Research ArticleOpen accessIn the abstractHardware Implementation of a Genetic Algorithm Based Canonical Singed Digit Multiplierless Fast Fourier Transform Processor for Multiband Orthogonal Frequency Division Multiplexing Ultra Wideband ApplicationsMahmud Benhamid, Masuri B. OthmanProblem statement: Ultra Wide Band (UWB) technology has attracted many researchers' attention due to its advantages and its great potential for future applications. The physical layer standard of Multi-band Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB system is defined by ECMA International. In this standard, the data sampling rate from the analog-to-digital converter to the physical layer is up to 528 … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficacy of Some Commercial Chemical Disinfectants on Salmonella enterica Serovar TyphimuriumEssam S. Soliman, E. G. Taha, M. A.A. Sobieh, P. G. ReddyProblem statement: Poultry industry is intensive and consistently applies an all-in, all-out system with the aim of minimizing infection pressure and targeting specific pathogens like Salmonella which remains one of the leading causes of food-borne illness, many questions regarding the introduction and persistence in animal production still remain. Therefore disinfection during production break is a routine part of the biosecurity … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow to Guide and Assess Risk Reduction using Risk Characterization IndicatorsPeter Borgen Sørensen, Rainer Brüggemann, Marianne Thomsen et al.Problem statement: The risk level predictions in risk assessment often suffer from uncertainties and may, thus, overlook some adverse effects. This problem can be reduced by using risk reduction strategies that continuously guide activities toward lowest possible risk. Approach: This study suggested a method to guide and assess such risk reduction strategies using multi-indicator risk characterization. It was a challenge … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison and Parametric Study of Flameless Oxidation in a Gas Turbine Using Two Kinetics MechanismsMohamed Hamdi, Hmaïed Benticha, Mohamed SassiThe so-called "Flameless Oxidation" is a novel combustion mode, in which combustion products are re-circulated and mixed into the fresh incoming fuel and air streams. This reduces the concentration of the reactants and thereby reducing the reaction rate through avoiding the formation of sharp high temperature zones in the combustion chamber. Flameless combustion has been acknowledged as one of the … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractBridging from Cells to Cognition in Autism Pathophysiology: Biological Pathways to Defective Brain Function and PlasticityMatthew P. Anderson, Brian S. Hooker, Martha R. HerbertWe review evidence to support a model where the disease process underlying autism may begin when an in utero or early postnatal environmental, infectious, seizure, or autoimmune insult triggers an immune response that increases reactive oxygen species (ROS) production in the brain that leads to DNA damage (nuclear and mitochondrial) and metabolic enzyme blockade and that these inflammatory and oxidative … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 17,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmunopathogenesis of Dengue Hemorrhagic FeverHuan-Yao Lei, Kao-Jean Huang, Yee-Shin Lin et al.Dengue virus infection causes Dengue Fever (DF), Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS) whose pathogeneses were not clearly understood. A new hypothesis of immunopathogenesis is proposed for the development of the DHF/DSS. An aberrant immune over-activation after dengue virus infection not only impair the immune response to clear the virus, but also result in overproduction of cytokines … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 14,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Biopterin Transporter (BT1) Gene on Growth and Infectivity of LeishmaniaManju Jain, Vandana S. Dole, Peter J. Myler et al.Leishmania are known to be auxotrophic for pteridines that are known to play a critical role in the parasites survival. In the present work the role of biopterin transporter in the growth of the parasite and infectivity in to macrophages has been worked out. The role of biopterin transporter in the susceptibility of Leishmania to antimonial compounds has also been … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 4 · 31 Dec 2007 · 7,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractCohesion Metrics for Ontology Design and ApplicationHaining Yao, Anthony M. Orme, Letha EtzkornRecently, domain specific ontology development has been driven by research on the Semantic Web. Ontologies have been suggested for use in many application areas targeted by the Semantic Web, such as dynamic web service composition and general web service matching. Fundamental characteristics of these ontologies must be determined in order to effectively make use of them: for example, Sirin, Hendler … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 149,288 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSex-Based and Age-Specific Trends in Gardnerella vaginalis Infection: An Epidemiological Study in Republic of Korea, 2018-2022Hyeok-Jin Kwon, Sun-Gyu Kim, Junmin Lee et al.Sexually Transmitted Infections (STIs) are an important global public health issue caused by various pathogens. STI symptoms can manifest at different times, depending on the sex, age, and infection route. Here, we aimed to assess the occurrence of STIs in the Republic of Korea, explore associated global trends, and identify pathogens with high positivity rates to inform future health policies. … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 29 Jan 2026 · 1,928 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMethamphetamine Inhibits β-Chemokines and Co-Stimulatory Molecule Expression by Dendritic CellsMadhavan P.N. Nair, Jose W. Rodriguez, Irina M. Borodowsky et al.The US is currently experiencing a serious epidemic of methamphetamine (Meth) use entangled with HIV-1 infection. Blood monocyte derived dendritic cells (DC ) are the first line of defense against HIV-1 infection and are the initial target of HIV-1 in injection drug users. Chemokines are known to be HIV-1 suppressing molecules and are positively associated with non- progression of HIV … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 6,543 accessesView PDFCite
