Research ArticleOpen accessIn the abstractCD2 Shown to Facilitate CD4+ Cell Differentiation during Visceral Leishmaniasis, a Receptor Based StudySukrat Sinha, Shanthy Sundaram, Sanjiva Bimal et al.This study addressed the role of CD2 on CD4+ T helper cells in relation to the TCRVα1 and CD70 in two groups of BALB/c mice viz control and infected (1×107 L. donovani promastigotes). The results showed with the downregulation of CD2 expression there is a pronounced decrease of TCRVα1 and CD70 on CD4+ cells in mice. An insight into the … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 28 Nov 2015 · 7,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractE-loyalty and Business to Business (B2B) E-Commerce Success: Applied Study on Sample of E-Retailers in Amman City, JordanAhed Al-Haraizah, Baha`a Al-NadyThis research paper investigates the antecedents and consequences of customer loyalty in an online business-to-business e-commerce context. Moreover, this research identifies two key factors of e-loyalty (attitudinal and behavioral loyalty) that potentially impact business to business e-commerce success within e-retailers in Amman city. Therefore, the aim of this research paper is to develop a comprehensive research model utilized for discovering … …American Journal of Economics and Business Administration, Vol. 7, Issue 3 · 2 Sep 2015 · 7,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractModel of Adsorption on Epitaxial Single-Layer GrapheneDavydov Sergei, Lebedev AlexanderModel of adsorption on graphene is built by two steps: For the beginning density of states for the graphene monolayer on solid substrate is calculated, then adsorbed atom is placed on the such constructed epitaxial graphene. Both metallic and semiconducting substrates are considered. Charge transfer between adatom and epitaxial graphene is estimated. Effects of graphene layer and substrate on the … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 13 Jul 2015 · 5,982 accessesView PDFCite
Research ArticleOpen accessIn the abstractProcess Intensification for Production and Recovery of Biological ProductsHamideh Vaghari, Maryam Eskandari, Vahideh Sobhani et al.Bioprocesses are important biological reactions which need several sophisticated methods and equipment to produce many novel and important compounds which some of them are traditionally produced by synthetic chemical reactions. In bioprocesses, the products are often produced in a dilute environment and finally they require a high purity. Because of that, downstream processes are usually included a large number of … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 29 Jan 2015 · 8,124 accessesView PDFCite
Research ArticleOpen accessIn the abstractCLASSIFICATION OF MICROCALCIFICATION BASED ON WAVE ATOM TRANSFORMA. Rajesh, Mohan EllappanBreast cancer is a serious problem for women in the world. It is the most common form of cancer diagnosed in woman, with one in nine women expected to be diagnosed with some form of cancer in their life-time. It is second only to lung cancer in cancer related deaths. Statistics shows that the case of breast cancer in the … …Journal of Computer Science, Vol. 10, Issue 8 · 5 Apr 2014 · 6,517 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE USE OF DIFFERENT LEVELS OF MULTI-ROOM MODELING APPROACH-APPLICATION TO BUILDING POLLUTION TRANSPORT AND EFFICIENCY OF OFF-HOUR VENTILATIONAhmed Cherif MegriSeveral building simulation programs have been developed for design, analysis and prediction of the distribution of temperature, airflow and heat transfer between inside and outside of a building and/or between different zones of the same building. These programs are categorized as mono-zone models, multi-room models, zonal models, Computational Fluid Dynamics (CFD) models and multi-zone models. The number of computer programs … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 25 Mar 2014 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractSHAPE RETRIEVAL THROUGH MAHALANOBIS DISTANCE WITH SHORTEST AUGMENTING PATH ALGORITHMS. Muruganathan, N. Devarajan, D. Chitra, T. ManigandanShape matching and object recognition plays an vital role in the computer vision. The shape matching is difficult in case of the real world images like mpeg database images since the real world images has the internal and external contours. The Mahalanobis distance based shape context approach is proposed to measure similarity between shapes and exploit it for shape retrieval. … …Journal of Computer Science, Vol. 10, Issue 4 · 3 Dec 2013 · 6,856 accessesView PDFCite
Research ArticleOpen accessIn the abstractACKA 500 WATT POWER AMPLIFIER FOR A 144 MHZ CHANNEL BASED ON A VHF PUSH-PULL POWER MOS TRANSISTORAgus Harjoko, Tri Wahyu SupardiIn a wireless communication, a signal power amplifier is needed to carry signals over a long distance. Many signal amplifiers are made of tube as the amplifying component and as such they suffer low efficiency. This study presents results of the research on designing and implementing solid state 144MHz signal amplifier employing MOSFET BLF278 as the active component of the … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 7,615 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnumeration of Microbes and Gas Production During Denitrification and Nitrogen Fixation Processes in SoilA. E. Ghaly, K. N. MacDonaldDry plant material contains 2-4% nitrogen, making it an essential nutrient for all plants. The nitrogen cycle regulates the pathways which transform nitrogen from a relatively inert dinitrogen gas to forms of organic nitrogen such as proteins and nucleic acids. Denitrification and nitrogen fixation are the two most important processes that remove and add nitrogen to the soil, respectively. The … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 3 · 11 Sep 2012 · 8,618 accessesView PDFCite
Research ArticleOpen accessIn the abstractSymbol Timing Estimation in Multiband Orthogonal Frequency Division Multiplexing based Ultrawide band SystemM. N. Suresh, S. J. Thiruvengadam, V. AbhaikumarProblem statement: The Multiband Orthogonal Frequency Division Multiplexing (MB-OFDM) Based Ultra Wideband system (UWB) is highly susceptible to symbol timing error. Symbol timing estimation in MB-OFDM based UWB is difficult due to the presence of strongest path at delayed instant. Approach: Symbol timing estimation has two steps namely a coarse estimation and a fine estimation. In this study, a maximum … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 10 Feb 2012 · 7,101 accessesView PDFCite
