Research ArticleOpen accessIn the abstractAnalysis of Leakage Current to Predict Insulator Flashover Using Artificial Neural NetworkN. Narmadhai, A. Ebenezer JeyakumarProblem statement: The phenomenon of flashover in polluted insulators has been continued by the study of the characteristics of contaminating layers deposited on the surface of insulators in high voltage laboratories. In the literature, Experimental investigations have been carried out on a real insulator or a flat plate model of insulators under high voltage application. This study proposed the Equivalent … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,618 accessesView PDFCite
Research ArticleOpen accessIn the abstractVulnerability and Pollution Risks in the Alluvial Aquifer of Tebessa-MorsottS. Kachi, N. Kherici, N. KachiWe studied the vulnerability and risks of pollution of the alluvial aquifer of Tebessa-Morsott that ranks amongst the major groundwater reservoirs of the region. The method used to asses groundwater vulnerability was the DRASTIC method, based on seven parameters that affect and control the groundwater flow: Depth to groundwater, Impact of the unsaturated zone, net recharge, aquifer media, hydraulic conductivity, … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Challenge of the Hospitals and Health Care Systems in Preparation for Biological and Chemical Terrorism AttackEldo Ermenegildo Frezza MDIn the present study a few aspects of planning for terrorism events that expose large numbers of people to contamination are discussed. Many issues were considered as an absolute requirement for implementation of NBC response: 1) policy, 2) plan and 3) emergency department response to surge capacity. Key elements of the healthcare facility response plan include prompt recognition of the … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,390 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethyltert-butyl Ether (MTBE) Degradation by a Microbial ConsortiumS. B. Mortazavi, A. Nikpey, A. Rezaee et al.Methyl tert-butyl ether (MTBE) is added to reformulated gasoline to meet the 1990 Clean Air Act directives. Widespread use of MTBE in gasoline has resulted in groundwater contamination. Because of its undesirable effects on drinking water and ecologically harmful effects, MTBE removal has become a public health and environmental concern. In this study, we have isolated a mixed bacterial culture … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Aliphatic Hydrocarbons in Sediments of Shatt Al-Arab River, Southern Iraq, North East Arabian GulfWisam Abdul-Ameer FaridShatt Al-Arab River is one of the important rivers for water supply, industry and irrigation in Basrah City, south of Iraq. It's also supply drinking water to users in the region. Despite the significance of this river, there is a lack of previous studies dealing with petroleum pollution especially for geochemical studies of organic matter in the river sediments using … …American Journal of Environmental Sciences, Vol. 13, Issue 6 · 29 Jan 2018 · 7,458 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordContamination of Nitrate in Groundwater and Evaluation of Health Risk in Bachok, Kelantan: A Cross-Sectional StudyAida Soraya Shamsuddin, Sharifah Norkhadijah Syed Ismail, Emilia Zainal Abidin et al.High concentrations of nitrate through drinking water have been associated with health problems. This cross sectional study sought to determine the level of nitrate concentrations in private well water and the association to the disease caused by nitrate among population of Bachok, Kelantan. The concentrations of nitrate in 256 wells were sampled from September to October 2015. About 126 respondents … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 23 Jan 2016 · 9,471 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordRemediation 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
