Research ArticleOpen accessIn the abstractEvaluation of Liquefaction Return Period for Bangalore Based on Standard Penetration Test Data: Performance Based ApproachK. S. Vipin, T. G. SitharamProblem statement: The conventional liquefaction evaluation is based on a deterministic approach. However in this method the uncertainty in the earthquake loading is not properly taken into account. However recent research in this field indicates that this uncertainty in the earthquake loading has to be considered in the liquefaction potential evaluation. Moreover the evaluation of liquefaction return period is not … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,741 accessesView PDFCite

Research ArticleOpen accessIn the abstractImpedance Method Application for Multi-Layer Structure TestingMonzer Moh’D KrishanMulti-layer materials and structures are widely used in the modern aircraft industry. The main defect of these structures is delamination. The most appropriate method for detection of such kind flaws is the impedance testing method. This research is devoted to the features of the impedance method for multi-layer panel testing. The theoretical and experimental investigations of mechanical impedance are presented … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,282 accessesView PDFCite

Research ArticleOpen accessIn the abstractAn Operator Defined by Convolution Involving the Polylogarithms FunctionsK. Al Shaqsi, M. DarusWe define an operator on the class A of analytic functions in the unit disk U = {z :|z | < 1} involving the polylogarithms functions and introduce certain new subclasses of A using this operator. Some inclusion results, covering theorem, coefficients inequalities, and several other interesting properties of these classes are obtained. …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 7,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractWhat Accounts for Growth in African AgricultureGuy B. Nkamleu, Kalilou Sylla, Abdoulaye ZononEmpirical relationships between the rates of growth and total factor productivity growth, physical input accumulation, as well as institutional and agro-ecological change is evaluated using an international panel data set on 26 African countries and covering the period 1970-2000. The analysis employs the broader framework provided by empirical growth literature and recent developments in TFP measurement. Results suggest a positive … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrastructural and Immunological Characterization of Hepatitis C Core Protein-DNA Plasmid ComplexesNelson Acosta-Rivero, Yaraima Aguilera, Viviana Falcon et al.Recently, it has been shown that a truncated HCV core (HCcAg) variant, covering the first 120 aa (HCcAg.120), interacts with plasmid DNA vaccine (pIDKE2), encoding the HCV structural proteins (HCcAg, E1 and E2). In the present work, HCcAg.120-pIDKE2 complexes, forming heterogeneous packaged structures, were visualized using a negative stain/rotary shadow technique. Interestingly, 72 hours after intramuscular injection of HCcAg.120-pIDKE2 complexes … …American Journal of Immunology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,743 accessesView PDFCite

Research ArticleOpen accessIn the abstractA New Architecture for Improving Location Management in PCS NetworksHaidar Safa, Samuel PierreThis study proposes a new architecture for improving the location management in PCS networks. The proposed architecture employs several HLRs as opposed to one HLR in the IS-41 and GSM models. Indeed, the new architecture associates with each MU two types of HLRs ; a resident HLR that serves the location areas in which the MU often resides and a … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,781 accessesView PDFCite
