Research ArticleOpen accessIn the abstractPush-pull Strategy with Trap Crops, Neem and Nuclear Polyhedrosis Virus for Insecticide Resistance Management in Helicoverpa armigera (Hubner) in CottonP. Duraimurugan, A. RegupathyInsecticide resistance in Helicoverpa armigera (Hubner) is a major threat to cotton production in India. The virus infection was found to increase the susceptibility of H. armigera to the insecticides. But, use of Nuclear Polyhedrosis Virus (NPV) on a larger scale and on cotton due to leaf alkalinity poses certain practical problems. Hence, studies were carried out to assess the … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 9,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractResidual Defects in Silicon Implanted with Boron and Phosphorous IonsM. JadanAccumulation of radiation defects in Si implanted with B+ or P+ ions, and formation of the residual extended defects (dislocation loops, rod-like defects) in the process of successive thermal treatment have been studied. The anomalies observed in the formation of the extended defects are associated with the elastic stresses in the damaged regions affecting the process of radiation defects clustering. …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractPeriodicity of the HIV/AIDS Epidemic in a Mathematical Model that Incorporates ComplacencyFlugentius Baryarama, Livingstone S. Luboobi, Joseph Y.T. MugishaAn HIV/AIDS model incorporating complacency for the adult population is formulated. Complacency is assumed a function of the number of AIDS cases in a community with an inverse relation. A method to find the equilibrium state of the model is given by proving a stated theorem. An example to illustrate the application of the theorem is also given. Model analysis … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,631 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of HCV Components and Pathological Reactions in Apoptotic Hepatocytes from Chronically HCV-infected PatientsViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Analysis of Hepatitis C Virus (HCV)-infected hepatocytes at the cellular level may contribute to elucidate the mechanisms of HCV pathogenesis. In this work, the presence of HCV components and pathological reactions in apoptotic hepatocytes from chronic HCV-infected patients were studied by electron microscopy and confocal microscopy. Eight samples of liver biopsies from patients with chronic hepatitis C were studied by … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,907 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecline of Betula ermanii with Special Reference to Ozone Concentration at Mt. Mae-Shirane, Oku-Nikko, JapanY. W. Feng, N. Ohta, H. ShimizuDuring June to October 2000 and 2001 we measured the height, Diameter at Breast Height (DBH) and stand density of Betula ermanii trees at Mt. Mae-Shirane, Japan and the ozone concentration there to explore the relationship between ozone concentration and the decline of B. ermanii trees on the mountain. Height, DBH and stem volume were lower on the southeast-facing slope … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,055 accessesView PDFCite
Research ArticleOpen accessIn the abstractBy-pass Devices as Effective Means of Protection from the Hydraulic HammerKhalid S. Al-RababaSwitching-off the parallel working pump units causes sudden discharge changes in parallel pipe lines, as a result of that hydraulic shocks takes place. The damping of these shocks can be achieved by the installation of the by-pass devices between the parallel lines of the piping system. The analytical calculations demonstrate that the reduction in hydraulic shocks reaches 40% and considerable … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractSocial-economic and Ecological Criteria of Noise ControlM. A. Al-NawaflehWhen designing new and/or modifying pre-existing equipment, the problem of economic feasibility is always of prime importance . However, the economic feasibility is often a matter of discussion in various social aspect. To operate no aesthetic, noisy, dusty, gazed heavy machine with large number of visually fixed moving parts and gearing, it is often dangerous and even risky. The work … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransducer for Tension Force Measuring of Strip MaterialsEmad Said AddasiIn winding-up motor drive systems, such as that used in textile industry, it is very important to get a constant tension force for the winding strip material (thread) and to reduce its oscillations. This study recommends a transducer with a special design to be used in the mentioned motor drive systems. By using a piston damper, spring, levers, slider and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Impact of E. Coli O111 Outbreak in 1995 in AustraliaShahjahan Ali Khandaker, Mohammad AlauddinIncreased incidence of food-borne illnesses is a matter of significant concern for the community and the government alike. An outbreak of E. coli O111 that occurred in Australia in 1995 affected 200 people of whom 22 developed HUS while one person died. This study analyses the economic costs of the outbreak. The total cost of the outbreak is estimated to … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractVariation in the Thickness of A Fluid Interface Due to Internal Wave Propagation: A Lattice Boltzmann SimulationJ.M. Buick, D.B. Hann, J.A. CosgroveThe change in the thickness of an interface between two immiscible fluids due to the propagation of an internal capillary-gravity wave along the interface is considered using a Bhatnagar, Gross and Krook (BGK) lattice Boltzmann model of a binary of fluid. The vertical thickness of the interface is recorded from the simulations since this is the most easily measured quantities … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,248 accessesView PDFCite
