Cuadro de mando integral para el diseño y validación de instrumentos para valorar el desempeño académico de docentes
(2009-12-22)
La valoración de la labor docente es un pilar de la acreditación universitaria. En un momento, particularmente sensible relacionado a esta tendencia global y a la imagen que emerge de las
diferentes unidades académicas y ...
Behavioral and Physical Factors Influencing Energy Building Performances in Mediterranean Climate
(2015-11-01)
The residential sector is used to test the relative roles of socioeconomic and behavioral variables of occupants as compared with the climate and physical building characteristics. The study is carried out considering a ...
Airflow and insulation effects on simultaneous syngas and biochar production in a top-lit updraft biomass gasifier
(2017-10-11)
The objective of this study was to understand the effect of airflow and insulation on syngas and biochar generations of rice hulls and woodchips in a top-lit updraft gasifier. Biochar yield decreased with increasing airflow. ...
Adsorption of Cu ions onto a 1.10 phenanthroline-grafted Brazilian bentonite
(2003-02-01)
The grafting, by chemical adsorption, of molecular 1.10-phenanthroline (OP) onto some Brazilian bentonite (montmorillonites) was studied to improve their adsorptive capacities to remove Cu ions from synthetic wastewater. ...
Numerical study of inherent deformation produced in thick plates through bending by line heating
(2006-06)
In ship building, line-heating is widely employed as an effective method to form steel plate with complex 3-dimensional carved geometries. However the plate bending by line heating is strongly dependent on skills. To ...
The Effect of Biomass Physical Properties on Top-Lit Updraft Gasification of Woodchips
(2016-04-12)
The performance of a top-lit updraft gasifier affected by biomass (pine wood) particle size, moisture content and compactness was studied in terms of the biochar yield, biomass burning rate, syngas composition and tar ...
Nitrous Oxide Fluxes from a Commercial Beef Cattle Feedlot in Kansas
(2014-03-10)
Emission of greenhouse gases, including nitrous oxide (N2O), from open beef cattle feedlots is becoming an environmental concern; however, research measuring emission rates of N2O from open beef cattle feedlots has been ...
Experimental research on the effects of water application on greenhouse gas emissions from beef cattle feedlots
(2014-04-30)
The effect of water application (e.g., through rainfall or sprinkler system) on emissions of greenhouse gases (GHGs), such as nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2), from pen surfaces of open-lot beef ...
The Balance Score Card for the Design and Validation Instrumens to Measure the Academic Teachers´s Achievement and Performance
(2012-07-04)
The evaluation of faculty work is critical for the university accreditation. Moreover, particularly sensitive to this related tendency of faculty work evaluation; it is necessary to go beyond the knowledge factor and ...
Numerical analysis of the straightening process of thin plate structures by elastic FEM based on the inherent strain method
(2012-12)
Welding distortion is practically an expected feature in shipbuilding, with a few exceptions; when thick plates are used, for example. Nowadays, the trend is to use thinner plates in order to reduce weight, aiming to reduce ...
