This paper analyzes the impact of FDI on domestic firm entry and firm size distributions in 245 industries in the Czech Republic during 1994 to 2000. We find that larger foreign presence stimulates the entry of domestic firms within the same industry indicating the existence of positive horizontal spillovers from FDI. We also find evidence of significant vertical entry spillovers – FDI in downs...

One of the industries with high potential for energy saving is the petrochemical industry. Ethylene and propylene production plants (olefin plants) – as a part of the petrochemical industry – are very energy intensive. So, any try to improve their energy consumption efficiency could lead to a high amount of energy saving. Iran’s petrochemical industry uses old technologies and components and du...

The scope of this research is concerned with the supply chain of light aromatic compounds, i.e., benzene, toluene, o-xylene and p-xylene, in he petrochemical industries. The proper production scheme of these compounds over a specified time horizon can be configured by selecting hroughput, operating conditions and technology options for each unit in the chain, by maintaining the desired inventor...

OBJECTIVES The level of benzene exposure in the petrochemical industry during regular operation has been well established, but not in turnaround (TA), where high exposure may occur. In this study, the characteristics of occupational exposure to benzene during TA in the petrochemical companies were investigated in order to determine the best management strategies and improve the working environm...

OBJECTIVES To investigate concern that local industrial air pollution in Teesside, England, was causing poor health, several areas there were compared with parts of the City of Sunderland. METHODS Populations in similar social and economic circumstances but varying in their proximity to major industries were compared. Study populations lived in 27 housing estates in Teesside and Sunderland, n...

Reactive alkenes from petrochemical industries are known to play an important role in the formation of ozone in Houston, Texas. In this work we developed a fast-response detector of ethylene based on laser photo-acoustic spectroscopy (LPAS) and used it onboard the NOAA WP-3D aircraft to measure ethylene in industrial plumes around Houston in the summer of 2006. The new LPAS instrument was evalu...
