Research ArticleOpen accessIn the abstractFabric Behavior of Sand in Post-liquefactionSeyed Amirodin SadrnejadAn anisotropic plasticity model for post-liquefaction of the undrained behavior of sand is presented. The model incorporates the critical/steady state concept that postulates the existence of a state where sand continuously deforms at a certain constant effective stress depending two main parameters of both initial bulk parameters (void ratio or relative density) and the stress level (mean stress). The local … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,409 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Pulverised Fly Ash (PFA) as an Ameliorant of Lead Contaminated SoilsEdmond Gatima, Mwinyikione Mwinyihija, Ken KillhamFly Ash (FA) is obtained by electrostatic or mechanical precipitation of dust-like particles from the flue gases of furnace fired with coal or lignite at 1100 to 1400°C. About 95-99% of Fly Ash consists of oxides of Si, Al, Fe and Ca, about 0.5 to 3.5% consists of Na, P, K and S and the remainder is composed of trace … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,014 accessesView PDFCite

Silver nanoparticles remain to be potentialantifungal, antibacterial, anti-inflammatory, and antiviral agents. Further, itis demonstrated that silver nanoparticles have been involved in arresting thegrowth of several bacterial species thereby reducing their harmful effects.Micro-organisms are being … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 5 Sep 2022 · 5,870 accessesView PDFCite
Research NotesOpen accessAll words, across the recordTurbulent-Fluid-Based Simulation of Dynamic Liquefaction Using Large Deformation Analysis of Solid PhaseRohollah TaslimianTo accurately simulate the cyclic liquefaction phenomenon, it is necessary to establish a well-defined coupling between the solid particles and the high-velocity percolating pore fluid. For this purpose, the existing literature extensively examines large deformation liquefaction analyses for the solid phase, regardless of the fluid flow nonlinearity. On the other hand, the transient fluid pressure gradient governed by the turbulence … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 22 Feb 2024 · 6,015 accessesView PDFCite
