Research ArticleOpen accessIn the abstractDevelopmental Design of Anaerobic Wetland System for Mining Waste Water TreatmentMuhammad Aqeel Ashraf, Mohd. Jamil Maah, Ismail YusoffProblem statement: Tin mining is one of the oldest industries in Malaysia that have started since 1820s. These mining activities have resulted in about 13,700 hectors of tin tailings throughout the peninsula. These tailings have created numerous environmental problems such as threat to natural reserves due to landscape changes, damage to natural drainage, pollution and destruction of natural habitats. Approach: … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 10 Oct 2011 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Different Exogeneous Compounds on Biosorption of EndosulfanDeepika Dave, A. K. DikshitProblem statement: Organochlorine pesticide endosulfan is widely used as a replacement for DDT and dieldrin in many parts of the world. Presence of residual pesticides in the water, air and soil environment was confirmed since 1960s. Such Persistent Organic Pollutants (POPs) are of concern because of their long-term subtle effects on hormones, the immune system and reproduction. Therefore, it becomes … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Consortia from Taptapani Hot Water Springs for Mining Effluent TreatmentPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriProblem statement: Soluble sulfate load in effluent is a crucial problem from mining industries. The study involved isolation of efficient Sulfate Reducing Bacterial (SRB) consortium from hot water spring for bioremediatrion of sulfate contaminated waste water. Approach: The enriched bacterial consortium was isolated in medium DSMZ 16695. The sulfate reduction efficiency was measured by turbidometric method. The Km and Rmax … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Technique for Extraction Foetal Electrocardiogram using Adaptive Filtering and Simple Genetic AlgorithmMahmoud Ahmed Suliman Ali, XiaoPing ZengProblem statement: Foetal electrocardiogram (FECG) was the best method used to diagnose Foetal heart problem. Knowledge of the foetal heart signal prevents Foetal problems in the earlier stage. Recently, there has been a growing interest in noninvasive method rather than the old invasive method which was more risky for the mother's health. The most significant problem in noninvasive method is … …Current Research in Biostatistics, Vol. 1, Issue 2 · 31 Dec 2010 · 10,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabrication of Composite Material from Sea Mussel Shells and White Clay as a Versatile SorbentSingto Sakulkhaemaruethai, Churairat Duangduen, Weraporn Pivsa-Art, Sommai Pivsa-ArtProblem statement: The removal of heavy metals contaminated in aqueous solution/wastewater has been causing worldwide concern. However, the adsorbent materials are usually limited due to their high cost and environmentally benign. To overcome the above-mentioned disadvantages, low-cost and effective adsorbents are in demand. Approach: In this study, the sea mussel shells/natural clay beads were prepared for using as low-cost sorbent … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Signal Detection of Sensor Array Units Using 5-3-1 Rule Based Matched Filter Algorithm with Intelligent IdentifiersMahmoud Z. IskandaraniA novel approach to signal detection and identification was developed and tested. The new algorithm was based on provision of tagging a Matched Filter (MF) with identifiers to recognize the source signal with and without noise, so that classification can be carried out. The algorithm was applied successfully to chemical Sensor Array Units (SAU). Problem statement: Signals obtained from chemical … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,846 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption Study of Electric Arc Furnace Slag for the Removal of Manganese from SolutionC. L. Beh, Luqman Chuah, Thomas S.Y. Choong et al.Problem statement: Steel making slag from Electric Arc Furnace (EAF) is an abundant by-product in Malaysia steel making industry. It has potential to be used for heavy metal removal from contaminated water or waste water. Approach: The aim of this study was to investigate the characteristic and behavior of manganese removal by using EAF slag for efficient metal removal. The … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Pb(II) on Spent Leaves of Green and Black TeaAntonio Zuorro, Roberto LavecchiaProblem statement: In recent years much attention has been focused on the use of biomass residues as low-cost adsorbents for the removal of heavy metal ions from contaminated waters. Spent tea leaves, an abundantly available material that is currently disposed of as a solid waste, are potentially suitable for such applications. Approach: To provide some information on the adsorption properties … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 9,596 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Health and Toxic Adverse Effects of Fusarium Fungal Mycotoxin, Fumonisins, on Human PopulationW. M. Wan Norhasima, A. S. Abdulamir, F. Abu Bakar et al.Problem statements: Fumonisin was a mycotoxin produced mainly by fungi belonging to the genus Fusarium in various foods and feeds. They occurred worldwide and were found predominantly in corn and in corn-based animal feeds and also can be found in other crops. Contamination of food and feed with fumonisins has been implicated in and associated with a number of diseases … …American Journal of Infectious Diseases, Vol. 5, Issue 4 · 31 Dec 2009 · 9,034 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Crude Oil and Spent Oil on Clarias garipinus: A Typical Marine FishA. M. Gbadebo, A. M. Taiwo, O. B. OlaProblem statement: Petroleum hydrocarbon and petroleum residue (i.e., spent oil) remains the foremost pollutants to the fish communities in various aquatic media-ponds, streams, rivers, creeks, coastal and marine environments through indiscriminate disposal of oil contaminated drilling muds, cutting and oil spillages.
