Research ArticleOpen accessIn the abstractLarge Eddy Simulation of an Ammonia JetM. Salinas-Vazquez, A. Espinosa, E. Barrios, W. VicenteA compressible jet flow of ammonia was studied through a series of Large Eddy Simulations. Simulations were focused in the zone where the inertial effects are much bigger than the gravitational ones. The ammonia jet is discharged into an air medium and the gases are treated as a two non-reactive ideal gas mixture. Different simulations were performed, going from the … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Chemical Admixtures on the Engineering Properties of Tropical Peat SoilsBujang B.K. Huat, Thamer A. Mohamed, Shukri MaailThis research describes a study on the effect of chemical (cement and lime) admixtures on the index and engineering properties (compaction and unconfined strength) of tropical peat soils. The ordinary Portland cement and hydrated lime were used. The amounts cement and lime added to the peat soil sample, as a percentage of the dry soil mass was in the range … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 8,472 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Information Technology for Good Governance and SocietyHasan Al-ShalabiFor developing countries, Technology is considered to be a lever for development. The development of Information Technology (IT) has a wide potential in all aspects of the societal development. Especially, for any developing country, IT has brought an overall change and growth. The developing countries need to focus on 6Cs of IT i.e. Computer density, Communication, Connectivity, Cyber laws, Cost … …Journal of Social Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 9,875 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Chord Length Distribution Along an Edge: The Wedge Case and the Quadratic Rod CaseWilfried GilleThe analytic expression is given for the chord length distribution density f(l,b) along the edge of an infinitely long rectangular wedge and for a quadratic rod, both of constant breadth b. The general result is: A constant behaviour for 0 < l < b and a finite jump of size 2/b at l = b is an intrinsic feature of … …Journal of Mathematics and Statistics, Vol. 1, Issue 2 · 30 Jun 2005 · 6,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractDisplacement of Boron from the Silicon Crystal Nodes by Interstitial Si Atoms During Implantation and AnnealingM. Jadan, A. R. Chelyadinskii, V. Y. YavidThe process of boron displacement from the nodes into interstitial positions of interstitial Si atoms in silicon (Watkins effect) on the conditions of implantation and annealing has been investigated with the help of X-ray diffraction and electrical methods. It was revealed that the efficiency of the Watkins substitution is determined by the ion current density (level of ionization). With increasing … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Multivariate Order Statistics by Marginal Ordering of i.n.n.i.d. Random Vectors Under Discontinuous d.f.'sM. Güngör, A. Gökhan, Y. BulutIn this study, the joint Probability Density Function (p.d.f.) of multivariate order statistics by marginal ordering of the Independent and Not Necessarily Identically Distributed (i.n.n.i.d.) random vectors under discontinuous d.f.'s is examined. Furthermore, the continuous cases are derived from the discontinuous cases. …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,345 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation of Landscape Metrics to Surface Water Biology in the Savannah River BasinMaliha S. Nash, Deborah J. Chaloud, Susan E. FransonSurface water quality for the Savannah River basin was assessed using water biology and landscape metrics. Two multivariate analyses, partial least square and canonical correlation, were used to describe how the structural variation in landscape metrics may affect surface water biology and to define the key landscape variable(s) that contribute the most to variation in surface water quality. The results … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractChord Length Distributions of the HemisphereWilfried GilleThe distribution laws for two types of isotropic uniform random chords of the hemisphere, cap-chords and basic-chords, are investigated separately. From both distribution densities, the chord length distribution density of the whole hemisphere is derived. …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,361 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteraction of a C-terminal Truncated Hepatitis C Virus Core Protein with Plasmid DNA Vaccine Leads to in vitro Assembly of Heterogeneous Virus-like ParticlesNelson Acosta-Rivero, Joanna Poutou, Alexis Mussachio et al.Recently, it has been shown that HCV core proteins (HCcAg) with C-terminal deletions assemble in vitro into virus-like particles (VLPs) in the presence of structured RNA molecules. Results presented in this work showed that a truncated HCcAg variant covering the first 120 aa (HCcAg.120) with a 32 aa N-terminal fusion peptide (6xHistag-XpressTMepitope) interacts with plasmid DNA vaccine. Interestingly, the buoyant … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,754 accessesView PDFCite
