Research ArticleOpen accessIn the abstractPREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Pollutants (PAHs and OPPs) in Caspian Sea Coast-IranChangiz MohammadizadehPAHs form one of the most important classes of persistent pollutants. Sediment samples were taken from the eastern Caspian Sea coast of Mazandaran state analyzed by (GC-MS) for PAHs. Sediment samples were collected from eastern part of southern Caspian Sea in Mazandaran Province. Stations were Amirabad (10), Sari (5), Babolsar (5) and Noushahr (5) to determinate distribution and to source … …Current Research in Geoscience, Vol. 3, Issue 2 · 10 Jun 2014 · 6,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractDESIGN OF CANDIDA ANTARCTICA LIPASE B THERMOSTABILITY IMPROVEMENT BY INTRODUCING EXTRA DISULFIDE BOND INTO THE ENZYMEUsman Sumo Friend Tambunan, Ahmad Randy, Arli Aditya ParikesitCandida Antarctica Lipase B (CALB) is extensively studied in enzymatic production of biodiesel, pharmaceutical products, detergents and other chemicals. One drawback of using CALB is its relatively low optimum temperature at 313 K (40°C). The objective of this research is to design CALB mutant with improved thermostability by introducing extra disulfide bond. Molecular dynamic simulation was conducted to get better … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 18 Apr 2014 · 9,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTUDY OF PHYSICO-CHEMICAL PROPERTIES OF THE SURFACE AND GROUND WATERA.Y. Al-Ghamdi, Mohamed El-Shahate Ismaiel Saraya, A.O. Al-Ghamdi, S.A. ZabinOf all the natural resources, water is unarguably the most essential and precious. Life began in water and life is nurtured by water. Ninety seven percent of the world’s water is found in oceans. Only 2.5% of the world’s water are non-saline fresh water. Saudi Arabia is a desert country with no permanent rivers or lakes and very little rainfall. … …American Journal of Environmental Sciences, Vol. 10, Issue 3 · 18 Apr 2014 · 7,794 accessesView PDFCite
Research ArticleOpen accessIn the abstractBEHAVIOR OF THE NON-SELECTIVE HERBICIDE GLYPHOSATE IN AGRICULTURAL SOILAbdul Jabbar Al-Rajab, Othman M. HakamiGlyphosate [N-phosphonomethyl]glycine is a systematic, non-selective, organophosphorus herbicide used worldwide in agriculture and industrial zones. Following its application, residues of glyphosate can threaten soil or aquatic organisms in adjacent water. In this study, we followed the degradation, stabilization, remobilization and leaching of 14C-glyphosate in three agricultural soils in laboratory incubations and in lysimeters under field conditions. Glyphosate degradation was relatively … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 15 Mar 2014 · 9,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Cloning and Heterologous Expression of Human Interferon Alpha2b GeneI. Made Artika, Yemima Budirahardja, Anna Lucia EkowatiHuman alpha Interferons (hIFNα) have been shown to have antiviral, antiproliferative and immunomodulatory activities. The human interferon alpha2b (hIFNα2b), is one of the human interferon alpha2 sub variants, naturally synthesized as a polypeptide of 188 amino acid residues, the first 23 residues of which represents a signal peptide. In the present study, the hIFNα2b gene was expressed after being fused … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,840 accessesView PDFCite

Research ArticleOpen accessIn the abstractIdentification of Pharmacological Targets Combining Docking and Molecular Dynamics SimulationsIlizaliturri-Flores Ian, Rosas-Trigueros Jorge Luis, Carrillo-Vazquez Jonathan Pablo et al.Studies that include both experimental data and computational simulations (in silico) have increased in number because the techniques are complementary. In silico methodologies are currently an essential component of drug design; moreover, identification and optimization of the best ligand based on the structures of biomolecules are common scientific challenges. Geometric structural properties of biomolecules explain their behavior and interactions and … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 21 Mar 2013 · 8,130 accessesView PDFCite
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 · 7,720 accessesView PDFCite
