A fundamentação teórica para esta investigação é a teoria do capital humano, que sustenta que o investimento privado em conhecimento por um indivíduo por meio da escolarização e da qualificação constitui-se em uma forma de capital capaz de elevar a produtividade e auferir benefícios econômico-financeiros. O propósito geral da pesquisa foi analisar o retorno e o impacto econômico proporcionado aos egressos dos cursos de Pós-Graduação stricto sensu em Administração, na modalidade de Mestrados Profissionais em Administração (MPA) ofertados pela Universidade de Brasília (UnB) até 2012. Foi construído e aplicado aos titulados pelo MPA-UnB um questionário com 15 perguntas fechadas, o qual foi respondido por 70,1% do total de egressos. Os parâmetros dos três modelos produzidos foram estimados pela regressão probit. Os resultados corroboram a expectativa de que a formação em nível de pós-graduação proporciona melhoria na vida dos indivíduos, traduzida em recompensas financeiras e em retornos positivos de outra natureza. ______________________________________________________________________________ ABSTRACT / This paper seeks to contribute with empirical evidence about the existence of benefits of training at post-graduate courses, based on the precepts of the Human Capital Theory, which support that investment in knowledge by an individual, through schooling and qualification, is in a form of capital, considering that increase your productivity, certain him the economic and financial benefits. Based on this theoretical grounding, the purpose of the research was to analyze the return and the economic impact provided to graduates of courses Postgraduate stricto sensu, in the modality of Professional Master in Administration (MPA), offered by the University of Brasilia (UnB) until 2012. For data collection, was constructed and applied to the MPA-UnB graduating students, from four classes, a questionnaire consisting of 15 closed questions, which were answered by 70.1% of the total graduates. The method used in the data analysis was the probit regression, estimating three models. The results confirm the expectation that the training at post-graduate generates improvements in the lives of individuals, translated into financial rewards and positive returns otherwise, as suggested by the literature of human capital.

Para tanto, seleciona-se três obras de arquitetura religiosa projetadas pelo arquiteto Oscar Niemeyer em Brasília, sendo elas: Capela Nossa Senhora da Alvorada (1957-1958), Capela Nossa Senhora de Fátima (1957-1958) e a Catedral Metropolitana Nossa Senhora Aparecida (1958-1989). Sob estes três espaços consagrados verifica-se a problemática da ocorrência de integração ou de síntese das artes. Objetivando sistematizar o estudo, em primeiro lugar, investigam-se as diferentes proposições de integração ou síntese das artes na primeira metade do século XX e a compreensão das mesmas no edifício-sede do MESP (Ministério da Educação e Saúde Pública). Em seguida, a partir do levantamento documental iconográfico e das entrevistas do arquiteto e dos artistas convocados, analisa-se a relação arte-arquitetura estabelecida nos edifícios em estudo. Concluindo, com base na análise e interpretação dos dados coletados, objetiva-se contribuir para o entendimento do papel da arte nos espaços arquitetônicos modernos brasileiros, em especial, nas obras em estudo. ________________________________________________________________________________ ABSTRACT / The research consists in the thematic approach relational between the visual arts and the modern Brazilian architecture. For both, it selects three works of religious architecture designed by architect Oscar Niemeyer in Brasilia, them being: Chapel of Our Lady of Alvorada (1956-1958), Chapel of Our Lady of Fatima (1857-1958) and the Metropolitan Cathedral Our Lady Aparecida (1958-1989). Under these three spaces enshrined there is the problem of the occurrence of integration or a synthesis of the arts. Aiming to systematize the study, in the first place, it investigates the different propositions of integration or synthesis of the arts in the first half of the 20th century and the understanding of same at the MESP (Ministry of Education and Public Health). Then, from the iconographic documentary survey and interviews of the architect and the artists summoned, it analyzes the relationship between art-architecture established in these buildings. In conclusion, based on the analysis and interpretation of the collected data, the objective is to contribute to the understanding of the role of art in modern Brazilian architectural spaces, in particular, in the works under study.

Asdministration; presents the situation of small scale grocers - their organizational structure, objectives and operational methods. This study has been divided into seven chapters. First, the author examines the dynamic aspects of the distribution flow where changes occur due to alteration of management objectives and strategies in the channel or interested agencies, as a mirror of environmental needs. From this standpoint , the significant éhanges which have ocurred in Brazil and the necessity of providing functional specialization for the people who make up the actual distribution system are viewed. It then covers the evolution and present day struc ture of the institution chich integrates the retail and whole sale business, the voluntary chain, as a consistent answer within its native land as well as other countries, in the search for efficiency and affectiveness in the distribution of products. Its offers explanation, at the same time, of the operational, political and organizational models. It presents the analysis of the small scalers in the towns surrounding Brasília, which reveals their lack of ony organization, qualified Iabour force or sufficient funds, and it pIaces stress on the voluntary chain as an aIternative solution to this faulty situation by means of adequate technological assistance. Adopting the system, it foresees the gradual eIimination of the dyadic supply Iines of the population which always favour the higher income bracket. FinaIly, the author estabiIishes normative, operitional and programmatic features consequent upon his anaIysis of the situation. / Este estudo procura descer aos pormenores da situação operacional para conhecer as causas que o levam a ser o que é; sua operação organizacional, diretrizes e métodos de operação. O foco do nosso trabalho é diretamente entre a periferia do centro urbano de Brasília, as Cidades Satélites, distantes de uns poucos a várias dezenas de quilômetros da mesma, surgidas da necessidade de abrigar a população vizinha à parte planejada, o plano piloto, como se chamou posteriormente.

This study evaluates the effectiveness of fiscal (and monetary) policies on a set of macroeconomic objectives, giving explicit consideration to the alternative modes by which the budget deficits (or surpluses) are financed. The extent to which quantitative reductions in the share of the public sector is compatible with these objectives is also examined. The evaluation of optimal macroeconomic policies is undertaken in the context of the Greek economy, since the financial aspects of the budget have not received the necessary attention. The method of analysis is carried out within an optimization framework which employes an econometric model of the Greek economy estimated over the period 1957-75, and a quadratic objective function depicting the desires of the policy-makers. The specific characteristics of the Greek economy necessary for the construction of the econometric model and the specification of the objective function are discussed in Chapter 2. Chapter 3 deals with the theoretical considerations of the macroeconomic model and presents the optimization approach persued in the study. Chapter 4 presents the econometric model and discusses its dynamic characteristics and structure. The specification of the objective function and the optimization results are discussed in Chapter 5. The major findings of the study are summarized in Chapter 6.

Ingeniera Civil Mecánica / El presente trabajo de título corresponde al análisis de la influencia de los términos de transporte de calor y momentum turbulentos, de las ecuaciones de Navier Stokes y del calor, en el confinamiento de una fuente de calor, que pudieran originar fugas de calor y gases en el uso de cortinas de aire con configuración Doble Jet Doble Flujo (DJ DF) como método de confinamiento al interior de túneles viales. Se estudiaron dos casos, considerando una cortina de aire DJ DF cuyo jet caliente está siempre en contacto con la zona confinada. Uno de ellos consiste en el uso del jet caliente con la mayor velocidad inicial de la configuración, y otro en que el jet frío posee la máxima velocidad inicial. Se realizó un estudio del campo, perfil y evolución en las zonas de capas de mezcla y línea central de la cortina, de los siguientes términos: esfuerzo de Reynolds, transportes axial y transversal de calor turbulentos, y sus derivadas parciales, las cuales evidencian su contribución en el incremento de flujo de momentum medio y de calor del flujo medio debido a fluctuaciones turbulentas. Dichos términos turbulentos fueron calculados con el método de diferencias finitas de orden O(h^4), utilizando datos numéricos extraídos de una simulación previa, que utilizó el modelo LES en ANSYS Fluent. Los esquemas forward , backward y central fueron aplicados en puntos extremos y central del dominio, respectivamente. Los resultados evidenciaron la existencia de un traspaso transversal de momentum y calor en niveles de la cortina de aire ubicados entre x/H=0.4 y 0.7, para ambos casos estudiados, siendo mayor en el del jet caliente más veloz. Esto, debido a peaks negativos en gráficos de evolución del transporte transversal de calor en capas de mezcla, que justificarían el intercambio de momentum y calor debido a fluctuaciones de las partículas fluidas. El rango de niveles mencionado coincide con la zona en donde ambos jets de la cortina se unifican para formar uno nuevo, con distintas características a los dos iniciales. La interacción entre ambos jets con distintas características termodinámicas disminuye la capacidad de confinamiento de la configuración propuesta. El análisis de transporte axial de calor muestra una inversión en el flujo de calor axial a partir de x/H=0.6 para el caso 1. Se concluye que la configuración que utiliza el jet frío de mayor velocidad inicial funciona un 60% mejor como barrera confinatoria respecto al caso del jet caliente más veloz. Se sugiere estudiar la influencia de los términos turbulentos en cortinas de aire inclinadas y analizar el paso de las partículas fluidas de manera de concluir sobre la naturaleza de los procesos de transporte de momentum responsables del esfuerzo de Reynolds.

In the field of orthopaedics and traumatology, a whole series of problems appear related to fracture fixation by means of various types of plates. Appropriate application of the plate is the difficult task that a doctor needs to deal with in the operating room. Regarding mechanics, the number of screws and their spacing have a major impact on the healing process. If there are too many screws or lack of them, the fracture does not heal properly. This can lead to implant failure. This work deals with stress-strain analysis of screws and bone tissue with a fracture fixed by LCP. It deals with the influence of different geometrical configurations of the screws on the stress, deformation and strain of the system. For this purpose, the computational modelling was used by means of the finite element method. Two computational models have been created, on which different screw arrangement was analysed. The first computational model represents diaphysis of the femur that is at the beginning of the healing process. For the four load models and eleven geometric configurations and number of the screws, a total of 44 computations were performed. The second computational model represents the distal part of the femur. Femoral geometry model was created based on CT (computed tomography) examination, geometric model of the plate was created by 3D scanning. Deformations and stresses were compared in the three geometric configurations of the screws during the healing process.

Para tanto, são utilizadas duas vertentes analíticas. A primeira, de caráter físico-espacial, trata dos aspectos configuracionais que determinam a sua espacialidade e possibilidades de apropriação social de seu espaço público. A segunda, de caráter gerencial, analisa o processo de gestão político-institucional que tem pautado o seu desenvolvimento urbanístico, enfocando os instrumentos jurídicos que respaldam esse trabalho – leis de proteção histórica e normas urbanísticas, bem como a postura técnica dos órgãos envolvidos. O propósito é o registro de ações, inquietações, contradições, intenções e desafios embutidos no modelo de gerenciamento urbano do espaço do Plano Piloto de Brasília, levantados a partir de uma leitura crítica da realidade urbanística dos espaços públicos e na cultura preservacionista que lhe tem dado sustentação. _______________________________________________________________________________ ABSTRACT / The study herewith presented runs through the urban reality of urban set of the Brasília Pilot Plan, seeking to reflect on its spatiality and the urbanistic management process in the light of historic preservation. In that sense, two analytical directives are used. The first, of physical/spatial nature, deals with urban design that determines both its spatiality and the possibilities of social appropriation. The second one, of managerial nature, analyses thepolitical/institutional management process that has distinguished the urbanistc development, by focusing on the juridical tools that support this work – laws of historic protection and urban planning rules, besides the technical background of the involved organisms. The purpose to be attained is the record of inquietudes, contradictions, actions, intents and challenges, all comprehended in the urban management model of space of the Brasilia Pilot Plan, brought about from the critical interpretation of urbanistc reality of public spaces and the preservationist culture that holds it up.

In dieser Arbeit wird die Signalanalyse eines Ortsdosisleistungsmessgerät mit organischem Szintillatoren der Arbeitsgruppe Strahlungsphysik optimiert, damit die Signalanalyse die Anforderungen der PTB im Hinblick auf eine Baumusterprüfung erfüllt. Dafür wird der Mittellungszeitraum der Dosisleistung dynamisch an die Zählrate angepasst, um einen Kompromiss zwischen schneller Ansprechzeit und geringer statistischer Messunsicherheit der gemessenen Dosisleistungen zu erreichen. Bei hohen Zählraten wird die Datenmenge begrenzt, damit die CPU nicht mit der Auswertung der Einzelereignisse überlastet wird. Weiterhin wird für 2 Prototypen des Dosimeters eine Energiekalibrierung und Wichtung gefunden. Als zusätzliches Feature ist eine Fourier-Transformation implementiert, mit der die Frequenz von gepulster Strahlung bestimmt wird.:Inhaltsverzeichnis 1 Motivation 1 2 Physikalischer Hintergrund 3 2.1 Dosis 3 2.2 Kernreaktionen 3 2.3 Wechselwirkung zwischen Strahlung und Materie 4 2.4 Detektoren 6 3 Material und Methoden 9 3.1 Aufbau und Funktionsweise 9 3.2 Funktionsprüfung 13 3.3 Kalibrierung 15 3.4 Anforderungen der PTB 18 3.5 Überlastungsschutz 19 3.6 Fourier-Transformation 20 4 Messungen 23 4.1 Messung mit dem Pulsgenerator 23 4.2 Messungen mit dem NaI-Szintillator 25 4.3 Messungen mit organischem Szintillator 27 5 Zusammenfassung 41 6 Anhang 43 6.1 Beobachtete Röntgen und γ-Linien 43 6.2 Pulsladungshistogramme 44 Abbildungsverzeichnis 53 Tabellenverzeichnis 55 Literatur 57 / In this thesis, the signal analysis of a local dose rate measurement device is improved for a type examination at the PTB. For this the averaging time of the dose rate measurement is dynamically optimized to archive a trade-off between a short reaction time and low statistical uncertainty of the measured dose rate in order to fulfil the expectations of the PTB and an overload protection is added to ensure a swift analysis of the incoming events even at high count rates. Furthermore, an energy calibration and weight is determined for two prototypes of the dose rate measurement device. As an additional feature a Fourier transformation is implemented to determine the frequency of pulsed radiation fields.:Inhaltsverzeichnis 1 Motivation 1 2 Physikalischer Hintergrund 3 2.1 Dosis 3 2.2 Kernreaktionen 3 2.3 Wechselwirkung zwischen Strahlung und Materie 4 2.4 Detektoren 6 3 Material und Methoden 9 3.1 Aufbau und Funktionsweise 9 3.2 Funktionsprüfung 13 3.3 Kalibrierung 15 3.4 Anforderungen der PTB 18 3.5 Überlastungsschutz 19 3.6 Fourier-Transformation 20 4 Messungen 23 4.1 Messung mit dem Pulsgenerator 23 4.2 Messungen mit dem NaI-Szintillator 25 4.3 Messungen mit organischem Szintillator 27 5 Zusammenfassung 41 6 Anhang 43 6.1 Beobachtete Röntgen und γ-Linien 43 6.2 Pulsladungshistogramme 44 Abbildungsverzeichnis 53 Tabellenverzeichnis 55 Literatur 57

Les satellites en orbite terrestre se déplacent dans le plasma ionosphérique, un mélange de particules chargées, et éventuellement de particules neutres. Des électrons et des ions issus de ce plasma, ainsi que les émissions Ultra-Violets(UV) en provenance du soleil, interagissent avec les surfaces du satellite et modifient sa charge électrostatique. Cette chargement peut induire elle-même des décharges électrostatiques aux conséquences allant de perturbations électromagnétiques (fausses commandes par exemple) à la perte du satellite. En orbites de basse altitude (LEO) l'énergie cinétique et thermique du plasma est généralement faible et donc, les satellites vont rarement présenter des décharges importantes. Néanmoins, les missions scientifiques qui embarquent des instruments très performants et précis peuvent être affectées par cette interaction satellite-plasma-émissions UV. Cette thèse s'intéresse particulièrement à ces phénomènes de charge des structures externes du satellite et à l'impact de ce chargement sur les mesures scientifiques effectuées à bord, i.e. mesures du champ électrique et de la densité du plasma thermique. / Earth-orbiting satellites travel in ionospheric plasma, a mixture of charged particles, and possibly neutral particles. Electrons and ions from this plasma, as well as Ultra-Violet (UV) emissions from the sun, interact with the surfaces of the satellite and modify its electrostatic charge. This loading can itself induce electrostatic discharges to the consequences ranging from electromagnetic disturbances (false commands for example) to the loss of the satellite. In low-Earth orbits (LEO), the kinetic and thermal energy of the plasma is generally low and therefore satellites rarely exhibit large discharges. Nevertheless, scientific missions that carry high-performance and accurate instruments can be affected by this satellite-plasma-UV-emissions interaction. This thesis is particularly interested in these phenomena of charge of the external structures of the satellite and the impact of this load on the scientific measurements carried out on board, i.e. measures of the electric field and the density of the thermal plasma.

Para tal, três momentos foram considerados: o que foi imaginado; a obra construída e inaugurada em 1960; e a obra modificada ao longo dos anos. Buscou-se ainda, através de uma pesquisa sobre as praças ao longo da História, compreender as referências do ponto de vista plástico-espacial utilizadas para a praça dos Três Poderes, tanto na idéia pretendida como no que foi interpretado. Utilizando-se um tratamento qualitativo de medidas, as situações consideradas foram comparadas no que diz respeito, principalmente aos aspectos morfológicos. A praça construída e inaugurada em 1960 respeita de forma considerável as características morfológicas identificadas na idéia imaginada. As modificações realizadas acabaram por desvirtuá-las de forma irremediável. _______________________________________________________________________________ ABSTRACT / The main goal of this dissertation is to understand the idea planned by Lucio Costa for the Square of The Three Powers for the project of Pilot Plan in Brasília. In order to do so, three steps were taken into account: what it was imagined, the construction itself inaugurated in 1960 and its modification carried out throughout the years. By the means of a historical research on squares, this paper tries to understand the point of view of plastic-spacial references used for the Square of the Three Powers, in its intended and interpreted idea. Using a qualitative treatment of measures, the considered situations have been compared mainly in its morphological aspects. The square constructed and inaugurated in 1960 respects, in a considerable way, the morphological aspects identified in the imagined idea. The further modifications resulted in irreparable changes in the original project.
