1. Mudança na Política Externa dos Estados Latino-Americanos e Caribenhos: Uma Análise Baseada nas Votações da Assembleia Geral das Nações Unidas
RESUMO Neste artigo buscamos encontrar as principais condições conjunturais que podem aumentar as chances de Redirecionamentos na Política Externa (RPE), com base na análise de países latino-americanos entre 1945 e 2008. O objetivo é testar o efeito de variáveis identificadas com o conceito de “janela política”, utilizado pela literatura para def

2. Method to Determine the Root Canal Anatomic Dimension by using a New Cone-Beam Computed Tomography Software
Resumo Este estudo discute um método para determinar a dimensão anatômica do canal radicular usando o software e-Vol DX. A metodologia consiste em inicialmente estabelecer as posições corretas que serão medidas, definir o ponto na borda da estrutura anatômica e ajustar a posição intermediária na escala de cinza na imagem em tomografia computadoriza

3. Conjuntos minimais de pontos fixos e coincidências de aplicações fibradas / Conjuntos minimais de pontos fixos e coincidências de aplicações fibradas
Esta tese foi desenvolvida em duas partes. Inicialmente, consideramos um par de aplicações que preserva fibra, f1, f2 : M → M, em um fibrado com base S1 e fibra garrafa de Klein. Utilizando-se de um sistema algébrico de equações, descobrimos em que situações o conjunto minimal de coincidências sobre S1 do par (f1, f2) é vazio. Na segunda parte

4. Sobre teoremas de equilíbrio de Nash / On Nash equilibrium theorems
In this work, applying methods of Algebraic Topology, we obtain new versions of the Nash equilibrium theorem. We define a concept of local equilibrium for non-cooperative games, the socalled weak local equilibrium, and we prove its existence when the spaces of strategies are differentiable manifolds and the payoff functions are continuously differentiable.

5. THE DOCUMENTARY, THE TESTIMONIAL AND THE ROMANESQUE: ON HOW LUIZ ALBERTO MENDES CAME INTO BEING / O DOCUMENTAL, O TESTEMUNHAL E O ROMANESCO NA NARRATIVA AUTOBIOGRÁFICA: SOBRE COMO LUIZ ALBERTO MENDES VEIO A SER
By observing that the book Memórias de um sobrevivente by Luiz Alberto Mendes presents itself as an autobiography, but also passes through other genres, I propose to examine the documentary, the testimonial and the Romanesque aspects that compose this literary work. The coincidence between the names of the author, the narrator and the protagonist sets an au

6. "Implementação da técnica de correlações angulares perturbadas no laboratório Pelletron para estudo de estruturas e interações de biomoléculas" / Implementation of The Perturbed Angular Correlations Technique at The Pelletron Laboratory for the Study of Biomolecules Structures and Interactions
This work is related to the implementation of a perturbed angular correlation (PAC) spectrometer at the University of São Paulo Pelletron Laboratory. The spectrometer consists of 6 cylindrical BaF$_2$ scintillator detectors, with 3 inches diameter and 6 inches length and a multiparameter CAMAC data acquisition system. Different from usual, the gamma ray ene

7. Literature, fine arts and cinema: correspondences and transformations in Clarice Lispector / Literatura, artes plásticas e cinema: correspondências e transformações em Clarice Lispector
The expression ut pictura poesis by Horaces Ars Poetica gave rise to the inter-relationship of the signs of arts. Hence, if relationships can be established between poetry and painting, likewise, there are some possible relationships amongst the literary text and other arts and medias. This study hypothesizes that similar cosmovisions express similar transla

8. New gamma transitions in 193Ir from the beta decay of 193Os
The population and the mode of decay of the low-lying excited levels of 193Ir have been investigated by single and gg coincidence spectroscopy using 192Os enriched to 99% and several HPGe detectors. From singles spectra analysis the energies of 71 gamma rays have been determined with a better overall precision than previously, 17 of

9. Standardization of Ca-45 radioactive solution by tracing method
The procedure followed by the Laboratório de Metrologia Nuclear (LMN) at the IPEN, in São Paulo, for the standardization of the 45Ca is described. The activity measurement was carried out in a 4pb-gamma coincidence system, by the tracing method. The radionuclide chosen as the beta-gamma emitting tracer nuclide was 60Co because of i

10. Espectroscopia de multicoincidencia aplicada ao estudo de moleculas
The main purpose of this thesis is to study selective photo-fragmentation processes of free molecules excited by synchrotron radiation using multi-coincidence spectros-copy. Below are summarized some original and important contributions of this work: 1) We show for the first time experimental evidences of ultrafast dissociation in water molecule after O1s ®

11. The natural center of chromaticity space is not always achromatic: A new look at color induction
Although current theories of color vision differ in many respects, they all assume the existence of a uniquely defined neutral point in chromaticity space. It generally is assumed that this point satisfies several criteria simultaneously. One of these criteria is that it is perceived as achromatic. A further criterion shared by most theories is the structura

12. Checkpoint controls in Schizosaccharomyces pombe: rad1.
'Checkpoint' controls ensure that the events of the cell cycle are completed in an orderly fashion. For example, such controls delay mitosis until DNA synthesis and repair of radiation-induced DNA damage are complete. The rad series of radiosensitive fission yeast mutants was examined to identify strains deficient for the DNA damage-responsive checkpoint con
