Research ArticleOpen accessIn the abstractBoundary Effect on Marangoni Convection in a Variable Viscosity Fluid LayerN.Z. Abidin, N.M. Arifin, M.S.M. NooraniThe onset of Marangoni convection in a horizontal fluid layer with a free surface overlying a solid layer heated from below is studied. Problem is focused on the effect of the solid layer depth or its conductivity. The viscosity group, Rv, Biot number, Bi, depth ratio, dr and conductivity ratio, kr, are significant on determining the critical Marangoni number Mc … …Journal of Mathematics and Statistics, Vol. 4, Issue 1 · 31 Mar 2008 · 6,915 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigations on the Grasping Contact Analysis of Biological Tissues With Applications in Minimally Invasive SurgeryAli Bonakdar, Javad Dargahi, Rama BhatAnalytical and finite element methods are employed to determine the contact pressure on the surface of a tissue being grasped by an endoscopic grasper, in Minimally Invasive Surgery (MIS). Normally, an endoscopic grasper is corrugated (teeth-like) in order to grasp slippery tissues. It is highly important to avoid damage to the tissues while grasping and manipulation during endoscopic surgery. Therefore, … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,905 accessesView PDFCite

Research ArticleOpen accessIn the abstractThermodynamics, Non-Linear Isotherms, Statistical Modeling and Optimization of Phosphorus Adsorption from WastewaterAkinpelu Kamoru BabayemiPalm Kernel Shell (PKN), an eco-friendly biomass, was carbonized and activated for the removal of phosphorus from wastewater through batch adsorption process. The studies evaluate the effects of pH, particle size, dosage and contact time on the adsorption capacity of the prepared adsorbent. The equilibrium concentration data and the amount of adsorption were described using non-linear regression analysis of the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 19 Nov 2016 · 7,512 accessesView PDFCite
HypothesisOpen accessIn the abstractNew Opportunities for Fullerenes and for GrapheneClive DelmonteThis is a conjecture which defines a new class of electrically conducting polymer that chemically confines metals, ions or clusters within an electric potential constraining them to react in ways novel to chemistry. The polymers are planar on a planar surface and adhere as a П-bonded electron sheet to planar, electron-delocalized surfaces as in Fullerenes, graphene (both sides) and graphite. … …Current Research in Nanotechnology, Vol. 6, Issue 2 · 1 Jan 2016 · 13,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction and Characterization of Bio-Char from the Pyrolysis of Empty Fruit BunchesMohamad Azri Sukiran, Loh Soh Kheang, Nasrin Abu Bakar, Choo Yuen MayProblem statement: The palm oil industry generates an abundance of oil palm biomass such as the Empty Fruit Bunch (EFB), shell, frond, trunk and Palm Oil Mill Effluent (POME). For 88 million tones of Fresh Fruit Bunch (FFB) processed in 2008, the amount of oil palm biomass was more than 26 million tones. Studies about production of bio-char from oil … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 9,811 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Earthquake Demolition Debris on the Quality of GroundwaterM. S. Benmenni, K. BenrachediProblem statement: Debris from construction or demolition/deconstruction processes have no significant impact on the environment as they are res-usable and inert. This has been also long admitted for solid waste generated by the demolition of damaged cities following violent earthquakes. Approach: This study is a contribution to the assessment of actual impact on the quality of groundwater of buried demolition … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Clay/Chitosan Bionanocomposites by UV-Irradiation MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver/Montmorillonite/Chitosan Bionanocomposites (Ag/MMT/Cts BNCs) have been synthesized by UV-irradiation reduction method in the absence of any reducing agent or heat treatment which is used to antibacterial application and medical devices. Approach: MMT, Chitosan and AgNO3 were used as a solid support, stabilizer and silver precursor, respectively. The properties of Ag/MMT/Cts BNCs were studied as a function of UV-irradiation … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 8,815 accessesView PDFCite
