1. AnÃlise do Fluxo de Gases na Camada de Cobertura do Aterro SanitÃrio Municipal Oeste de Caucaia (ASMOC) / Analysis of gas Flow in covering layer of Municipal Landfill West of Caucaia (ASMOC)
The growing human consumption entails a greater generation of waste, which, in turn, must be properly treated and disposed. The storage of waste in landfills produces gas, which if not managed properly will affect the quality of life. The uncontrolled emissions of these gases cause multiple economic, social and environmental impacts, as due to air pollution

2. Medição do aporte atmosférico dos elementos-traço nos municípios de Campinas e Paulínia com auxílio da espécie vegetal Tillanásia usneoides (L.) / Measurement of atmospheric supply of trace elements in Campinas and Paulínia with support of vegetal specie Tillandsia usneoides (L.)
The epiphytic bromeliad Tillandsia usneoides (L.) was used as biomonitor of the atmosphere at seven sites along a transect of the municipalities of Campinas and Paulinia. The selected sites are located near highways, industries and avenues, as well as in places farther away from human activities. The samples of were introduced by about two months during five

3. Construção do conceito de medição por meio de uma estratégia pedagógica baseada no modelo didático de formulação de perguntas
The didactic laboratory is of addition importance in Physics learning since it contributes to relate theory and practice. However, studies tell that many students demonstrate difficulty in understanding the experimental activities for if they find in the Punctual Paradigm and, therefore, they carry problematic representations to the they come across the acco

4. Avaliação de parâmetros limnológicos, parasitas, bactérias e metais pesados em água superficial no córrego Ribeirão Preto, Ribeirão Preto - SP / Evaluation of limnological parameters, parasites, bacteria and heavy metals in superficial water of Ribeirão Preto Stream, Ribeirão Preto-SP.
Water is fundamental to life. Its multiple uses are needed for a broad spectrum of human activities, among which stand out, the public and industrial supply, agricultural irrigation, the production of electricity and leisure activities and recreation. It is known that Brazil still has a privileged position of water quantity and quality, but their use hasnt b

5. Contribution to the development of performance specifications for concretes containing blast furnace slag / Contribuição ao desenvolvimento de especificações por desempenho para concretos com escoria de alto-forno
In 2008 alone, the annual steel production in Brazil was around 31 million tons. The steel production process generates an average of 500 kg of residues and co-products per ton of steel. From this total, 70% corresponds to the slags. Although investigating the increase of blast furnace slag use is of extreme importance for the concrete and steel industries s

6. Proposal of implementation of environmental management system the laboratory of radioactive waste in IPEN-SP / Proposta de implantação de um sistema de gestão ambiental no laboratório de rejeitos radioativos do IPEN-SP
Constata-se, atualmente, um uso crescente da energia nuclear no Brasil, para geração de eletricidade e outras aplicações (na medicina, na indústria, em agricultura, em técnicas ambientais, em radio-esterilização). Na realização das atividades de pesquisa do ciclo do combustível nuclear, em outras atividades de pesquisa, nas atividades industriais

7. AvaliaÃÃo da retenÃÃo de gases em camadas de cobertura de aterros de resÃduos sÃlidos
Municipal solid waste landfills final covers work as a seal interface between the wastese and the external environment. This sealing layer is also responsible to avoid the infiltration of water into the waste mass and the emission of gases to the atmosphere. These interventions show by they own how important are both project and execution of the top cover as

8. ADEQUAÇÃO DO MODELO PMV NA AVALIAÇÃO DO CONFORTO TÉRMICO DE CRIANÇAS DO ENSINO FUNDAMENTAL DE IJUÍ-RS / EVALUATION OF THE THERMAL COMFORT OF STUDENTS IN ÍJUI - RS
The search for the knowledge of conditions that provide thermal comfort for children in classroom activities is justified by the background and support for the architectural strategies capable of provide the spaces pertaining to the school with better conditions of habitability and thus to contribute for an educative process of better quality. The demand of

9. Monitoramento atmosférico passivo de SO2, NO2 e O3 em áreas urbanas e de influência industrial como prática de química ambiental para alunos de graduação
This study is a result of undergraduate student participation in the Environmental Chemistry discipline provided by the Chemistry Institute/UFBA. The students were involved in the development of passive samplers, a project of the LAQUAM (Environmental Analytical Chemistry Laboratory). The students' residences and other neighborhoods were used to create a pas

10. Characterization and use of the Zerede Stream watershed, Timóteo-MG / Caracterização e uso da bacia hidrográfica do Córrego Zerede, Timóteo-MG
It is common the no integrated treatment of the studies of the natural phenomena, perhaps presupposing of that knowing some parts of a system it can be known in this whole. However, to conserve the nature, particularly the soil and the water, it is necessary the coordinated and integrated envolvement of everyone, making that the small watershed corresponds t

11. Biossensores amperométricos para determinação de compostos fenólicos em amostras de interesse ambiental
Phenols are widely used in many areas and commonly found as industrial by-products. A great number of agricultural and industrial activities realise phenolic compounds in the environmental. Waste phenols are produced mainly by the wood-pulp industry and during production of synthetic polymers, drugs, plastics, dyes, pesticides and others. Phenols are also re

12. Um novo método para estudos dinâmicos, in situ, da infiltração da água na região não-saturada do solo. / A new method for dynamic studies, in situ, of water infiltration in the unsaturated zone of soil.
Agriculture is the human activity that most affects the environment. Huge amounts of chemicals are applied on the soil. Pesticides percolation and runoff degrades water resources. Thus, soil hydraulic properties must be known due to their influence on solute transport. The measurement of these properties and the modelling of related parameters are often diff
