1. Estudo palinoestratigráfico e de petrografia orgânica do Cretáceo inferior da Bacia do Recôncavo / Palynostratigraphic and organic petrography studies of the Recôncavo basin early Cretaceous deposits
The present study was based on vertical variations analysis of the organic matter from 50 core samples collected from the well 9-FBA-61-BA, allowing better understanding of the Early Cretaceous of Reconcavo Basin palynological and palynofacies characteristics. Observations throughout combined light and blue light/UV fluorescence techniques, permitted to defi

2. Características epigenéticas do depósito de cu-au chapada, arco magmático de goiás
The Cu-Au Chapada deposit is located from 8km of Alto Horizonte-GO. The geologic picture is dominated by metavulcanic sedimentary sequences that integrate the Neoproterozoic Magmatic Arc of Mara Rosa, located in the central portion of the Tocantins Province. The framework of the deposit is represented by an antiform whose core is composed by association of t

3. História paleoambiental neopleistocena-holocena, do médio Vale do Rio Paraíba do Sul, Estado de São Paulo: com base na análise da palinoflora.
This paper is about palynological studies realized at Paraíba do Sul river floodplain, in São Paulo. The hole made by vibro-core reached 390 cm depth. The core showed two very similar sedimentation cycles represented by sand in the basis, followed by clay and peat on the top. Besides, the second sequence presents one clay layer on the peat. The first seque

4. Geologia, geometalurgia, controles e gênese dos depósitos de fósforo, terras raras e titânio do complexo carbonatítico Catalão i , GO
This work describes the geological and geometallurgical characteristics of the phosphate, titanium, niobium and rare-earth elements deposits in the northeast part of the Catalão I carbonatite complex, Central Brazil. The mineralization controls were determined for magmatic, metasomatic and weathering processes. The ore types were defined on the basis of geo

5. Variações na acumulação de matéria orgânica, ao longo do holoceno, em sedimentos da região costeira de Ubatuba-São Paulo / Changes in the organic matter accumulation, during holocene, in coastal sediments from Ubatuba region-São Paulo
Changes in the organic carbon accumulation rates (Corg A.R.) and organic matter source characteristics and their relation to climate and relative sea level changes during the last 8.500 cal. yr. B.P. were investigated in two sediment cores from 2 embayments - Flamengo and Fortaleza inlets - northern coast of São Paulo State. Sediment samples were analysed f

6. O QuaternÃrio do Parque Nacional Serra da Capivara, PiauÃ, Brasil: morfoestratigrafia, sedimentologia, geocronologia e paleoambientes
The Serra da Capivara National Park is internationally recognized because it houses the most important concentration of rock paintings and archeological sites in the American continent. Vestiges of human occupation are distributed in 1.000 archeological sites many times located in Quaternary sediments, with few researches realized until the moment. The objec

7. "História ecológica da floresta de Araucária durante o Quaternário Tardio no setor sul da serra da Mantiqueira: análises sedimentológicas e palinológicas na região de Monte Verde (MG)" / "Ecological history of the Araucaria forest during the late Quaternary: sedimentological and palinological results from the Monte Verde region, Serra da Mantiqueira, Minas Gerais, Brazil"
Low annual average temperature (<18ºC), the localization in a zone of high altitude (>1500 m) and high floristic diversity, representative of the southern part of the Serra da Mantiqueira highlands, turn the Monte Verde region (city of Camanducaia, Southeast of the State of Minas Gerais), propitious for the inquiry of Late Quaternary climatic changes, the a

8. O ambiente deposicional da formação Carajas e uma proposta de modelo evolutivo para a Bacia Grão Para
The large Carajás iron ores belongs to the Carajás formation, which is a 100-400m thick banded and laminated iron formation (jaspilite), located at Pará state in North Brazil. This almost continuous formation outcrops for at least 260km, in 60 ore deposits, distributed in three main ridges, São Felix, Leste and Carajás. The last one is a sinformal struc

9. Contribution to the valuation of goodwill: core deposits, an intangible asset. / Contribuição à avaliação do goodwill: depósitos estáveis, um ativo intangível.
O presente trabalho tem como objetivo principal demonstrar que parcela da base de depositantes de instituições financeiras que se utilizam de depósitos (a prazo e a vista) como fonte de financiamento das suas atividades, identificada pelos depósitos estáveis, representa um ativo intangível da instituição depositária. Esse ativo intangível decorrent

10. Laminar-specific distribution and infrastructural detail of amyloid in the Alzheimer disease cortex visualized by computer-enhanced imaging of epitopes recognized by monoclonal antibodies.
Monoclonal antibodies to the A4 amyloid polypeptide were used in immunocytochemical staining of the Alzheimer disease prefrontal cortex. Analysis of the resulting staining patterns allowed us to evaluate the amounts and distribution of amyloid-protein deposits exclusive of other senile-plaque components. Previously unappreciated infra-structural details of a

11. Probing solvent accessibility of amyloid fibrils by solution NMR spectroscopy
Amyloid is the result of an anomalous protein and peptide aggregation, leading to the formation of insoluble fibril deposits. At present, 18 human diseases have been associated with amyloid deposits—e.g., Alzheimer's disease and Prion-transmissible Spongiform Encephalopathies. The molecular structure of amyloid is to a large extent unknown, because of lack

12. Type C RNA virus-specific antibody in human systemic lupus erythematosus demonstrated by enzymoimmunoassay.
Postmortem study of proliferative glomerulonephritis associated with human systemic lumpus has previously shown that an antigen related to mammalian type C RNA viral core (p30) proteins is deposited in the renal glomerular lesions with human immunoglobulins in an immune-complex pattern. In the present work, human immunoglobulins were sequentially eluted from
