Research ArticleOpen accessIn the abstractBiocontrol of Botrytis allii Munn the Causal Agent of Neck Rot, the Post Harvest Disease in Onion, by use of a New Iranian Isolate of StreptomycesM. Jorjandi, G.H. Shahidi Bonjar, A. Baghizadeh et al.Problem statement: Soil actinomycetes particularly Streptomyces spp. have showed antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. Onion neck rot or gray mold caused by Botrytis allii have imposed economic post harvest damages to onion bulbs and decreased its storage durability and market value. Approach: To investigate for … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractMass Structure Deformation Monitoring using Low Cost Differential Global Positioning System DeviceRamin S. Azar, Helmi Z.M. ShafriIn this study, a technique for monitoring bridge deformation with the simplest GPS device available was demonstrated. The accuracy of these observations was evaluated and the best approach for this purpose was suggested. The device used was the low cost GS20 Leica single frequency GPS, which is a basic GPS receiver for this study. This study was done during March, … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 8,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractFostering ICT Development for Growth: Measuring the Payoffs for Australia and the Asean-5 CountriesMudiarasan Kuppusamy, Mosayeb Pahlavani, Ali Salman SalehOver the past few decades the brisk development of information and communication technologies (ICT) has had a phenomenal impact on the economic stability and development of many countries. Empirical studies show that most developed economies have gained significant payoffs (in terms of economic growth) from their ICT investments. This study investigates the hypothesis that ICT-based investment has paid off for … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Certain Tetracyclines and Oxytetracyclines through Charge Transfer ComplexationKhairi M.S. FahelelbomProblem statement: Several studies were carried out to develop and validate a simple, rapid and accurate spectrophotometric method for the analysis of tetracycline (TC) and oxytetracycline (OTC) in the pure form and in pharmaceutical dosage forms, despite the varieties of these analytical techniques, the literature revealed that no spectrophotometric method for determination of tetracycline and oxytetracycline using charge transfer complexation … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 3 · 30 Sep 2008 · 8,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractResonance in Satellite's Motion Under Air DragRashmi Bhardwaj, Mani SethiThis article studies the attitude motion of a satellite in a circular orbit under the influence of central body of mass M and its moon of mass m, whose orbit is assumed to be circular and coplanar with the orbit of the satellite. The body is assumed to be tri-axial body with principal moments of inertia A < B < … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 7,003 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecreational Viagra Use and Sexual Risk among Drug Abusing MenDennis G. Fisher, Robert Malow, Rhonda Rosenberg et al.Until recently, the Viagra connection to HIV was anchored in older adults. However, CDC investigation showed stability in 50+ HIV diagnoses on the heels of upward trends in risk indicators among men who have sex with men (MSM) and substance abusing populations. Signs have increasingly pointed to recreational drug use among younger populations, to which Viagra is being added to … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 10,610 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMolecular Dynamics Studies of Human β-GlucuronidaseIbrahim Ali Noorbatcha, Ayesha Masrur Khan, Hamzah Mohd SallehProblem statement: The enzyme β-glucuronidase is being used as a reporter molecule in the area of genetic engineering, as a component of prodrug therapy in cancer treatment and in the scouring process of cotton fabrics. However, a detailed understanding of the factors responsible for the stability and the activity of this enzyme is still not available. Molecular Dynamics (MD) simulations … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,619 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInvestigating the Critical Clearing Time of Power System with the Exact Medium Transmission Line ModelPrechanon KumkratugProblem statement: The exact medium transmission line model consists of the resistance, series reactance and shunt capacitance. Most of previous research studies show the critical clearing time of single machine infinite bus while neglecting the resistance and capacitance of the line. Approach: This study investigates the critical clearing time of power system with consideration the exact medium transmission line mode. … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 23 Jan 2012 · 7,420 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordIntracellular 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 · 7,484 accessesView PDFCite
