Research ArticleOpen accessAll words, across the recordLong-Term Characterization of Landfill Leachate: Impacts of the Tropical Climate on its CompositionJorge Luiz da Paixão Filho, Miriam Gonçalves MiguelThe disposal of Municipal Solid Waste (MSW) in sanitary landfills produces leachate, whose composition changes depending on the microbial community and the environmental conditions. However, these changes cannot be observed in sanitary landfill because of the superposition of cells, which makes it difficult to determinate the relationship among the phases of biodegradation of MSW, the composition of the leachate and … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 14 Mar 2017 · 8,573 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPhysicochemical Characteristics and Sub Chronic Oral Toxicity of Pistacia lentiscus L. Vegetable Oil in RabbitsMaameri Zineb, Zouhir Djerrou, Sofiane Habibatni et al.Pistacia lentiscus vegetable oil is a well known natural product in Algerian traditional medicine. It is widely used in the treatment of back pain, respiratory problems and skin burns. The aim of this study was the determination of some physicochemical parameters and the investigation of sub-chronic oral toxicity of this fatty oil in rabbits. The physico-chemical parameters obtained for this … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 13 Jan 2016 · 7,466 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCharacterization of Solid Residues Obtained from Supercritical Ethanol Liquefaction of Swine ManureRui Li, Bo Zhang, Shuangning Xiu et al.Animal wastes are considered as renewable energy resources, which contain a great energy potential. For this study, swine manure was treated with supercritical ethanol within the reaction temperature range of 240-360°C to produce bio-oil, resulting in a significant amount of solid residues. Solid residues were characterized by using Fourier Transform Infrared (FT-IR), Scanning Electron Microscopic (SEM), surface area, elemental and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 15 Jul 2015 · 7,687 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDeposition and Characterization of CdS Nano Thin Film with Complexing Agent TriethanolamineK. Manikandan, C. Surendra Dilip, P. Mani, J. Joseph PrinceThe equimolar concentration thin films of Cadmium Sulfide (CdxSx) with the complexing agent TEA were deposited on a glass substrate by the SILAR technique. The crystalline nature with face centered cubic crystal system of the CdS films is determined from X-ray diffraction analysis. The broadened diffraction peaks indicated nano sized particles of the film materials. The surface morphology of the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 1 Jun 2015 · 8,419 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordISOLATION AND CHARACTERIZATION OF RHIZOBIA AND PLANT GROWTH-PROMOTING RHIZOBACTERIA AND THEIR EFFECTS ON GROWTH OF RICE SEEDLINGSK. Z. Tan, O. Radziah, M. S. Halimi et al.Biofertilizer is a relatively safer, environmentally friendly and cost-effective approach as an alternative to reduce chemical fertilizer usage. The selection of bacterial strains with multiple beneficial characteristics are important to maximize the effectiveness on the host plant. Due to aforementioned interest, several Plant Growth-Promoting Rhizobacterial (PGPR) and rhizobial strains were isolated from rice and legume roots, respectively, at four locations … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 15 Apr 2014 · 10,904 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordExtraction, Purification and Characterization of Fish Chymotrypsin: A ReviewLiang Zhou, Suzanne M. Budge, Abdel E. Ghaly et al.Problem statement: Solid fish waste is generated from the unwanted parts of fish including heads, tails, fins, frames, offal (guts, kidney and liver) and skin. It accounts for up to 80% of material from production of surimi, 66% from production of fillet and 27% from production of headed and gutted fish. Currently, fish wastes are disposed off in land-based waste … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 22 Sep 2011 · 10,585 accessesView PDFCite
