4. Valoração ambiental do Parque Estadual da Serra do Mar - Núcleo de Satana Virgínia / Environmental valuation of Serra do Mar State Park - Núcleo Santa Virgínia
The main objective of this work was to develop an environmental valuation study of Serra do Mar State Park - Núcleo Santa Virgínia. The journey cost approach (MCV), was utilized to validate arguments for the preservation and recuperation of the Atlantic Forest and to estimulate sustainable forms of tourism in the Park area. Beyond that, the present work fo

6. Levantamento de formicídeos de fragmento de floresta atlântica no município de Eng. Paulo de Frontin, RJ (Hymenoptera, Formicidae). / Formicidae survey in a fragment of Floresta Atlântica in the county of Eng. Paulo de Frontin, RJ (Hymenoptera, Formicidae).
The east coast of Brazil, is lined with a chain of mountains where a forest known as Mata Atlântica develops. The vegetation of these mountains, because of its proximity with the coast, is under the influence of the trade winds full of humidity, from the ocean. Originally the forest extended for almost all the coast, from Rio Grande do Norte to the Rio Gran

7. Development of immunoassay techniques to detect microcystin in environmental samples / Desenvolvimento de técnicas de imunoensaio para detecção de microcistina em amostras ambientais
The contamination of drinking water by cyanobacterial toxins is a public health issue and a concern for water authorities throughout the world. Microcystin-LR (MCLR) is a hazardous cyclic heptapeptide cyanotoxin, which inhibits protein phosphatase PP1 and PP2A in hepatocytes. Microcystins are produced by several genera of cyanobacteria and presents more than

8. Fertilidade das camadas superficiais do solo em diferentes estágios sucessionais, no domínio da Mata Atlântica, no nordeste do estado de São Paulo / Soil fertility in superficial layers from differentes sucessions periods in Atlantic Rain forest from northeast of São Paulo state, Brazil.
In present study we evaluate the fertility variation in superficial layer of the soil in areas with primary Atlantic Forest cover, initial and late successions stages placed in Serra do Mar and Serra da Mantiqueira and pasture areas with aims to quantify the levels of degradation and recuperation through environmental chemical impacts in soil indicators. The

9. Effect of the application of organic compost on the process of crust formation and the recuperation of degraded soils by water erosion / Efeito da aplicação de composto orgânico sobre o processo de encrostamento e a recuperação de solos degradados pela erosão hídrica
The generation of organic waste along with soil erosion are two major environmental problems worldwide. They are responsible for the reduction of agricultural productivity and high environmental impacts. The objective of this dissertation is the use of organic waste generated in agriculture, in the form of organic compost, for the recovery of degraded areas

11. Metaproteomic and biochemistry hydrocarbons and heavy metals-contaminated soils / Metaproteomica e bioquimica de solos contaminados por hidrocarbonetos e metais pesados
Hydrocarbons, heavy metals and agricultural defensives are high risk pollutants to human health. These pollutants are constantly introduced into the environment as a result of petrochemical, industrial, agricultural activities and our modern life style, requiring remediation processes that are used to their complete elimination. Bioremediation is a process c

12. The final destination of domiciliar solid residues in our country and the of modern DSR incineration methods / A problemática econômica e geográfica em que se inserem a gestão dos resíduos sólidos domiciliares e os modernos métodos para sua incineração
A destinação final dos resíduos sólidos domiciliares (RSD) constitui, em nosso país, um problema de graves proporções. Os impactos ambientais e sociais que representam as práticas de aterramento desses resíduos conjugam-se, nas grandes cidades, com a carência de áreas apropriadas a estas finalidades devido aos elevados (e crescentes) índices de c
