Este estudo está vinculado ao Grupo de Estudos e Pesquisas em Política Educacional, GREPPE (grupo interinstitucional) – Seção Rio Claro, mais precisamente ao Projeto de Pesquisa intitulado “A oferta educacional na educação infantil: arranjos institucionais entre o público e o privado”, coordenado pela Profª Drª Raquel Fontes Borghi que trata sobre a oferta de vagas das escolas de Educação Infantil no estado de São Paulo. O presente estudo pretende analisar as relações entre o público e o privado, buscando perceber se o repasse de subsídios às instituições conveniadas (com ou sem fins lucrativos) pelas prefeituras municipais representa uma política pública educacional efetiva para a oferta de vagas na Educação Infantil. Para o estudo serão analisados os municípios denominados “muito pequenos”, com população máxima de até 10 mil habitantes. A pesquisa será qualitativa, bibliográfica e documental, realizada através de entrevista previamente estruturada em forma de questionário, anexo ao final deste relatório, por meio de telefonemas e e-mails e referendado por outros estudos já concluídos no GREPPE. Após a coleta de dados, os mesmos serão analisados através de bases teóricas relacionadas ao assunto e convertidos no relatório de pesquisa para o Trabalho de Conclusão de Curso

This work studies the incorporation of new technologies in the sugarcane sector. Are considered the ethanol steam reforming and the gasification of sugarcane bagasse(by-product) processes associated with combined cycle systems (Gas Turbine + Steam Turbine), aggregating hydrogen production and increased electricity supply in the sector, respectively. To verify the technical feasibility of the incorporation processes was performed a thermodynamic analysis, considering data from a typical Brazilian Sugar Cane Industry. In another step the economic viability study of the hydrogen production process was made, with consideration on hydrated and anhydrous ethanol steam reform, comparing the cost of hydrogen production. Also considered studies of economic engineering of the gasification process and the generation of electricity associated. As conclusions, it follows that the ethanol steam reforming is a great alternative for hydrogen production, presenting production cost relatively low, especially when is considered the steam reforming of hydrated ethanol. For the gasification process associated with combined cycle, can be observed an increase of 8.56 times of the electricity production in the sugar cane industry, indicating a positive annual saving when the sales price of the supply electricity is greater than 0.070 US$/kWh. Finally it can be concluded that the incorporation of these new processes allow greater profitability and operational flexibility of Brazilian sugarcane mills

The aim of this paper is to discuss the issues of supply, service and training put in the brazilian National Education Plan (Law No. 10.172/2001), whose term expired in January 2011. Since a new project of the National Education Plan for the next decade, is currently under discussion in Congress, believe to be of paramount importance to examine which goals that have been achieved, which were partially achieved and what have not yet been achieved, always aiming to better development of professional education in Brazil, we consider mode of teaching still undervalued in the context of public education policies in Brazil.

This work evaluates the existing potential in the state of Sao Paulo for the generation of electrical energy using the sugar cane bagasse as fuel. As the bagasse is a by-product of the sugarcane and alcohol industry and it is produced in large scale in the country, mainly in the state of Sao Paulo, it is important to develop researches that aim the best utilization of this input. In order to determine its potential, at first, a study was conducted considering the utilization of the cogeneration, which is a common practice in the plants of the sector. However, it was concluded that the cogeneration could provide a higher quantity of energy if more modern technologies and more efficient processes were used. Another study to estimate the potential considered a system of gasification of the sugar cane bagasse integrated with the combined cycle (BIG/GTCC). It was concluded that this technology can provide a considerable increase in the electrical supply. In this work it was also developed an energetic study based on real data from a plant located in the state of Sao Paulo. A thermodynamic analysis was done in the existing equipment of the cogeneration section of the plant. And another analysis was done considering the implementation of the BIG/GTCC technology to the cogeneration system. Comparing the results of both settings, it was concluded that the utilization of the sugar cane bagasse integrated to a combined cycle increased considerably the efficiency in the generation of electricity of the plant, increasing more than six times its production capacity of electrical energy
