Research ArticleOpen accessEvery word in the titleA Comparative Analysis on the Physiological Effects of the Physical and Chemical Properties of the Trihalomethanes on Nutrient Levels, Oxidative Stress and Sterol Compositions of Leaf Oils in Solanum Lycopersicum CultivarsBabatunde C. Akande, Olalekan S. Fatoki, James P. Odendaal et al.Trihalomethane group of disinfection by-products was used to evaluate the magnitude of physiological changes induced on nutrient levels, oxidative stress and phytosterol content in two tomato cultivars. The tomato cultivars were grown as potted plants in a greenhouse and exposed to the varying concentrations of trihalomethanes and organochlorines via irrigation water for a period of 30 days. The concentration levels … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 11 May 2018 · 8,415 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleFactors Affecting Chemo-physical and Rheological Behaviour of Zr44-Ti11-Cu10-Ni10-Be25 Metal Glassy Alloy Supercooled LiquidsApicella Antonio, Aversa RaffaellaSegregation by selective cold crystallizations and glass transition changes in Zr44-Ti11-Cu10-Ni10-Be25 metal supercooled metastable liquid annealed at different temperatures have been theoretically correlated to melt viscosity modifications. Crystallization behavior has been found to be principally related to the high mobility and smaller Be, Cu and Ni atoms. Multiple exothermal peaks in isothermal DSC annealing’s have been observed in these bulk … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 25 Feb 2016 · 8,148 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleApplying the Holistic Approach to the Physical Sciences and Engineering SystemsJoseph Z. Ben-AsherThe holistic approach is applied to several examples from the field of physics, engineering and systems engineering and its benefits are demonstrated. In all examples a holistic picture is used and studied while ignoring the various details of the discussed problems. Optimal control and optimal estimation approachs are used in the engineering examples. The results show that the holistic approach … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 6,915 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleX-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 · 7,466 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titlePhysical Composition, Nutrients and Contaminants of Typical Waste Dumping SitesH. Meuser, K. S. Grewal, R. Anlauf et al.Problem statement: The composition of wastes is quite variable depending upon the generating source and mode of collection. Most of the material from the domestic activities will be organic in nature and contains essential plant nutrients, whereas the dumping material of commercial and industrial wastes usually contains appreciable amounts of heavy and potentially toxic metals and organic pollutants. Approach: Objective … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,761 accessesView PDF Cite
