Research ArticleOpen accessIn the abstractPreparation of Magnetic Paper from Kenaf: Lumen Loading and in situ Synthesis MethodC. H. Chia, S. Zakaria, S. Ahamd et al.Magnetic papers have been successfully prepared from unbleached kenaf (hibiscus cannabinus) kraft pulps via the lumen loading and in situ synthesis process. The lumen loading method allows the magnetic fillers to be introduced into the lumen of fibres and at the same time leaving the external surfaces free from filler, resulting the better inter-fibre bonding and subsequently its papermaking properties … …American Journal of Applied Sciences, Vol. 3, Issue 3 · 31 Mar 2006 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation and Beneficiation of Feldspar from Arkosic Sandstone in South Jordan for Application in the Ceramic IndustryMousa GougazehThe main purpose of the present study was to investigate the beneficiation and upgrading processes of a Jordanian feldspar ores to be finally implemented in the ceramic industry. The experimental work was conducted to evaluate the role of particle size distribution, chemical composition, mineral content and the magnetic impurities (Fe2O3 +TiO2 contents). The beneficiation of the 500-45 μm fractions, which … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractReport on Mammalian Fossils of Chinji Formation, Dhulian, PakistanMuhammad Akbar Khan, Abdul Ghaffar, Zulfiqar Ali et al.Twenty mammalian fossil specimens of varying preservational state are described from the Chinji Formation of Dhulian, Pakistan. The remains described in this study are all teeth and represent the Proboscidea, Perissodactyla and Artiodactyla. All the dental specimens are new variants recorded here for the first time. Pliotriplopus dhulianensis is new to science having small size and absence of crista than … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 7,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractVegetation Dynamics in the Tafileh Woodlands of Southern JordanSaleh Al-Qura'nWoodland vegetation in the Tafileh highlands of southern Jordan was investigated and quantitatively surveyed to determine the patterns of vegetation dynamics associated with altitude and topography. Three tree species (Juniperus phoenicea L. (evergreen needle-leaved woodland resistant to cold), Pistacia atlantica Desf. and Quercus aegilps L. (cold-deciduos broad-leaved woodland) and five shrubs (Colutea istria Miller, Gomphocarpus sinaicus R. Br., Thymelaea hirsute … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,929 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Clay Nanocomposites by Chemical Reduction MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver Nanoparticles (Ag-NPs) have been synthesized by using chemical reduction method into the interlayer space of a Montmorillonite (MMT) as a solid support which is used to antibacterial application and polymer nanocomposites for fabrication of medical devices. Approach: AgNO3 and NaBH4 were used as a silver precursor and reducing agent, respectively. The properties of Ag/MMT nanocomposites were studied … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 8,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcophysiology of Chirostoma Jordani Pisces: Atherinopsidae. Habitat Characterization and Population Dynamics in a Periurban Lake (Xochimilco, México)Latournerié-Cervera José Román, Rangel-Nambo María Isabel, Alma Rosa Estrada-OrtegaChirostoma Jordani is an endemic species of the Mexican plateau, whose population, due to anthropogenic causes, has experienced a notable decrease from 2000 to the present, putting its permanence in its natural habitat at risk. Therefore, the objectives of this research were focused on evaluating the population dynamics of C. Jordani through its size and weight distributions and growth rate … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 23 Jan 2021 · 7,546 accessesView PDFCite
Research ArticleOpen accessIn the abstractDividend Maximization in the Cramer-Lundberg Model using Homotopy Analysis MethodJuma Kasozi, Fred Mayambala, Charles Wilson MaheraProblem statement: We used the Homotopy Analysis Method (HAM) to numerically compute the value function of the dividend payment in the basic insurance process. Approach: The process is a constant income stream from premiums which is subtracted a claim process of the Poisson type. Further, an allowance for payment of dividends to share holders was incorporated. Results: The case when … …Journal of Mathematics and Statistics, Vol. 7, Issue 1 · 31 Jan 2011 · 7,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractTone Question of Tree Based Context Clustering for Hidden Markov Model Based Thai Speech SynthesisSuphattharachai ChomphanProblem statement: In HMM-based Thai speech synthesis, tone is an important issue that brings about the intelligibility of the synthesized speech. Tone distortion resulted from imbalance of the training data should be appropriately treated. Approach: This study described an HMM-based speech synthesis system for Thai language. In the system, spectrum, pitch and state duration are modeled simultaneously in a unified … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,820 accessesView PDFCite
Research ArticleOpen accessIn the abstractNucleation and Crystal Growth Rates of Struvite in DTM Type Crystallizer with a Jet-Pump of Descending Suspension Flow in a Mixing ChamberJoanna Koralewska, Krzysztof Piotrowski, Boguslawa Wierzbowska, Andrzej MatyniaThe kinetic data concerning reaction-crystallization of struvite from diluted water solutions of Mg2+, NH4+ and PO43- ions in a continuous DTM-type liquid jet-pump crystallizer with internal circulation of suspension are presented and discussed. The measurements were performed with the assumption of minimal value of unit power of a jet-pump’s feeding stream, providing thus a minimal level of internal circulation intensity. … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,957 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalysis of Interregional Commodity FlowsWirach Hirun, Sompong SirisoponsilpProblem statement: Commodity Flow Survey (CFS) was launched to collect comprehensive freight flow data throughout the kingdom of Thailand.
