Research ArticleOpen accessIn the abstractA Study of Residual Oils Recovered from Spent Bleaching Earth: Their Characteristics and ApplicationsLoh Soh Kheang, Cheng Sit Foon, Choo Yuen May, Ma Ah NganThis study described the extraction of residual oils of spent bleaching earth (SBE) from palm oil refining industry, the properties and applications of residual oils obtained there from. Residual oils of SBE (acid-activated, WAC and neutral, NC) were recovered via solvent and supercritical-fluid (SC-CO2) extraction. The yields of residual oils recovered from WAC were higher than those from NC using … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 9,235 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrofluorimetric Study of the Charge-transfer Complexation of Certain Fluoroquinolones with 2,3,5,6-tetrafluoro-p-bezoquinoneD. Geffken, H. SalemA highly sensitive spectrofluorimetric method was developed for the first time, for the analysis of ten fluoroquinolones (FQs) antibacterials, namely amifloxacin (AMI), ciprofloxacin (CIP), difloxacin (DIF), enoxacin (ENO), enrofloxacin (ENR), lomefloxacin (LOM), levofloxacin (LEV), norfloxacin (NOR), ofloxacin (OFL) and pefloxacin (PEF) in their pharmaceutical dosage forms or in biological fluids through charge transfer (CT) complex formation with fluoranil (TFQ). The … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 6,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 2-Dimensional Model for the Transmission Dynamics of Schistosomiasis in the Human-Snail HostsG. Besigye-BafakiThe modes of transmission of schistosomiasis are considered. The transmission model is developed with an aim of establishing possible endemic equilibria within the community. Analysis of the model reveals that if the recovery rate β of human infectives and the death rate of snails δ are increased and if at the same time the contact rate κ of the human … …American Journal of Applied Sciences, Vol. 3, Issue 5 · 31 May 2006 · 6,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Control for Self-erecting Inverted Pendulum Via Adaptive Neuro-fuzzy Inference SystemA. A. Saifizul, Z. Zainon, N. A.Abu Osman et al.A self-erecting single inverted pendulum (SESIP) is one of typical nonlinear systems. The control scheme running the SESIP consists of two main control loops. Namely, these control loops are swing-up controller and stabilization controller. A swing-up controller of an inverted pendulum system must actuate the pendulum from the stable position. While a stabilization controller must stand the pendulum in the … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,326 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Some Stability Results for Fixed Point Iteration ProcedureM. O. Olatinwo, O. O. Owojori, C. O. ImoruIn this study, we establish that both the Mann and Ishikawa iteration processes are T-stable for the mappings T satisfying a more general contractive definition than that of Osilike[1] . The results obtained generalize some of the recent results of Osilike[1] which are themselves generalizations and extensions of some of the results of Harder and Hicks[2] and Rhoades[3,4]. …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 7,042 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Murine Charged Multivesicular Body Protein 2A, CHMP2A Interacts with the 5' and 3' Terminal Regions of Dengue Virus Complementary Minus-strand RNASuchita Chaudhry, Sathyamangalam Swaminathan, Navin KhannaDengue (DEN) viruses, of which there are four distinct serotypes (DEN-1, -2, -3 and –4), belong to the Flaviviridae family. Their ‘plus’ sense RNA genomes contain Non-Translated Regions (NTRs) at their 5’ and 3’ ends. Replication of viral genomic RNA, which takes place in close association with host cell membranes, involves the initial synthesis of the complementary minus sense RNA … …American Journal of Infectious Diseases, Vol. 2, Issue 1 · 31 Mar 2006 · 7,317 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Lignite and Firewood Co-combustion in a Furnace for Tobacco Curing ApplicationNakorn Tippayawong, Chutchawan Tantakitti, Satis ThavornunCo-combustion of lignite and firewood was investigated for an application in tobacco curing industry in Northern Thailand. Extensive experiments have been carried out in a newly developed furnace suitable for small curing unit, in place of locally made furnace. The aim of this investigation is to evaluate the performance of the combustion chamber in the required thermal output range for … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 6,905 accessesView PDFCite
Research ArticleOpen accessIn the abstractLearning Dynamics in the Cobweb Model with Heterogeneous ProducersCarl Chiarella, Xue-Zhong HeIn this study we investigate the nonlinear dynamics of the traditional cobweb model with two types of heterogeneous producers who are risk averse and seek to learn the distribution of asset prices, in terms of the sample mean and variance of historical prices, using the Arithmetic Learning Processes (ALP) over different window lengths. We show that heterogeneity has a double … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 15 Dec 2005 · 7,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractProperties of Absolute Stability in the Presence of Time LagsM. De la Sen, J. L. Malaina, A. Gallego, J. C. SotoThis study is concerned with the properties of absolute stability independent of the delays of time-delay systems, possessing non commensurate internal point delays, for any nonlinearity satisfying a Popov’s- type time positivity inequality. That property holds if an associate delay-free system is absolutely stable and the size of the delayed dynamics is sufficiently small. The results are obtained for nonlinearities … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,571 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Model Mathematical Models for the Dynamics of Tuberculosis in Density-dependent Populations: The Case of Internally Displaced Peoples' Camps (IDPCs) in UgandaA. Ssematimba, J. Y.T. Mugisha, L.S. LuboobiMathematical models are formulated to establish the conditions (restrictions) on the size of the area occupied required minimizing and thereafter eradicating tuberculosis. Both numerical and qualitative analyses of the model are done and the effect of variation in the area size and recruitment rate on the different epidemiological groups is investigated. The results of the analysis show that there exists … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 6,895 accessesView PDFCite
