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 · 6,589 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleHead-Space Solid Phase Micro-extraction Followed by GC/MS Analysis of the Volatile Components in Seeds of Cinnamonum camphoraYang Yong, Tao WenyiThe volatile components in seeds of Cinnamomum camphora were analyzed by Solid Phase Micro-extraction (SPME) combined with GC/MS. Twenty four main kinds of volatile compounds, among which the Sesquiterpene (29%), 3-Hexen-2-one (25%) and Monoterpene (10.22%), were separated and analyzed. …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,382 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetermination and Source Apportionment of Selected Heavy Metals in Aerosol Samples Collected from SebeleAlfred Sello Likuku, Gilbert Kabelo Gaboutloeloe, Khumoetsile B. MmolawaBush fires and dust in the dry winter months establish moderately high background levels of aerosols. Emissions into the atmosphere by copper mines, coal mines and vehicular emissions are all possible sources of air pollution with heavy metals. Although there has been assessment and monitoring of heavy metals and their air pollution in other countries such as Brazil, Europe and … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 25 Apr 2013 · 7,441 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGenetic Variability in Rhizoctonia solani Isolated from Vitis vinifera Based on Amplified Fragment Length PolymorphismAmparo Meza-Moller, Martin Esqueda, Felipe Sanchez-Teyer et al.Problem statement: Rhizoctonia solani is a potential grapevine pathogen. In order to develop effective methods of control, it is necessary to document its genetic diversity. Approach: The objective of this study was to analyze the genetic variability of R. solani isolated from the rhizosphere of ungrafted V. vinifera var. perlette seedless planted in Sonora, Mexico using Amplified Fragment Length Polymorphism … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 8,477 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPredicting Insurance Investment: A Factor Analytic ApproachSamuel Obi-Nnamdi Agwuegbo, Adetunji Philip Adewole, A. N. MaduegbunaProblem statement: In the last decade growing attention has been paid to the pattern of investments by the insurance industry and the question of how to evaluate such investments. In an economy where the capital market is huge and active, mathematical considerations come into play in the selection of investments to ensure yield maximisation.

Research ArticleOpen accessIn the keywordsStroke Motion Learning for a Humanoid Robotic Ping-Pong Player Using a Novel Motion Capture SystemC. H. Lai, T.I. James TsayProblem statement: Human ping-pong players determine the stroke trajectory according to their experience before the ball enters their court. However, to enable a humanoid robot to select the appropriate stroke motion based on skills learned from 3D motion, important patterns must be generated to simplify the complex 3D motion. Approach: This study developed an effective strategy for teaching ping-pong skills … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFactor Analysis, Target Factor Testing and Model Designing of Aromatic Solvent Effect of the Formyl Proton Nuclear Magnetic Resonance Chemical Shift in Para substituted BenzaldehydesGhazwan F. FadhilProblem statement: The variations of formyl proton Chemical Shifts (CS) of p-substituted benzaldehydes in aromatic solvents were investigated. The validity of several physical solvent and empirical solvent scales was examined. Also, to predict dipolarity-polarizability (π*) solvent scale for some aromatic solvents. Model designing was also achieved to rationalize the aromatic solvent effect on the formyl proton CS. Approach: The previously … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,582 accessesView PDFCite
