Case ReportOpen accessIn the abstractOutlook of Municipal Solid Waste in Bogota (Colombia)José Alejandro Martínez SepúlvedaThe Municipal Solid Waste is a new target of the municipal government because their negative consequences if the management is inadequate (health diseases, pollution, etc.); In Latin America, the most frequency solution is the final disposal in landfill, but, no-all the Solid Waste is really waste (or unusable material): (i) The Inorganic Fraction that, for the no source separation, lost … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 2 Mar 2016 · 9,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Expediency of the Preliminary Heat Treatment for Liquid-Phase Reduction of Waste Steelmaking SlagEvgeny Trofimov, Ilya Chumanov, Andrey Dildin, Olga SamoylovaThe problem of using waste steelmaking slags as a technogenic source of metallurgical raw materials still has no sustainable solution and requires innovative ideas and approaches. The purpose of this paper is a theoretical and experimental study of the possibility and expediency of the preliminary heat treatment of steelmaking slags in a reducing medium for greater metal recovery. The subject … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 26 Nov 2015 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Mercury and Manganese by Using New Reagent Azo after Cloud Point Extraction for Some Environmental Sample in IraqSaadiyah Ahmed DhahirA new reagent of Azo was papered for determination of Hg+2 and Mn+2 by Cloud Point Extraction (CPE) method. Procedure which was developed for the separation and preconcentration and the procedure are simple, cheap, fast and environmental safety. The parameters affecting could point extraction, such as concentrations of reagent, volume of triton X-100, pH, equilibrium of temperature and time-consuming were … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 19 Nov 2015 · 6,971 accessesView PDFCite
EditorialOpen accessIn the abstractThe Proton Radius PuzzleG. M. HuberOccasionally,“revolutions” are caused in physics when new measurement techniques becomeavailable and cause us to rethink what we thought we knew. This has recently happenedin the field of proton structure physics, where researchers have had to revisitfundamental assumptions used in their determinations of the proton's meanelectric charge radius. Until 2010, ourknowledge of the proton's electric charge radius came exclusively fromelectron-proton interactions. … …Physics International, Vol. 6, Issue 1 · 12 Sep 2015 · 8,321 accessesView PDFCite
Research ArticleOpen accessIn the abstractProcess Intensification for Production and Recovery of Biological ProductsHamideh Vaghari, Maryam Eskandari, Vahideh Sobhani et al.Bioprocesses are important biological reactions which need several sophisticated methods and equipment to produce many novel and important compounds which some of them are traditionally produced by synthetic chemical reactions. In bioprocesses, the products are often produced in a dilute environment and finally they require a high purity. Because of that, downstream processes are usually included a large number of … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 29 Jan 2015 · 8,124 accessesView PDFCite

Research ArticleOpen accessIn the abstractA NEW THERMAL PROCESS FOR THE RECOVERY OF METALS FROM ZINC-CARBON AND ALKALINE SPENT BATTERIESGirolamo Belardi, Roberto Lavecchia, Franco Medici et al.The aim of this study is the thermal recovery of manganese and zinc from a mixture of zinc-carbon and alkaline spent batteries containing 40.9% of Mn and 30.1% of Zn after a preliminary physical treatment. Separation of the metals is carried out on the basis of their different phase change temperatures, the boiling point of zinc being 906°C and 1564°C … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 26 Jul 2014 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractLIPASE-CATALYZED TRANSESTERIFICATION OF PALM KERNEL OIL WITH DIALKYLCARBONATESTjahjono Herawan, M. Rüsch Gen. KlaasLipase-catalyzed transesterifications-especially in a solvent-free medium-are important for industrial applications because such systems would have an enormous advantage by avoiding the problem of separation, toxicity and flammability of organic solvents. However, the organic solvent-free alcoholysis, especially methanolysis, does not give high conversions. The same problem also occurs when ethyl or methyl acetate are used as acyl acceptors. The main problems … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 6 May 2014 · 6,793 accessesView PDFCite
