A pulverização eletrostática, quando utilizada de maneira correta, proporciona vantagens em relação aos sistemas convencionais. No entanto, diversos fatores podem interferir na eficiência do sistema. Por isso, objetivou-se, com este trabalho, avaliar a relação carga/massa (Q/M) em diferentes distâncias de pulverização (0, 1, 2, 3, 4 e 5 m) e a eficiência de(More)
A radiological assessment has been in progress, since 1978, on the environmental implications of an abandoned radium salts factory, operating in Portugal from 1912 to 1944. Some aspects of the study performed at the site are briefly described. They include the analysis of radium-226 concentrations in water and foodstuff and the identification of critical(More)

An efficient pesticides spraying depends a lot in psychrometric conditions, mainly if it is using fine droplets, once climatic conditions may cause droplets evaporation and consequent financial loss to the farmer. Thus, the aim of this work was to determine the droplet spectrum depending on the vapour pressure deficits. The work was carried out inside of a(More)
