Research ArticleOpen accessIn the abstractGeochemical Distribution of Trace Metals and Assessment of Anthropogenic Pollution in Sediments of Old Nakagawa River, Tokyo, JapanH.M. Zakir, Naotatsu Shikazono, Kazuo OtomoThe geochemical distributions of cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn) were examined in sediments collected from Old Nakagawa River (NR), Tokyo, Japan. A widely used 5-step sequential extraction procedure was employed for the fractionation of the metals and the concentrations were measured in the liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS). The association … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement ProductionMohd Sobri Idris, Khairul Nizar Ismail, Shamsul Baharin Jamaludin et al.Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of microstructure shows that the formation of belite minerals started at temperature nearly 1200°C which is at calcinations zone temperature, followed by formation of α±-belite at higher temperature (around 1300°C), then … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,498 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Selenium-Enriched Yeast (Kluyveromyces marxianus) Biomass in a whey-based Culture MediumNicolás Gurdo, Mario Calafat, Diego Gabriel Noseda, Isabel GigliTwo important aspects of agriculture intensification are the reduction in the concentration of specific soil minerals that affects livestock production and the increase of agricultural by-products, which produce environmental pollution. In this regard, whey - a cheese by-product-often is considered a wasted-product. Due to its lactose concentration, (4.5%), when whey is discarded without treatment generates a high Biological Oxygen Demand … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 28 Jun 2018 · 11,375 accessesView PDFCite
Research ArticleOpen accessIn the abstractOccupational Safety and Health in Tunnelling in Rocks Formations Potentially Containing Asbestos: Good Practices for Risk Assessment and ManagementDavide Labagnara, Mario Patrucco, Achille SorliniIn tunnelling operations, Occupational Safety and Health (OS&H) and Environmental Protection of the areas close to the tunnel portal become even more critical in case of rock formations potentially containing asbestos, quartz, radioactive elements, etc. In order to limit the workers’ exposure and the environmental impact becomes in these cases of paramount importance to preliminarily analyze and quantify the possible … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 26 May 2016 · 7,646 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch of the Interacting Process of Copper-Base Alloys with Leaching Solutions under the Action of Different Physicochemical FactorsBagdaulet Kenzalyevich Kenzhaliyev, Ainur Nurkalyevna Berkinbayeva, Rustam Hasanovich SharipovAnalysis of the current scientific and technical data shows the increased difficulty in innovative solutions development for metal extraction from different kinds of mineral raw materials, due to fundamental change in mineral resources base of metallurgy. Apart from polymetallic ores, complex in chemistry and intractable, the basis for the current mineral resources base is formed by technogenic production waste, so-called … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 2 Dec 2015 · 6,708 accessesView PDFCite
Research ArticleOpen accessIn the abstractSIMULTANEOUS OPTIMISATION OF DRYING PARAMETERS OF CERAMIC BODIESSalah Mahmoudi, Ezzeddine Srasra, Fouad ZargouniThis study deals with the mineralogical, physico-chemical and geotechnical analyses of representative Aptian clays in the north-east of Tunisia. X-ray diffraction reveals a predominance of illite (50-60 wt.%) associated to kaolinite and interstratified illite/smectite. The accessory minerals detected in raw materials are quartz, calcite and Na-feldspar. The average amounts of silica, alumina and alkalis are 52, 20 and 3.5 wt.%, … …Current Research in Geoscience, Vol. 4, Issue 1 · 1 Jul 2014 · 6,991 accessesView PDFCite
Research ArticleOpen accessIn the abstractMORINGA TEA BLOCKS ACUTE LUNG INFLAMMATION INDUCED BY SWINE CONFINEMENT DUST THROUGH A MECHANISM INVOLVING TNF-α EXPRESSION, C-JUN N-TERMINAL KINASE ACTIVATION AND NEUTROPHIL REGULATIONMykea Mcknight, Jabria Allen, Jenora T. Waterman et al.Plant based products represent a promising alternative to conventional treatments for inflammation. Moringa oleifera Lam is a tree rich in proteins, vitamins, minerals and a variety of phytochemcals with health benefits. Among the reported health benefits are antioxidant and anti-inflammatory properties. The purpose of this study was to investigate whether tea brewed from dried Moringa leaves would abrogate inflammation in … …American Journal of Immunology, Vol. 10, Issue 2 · 8 May 2014 · 11,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractBIOCHEMICAL STUDIES ON NIGERIAN MONODORA TENUIFOLIA SEEDEkeanyanwu Raphael Chukwuma, Njoku Obioma UzomaThe nutritive constituents of the seeds of Monodora tenuifolia were analyzed to augment the available information on Monodora tenuifolia research. Blood glucose and lipid profile were investigated on the flavonoid rich fraction of M. tenuifolia in rats. The composition (gkg-1) of alkaloids, cyanogenic glycosides, tannins and flavonoids were 13.3±0.1, 21.2×10-2±0.6, 1.3±0.1, 1.7±0.1 and 11.7±1.1 respectively. The proximate composition (gkg-1) of … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 30 Sep 2013 · 7,572 accessesView PDFCite
