La Société d'Auteuil et la Révolution

The ' Société d'Auteuil ' and the Revolution. The author analyses the political role played by a group of intellectuals gathered together in a country house near Paris belonging to Madame Helvetius, wife of the well-known French philosopher, following his death in 1771 . These men (Volney, Garat, Chamfort, Mirabeau, Sieyès, Condorcet etc.) constituted the intellectual and political group most directly connected with the per¬ petuation of Enlightenment. Their activity, during the revolution, revealed both the revolutionary spirit and the uncertainties and weaknesses of the group, following the rapid sequence of events. The study of this activity by means of the diversity of individual attitudes permits a comparison to be made of the relationship between enlightenment and revolution to that between theory and practice.Moravia Sergio.

Evaluate of the anaerobic biodegradability of landfill leachate.

Os objetivos deste artigo foram investigar as condições ambientais e operacionais favoráveis ao desenvolvimento do teste de biodegradabilidade anaeróbia para lixiviados de aterro sanitário. As condições avaliadas foram a relação alimento/microrganismo (A/M), aclimatação do lodo, e toxicidade devido à alta concentração de amônia. Os resultados indicaram que a relação A/M equivalente a 0,45 apresentou-se como a mais favorável à realização do teste, e que o lodo empregado apresentou boa capacidade de adaptação ao lixiviado, não demandando aclimatação prévia. O lixiviado em questão apresentou relativamente baixa biodegradabilidade anaeróbia, associado aos resultados de estudos de biodegradabilidade aeróbia anteriores que sugerem que uma significativa fração de matéria orgânica é refratária mesmo ao metabolismo aeróbio,indica que o tratamento físico-químico deve ser utilizado como forma de pré ou pós-tratamento.The objectives of this article were to investigate the favorable environment and operational conditions to the development of the anaerobic biodegradability test for landfill leachate. The evaluated conditions were the relation food/microrganismo (A/M), seed acclimatization, and toxicity due to high ammonia concentration. The results indicated that A/M relation equivalent to 0,45 was presented as most favorable to the accomplishment of the test, and that the seed used presented good capacity of adaptation to the leachate, not demanding previous acclimatization. The leachate in question presented relatively low anaerobic biodegradability, and associated to the results of previous studies of aerobic biodegradability suggest that a significant fraction of organic substance is refractory to the aerobic and anaerobic metabolism, indicating that the physical-chemical treatment must be used as form of pre or post-treatment
