Research ArticleOpen accessIn the abstractAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,298 accessesView PDFCite

Research ArticleOpen accessIn the abstractAdsorption Study of Several Hydrophobic Organic Contaminants on an Aquifer MaterialBarbara Ruffino, Mariachiara ZanettiProblem statement: Aim of the present research was to determine coefficient of partition KD between soil and groundwater for five hydrophobic organic pollutants (benzene, chlorobenzene, trichloroethylene-TCE, perchloroethylene-PCE and toluene) in an Italian aquifer material characterized by a low organic carbon content (fOC = 0.00262) by means of laboratory batch tests. Initial aqueous concentrations (quite different among the five compounds) were … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,366 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgressive Content-Sensitive Data Retrieval in Sensor NetworksBo Yang, Manohar MareboyanaProblem statement: For a sensor network comprising autonomous and self-organizing data sources, efficient similarity-based search for semantic-rich resources (such as video data) has been considered as a challenging task due to the lack of infrastructures and the multiple limitations (such as band-width, storage and energy). While the past research discussed much on routing protocols for sensor networks, few works have … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 6,845 accessesView PDFCite

ALzaydienProblem statement: It is well documented that lead is one of contaminants of industrial wastewaters and its pollution exists in the wastewater of many industries. As a result, recent research has focused on the development of cost effective alternatives using various natural sources and industrial wastes. In this setting, the use of low-cost agricultural materials, waste and residues for recovering … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeep Defects Annihilation in GaAs1-xNx Layers by Si-dopingN. Ben Sedrine, A. Hamdouni, J. Rihani et al.The photoluminescence (PL) properties of Si-doped GaAs0.985N0.015 with different silicon content were investigated. The study was carried out on a set of three samples grown by Molecular Beam Epitaxy (MBE) on GaAs (001) oriented substrate using a radio frequency nitrogen beam source. For all samples, the PL measurements show the presence of a wide band situated at 0.83 eV which … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 30 Apr 2007 · 8,160 accessesView PDFCite
Research ArticleOpen accessIn the abstractDifferent Methods for Pion-nucleus Optical PotentialS. A.E. Khallaf, A. A. IbrahimElastic and inelastic cross-sections for pion scattering on 12C at pion kinetic energy ranging from 50 to 260 MeV are computed using three independent methods of π± -nucleus optical potential, the 3α-particle model of the nucleus, the equivalent local Kisslinger potential and the Laplacian one. Reasonable fits to the measured values are obtained for 12C without adjusting free parameters. The … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,387 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,775 accessesView PDFCite
