The objective of this study was to evaluate the effect of immersion for varying periods in different concentrations of gibberellic acid and separate methods of scarification on the germination of seeds tucum. In the first trial, testing different soaking periods (24 and 48 hours), different forms of soaking (fast and slow) and different concentrations of gibberellic acid (0, 100 and 200 mg L-(1)) compared to the control (water) under completely randomized design in a factorial 2x2x3. The second experiment evaluated the different scarification treatments being: physical (seed coat removal in the hilar region with the aid of a scalpel), chemical (sulfuric acid 98 PA for 2:04 minutes) and thermal (hot water at approximately 98 degrees C and cold water at about 2 degrees C for 4 minutes). In the first trial were evaluated % of contaminated seeds (seeds infected by microorganisms) and hard seeds (who did not start the germination process, but not soiled), and in the second we assessed germination percentage (%) every two days for three months; germination Speed Index (GSI), time to occurrence of 50 % germination (T50) and Emergency Speed Index (ESI). The use of gibberellic acid was ineffective in promoting germination of Tucum (Astrocaryum Huaimi Mart.). Scarification treatments were effective in promoting germination and emergence of seedlings in the nursery and the most efficient physical removal scarification of the seed coat in the hilar region with the highest percentage of germination.

The main goal in this research is a tectono-estructural characterization of the Cherne, Albacora and Namorado Fields, located at Campos Basin, in order to investigate the relationship between the geologic evolution and the rock´s physical properties of the reservoir, and how they affect the hydrocarbon accumulation in those fields. Well correlations show that the inferior turbidites have a regional lateral continuity. Basic petrophysics analysis, calculated here, shows that the three fields present porosity values that range from 15 to 20%, shale volume range from 26 to 30% and formation water saturation range from 23 to 45%, based on formation water resistivity dada from Albacora Field. Petrophysics maps feature a trend in Albacora Field that increase the porosity values to SE, and in Cherne and Namorado Field the trend increase towards N. Seismic horizons where interpreted between the first appearance of the Namorado Sandstone and the top of Quissamã Formation. This interval presents normal listric faulting, in Cherne and Namorado Field with NWSE and NE-SW direction, and sedimentation trend to NW-SE, in Albacora Field the faulting presents a NNE-SSW and N-S direction, with a sedimentation trend to NE-SW. Seismic attribute maps present amplitude anomalies close to the producing wells, and on Namorado Field, it indicates a potential hydrocarbon accumulation in the NE region. For each field is indicated laboratory tests for a better characterization of the petrophysical properties, since that they don’t form the same reservoir level, therefore, not influencing the water saturation calculation
Caracterização estrutural do Lineamento de Piúma e sua influência na porção norte da Bacia de Campos

The detailed study of the Brazilian continental margin basins became possible with the advancement of geophysical tools, with emphasis on seismic reflection. Characterizing the structural and stratigraphic elements of Brazil’s marginal basins they realized that there was a relationship with structures present on the adjacent continental basement. So many works began to be made to understand this relationship and know the major factors that influenced the evolution of the continental margin. The study area of this work includes the northern portion of the Campos Basin and the continental outcropping adjacent areas, which corresponds to the northern of Rio de Janeiro state and the southern of Espirito Santo state. This area stands an important structural feature of NW-SE direction with a projection to the Campos Basin called Lineamento de Piúma. The outcropping basement rocks belongs to the Ribeira Belt which was bonded to other mobile bands forming the continent Western Gondwana during the Brasiliano Cycle, which later fragmented giving rise to the Atlantic Ocean. The opening of the ocean results on the formation of the marginal basins of Brazil. These basins have continental, transitional and marine facies. On Campos Basin the continental phase resulted on the formation of horsts and grabens bounded by synthetic and antithetic faults. Continuing rifting formed the saline lakes that deposited siliciclastic and carbonate sediments. The transitional phase resulted on thick packages consist of evaporites (halite and anhydrite) that was deposited in lagoon environment, tectonically quiet arid and semi-arid. The marine phase it deposited siliciclastic and carbonate in the Campos Basin resulting in shales, marls, limestones, ritmito, turbidites, sandstones and others. The objective of this study is to investigate the possible continuation... (Complete abstract click electronic access below)

A monografia aqui apresentada tem como foco o estudo do processo de estruturação do espaço urbano, com atenção para o papel dos shopping centers. Estes espaços de comercialização de bens e serviços são muito importantes para compreender tal processo e se trata de algo extremamente recente considerando-se o longo processo de urbanização, visto que sua expansão, como fenômeno urbano no Brasil é do inicio da década de 1980. O estudo privilegiou a caracterização e análise das cidades que apresentam população na faixa de 100 a 600 mil habitantes e que na sua estrutura urbana apresentem este empreendimento como um elemento que agregue ou não o poder de constituição e/ou (re)definição de centralidades, dinâmica esta bastante influenciada pela construção deste equipamento de lazer e consumo em uma cidade. Sendo assim, para o desenvolvimento deste estudo, procuramos nos nortear em questões que abarcassem qual a relação destes empreendimentos, quando existentes nas cidades, com a centralidade principal, para assim, tentarmos compreender se os mesmos desempenham a criação de novas centralidades, ou reforçam a centralidade principal já existente, concebida pela estruturação que o centro desempenha

A presente monografia tem a finalidade de refletir como a imagem poética é construída na poesia concreta de Augusto de Campos. Para isso, será utilizada a teoria de alguns estudiosos, como Alfredo Bosi, Octavio Paz, Philadelpho Menezes, Aguillar, entre outros, para embasar a reflexão sobre a imagem poética que se desenha a partir da leitura da poesia por meio das palavras que compõem a produção artística. Há uma ênfase, durante a análise das poesias, nas palavras que as constituem, pois elas formam um elemento fundamental para a criação da imagem poética na produção da poesia concretista. O trabalho também reflete sobre a repercussão do movimento Concretista em décadas distintas (50,70 e 90) e em diferentes vertentes, como na música, nos âmbitos nacional e internacional, ressaltando a importância do Concretista para o enriquecimento da poesia, especialmente as compostas por Augusto de Campos. Também será mencionada a diferença entre a poesia visual e a poesia concreta. Para isso, serão explicitadas as suas peculiaridades e as suas propostas
