27. Métodos e processos para a análise experimental de sistemas oceânicos de produção de petróleo e gás. / Methods and procedures for the experimental analysis of offshore systems for oil and gas production.
The increasing complexity of o shore system operations for oil and gas production is a reality. Currently, the need to evaluate the seakeeping of these systems requires understanding some phenomena not yet explored and, for that reason, researches using experiments with small scale models become indispensable. Results obtained in model basins require methodo

28. Fracionamento de surfactina em coluna de bolhas e espuma / Fractionation of surfactin on a bubble and foam column
Foam fractionation of biosurfactant surfactin solutions obtained from fermentation with Bacillus subtilis bacteria was experimentally studied. A bubble and foam column system was mounted and operated in a semi-batch mode aiming at to optimize the concentration enrichment and the recovery of the bioproduct. The process involves the injection of gaseous nitrog

32. Crop rotation Scheduling - modeling and solution methodolies / Programação de rotação de culturas - modelos e métodos de solução
Over the last decades, various proposals for techniques and processes to increase agricultural sustainability have been put forward. These proposals bring new planning models in which technical and ecological production aspects must be considered, as well as the access of small farmers to the consumer market. In this type of agricultural production planning,
