1. Estrutura de classe e mobilidade social no processo de inserção profissional de jovens no Brasil: reflexões e agenda de pesquisa
Resumo Diante do contexto de aumento do número de matrículas no Ensino Superior brasileiro e do discurso organizacional de falta de mão de obra qualificada no mercado de trabalho brasileiro, cresce a importância de estudos acerca de inserção profissional no país. Contudo, grande parte dos já existentes se refere a pesquisas empíricas, sem contemplar

2. Study of water entry of circular cylinder by using analytical and numerical solutions
Water impact phenomenon in the case of a circular cylinder is an important issue in offshore industry where cross members may be in the splash zone of the incident wave. An analytical method as well as a numerical solution are employed to study the water entry problem of a circular section. The procedure for derivation of the analytical formulas is demonstra

3. Aspectos contábeis do Tratado de Itaipu : análise das práticas de avaliação dos ativos imobilizados da empresa Itaipu Binacional
In the seventies of the twentieth century, there was an expansion in the production of electricity in Brazil. On April 26, 1973 the Itaipu Treaty was concluded between Brazil and Paraguay which enabled the construction of a hydroelectric plant in the border between the two countries: the Itaipu Binacional, which is governed by the Itaipu Treaty and its Annex

4. A conjectura de Zariski para a multiplicidade
In his retiring Presidential address to the American Mathematical Society in 1971, Zariski proposed some questions in the Theory of Singularities. One of them concerns the topological invariance of the multiplicity of complex hypersurfaces. In more accurate terms, Zariski asked: if two complex hypersurfaces are homeomorphic as embedded varieties, then are th

5. Fundos constitucionais e Banco do Nordeste: uma análise das liberações considerando a lógica de operação do sistema bancário nacional
The aim of these lines is to analyze the foundations of the development of the Brazilian North and Northeast regions. We will consider the singularities of the cities of these regions. To accomplish that goal, the text is divided in five chapters. The first chapter will revise the concept of a monetary theory of production, so that the decision of the econom

6. Curvas nodais maximais via curvas de Fermat
We study the rational projective nodal plane curves in the projective plane P2(C) by using the Fermat curve Fn : Xn+Y n+Zn = 0. We deal with the theory of dual curves in the projective plane and a special type of group action of Zn x Zn on the Fermat curve and its dual to construct, for any positive integer n maior ou igual a 3, a rational nodal plane curve

7. Aspects of nonrelativistic quantum gravity
A nonrelativistic approach to quantum gravity is studied. At least for weak gravitational fields it should be a valid approximation. Such an approach can be used to point out problems and prospects inherent in a more exact theory of quantum gravity, yet to be discovered. Nonrelativistic quantum gravity, e.g., shows promise for prohibiting black holes altoget

8. Stiffness Study of Closed Kinematics Chains / Estudo de rigidez de cadeias cinemáticas fechadas
Multibody systems consist on a kinematic chain composed of links that can be rigid or flexible, interconnected by joints. The multibody systems are of great importance and are used in various applications such as in aerospace and automobile engineering, machine tools, mechanisms, sea exploration, medicine and robotics. An example of multibody system that has

10. Culture and schooling institutions: domination, organization, management processes and teaching practices / Cultura e instituição escolar: os processos de dominação e a organização, a gestão e as práticas docentes
Taking part of the research line State and educational policies of Post-graduate program in education of Federal University of Goiás (UFG), Brazil, this work analyzes the interference of cultural dimensions with inner dynamics of schools, putting out its implications on organization, management and effectiveness of teachers work. Further, the investigation

11. A dinamica por tras da sequencia espectral / The dynamic behind the spectral sequence
In this work, we present an algorithm for a chain complex C and its di_erential given by a connection matrix which determines an associated spectral sequence (Er, dr). More specifically, a system spanning Er in terms of the original basis of C is obtained as well as the identi_cation of all di_erentials dr p : Er p ! Er p?r. In exploring the dynamical implic

12. TÓPICOS EM TEORIA DE MATHER / TOPICS IN MATHER THEORY
Seja (Es)t o espaço de germes na origem de funções suaves entre os espaços euclidianos de dimensões e t. Nesta dissertação, apresentamos a parte da Teoria de Mather que descreve hipóteses suficientes para k-determinação em (Es)t sob duas ações diferentes, induzindo as chamadas R- e K-equivalências. Um germe é k-determinado se é equivalente a q
