1. Padrões de distribuição de mamíferos de médio e grande porte em paisagens fragmentadas / Distribuition patterns of medium and large size mammals in fragmented landscapes
Habitat fragmentation is defined as the breaking of a continuous habitat in patches or fragments. This process leads to environmental changes capable of affecting communities in different ways, causing species composition changes. Beta diversity measures can show the variation between the composition of different communities, where two ecological patterns ca

3. Regulação econômica e a expansão dos serviçosde distribuição de gás natural canalizado no Brasil
Esta dissertação trata da questão da regulação do setor de distribuição de gás natural canalizado no Brasil e as implicações que uma política de expansão dos serviços tem na regulação ótima. A primeira parte faz uma análise institucional do setor de distribuição de gás natural, identificando o papel da regulação no mesmo. A segunda part

4. ANALISE DA DINAMICA DE PARTICULAS BROWNIANAS INTERAGENTES A PARTIR DE REDES DE MAPAS ACOPLADOS
The Brownian motion is one important topic of the non-equilibrium statistical mechanics and it is related to many natural phenomena. The first observations and theories on this motion were essential for understand the microscopic behavior of the nature and its influence on macroscopics observables. In this dissertation, we studied the dynamics of a system co

5. Trees and treelets species in gaps and light micro-sites in 5,12ha of Restinga Forest in Ilha do Cardoso, Sao Paulo State / Espécies Arbustivo-arbóreas em clareiras e micro-sítios de luz em 5,12ha de Floresta de Restinga na Ilha do Cardoso, São Paulo
Tropical Forest dynamics studies elucidate the importance of knowledge about the relationship between light and distribuition of species to understanding the regeneration and diversity mainteinence of these communities. To contribute with this knowledge to Restinga Forest species this study described the distribuition of trees with dbh (diameter at breast hi

6. The expansion of the system of natural gas distribuition in Brazil: the dynamics of the investments, the income and the emissions of CO2 / A expansão do sistema de distribuição de gas natural no Brasil : a dinamica dos investimentos, da renda e das emissões de CO2
In Brazil the expectation of increase of the participation natural gas in the matrix energy exists. To analyze the necessary investments to the viabilization of this increase, the potential income generated with the commercialization of the natural gas and the C O IND. 2 emissions, allows the measurement of the decisions taking and the strategical planning p

7. Management effects on caxeta [Tabebuia cassinoides lam. (dc)] natural populations genetic diversity by molecular markers. / Efeito do manejo na diversidade genética de populações naturais de Tabebuia cassinoides LAM (DC), por marcadores isoenzimáticos.
Natural populations of Tabebuia cassinoides Lam (DC) have been intensively harvested in the last 70 years. The pressure for continuum exploitation of remaining populations remains, although few populations remain in conditions that allow commercial exploitation and recent studies indicated that intensive harvest causes strong loss of genetic diversity. Thus,

8. Estudos taxonomicos no genero Paspalum L., grupos "Virgata" e "Quadrifaria" no Brasil
The present work consists of taxonomic studies with the "Virgata" and "Quadrifaria" groups of Paspalum L. represented by their species in Brazil. The study was realized with living specimens mantained in experimental gardens and herbarium material and offers detailed descriptions, distribuition maps, leaf blade anatomy and numerical analysis though grouping

9. Caracterização dos fluidos H2S e agua em reservatorios carbonaticos
Reservoir fluids from two basins - Campos and Santos - of East Brazil margin have been studied. Samples from over 16 wells have been utilized in the fluid characterization. Water and hydrogen sulphide (H_) are fluids with large distribution in petroleum fields and may provide important informations for reservoir studies. High H2S concentratios are normally a
