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

New nanotechnology industries, such as neural prothesis, are bringing nanomaterials in direct contact with neurons and glial cells. Nanomaterials have unique chemical and physical properties that may lead to toxicological effects by interfering with normal cellular metabolism. … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 2 · 4 Jul 2014 · 8,488 accessesView PDFCite
Research ArticleOpen accessIn the abstractBONE MEAL AS ALTERNATIVE TREATMENT FOR ACIDIC AND METAL CONTAMINATED ACID MINE DRAINAGE WATER EFFLUENT: LAB SCALECarolyn Payus, Olga David, Moh Pak YanThe typical methods of treatment for acidic and metal contaminated water effluent such as the Acid Mine Drainage (AMD) will always focus on either civil engineering methods, such as disposal, excavation, drainage and encapsulation or process based technologies such as effluent washing and treatment. These techniques are not environmental friendly, costly and unsustainable, thus environmental damaging. Nowadays, there is a … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 3 Mar 2014 · 7,979 accessesView PDFCite
Research ArticleOpen accessIn the abstractA BIOPHYSIOCHEMICAL ANALYSIS OF SETTLED LIVESTOCK AND POULTRY HOUSING DUSTSCarresse Gerald, Christi McPherson, Tha’Mes McDaniel et al.The levels and composition of agricultural dusts are influenced by animal species, production strategy, housing type and ventilation efficiency. Agricultural dust within animal houses is complex and consists of feed particles, microbes and their products, dander, fecal matter, gases, metals and other organic and inorganic components. Livestock and poultry production facilities may be categorized as confinement, semi-confinement or pasture-based. Characterization … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 16 Jan 2014 · 8,080 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHE STRUCTURE AND MECHANICAL PROPERTIES OF ALUMINA FILM PREPARED BY RF DIODE SPUTTERINGH. Panitchakan, P. LimsuwanAlumina (Al2O3) films were prepared on Al2O3-TiC substrates by RF diode sputtering. The target sputtering power was varied from 4 to 8 kW. The effects of target sputtering power on the structure and mechanical properties of alumina films were investigated. The results show that the structure of the alumina films deposited at all the target sputtering powers is amorphous. However, … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 6,897 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Mode of Action of Antibacterial Components from Melastoma malabathricum Linn LeavesMourouge Saadi Alwash, Nazlina Ibrahim, Wan Yaacob AhmadThe present study aimed to assess the antibacterial activity of the methanol extract of Melastoma Malabathricum Leaves (MMML), active fraction of M. Malabathricum Leaves (ML5) and isolated kaempferol-3-O-(2",6"-di-O-p-trans-coumaroyl)-β-glucopyranoside (Kf) and to describe the preliminary mode of action against Gram-positive and Gram-negative bacteria.
