1. Experimental and numerical evaluation of viscoelastic sandwich beams
Abstract Viscoelastic materials can dissipate a large amount of energy when subjected to cyclic shear deformations, but they have low bearing capacity. Therefore they are often employed as a damping layer in sandwich structures. These sandwich structures present a high damping ratio and simple application. In order to design sandwich structures, many aspects

2. Pensando em sistemas : abordagens do sistema internacional
O debate acerca do sistema internacional é central à teoria das relações internacionais. Constitui-se também como ponto fundamental ao estabelecimento da própria disciplina de Relações Internacionais em torno de um objeto de estudo consolidado. No entanto, o que se percebe é o desenvolvimento de abordagens concorrentes do termo, de modo que resultam

3. Paths of knowledge: reflections upon the complex thought, temporality and a buddhist experience / Caminhos do conhecimento: reflexões sobre o pensamento complexo, a temporalidade e uma experiência budista
The main purpose of this thesis is to invite to a reflection on anthropology in light of the major paradigm shifts that have taken place in the hard-science core. I begin by relating the establishment of social sciences as from the Illuminist context, which imprinted their main characteristics concerning reality model, methodology and principles. I subsequen

4. JUSTIÇA TRANSFRONTEIRIÇA: UMA ANÁLISE COMPARATIVA DAS ESTRUTURAS JUDICIAIS E MECANISMOS DE COOPERAÇÃO JURISDICIONAL EM MATÉRIA CIVIL E COMERCIAL ENTRE MERCOSUL E UNIÃO EUROPÉIA
This work approaches Cross-Border Justice as an instrument which affirms rights internationally. In facing the infinite multiplicity of juridical mechanisms which correspond to this paradigm, there arose the necessity to elect those which would be covered by this investigation, with the corresponding exclusion of all other possibilities. Before such an impos

5. Planejando para a incerteza: a gestão do complexo nas organizações
Time and complexity are in the roots of the contemporary thinking and new thoughts on new sciences. ln natural sciences inserting the concept of time as the fundamental element to the understanding of complex phenomena, dissipative structures and uncertainty at the material leveI raised a new pattern to the knowledge about life evolution and to inserting the

6. Stochastic Molecular Dynamics of colloidal particles
Colloidal particles move in the carrier liquid under the action of several forces and torques. When the particles carry a dipole moment, electric or magnetic, as in ferrofluids, the rotational and translational motions are coupled because the field on a particle depends on the spatial and directional distribution of the others and the force and torque on it

7. SANDY BEACH MORPHODYNAMICS AND MACROBENTHIC COMMUNITIES IN TEMPERATE, SUBTROPICAL AND TROPICAL REGIONS - A MACROECOLOGICAL APPROACH
A comprehensive study involving 52 microtidal beaches spanning from reflective to dissipative states and located in tropical, subtropical and temperate regions in the Atlantic, Pacific and Indian oceans was carried out to unravel the relative roles of latitude and beach morphodynamics in determining beach macrobenthic species richness, abundance, biomass and

8. Investigações sobre as relações de escala dos sistemas estelares auto-gravitantes / Investigations on the scaling relations of self-gravitating stellar systems
We aim in this work to collect several numerical and analitical investigations concerning the origin of the scaling relations of the self-gravitating stellar systems. These relations depend on a very small number of independent physical parameters that reduce and confine the observational constraints to a plane in this parameter space, called the ""Fundament

10. Ordem e caos em plasmas magnetizados
The objective of this thesis is to present a clear understanding of some important nonlinear phenomena that are common in space and laboratory plasmas. Specifically,the present analytical and numerical studies have focused on the properties of electromagnetic turbulence as well as associated coherent structures and chaotic behaviors in a multi-component magn

11. Gravitational symmetry breaking in microtubular dissipative structures.
Reduction-diffusion theories can account for both morphogenesis and the sensitivity of biological systems to weak fields. They predict that gravity can cause the symmetry breaking that is necessary for pattern formation. Microtubules play an important role in organizing the cell, and recent studies hae shown that they can form in vitro dissipative structures

12. Dissipative Structures, Catastrophes, and Pattern Formation: A Bifurcation Analysis
A model chemical network involving reactions and diffusion is studied. Spatially and temporally ordered solutions of the equations are found by bifurcation theory. These solutions are calculated analytically and their stability is studied. Properties of these dissipative structures are discussed, and a comparison with Thom's theories of morphogenesis is outl
