Research ArticleOpen accessIn the abstractThe Diatom Stratigraphy of Rawapening Lake, Implying Eutrophication HistoryTri Retnaningsih Soeprobowati, Suwarno Hadisusanto, Peter Gell, Atun ZawadskiProblem statement: The use of diatoms to reconstruct past ecological conditions in lakes is well established. Diatoms are microscopic algae that forms siliceous frustules which allow them to preserve well in sediments. Rawapening Lake is one of 15 Indonesian lakes identified as 2010-2014 National Priority Lakes. Naturally, Rawapening is a tectono-volcanic lake. In the early 1900s, the sole outlet of … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 15 Jun 2012 · 7,716 accessesView PDFCite
Research ArticleOpen accessIn the abstractGreenhouse Gas Emissions: Quantifying Methane Emissions from LivestockRafiu O. Yusuf, Zainura Z. Noor, Ahmad H. Abba et al.Problem statement: The rearing of animals for domestic consumption and export invariably lead to the production of methane as a product of digestion. This study investigated the emission of methane from Malaysian livestock between 1980 and 2008. Approach: Seven categories of animals identified were camel, buffalo, sheep, goats, horse, pigs and poultry. The estimation of methane was based on the … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2012 · 9,538 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Soil Biological Properties of Natural and Planted Forests in the Malaysian Tropical Lowland Dipterocarp ForestDaljit Singh Karam, Arifin Abdu, O. Radziah et al.Problem statement: A study was conducted to evaluate and compare the soil biological properties of a natural forest and an 18-year-old stand of Shorea leprosula in Chikus Forest Reserve, Perak, Malaysia. Approach: Soils were sampled at depths of 0-15 cm (topsoil) and 15-30 cm (subsoil) in six subplots (20×20 m) of natural forest (C1) and of a planted S. leprosula … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 29 Jul 2011 · 7,961 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Lead, Cadmium and Copper Concentrations in Bee Honey and Edible MolassesAhmed Hassan, Mahmoud A.A. Ghandour, Azza M.M. Ali, Hazim. A. MahranProblem statement: Content of Cadmium, lead and copper in 26 bee honey samples from different places of Assiut governorate (south of Egypt) and three different botanical origins (Clover, Multi-flower and Citrus) in addition to four edible molasses samples from Egypt market were evaluated by Differential Pulse Anodic Stripping Voltammetry (DPASV) in Briton-Robinson buffer solution at pH ~ 2.1, as well … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Analysis of Coagulase Gene Polymorphism in Clinical Isolates of Methicilin Resistant Staphylococcus aureus by Restriction Fragment Length Polymorphism Based GenotypingM. Himabindu, D. Sugapriya Muthamilselvan, Dillip Kumar Bishi, Rama S. VermaProblem statement: To investigate coagulase gene variants through Restriction Fragment Length Polymorphism (RFLP) amongst clinical isolates of Methicillin-Resistant Staphylococcus Aureus (MRSA) collected from Chennai based hospitals. Approach: A total of 85 MRSA clinical isolates collected from various clinical sources were studied for the molecular typing purpose. To perform coagulase gene typing, the repeated units encoding hypervariable regions of the Staphylococcus … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 8,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtective Effects of Covalent Cross-Linking on Proteolysis of Human Coproporphyrinogen Oxidase and Implications for PorphyriaAhmed W. Jafri, Jason R. Stephenson, Justin B. Morgenthaler et al.The effects of covalent cross-linkers on the enzyme, coproporphyrinogen oxidase, had been previously studied but their role in protecting the enzyme from protease cleavage has not been evaluated. Therefore, we examined how the cross-linker bis (sulfosuccinimidyl) suberate (BS3) affects the ability of trypsin to digest purified, wild type recombinant human coproporphyrinogen oxidase and selected mutants. Following incubation, the apparent molecular … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of the Detoxification on the Shrinkage Temperature and pH of Chromium Leather Waste, Another Promising Way for the Tannery PollutionA. Malek, M. HachemiThe leather tannery industry produces a significant amount of solid chromium waste. Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and alternative disposal methods are needed. This research describes the possibility of decrease of the shrinkage temperature and to increase the pH value of leather waste by detoxification treatment with use of tartrate … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,114 accessesView PDFCite
