1. Análise do modelo de mistura aplicado em escoamentos isotérmicos gás-líquido / Analysis of mixture model applied in gas-liquid isothermals flows
Gas-liquid flows are often found in nature as well as in various industrial applications. In the oil production, for example, in natural or artificial lift systems (continuous or intermittent gas-lift), gas and oil flow simultaneously in pipes. The prediction of gas-liquid behavior becomes necessary for technical and economic viability of many industrial pro

2. Lógica e técnica na redução fenomenológica : da filosofia à empiria em psicologia
O presente trabalho tem como objetivo investigar as aplicações do método fenomenológico à pesquisa empírica em psicologia. O foco da investigação é o passo reflexivo designado redução fenomenológica, considerado elemento fundamental da identidade analítica na tradição da fenomenologia. O trabalho foi dividido em três estudos. O Estudo I trato

3. Atenção para tarefas simples e complexas nas perspectivas de primeira e terceira pessoa : um experimento fenomenológico / Attention to simple and complex tasks in the perspectives of first and third person: a phenomenological experiment
Compara-se o desempenho atentivo entre tarefas moleculares (foco em tarefas simples e reduzidas), para as quais o sentido é uma atribuição externa, com tarefas molares (foco em tarefas complexas que requerem apreensão abstrata e global), para as quais o sentido é uma atribuição interna. A pesquisa foi organizada em três estudos. No primeiro, exibiu-s

4. Entre cinema e videoarte : procedimentos disjuntivos de montagem e narrativas sensoriais
The present research is the analysis of the procedures involved in creating video works and video installations produced between 2004 and 2008. The appreciation of sensory aspects of the image - the descriptions of space and landscape that appear in several videos of that period - transforms the relationships between space and time in these narratives, which

5. Charm production in neutral current neutrino-nucleus scattering within the color dipole approach
The rate for inclusive charm production in neutral current neutrino-nucleus interactions is calculated. The interaction of high energy neutrinos on hadron targets is an outstanding probe to test Quantum Chromodynamics (QCD) and shed light in the understanding of the parton properties of hadron structure. We have considered the QCD color dipole picture for su

6. Phenomenology of infrared finite gluon propagator and coupling constant
We report on some recent solutions of the Dyson-Schwinger equations for the infrared behavior of the gluon propagator and coupling constant, discussing their differences and proposing that these different behaviors can be tested through hadronic phenomenology. We discuss which kind of phenomenological tests can be applied to the gluon propagator and coupling

7. Physics Beyond Standard Model in Theories with Extra Dimensons / "Física além do modelo padrão em teorias com dimensões extras"
The goal of this dissertation is to study theories that use extra dimensions to solve the problems that appear in the Standard Model at energies of the order 1 TeV. Specifically, we worked with models with more than 4 dimensions, where the spatial dimensions are compactified in an S1/Z2 orbifold. The Standard Model agrees to a great degree with the experimen

8. Filtros de spin não-magneticos controlados por voltagem / Voltage controlled non-magnetic spin filters
The aim of this work was to study the transport properties of nonmagnetic semiconductor heterostructures: double barrier diodes ? DBD. Our attention was focused on the carrier spin polarization through the structure. First we present the phenomenology behind the carrier transport and how the DBD can act as a spin filter. In the sequence, we present the exper

9. Introdução a fenomenologia da oscilação de neutrinos, no vacuo e na materia / Introduction to neutrino oscillation s fenomenology, in vacuum and matter
The subject of this work is to produce a didactic text that can be used by physics students as a basis when incoming on the neutrinos phenomenology area. We introduce the neutrinos mixing model in vacuum, based on the concept of state superposition. We show that this hypothesis leads to avor oscillation phenomenon, the one is proposed to be a solution to the

11. Efeito da Hipertensão Intracraniana sobre a complacência Gástrica de ratos Anestesiados: Cauterização do Fenômeno e dos Mecanismos Neurais / Effect of the intracranial hypertension on gastric compliance of anaesthetized rats: characterization of the phenomenology and neural mechanisms
In humans, intracranial hypertension (ICH) disturbs cardiovascular function and also modifies gastrointestinal physiology as clinically manifested by nausea and vomiting symptoms. Since gastric compliance drives the gastric emptying of liquid which is inhibited by ICH, it was studied the ICH effect on gastric compliance behavior in anesthetized rats and the

12. Taking care for a mental handicapped son: clearing up parents experiences of their being-with-the-son. / "Cuidando do filho com deficiência mental: desvelamentos de viviências de pais no seu ser-com-o-filho"
This work emerged from my disquiet about the meaning given by parents upon caring for a mental handicapped son. In our society, handicapped people are often labeled as inferior, abnormal and suffer several forms of prejudice, many of them based on misunderstanding reasons about their real capacities. The comprehension of the meaning attributed by parents upo
