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
Research ArticleOpen accessIn the abstractAntibiogram-Derived Radial Decision Trees: An Innovative Approach to Susceptibility Data DisplayRocco J. Perla, Paul P. BelliveauHospital antibiograms (ABGMs) are often presented in the form of large 2-factor (single organism vs. single antimicrobial) tables. Presenting susceptibility data in this fashion, although of value, does have limitations relative to drug resistant subpopulations. As the crisis of antimicrobial drug-resistance continues to escalate globally, clinicians need (1) to have access to susceptibility data that, for isolates resistant to first-line … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Transparent Conductive Thin Films of In 2O 3:Sn by Spray Pyrolysis TechniqueSeyed Mohammad Rozati, Tohid GanjHighly conductive transparent In2O3:Sn (ITO) thin films were prepared onto glass substrate using the spray pyrolysis technique. It is observed that these films are polycrystalline with the preferred orientation of [400]. The extent of this orientation increases with substrate temperature. The results show that films with a sheet resistance as low as 35Ω/cm2 and with a transmittance as high as … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,763 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreasing the Strength of Standard Involute Gear Teeth with Novel Circular Root Fillet DesignV. Spitas, Th. Costopoulos, C. SpitasIn this study the idea of spur gear teeth with circular instead of the standard trochoidal root fillet is introduced and investigated numerically using BEM. The strength of these new teeth is studied in comparison with the standard design by discretizing the tooth boundary using isoparametric Boundary Elements. In order to facilitate the analysis the teeth are treated as non-dimensional … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,586 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Laser Irradiation on the Structural and Electrical Properties of Co-Zn Ferrite Thin FilmNehad M. TashtoushThin films of irradiated and non-irradiated Co-Zn ferrite was prepared by the thermal evaporation method on a glass substrate. The samples were annealed at 200°C, 400°C and 600°C for 1hr. The XRD analysis of all kinds of films, prepared for this study, shows that the spinel phase is almost completed after annealing. The change of the XRD after annealing is … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,033 accessesView PDFCite
Review ArticleOpen accessIn the abstractAbout Boeing X-32Relly Victoria Virgil PetrescuThe Boeing X-32 is a demonstration jet designed for the Joint Strike Fighter contest. He lost the Lockheed Martin X-35 demonstrator, which was further developed in the Lockheed Martin F-35 Lightning II. Boeing's competitive advantage has been to provide considerably lower costs of production and lifecycle by minimizing variations between different versions of the JSF. Therefore, the X-32 was designed … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 1 Apr 2019 · 9,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractForces of a 3R RobotRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.In this study, one presents a method for determination of kinetostatic parameters in dyad 3R. It starts with the determination of the forces in the joints: RB, RD, R23. To generalize the method including for the 2R robots, enter both the moments M1, M2. This module (2R) is the main module found in all rotating anthropomorphic robotic structures and similar … …Journal of Mechatronics and Robotics, Vol. 1, Issue 1 · 8 Nov 2017 · 7,738 accessesView PDFCite
