EditorialOpen accessIn the abstractRe-Paving the Road Built by Chemistry: A Challenge to Biochemistry and BiotechnologyAlberto A. IglesiasBiochemistry’s birth can be placed at the end of the nineteenth century, when Eduard Buchner made a clever interpretation of experimental observations on the generation of gas bubbles after addition (the original purpose was preservation) of sucrose to a yeast crude extract (Lagerkvist, 2005). Intelligently, Buchner concluded that the disaccharide had been fermented by broken cells’ suspension to produce CO2, … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 7,461 accessesView PDF Cite

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 906Â°C and 1564Â°C … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 26 Jul 2014 · 6,981 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNOVEL COLOR FILTER ARRAY DEMOSAICING IN FREQUENCY DOMAIN WITH SPATIAL REFINEMENTR. Niruban, T. Sree Renga Raja, T. Sree SharmilaThe main idea behind wavelet based demosaicing with spatial refinement is to reconstruct the full resolution color image from the mosaiced image. In this study, a new effective wavelet based demosaicing algorithm for interpolating the missing color components in Bayer’s Color Filter Array (CFA) pattern is proposed. This interpolation technique uses the interchannel correlation among the high frequency subbands to … …Journal of Computer Science, Vol. 10, Issue 8 · 9 Apr 2014 · 6,707 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCurrent and Future Nanotech Applications in the Oil IndustryCocuzza Matteo, Pirri Candido, Rocca Vera, Verga FrancescaProblem statement: Nanotech applications in the oil industry are not completely new: nanoparticles have been successfully used in drilling muds for the past 50 years. Only recently all the other key areas of the oil industry, such as exploration, primary and assisted production, monitoring, refining and distribution, are approaching nanotechnologies as the potential Philosopher's stone for facing critical issues related … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 13 Mar 2012 · 10,624 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOil Refineries Emissions Impact on Urban Localities Using AERMODAmira Mohamed Wahba Abdelrasoul, Amir AL-Hadad, Abdul Rehman KhanProblem statement: The absolute necessity of compulsory fuel utilities, no matter small or big has resulted into substantial high hazards pollutants. Petroleum refineries are major industrial installations that are necessary for providing the best suited fuel for various necessary utilities, but are responsible of the emission of several hazardous pollutants into the atmosphere. Hydrocarbons are among the most perilous air … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 7,729 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSpecialization of Recursive Predicates from Positive Examples OnlyMoussa DembaProblem statement: Given an overly general (definite) program P and its intended semantics Φ (the programmer’s intentions) where P does not satisfy Φ, find out a new version P’ of P such that P’ satisfies Φ. Approach: We proposed an approach for correcting overly general programs from positive examples by exploiting program synthesis techniques. The synthesized program, P’, is a … …Journal of Computer Science, Vol. 6, Issue 6 · 30 Jun 2010 · 6,854 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTowards the Decline and fall of Radical and Educational Constructivism (Mark I)James Carifio, Rocco J. PerlaProblem statement: In 1974, McKeachie published a brief article in The Educational Researcher called, &#34The Decline and Fall of the Laws of Learning&#34. Approach: This article was primarily about the decline and fall of the behaviorist laws of learning and radical behaviorism, both of which were never quite the same in psychology or education after this article as before it … …Current Research in Psychology, Vol. 1, Issue 1 · 1 Jan 2010 · 8,070 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Typical Case Study: Solid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanThe current environmental concerns have forced developed and developing countries to reduce air, water and land pollution for sustainable growth. Solid refinery waste is cocktail of hydrocarbons, water, heavy metal and fine solids and is substantial in quantity. The principal processes of waste management focus mainly on waste source reduction, reusing, recycling, composting, incineration with or without energy recovery, fuel … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 9,767 accessesView PDF Cite
