Research ArticleOpen accessIn the abstractSimulation of the Pedestrians' Influence to the Capacity of Motorised Vehicles in a RoundaboutT. Tollazzi, T. Lerher, M. ŠramlA new approach is suggested for dimensioning roundabouts with mathematical modeling of traffic flows using the discreet simulation method, and considering the statistically evaluated entry data for vehicles’ and pedestrians’ traffic flows. The simulation results are useful when determining the capacity of the roundabouts, which will function in different circumstances. The presented model derives from the expected time void in … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome P-RAM Algorithms for Sparse Linear SystemsRakesh Kumar Katare, N.S. ChaudhariPRAM algorithms for Symmetric Gaussian elimination is presented. We showed actual testing operations that will be performed during Symmetric Gaussian elimination, which caused symbolic factorization to occur for sparse linear systems. The array pattern of processing elements (PE) in row major order for the specialized sparse matrix in formulated. We showed that the access function in2+jn+k contains topological properties. We … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 6,974 accessesView PDFCite
Research ArticleOpen accessIn the abstractCo-expression of Apoptosis-Related Molecules on Activated CD8+ CD38+ T-cells is Associated with HIV-1 Disease ProgressionJosé W. Rodríguez, Luis A. Rodríguez, Griselle Font et al.CD8+ T cells play a major role in controlling HIV-1 infection through the release of soluble lytic and non-lytic antiviral factors. Their decrease or defective function contributes to the HIV-1 disease progression. HIV-1 disease progression has been associated with a remarkable increase of CD38 expression on CD8+ T-cells. It has been also documented that a significant distribution of HIV-specific CD8+T-cells … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,016 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsymptotic Behavior for Solution of Reaction-Diffusion SystemsM. Yahi, K. SaoudiThe existence, uniqueness, and asymptotic behavior of the solution of a balanced two-component reaction-diffusion system have been investigated. It was shown that a global and unique solution existed and its second component can be estimated using the Lyapunov Functional. It was, also, demonstrated that each component of the solution converged, at infinity, to a constant which can be found in … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,849 accessesView PDFCite
Research ArticleOpen accessIn the abstractQualitative Ferromagnetic Hysteresis ModelingM. Mordjaoui, M. Chabane, B. Boudjema, R. DairaIn determining the electromagnetic properties of magnetic materials, hysteresis modeling is of high importance. Many models are available to investigate those characteristics but they tend to be complex and difficult to implement. A new qualitative hysteresis model for ferromagnetic core presented, based on the function approximation capabilities of adaptive neuro-fuzzy inference system (ANFIS). The proposed ANFIS model combined the neural … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 7,080 accessesView PDFCite
Research ArticleOpen accessIn the abstractHIV-1-Specific CTL Recognizing a Scarce Epitope Are Not Suppressed by HIV-1 Protease InhibitorsOtto O. YangHIV-1-protease inhibitors have received growing attention as agents that can affect proteases in human proteasomes, with potentially deleterious effects for HIV-1-specific cellular immunity. Studying the antiviral activity of HIV-1-specific CTL that recognize an epitope that is presented at limiting concentrations on infected cells, we find that several HIV-1 protease inhibitors do not affect their function. These data indicate that these … …American Journal of Immunology, Vol. 3, Issue 1 · 30 Jun 2007 · 7,019 accessesView PDFCite
Research ArticleOpen accessIn the abstractBeta-2-Microglobulin in Autism Spectrum DisordersPaula Goines, Joseph Schauer, Luke Heuer et al.Autism spectrum disorders (ASD) are heterogeneous neurodevelopmental diseases of unknown etiology. There are no biological markers for ASD and current diagnosis is based on behavioral criteria. Recent data has shown that MHC I, a compound involved in adaptive immune function, is also involved in neurodevelopment, synaptic plasticity and behavior. It has been suggested that altered MHC I expression could play … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractBounds Testing Approach to Cointegration: An Examination of Foreign Direct Investment Trade and Growth RelationshipsOteng Abayie Eric Fosu, Frimpong Joseph MagnusThis study examines the long-run impact of foreign direct investment and trade on economic growth in Ghana. Using an augmented aggregate production function (APF) growth model, we apply the bounds testing (ARDL) approach to cointegration which is more appropriate for estimation in small sample studies. The data span for the study is from 1970 to 2002. We found cointegration relations … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 9,336 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of A New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part I: Design of the Detection System and ApplicationsEric Carnes, Ebtisam WilkinsA portable, flow-through amperometric immunoassay system utilizing a newly designed immunosensor has been developed for the detection of bacteria. A sandwich scheme of immunoassay involving two stages of immunoreaction was employed using Escherichia coli as a model. E. coli antibodies were immobilized on Toray carbon paper to create a disposable immunofiltration membrane. Detection of the bacteria was achieved through the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2006 · 6,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow Serious Regional Economic Inequality in Jordan? Evidence from Two National Household SurveysMohammed Issa ShahateetThe objective of this study is to measure and explain the extent of regional economic inequalities in Jordan. To do so, this study uses the raw data of two national household surveys on expenditure and income that covers 5,971 and 11,153 households in 1997 and 2002, respectively. As a check on the empirical results, the study applies four measures of … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 7,216 accessesView PDFCite
