25. Identificação e avaliação de variáveis críticas no processo de produção da cana-de-açúcar / Identification and evaluation of the critical variables in the sugar cane production process
Sugar cane is one of the cultures more important economically in Brazil, which is at the same time the leading producer and exporter in the word. The perspectives for the next few years are expansion of cultivated area in order to attend the demand, mainly the international market. Besides the increasing of production, giving the expansion of cultivated area

26. Optimization of pipeline scheduling operations: efficient formulations and hydraulic considerations. / Otimização da programação de operações dutoviárias: formulações eficientes e considerações hidraúlicas.
Pipeline systems correspond nowadays to the most efficient mode for the transportation of large amounts of liquid and vapor products for long distances. Pipelines are utilized by the Petroleum Industry to transport petroleum and its product derivatives. The present work addresses the scheduling of pipeline distribution of a system that operates with a pipeli

27. "Utilização do método dos povoamentos na caracterização de comunidades bentônicas em trecho do infralitoral consolidado da Enseada das Palmas, Ilha Anchieta, Ubatuba (SP)" / Settlements method for the characterization of hard bottom benthic communities in an infralittoral stretch in Palmas Bay, Anchieta Island, Ubatuba (SP)
The biodiversity characterization of benthic communities in the Brazilian coast is limited to a few works, which studied an area of about 3,400 m2. The objective of this study was to propose a new method, unprecedented in hard bottom marine communities, based in the sampling of landscape heterogeneity units, named physiognomies and settlements, aiming at an

28. REPETRO - Regime Aduaneiro Especial de Importação e Exportação de Bens Destinados à Pesquisa e Lavra de Petróleo e Gás: Análise dos Entraves e Propostas de Soluções
REPETRO, the special tax regime for importing and exporting goods for the exploration and drilling of oil and gas, aims at bringing foreign assets to Brazil enjoying a suspension or even an exemption of taxes, so that Brazilian industry may profit from about 8 billion American dollars in investments. The creation of normative devices as well as the managemen

29. Projeto e simulação de um controle discreto para a plataforma multi-missão e sua migração para um sistema operacional de tempo real / Design and simulation of a discrete controller for the multi-mission platform and its migration to a real time operational system
This work uses the concepts of visual modeling, automatic code generation and code migration to real time operational systems. As a study case, a three axis stabilized artificial satellite with fine pointing was used, in its nominal operational mode. The dominance of this kind of technology will make it possible to Brazil, through the National Institute of S

30. Multimodal vibration damping through piezoelectric patches and optimal resonant shunt circuits
Piezoelectric elements connected to shunt circuits and bonded to a mechanical structure form a dissipation device that can be designed to add damping to the mechanical system. Due to the piezoelectric effect, part of the vibration energy is transformed into electrical energy that can be conveniently dissipated. Therefore, by using appropriate electrical circ

32. Estudo do comportamento do coeficiente de desgaste e dos modos de desgaste abrasivo em ensaios de desgaste micro-abrasivo. / Wear coefficient and wear mode transition study in micro-abrasive wear testing.
This work presents a study on the behavior of different materials under the action of micro-abrasive wear. A micro-abrasive wear testing machine with fixed sphere was designed and constructed, presenting a mechanical configuration with differences with respect to those found in the literature (Gee et al., 2005). M2 tool steel and WC-Co P20 were used as testi

33. Quadro de horários acadêmico:: uma abordagem com foco na avaliação institucional e na gestão de custos de instituições de ensino superior privadas brasileiras
This dissertation presents the timetabling problem to educational institutions showed in a different angle in relation with other works in the literature, applicable in the brazilian context. The construction of academic timetables is a structural activity in an educational institution. There are rules and standards in the brazilian superior education system

34. ENTRE O DISCURSO E A PRÁTICA: HÁ REFORMA? UMA REFLEXÃO SOBREPRÁTICAS INTERVENTIVAS DE CUIDADO NA CLÍNICA DA SAÚDE MENTAL / BETWEEN THE SPEECH AND THE PRACTICES A REFLECTION ABOUT INTERVENTION IN THE CARE PRACTICES IN MENTAL HEALTH CLINIC
The purpose of psychiatric reform is to introduce a radical change in asylum practices. This means the reform adopted another form of thinking madness, psychic suffering and assistance/care; in other words, it means build new paradigms and new references to guide the interventions in mental health. The compromise with reform´s logic implies in a constant ex

36. Optimization of the process of concentration of vitamin e from DDSO using supercritical CO2
The objective of this work was the scientific development of concentration of vitamin E from deodorizer distillate of soybean oil (DDSO) using supercritical CO2. Vitamins and sterols rare produced synthetically, but recently the interest in their extraction from natural sources has increased. Therefore, the motivation behind this work was to concentrate the
