Research ArticleOpen accessIn the abstractPhenanthrene Contaminated Soil Biotreatment Using Slurry Phase BioreactorM. Arbabi, M. Sadeghi, Ch. AnyakoraProblem Statement: Polycyclic Aromatic Hydrocarbons (PAHs) are suspected toxins that accumulate in soils and sediments due to their insolubility in water and lack of volatility. Slurry-phase biological treatment is one of the innovative technologies that involve the controlled treatment of excavated soil in a bioreactor. Due to highly soil contamination from petroleum compounds in crude oil extraction and also oil … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Production Process of Biological Mineral Feed AdditivesAgnieszka Zielińska, Katarzyna Chojnacka, Marjana SimoničProblem statement: This study discussed the problem of accumulation of Zn and Cu in the topsoil as a result of application of mineral feed additives that possess low bioavailability in animal diet. The review considered the production process of mineral feed additives in which a product supplies microelements in highly bioavailable form. Enrichment of natural biomass of edible microalgae with … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Fuzzy Logic Control with Input Shaping for Input Tracking and Sway Suppression of a Gantry Crane SystemM. A. Ahmad, Z. MohamedProblem statement: Most of the common gantry crane results in a sway motion when transporting the load as fast as possible. In addition, precise cart position control of gantry crane must required a zero or near zero residual sway. Approach: In this study, the development of hybrid control schemes for input tracking and anti-sway control of a gantry crane system … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Manufacturing Stresses to Die Attach Film Performance In Quad Flatpack No-Lead Stacked Die PackagesM. F. Rosle, I. Abdullah, S. Abdullah et al.Problem statement: Repeated heat cure during assembly processes affected the Die Attach Film (DAF) material properties and the effectiveness touched area that leads to weak die bonding and delamination. Suitable die attached condition and DAF material selection had been evaluated to achieve required reliability performance in the manufacturing of the 3D Quad Flat No-Lead (QFN) stacked die package. Approach: During … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,054 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization and Wash Performance Analysis of Microbial Extracellular Enzymes from East Calcutta Wetland in IndiaRamesh Malathu, Sanhita Chowdhury, Madhusmita Mishra et al.Extracellular protease from a novel bacterial isolate showing maximum similarity of 98.22% with Microbacterium luteolum was obtained from East Calcutta Wetland, India. It showed compatibility with commercial detergents. The enzyme retains more than 60% of its activity between 6.0 to 10.5 pH. The maximum activity is at pH 7.5 with 71% activity at pH 10.0 and 10.5. The protease retained … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 8,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Grazing Sorghum Stubble on Soil Physical Properties and Subsequent Crop PerformanceB.J. Radford, D.F. Yule, M. Braunack, C. PlayfordTwo grazing trials were conducted on a Vertosol in central Queensland to assess the effects of stubble grazing by cattle on soil properties and subsequent crop performance. Two adjacent contour bays were selected for two treatments (grazed and ungrazed) in each trial. Both trials were conducted following a grain sorghum crop. In trial 1 (during 1996) the surface soil was … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,157 accessesView PDFCite
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 abstractEnhancing P300 Component by Spectral Power Ratio Principal Components for a Single Trial Brain-Computer InterfaceS. Andrews, Ramaswamy Palaniappan, Andrew Teoh, Loo chu KiongHere we present a novel approach to detect P300 wave in single trial Visual Event Related Potential (VERP) signals using improved principal component analysis to enable a faster brain-computer interface (BCI) design. In the process, the principal components (PCs) are selected using novel methods, namely spectral power ratio (SPR) and sandwich spectral power ratio (SSPR). We set out to assess … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,884 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrength and Ductility of Randomly Distributed Palm Fibers Reinforced Silty-Sand SoilsS.M. Marandi, M.H. Bagheripour, R. Rahgozar, H. ZareThis paper investigates the resultant strength and ductility behavior when randomly distributed palm fibers are used to reinforce silty-sand soils. The composite soils were tested under laboratory conditions and examined for unconfined compression strength (UCS), California Bearing Ratio (CBR) and compaction test. The results indicated that; the maximum and residual strengths, orientation of surface failures, ductility and the stress-strain relationship … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,864 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlasmid-mediated Detoxification of Mycotoxin Zearalenone in Pseudomonas Sp. ZEA-1Abdullah D. AltalhiThe Pseudomonas sp. Strain ZEA-1 was isolated from rhizosphere of corn plant by an enrichment technique showed capability of utilizing zearalenone as the sole source of carbon. The bacterium rapidly utilized zearalenone beyond 200 µg/ml and showed prolific growth in a minimal medium containing 100 µg/ml zearalenone source.
