Research ArticleOpen accessIn the abstractEffects of Temperature and Flow Rates of Ozone Generator on the DBD by Varying Various Electrical ParametersBalakrishnan Anantharaman Poonamallie, Lakshminarayanan Vaduganathan, Mahendran NagalingamThis study rationale a high voltage power supply which varies of (O-5) kV with the variable frequency of 50 Hz-5 kHz. The power supply is used in the dielectric barrier discharge tube for the ionization process to yield concentration of ozone.This setup points the development of small and high efficient ozone generators using corona discharge method. Ozone generation was carried … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 6 Aug 2012 · 8,293 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 abstractMolecular 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 · 7,613 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradation of High Voltage Polymeric Insulators in Arid Desert's Simulated Environmental ConditionsYasin KhanProblem statement: High Voltage (HV) polymeric insulators are replacing ceramic insulator commonly used for HV outdoor networks due to their ease of handling, reliability and cost. However, their long term performance and reliability are major concerns to power utilities. Approach: To investigate their performance in arid desert's conditions, two types of HV composite insulators were aged as per International Electrochemical … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractChelation Study of Captopril with Cd2+ and Pb2+ IonsMohammad Joshaghani, M.B. Gholivand, A.R. MosavatThe protonation constants of Captopril, (1-(3-mercapto-2-(S)-methyl-1-oxopropyl)-S(L) proline, (CPL) and stabilities of its two divalent metal ions Cd(II) and Pb(II) were determined potentiometrically in two different metal to ligand ratio 1:1 and 1:2 systems and in water and methanol-water binary mixtures using the computer Best program. Two protonation constants were obtained which were assigned to the carboxylic and thiol groups. All … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 6,923 accessesView PDFCite
