Características físico-químicas, cozimento e produtividade de mandioca cultivar IAC 576-70 em diferentes épocas de colheita.

The instability of cassava culinary quality is a problem in the market. This work had the purpose of evaluating the interference of the productivity, rain precipitation and physical-chemical characteristics on the cooking time of the IAC 576-70 cultivar, from the 6(th) to the 12(th) month after the planting. The physical parameters evaluated were: difficulty in peeling (easy, medium, and hard), difficulty in cutting in long, thin sticks with a manual machine, being those cut in a subjective way. In the analysis of the cooked root, the percentage of water absorbed into the cassava pieces, the color, white points formed inside the pieces of cassava, gel formation around the pieces of cassava, and cooking time were evaluated. The pH, acidity, moisture, ashes, fibers, ether extract, protein, reducing sugars, and starch of the roots were also monthly evaluated. From the results obtained in the present work, it may be concluded that the cassava IAC 576-70, when planted in July, in Botucatu-SP area, must be harvested at the age of nine months, without damage to the productivity, starch level and root cooking, and the harvest could be extended up to ten months. The producers should follow the sum of precipitation index ten days before the harvest, and this value should be the smallest as it may be and the producers should not harvest when this value is more than 100 mm, in order not to hinder the cooking of the root.

Concepcoes estratigraficas em analise de bacias: C) a estratigrafia genetica

The present work fits the concepts of depositional systems and depositional sequence as paralithostratigraphic and parachronostratigraphic units, respectively, and discusses the advantages of using this approach in environmental reconstructions. The depositional system concept came to a focus as a link between sedimentology and stratigraphy since it represents both a facies association and a mapping unit. Additionally, the depositional sequence represents the sedimentary episode of relative sea level change, in interaction with basin paleophysiography. In such a way a time-space diagnosis is reached in environmental interpretation as illustrated by the Permian-Carboniferous sequence of the Parana Basin. -English summary

Sacralità del testo costituzionale ed eresia interpretativa: la sentenza della corte suprema brasiliana sulle unioni civili omosessuali

The paper provides a close lecture of the arguments and methods of legal construction, employed in the extensive individual opinions written by the Justices of the Brazilian Supreme Court in the case which authorized the same sex civil union. After tracing an outline of the legal problem and his possible solutions, we analyze the individual opinions, showing their methodological syncretism, the use of legal methods and arguments in a contradictory way as well the defciencies in the reasoning. The Justices use legal arguments, but do not meet the requirements of rationality in the decision-making. We have a rhetorical attempt that aims to satisfy the public opinion rather than to ofer a comprehensive and coherent solution according the normative elements of the Brazilian Federal Constitution of 1988.
