1. Sodium Chloride Crystallization by Electric Discharge in Brine
Electrical discharges in liquids are currently used to synthesize nanoparticles. The plasma-liquid interaction is complex, where parameters such as electric field, ion charges and other species present are important. In order to understand the mechanism of crystallization, mother liquor (saturated solution of NaCl, MgCl2 and KCl) was used to study the effect

2. Caracterização físico-química de materiais baseados em celulose
Switching cutout devices are electrical circuit breakers which protect electric power distribution webs against lightning discharges. Switching cutout devices main parts are the fuse links in which a fuse element, a special metallic alloy, melts due to the generated heat when struck by electric discharges. When such melting occurs, and the breaker opens, an

3. ESTUDO PARA O DESENVOLVIMENTO DE UM PREVISOR DE DESCARGAS ELÉTRICAS ATMOSFÉRICAS APLICADO À REGIÃO COSTEIRA DO ESTADO DO RIO DE JANEIRO
The atmospheric dynamics evidently is very complex. There are many macro and micron scales processes and meteorological variables involved in the atmospheric physicalphenomena. The storms with electrical discharges are distinguished, among these phenomena, by the damage consequences to the human beings, directly or indirectly. Many researchers have pursued t

4. Implementação de uma rede neural artificial para associação de imagens de radar meteorológico e dados de descargas elétricas / A combination of weather radar images and electrical discharges using an artificial neural network
This work uses radar images together with data of electrical discharges derived from a lightning localization system taken with a Doppler Meteorological Radar as the input to a Neural Network (NN), in order to stablish the non-linear relationship between the reflectivity in the radar images and the atmospheric discharges. Associating these atmospheric discha

6. Contribuição ao estudo dos efeitos da tensão disruptiva de impulso atmosferico em materiais isolantes
Insulating materials subjected to electrical discharges deteriorate gradually and can lose their electrical characteristics along the time. This work investigates the effect of some insulating materials - low density polyethylene, poly (methyl metacrylate) and porcelain - in breakdown voltage atmospheric and, also, the effect of the electric discharges (indu
