Research ArticleOpen accessIn the abstractAlmost Graded Prime IdealsAmeer Jaber, Malik Bataineh, Hani KhashanProblem Statement: Graded commutative ring with unity over an abelian group were introduced by many authors such as T. Y. Lam and C. T. C. Wall, and almost prime ideals over commutative rings with unity were introduced by S.M. Batwadeker and P.K. Sharma, and this forced us to try to extend the theory of almost and n-almost prime ideals to … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,030 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerobic Biostabilization of Old MSW LandfillsM.C. ZanettiMany years after the end of the cultivation phase, landfills may generate intense odours, toxic and explosive gases and heavily-polluted leachate. A wide-spreading trend in the management of MSW landfills is represented by the forced aeration of wastes in order to achieve the stabilization, reducing the negative environmental impact of uncontrolled sites (old landfills which can be definitely considered as … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,233 accessesView PDFCite
Research ArticleOpen accessIn the abstractGait Optimization of Biped Robot during Double Support Phase by Pure Dynamic SynthesisNima Jamshidi, Mostafa RostamiThis paper deals with dynamic optimization of biped locomotion. The main focus of this research is motion optimization of double support phase. The optimization problem is dealt by using Pontryagins Maximum Principal. For motion optimization of double support phase, the closed kinematic chain has been considered to be opened at appropriate joint and the components of ground reaction forces has … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,127 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Typical Case Study: Solid Waste Management in Petroleum RefineriesJadea S. Alshammari, Fatma K. Gad, Ahmed A.M. Elgibaly, Abdul Rehman KhanThe current environmental concerns have forced developed and developing countries to reduce air, water and land pollution for sustainable growth. Solid refinery waste is cocktail of hydrocarbons, water, heavy metal and fine solids and is substantial in quantity. The principal processes of waste management focus mainly on waste source reduction, reusing, recycling, composting, incineration with or without energy recovery, fuel … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 9,767 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Behavior of A High Anchored Reinforced Earth WallFaisal Hj Ali, Bujang B.K. Huat, Lee Chee HaiSince the invention of Reinforced Earth by the French architect Hendri Vidal in 1966, numerous reinforced soil walls have been designed and constructed all over the world. In this study the focus was on a particular type of reinforced wall called Nehemiah wall which differed from the Vidal type in the sense that instead of steel strips, the reinforcing elements … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,258 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Earthquakes on Some Kind of BuildingsJ. Alberto Escobar S., J. Antonio Mendoza, Roberto Gómez M.A new method that simplifies the current static seismic torsion design procedure for buildings is proposed. Distribution of the shear forces among the storey-resistant elements designed by torsion and of the factors which affect the design eccentricity, specially accidental eccentricity, are studied. It is demonstrated that the effect of accidental eccentricity is always additive for the structural elements. There is … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Ethical Appraisal of Hormesis: Towards a Rational Discourse on the Acceptability of Risks and BenefitsOrtwin RennIt is ethically mandated that potential beneficial aspects of low exposure to potentially hazardous material are incorporated in the risk-benefit balancing procedure. The potential harm done by pollutants does not justify the invocation of a categorical principle. Minimisation of risk is not required if health benefits are also at stake. Society needs to find an informed consent on the threshold … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Pile- Soil Interaction Subjected to Lateral Loads in Layered SoilsA. Avaei, Abdoul R. Ghotbi, M. AryafarTo stabilize infrastructures such as tall buildings, bridges, etc., piles are used to resist lateral loads created from earth pressure, wind, waves and earthquake extensively. Pile design requires understanding of how the load is transferred from a pile to surrounding soil and vice versa. Pile properties, soil stress-strain behavior and pile-soil interaction play important roles in pile-response subjected to lateral … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Determinants of Urban Household Poverty in MalaysiaT. Y. Mok, C. Gan, A. SanyalSince independence in 1950s Malaysia has been recognized as one of the more successful countries in fighting poverty: head count ratio came down to 5.7% by 2004. However the recent process of rapid urbanization has led to an increase of urban poverty aggravated further by the 1997 Asian financial crisis. It is important to understand the nature and scale of … …Journal of Social Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 9,855 accessesView PDFCite
