13. Uma contribuição para manejo dos resíduos da construção e demolição no município de São José dos Campos - SP / A contribution to managemente of the construction and demolition waste (CDW) on the municipal district of São José dos Campos-SP
The civil construction has great relevance for the Brazilian economy in the productive chain, but the deriving waste from this activity and reforms in residences, condominiums, schools, repairs and demolitions in buildings etc., provoke social environment impacts. First by wastefulness of no renewable raw material and by decreasing the capacity of use in the

14. Chemical waste generated in laboratories of UNICAMP management inventory and evaluattion / Residuo quimico gerado em laboratorios da UNICAMP : inventario e avaliação de seu gerenciamento
The chemical waste has emphasize among the generated waste types due, many times, to its high hazard degree. In this work an inventory of chemical waste active generated in laboratories of four UNICAMP Units was realized. It was inventoried and valuated the chemical waste generation from analysis realized in laboratories that more generate waste in Units sel

15. Modelo para avaliação da gestão municipal integrada de residuos solidos urbanos / Model for evaluation of integrated urban solid waste management
The present work aims at the development of an integrated solid urban waste management model highlighting the sustainability and the development of a methodology for evaluation of municipal waste management system. A field work was conducted in the cities selected for testing and validating the proposed methodology. The research range included the 20 cities

16. Técnica de gerenciamento da qualidade hídrica superficial baseada na otimização multiobjetivo / A technic of surface water quality management based on the multiobjective optimization
Problems of water quality management involve many aspirations of the users engaged, those that use water for wastewater dilution or for their consumption. Therefore, it is uncommon that decision-making mathematical models used are expressed in terms of a single objective, like the maximization of economic efficiency. Using a particular water system, one shou

17. Compostagem caseira como instrumento de educação ambiental e minimização de resíduos sólidos urbanos. Campos do Jordão, São Paulo / Residential Composting as an instrument of environmental education and reduction of solid wastes. Campos do Jordão, São Paolo.
No Brasil, a parcela orgânica dos resíduos sólidos urbanos (RSU) representa mais de 50% de sua composição, na grande maioria dos municípios. No entanto, a compostagem, como método de tratamento dos resíduos orgânicos, não é empregada como poderia, somente 1,5% dos RSU no país é compostados; mesmo a compostagem caseira sendo prática de baixo cus

18. Development of analytical strategies for the determination of the anti-hypertensive furosemide / Desenvolvimento de estratégias analíticas para determinação do anti-hipertensivo furosemida
The development and application of different procedures for the quantification of the drug furosemide, exploiting its reactions and physical properties are described. The presented methods were based in static and flow injection procedures. Among the static redox procedures titrimetry was applied, which exploited the hydrolysis and oxidation reactions of thi

19. Residuos da construção civil : analise de usinas de reciclagem / Residues generated by the constructive : ativities recycling plants
This work is an approach to the development for sustentability in the sector of the Civil Construction, focusing the residues generated by the constructive activities and its use in the recycled aggregates production. As the production process in the construction industry is based on a lineal model is unviable, it degrades the middle-atmosphere and they cont

20. Evaluation of minimization of ammonia emissions from the process of leachate treatment by evaporation. / Avaliação da minimização das emissões de amônia no processo de tratamento de chorume por evaporação.
O presente estudo tem por objetivo minimizar as emissões de nitrogênio amoniacal do processo de tratamento de chorume por evaporação. Amostras de chorume, provenientes de um aterro sanitário localizado na Baixada Fluminense, foram coletadas no período de maio de 2006 a abril de 2007, e caracterizadas por: pH, condutividade, nitrogênio amoniacal (N-NH3

22. Residuo solido domiciliar : potencial de minimização e potencial de conservação de energia com reciclagem em municipios da Região Metropolitana de Campinas
The work hypotheses are that a reasonable energetic potential associated to the solid waste might be discarded at the residences and that it is possible to minimize the quantitys of waste. The purpose of this study is to estimate the avoided energy associated to the potential minimization of the domestic solid waste produced in municipal districts of Campina

23. Potencial de minimização do material biodegradavel de alimentação contido no residuo solido domiciliar em municipios da Região Metropolitana de Campinas / Minimization potencial of food biodegradable material contained in the domiciliary solid waste in cities of the metropolitan region of Campinas
An increase of the amount and quality of the discarded material has arisen as a result of the urban growth and the change of consumption standards. With the production of material each day more complex and the composition of the waste being frequent1y modified, the treatment to this problem becomes more difficult. The worldwide trend, in relation to the prob
