Research ArticleOpen accessIn the abstractRemediation of Methyl Tert-Butyl Ether (MTBE) Contaminated Water by Using In situ Catalytic and Biological Combined TechniquesA. Nikpay, H. Kazemian, M. SadeghiThe hydrolysis reaction of Methyl Tert-Butyl Ether (MTBE) into biodegradable products was studied on as-synthesized and commercial H-MFI zeolites. The effect of synthesis procedure and SiO2/Al2O3 ratio was investigated. The results obtained were indicated that H-MFI zeolites were effective in MTBE hydrolysis and increasing of the Si/Al ratio promotes the hydrolysis reaction. The amount of produced TBA was always lower … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn Vitro Metabolism Studies of Polybrominated Diphenyl Ethers Using Rat and Human Liver MicrosomesShun Wen Cheng, Kathleen Randall, Anne T. KotchevarA number of studies have recently reported the bioaccumulation of the commonly used fire retardants, Polybrominated Diphenyl Ethers (PBDEs), in humans and wildlife. Exposure of animals to PBDEs has been shown to result in developmental neurological, reproductive abnormalities and the disruption of endocrine function. Thyroid hormone equilibria was also shown to be altered by PBDE exposure. There is evidence that … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficacy of Pravastatin in Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI) and Protease Inhibitor (PI)-based HAART in HIV-Infected PatientsSusan A. Eaton, Anita P. Rahman, Sean T. Nguyen et al.Pravastatin has generally been considered a safe and effective option for HIV-infected patients on highly active antiretroviral therapy (HAART). However, pravastatin concentrations are known to significantly decrease with concomitant efavirenz (EFV) use. Currently there are no studies determining if these reductions in pravastatin possibly translate into an attenuation of its lipid lowering efficacy when used in HIV-infected patients on non-nucleoside … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 6,959 accessesView PDFCite
Research ArticleOpen accessIn the abstractLightning Over-Voltages on Amman-Aqaba 400 KV LineGhassan Halasa, Ibrahim Badran, Hafez El-ZayyatAn attempt is made to evaluate the lightning over-voltage failure rate for Amman- Aqaba 400kV transmission line by studying the geographical and temporal characteristics of lightning causing the line forced outages. The line was divided into three sections based on weather and pollution conditions. It was found that the line failure rate due to lightning over-voltages is low compared to … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 6,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractTreatment of Landfill Leachate using Limestone/Sandstone Filters Under Aerobic Batch ConditionsAbdel E. Ghaly, M.A. Kamal, N.S. Mahmoud, R. CoteThe suitability of a passive technology, consisting of filters composed of a mixture of limestone and sandstone rocks, for the treatment of landfill leachates containing 6.6 mg Lˉ1 iron and 1.8 mg Lˉ1 manganese were investigated. The limestone and the limestone/sandstone filters successfully removed iron from the prepared solutions. The filters removed on average a minimum of 97.60% of the … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,066 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Temperature on the Performance of Limestone/Sandstone Filters Treating Landfill LeachateAbdel E. Ghaly, M.A. Kamal, R. CoteThe ability of limestone and limestone/sandstone filters to remove dissolved iron and manganese from landfill leachate under field conditions were investigated. The results showed that the precipitation of iron and manganese were affected by temperature and time. Most of iron was removed from solution within the first 10 min at 20°C while the removal of iron from solution took much … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Adaptive Modulation Scaling Scheme for Quality of Services Ensurance in Wireless Sensor NetwoksYong Yuan, Zongkai Yang, Jianhua HeEnergy consumption has been a key concern of data gathering in wireless sensor networks. Previous research works show that modulation scaling is an efficient technique to reduce energy consumption. However, such technique will also impact on both packet delivery latency and packet loss, therefore, may result in adverse effects on the qualities of applications. In this study, the problem of … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractReplacement Heifer Selection in A Beef Cattle HerdAkin Pala, Roger McCrawThe relationship between a heifer's weaning weight and her fertility and weaning weight of her calves was studied. Also investigated was the effect of dam amount of fat (DAF=dam weaning weight/weaning height) on heifers' ability to breed and rebreed. This is similar to Body Mass Index (BMI) calculated for humans. The relationship of dam's average daily gain from birth to … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,814 accessesView PDFCite
