Research ArticleOpen accessIn the abstractNUCLEAR DETONATION AROUND COMPACT OBJECTSC. Sivaram, Kenath Arun, O.V. KirenIn this study we explore the various aspects involved in nuclear detonations occurring around compact objects and the energetics involved. We discuss the possibility of sub-Chandrasekhar white dwarfs detonating due to the buildup of a layer of hydrogen on the CO white dwarf by accreting from a companion star to explain observed deviations such as subluminous type Ia. We also … …Physics International, Vol. 5, Issue 1 · 24 Mar 2014 · 8,229 accessesView PDFCite
Research ArticleOpen accessIn the abstractLagrangian Micromixing Models for Concentration Fluctuations: An OverviewPaolo Monti, Giovanni Leuzzi, Andrea AmicarelliThis study presents a brief overview of the main features, theoretical formulations and validation tests of some Lagrangian micromixing models, currently used for estimations of the ensemble mean and the turbulent fluctuations of concentration. Their application fields regards several pollutant dispersion phenomena such as: accidents (power or production plants, terroristic attacks, hydrocarbons storage and transport, extraordinary emissions), odours (power plants … …American Journal of Environmental Sciences, Vol. 8, Issue 6 · 28 Dec 2012 · 6,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractTheoretical Study of the Proton Transfer in EnaminonesRita Sabah EliasProblem statement: Hydrogen bonding has a vital rule to unrevealed the nature of many different interactions both in gas phase and condensed media thus it is one of the most important concepts in chemistry. Enaminoes with their ability to form intrahydrogen bonded cheated rings represent one of the suitable compounds to study such concept. Approach: The three possible tautomers of … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 23 Nov 2011 · 7,421 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Relation between Physiological Parameters and the Anxiety State in Competitive Men Handball Players During Official CompetitionsAlexandru Acsinte, Eftene Alexandru, Alexandru Păcuraru et al.Problem statement: The aim of this study was to examine the blood biochemical and physiological changes that occur during competitions in elite handball players-men in a specific kind of anxiety state. The grounding, elaboration, verification and evaluation of a scientific concept based on psychological, physiological and biochemical guidance of the effort in competitive handball in order to generalize it at … …Journal of Social Sciences, Vol. 7, Issue 3 · 16 Jul 2011 · 7,708 accessesView PDFCite
Research ArticleOpen accessIn the abstractNatural Sensitizer for Dye-Sensitized Solar Cells Using Three Layers of Photoelectrode Thin Films with a Schottky BarrierHo Chang, Mu-Jung Kao, Tien-Li Chen et al.Problem statement: This study combines Au nanoparticles with TiO2 nanoparticles to form a Schottky barrier and applies it to the photoelectrode thin film of Dye-Sensitized Solar cells (DSSCs). Approach: First, commercial TiO2 powder (Degussa P25) was put into the alkaline solution to prepare TiO nanotubes (Tnt) by a hydrothermal process. Tnt were sintered at 550° to obtain TntC550 particles and … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the abstractDifferential Gene Expression in Zebrafish (Danio rerio) Following Exposure to Gaseous Diffusion Plant Effluent and Effluent Receiving Stream WaterBen F. Brammell, Andrew J. WiggintonProblem statement: The expression of six genes known to serve as bioindicators of environmental stress were examined using real-time quantitative PCR in liver tissue extracted from zebrafish (Danio rerio, Hamilton) exposed to effluent and effluent containing stream water associated with the Paducah Gaseous Diffusion Plant (PGDP). Approach: The PGDP, the only active uranium enrichment facility in the US, is located … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,775 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 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 abstractOzone Treatment of Animal Manure for Odor ControlFahad Nasser AlkoaikProblem statement: The effectiveness of ozone in reducing odor emission from liquid animal manure was evaluated under batch and continuous treatment operations.
