Analysis and prediction of welding distortion in complex structures using elastic finite element method
(2012-07)
The Elastic Finite Element Method based on the inherent strain theory is used to predict the welding distortion of ship structures. In addition, a method to predict welding distortion of complex structures by using elastic ...
A numerical study of parameters governing an inherent deformation database of plates formed by line heating
(2008-08)
As an overall strategy to improve the accuracy of the forming process, the authors pay attention to those factors which may influence the inherent deformation of plates formed by line heating. In order to identify those ...
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 ...
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 ...

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. ...
Introduction to the Application of Phase Change Materials under Tropical Climate of Panama
(2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2016-10-09)
Phase change materials (PCM) are materials with the ability to store a large amount of energy (latent heat) during their change from solid to a liquid phase. This takes place at a certain melting temperature. Amid the ...
Water Quality Evaluation of the Cabra River Using Biological Indicators
(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 ...
Development of a Prototype for Solar Radiation Exploitation on Galvanized Metal Roofs in Panama
(2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2019-10-09)
The solar energy is an inexhaustible resource available in many areas of our planet. The objective of this investigation is to develop a prototype that takes advantage of the incident solar energy on metal roofs of the ...
