1. Coeficiente de espalhamento sonoro de painéis perfurados / Scattering sound coefficient of perforated panels
Project studios, concert halls, theaters or places that require quality acoustics for musical activities, require studies on its volume, shape and composition of their surfaces, in order to achieve a place that fulfills its function acoustics. In cases where the volume and shape of these rooms are already defined, it is the acoustic designer to define materi

2. Os processos de (re)estruturação do tecido urbano de Vila Rica: a influência da Igreja Católica
Since the beginning of formation of Ouro Preto (formerly Vila Rica), the Church stood out in the landscape of the camps wich were created there. Simultaneously, the streets (and churchyards / plazas) were then setting, often from the surroundings of these temples. In the first decade of the century, two parishes (known as Nossa Senhora doPilar de Ouro Preto

3. Aspectos dinâmicos de espalhamento caótico clássico / Dynamical aspects of classical scattering
In this thesis we study different scattering systems with chaos. Chaotic scattering, present in a large variety of physical systems, is a type of transient chaos. While the phase-space of such systems is unbounded, irregular motion occurs only in a bounded area, called the scattering region. Still, any (nontrivial) scattering function relating initial condit

4. Formação do epitelio germinativo durante a morfogenese e diferenciação gonodal em Cyprinus carpio (Teleostei:Cypriniformes) : analise estrutural e ultraestrutural das celulas germinativas e somaticas / Formation of germinal epithelium during gonodal morphogenesis and differentiation in Cyprinus carpio (Teleostei:Cypriniformes) : a structural and ultrastructural analysis of the germ and somatic cells
The description of gonadal morphogenesis in Cyprinus carpio provides a new vision of proliferation and differentiation of germ and somatic cells from the gonadal primordium leading to the formation of different ovarian and testicular structures, and the constitution of germinal epithelium which borders the ovigerous lamellae and the seminiferous tubules. In

5. Complexidade dinâmica: água, expansão urbana e espaços livres públicos - o processo de construção da paisagem do Parque Iguaçu - Curitiba - PR / Dynamic complexity: water, urban expansion and public open spaces the process of Iguaçu Park landscape construction, Curitiba-PR.
The process of projecting, building and managing a public urban park, inside an expanding metropolitan area involves a series of factors that should be analyzed under various points of view. Contemporary society has been through intensive changes within the last 40 years. Urban population has surpassed rural, establishing a new way of life; greater attention

6. Construções genéricas de espaços de Asplund C(K) / Generic constructions of Asplund spaces C(K)
In this work we consider a method of generic constructions of compact scattered non-metrizable spaces developed by Baumgartner, Shelah, Rabus, Juhasz and Soukup. We introduce new techniques and obtain new applications both relevant to topology of compact spaces and the geometry of Banach spaces of continuous functions. The new techniques concern new amalgama

7. Formação por competencias : do prescrito ao real / Formation for abilities : of the prescribed to the real
This current research is an analysis of the process of implementing competence orientation in state (public) schools situated in São Paulo metropolitan area. The analysis took place in the first half of the 2000?s and aimed at understanding the changes inserted in the educational system throughout the last two decades. The hypothesis for the research is tha

8. Microscopia de força atômica in-situ de superfícies de membranas poliméricas de Nafion com nanopartículas de sílica incorporadas / Atomic force microscopy in-situ of polymeric Nafion membrane surfaces with nanoparticles of incorporated silica
Fountains of renewable energies are occupying an important space in scientific inquiries. Within this Proton Exchange Membrane Fuel Cells (PEMFC) stand out. Studies show that the elevation of PEMFCs operation temperature results in the increase of its efficiency. Nevertheless, in these work conditions there appears to be a necessity in improving electrolyte

9. As múltiplas vozes constitutivas do personagem-escritor no romance A Festa de Ivan Angelo
The present study aims to reveal the formation of the writer-character on the novel The Party, by Ivan Ângelo. In order to develop the analysis, the various voices which permeate the story are taken as reference, considering the socio-historical and ideological relations inherent to the process of formation of the writer-character on the different positions

10. The Places of Urbanization - the hinterland of Rio de Janeiro State" / Os lugares da urbanização - O caso do interior fluminense.
The main concern of this work is to study recent urbanization processes in Rio de Janeiro s hinterland, conceiving urbanization as a crucial factor for territorial structuring, which transcends at the present time the agglomeration physical boundaries. Rio de Janeiro s hinterland recent urbanization trends have been evaluated through the combination of three

11. Interactions among rods in the isolated retina of Bufo marinus.
1. The existence and extent of interactions among rods were analysed in the isolated retina of Bufo marinus. Intracellular recordings were made from the outer segments with micropipettes. Stimuli of precisely measured geometry were delivered to the outer segments using a compound microscope. 2. To demonstrate the existence of interactions two rods were simul

12. Hessian eigenmaps: Locally linear embedding techniques for high-dimensional data
We describe a method for recovering the underlying parametrization of scattered data (mi) lying on a manifold M embedded in high-dimensional Euclidean space. The method, Hessian-based locally linear embedding, derives from a conceptual framework of local isometry in which the manifold M, viewed as a Riemannian submanifold of the ambient Euclidean space ℝn,
