Research ArticleOpen accessIn the abstractESR and FT-IR Studies on GeO2 Substituted Lead Vanadate Semiconducting Glass SystemP. Tejeswara RaoA series of Germania-lead-vanadium pentoxide glasses with x=5, 10 and 15 mol% were prepared by melt quenching technique and they were characterized by X-ray diffraction (XRD), Differential scanning calorimetry (DSC), Fourier Transform Infrared (FT-IR) and Electron Spin Resonance (ESR) techniques. X-ray diffraction results reveal that all samples are perfect amorphous in nature. Differential scanning calorimetry results indicate that the substituent … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 19 Apr 2019 · 6,793 accessesView PDFCite
Research ArticleOpen accessIn the abstractTaxifolin Potently Diminishes Levels of Reactive Oxygen Species in Living Cells Possibly by Scavenging Peroxyl RadicalsSatoru Sakuma, Yui Kishiwaki, Mayu Matsumura et al.Taxifolin, a naturally occurring dihydroflavonol, has been reported to possess antioxidant activity, whereas there is little information regarding its antioxidant potency as a flavonoid. In the present study, the antioxidant efficacy of taxifolin in living cells was compared to that of catechin, a potent radical scavenger, by using flow cytometry with the redox-sensitive fluorescent dye, 2′,7′-dichlorodihydrofluorescein diacetate. Further, diminishing efficacy … …American Journal of Pharmacology and Toxicology, Vol. 13, Issue 1 · 18 Oct 2018 · 8,056 accessesView PDFCite
EditorialOpen accessIn the abstractInternational Journal of Structural Glass and Advanced Materials Research: A New Open Platform for Materials ScienceChiara Bedon, Mario D’Aniello, Andreas Luible, Flavio StochinoEditorial The International Journal of Structural Glass and Advanced Materials Research (IJSGAMR) is a new peer-reviewed, open access journal, which covers all aspects of theoretical and practical research of materials science. The journal aims to promote international exchange of knowledge and broad discussion on advancements, outcomes and recent developments in materials research for engineering applications. In the last years, the … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 1 · 17 May 2017 · 13,690 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Model for Resolving Flow Parameters for MRI-Neuroimaging ApplicationMoses E. Emetere, M.L. AkinyemiThe functionality of recent neuroimaging using the MRI machine has generated errors which are peculiar to all kinds of MRI processes. Though hardwares are used to complement the MRI process, the problems are not completely solved due to its fundamental errors. The fundamental error is in the exclusion of molecular interaction in the ab-initio Bloch NMR. A new mathematical concept … …American Journal of Applied Sciences, Vol. 12, Issue 9 · 29 Sep 2015 · 6,724 accessesView PDFCite
Research ArticleOpen accessIn the abstractMAY PARENTS INHERIT FROM HEIRS? TOWARDS AN UNDERSTANDING OF THE PARENT-SPUN-OFF RELATIONSHIPFederica Brunetta, Enzo PeruffoSpin-offs create financially and administratively stand-alone units that hold a strong affiliation with the parent firm due to the concurrence of the ownership structure. So far, few studies have adopted a process perspective to investigate on the value creation of spin off transactions. We argue that spin-off generation does not constitute firm failures, as parents have clear channels to appropriate … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 3 Apr 2014 · 7,075 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTRINGENT LIMITS FOR THE MAGNETIC FIELD FROM EARLY UNIVERSE DYNAMOS IN RF2 COSMOLOGY WITH TORSIONL. C. Garcia de AndradeBamba et al. (2012) have obtained cosmological magnetic fields in teleparallel torsion theories of gravity that are not compatible with galactic dynamos. This result agrees with previous ones obtained by the author which shows Garcia de Andrade (1999) that anti-dynamo generalised theorem to torsion theories forbides such kind of dynamos to explain galactic magnetic fields of the order of µG. … …Physics International, Vol. 5, Issue 1 · 27 Mar 2014 · 7,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Annealing Temperature on Characteristics of Bismuth Doped Zinc Oxide FilmsSirirat Tubsungnoen Rattanachan, Phanuwat Krongarrom, Thipwan FangsuwannarakIn this study, Bismuth (Bi) doped ZnO thin films were deposited on quartz substrates by a sol-gel spin coating method and annealed at different annealing temperatures of 200, 300, 400, 500, 600 and 700°C, respectively. Structural and optical properties of nanocrystalline Bi-doped ZnO film on quartz were investigated by using X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and UV-VIS spectrophotometer. … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 1 Oct 2013 · 7,126 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on Optical Constants and Refractive Index Dispersion of Neutral red Doped Polymer FilmHussain A. BadranProblem statement: The some optical constants polymer thin film with red dye 3-amino-7-dimethylamino-2-methyl phenazine (NR) as the guest material and Polyvinylpyrrolidone (PVP) as the host material were prepared by adulteration and spin-coating methods. Approach: The values of some important parameters (refractive index n, extinction coefficient K and dielectric constant ε∞) of polymer thin film are determined from these spectra. Results: … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 8,919 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Model Checkers' Input Languages for Modeling Traffic Light SystemsPathiah Abdul Samat, Abdullah Mohd Zin, Zarina ShukurProblem statement: Model checking is an automated verification technique that can be used for verifying properties of a system. A number of model checking systems have been developed over the last few years. However, there is no guideline that is available for selecting the most suitable model checker to be used to model a particular system. Approach: In this study, … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,887 accessesView PDFCite
