Research ArticleOpen accessIn the abstractSupporting the Josephson Interpretation of Low Energy Nuclear Reactions and Stabilization of Nuclear WasteF. Osman, H. Hora, X. Z. Li et al.Brian Josephson appealed at the meeting of the Nobel Laureates July 2004 against the ignorance of physicist to the phenomenon of cold fusion. Though there are good reasons against many publications on this topic but not for all what was reported. It seems to be indicated to summarize the following serious, reproducible and confirmed observations on the reactions of protons … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,167 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 · 6,390 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of the Correcting Gains of Fractional Order Hold Devices for Inter-sample Output ReconstructionM. D.L. Sen, A. BilbaoThe design of Fractional Order Holds (FROH) of correcting gains β ∈ [-1, 1] (potentially and possibly including zero-order holds, ZOH with β = 0, and firelation holds, FROH relating) is discussed related to achieving output deviations being close with respect to its sampled values. A squared error time- integral between the current output and its sampled values is minimized … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpidemiological Models Applied to Viruses in Computer NetworksJos R.S. Piqueira, Betyna F. Navarro, Luiz H.A. MonteiroTo investigate the use of classical epidemiological models for studying computer virus propagation we described analogies between computer and population disease propagation using SIR (Susceptible-Infected-Removed) epidemiological models. By modifying these models with the introduction of anti-viral individuals we analyzed the stability of the disease free equilibrium points. Consequently, the basal virus reproduction rate gives some theoretical hints about how to … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,582 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Geosta Addition on Cement-stabilised Chicoco Mud of the Niger DeltaOlujide OmotoshoChicoco is a very soft and extremely compressible organic marine mud found extensively and to considerable depths within the saline tidal flat or mangrove swamp of the Niger delta in southern Nigeria. Natural chicoco is highly undesirable, barely able to support a human of average weight but air-dried chicoco has been used successfully by the indigeneous people for shore protection, … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrofluorimetric, Atomic Absorption Spectrometric and Spectrophotometric Determination of Some FluoroquinolonesHesham SalemSimple, accurate, sensitive and selective spectrofluorimetric, atomic absorption spectrometric and spectrophotometric methods are described for the quantitative determination of ten fluoroquinolones (amifloxacin, ciprofloxacin hydrochloride, difloxacin hydrochloride, enoxacin, enrofloxacin, lomefloxacin hydrochloride, levofloxacin, norfloxacin, ofloxacin and pefloxacin mesylate). The first method was a spectrofluorimetric method in which samples of the studied drugs in 0.1 N H2SO4 showed native fluorescence at 450 nm … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,320 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmission of Nitrogen Dioxide from Butane Gas Heaters and Stoves IndoorsMarwan Ghosn, Roula Flouty, Najat A. SalibaLevels of indoor nitrogen dioxide (NO2) in a home equipped with butane gas stove and heaters are reported between the months of February and July 2003. Diffusion passive sampling was used for the simultaneous measurements of indoor and outdoor NO2 concentrations. The overall average indoor NO2 concentrations were 15.6 and 22.3 μg m-3 for the living room and kitchen, respectively, … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 9,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtended IOWG Operator and its Use in Group Decision Making Based on Multiplicative Linguistic Preference RelationsZeshui XuIn [1], Xu and Da introduced the Induced Ordered Weighted Geometric (IOWG) operator, which takes as its argument pairs, called OWG pairs, in which one component is used to induce an ordering over the second components which are exact numerical values and then aggregated. In this study, we develop an extended IOWG (EIOWG) operator, in which the second components are … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,119 accessesView PDFCite
