Research ArticleOpen accessIn the abstractComparison of Twelve Dielectric Moisture Probes for Soil Water Measurement under Saline ConditionsM. Inoue, B.A. Ould Ahmed, T. Saito, M. IrshadRecently the research on the determination of soil water content and electrical conductivity using automated technique has received tremendous attention. Selecting the type of system that should be used for soil water measurement under saline conditions depends on its precision. A laboratory study was carried out to measure the soil water content (θ) and soil solution electrical conductivity (ECw) using … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicity of Reference Sediment SamplesK. R. Beg, S. AliThis study was done to determine toxicity of certified reference sediment to be used for quality assurance in sediment toxicity testing program. Certified Reference Harbor Sediment (HS-4B for PAHs) and Estuarine Sediment (LGC-6137 for Trace Metals) were procured commercially from LGC Company, UK, and repeatedly analyzed against solid phase Microtox toxicity assay to determine EC50 values. Both PAHs rich and … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Approach to Determine the Effects of MS Environment using the Portable GPS Receiver with Built-in AntennaWan Azlan Wan Zainal Abidin, Kiyotaka Fujisaki, Mitsuo TateibaCommunication impairment on the Mobile Satellite (MS) path for non-geostationary satellite is mainly due to effect of multipath and shadowing. In order to study the signal quality received by the MS user, a receiver system that has similar characteristics to the actual receiver used by the MS user should be used. This study presents a novel approach to determine the … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Speech Processing Strategies in Cochlear ImplantsKouachi Rouiha, Djedou Bachir, Bouchaala AliCochlear implants can restore partial hearing to profoundly deaf people; the main function of these prostheses is to electrically stimulate the auditory nerve using an electrode array inserted in the cochlea. The acoustic signal is picked up by a microphone and analyzed. Then the extracted parameters of the signal are coded to generate electrical signals reconstituting the original signal. Currently … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,840 accessesView PDFCite
Research ArticleOpen accessIn the abstractCellular and Some Biochemical Changes in Blood and Peritoneal Fluid Constituents in Awassi Lambs Following Elective CastrationMohammad B.F. AL-Zghoul, Raida K. AL-Rukibat, Abdelsalam Q. Talafha et al.No reports could be cited in the recent literature concerning the effects of surgical castration on blood and peritoneal fluid constituents in lambs. The purpose of this study was to evaluate the effects of surgical castration on cellular and some biochemical parameters of blood and peritoneal fluid in Awassi lambs. Eight, clinically healthy, 5-month-old, Awassi lambs were surgically castrated. Peritoneal … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,244 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntisporulant Activity of Watery Extracts of Plants against Sclerospora graminicola Causing Downy Mildew Disease of Pearl MilletS.A. Deepak, G. Oros, S. G. Sathyanarayana et al.Watery extracts of forty plant species commonly growing in across India have been screened for antisporulant activity against Sclerospora graminicola (Sacc.) Schroet., the causative agent of pearl millet downy mildew. The collection represented 38 genera of 30 families. The extracts of thirteen species did not show any effect, whereas the activity of extracts of Allium sativum, Clematis gouriana, Evolvulus alsinoides, … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 7,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment on Biocides Bioaccumulation in Mullet Liza klunzingeri in Kuwaiti Waters, off the Arabian GulfA.H. Bu-Olayan, B. V. ThomasBiocides, such as formaldehyde (HCHO), sodium hypochlorite (NaOCl) and glutaraldehyde (C5H8O2) that are commonly used in thermal, desalination and power plants and industries were tested on the commercially important mullet fish, Liza klunzingeri to determine the environmental contamination in the stressed ecosystem of Kuwait Bay sites. Multi-factor Probit analysis toxicity tests (96 h) on L. klunzingeri showed the lowest observed … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,772 accessesView PDFCite
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
