Research ArticleOpen accessIn the abstractThe Influence of pH on Nonlinear Refractive Index of Bromophenol BlueF.Z. Henari, K.G. CulliganProblem statement: Bromophenol blue is a pH indicator, a kind of chemical that changes colour when pH goes up or down over a narrow linear dynamic range of 3.0-4.6 pH units. Therefore a good approach must be taken to extend the linear response of the indicator in order to have simple calibration and precise measurements of PH sensors. The purpose … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 15,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethicilin Resistant Staphylococcus aureus Carriage amongst Healthcare Workers of the Critical Care Units in a Nigerian HospitalA. Fadeyi, B.O. Bolaji, O.O. Oyedepo et al.Problem statement: Methicilin Resistant Staphylococcus Aureus (MRSA) Nosocomial Infection (NI) outbreaks and prevalence among various populations are well reported in literature particularly for developed countries. NI due to MRSA is a known cause of increased hospital stay, cost, morbidity and mortality especially among the critically ill. There is paucity of information on MRSA in developing nations including the carriage by … …American Journal of Infectious Diseases, Vol. 6, Issue 1 · 31 Mar 2010 · 9,100 accessesView PDFCite
Research ArticleOpen accessIn the abstractReflectivity of Reflectarrays Based on Dielectric SubstratesM. Y. Ismail, M. Inam, A. M.A. ZaidiProblem statement: Reflectarrays provide a low cost and low profile solution for antennas required for high gain applications but their use is restricted in some applications due to the narrow bandwidth and high loss performance. These performance limitations can be attributed to different sources of reflectivity of the reflectarrays. This work provides a thorough investigation on the reflectivity performance of … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractMobile Phone Base Station Radiation Study for Addressing Public ConcernAiman Ismail, Norashidah Md Din, Md Zaini Jamaludin, Nagaletchumi BalasubramaniamProblem statement: The proliferation of mobile phone base stations had increased concerns from the public on the radio frequency radiation hazards that might come from them. The world wide public concern involved health risk due to radio frequency radiation. In Malaysia also public interest has increased, although it is not as intense as probably in other parts of the world, … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicroanatomy and Histochemistry of the Salt Glands of the Kentish Plover, Charadrius alexandrines (Aves, Charadriidae)Bashir M. JarrarProblem statement: Histological and histochemical investigations on the salt glands of birds are very limited. The present study was performed to characterize the microanatomy and histochemistry of the salt glands of the Kentish plover (Charadrius alexandrines). Approach: Salt glands of the bird under study were fixed, dehydrated, cleared, impregnated and blocked out by paraffin wax. Paraffin sections were utilized in … …OnLine Journal of Biological Sciences, Vol. 9, Issue 3 · 30 Sep 2009 · 6,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetically Modified Organism Trade Route and Biosafety-Is It a Failing Synthesis?Debdatta Dobe, Rohini SenProblem statement: GM regulations have spawned international conflicting reactions especially between US and EU, with countries requiring food aid caught midway. This article covers the following issues: Whether biotechnology policies of other countries affect the developing countries’ trade in agricultural crops?" Does unregulated GM expansion and contamination, render the system fallacious? Can there be synthesis between trade and environment? Approach: … …American Journal of Economics and Business Administration, Vol. 1, Issue 3 · 30 Sep 2009 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation of WO3 Nanoparticles Using Cetyl Trimethyl Ammonium Bromide Supermolecular TemplateNilofar Asim, S. Radiman, M. Ambar bin YarmoProblem statement: WO3 is one of the most interested metal oxides because of its application as catalysts, sensors, electrochromic devices, ceramic, solar cell, pigments and so on. More investigation is needed to find the good and low cost method for preparation of WO3 nanoparticles with uniform morphology and narrow distribution using a surfactant mediated method. Approach: In this study, the … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,699 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeochemical, Petrographic and Magnetic Characteristics of Spinel Lherzolite Mantle Xenoliths from Jabal Remah Volcano, JordanAhmad Al-Malabeh, Tayel El-Hasan, Mahdi LataifehPeridotite ultramafic mantle xenoliths are occurring abundantly in the Harrat Al-Shaam basaltic province. Jabal Remah volcano is located in the Jordanian parts of the plateau and contains considerable amounts of mantle xenoliths within its pyroclastic successions. Mineralogical investigations show that the xenoliths are mostly of the spinel lherzolite type, which are characterized by a protogranular texture. Modally, the xenoliths are … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,183 accessesView PDFCite
