The constant petrol fuel leak in gas stations has caused concern in many countries around the world. Those fuels have toxic organic compounds in their composition, like Polycyclic Aromatic Hydrocarbons (PAH), which are harmful to the human health. In this work the efficiency of the protection layer with a High Density Polyethylene (HDPE) membrane of 2.5 mm thickness was evaluated. The study was based in the diffusive process in the intact membrane by a permeameter developed to evaluate the diffusive process. The membrane was putted in the middle of the system to separate two sides: a local soil impregnated with diesel oil (in one side) and pure water (in the other side). The chromatography technique was conducted to evaluate the contamination in the pure water. The analyses were made monthly in a total period of 6 months of research. The results tests show that the membrane was less effective to antracene and naphthalene compounds. Despite that, the results showed that the HDPE membrane is a good alternative to prevent contamination of water and soil by the compounds under study up to one year, based on the performance in the time of study.

As transformações que tornam a sociedade mais complexa, configuradas na Sociedade da Informação, possibilitam novas formas de acesso as informações e conhecimentos que se manifestam em diferentes rela- ções sociais. No Brasil a valorização da leitura é um tema bastante recente, já que o Plano Nacional do Livro e da Leitura – PNLL - é de 2006. Tem como prioridade transformar a qualidade da capacidade leitora do Brasil e trazer a leitura para o dia-a-dia do brasileiro. Um dos eixos do plano é a Valorização da leitura e da comunicação, com ações para criar consciência sobre o valor social do livro e da leitura. O plano aborda a comunicação relacionada principalmente a dois aspectos: acesso à informação e comunicação sobre a leitura. A comunicação está sempre no centro da existência para qualquer sociedade, em desenvolvimento ou não. A partir de pesquisas sobre a leitura, o Instituto Pró-livro, uma entidade de caráter privado sem fins lucrativos, cujo objetivo principal é o fomento à leitura e à difusão do livro, utiliza-se de diversas estratégias de comunicação pública. Dentre essas experiências destacamos a Campanha “Mãe, lê pra mim?”, como uma prática de comunicação que busca levar informações aos cidadãos a partir do entendimento de se ouvir “as vozes locais”.

In modern society technologies have played an important space exerting influences in different spheres. Today's young people are born immersed in the digital and virtual reality, which has changed the ways of learning, as well as to relate to the world. All this context has intensified the debate on the potential of ICT in education and training means. In this study, we sought to investigate the teachers' vision of ICT in the school environment, how they are being incorporated into the school and the limits and possibilities of the use of ICT in the learning process. Questionnaires were administered to 150 teachers who teach in high school in the state network of São Paulo teaching, but specifically in Piracicaba. Continuing, semi-structured interviews with a group of 8 directors were carried out so that there was a deepening on the issues raised by teachers in the questionnaire. The research brought to light important issues for discussion and referral measures striving to support public policies of integration of ICT in schools. Teachers spoke about the advantages and disadvantages of their use and the process of integration. It was observed that, despite efforts to implementation, there are still problems with infrastructure of schools, teacher training and working conditions
