Research ArticleOpen accessIn the abstractCo-Digestion of Palm Oil Mill Effluent and Refined Glycerin Wash Water for Chemical Oxygen Demand Removal and Methane ProductionA. Sulaiman, M. R. Zakaria, M. A. Hassan et al.Problem statement: Refined Glycerin Wash Water (RGWW) from the oleochemical industry contains high Chemical Oxygen Demand (COD) and requires proper treatment before disposal. Unfortunately the wash water also contains high concentration of sodium chloride (NaCl) that could cause inhibition to the normal biological treatment process. However, there is feasibility of co-digesting the RGWW and Palm Oil Mill Effluent (POME) for … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 7,936 accessesView PDFCite
Research ArticleOpen accessIn the abstractMNM1D: A Numerical Code for Colloid Transport in Porous Media: Implementation and ValidationTiziana Tosco, Rajandrea SethiProblem statement: Understanding the mechanisms that control the transport and fate of colloidal particles in subsurface environments is a crucial issue faced by several researchers in the last years. In many cases, natural colloids have been shown to play a major role in the spreading of strongly sorbing contaminants, while manufactured micro-and nanoparticles, which are nowadays widely spread in the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 8,291 accessesView PDFCite
Research ArticleOpen accessIn the abstractCadmium Induced Changes in Metabolic Function of Mitochondrial Isolated from Potato Tissue (Solanum tuberosum L.)Chagra Ali, Djebar Mohammed Réda, Rouabhi Rachid, Berrebbah HouriaProblem statement: Cadmium is highly toxic at low concentrations, but the mechanism of its toxicity is still not understood particularly at the cellular and subcellular level. Approach: In this study we examined the effects of cadmium on the oxidophosphorylation properties of mitochondria isolated from potatoes. Results: Cadmium strongly disturbed the respiratory metabolism of mitochondria isolated especially in the transfer of … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Aug 2009 · 7,838 accessesView PDFCite
Research ArticleOpen accessIn the abstractDurability Assessment of Cylinder Block for Two Stroke Free Piston Linear Engine using Random LoadingM. M. Rahman, A. K. Ariffin, S. Abdullah et al.This research presents the durability assessment of cylinder block for a two-stroke free piston engine using narrow band approach. The life prediction results are worthy for improving the component design at the very early developing stage. This approach is adequate for periodic loading, however, requires very large time records to accurately describe random loading processes. Fatigue damage in conventionally determined … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractPost Traumatic Meningitis in Neurosurgery DepartmentReza Malekpour-Afshar, Saeed Karamoozian, Hassan ShafeiProblem statement: Post-Traumatic Meningitis (PTM) is a serious complication followed trauma. It sounds to have different pattern and characteristics. The aim of the current study was to determine the characteristics and outcome of PTM in referral neurosurgery department in Iran. Approach: During 5 years period-2003-2008, all records from meningitis patients in neurosurgery department in the unique referral trauma center in … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 7,857 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Higher Sludge Recycling Rate on Anaerobic Treatment of Palm Oil Mill Effluent in a Semi-Commercial Closed Digester for Renewable EnergyAlawi Sulaiman, Zainuri Busu, Meisam Tabatabaei et al.Problem statement: A 500 m3 semi-commercial closed anaerobic digester was constructed for Palm Oil Mill Effluent (POME) treatment and methane gas capture for renewable energy. During the start-up operation period, the Volatile Fatty Acids (VFA) accumulation could not be controlled and caused instability on the system. Approach: A settling tank was installed and sludge was recycled as to provide a … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 9,210 accessesView PDFCite

In this research, we wanted to reveal the relationship of paternal age to schizophrenia. This cross-sectional study was done on 240 patients of schizophrenia … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Changes of Some Electrolytes after Two Months ActivityM. J. Pourvaghar, A. R. ShahsavarSome investigators have speculated that sodium chloride losses in sweat associated with net dehydration may lead to the observed hyponatremia after prolong strenuous exercise. The effects of altered hydration can influence athletes cognitively in addition to physically. In this research, rest alterations of sodium and potassium of blood serum have been investigated. The subjects were male students who have been … …Journal of Social Sciences, Vol. 4, Issue 4 · 31 Dec 2008 · 7,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradation of Corn Oil Wastes by Fenton Reaction and Under Mildly Basic Media in the Presence of Oxidants Assisted with Sun LightJosefina Vergara Sánchez, Susana Silva Martínez, Maria del Refugio Trejo HernándezThe degradation of water soluble corn oil wastes was carried out by Fenton reaction and also under mildly basic media in the presence of oxidants, such as hydrogen peroxide and persulfate, assisted with solar light. The degradation efficiency was obtained by analysis of chemical oxygen demand, carbon dioxide and gas chromatography. Over 90% of both chemical oxygen demand abatement and … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,979 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistillation and Microdiffusion Modifications for total Nh4f Quantification and 15N RecoveryGaius D. Eudoxie, Gregory A. GouveiaProblem statement: Applying 15N techniques to accurately determine the fate of fixed ammonium (NH4f) in the strongly and weakly held pools require modifications to existing methodologies.
