A synthetic biofilter media for ammonia (NH3) removal
(2012)
In this work, a patented biofilter media is used in treating air contaminated with ammonia (NH3). The data shows up to 200 ppm of NH3 can be removed with over 93% removal efficiency at 30 s Empty Bed Residence Time (EBRT). ...
Efficiency comparison of various design schemes for copper-chlorine (Cu-Cl) hydrogen production processes using Aspen Plus software
(2012-11)
In this study, simulation models are developed to analyze, design and optimize the Cu–Cl cycles using the Aspen PlusTM chemical process simulation package. Energy, exergy and yield effectiveness of the process, based on ...
Comparison of diesel emission experiments in view of the environment: A case study at Dubai
(2012)
Because of the nature of the diesel engine combustion process, such engines produce more toxic emissions, more visible smoke and odour than gasoline engines. This has led to an increasing concern about the possible effects ...
Prediction of Backwater Level of Bridge Constriction using ANN
(2012-12)
Bridge constriction in channels usually causes afflux which results in increase in backwater level well above the normal level and may possibly result in overflow on the flood plain surrounding the channel during flooding ...
Thermodynamic analysis of a novel integrated geothermal based power generation-quadruple effect absorption cooling-hydrogen liquefaction system
(2012-04)
In this paper, we propose a novel integrated geothermal absorption system for hydrogen liquefaction, power and cooling productions. The effect of geothermal, ambient temperature and concentration of ammonia-water vapor on ...
Numerical Simulation of Vapor Flow and Pressure Drop across the Demister of MSF Desalination Plant
(Elsevier, 2012-03)
This paper presents a numerical simulation of the water vapor flow in an MSF flash chamber along with the pressure drop across the demister. The demister is a simple porous blanket of metal wires mesh (usually made of ...
Space size relative to prey width and total cover in an area both influence the habitat choices of freshwater angelfish Pterophyllum scalare in mesocosms
(2012)
Prey survivorship can vary with average space size/prey width (Sp/Py) and total cover within an area (Ct/At). Hypotheses predict that prey survivorship is maximized at intermediate Sp/Py values and that prey survivorship ...
Efficiency Optimization of a DSP-Based Standalone PV System Using Fuzzy Logic and Dual-MPPT Control
(2012-04)
This paper presents a new digital control scheme for a standalone photovoltaic (PV) system using fuzzy-logic and a dual maximum power point tracking (MPPT) controller. The first MPPT controller is an astronomical two-axis ...
Removal of diclofenac potassium from wastewater using clay-micelle complex
(2012-06)
The presence of an ionized carboxyl group in the widely used non-steroidal anti-inflammatory (NSAID) drug diclofenacpotassium results in a high mobility of diclofenac and in its low sorption under conditions of slow sand ...
Foreign Investment and Ethics: How to Contribute to Social Responsibility by Doing Business in Less-Developed Countries
(Springer, 2012-03)
Do foreign direct investment (FDI) and international business ventures promote positive social and economic development in emerging nations? This question will always prove contentious. First, the impacts differ according ...
