1. Exploratory and confirmatory factorial analysis of the OHIP-Edent instrument
Abstract Several instruments have been used to measure oral health-related quality of life (OHRQoL). The Oral Health Impact Profile (OHIP) questionnaire was based on the concept that sequential events related to oral diseases can cause discomfort, functional limitations and consequently, result in dysfunctions and even disabilities. There are few studies in

2. Generalized linear differential equations in a Banach space: continuous dependence on parameters and applications / Equações diferenciais generalizadas lineares em espaços de Banach: dependência contínua com relação a parâmetros e aplicações
The purpose of this work is to investigate continuous dependence on parameters for generalized linear differential equations in a Banach space- valued setting. More precisely, we establish a theorem inspired by the clas- sical continuous dependence result due to Z. Opial. In addition, our second outcome extends, to Banach spaces, the result proved by M. Asho

3. Sobre rigidez de hipersuperfÃcies completas / On rigidity of complete hypersurfaces
The purpose of this thesis is to obtain characterization theorems of complete spacelike hypersurfaces isometrically immersed in a semi-Riemannian ambient space under some restrictions on the Gauss mapping or about the r-mean curvatures of these objects. We start our work by providing necessary conditions to ensure the umbilicity of immersed hypersurfaces in

4. Identification and the information matrix : how to get just sufficiently rich?
In prediction error identification, the information matrix plays a central role. Specifically, when the system is in the model set, the covariance matrix of the parameter estimates converges asymptotically, up to a scaling factor, to the inverse of the information matrix. The existence of a finite covariance matrix thus depends on the positive definiteness o

5. Nonlinear turbulent transonic flow phenomena influence on aeroelastic stability analysis.
The present work is aimed at studying the influence of viscous effects in transonic aeroelastic analyses. To achieve this goal, a two-dimensional and viscous aeroelastic computational solver, for CAE analysis, is developed, which uses unstructured computational meshes and which is able to capture the main aeroelastic phenomena relevant in the transonic regim

7. The rates in complete moment convergence for negatively associated sequences
Let X1, X2,... be a strictly stationary and negatively associated sequence of random variables with mean zero and positive, finite variance, set Sn = X1+ ... + Xn, Mn = max1 < k < n |Sk|. Under appropriate moment conditions, we obtain precise rates in law of the logarithm for the moment convergence of Sn and Mn.

9. Estruturas de dados eficientes para algoritmos evolutivos aplicados a projeto de redes / Efficient Data Structures to Evolutionary Algorithms Applied to Network Design Problems.
Network design problems (NDPs) are very important since they involve several applications from areas of Engineering and Sciences. In order to solve the limitations of traditional algorithms for NDPs that involve real world complex networks (in general, modeled by large-scale complete or sparse graphs), heuristics, such as evolutionary algorithms (EAs), have

10. Contabilidade governamental brasileira no contexto da convergência aos padrões internacionais
With the globalization of the economy and the growing participation of several world investors in financial markets, combining the political, economical and social differences of each country, the varying Accounting Statements based on principles, standards, procedures or idiosyncratic accounting patterns become inadequate to provide comprehensible and usefu

11. A family of vortex rings and a variational application to potential flows around three-dimensional bodies
A variational formulation and solution of general three-dimensional potential flows gave rise to the construction of a special family of ‘trial functions’. This family is composed by circular-sector vortex rings, here named α-rings, i.e., rings that are positioned on the border of a circular sector with aperture angle α. An explicit formula for the vel

12. Correlation between margin fit and microleakage in complete crowns cemented with three luting agents
Microleakage can be related to margin misfit. Also, traditional microleakage techniques are time-consuming. This study evaluated the existence of correlation between in vitro margin fit and a new microleakage technique for complete crowns cemented with 3 different luting agents. Thirty human premolars were prepared for full-coverage crowns with a convergence
