Wake-passing in a turbine rotor cascade

Abstract

Once located in time and place the beginning of urbanization process, the mechanisms of adaptation to urban ecosystem and of dissemination by human conveyances are studied for two domestic mosquitoes: Aedes aegypti and Culex pipiens fatigans (= quinque-fasciatus). Then epidemiological consequences are discussed. Ae. aegypti pullulation constitutes a potential risk of urban yellow fever outbreak and the main factor of dengue haemorrhagic fever appearance; the increase of C. p. fatigans populations involves a slow rise of bancroftian filariasis. Future prospects for these diseases are discussed with regards to data concerning recent evolution of their own epidemiological features.
