Evolução tectônica do Trend Badejo-Linguado-Pampo, bacia de Campos (RJ)

The regional geological work for the oil industry, in order to find potential areas for hydrocarbon exploration and understand the geological parameters responsible for the formation of the deposit are known importance. This work fits into that scenario, with regional research with the aid of wells and 2D and 3D seismic sold by DBEP (Database Exploration and Production). Were also used as GeoGraphix software package Landmarks modules Prizm and SeisWork 2D and 3D, and the Surfer 8 and ArcGIS 9.2 with the infrastructure provided by the 05 PRH - ANP with LSGI (Laboratory of Seismic and Geological Interpretation) located at UNESP -- Campus de Rio Claro. The work focuses on study the trend of oil-Badejo-Linguado-Pampo, producing fields since the beginning of offshore holdings. The Campos Basin is now known as the offshore basin of the country more productive, and the high structural Badejo is a structure of great importance in the basin presents itself as largely responsible for the conditioning of hydrocarbon fields Pampo, Linguado and Badejo. Therefore this work also aims to increase knowledge of the region in terms of tectonic and stratigraphic characterize the geometry of the structures associated with this major regional structure. For this we used structural contour maps of the main chrono-horizons, and Isopach maps for the purpose of better understanding the tectono-sedimentary evolution of the Campos Basin locally.

Geologia do alvo e da mina Sol Nascente, município de Rio Crespo, Rondônia

Eight Mesoproterozoic granite suites are recognized in the Rondônia Tin Province, called Serra da Providência Intrusive Suite (1606-1532 Ma), Rio Crespo Intrusive Suite (1500 Ma), St. Anthony Intrusive Suite (1406 Ma), Teotonio Intrusive Suite (1387 Ma ), Santa Clara Intrusive Suite (1082-1074 Ma) and Younger Granites of Rondônia Intrusive Suite (998-974 Ma), represent successive magmatic type A (anorogenic) and the intra-plate basement rocks intruded in the metamorphic complex named Jamari separated into two distinct lithologic associations, a ortogneiss (U-Pb from 1.76 to 1.73 Ga) and a paragneiss (1675 + / - 12 Ma). Tin mineralization are widely found in the Tin Province and are associated with granitic intrusions known Mesoproterozoic more closely with the last two magmatic events, represented by the Santa Clara and Younger Granites of Rondônia. The tin mineralization are of primary and secondary, with the primary form deposits of different structural styles and is presented in the form of endo-or exogreisens, veins, stockworks and pegmatites. The secondary mineralization are related to natural processes of weathering and erosion of primary rocks, leading to placer deposits classified as colluvial, eluvial and colluvial-alluvial. The Target Alvo Sol Nascente is located in the central-eastern Rondônia Tin Province and has basement rocks of the metamorphic-magmatic region represented by Jamari Complex intrusive suites and Sierra Providence and Rio Crespo. The last tectonic event spa in the area was responsible for the intrusion of Younger Granites of Rondônia (São Carlos and Caripuanã Massifis). The anomalous levels of tin, sufficient to operate (Mina Rising Sun), indicate that there was possibly mineralization event, evidenced by pegmatite veins well defined, easily found relatively close to mine. Plaque deposits associated with Quaternary sedimentary sequences can also be observed

Preparação e caracterização da casca de banana prata particulada para aplicação com reforço em compósito de matriz de PEAD

The waste, exaggerated and incorrect disposal of biomass are common practices in modern times where everything is disposable. However the growing concern with the nature and the environment compel man to give nobler destinations for these products through sustainability and recycling of waste. Banana peel is a residual biomass, which is not consumed. It generates tons of waste per week in São Paulo city. This trash is disposed in dumps and landfills, which could be reduced by using it as reinforcement in natural composites. The high density polyethylene (HDPE) is a polymer derived from the ethylene polymerization and is easily recycled. Which makes it a sustainable material. In the present work characteristics of the natural composite composed with banana peel and high-density polyethylene were studied. It was noted that removing the lignin present in the banana peel, the fiber introduces a significant improvement in thermal resistance. The preparation of composite was made with a ratio of 5% and 10% of reinforcement in comparison with polymeric matrix mass. Composites were thermally, mechanically and microscopically characterized. The addition of fiber in the polymer increased the mechanical strength of the composite. The fiber surface treatment with distilled water removed the amorphous material present in the fibers, improving significantly thermal stability and increasing crystallinity of the celullose. The addition of 5% fiber in mass to the polymer increased significantly the tensile strength and elasticity modulus for the composite. With 10% of fiber addiction there were also an improvement when compared with pure HDPE, but when compared with 5% composite the mechanical properties are slightly lower. This may be due to the fiber particle size, which are small and eventually become a hub of tension ... (Complete abstract click electronic access below)

Aplicação de coagulantes naturais no tratamento de lixiviado de resíduos urbanos

With the constant increase in the municipal solid waste (MSW) generation, mainly due to the high consumption patterns, it becomes difficult to manage correctly the solid waste and thus minimize their impact on the environment. One of the most problems of the large amount of waste generated is the liquid originated from physical, chemical and biological decomposition process of organic wastes, with dark color and bad smell, called leachate: it can reach the soil, polluting the groundwater and the surface water. Therefore, this study aimed to investigate the process of coagulation/flocculation/sedimentation applied in the treatment of the leachate generated in the not controlled landfill of Presidente Prudente, Sao Paulo...

Variação temporal e espacial da taxa de sedimentação e das características limnológicas na microbacia do córrego da Barrinha, no município de Pirassununga, SP

Studies regarding the quality and quantity of water have become more and more important because of the increasing negative environmental impacts occurred and their scarcity increase as well. At the Center of Tropical Fish Research (Centro de Pesquisas de Peixes Tropicais - CEPTAlIBAMA) located in the city of Pirassununga, SP, there is a dam named Represa Velha which supplies 128 tanks that are fish hatcheries. This dam takes in part of the Barrinha stream micro-basin where it has been observed strong impacts due to the deforestation of its support forest, as well an the intensive agricultural activities in the neighboring areas. There has been established and distributed 13 points of water-collectors disposed inside the stream and the dam. The water samples were taken from the stream only from its surface because of the low depth and, inside. In the dam, the water samples were taken at the water column, at a 50cm distance over the sediment. In every point of collection inside the dam, it was placed a chamber of sedimentation, vertically in the water column at a 70% height from the total depth. The collections took place during the dry/cold and raining/warm periods of the years 2000 and 2001. Then, it were analyzed the physical, physical-chemical, chemical and micro-biological parameters of the water samples. The obtained results were statistically analyzed throughout the SAS system (Statistical Analisys System). Parameters such as total phosphate, nitrate, nitrite and turbidity were within the established limits for the Class 2 water, according to the n° 20/1986 CONAMA Resolução. However, the total and Escherichia coli coliforms, mainly inside the Barrinha stream, had showed values above of the established limits for the same...

Influência da restrição calórica materna moderada sobre o metabolismo energético em ratos Wistar

Estudos em humanos e animais têm demonstrado que a nutrição inadequada em fase crítica de desenvolvimento, como na gestação, pode causar alterações da prole na vida adulta. Tais estudos levaram à proposição da hipótese de programação fetal, segundo a qual o risco para desenvolver certas doenças é função não apenas da carga genética ou dos hábitos de vida do indivíduo adulto, como também da atuação de fatores ambientais em períodos críticos. O objetivo deste trabalho foi avaliar o efeito tardio da restrição calórica materna moderada (30%), na gestação e/ou lactação sobre o metabolismo energético da prole. Foram utilizados ratos Wistar, sendo os grupos experimentais divididos da seguinte forma: NN (filhotes nascidos de mães normais e colocados em gaiolas com mães do grupo normal na lactação), NR (filhotes nascidos de mães do grupo normal e colocados em gaiolas com mães restritas na lactação), RN (filhotes nascidos de mães restritas na gestação e colocados em gaiolas com mães normais na lactação) e RR (filhotes nascidos de mães restritas na gestação e colocados em gaiolas com mães restritas na lactação). Foram avaliados o peso corporal, a ingestão de alimentos, os depósitos de gordura, o índice de adiposidade, lipídios plasmáticos, gordura hepática e gordura da carcaça.. A restrição nutricional materna provocou alterações significativas tanto em machos quanto em fêmeas no período do desmame, entretanto no início da idade adulta somente os machos apresentaram mudanças mais expressivas no metabolismo energético e no desenvolvimento corpóreo. Houve uma redução no peso corpóreo dos animais machos dos grupos NR, RN e RR (8,9%, 9,0% e 14,2%, respectivamente). No entanto, somente os grupos NR e RR apresentaram diminuição nos teores de gordura hepática e triglicerídeos plasmáticos. O fornecimento de dieta ad libitum na lactação às mães com ...
