Research ArticleOpen accessEvery word in the titleBootstrap Approach to Correlation Analysis of Two Mineral ComponentsT.O. OlatayoProblem statement: In this article we considered pairs bootstrap through a truncated geometric bootstrap method for stationary time series data. Construction of valid inferential procedures through the estimates of standard error, coefficient of variation and other measures of statistical precision such as bootstrap confidence interval were considered. The method was used to confirm the correlation between Silicon Oxide (SiO2) and … …Current Research in Geoscience, Vol. 2, Issue 1 · 7 May 2013 · 6,597 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleChronic Kidney Disease-Mineral Bone Disoder: Fibroblast Growth Factor-23 and Phosphate MetabolismWisit Cheungpasitporn, Pongsathorn Kue-A-Pai, Patompong Ungprasert et al.Chronic Kidney Disease (CKD) is a growing epidemic in the United States. There are hormonal changes that develop long before the mineral changes in patients with CKD occur. Increased Parathyroid Hormone (PTH) levels first become evident when the estimated Glomerular Filtration Rate (eGFR) is below 60 mL/min/1.73m2. High serum phosphate stimulates the secretion of the Fibroblast Growth Factor 23 (FGF-23) … …Current Research in Medicine, Vol. 4, Issue 1 · 4 May 2013 · 6,882 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWeight of Evidence Allocates Mineral Depositional ZonesAbdullah A. Bokhari, Guang Dao HU, Rani FouadProblem statement: Yunnan province in general and Pulang area in particular is geological rich area which prevents field study in multi locations due to high risk outcrop. Approach: New technology such as Geographic Information System (GIS) and an ArcView extension module Arcweight of evidence (WofE) became very handy to provide safety for researchers and allow organization to control their budget. … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 6,986 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleArsenic Adsorption on Bauxite Mineral Using Batch Equilibrium TestFares Yahay Alshaebi, Wan Zuhairi Wan Yaacob, Abdul Rahim Samsudin, Esmail AlsabahiProblem statement: Study suggested a solution to remove arsenic contamination from contaminated water. Approach: Bauxite, which is a mineral, was proposed as natural remediation material used in this study. Bauxite was collected from Johor mining company in Teluk Ramunia, Johor Bharu, Malaysia. Batch equilibrium test was performed in accordance to different initial concentrations, shaking time and different initial pH values. … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 6,838 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Computational Optimized Extended Model for Mineral Potential Mapping Based on WofE MethodZiaii Mansour, Pouyan Ali, Ziaei MahdiThe multivariate fuzzy-c-means classifier is used to model extended weight of evidence (WofE) considering predictor maps. Approaches to mineral potential mapping based on WofE modeling generally use binary maps, whereas, real-world geospatial data are mostly multi-class or fuzzy-class in nature. The consequent reclassification of fuzzy-class maps into binary maps is a simplification that might result in a loss of information. … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,571 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRed-Cell Trace Minerals in Children with AutismJoan Jory, Woody R. McGinnisAbnormalities in mineral-dependent antioxidant enzymes in children with autism raise interest in the determination of trace mineral status in this population. A cross sectional investigation of red cell mineral levels was carried out among 20 children with autism and 15 controls. Children with autism demonstrated significantly lower red cell selenium (p<0.0006) and higher molybdenum (p<0.01) than the controls. There was … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 7,877 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimation of Naturally Modified Mineral Water Protection Activity Against Experimental InfectionsEdward Vladimir Krizhanovsky, Kwong Choong LimAn estimation of protective efficiency of naturally modified mineral water (BAE Synergy Liquid preparation) was performed on animals in models of flue and anthrax infections. The preparation exhibited a significant effect as a preventive and therapeutic agent at these infections. …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,877 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEFFECT OF LIMING AND FERTILIZER APPLICATION IN HEMIC AND SAPRIC OF TROPICAL PEAT: PHOSPHORUS MINERALIZATION, INFRA-RED SPECTROSCOPY AND MICROSCOPYAmeera Abdul Reeza, Aminuddin Hussin, Ahmad Husni Mohd Hanif, Mohd Aspollah Md. SukariThis study was conducted to investigate the changes in nutrient level P as well as in the structural and functional groups upon the decomposition of Hemic and Sapric peat material due to application of lime and fertilizers. The peat materials were left to decompose for 8 weeks under laboratory incubation and samples were taken for the determination of extractable P … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 31 Mar 2014 · 8,393 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntegrating Life Cycle Assessment and Other Tools for Ex Ante Integrated Sustainability Assessment in the Minerals IndustryDeborah J Shields, Gian Andrea Blengini, Slavko V. SolarProblem statement: The minerals industry is faced with choices beginning in the exploration phase and extending over the life cycle of mine. Firms examine the technical feasibility of alternative actions and typically rank them based on economic performance. Increasingly firms also consider alternatives' contribution to sustainable development. Approach: Sustainable decision making before investment (ex ante decisions) should incorporate a broad … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 10 Oct 2011 · 7,898 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMineralogy and Chemistry of Coronadite from Middle Cambrian Manganese Deposits at Wadi Dana, Southern JordanAhmad Al-Malabeh, Tayel El-HasanCoronadite was reported from the upper-most horizons of the Middle Cambrian sediments at two locations in Wadi Dana, central Wadi Araba and Jordan. The unit is composed of dolomite, limestone and shale. Geochemical investigations show appreciable variations in Mn, Pb, Fe, K and Ba contents in the coronadite between the two studied sites. Pb was found to increase downward in … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,551 accessesView PDFCite
