14. Retransplante de fígado: validação interna de um modelo matemático preditivo de sobrevida / Liver retransplantation: internal validation of a mathematic predictive survival model
Summary: The demands for liver transplantation in various countries have greatly supplanted the offer for this vital organ. In general the survival of re-transplantation patients and of the grafts are smaller than in relation to primary transplantation ones. Therefore, it is important to determine still in pre-operative patients who have a low chance to re-t

18. Interaction Of Learning In Virtual Environments: Footings And Preservation Of Faces In E-Education Forums / Interação em Ambientes Virtuais de Aprendizagem: footings e preservação de faces em e-fóruns educacionais
In this dissertation we study interaction in electronic forums of Virtual Learning Environments (VLE). In other words, we study the interaction in online teaching-learning environments that integrate the virtual distance education modality (ODE). The objective is to understand the impacts of the virtual interaction on the construction of knowledge, based on

24. Análise crítica da utilização de modelagem matemática na avaliação da dispersão de efluentes leves no litoral da Baixada Santista ( Estado de São Paulo). / The analysis of mathematical models in the assessment of effuents dispersion in Baixada Santista coastline (State of São Paulo).
The prediction of the hydrodynamic water circulation and pollutants dispersion, mainly in coastal areas, has been a problem that engineers have been facing. This is due to the increase environmental impacts that involve coastal engineering work and management. The usage of mathematic modeling as assessment tool is necessary for these studies. The main purpos
