13. O Planetário: Espaço Educativo Não Formal Qualificando Professores da Segunda Fase do Ensino Fundamental para o Ensino Formal / The Planetarium: Space Qualified non-formal educational Teachers of the Second Stage of Primary School to formal education
Despite the changes introduced in the Brazilian Educational System since the LDB from 1996, and of the introduction in the PCNs Natural Science of the transversal theme Earth and the Universe, it is still practically null the knowledge of the teachers about the Astronomy concepts presents in the school curriculum, the formal Education scope. This work emphas

14. Simulações Numéricas Tri-dimensionais de Ventos Magnetizados de Estrelas de Baixa Massa / Three-Dimensional Numerical Simulations of Magnetized Winds of Low-Mass Stars
O tópico abordado nesta tese é a perda de massa através de ventos coronais magnetizados em estrelas de baixa massa. Ventos estelares têm sido estudados extensivamente há vários anos, tendo inicialmente como foco o vento solar. Atualmente, sabe-se que o campo magnético é essencial na aceleração e aquecimento dos ventos coronais. Apesar do conhecimen

15. Propriedades físicas de planetas extrasolares
ROTATION is one the most important aspects to be observed in stellar astrophysics. Here we investigate that particularly in stars with planets. This physical parameter supplies information about the distribution of angular momentum in the planetary system, as well as its role on the control of dierent phenomena, including coronal and cromospherical emission

16. Caracterização infravermelho e distribuição espectral de energia para as estrelas com planetas
In this work we study the behavior of the stars belonging to planetary systems in what concern implications its infrared characteristics and the spectral energy distribution (SED). Our study is based on detailed analysis of the behavior on the infrared emission for 48 stars with planets, classied as stars on the main sequence, subgiants and giants. The data

17. Dinâmica de formação planetária no estudo das origens da água de planetas terrestres / PLANETARY FORMATION DYNAMICS IN THE STUDY OF WATER ORIGINS OF TERRESTRIAL PLANETS
Nos estados sólido e gasoso, a água está em toda parte no Universo: nas mais distantes galáxias, entre as estrelas, nas manchas solares, nos planetas, em seus satélites e sistemas de anéis, em asteróides e cometas. Em seu estado líquido, a água tem suma importância no surgimento, desenvolvimento e manutenção da vida terrestre. No estudo de forma�

19. No caminho dos antigos: agricultura de corte-e-queima e intensificação agrícola em populações quilombolas do Vale do Ribeira, SP / On the old onestrack: shifting cultivation and agricultural intensification on quilombola populations at the Ribeira Valley, SP
Slash-and-burn agriculture has been practiced for thousands of years in the forests around the world, especially in the tropics, where it provides for the livelihood of countless poor rural populations. Many studies claim that slash-andburn agriculture is sustainable when performed under conditions of low human demographic density, maintaining or even increa

20. THEOLOGY IN COMPLEXITY: FROM THEOLOGICAL RACIONALISM TO CHALLENGE TRANSDISCIPLINARITY / TEOLOGIA NA COMPLEXIDADE: DO RACIONALISMO TEOLÓGICO AO DESAFIO TRANSDISCIPLINAR
Theology in complexity: seeks review the History´s history. To understand the Reason´s genesis and its development; to understand it exhaustion in the pattern of simplifier rationalism. To perceive the reason´s crisis and the human and world´s consequent agony, the planet´s crisis. To rethink Theology. To understand it in its history function. To verify

21. A ficção científica no Brasil nas decadas de 60 e 70 e Fausto Cunha / Science Fiction in Brazil in the 60 -70 and Fausto Cunha
Science Fiction as a literary gender, has its roots in ancient times, period in which man used to live in a very primitive situation. They were the ancient cavemen who sought for explanations on nature events, which could promote development or destruction of a community. These histories used to be told by someone by a bonfire, inside a cave or in a field. M

22. STOCHASTIC MODELS OF THE FORESTED LANDSCAPES DYNAMICS AND SCENARIO SIMULATION FOR THE STATE OF RIO GRANDE DO SUL, BRAZIL, FROM 1988 TO 2020 / MODELOS ESTOCÁSTICOS DA DINÂMICA DA PAISAGEM FLORESTAL E SIMULAÇÃO DE CENÁRIOS PARA O ESTADO DO RIO GRANDE DO SUL NO PERÍODO DE 1988 A 2020
Land use patterns and the potential careless use of our planets natural resources have recently called the attention of an increasing number of studies in the area of scenario simulation in several parts of the world. The present research aims at simulating the forest scenario of Rio Grande do Sul, Brazil, in order to identify and quantify in a map the fores

23. Définition et implémentation des corrections instrumentales de la mission spatiale CoRoT
CoRoT (Convection, Rotation and planetary Transits) is a space mission conceived to the stellar seismology and the search of extra solar planets. Both scientific programs are based on very high precision photometry and require long and uninterrupted observations. For the study of the stellar oscillations, the instrument must be able to measure periodic varia

24. Aprendizagem por reforço na adaptação a obstáculos em navegação robótica autônoma não-estruturada baseada em imagens / Reinforcement learning for obstable avoidance in image based robotic autonomous non-structured navigation
In the last decades, robotic has become an important role for society, specially in the manufacturing industry. In recent times, applications of mobile robots, from simple toys to planets explorations, has shown how promising will be the use of these tools in a close future. Though, the cost and complexity in developing mobile robots nowadays, which should b
