Dinâmicas centrípetas e centrífugas na formação do Estado monárquico no Brasil: o papel do Conselho Geral da Província de São Paulo

O presente artigo avalia a formação e o funcionamento do Conselho Geral da Província de São Paulo durante o Primeiro Império. Organismo previsto na Constituição de 1824, com funções que podem ser consideradas um embrião do Poder Legislativo provincial, organizou-se efetivamente na província de São Paulo em 1828, quando o governo de D. Pedro I já se desgastava. O significado de sua existência no contexto das dinâmicas centrífugas e centrípetas atuantes na primeira construção do Estado no Brasil independente constituem o principal objetivo da presente análise.

Estimativa das máximas pistas de vento no reservatório da barragem de Ilha Solteira, Estado de São Paulo

Most methods employed to estimate the height of waves generated by the wind require the surface length over which the wind blows. The choice of method depends on the nature of the water body, being applicable to ocean areas or interior water bodies, such as bays, lakes and reservoirs. One of the usual solutions has been the direct usage of the method validated in ocean waters for interior waters, therefore, not taking into consideration the effect of the restriction imposed by the shores. Nevertheless, the excessive quantity of operations of the method applied to interior water bodies (where the shore is a restraint condition) may not assure a satisfactory precision degree, unless an accurate enough graphic base of the shore with the addition of the operator's subjectivity is used. Thus, this scientific community brings this discussion to light, proposing a classic solution based on the application of the adequate method to interior waters (Saville et al., 1954) via automatized processing. Therefore, a program in AutoLISP, a computational language, has been developed. The application of the program has determined the maximum wind fetches in Ilha Solteira, state of São Paulo, reservoir as being between 9.5 and 12.5 km, in contrast with a previous study which has predicted far longer fetches (factor of three).
