Brazil is nowadays the greatest bet of investors for the future due to its stable economy growth. The country has grown side by side with the greatest demand for electrical energy. The international appeal for renewable sources is causing a change in the Brazilian energetic matrix, raising the amount of energy generated by thermoelectric power plants. The construction of new power plants, running on biomass, requires a crescent number of capacitated personnel to run them. The Faculdade de Engenharia de Guaratinguetá – UNESP – has a steam laboratory; witch is deactivated, which has a thermoelectric plant of small capacity. The laboratory reactivation and the return of its activities can be an important tool in order to graduate engineer able to operate on such units. This paper proposes four new experiments to be simulated on the Collage’s Energy Dep. Steam Lab when it gets back to its educational activities

O Ribeirão Tanquinho, localizado no município de Botucatu, é totalmente inserido no perímetro urbano, da nascente a foz percorre 2.500 metros em área residencial, atravessando 12 quarteirões. A partir de 1998 ficou livre do esgoto e no ano de 2001 os quatro primeiros quarteirões da bacia foram alvo de um projeto de Recuperação Hídrico Florestal promovido pela ONG S.O.S. Cuesta de Botucatu, com o plantio de cerca de 5.400 mudas de árvores nativas visando à recuperação da área intensamente degradada. O presente trabalho teve como objetivo caracterizar a fauna (anfíbios, aves, répteis, peixes e mamíferos) do ribeirão Tanquinho, e gerar resultados que sirva de subsídios para ações ambientais no local, práticas de educação ambiental e também colaborar para o aumento do conhecimento acerca da fauna de Botucatu. Os trabalhos de caracterização de fauna foram realizados durante o período de fevereiro a outubro de 2008. Foram realizadas coletas no local e entrevistas com moradores ribeirinhos, a identificação dos animais foi realizada em campo, com exceção de alguns espécimes de peixes que foram retirados do local e identificados em laboratório. Para as coletas de um modo geral foi utilizada a observação direta com registro fotográfico dos animais, observação indireta através de vocalizações e procura por vestígios. Das 156 pessoas entrevistadas, 132 afirmaram ter visto algum vertebrado no local, no total foram registradas 03 espécies para o grupo peixes, 05 espécies de anfíbios, 06 espécies de répteis, 46 de aves e 07 de mamíferos (02 terrestres e 05 voadores)

PETROBRAS started in 2003 the implantation of agroforestry systems as an alternative to recuperate degraded areas at Oiteirinhos Farm, of its property, located in the biggest terrestrial field of oil of Brazil, between the cities of Carmópolis and Japaratuba, at Sergipe. The project, idealized by the geologist Ismael Quirino Trindade Neto and called Agrofloresta, sustento da vida, has the model of agroforestry systems developed by Ernst Götsch as technical and theoretical references, which joins agricultural cultures with forest species. In this direction, it was evidenced that the practices adopted in the SAFs allow to join recovery, conservation and production, as it follows the biodiversity and the dynamics of the natural processes as basic principles of the practices adopted. Including social inclusion and economic return, the project expands the environmental aspect, turning into an action focused in sustainable development.

The treatment of domestic and industrial effluents through Wastewater Treatment Plants (WTPs) generates a residue termed sewage sludge, rich in organic matter, high-volume, occasionally containing pathogens and heavy metals. The sludge generation can minimize the benefits brought by the treatment of sewage, because this residue does not always receive appropriate treatment before final disposal. The disposal is another problem related to sludge. Landfills generally does not have physical space and alternatives such as the use in agriculture requires an intense treatment that could be in many cases operational or economic unfeasible. The objective of this work is the theoretical research about the processes of stabilization of the sludge by anaerobic digestion and the methanogenic activity during the process. Through analysis of each step and contemplating each relevant factor in anaerobic digestion process in order to optimize them, we proposed a theoretical model of reactors capable of stabilize the sludge, reduce its volume and eliminate pathogens. The obtained configuration consists of two anaerobic reactors connected in series. The first one operates in the range mesophilic temperature (35 ° C) and has higher hydraulic retention time (25 days) working primarily in the stabilization of organic matter present in the sludge and producing biogas, whereas the second one operates in the thermophilic range (55 ° C) in order to eliminate pathogens, and to reduce the volume. The hydraulic retention time in the second reactor is lower (10 days). Both mesophilic and thermophilic processes were efficient in what was proposed, promoting the stabilization of organic matter present in the sludge and significant reduction of pathogens. As a final step with the sludge previously digested, it is indicated a final dehydration... (Complete abstract click electronic access below)

This work has the purpose of demonstrating how to build a Disaster Recovery Plan. In order to achieve such objective, an adaptation of the PDCA method was applied. This plan aims resuming the IT operations as fast as possible after some kind of incident which result the stop of the services or activities. Besides serving as insurance for the continued functioning of the company’s activities, indeed your non-existence brings up risks of financial loss and threatens the company’s image. As to illustrate the functionality and validity, the method was applied in an IT department of an energy company. It was concluded that the plan was well elaborated living up to the purposes described in the objective section of this work and validating the project developed so far, having a percentage of 85% of the overall success of the systems tested
