Research ArticleOpen accessIn the abstractComposition Dependent Structural and Thermal Properties of SM2O3 Doped Zinc Fluoroborate GlassesSudha D. Kamath, Akshatha Wagh, M.P. AjithkumarGlasses based on Sm3+ doped zinc fluoroborate have been synthesized and characterized. Formation of glass has been investigated in the 30 ZnF2-20 TeO2-(50-x) B2O3-x Sm2O3 matrix. Fast quenching is required to prevent melt crystallization and adequate heat treatment to diminish thermal stress, which results in an efficient amorphous material. The Differential Scanning Calorimeter (DSC), Scanning Electron Microscopy (SEM), Energy Dispersive … …Energy Research Journal, Vol. 4, Issue 2 · 15 Jul 2014 · 7,244 accessesView PDFCite

Research ArticleOpen accessIn the abstractSTRESS; THE VULNERABILITY AND ASSOCIATION WITH DRIVING PERFORMANCEB. M.T. Shamsul, S. Khairunnisa, Y. G. Ng, M. Y. Irwan SyahSeveral factors may contribute to occurrence of road accidents which are human factors, vehicle factor, road factor and environmental factor. There has been recent evidence of a relationship between road accidents and emotional distress as well as fatigue. Monotonous and complex road environments are the road factor that relates to the internal factor within driver. The overall aim of this … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 11 Jan 2014 · 7,717 accessesView PDFCite
Research ArticleOpen accessIn the abstractSYNERGY OF A NOVEL ANTIBIOTIC ADJUVANT ENTITY AGAINST MULTI DRUG RESISTANT ENTEROBACTERIACEAEManu Chaudhary, Anurag PayasiIn the present investigation, we investigated the in vitro interaction of ceftriaxone plus sulbactam with disodium edetate, a Non Antibiotic Adjuvant (NAA) against selected clinical isolates and in vitro susceptibility studies were also performed. The isolates were tested against a range of ratios of ceftriaxone and sulbactam using a microdilution checkerboard method. Having determined the appropriate ratios of ceftriaxone plus … …American Journal of Infectious Diseases, Vol. 9, Issue 3 · 1 Nov 2013 · 7,416 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolygalacturonase and Pectin Methylesterase Activities of CaCl2 Treated Red-Fleshed Dragon Fruit (Hylocereus polyrhizus) Harvested at Different MaturityY. B. Awang, S. H. Chuni, M. T.M. Mohamed et al.Fruits harvested at different maturity possess different biochemical constituents and physiological properties that make the fruits may react somewhat differently to the postharvest treatment. A study to examine the activity of Polygalacturonase (PG) and Pectin Methylesterase (PME) enzymes during storage in dragon fruit (Hylocereus polyrhizus) harvested at 28 days (Index 3) and 34 days (Index 5) after anthesis and postharvest … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 23 Jul 2013 · 8,433 accessesView PDFCite
Research ArticleOpen accessIn the abstractX-RAYS LUMINESCENCE, OPTICAL AND PHYSICAL STUDIES OF BI2O3-B2O3-SM2O3 GLASSES SYSTEMS. Rakpanich, J. Kaewkhao, N. Srisittipokakun et al.Sm3+-doped bismuth borate glasses of the composition (50-x) SiO2: 50B2O3: xSm2O3 (where x = 0.00, 0.50, 1.00, 1.50, 2.00 and 2.50 mol%) have been synthesized by conventional melt quenching technique. In order to understand the role of Sm2O3 in bismuth borate glasses, the density, molar volume, refractive index and optical absorption were investigated. The results show that density, molar volume … …Physics International, Vol. 4, Issue 1 · 18 Jul 2013 · 7,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Industrial Pollution on the Spatial Variation of Surface Water QualityIslam Mir Sujaul, Mohammed Amjed Hossain, Mohamad Ali Nasly, Md Abdus SobahanSurface water quality deterioration is the impact of anthropogenic activities at the study areas due to rapid industrialization.
