1. Conocimiento Especializado del Profesor de Matemáticas acerca del Infinito
Abstract Infinity is a concept underlying many concepts present in school mathematics. In this article, we explore teachers' knowledge about infinity from the perspective of the professional knowledge, which is used to deal with infinity in a classroom. For that purpose, we use the discussion of vignettes of simulated situations where different kinds of unde

2. Controle ativo de vibrações em estruturas flexíveis com incertezas paramétricas / Active vibration control of flexible structures with parametric uncertainties
The aim of this dissertation is to study the H-infinity robust control techniques for linear dynamic systems with parametric uncertainties. The finite element method was employed to find the model of the flexible structure. When dealing with the model, parametric uncertainties were considered for natural frequencies and for damping of the structure. The para

4. O nÃcleo do calor em uma variedade riemanniana / The heat kernel on a Riemannian manifold
In a connected and compact Riemannian Manifold we will introduce the concept of spectre of Laplace operator. Using the existence and unicity of the heat kernel in Riemannian manifold we proof the Hodge composition theorem. This theorem states that the Hilbert space L2(M, g) decompose in direct sum of subspaces with finite dimesion, where each subspace is the

5. AT THE BORDELINE OF THE OTHER: ANTROPOPHAGIC UPRISINGS / NA FRONTEIRA DO OUTRO: MOTINS ANTROPOFÁGICOS
This essay-thesis comes from my restlessness about the way the relationship between me and the others , between the subject and the object, insummary, between the subjectivizing process of the modernity / coloniality and the alterity or other non occidental gnosiologies. How to behave in front of the other ontologies, other epistemologies and other ethics wh

6. O inato e o apreendido : a noção de habitus na sociologia de Pierre Bourdieu
In search of a wider elucidation, concerning a concept of basis to contemporary Sociology, the work goes through an exegetical way around the idea of habitus, from the contribution made by the French sociologist Pierre Bourdieu. Counted as one of the most remarkable sociologists th of the 20 Century, Bourdieu has established his work, which is still deeply i

7. O conceito de amor em Emmanuel Lévinas
The ethic discussion in the last time has roused a great interest in many thinkers such as Ernest Thungendart, Jurgen Habbermas, Jacques Derrida, Rosmini, Bonhoefer, Guardini, Mancini. They try to put out this discussion at the present day, beside the new philisophic tendencies as: Language Philosophy, Knowledge Theory and Politic Philosophy. Among these thi

8. Subjetividade como responsabilidade em Levinas: quando a alteridade atravessa o sujeito
This paper examines the description made by Levinas of subjectivity as responsibility, based on two works: âTotalità et Infiniâ (1961) and âAutrement quÂÃtre ou au-dela de lÂessence (1974), and has as an axis the notion of infinity as an ideatum that goes beyond the idea that considers it. The philosopher defines Ethics as âphilosophy firstâ, by see

9. Logica positiva : plenitude, potencialidade e problemas (do pensar sem negação)
This work studies some problems connected to the role of negation in logic, treating the positive fragments of propositional calculus in order to deal with two main questions: the proof of the completeness theorems in systems lacking negation, and the puzzle raised by positive paradoxes like the well-known argument of Haskel Curry. We study the constructive

10. Ecological systems and the concept of biological organization
An axiomatic system is proposed to improve identification, description, and analysis of complex ecological systems. Such systems are assumed to be organized and have structure. Organization is the complex of interactions and properties of structure that make the perpetuation of structure possible. An entity of structure is assumed to be composed of other ent

11. Magnetofluid-Dynamic Spectrum and Low Shear Stability*
For a perfectly conducting, cylindrical plasma equilibrium (“screw-pinch”), the spectrum contains four distinct continua, three of which can extend to the origin. This implies the existence of irreversible damping and heating in the nondissipative model. The continuum becomes (Suydam) unstable by instantly shedding an infinite number of point eigenvalues

12. Phase I study of multiple-dose cefprozil and comparison with cefaclor.
The objectives of this study were to assess the safety and tolerance of cefprozil, to characterize the pharmacokinetics of cefprozil after administration of multiple doses of the drug, and to compare these pharmacokinetic parameters with those obtained with cefaclor. The volunteers received 28 doses of 250, 500, or 1,000 mg of cefprozil or 500 mg of cefaclor
