bovino
(2013-11-12)
A kinetic model was used to study the reaction rate of hydrolysis of bovine plasma proteins and alcalase 2.4 L, in a batch reactor. The influence of variables, such as the concentration of initial enzyme substrate and the ...
Annual and diurnal cycles of the inverse relation between plant transpiration and carbon sequestration
(2014-05-09)
El conocimiento de los ciclos biogeoquímicos y, en especial, de los balances de carbono es clave para
la validación de los modelos de cambio global para el presente y el futuro cercano. Como consecuencia, en
el mundo se ...
