the aim of this research is to simulate oil spill behavior in the persian gulf due to the wind andtidal currents. this is achieved by coding an oil spill mathematical model consisting of several major submodels including hydrodynamic model, oil slick dynamic model and oil weathering model. the base of all of them is eulerian approach and they are coupled together to simulate spill incident in t...

prediction of supersolubility and the width of the metastable zone has been a major concern among the workers in the field of industrial crystallization. operation of crystallizers under the optimum supersaturation low enough to attain the desired product quality (median particle size, crystal size distribution (csd), shape, purity) being one motif. the inherent relationship between the subject...

Orthopaedic implants have been the subject of intense research in recent years, with academics, clinicians and industrialists seeking to broaden our understanding of their function and potential consequences within the human body. Current research is focussed on ways to improve the integration of an orthopaedic device within the body, whether it be to encourage better osseointegration, combat p...

Whether and what type of the lobbying-induced trade policies can improve the domestic welfare? We show that as compared to the case of no lobbying and the case of domestic lobbying, the domestic-foreign lobbying achieves the lowest tariff and may also realize the highest welfare for the domestic country. Our results suggest that the domestic-foreign lobbying may contribute to a freer trade in t...

within the early theories of fdi and multinational firms, fdi and foreign trade were considered to be substitutes. new international trade theories emphasize, however the complementary relationship between fdi and foreign trade.this is the result of introducing new aspects in the models like increasing returns to scale, product differentiation and technology-differences among nations.this paper...

This study attempts to examine empirically dynamic causal relationships between carbon emissions, energy consumption, income, and foreign trade in the case of Turkey using the time series data for the period 1960-2005. This research tests the interrelationship between the variables using the bounds testing to cointegration procedure. The bounds test results indicate that there exist two forms o...

This paper investigates international technology diffusion through trade and patenting in a sample of 48 countries for the period 1980 – 2000. We divide the sample in three income groups to detect different patterns of technology absorption. Our results show that rich countries benefit from domestic technology and foreign technology embodied in imported capital goods, middle-income countries en...
