Research ArticleOpen accessIn the abstractEffects of the Mass Transfer Process in Oil SpillFabián Betancourt, Arturo Palacio, Alejandro RodriguezA revision of the models used to study the behavior of the mass loss processes associated with petroleum spills on water and to compare those models with experimental data. The processes of mass transfer studied in this work are evaporating, dissolution, vertical dispersion, emulsification and the changes of properties associated with these. The comparison of the estimations with the field … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,507 accessesView PDFCite
Research ArticleOpen accessIn the abstractOOST: An Object Oriented Tool for Satellite Orbit DesignA. A. Salem, M. Zaki, A. A. WahdanIn this study the problems of satellite orbit design and simulation are tackled and an object oriented satellite tool OOST is developed. The tool with its three main modules enables the user to plan and design different satellite missions. It performs all orbital calculations needed, simulates the target orbit and performs analysis on the current active satellite(s). The simulation module … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Solar Radiation SystemM.S. Alam, Sushanta Kumar Saha, M.A.K. Chowdhury et al.In this research work, a mathematical model for simulation of the solar radiation system has been developed by using a system dynamics methodology. Bangladesh is used here for model validation. The simulated results obtained from this model have compared with the experimental results and found reasonably a good agreement. Therefore the performance of the model is to be expected as … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,697 accessesView PDFCite

Research ArticleOpen accessIn the abstractThe Evolution of Today's Health Care EconomyEldo E. Frezza, Maurizio Chiriva-InternatiThe health care economy has fluctuated in the last 30 years. One of the contributing factors has been the reimbursement schemes used by hospitals and physicians, which has had a considerable impact on the behavior and performance of the health care market. Unlike health care markets in other countries, the U.S. has a multi-payer system. These third-party payers include the … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 6,657 accessesView PDFCite
Research ArticleOpen accessIn the abstractFirms and their Responsibility towards NatureJerome Ballet, Damien BazinCorporate social responsibility is increasingly discussed in economics and management studies today. Corporate leaders often make use of this concept, which finds its origins in philosophy, to analyse the normative behaviour of their companies. But what exactly is corporate responsibility? Is it a mere concept currently in vogue, or is it a new structural approach which could indeed take responsibility … …Journal of Social Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,155 accessesView PDFCite

Research ArticleOpen accessIn the abstractThe Finite-Sample Bias of the Autoregressive Parameter Under Rank-based EstimationSteven CookMonte Carlo simulation is employed to examine the finite-sample properties of the estimated autoregressive parameter associated with the Dickey-Fuller and rank-based Dickey-Fuller unit root tests. While the downward bias associated with estimator under the Dickey-Fuller test has long been noted in the literature, the corresponding properties for the rank-based test have not been considered previously. The results presented show that … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,242 accessesView PDFCite
