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 ...
Computational Fluid Dynamics Simulation of Coal Gasification in a Circulating Fluidized Bed Reactor
(2019-10-09)
One of the applications of coal as a fuel is the production of gas through circulating fluidized bed technology. The modeling of these systems allows verifying and optimizing the design and operation parameters of gasifiers ...
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. ...
Survival Engineering and the Game of Knowledge: A Ludic Form of Teaching and Learning in Engineering
(The Future of Higher Education in the Middle East and Africa, 03/27/2018)
Within the engineering pedagogy, it must be remembered that students learn in many different ways: seeing, hearing, thinking, acting, drawing analogies, and building mathematical models in the area of science and technology. ...
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 ...
Water Quality Evaluation of the Cabra River Using Biological Indicators
(2019 7th International Engineering, Sciences and Technology Conference (IESTEC)2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2019-10-09)
The objective of this study was to evaluate the water quality of the Cabra River through the use of aquatic macroinvertebrates implementing the EPT and BMWP/Pan indexes. The diversity of orders and families of macroinvertebrates ...
