Research ArticleOpen accessIn the abstractThe Development of A New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part I: Design of the Detection System and ApplicationsEric Carnes, Ebtisam WilkinsA portable, flow-through amperometric immunoassay system utilizing a newly designed immunosensor has been developed for the detection of bacteria. A sandwich scheme of immunoassay involving two stages of immunoreaction was employed using Escherichia coli as a model. E. coli antibodies were immobilized on Toray carbon paper to create a disposable immunofiltration membrane. Detection of the bacteria was achieved through the … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2006 · 6,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of Magnetic Paper from Kenaf: Lumen Loading and in situ Synthesis MethodC. H. Chia, S. Zakaria, S. Ahamd et al.Magnetic papers have been successfully prepared from unbleached kenaf (hibiscus cannabinus) kraft pulps via the lumen loading and in situ synthesis process. The lumen loading method allows the magnetic fillers to be introduced into the lumen of fibres and at the same time leaving the external surfaces free from filler, resulting the better inter-fibre bonding and subsequently its papermaking properties … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractBoosted Regression Estimates of Spatial Data: Pointwise InferenceMarco Di Marzio, Charles C. TaylorIn this study simple nonparametric techniques have been adopted to estimate the trend surface of the Swiss rainfall data. In particular we employed the Nadaraya-Watson smoother and in addition, an adapted-by boosting-version of it. Additionally, we have explored the use of the Nadaraya-Watson estimator for the construction of pointwise confidence intervals. Overall, boosting does seem to improve the estimate as … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,352 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Performance of a Solar Heat Storage Accumulator Used For Greenhouses ConditioningMejdi Hazami, Sami Kooli, Meriam Lazaar et al.The use of solar energy for greenhouse heating has gained an increasing acceptance during the last years. Active solar systems applied to greenhouses can supply a significant part of the heating requirements. However, there are some problems related to the cost of the heat collection unit and the heat storage methods. In this context several techniques were born. The most … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Effect of Counterface Materials on Interface Temperature and Friction Coefficient of GFRE Composite Under Dry Sliding ContactN. S.M. El-Tayeb, B. F. Yousif, P. V. BrevernNowadays, there is an increase interest in polymeric composite materials for high-performance in many industrial applications. In other words, the tribo-studies on polymeric materials are growing fast to enhance the polymeric products such as bearings, seals, ring and bushes. The current work presents an attempt to study the correlation between the type of counterface material and frictional heating at the … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,026 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Investigation of Flow Control by Suction and Injection on a Subsonic AirfoilM. H. Shojaefard, A. R. Noorpoor, A. Avanesians, M. GhaffarpourThis study presents a numerical study concerning flow control by suction and injection. The case studied is the flow field over a subsonic airfoil with four suction and injection slots on the suction side of the airfoil. Five different angles of attack, 0, 5, 10, 13.3 and 20 with the Mach number of 0.15 are studied. Three cases are studied … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,434 accessesView PDFCite
Research ArticleOpen accessIn the abstractCost Comparison between Stone Mastic Asphalt and Asphalt Concrete Wearing CourseSalihudin Hassim, Rohimah Khoiriyah Harahap, Ratnasamy Muniandy et al.Stone Mastic Asphalt (SMA) technology has been introduced to Malaysia since the 1990’s. Since then, several trials had lain projects had been initiated for the purpose of evaluating the mix on local road condition. However, the acceptability of SMA is still quite discouraging among the local road authorities. This setback is probably due to the misconception on the high initial … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 7,019 accessesView PDFCite
Research ArticleOpen accessIn the abstractConservation of “Partial Vorticity” with Application on Hydraulic JumpsHarald NaeserIn two preceding works, the idea of partial conservation theorems was introduced and conservation equations for partial energy and partial angular momentum were established. A similar conservation theorem for partial vorticity of incompressible fluids is established here. The vorticity vector is divided into two elements (both denoted “partial vorticity”) and their conservation equations established separately. They show that, in addition … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,707 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Analysis of Furniture Hardware Industry in TurkeyTuncer DilikFurniture hardware plays an important role in the appearance, comfort and function of the furniture. In this study, Turkish furniture hardware companies were examined for their technical and economical characteristics, production materials, standards and surface treating methods, legal structures as well as foreign and domestic trade policies. Altogether, 67 companies accounting for 80% of the hardware production were examined. In … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh Density Groundwater Flow, Major-ion Chemistry and Field Experiments in a Closed Basin: Fuente de Piedra Playa Lake (Spain)Rodríguez-Rodríguez Miguel, Benavente Herrera José, Moral Martos FranciscoThis study presents the results of 10 years of field investigation in Fuente de Piedra Playa Lake located in southern Spain. These field observations along the playa's shore revealed evidence of a forced convective flow and the existence of density interface below the playa basin. An upward flux of groundwater from underlying formations could be a considerable part of its … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,310 accessesView PDFCite
