Abstract
Several corrosion inhibitors, such as, HEDP, sodium molybdate and zinc ions, were added to an aqueous corrosive media containing different concentrations chloride ions, and the corrosion rates (CRs) of carbon steel were measured at various temperatures. It was shown that, in the presence of more than 1,200 ppm of chloride ions, and temperatures greater than or equal to 42.5°C, the combination of HEDP, molybdate and zinc could not control the corrosion in a cooling water system. Then four different models were designed to represent the CR of carbon steel in presence of various corrosive parameters.

Abstract
Attempts to discover an internal logic in the high‐speed events taking place in the former Soviet Union. In addressing the problems of the country′s disintegration, examines the issue in its socioeconomic, political and territorial‐administrative aspects. Analyses, for this purpose, the nature of Soviet society prior to Gorbachev′s reforms, its present transitional stage and its probable direction in the near future.
