Les métamatériaux à indice de réfraction négative ont attiré énormément l'attention ces dernières années surtout à cause de leurs propriétés électromagnétiques uniques. Ces matériaux sont des structures artificielles qui présentent des caractéristiques n'étant pas disponibles en matériaux naturels. Récemment, le développement technologique avec de nouvelles techniques de fabrication offrent un grand nombre de nouvelles application et développement de nouveaux matériaux. Il est possible d'obtenir un métamatériau en combinant des structures artificielles périodiquement. Les propriétés uniques du Split Ring Resonator (SRR), les Surfaces à Haute Impédance (HIS), les Surface Sélective en Fréquence (FSS) sont étudiées ainsi que les métamatériaux composés. Il a été démontré avec succès l'utilisation pratique de ces structures dans les circuits et les antennes. Il a été confirmé expérimentalement que les métamatériaux pourrait améliorer la performance des structures considérées dans cette thèse, pour des fréquences où la bande interdite électromagnétique se produit.

Tip60 is a 60 kDa nuclear protein which exists in three isoforms, belongs to the MYST/HAT family of proteins and was discovered after its interaction with the Human HIV-1 Tat. As a nuclear protein, Tip60 can act as a coactivator or repressor. To understand the HAT action of Tip60, two possible catalytic models exist; the ping-pong and the ternary complex formation models. In correlation with the exploration of HAT catalytic action, mutations of a Cys to Ala and a Glu to Gln on Esa1 (yeast homolog of Tip60 and MYST/HAT prototype), was reported to show wild type-like and decreased acetylating properties, respectively. In this work, Tip60 HAT action was explored. In Tip60, the Cys in the active site is important for acetylation of the H4(1-20) substrate and the Glu showed semi loss in acetylating the H4(1-20) peptide substrate. These data highlight a unique mechanism of Tip60 catalysis.

Hydrologic Information Systems (HIS) have emerged as a means to organize, share, and synthesize water data. This work extends current HIS capabilities by providing additional capacity and flexibility for marine physical and chemical observations data and for freshwater and marine biological observations data. These goals are accomplished in two broad and disparate case studies – an HIS implementation for the oceanographic domain as applied to the offshore environment of the Chukchi Sea, a region of the Alaskan Arctic, and a separate HIS implementation for the aquatic biology and environmental flows domains as applied to Texas rivers. These case studies led to the development of a new four-dimensional data cube to accommodate biological observations data with axes of space, time, species, and trait, a new data model for biological observations, an expanded ontology and data dictionary for biological taxa and traits, and an expanded chain-of-custody approach for improved data source tracking. A large number of small studies across a wide range of disciplines comprise the “Long Tail” of science. This work builds upon the successes of the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) by applying HIS technologies to two new Long Tail disciplines: aquatic biology and oceanography. In this regard this research improves our understanding of how to deal with collections of biological data stored alongside sensor-based physical data. Based on the results of these case studies, a common framework for water information management for terrestrial and marine systems has emerged which consists of Hydrologic Information Systems for observations data, Geographic Information Systems for geographic data, and Digital Libraries for documents and other digital assets. It is envisioned that the next generation of HIS will be comprised of these three components and will thus actually be a Water Information System of Systems. / text

The purpose of this study was to investigate the place and role of tradition in the Nigerian novel. For many years, in my attempt to find out some of the causes of the difficulties our countries are facing, I have come to suspect our traditions as being one major cause. In fact, this study has shown that our traditions, though supposedly destroyed by colonization, have retained many of their aspects which are cunningly at work in our societies, together with European traditions.Because the essential role of tradition is to define the present, we need to find out more about our traditions in order to know how we can best explore them for the advancement of our countries in a changing world.

Foreign king Cyrus, in the text of Is 45,1-7 is intitled of Messiahs de Javé. Therefore, this research has as objective to reflect on the messianic heading attribution to king Cyrus, in the context of the Babylonian exile. For this, I analyze some contributions of diverse authors and authors of the Biblical area, exploring the diversity of analyses on this subject. It has many interpretations on the meaning of the messianic heading attributed to the king Cyrus, between them, it has who defines Cyrus as the Messiahs de Javé, that is, Cyrus as liberating of the exiled ones and not as the substitute of the messianic hope in a Messiahs proceeding from the house of David. In this work, I still argue has messianic hope, manifest in the exilic period and after-exilic, detaching the faith that the messianic communities exerted in these periods. At last, I analyze the messianic of the neo-testamentary communities after-macabaicas and in the attempt discovering if Cyrus was one messianic figure, in these periods. / O livro do profeta Dêutero-Isaías aborda que Javé vem consolar seu povo exilado na Babilônia. O rei estrangeiro Ciro, no texto de Is 45,1-7 é intitulado de Messias de Javé. Portanto, esta pesquisa tem como objetivo refletir sobre o título messiânico atribuído ao rei Ciro, no contexto do exílio babilônico. Para isto, analiso algumas contribuições de diversos autores e autoras da área bíblica, explorando a diversidade de pesquisas sobre este tema. Há muitas interpretações sobre o significado do título messiânico atribuído ao rei Ciro, entre elas, há quem define Ciro como o Messias de Javé, ou seja, Ciro como libertador dos exilados e não como o substituto da esperança messiânica em um Messias proveniente da casa de Davi. Neste trabalho, discuto ainda a esperança messiânica, manifesta no período exílico e pós-exílico, destacando a fé que as comunidades messiânicas exerciam nestes períodos. Enfim, analiso o messianismo das comunidades pós-macabaicas e neo-testamentárias na tentativa de descobrir se Ciro era uma figura messiânica, nestes períodos.

This thesis explores representations of wild nature in two Arthurian texts – one British and one American – produced in an age characterised by rapid social transformation: Alfred, Lord Tennyson’s Idylls of the King (1859-1885) and Howard Pyle’s Story of King Arthur and His Knights (1903). By investigation of the textual descriptions of wilderness and the portrayals of characters living there, the study aims to investigate what attitudes towards unkempt nature are displayed in the two texts. While both narratives give evidence of a powerful nostalgia for a vanishing paradise, the yearning for Eden is expressed quite differently. Pyle’s text fuses the concepts of wilderness and paradise together by depicting the unkempt landscape as a place of splendour and spiritual enjoyment. Such a celebration of nature might well be seen a reaction against the rapid loss of wild spaces across America (and Britain) during the life-time of the author. In the Idylls, paradise is represented in the domesticated yet green landscape of the faraway fairy island of Avilion. Wilderness, on the other hand, is depicted as a harmful disease progressively spreading across the realm, arguably bringing about a moral degeneration among the human characters. In the end, however, it is not wilderness, but the corruption of the supposedly civilised characters that causes the collapse of Arthur’s empire. On closer inspection, the real danger thus seems to come from culture and material conditions rather than from nature.

These services generate costs, which are the maintenance costs. And when you speak of the study of maintenance costs in Social Housing, this is a little explored subject, and when it comes to the ones which were built with some innovative/ unconventional building system even more. From the knowledge of this gap in terms of maintenance costs on Social Housing and starting from this scenario this dissertation addresses the issue of maintenance costs in Social Housing that used the innovative building system of "sealing walls in molded concrete slabs on site" from the district Mariz I, located in João Pessoa-PB. For the elaboration of the aforementioned dissertation the approach method was deductive, we used the techniques of direct and indirect documentation (extensive) and was adopted probabilistic sampling process. The research that was carried out and has as product this dissertation is classified as to nature, in quantitative, as the purpose in applied, as the type, descriptive and on the design, in survey research. This work proposes to detail all the items that have undergone maintenance over the years studied in the Social Housing addressed, as well as costs arising from this activity, called actual costs; seeking in prior, with the known values of maintenance expenditures, to project itself in terms of future costs for a given period in each case, from the development of a measurement tool for the maintenance costs that uses the principle of cost-significant item (CSI) and aided by statistical mechanisms. However, as the work progressed other relevant factors were becoming notorious, such as the influence of socioeconomic status of the buildings residents with maintenance costs; the calculation of the cost items that were not done maintenance work, but it was found the need to be made, those called potential costs; the perception of the buildings conservation status in the optics of quality of maintenance practice, among others. In general it was found that the maintenance of the activity was carried out informally and in corrective manner. It has been seen that 22% of maintenance items contributed to 95% of the actual costs of the analyzed buildings. The paint item was the most representative, in terms of effective maintenance costs. About the potential costs, in the most of dwellings, there was a tendency of proportional reversal of the amount thereof compared to actual costs. The values of the maintenance costs were directly proportional to the purchasing power of residents, income limitations of these influenced the absence / postponement of the building’s maintenance, and also in the final result of their execution. / As edificações sofrem degradação com o tempo, necessitando, portanto, da realização de serviços de manutenção. Esses serviços geram despesas, que são os custos de manutenção. E quando se fale do estudo dos custos de manutenção em HIS, este é um assunto pouco explorado, e se tratando das que foram construídas com algum sistema construtivo inovador/não convencional ainda mais. A partir do conhecimento desta lacuna em termos de custos de manutenção em HIS e partindo desse panorama a presente dissertação aborda a questão dos custos de manutenção em HIS que utilizaram o sistema construtivo inovador de “paredes de vedação em placas de concreto moldadas in loco” do conjunto Mariz I, localizado na cidade de João Pessoa- PB. Para a construção da supracitada dissertação o método de abordagem utilizado foi o dedutivo, foram utilizadas as técnicas de documentação indireta e direta (extensiva) e foi adotado o processo de amostragem probabilista. A pesquisa que foi realizada e tem como produto esta dissertação, classifica-se quanto à natureza, em quantitativa, quanto à finalidade em aplicada, quanto ao tipo em descritiva e quanto ao delineamento, em pesquisa de levantamento. Este trabalho se propôs a detalhar todos os itens que sofreram manutenção ao longo dos anos estudados nas HIS abordadas, bem como os custos oriundos desta atividade, denominados de custos efetivos; buscando a priori com os valores conhecidos dos gastos com manutenção se projetar apenas em termos de custos futuros para um dado período em cada caso específico, a partir do desenvolvimento de uma ferramenta de mensuração de custo de manutenção que utiliza-se do princípio de itens custos significativos (CSI) e auxiliada por mecanismos estatísticos. No entanto, à medida que se deu o andamento do trabalho outros fatores relevantes foram se tornando notórios, tais como: a influência da situação socioeconômica dos moradores das edificações com os custos de manutenção; o cálculo dos custos de itens em que não foram feitas intervenções de manutenção, mas que se constatou a necessidade de serem feitas, estes denominados de custos potenciais; a percepção do estado de conservação das edificações na ótica da qualidade da prática da manutenção, entre outros aspectos. Em linhas gerais constatou-se que a atividade de manutenção, foi realizada informalmente e de maneira corretiva. Foi visto que 22% dos itens de manutenção contribuíram com 95% dos custos efetivos das edificações analisadas. O item pintura foi o mais representativo, em termos de custos efetivos de manutenção. Sobre os custos potenciais, na maioria das moradias, há uma tendência de inversão proporcional do montante destes, em relação aos custos efetivos. Os valores dos custos de manutenção foram diretamente proporcionais ao poder aquisitivo dos moradores, as limitações de renda destes influenciaram na ausência/protelação da manutenção das edificações, mas também no resultado final da sua execução.

O presente trabalho tem como objetivo analisar o impacto da utilização instrumento das Operações Urbanas, como forma alternativa para captação de recursos pelo poder público através da atividade do setor imobiliário para implementar melhorias sociais e ambientais na cidade de São Paulo, em especial no que se refere a provisão habitacional às famílias diretamente atingidas pela Operação Urbana, através do estudo de caso da Operação Urbana Água Espraiada no período de 2001 a 2015. O trabalho pretende estudar elementos determinantes para a formação instrumento Operações Urbanas Consorciadas, até sua consolidação como instrumento de política nacional de desenvolvimento urbano no Estatuto da Cidade e quais os impactos gerados na cidade a partir de sua aplicação, com foco na implantação de habitação de interesse social. Para tanto, fazemos um pequeno histórico sobre a aplicação deste instrumento na cidade de São Paulo, enfocando especialmente a Operação Urbana Água Espraiada, destacando os principais momentos que marcaram sua trajetória, buscando explicitar os resultados alcançados pela provisão habitacional desta operação. Tais resultados são analisados em termos de eficiência na utilização de verbas públicas, eficácia no alcance das metas e cumprimento de prazos e efetividade da política pública no enfrentamento do problema habitacional. Apesar da alta qualidade arquitetônica dos poucos edifícios produzidos, os resultados apontam para um efeito pouco expressivo sobre o problema habitacional às margens do córrego Águas Espraiadas, que ao invés de diminuir, acabou aumentando ao longo do período de vigência da operação, além de remeter a necessidade de priorizar a aplicação dos recursos em obras que atendam o interesse público e de criação de mecanismos que garantam a permanência da população de baixa renda frente à valorização imobiliária da região. / The present study aims to analyze the impact of the implementation of the Urban Operation Consortium, as an alternative of fundraising by the Government through the construction sector activity to implement social and environmental improvements in São Paulo, particularly the effectiveness of housing provision to the families directly affected by the Urban Operation, through the case study of the Água Espraiada Urban Operation Consortium in the period between 2001-2015. The work intends to study the main elements of the Urban Operation Consortium, until its consolidation as an instrument of national policy of urban development in the City´s Statute, and what were the impacts generated in the city by its implementation, focusing on the construction of social housing. Having that in mind, we intend to recover some of the history of the application of this instrument in the city of São Paulo, focusing especially on the Água Espraiada Urban Operation highlighting its key moments, and the achievements of the social housing provision. These results were analyzed in terms of efficiency in the use of public funds, effectiveness in achieving the goals in time and effectiveness of public policy in facing the housing problem presented. Despite the high architectural quality of the buildings produced, the results point to a very little significant effect in solving the housing problem on the banks of the Água Espraiada stream, which actually increased instead of decreasing, throughout the duration of the urban operation. In addition, the results refer to the need to prioritize the application of resources in investments that attend to the public interest and to the creation of mechanisms to ensure the permanence of the low- income population against the real estate valuation in the region.
