15. Análise do comportamento dos retornos acionários frente ao registro de ofertas públicas de aquisição de ações no Brasil
The informal asymmetric level, which means the time needed for transcribed assets to incorporate new information available in the market, allows abnormal gain by companies in the market, as it is the assumption that the market efficiency presents itself in a semi-strong form. According to this scenario, the present study aims to examine the relationship betw

20. Estudo das características de relâmpagos nuvem-solo negativos através da análise comparativa de observações por múltiplas técnicas. / Study of negative cloud-to-ground lightning features from comparative analysis of observations by multiple techniques.
For the first time in Brazil, an electric field antenna for lightning radiation, with 1.25 µs resolution was developed. From thunderstorms over Sao José dos Campos, between February and March of 2003, information of lightning synchronized to GPS time, were simultaneously obtained by this antenna, by a 1ms resolution high-speed camera and by the Brazilian L

23. MODELOS ESTATÍSTICOS NA PESQUISA DA PROPAGANDA / STATISTICAL MODELS IN ADVERTISING MARKET RESEARCH
The advertising is no doubt one of the most important weapons of Marketing. However, to measure its short-term efficiency as the result of sales increase can be a difficult task, mainly when it is compared to promotion results. For that, statistical models are being developed using other measures rather than sales volumes. At the same time, the advertising t

24. Wall stress and patterns of hypertrophy in the human left ventricle.
It is generally recognized that chronic left ventricular (LV) pressure overload results primarily in wall thickening and concentric hypertrophy, while chronic LV volume overload is characterized by chamber enlargement and an eccentric pattern of hypertrophy. To assess the potential role of the hemodynamic factors which might account for these different patte
