1. Simulação hidrológica de rios com grandes planícies de inundação
Besides understanding the current hydrologic behavior of a river and floodplain drainage system, it is important to be able to predict its future conditions in light of possible impacts due to anthropogenic activities and climate variability. Mathematical modeling is the ideal tool for this purpose. For large scale hydrologic systems, if the objective is to

2. Estudo da degradação de hidrocarbonetos policíclicos aromáticos a partir da reação de fenton utilizando magnetitas dopadas com cobalto
The awareness regarding Polycyclics Aromatic Hydrocarbons (PAHs), petroleum derivatives, has been increasing over the years due to their toxic, carcinogenic and mutagenic characteristics. The increase on the use of petroleum and its derivatives as energy source has induced many accidents spilling liquid effluent in the environment, making harm to biota, incl

4. FLUX AND TRANSPORT STUDY OF PURE GASOLINE AND GASOLINE BLENDED ETHANOL IN UNSATURATED POROUS MEDIA / ESTUDO DO FLUXO E TRANSPORTE DE GASOLINA PURA E MISTURADA COM ETANOL EM MEIOS POROSOS NÃO SATURADOS
The subsurface release of water immiscible pollutants (NAPLs) due to leaks in storage tanks or pipelines and spilling transportation accidents is of great concern, since the NAPL or its constituents may migrate through the vadose zone until reaching the water table and eventually contaminate clean water sources. In Brazil, most of the gas stations store etha

5. Influência do deságue do sistema de lagoas de estabilização na quantidade de nutrientes no Igarapé Grande, Boa Vista, Roraima
The Igrarapé (small streams) Grande, in Boa Vista, Roraima, is the receiving body of the wasterwater generated starting from the waste stabilization ponds, system of treatment of the sanitary sewers of part of the city. By the hypothesis that the spilling of those wasterwater in referred him body of water contributes so that the same presents physiochemical

6. O sonho de Descartes: o homem das paixões
This dissertation is an audacious proposal to closely examine the personality of René Descartes which could perhaps, lead us to a theory about his mission in life which is intimately fused with his philosophy. The complexity of his psyche as revealed by his first biographer Baillet is expressed in the progression of his writings. We have chosen our course o

7. Estudo da dinâmica costeira da região da foz do rio Piranhas-Açu para geração de mapas de sensibilidade do litoral ao derramamento de óleo
The study area is located in the northern coast of Rio Grande do Norte State comprising the mouth of Açu-Piranhas river including the cities of Porto do Mangue e Areia Branca. The local geological setting comprises Cretaceous, Tertiary and Quaternary geological units of the Potiguar Basin. One is about a region of high morphologic instability due to action

8. ADSORÇÃO DE UM ÁCIDO GRAXO UTILIZADO EM FLOTAÇÃO POR VERMICULITA HIDROFÓBICA
In this work are presented studies to evaluate the adsorption capacity of the expanded vermiculite mineral and of the vermiculite hydrophobized mineral originating from the states of Piauí and Goiás with different size. Tests of adsorption were accomplished in direct contact systems with oil, contact with solution oil-water that simulates oil spilling in t

10. DistribuiÃÃo espacial e sazonal da composiÃÃo e biomassa fitoplanctÃnica correlacionadas com a hidrologia do estuÃrio do rio Timbà (Paulista, Pernambuco)
This study was carried out at the Timbà River estuary of which the hydrographic basin includes the municipalities of Paulista, Abreu e Lima and Igarassu (7Â30â and 8Â05âS Lat. - 34Â45â and 35Â10âW Long.), at the north littoral of Pernambuco State. In this area, intensive fisheries activities are under strong anthropogenic pressure, mainly due to spi

12. Mapeamento da sensibilidade ambiental ao impacto por óleo de um segmento da costa entre os estados do Rio Grande do Norte e Ceará utilizando imagens ETM+/LANDSAT 7 e geoprocessamento / Mapping of the coastal environmental sensitivity to oil spill between Rio Grande do Norte and Ceará states using Landsat 7/ETM+ images and geoprocessing
Acidentes com óleo no mar são freqüentes, causando diversos impactos ao ambiente e comunidades biológicas, além de prejuízos socioeconômicos. Mapas de sensibilidade ambiental ao derramamento de óleo são componentes indispensáveis dos planos de contingência e resposta emergencial à este tipo de acidente. Os mapas de sensibilidade trazem informaç�
