Research ArticleOpen accessIn the abstractSolid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanWaste management became focus of attention of many researchers and scientists in the last half century due to its vital importance. Waste management covered waste source reduction in general, by recycling, reusing, composting, incineration with or without energy recovery, fuel production and land filling. A common approach of waste management models were for specific problems with a limited scope (like … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,939 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Ibuprofen and Paracetamol in Binary Mixture Using Chemometric-Assisted Spectrophotometric MethodsWafaa S. HassanThree methods are presented for simultaneous determination of ibuprofen and paracetamol without previous separation. The first method depends on first derivative UV spectrophotometry, with zero-crossing measurement. The first derivative amplitudes at 230 and 290 nm were selected for the assay of ibuprofen and paracetamol, respectively. The second method depends on first derivative of the ratio-spectra by measurements of the amplitudes … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 8,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Hormetic Behaviour of Drugs Binding to Different Redox States of Amine Oxidase EnzymesDeepak Narang, G. Reid McDonald, David J. Smith et al.Classical monoamine oxidases and copper-containing semicarbazide-sensitive amine oxidases are drug targets for a variety of established and novel pharmaceuticals used to treat conditions such as depression, Parkinsonism and inflammatory disorders. Development of enzyme inhibitors, both historically and currently, assumes an underlying adherence of these enzymes to Michaelis-Menten kinetic principles. In this mini-review, we discuss historical data from several laboratories and … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 6,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Triggers for Intervention in Aging, Disease and TraumaJoan Smith SonnebornHormesis refers to the ability of a chemical or physical agent to condition the physiological state of an organism to tolerate stress with low doses of otherwise harmful agents. Evolutionary evidence shows that the survival and longevity of species hinge on their optimal ability to resist stress challenge. Hormesis is a potent strategy to stimulate latent repair processes to tolerate … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Construction Technologies that Enables Environmental Protection: Rubberized ConcreteG. Senthil Kumaran, Nurdin Mushule, M. LakshmipathyThroughout the world, the disposal of used tires is a major environmental problem causing environmental hazards such as breeding ground for mosquitoes, producing uncontrolled fire and they are contaminating the soil and vegetation. Therefore, there is an urgent need to identify alternative outlets for these tyres, with the emphasis on recycling the waste tyre. Concrete is an excellent structural material … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpraying Effects on Goat Welfare in Hot and Humid ClimateNazan Darcan, Fatin Cedden, Okan GuneyHeat stress is one of the major factors adversely affecting animal welfare and thus economic benefits of farms. This study was designed to determine the effects of three different spraying methods on goats for reducing heat stress. Thirty goats divided into three groups for the trial (One time sprayed a day: OTS, Two times sprayed a day TTS and Non-sprayed: … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdoption of Peer-To-Peer Assessment in a Computing Skills CourseMansoor Al-A'aliThe process of peer-to-peer assessment brings great benefits to the teaching and learning process. This paper presents a peer assessment model which was applied to students enrolled in a generic computing skills course. In order to measure the effectiveness of this proposed model, students had to evaluate their colleagues based on predefined criteria and a comparison is presented between the … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractImportance of blood gas measurements in perinatal asphyxia and alternatives to restore the acid base balance status to improve the newborn performanceH. Orozco-Gregorio, D. Mota-Rojas, M. Alonso-Spilsbury et al.Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentrations. Blood gas … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,631 accessesView PDFCite
Research ArticleOpen accessIn the abstractResponsibilities of Graduate Student: The Review of Research Student PoliciesNorhasni Zainal Abiddin, Mel WestThe researcher’s previous study had found that most research students did not fully used their graduate research student policy as point of reference. Objective was to review the contents of the research student policy and the benefits of having systematic policies for the supervision of research students. Total of 40 graduate research student policies had been studied from 40 well … …Journal of Social Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 8,040 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimplification of Sun Tracking Mode to Gain High Concentration Solar EnergyOmar Aliman, Ismail Daut, Muzamir Isa, Mohd Rafi AdzmanPower conversion from solar thermal energy to electrical energy is still very cost-intensive. Serious effort has to be given in the development of the concentrator or heliostat structure expenditure which contributing the most expensive component in a central receiver solar power plant. With current development to find alternatives and lower down the capital, a new mode of sun tracking has … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,187 accessesView PDFCite
