Research ArticleOpen accessIn the abstractFoundry Wastes Reuse and Recycling in Concrete ProductionSilvia Fiore, Maria Chiara ZanettiThe industrial process of a cast iron foundry plant located in the North of Italy was analyzed in order to determine the amount and kind of produced wastes. The main fractions are core and moulding sands, muds and powders from dust abatement plants, furnace and ladle slags, and exhaust lime, making about 750-800 t/d of residues for a production of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Profile of Some Heavy Metal Ions Adsorption Onto Biomaterial SurfacesMedhat A. ShakerThe adsorption of Co2+, Zn2+, Pb2+ and Hg2+ onto dried non-living biomass (NB) of different Pseudomonas strains has been investigated in detail. Maximum adsorption of these cations is achieved at optimum pH values from 3.5 to 4.5 to avoid hydrolysis, polymerization and precipitation of metal cations in the treatment solutions. The experimental data obtained at different temperatures were fitted to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,881 accessesView PDFCite

Research ArticleOpen accessIn the abstractOptical Properties and Sugar Content Determination of Commercial Carbonated Drinks using Surface Plasmon ResonanceW. Y.W. Yusmawati, H. P. Chuah, M. Y.W. MahmoodIn this study, an optical sensor based on Kretschmann SPR technique was used to detect the sugar content in commercial carbonated drinks. Three samples of carbonated drinks labeled as "Coke", "100 Plus" and "F&N Orange" have been chosen for angle scan SPR measurements. All the measurements were carried out at room temperature using He-Ne laser beam (632.8nm, 5mW) as a … …American Journal of Applied Sciences, Vol. 4, Issue 1 · 31 Jan 2007 · 8,786 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-objective Genetic Algorithm for Association Rule Mining Using a Homogeneous Dedicated Cluster of WorkstationsS. Dehuri, A. K. Jagadev, A. Ghosh, R. MallThis study presents a fast and scalable multi-objective association rule mining technique using genetic algorithm from large database. The objective functions such as confidence factor, comprehensibility and interestingness can be thought of as different objectives of our association rule-mining problem and is treated as the basic input to the genetic algorithm. The outcomes of our algorithm are the set of … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 7,525 accessesView PDFCite
