Research ArticleOpen accessIn the abstractDynamic Measurement of Copper (II) Ion Adsorption in Activated Carbon Fixed Bed ColumnsTanokkorn Banjonglaiad, Eric Croiset, Peter Silveston et al.Dynamic experiments were carried out on the adsorption of copper (II) ions in a laboratory packed bed of activated carbon. Both pulse and step change inputs were used. Measurements were reproducible and replicate measurements furnished nearly identical parameters for a heterogeneous model of the activated carbon bed assuming Langmuir adsorption isotherm. The initial concentration of copper (II) ion was 3 … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesalination of Saline Sludges Using Ion-Exchange Column with ZeoliteA.E. Ghaly, M. VermaA flushing process followed by a zeolite based ion-exchange process were developed for the treatment of saline sludges from oil and gas exploration sites. The particle size distribution of sludge sample indicated the presence of very fine sand and clay. The electrical conductivity of the sludge was 42.2 dS m-1 indicating very saline sludge and the Cation Exchange Capacity (CEC) … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractWaste Characterization in Steel Casting and Recycling Opportunities in EuropeSilvia Fiore, Maria Chiara Zanetti, Barbara RuffinoThe wastes coming from a steel foundry located in Italy, producing about 600,000 t/y of steel slabs, are considered in this work. The plant produces about 143,000 t/y of wastes, made of furnace and ladle slags (84%), pelletized dust (8%) and oxidised shaving (8%). The waste materials have been characterised by means of particle-size and chemical analyses, and some reuse/recycle … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 7,055 accessesView PDFCite
Research ArticleOpen accessIn the abstractNanoceramic Matrices: Biomedical ApplicationsWilli Paul, Chandra P. SharmaNatural bone consisted of calcium phosphate with nanometer-sized needle-like crystals of approximately 5-20 nm width by 60 nm length. Synthetic calcium phosphates and Bioglass are biocompatible and bioactive as they bond to bone and enhance bone tissue formation. This property is attributed to their similarity with the mineral phase of natural bone except its constituent particle size. Calcium phosphate ceramics … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,369 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 · 6,988 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacteristics of Lipoprotein Peak x Eluted from a Column with the Eluent of High-magnesium Ion Concentration in Lipoprotein Analysis Using the Cation-exchange ChromatographyYuji Hirowatari, Hiroshi Yoshida, Yutaka Ogura et al.The new lipoprotein analysis method using a cation-exchange chromatography, which contains a sulfopropyl-ligand column and two magnesium ion-containing eluents was previously reported. This method can separate serum lipoproteins on the column gel with a magnesium ion concentration gradient and high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL) and an unspecified lipoprotein peak are eluted in order from the column. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,477 accessesView PDFCite
Research ArticleOpen accessIn the abstractAlterations of HDL Subclasses in Different Lipid Levels of Men and WomenYuye Yang, Luchuan Yang, Mingde Fu et al.With the increase of plasma TG level, both in men and women, apoA-I concentrations of preβ1-HDL and HDL3a were significantly higher while HDL2a and HDL2b were significantly lower. Similarly, with the increase of plasma LDL-C level, apoA-Iconcentrations of preβ1-HDL, HDL3c(in men) and HDL3b were significantly higher while apoA-Iconcentrations of HDL2b were significantly lower. And with the decrease of plasma HDL-C, … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 9,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractField and Laboratory Suction- Soil Moisture Relationship of Unsaturated Residual SoilsBujang B.K. Huat, Faisal H. Ali, A. AbdullahSoils located above the groundwater table such as residual soils are generally unsaturated and possess negative pore-water pressures. A soil-water (moisture) characteristic curve (SWCC) that relates the water content of a soil to matric suction is an important relationship for the unsaturated soil mechanics. The SWCC essentially shows the ability of an unsaturated soil to retain water under various matric … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractZinc Composition and its Effect on Magnetic Properties of Nickel-Zinc Ferrite Prepared Via Sol-gel TechniqueLee Kean Chuan, Hasnah Mohd ZaidNickel-Zinc (Ni-Zn) ferrite (Ni1-xZnxFe2O4) with different Zinc composition (x = 0, 0.25, 0.50, 0.75 and 1.0) were prepared and synthesized by applying sol-gel technique and the morphological characterization is done by X-Ray Diffraction (XRD) and Field Emission Scanning Electron Microscope (FESEM) to confirm the formation of Ni-Zn ferrite nanoparticle and estimate the particle sizes. Magnetic study was also performed using … …American Journal of Applied Sciences, Vol. 15, Issue 2 · 8 Jan 2018 · 8,067 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEvaluation of a Dual-Purpose Chemical Applicator for Paddy FieldsMohammed Shu’aibu Abubakar, Desa Ahmad, Othman Jamarei et al.Problem statement: One of the major problems of rice production is the shortage of labor resulting from migration from rural to urban areas, making it very difficult to meet peak demands for paddy production. In most developing countries of Southeast Asia, agricultural mechanization of paddy field operation is mostly carried out using conventional machines. For example in rice production powerintensive … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,545 accessesView PDFCite
