Research ArticleOpen accessIn the abstractSimultaneous Thermodynamic and Kinetic Parameters Determination Using Differential Scanning CalorimetryNader Frikha, Mohamed Bouroukba, Eric Schaer, Jean-Leon HouzelotProblem statement: The determination of reaction kinetics is of major importance, as for industrial reactors optimization as for environmental reasons or energy limitations. Although calorimetry is often used for the determination of thermodynamic parameters alone, the question that arises is: how can we apply the Differential Scanning Calorimetry for the determination of kinetic parameters. The objective of this study consists … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 7,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioactive Compounds Screening from Zingiberaceae Family as Influenza A/Swine Flu Virus Neuraminidase Inhibitor through Docking ApproachUsman Sumo Friend Tambunan, Fadilah, Arli Aditya ParikesitProblem statement: Influenza A/H1N1 is a disease caused by infection of influenza a virus subtype H1N1. It is a major health problem in tropical and subtropical countries. This virus constantly mutates and consequently will be developed into new drug-resistant strains. Approach: In this research, we have conducted docking study to screen bioactive compounds from Zingiberaceae family, which has a role … …OnLine Journal of Biological Sciences, Vol. 10, Issue 4 · 31 Dec 2010 · 8,623 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Development in Biological Process for Wastewater Treatment to Produce Renewable FuelKadhum M. Shabeeb, Khalid A. Sukkar, Rana A. Azeez et al.Problem statement: Hydrogen is a clean energy source. Bio-conversion of biomass to generate hydrogen has been achieved using anaerobic fermentation of some well-defined materials, in wastewater. No data available on hydrogen yielded from wastewater using inoculum extracted from Iraqi municipal wastewater treatment plant. Approach: This study investigated the effects of substrate concentration, initial pH and process temperature on biohydrogen production … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,255 accessesView PDFCite
Research ArticleOpen accessIn the abstractSupercritical Ethanol Liquefaction of Swine Manure for Bio-Oils ProductionShuangning Xiu, Abolghasem Shahbazi, Lijun Wang, Carlington W. WallaceProblem statement: Environmental problems associated with animal waste are the most critical challenges faced by the US intensive confinement livestock industries. There is an import and urgent need to develop an efficient way to reduce the pollution of animal waste while extracting valuable energy. Supercritical liquefaction processing of swine manure into a liquid fuel was considered as a cost-effective approach … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpgrading of Bio-Oil into High-Value Hydrocarbons via HydrodeoxygenationMurni M. Ahmad, M. Fitrir R. Nordin, M. Tazli AzizanProblem statement: World energy consumption is forecasted to grow significantly for the foreseeable future with fossil fuel remains the governing energy source. The demand in the need to explore alternative fuel source was further triggered by the overwhelmingly inconsistent cost of gasoline. Bio-oil is an alternative energy source produced from pyrolysis of biomass. However it is undesirable as a ready … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn-Cylinder Heat Transfer Characteristics of Hydrogen Fueled Engine: A Steady State ApproachM. M. Rahman, Khalaf I. Hamada, M. M. Noor et al.This study presents in-cylinder heat transfer characteristics of a single cylinder port injection Hydrogen fueled Internal Combustion Engine (H2ICE) using a steady state approach. Problem statement: The differences in characteristics between hydrogen and hydrocarbon fuels are led to the difference in the behavior of physical processes during engine cycle. One of these processes is the in-cylinder heat transfer. Approach: One … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeatures Study on Target Fragmentation in the Collisions Of 24Mg and 28Si with Emulsion Nuclei at 3.7A GeVA. Abd EL-DaiemProblem statement: The process of nuclear fragmentation in interactions of 3.7A GeV 24Mg and 28Si nuclei with the different target nuclei in a nuclear emulsion have been investigated. Approach: The probability of interactions without any projectile fragment with charge Z≥2 is zero for hydrogen target, but increases by increasing the mass of the target. Results: The disruption of a projectile … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 7,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractHydrophobic, Polar and Hydrogen Bonding Based Drug-Receptor Interaction of TetrahydroimidazobenzodiazepinonesV.K. Sahu, A.K.R. Khan, R.K. Singh, P.P. SinghAnti-HIV drug discovery has been increasingly focusing on HIV-1-RT (reverse transcriptase) as a potential therapeutic target. Tetrahydroimidazobenzodiazepinone (TIBO) belongs to non-nucleoside group of reverse transcriptase inhibitors (NNRTIs). A computational chemistry study has been performed on a series of tetrahydroimidazo-benzodiazepinones as HIV-1-NNRT inhibitors. Problem statement: In order to search out new drug of desired activity from the lead compounds, there was … …American Journal of Immunology, Vol. 4, Issue 3 · 30 Sep 2008 · 8,839 accessesView PDFCite
