13. Thermal effects on the stability of circular graphene sheets via nonlocal continuum mechanics
Recently, graphene sheets have shown significant potential for environmental engineering applications such as wastewater treatment. Different non-classical theories have been used for modeling of such nano-sized systems to take account of the effect of small length scale. Among all size-dependent theories, the nonlocal elasticity theory has been commonly use

14. Desenvolvimento de um simulador para espectrometria por fluorescência de raios X usando computação distribuída / Development of a X-ray fluorescence spectrometry simulator using distributed computing
Radiation Physics is a branch of Physics that is present in various studying areas and relates to the concept of spectrometry. Among the numerous existing spectrometry techniques, there is the X-ray fluorescence spectrometry. It also has a range of variations which can emphasize a particular subset of techniques. The production of X-ray fluorescence enables

15. Application of an iterative method and an evolutionary algorithm in fuzzy optimization
This work develops two approaches based on the fuzzy set theory to solve a class of fuzzy mathematical optimization problems with uncertainties in the objective function and in the set of constraints. The first approach is an adaptation of an iterative method that obtains cut levels and later maximizes the membership function of fuzzy decision making using t

16. Demonstrações bijetivas em partições / Bijectives demonstrations in partitions
This work presents some results about partitions of integers numbers and their importance in the history of Mathematics and in the Theory of the Numbers. To find bijective demonstrations in partitions it is not easy. But, after finding them, to understand and to prove some Identities of Partitions becomes agreeable and easy. This work intends to be didatic a

17. Decaimentos de mésons D e DSJ no modelo C3P0
The Fock-Tani representation is a field theory formalism appropriated for the simultaneous treatment of composite particles and their constituents. The 3P0 model is a typical decay model which considers only OZI-allowed strong decays. The model considers a quark-antiquark pair created with the vacuum quantum numbers in the presence of the initial state meson

18. Essays on decision sciences: exploring cognition, information processing, and complexity
This thesis provides three original contributions to the field of Decision Sciences. The first contribution explores the field of heuristics and biases. New variations of the Cognitive Reflection Test (CRT--a test to measure "the ability or disposition to resist reporting the response that first comes to mind"), are provided. The original CRT (S. Frederick [

19. RepresentaÃÃes sociais de homens e mulheres de Coari sobre qualidade de vida / social representation of men and women of coari in quality of life
The term quality of life has been widely used in the discourse of professionals and health managers. In Brazil, although the health reform movement and the various attempts to improve primary health care, there is still a gap between theory and practice. Key aspects such as the recognition of personal autonomy and empowerment, which enables the change of att

20. Adrien-Marie Legendre (1752-1833) e suas obras em Teoria dos Números
The present thesis is an analysis of Adrien-Marie Legendres works on Number Theory, with a certain emphasis on his 1830 edition of Theory of Numbers. The role played by these works in their historical context and their influence on the development of Number Theory was investigated. A biographic study of Legendre (1752-1833) was undertaken, in which both his

21. Preconditioners for higher order finite element discretizations of H(div)-elliptic problem
In this paper, we are concerned with the fast solvers for higher order finite element discretizations of H(div)-elliptic problem. We present the preconditioners for the first family and second family of higher order divergence conforming element equations, respectively. By combining the stable decompositions of two kinds of finite element spaces with the abs

22. Concepções de divisibilidade de alunos do 1 ano do ensino médio sob o ponto de vista da Teoria Apos
Este trabalho tem como objetivo investigar quais as concepções dos alunos de um primeiro ano do ensino médio sobre o conceito de divisibilidade dos números naturais. A relevância deste estudo está na importância que, segundo Campbell e Zazkis (1996) e Resende (2007), tem os conceitos pertinentes a divisibilidade no desenvolvimento do pensamento matem�

24. A categoria computável dos espaços coerentes gerados por conjuntos básicos com aplicação em análise real / The computable category of the coherence spaces generated by basic sets with an application in real analysis
Neste trabalho desenvolve-se um estudo sobre os Espaços Coerentes Gerados por Conjuntos Básicos, dotados de uma estrutura adicional. Por estrutura adicional entende-se uma estrutura algébrica, de ordem pontual, de medidas, topológica e lógica. Estes espaços, denotados por , constituem uma subcategoria dos Espaços Coerentes, cujos objetos, ordenados pe
