Research ArticleOpen accessIn the abstractVariable Velocity Influence on the Vibration of Simply Supported Bernoulli - Euler Beam Under Exponentially Varying Magnitude Moving LoadT. O. AwodolaThe variable velocity influence on the vibration of a simply supported Bernoulli-Euler beam, resting on a uniform foundation, under the action of an exponentially varying magnitude load moving with variable velocity is investigated in this work. The technique is based on the Finite Fourier Sine transformation and the Finite Difference method. Numerical results in plotted curves are presented. It is … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 7,659 accessesView PDFCite
Research ArticleOpen accessIn the abstractTurbo-coding of Coherence Multiplexed Optical PPM CDMA System With Balanced DetectionK. Chitra, V.C. RavichandranThe effects of turbo-coding on the coherence multiplexed optical PPM CDMA systems are shown by evaluating bit error rate (BER) with respect to system parameters such as interleaver length (K), number of simultaneous users (N), code length (f), initial pulsewidth (t0) and normalized threshold (θ) by including the effects of thermal noise and shot noise. Turbo-codes increase the number of … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,617 accessesView PDFCite
Research ArticleOpen accessIn the abstractInternalizing Versus Non-internalizing Receptors for Targeting L-Methioninase to Cancer CellsXiao-Ping Zang, Naveen R. Palwai, J. T. Pento, Roger G. HarrisonWe reported previously that L-methioninase targeted to the urokinase receptor of MCF-7 breast cancer cells is significantly more effective in inhibiting cell proliferation and migration than free L-methioninase both in vitro and in vivo. L-methioninase was targeted by linking at its amino terminus to an amino-terminal fragment (ATF) of urokinase. The ATF was selected for targeting because is has previously … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 3 · 30 Sep 2006 · 7,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of North America Free Trade Agreement on Mexican Environmental Policy (1994-2004)Ningu J. Kenneth, Jorge Torres Jácome, Sonia E.S. Gomez, Pérez ÁvilesThe scope of this study was to analyze the implementation of the environmental policy and the way Mexico has integrated the environmental aspects into a North America Free Trade Agreement (NAFTA). We are aware of the fact that many environmental costs do not necessarily reflect the environmental damage. Environmental costs are often defined by determining either the willingness of the … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 6,357 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis of Zeolite from Aluminium Etching By-Product: the Effect of Reaction Temperature on Crystallinity and Its CO2 Adsorption PropertyKanokorn Hussaro, Supaporn Douglas, Noppadon CheamsawatThe synthesis of zeolite from the by-product of aluminium etching process was investigated. The starting by-product reactant had high aluminium content, 92.17% wt. as Al2O3. Si and Na compositions were adjusted by the addition of sodium metasilicate, in the hydrogel process.The reaction time was fixed at 1 h., while the stirring speed was controlled at 200 rpm. and the temperature … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,524 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDynamic Measurement of Copper (II) Ion Adsorption in Activated Carbon Fixed Bed ColumnsTanokkorn Banjonglaiad, Eric Croiset, Peter Silveston et al.Dynamic experiments were carried out on the adsorption of copper (II) ions in a laboratory packed bed of activated carbon. Both pulse and step change inputs were used. Measurements were reproducible and replicate measurements furnished nearly identical parameters for a heterogeneous model of the activated carbon bed assuming Langmuir adsorption isotherm. The initial concentration of copper (II) ion was 3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,862 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Multi-Criteria Optimization Approach to Cam Curve Design Combining Different Splines Given by Fixed and Adjustable CheckpointsLéo Moussafir, Vigen ArakelianThis study proposes a multi-criteria design optimization of cam mechanisms. This approach is based on the multistage interconnection of different tools: MATLAB, ADAMS, and mode frontier. It consists of three main issues: (i) The polynomial representation of splines given by checkpoints defining the specific motion of the follower; (ii) The connection of these splines by different degrees of fitting in … …Journal of Mechatronics and Robotics, Vol. 7, Issue 1 · 24 Mar 2023 · 6,646 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExperimental Investigate the Effect of Burner Geometry on the Operation Window of the BurnerJameel Al-Naffakh, Mohammed Al-Fahham, Qahtan A. AbedThe purpose of this paper is to conduct an experimental study of a swirl burner with different lengths for a fixed diameter. Three models of rim length (5 cm, 10 cm and 15 cm) were taken. The results show that any change in the ratio of length to diameter will affect the flame position and structure of the downstream. It … …Energy Research Journal, Vol. 10, Issue 1 · 30 Oct 2019 · 7,428 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Effect of Bone Properties due to Skeletal Diseases on Stability of Cementless Hip StemsMohammed Rafiq Abdul Kadir, Nazri KamsahProblem statement: There are two types of implant fixation in hip joint replacement-cemented and cementless. The cemented types are, in general, more popular due to concerns of possible inability of cementless implants achieving maximum primary stability for bone integration. The concern is more significant in cases where there are major losses of cancellous bone stock and thinning of the trabeculae … …American Journal of Applied Sciences, Vol. 6, Issue 12 · 31 Dec 2009 · 7,169 accessesView PDFCite
