Research ArticleOpen accessIn the abstractGreen Methodologies to Test Hydrocarbon ReservoirsFrancesca Verga, Vera RoccaProblem statement: The definition and the economic viability of the best development strategy of a hydrocarbon reservoir mainly depend on the quantity and type of fluids and on the well productivity. Well testing, consisting in producing hydrocarbon to the surface while measuring the pressure variations induced in the reservoir, has been used for decades to determine the fluid nature and … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Web-Based Rapid Prototyping Workflow Management Information System for Computer Repair and MaintenanceA. H. El-Mousa, Z. J. Muhsin, M. A. Al-TaeeProblem statement: Response to paper-based requests for computer and peripheral repair and maintenance has become very troublesome and slow due to the large demand and expansion at the University of Jordan. The objectives of this study were to: (i) investigate the current system processes associated with the paper-based workflow system. (ii) design and implement, using a suitable workflow management approach, … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2009 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime Series Analysis Model for Rainfall Data in Jordan: Case Study for Using Time Series AnalysisP.E. Naill M. MomaniProblem statement: Time series analysis and forecasting has become a major tool in different applications in hydrology and environmental management fields. Among the most effective approaches for analyzing time series data is the model introduced by Box and Jenkins, ARIMA (Autoregressive Integrated Moving Average).

Research ArticleOpen accessIn the abstractBridging from Cells to Cognition in Autism Pathophysiology: Biological Pathways to Defective Brain Function and PlasticityMatthew P. Anderson, Brian S. Hooker, Martha R. HerbertWe review evidence to support a model where the disease process underlying autism may begin when an in utero or early postnatal environmental, infectious, seizure, or autoimmune insult triggers an immune response that increases reactive oxygen species (ROS) production in the brain that leads to DNA damage (nuclear and mitochondrial) and metabolic enzyme blockade and that these inflammatory and oxidative … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 17,461 accessesView PDFCite

Research ArticleOpen accessIn the abstractAn Economic Model of Insider Trading with an Informed Third PartyNasser G. ElkanjThe fact that an insider gains only at the expense of an outsider, manipulative insider trading precipitates a conflict of interests. We model this conflict in an extended principal-agent framework to demonstrate that the endogenous demand for reliable information would limit the volume and persistence of manipulative insider trading. An important dimension of such an insider trading is that an … …Journal of Social Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 6,810 accessesView PDFCite
