Research ArticleOpen accessIn the abstractDirect Analysis of Six Pharmaceuticals using Online Solid Phase Extraction Liquid ChromatographySiti Norbayu Mohd Subari, Rozita Osman, Norashikin SaimIn this study, three parameters (sample volume, cleanup and elution step) in large volume injection online Solid Phase Extraction Liquid Chromatography with diode array detection (SPE-LC) were optimized for the determination of six pharmaceuticals in wastewater samples. Preconcentration and separation were carried out using 2 columns, Dionex Ion Pac AG14A and Acclaim Polar Advantage II. Response Surface Methodology (RSM) was … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 31 Mar 2017 · 7,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpdating Italian Design Guide CNR DT-205/2007 in View of Recent Research Findings: Requirements for Pultruded FRP ProfilesFabio Minghini, Nerio Tullini, Francesco AscioneA discussion on some design rules for pultruded fiber-reinforced plastic (PFRP) profiles reported by guideline CNR DT-205/2007 from National Research Council of Italy is presented in the paper. At eight years after approval of this technical document, several changes and improvements are required following recent research findings and supplemental design rules should be incorporated into a future revision. The general … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 9,114 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Objective Optimization of FRP Jackets for Improving the Seismic Response of Reinforced Concrete FramesCorrado Chisari, Chiara BedonIn this study, a multi-objective Genetic Algorithm (GA) optimization procedure is proposed for the seismic retrofitting of Reinforced Concrete (RC) building frames via Fiber-Reinforced Polymer (FRP) jackets. The optimization problem is solved via numerically efficient but accurate Finite-Element (FE) models able to take into account the strengthening and ductility increase contribution for a given FRP jacketing configuration. Based on a … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeismic Assessment of Non-Seismically Designed Reinforced Concrete Frames with Core WallsTaek-Hyun Lee, Ki-Bong Choi, Taher Abu-LebdehThis study examines the seismic performance of four non-seismically designed reinforced concrete structures with core walls and proposes proper rehabilitation methods. The structures were selected based on the height of the structures, occupancy levels and floor plans. The seismic assessment results were compared based on the performance of the structures before rehabilitation and after rehabilitation. The results indicate that most … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 13 Dec 2014 · 6,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEW CONSTRUCTION METHOD OF RECTANGULAR PARTIALLY BALANCED INCOMPLETE BLOCK DESIGNS AND SINGULAR GROUP DIVISIBLE DESIGNSRezgui Imane, Z. Gheribi-AoulmiIn this study, we propose a new method of construction of rectangular Partially Balanced Incomplete Block (PBIB) designs of size k = 2s and 2≤s < l and singular Group Divisible (GD) designs of size k = 2l, l is the number of columns in a rectangular matrix containing v = n × l treatments. We give the parameters expression … …Journal of Mathematics and Statistics, Vol. 10, Issue 1 · 9 Jan 2014 · 9,233 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadiation and Thermal Effects in Experimental High Dense Metal Fuel Elements for Advanced LMFRGolovchenko YulianKnown disadvantages of high-dense α-U metal fuel (intense radiation growth and radiation swelling, poor compatibility with steel claddings) can be reduced to the minimum by "constructive" approaches based on mechanical restraint of radiation growth and swelling and also on application of protective layers on fuel columns and claddings. Effectiveness of these methods has been confirmed during irradiation of full-sized fuel … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 7,022 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Link Dimensions on D Type Eccentric Steel FramesMazen Ali MusmarIn seismic prone regions, buildings are designed to maintain sufficient stiffness during moderate earthquakes and to absorb and dissipate a large amount of the energy released due to severe earthquakes. The usual steel framing systems; the moment frames require larger member sections to satisfy stiffness requirements and have large ductility capacity, the concentrically braced frames satisfy stiffness on the expense … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 12 Feb 2013 · 7,529 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearches Concerning the using of Moven© Inertial Navigation System in Monitoring the Male Triple Jump EventMihilescu Liliana, Mihai Ilie, Bidiugan RaduProblem statement: This study aims to highlight ways of using Moven© inertial navigation system applied in the monitoring of the male triple jump event technique. Inertial navigation system involves the use of some elements to determine the coordinates and speed of a body by processing information related to its acceleration. Approach: The research results point out that this equipment can … …Journal of Social Sciences, Vol. 7, Issue 3 · 16 Jul 2011 · 7,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign For Test Technique for Leakage Power Reduction in Nanoscale Static Random Access MemoryN. M. Sivamangai, GunavathiProblem statement: As technology scales down, the integration density of transistors increases and most of the power is dissipated as leakage. Leakage power reduction is achieved in Static Random Access Memory (SRAM) cells by increasing the source voltage (source biasing) of the SRAM array. Another promising issue in nanoscaled devices is the process parameter variations. Due to these variations, higher … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,505 accessesView PDFCite
