Research ArticleOpen accessIn the abstractIntracellular L-Asparaginase from Bacillus sp. PG02: Purification, Biochemical Characterization and Evaluation of Optimum pH and TemperatureFatemeh Izadpanah Qeshmi, Mahsa Rahimzadeh, Sedigheh Javadpour, Manijeh PoodatBacterial L-asparaginases are amidohydrolases that act on L-asparagine and produce L-aspartate and ammonia. These enzymes have been used in treatment of lymphoblastic leukemia. In the present study, a novel strain, Bacillus sp. PG02 was explored for the production of intra-cellular L-asparaginase enzyme. The nitrogen source for L-asparaginase production was L-asparagine. New intracellular L-asparaginase was purified using ion exchange chromatography and … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 26 Nov 2015 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeficient Reasoning for Dark Matter in GalaxiesJames Q. Feng, C.F. GalloIn this universe, not all of the matter around us can be readily seen. The further an object is away from us and the less luminous it is, the less visible it becomes. Just by looking at an object is usually difficult, if not impossible, to tell the amount of mass it contains. But astronomers have been using the measured … …Physics International, Vol. 6, Issue 1 · 14 Sep 2015 · 8,285 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Review of Flood Risk Analysis in NigeriaAkinola Adesuji Komolafe, Suleiman Abdul-Azeez Adegboyega, Francis Omowonuola AkinluyiNigeria has witnessed diverse flood events in the past years and due to the high level of vulnerability and lack of coping capacity of the people, with the fast occurrence of extreme events resulting from climate change, many lives and properties are at risk of its impacts. This paper reviews the recent past and present efforts in assessing the flood … …American Journal of Environmental Sciences, Vol. 11, Issue 3 · 12 Sep 2015 · 10,800 accessesView PDFCite
Research ArticleOpen accessIn the abstractItalian Phrasemes as Constructions: How to Understand and Use ThemElmar SchafrothThe present article describes the objectives and methods for a learner-centered description of Italian idioms based on the theoretical principles of Construction Grammar (CxG). The aim of the underlying research project is to develop a new way of looking at idioms, taking into account all linguistic aspects that could help to fully understand and usethem in a formally and functionally … …Journal of Social Sciences, Vol. 11, Issue 3 · 3 Sep 2015 · 9,086 accessesView PDFCite
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 PDFCite
Research ArticleOpen accessIn the abstractEffect of Metalloid Compound and Bio-Solution Additives on Biodiesel Engine Performance and Exhaust EmissionsKaroon Fangsuwannarak, Kittichai TriratanasirichaiThe purpose of this study is to perform comparative analysis of the effect of the different fuel additives as polymer based-bio-solution, natural organic based-bio-solution and nano-titanium metalloid (TiO2) compound on the performance parameters and exhuast emissions of a pickup Diesel engine, operating on commercial Diesel fuel (D) and B5 palm biodiesel (95% D+5% palm oil). The basic properties of the … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 5 Sep 2013 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview of Energy Detection for Spectrum Sensing in Various Channels and its Performance for Cognitive Radio ApplicationsR. Suresh Babu, M. SuganthiSpectrum sensing is the basic and important operation in Cognitive Radio (CR) to find the unused spectrum. Energy detector is a popular sensing method because it doesn’t require transmitted signal properties, channel information, of even the type of modulation. This study summarizes the performance result of energy detector over Additive White Gaussian Noise (AWGN), Rayleigh fading and Nakagami fading channels. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 4 Aug 2012 · 7,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectronegativity, Interaction Parameter and Electronicpolarizability for Bisumth Borate Metal GlassesEl-Sayed Moustafa, Farid ElkhatebProblem statement: In the present work, we applied the concept of the optical electronegativity to predict basic properties of some ternary oxide glasses. Recently Optical electronegativity of many binary oxide glasses has been evaluated on the basis of two different parameters, the linear refractive index and the energy gap, which have demonstrated remarkable correlation. Approach: In this study, the refractive … …Physics International, Vol. 2, Issue 1 · 1 Dec 2011 · 7,312 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Recent Research and Implementation Methodologies on Medical Image SegmentationS. K. Somasundaram, P. AlliProblem statement: Image segmentation plays a very important role in digital imaging applications for classifying the anatomical structures and other Regions of Interest. Segmentation refers to the process of identifying and isolating the surface and regions of the digital image which corresponds to the structural units. Approach: In the past few decades, many methods have been proposed to segment the … …Journal of Computer Science, Vol. 8, Issue 1 · 4 Nov 2011 · 7,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractRule Based Shallow Parser for Arabic LanguageMona Ali Mohammed, Nazlia OmarProblem statement: One of language processing approaches that compute a basic analysis of sentence structure rather than attempting full syntactic analysis is shallow syntactic parsing. It is an analysis of a sentence which identifies the constituents (noun groups, verb groups, prepositional groups), but does not specify their internal structure, nor their role in the main sentence. The only technique used … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 7,183 accessesView PDFCite
