1. Sedimentologia e cronologia por luminescência da Ilha de São Francisco do Sul (SC): considerações sobre a evolução holocênica de barreiras arenosas da costa sul e sudeste do Brasil / não infomado
São Francisco do Sul Island (SFSI) is located on the northern coast of Santa Catarina State, Brazil. It covers an area of about 265 km2 with an approximate length of oceanic coastline of 40 km. The island was formed by coastal depositional systems active during the relative sea-level changes of the last 120,000 years. The following relative sea -level fall

2. Aplicação da estratigrafia de sequências para caracterização em multiescala de reservatórios no Grupo Guatá (Eopermiano da Bacia do Paraná) na Região São Gabriel-RS, Brasil
Detailed stratigraphic analysis of the Early Permian Rio Bonito and Palermo Formations of the intracratonic Paraná Basin in the region of São Gabriel County has been used for a study on reservoir characterization of paralic sandstones. Two main depositional systems were recognized, a fluvial-dominated delta system at the base and a wavedominated barrier is

3. Significant genetic differentiation among populations of Anomalocardia brasiliana (Gmelin, 1791): a bivalve with planktonic larval dispersion
Four Brazilian populations of Anomalocardia brasiliana were tested for mutual genetic homogeneity, using data from 123 sequences of the mtDNA cytochrome oxidase c subunit I gene. A total of 36 haplotypes were identified, those shared being H3 (Canela Island, Prainha and Acupe) and both H5 and H9 (Prainha and Acupe). Haplotype diversity values were high, exce

4. A erosão costeira e sua influência sobre a atividade petrolífera: alternativas sustentáveis na mitigação de impactos ambientais
The study area consist in high sensitivity environments located on the northern coast of Rio Grande do Norte, Northeast Brazil. The barrier island are the main geomorphological features on the coastal landscape, being naturally instable and surrounded by industrial activities like oil fields, salt industry, shrimp farms and urban areas sometimes installed pa

5. Relações entre a morfodinâmica e a utilização em trechos da costa oceânica da Ilha de Santa Catarina, SC, Brasil
This Doctorate dissertation analyzes the relation among morphodynamic characteristics of oceanic sandy beaches and the use of its coast. The study area is the oceanic coast of Santa Catarina Island, in Florianópolis, SC, southern Brazil. First of all, data about forty beach profiles, which had been monitored, were collected. Several parameters were analyzed

6. FILOGEOGRAFIA DO GÊNERO NEOTROPICAL Fluviphylax (CYPRINODONTIFORMES: POECILIIDAE) DAS BACIAS DO AMAZONAS E DO ORINOCO
A systematic and taxonomic study of the genus Fluviphylax was conducted using molecular methods, the COI gene and the control region of the mitochondrial DNA, and morphological methods. Additionally, a phylogeographic and population genetic study of Fluviphylax species was performed using the COI and control region sequence data in order to understand ecolog

7. Shape transition and dislocation nucleation in strained epitaxial islands
We study numerically the equilibrium shape, shape transition and dislocation nucleation in strained epitaxial islands with a two-dimensional atomistic model, using interatomic potentials of Lennard-Jones type. The phase diagram for the equilibrium island shapes as a function of island size and lattice misfit with the substrate is obtained by an energy minimi

8. "Morfologia e sedimentologia ao longo do sistema praia-duna frontal de Ilha Comprida, SP" / "Morphology and sedimentology along the beach-foredune system of Ilha Comprida, SP".
Ilha Comprida is a Holocene sandy barrier-island located on the south coast of São Paulo State, 63 km long and 2 to 5 km wide. Its transverse boundaries are Cananéia and Icapara inlets, at the SW and NE, respectively. The beach-foredune system of Ilha Comprida have experienced intense morphological variation in time, as showed by the successive truncations

9. Dinâmica Costeira dos Campos petrolíferos Macau/Serra, litoral setentrional do Estado do Rio Grande do Norte
This thesis describes the general behavior of the northern shore of the State of Rio Grande do Norte relating beach profile morphology with hydrodynamic and sedimentological parameters. The Macau and Serra Oil Field are inserted on this area and are under accelerated coastal erosion. At these oil fields are installed oil wells from PETROBRAS, nowadays locate

10. Interpretação de dados de GPR com base na hierarquização de superfícies limitantes e na adaptação de critérios sismoestratigráficos
Due to its high resolution, Ground Penetrating Radar (GPR) has been used to image subsurface sedimentary deposits. Because GPR and Seismic methods share some principles of image construction, the classic seismostratigraphic interpretation method has been also applied as an attempt to interpret GPR data. Nonetheless some advances in few particular contexts, t

11. Non-twist field line mappings for tokamaks with reversed magnetic shear
The structure of magnetic field lines in a tokamak with reversed magnetic shear is investigated by means of analytically derived area-preserving non-twist Poincaré maps. The basic configuration is the magnetic field produced by an ergodic limiter, superimposed to the tokamak equilibrium field in suitable coordinates. We consider the cases of one and two res

12. Genetic characterization of broad-snouted caiman (Caiman latirostris) populations by microsatellites markers. / Caracterização genética de populações de jacaré-de-papo-amarelo (Caiman latirostris), utilizando marcadores microssatélites.
A component considered critical for the managment well succeed of wild populations it is the maintenance of genetic variation. In the intention of evaluating the extend and the distribution of the existent genetic variability in populations of Caiman latirostris, nine populations distributed along the latitudinal axis of the distribution of the species in Br
