Research ArticleOpen accessIn the abstractUpgrading of Bio-Oil into High-Value Hydrocarbons via HydrodeoxygenationMurni M. Ahmad, M. Fitrir R. Nordin, M. Tazli AzizanProblem statement: World energy consumption is forecasted to grow significantly for the foreseeable future with fossil fuel remains the governing energy source. The demand in the need to explore alternative fuel source was further triggered by the overwhelmingly inconsistent cost of gasoline. Bio-oil is an alternative energy source produced from pyrolysis of biomass. However it is undesirable as a ready … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodegradation and Recycling of Urban Solid WasteS. P. Gautam, P. S. Bundela, A. K. Pandey et al.Problem statement: Rapid urbanization and population growth are largely responsible for very high increasing rate of solid waste in the urban areas, its proper management and recycling is major problems of Municipal Corporation. The proposed study attempted to proper management, physicochemical analysis of Urban Solid Waste (USW) and its conversion to enriched compost by ecofriendly process. Approach: For this study, … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,103 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrowth of Bone Marrow Derived Osteoblast-Like Cells into Coral Implant Scaffold: Preliminary Study on Malaysian CoralK. A. AL-SalihiProblem statement: Biomaterial fabrication in Malaysia started as a consequence of the demand for cheaper implant materials. Various biomaterials have been developed utilizing local resources like Malaysian coral. Locally processed Malaysian coral need to be complemented with proper evaluation and testing including toxicology, biocompatibility, mechanical properties, physicochemical characterization and in vivo testing. The present study was carried out to assess … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 6,590 accessesView PDFCite
Research ArticleOpen accessIn the abstractCementation Analysis by Eddy Current MethodM. Zergoug, H. Oubouchou, N. AmimeurIncrease the hardness, the endurance and the life time of material can be realised by surface treatments and remetallings, the electromagnetic properties of steels depend on their composition, their microstructures and constraints applied. We can use the electric and magnetic parameters to evaluate their microstructure. The object of this work is the characterization of cementation by the non-destructive methods and … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,565 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Porous Nanoflake ZnO for Dye-Sensitized Solar Cell ApplicationH. Abdullah, N. P. Ariyanto, S. Shaari et al.Problem statement: Nano-scale porous ZnO with high surface area have been studied to enhance physicochemical and electrochemical properties of certain optoelectronic devices applications. Approach: ZnO porous structure consists of flake-shape particles was synthesized through pyrolitic reaction of hydrozincite as Chemical Bath Deposition (CBD) product. Flake-like particle perpendicularly lied on substrate was obtained after 24 hours deposition. After calcinations, cavities on … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,377 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractUpgrading of Light Dewaxed Oil through Hydrofinishing and Additives Blending for Producing Automatic Transmission FluidGamal Abdel-Nasser Gohar, Mohamed Sherif El-Gayar, Abd El-Moneim Ibrahim et al.Light dewaxed oil was produced through dewaxing process of the light waxy distillate raffinate of crude oil from Western Desert of Egypt using methyl ethyl ketone/toluene mixed solvent. Hydrofinishing process was used to remove the non-hydrocarbon constituents and to improve the physicochemical properties of the produced oils such as color, viscosity index, inhibition responses, oxidation and thermal stability. The operating … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Model for Bioaccumulation of Metals in Crassostrea virginica from Apalachicola Bay, FloridaDennis A. Apeti, Elijah Johnson, Larry RobinsonKinetics of bioaccumulation of the trace metals (Cd and Zn) by C. virginica were investigated in this study. A computer program, Oyster Bioaccumulation Model (OBM), was developed to simulate the accumulation of the metals from both dissolved (water column) and particulate (food) phases by C. virginica. The model is based on two main attributes: (1) the oyster biological characteristics such … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractCytotoxicity Studies of Superparamagnetic Iron Oxide Nanoparticles in Macrophage and Liver CellsAroonsri Priprem, Pramote Mahakunakorn, Chunpen Thomas, Ian ThomasSuperparamagnetic Iron Oxide Nanoparticles (SPIONs) prepared by simplified coprecipitation were attractive as MRI contrast agents and drug carriers which could internally be manipulated under the influence of an external magnetic field and also cancer treatment due to additional hyperthermia effects. Problem statement: Macrophage and liver cells are potentially exposed to internal SPIONs, thus used for this cytotoxic tests for safety … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 22 Jun 2011 · 11,624 accessesView PDFCite
