As publicações da ANPAE e a trajetória do conhecimento em Administração da educação no Brasil

This paper reports on the trajectory of knowledge in educational administration, as published by the Brazilian National Association of Educational Policy and Administration (ANPAE). It reviews four early booklets on school administration – Cadernos de Administração Escolar – published between 1961 and 1968, and selected issues of ANPAE´s journal – Revista Brasileira de Política e Administração da Educação – published between 1983 and 2000, under different categories, and analyses those classified under the concepts of administration and management. The author refers to conceptual limitations, but concedes that the publications present relevant contributions on the theoretical development of educational administration in Brazil.

Tratamento de águas oleosas oriundas do processo de produção de óleo de dendê utilizando a flotação por ar dissolvido

This study was developed to evaluate the performance of different coagulant and pH dosages by applying the use of Dissolved Air Flotation (FAD) to enable its use in effluent treatment of the extraction process of palm oil. The study was developed in the laboratory, where studies about emulsions stability were made for the production of a synthetic effluent which best suit the characteristics of raw effluent. The synthetic water that would be used in the tests of FAD was produced, once the stability and characterization which best approached the raw wastewater was obtained. Trials tested three coagulant doses, combined with various pH ranges and five upward velocities (Va), finding an optimal range of this combination. Some operating parameters such as time and gradient of rapid mixing (20 s / 1000 s-1), time and gradient flotation (15 min / 60 s-1), chamber pressure saturation (450 kPa) and recirculation rate (20%) were set. In this way, samples were collected for analysis of the removal of turbidity parameters, suspended solids and oils and greases. This one is obtained by a correlation turbidity x oils and greases, referring to the previous analysis. The degree of removal obtained were 73,97% for turbidity, 51,4% for total suspended solids and 86,2% for oils and greases. Removal rates may be increased in later studies, by ranging the velocity gradient and flocculation parameters and the recirculation ratio, and by using lower flotation speeds to these effluent characteristics.

Considerações sobre a presença e características do tema água nas Propostas Curriculares para o ensino de Química/2009, do Estado de São Paulo

This study sought to raise the water issue is addressed in the teaching of chemistry in public schools through the notebooks Curricular Proposal of the State of Sao Paulo. First we tried to do a survey of knowledge related to construction of the concept of historical perspective, the physical and chemical properties, their importance to man and the particulars of the national curriculum for this subject. The methodology used was qualitative, descriptive and documentary. We analyzed the books for the first, second and third marking periods and the three series (the 4th book had not yet been distributed). As expected the first scenario, the proposed curriculum addresses the topic in greater depth in only one of the notebooks of the second year of high school. The approaches are no longer linked to health issues and the environment, cross-cutting issues considered by the NCP and important for students to make associations between the chemical content and their daily lives. We conclude that the contract should be evaluated by teachers and that their use should be involved in drawing up a plan that takes into account the aspects that seem incomplete. We also emphasize that although the proposal is interesting from the standpoint of teaching, teachers need training to its full use in the classroom
