1. Frações da matéria orgânica e propriedades redox de substâncias húmicas em sedimentos de oceanos profundos
Previous studies have verified that free radicals such as quinone moieties in organic matter participate in the redox reactions in natural systems. These functional groups were positively correlated with the increase in aromaticity and hydrophobicity of the humic substances. As an alternative to relatively complex and expensive spectroscopic methods, the red

2. Estudo do jateamento em solos argilosos e sua aplicação à engenharia de fundações offshore / Study of water jets in clay and its application to offshore foundation engineering design
Most of all petroleum produced in Brazil is encountered in marine deposits where the water depth may exceed 1000 meters. Recent discoveries of new offshore oil fields have motivated studies in this area designed to develop new techniques applied to oil exploration. For the extraction of oil deposits floating platforms are commonly used, supported by anchorag

3. LOCATION PROPOSAL FOR PETROLEUM PLATFORMS / PROCESSO DE LOCALIZAÇÃO DE PLATAFORMAS DE PETRÓLEO
This paper describes a system for locating oil rigs based on a general location algorithm. The problem consists in maximizing the net present revenue value of the project arbitrating discharge values for each of the production wells involved. Due to the high degree of uncertainty in determining the initial flow rate of each well it is assumed a percentage th

4. Non indigenous ascidians in port and natural environments in a tropical Brazilian bay
Despite limited natural dispersal, some species of ascidians can be transported vast distances via oceanic petroleum platforms, ship hulls and ballast water and therefore may be good indicators of bioinvasion. Usually non indigenous species (NIS) are abundant in harbors. This is caused in part because of the higher propagule delivery rate in these areas. An

5. Offshore women: gender, family and work in womens in male space perception / Mulheres embarcadas: gênero, família e trabalho na percepção de mulheres em espaços masculinos
This dissertation had as objective to examine the relation between women participation in masculine work ambient and gender. Our case study is focused on the research of offshore women, women whose work is executed on petroleum platforms. In this work situation, they leave the daily routine they use to have onshore to spend fourteen days onboard, a place whe

6. Estudo de reatores eletroquímicos para remoção de Cu2+ , Zn2+, Fenol e BTEX em água produzida
The production of water has become one of the most important wastes in the petroleum industry, specifically in the up stream segment. The treatment of this kind of effluents is complex and normally requires high costs. In this context, the electrochemical treatment emerges as an alternative methodology for treating the wastewaters. It employs electrochemical

7. Hydrocarbon Mineralization in Sediments and Plasmid Incidence in Sediment Bacteria from the Campeche Bank
Rates of degradation of radiolabeled hydrocarbons and incidence of bacterial plasmid DNA were investigated in sediment samples collected from the Campeche Bank, Gulf of Mexico, site of an offshore oil field containing several petroleum platforms. Overall rates of mineralization of [14C]hexadecane and [14C]phenanthrene measured for sediments were negligible;
