The Lagoa Feia Group (Early Cretaceous) is widely distributed around the Campos Basin, forming deep prospects in the basin. It has two large coquinas platforms shellfish, and the lower deck constituent important reservoir in the southwestern of this basin, a producer of oil in the trend-Badejo-Linguado-Pampo. Due to the rising national energy demand is necessary to see the incorporation of technical knowledge and training of human resources in the knowledge of petroleum reservoirs. In this sense, the Pampo Field, as well as other fields of the trend, fall as interesting target area for study. Accumulations of hydrocarbons are partitioning structural - stratigraphic only for the three fields. They are mixed origin of traps, with influence of structural, stratigraphic and diagenetic. With the development of catchment areas of the latter condition has manifested itself in such a way to verify parts with nonproducing wells, which are observed in the intervals coquinas are closed, with reduced thickness and / or low quality porous. The understanding of these accumulations, by testing structural, stratigraphic and reservoir and the use of geological and geophysical techniques, will bring a better understanding of the portions relating to economic accumulation or subeconomic development of hydrocarbons in this region, contributing to the scientific knowledge of the Pampo Field.

Introduces technical, economic and environmentally competitive solutions in the energy market is a great challenge for society. This work examines each of these aspects considering the production of electrolytic hydrogen with energy from wind power, solar and hydropower, in order to ensure an overview of this energy carrier. Initially, an assessment of the technical aspects is made addressing existing electrolysers technologies, its main characteristics and differences. The geographical distribution of wind, solar and hydroelectric potential in Brazil is also mapped, and a configuration scheme of a hydrogen production system is discussed. Subsequently, the economic analysis calculates the cost of investment in the alkaline electrolyser of 60 Nm³ / h, similar to the Brazilian bus powered by hydrogen project, coordinated by EMTU. Since the main input of electrolysis is electricity, is analyzed the latest energy auctions of each primary source and it is calculated the cost of production of the wind, solar and hydropower hydrogen. Postponed to this, are investigated the intrinsic environmental impacts of electricity generation process, proposing a readjustment of an indicator of ecological efficiency for the production of hydrogen. Finally, the work discusses the concept of externalities and demonstrates how the incorporation of external costs can leverage the hydrogen economy. In short, it is evident that the wind and hydroelectric hydrogens are more promising compared to solar hydrogen, whether in the economic aspect, because it achieved lower costs, whether in the environmental aspect, because it reached the highest ecological efficiency

Dance-fight-game, art, religiosity, therapy, entertainment, ritual act, in short, "a way of being", are some of the various definitions/qualities attributed to the afro-brazilian cultural manifestation called "Capoeira Angola". Multivocal polysemic in its essence, Capoeira Angola is expressed in different languages which ranges from the types of touches of the musical instruments that make up the orchestra, through different types of songs, until we get the non-verbal communication established by the bodies of "capoeiristas" in the game and/or in the training body situation. The aim of this paper is to think of the line drawing in space, a significant problem in the execution of body movements of this practice. To address the relationship between line, efficiency and aesthetics of body movements, it is developed an ethnography in the Academy of João Pequeno de Pastinha-Sports Center of Capoeira Angola, based on anthropological interpretative approach, in which the concept of culture is semiotic.
