Strains of D. melanogaster derived from a vineyard population were more resistant to alcohol in the environment than strains from a population derived from an area removed from the vineyard. Within the vineyard population those strains most closely associated with alcohol in the environment in the cellar were more resistant than those collected outside the cellar. There was evidence of gene flo...

A multi-cell computer model of a family house with cellar was developed with the ventilation and contaminant movement computer prediction program BREEZE. The model was used to simulate the movement of radon gas from the cellar to the living areas of the house. Field measurements were also carried out under various controlled ventilation strategies. The paper outlines the development of the comp...

This paper investigates the induced stresses in circular single deck roofs floating on seismically excited storage tanks. Equations of motion are derived using variational principle. Response of deck floating roofs is evaluated for two different classes of ground motions; near-source and long-period far-field records. Besides time histories and frequency contents for a specific tank, peak value...

ports are the most important economic, political and military bottlenecks. this puts shoreline structures (port) in the class of important structures and they have a crucial role in the countries’ life. pile and deck wharf and their access bridges and offshore deck (jetties), are one of the parts which are supplier of coupling between the land and the waterfront. correct and exact estimation of...
