This inter-disciplinary examination assesses the European ceramics in the collections of the Dukes of Hamilton over a number of generations. The study is based principally on the evidence found in the Hamilton and other archives, comprising both textual and visual sources. The second element that forms the foundation for the research is the connoisseurship of ceramics, both extant and those known only through documents. Evidence has revealed that the Duchesses of Hamilton play a major role in this work. A significant number of Hamilton ceramics have been newly identified and located, while their attribution, acquisition and history within the collections have been assessed and clarified.

In the twentieth century, collecting became a core activity of local authority art galleries and museums in Britain. A key feature of these art collections was the representation of Twentieth Century British Art. The aim of this study is to examine, for the first time, this development as abroad cultural phenomenon, through the distinctive roles played by central government-funded, and independent national and provincial art collection schemes. The central government-funded art collection schemes are the V. & A Purchase Grant Fund, War Artists' Advisory Committee and the National Heritage Memorial Fund; and the national loan and exhibition schemes offered by the Tate Gallery and the Arts Council. Independent schemes are more numerous and varied. These were administered by the National Art Collections Fund (now the Art Fund), Contemporary Art Society, Scottish Modem Arts Association, Contemporary Art Society for Wales, Henry Moore Foundation and Gulbenkian Foundation. In addition, there were the independent national loan and exhibition schemes offered by the Museums Association, Peter Stuyvesant Foundation and Alistair McAlpine and provincial schemes based in Manchester (Charles Rutherston Loan Scheme), Cardiff (National Museum of Wales Loan Scheme), Liverpool ('John Moores' competition-exhibitions) and Bradford ('International Print Biennale' competition-exhibitions). Given the geographical coverage, historical scope and focus of this study, a substantial body of published and unpublished literature was consulted. The wide-range of sources examined included institutional histories, biographies and studies of Twentieth-Century British Art; permanent collection and exhibition catalogues; newspaper, journal and magazine articles, curatorial records and correspondence; institutional records and correspondence; archival material and reports; and . correspondence and interviews. This entailed the discovery of much new material and the collation of substantial random data held by the Contemporary Art Society and the Gulbenkian Foundation This research seeks to show that local authority collecting of Twentieth-Century British Art was part of a nation-wide cultural pattern determined by certain ideas, theories and policies. Within this context, Section 1 identifies and discusses the nature and purpose of public art galleries, muscums and their art collections from 1845-1945. This momentous period in the museum movement in Britain, it is argued, sustained and generated ideas, theories and policies which encompassed national institutional hierarchies and their models of collecting, high art aesthetic standards and scholarship linked connoisseurship; the organic structure of museums; and multifaceted education. It concludes that during this formative period, an enduring cultural framework was established, from which emerged key collecting impetuses which are art history, patronage and heritage. Sections 2 and 3 examine the roles played by central government-funded and independent schemes, as a response to these issues, which also engendered and reinforced the collecting of specific types of Twentieth Century British Art. Section'4 surveys the local authority collections, which participated in the schemes, and concludes that 1957-79 was a crucial period in post-war collecting, which was both facilitated by the emergence of a considerable and dynamic network of commercial art galleries, and enhanced by national and provincial measures to decentralize the arts. A principal conclusion is that the future of modem (twentieth-century) and contemporary (twenty-first- century) British art collecting, by local authority art galleries and museums, lies in its perception as part of a collective cultural enterprise, in which the intervention of collection schemes will, as in the past, play a fundamental role. Finally, there is also a strong argument for provincial institutions to feed into a national debate as to what is selected to represent both modem and contemporary British art practice in public collections in general.

tA/v\Am (the Audio/Video Analysis Machine) is an interactive analysis engine optimized for audio/visual mediums, such as film, video games, and music. I designed tA/v\Am to allow users to pace the playback speed of videos containing sub-title style analytical text, without affecting the pitch content of the audio. The software affords writers the opportunity to display the relevant sensory data (i.e., analytical text and sound/visual media) more efficiently than the paper format. It also serves as a flexible medium; the writer may, for example, compress extensive text into a short amount of time, causing the reader to pause or slow down the rate of the video and thus suspending him/her in the sensorial moment which the writer describes. G®¡ND for Alto Saxophone, Percussion & Electronics is an exploration of the tipping point between signal and noise. Through tablature notation, MIR tools, granular synthesis, and the deconstruction of the saxophone, I have assembled a palette of inordinately contrasting sounds and threaded them together based on action profiles obtained by computer assisted analysis. With them, I have set varying physical conditions of friction that dictates whether the sonic energy is to become focused to one resonant point, or distributed equally/randomly throughout the spectrum as noise. In my critical essay, I use the software to analyze independent video games, showing how tA/v\Am is a highly appropriate tool for such analysis as it is an analogous medium. I then show the software's capabilities as a multimedia platform in analyzing acoustic music, as well as my own electroacoustic work, G®¡ND. In doing so, I advocate for a media-driven analyses, and maintain that one can communicate nuanced ideas using minimal verbal/textual explanation.

Thesis (M.S.)--Boston University

This study uses Additive Manufacturing (AM) processes to fabricate 316L stainless steel beams with pockets of unfused powder for increased damping. Modal testing was completed to compare damping factors of beams with varying pocket geometries as well as number of pockets and pocket location. For the first three bending modes that were tested, an initial damping increase was observed when pocket height is greater than powder diameter. Following the initial increase there is a height threshold, which is mode dependent, that is required to achieve a statistically significant increase in damping.

A pesquisa contou com três procedimentos de coleta de dados: análise documental, entrevistas e questionários, refletidos segundo a orientação metódica da Hermenêutica Crítica no diálogo com a teoria da enunciação de M. Bakhtin. Os estudos da Didática das Ciências compõem a maior parte do referencial teórico consultado. Assume o conceito de noosfera de Chevallard (2009) para refletir as múltiplas forças (explícitas e implícitas) que fazem corpo na elaboração e mediação das orientações sobre o ensino de ciências nos anos iniciais, e, por esse caráter, incidem na maneira pela qual os professores constroem suas concepções sobre a prática. O estudo evidenciou que aos professores é negada a oportunidade da compreensão, tal como o conceito é definido pela hermenêutica, como finalidade ultima do ato interpretativo... / Abstract: The present work is linked to the research line "Formative processes, teaching and learning" developed at the Postgraduate Program in Education in the Faculty of Science and Technology (UNESP), Presidente Prudente, discusses the role of guidance on the science teaching in the development of teachers conceptions, with the main objective: to investigate the interpretation of teachers about the guidelines on the science teaching in schools, through the way they understand the process and develop it in their training practice. The research involved three data collection procedures: analysis of documents, interviews and questionnaires, reflected according to the methodical guidance of Critical Hermeneutics in dialogue with the theory of enunciation of M. Bakhtin. Studies of Science Education compose most of the consulted theoretical framework. The research takes the concept of the noosphere of Chevallard (2009) to reflect the multiple forces (explicit and implicit) that make part of the development and mediation of guidelines on the science teaching in the early years, and for this character, focus on the way in which teachers build their conceptions of the practice. The research evidenced that the opportunity of understanding ise denied to the teachers, as the concept is defined by hermeneutics, as purpose of the interpretive act. This lack of understanding is due, among other factors, to the authoritarian and dogmatic character of the guidelines present both in documentary form and in the mediation style that derives from it. Such state of lack of dialogue prevents the construction of replicas and common senses, and this process is explained in the last part of the work in which the broader political and economic sphere plays an important role in the discussion of the data / Mestre

Resumo: Este trabalho teve como objetivo caracterizar diferentes solos da Bacia do Rio Negro-AM e mais especificamente a região do Rio Aracá-AM e estimar a contribuição deste para o ciclo biogeoquimico do Hg na referida região. Caracterizaram-se amostras de solo e de substâncias húmicas. Nos solos foram avaliados os seguintes parâmetros: teor de matéria orgânica, granulometria, teor de mercúrio, alumínio e ferro. As substâncias húmicas extraídas de solo da região do Rio Aracá-AM são relevantes por contribuírem no processo de complexação com íons metálicos, influindo na mobilização e biodisponibilidade de metais no compartimento solo. Utilizando-se um sistema de fracionamento em função do tamanho molecular obtiveram-se seis frações (F1>100; F2:100-50; F3:50-30; F4:30-10; F5:10-5 e F6<5 kDa). Para melhor compreensão da capacidade de complexação (CC) das substâncias húmicas de solo por íons cobre foram feitos experimentos de ultrafiltração nas frações. No capítulo 1 Para tratar os dados de solos da região do Rio Aracá-AM utilizou-se a técnica exploratória multivariada de análise hierárquica de agrupamento. Os dendogramas obtidos mostraram que os solos dessa região apresentam comportamentos similares. No capítulo 2 dentre as capacidades de complexação determinadas a região do Rio Aracá apresenta menor CC (0,21) quando comparadas a diferentes solos da Bacia do Rio Negro-AM. / Abstract: This work was intended to characterized different soils from Basin of Rio Negro-AM and specifically the region of Rio Aracá-AM and estimates its contribution to biogeochemical cycle of Hg in that region. Soil samples and humic substances extracted from them were characterized. Were determined on soils: organic matter, granulometry, quantity of mercury, aluminium and iron. The extracted humic substances of soil from region of Rio Aracá-AM have an important function due to their performance on complexing and releasing metallic ions. Six fractions were obtained using a fractionation system (F1>100; F2:100-50; F3:50-30; F4:30-10; F5:10-5 and F6<5kDa) in function of molecular size. To better comprehension of complexation capacity of humic substances by ions copper, were made experiments of ultrafiltraction on the fractions. In chapter 1 to treat characterization data was used the multivariate exploratory technique of analyze hierarchic of cluster. The results shows that soils from Rio Aracá - AM presents similar behavious. In chapter 2 between the complexation capacities determined from Rio Aracá presents the smaller values (0,21) than others on the Rio Negro Basin. / Orientador: Julio Cesar Rocha / Coorientador: André Henrique Rosa / Banca: José Pedro Serra Valente / Banca: José Carlos Marconato / Banca: Wilson Tadeu Lopes da Silva / Banca: Gilmar Silverio da Silva / Doutor

This project aims to analyze HI bacteria agents in clinical samples of patients and handswashing of health workers of four ITU in Manaus. Handswashing was performed in soy trypticasein broth and incubated at 37ºC for 24 hours. It was grown in medium for isolation and bacteria identification. The clinical samples were grown and identified in the same conditions as that of the handswashing. Out of the 294 handswashing samples, 244 bacteria were isolated, the most frequent were Enterococcus fecalis (32,79%), Staphylococcus aureus (24,18%), Pseudomonas aeruginosa (7,79%), Burkolderia cepacia (5,33%), Enterobacter cloacae (4,51%), Klebsiella pneumoniae (4,51%), and others (12,70%). Out of the 94 patients secretion samples collected, the most frequent were Staphylococcus aureus (39,36%), Pseudomonas aeruginosa (18,08%), Acinetobacter baumannii (4,25%), Enterobacter cloacae 93,19%), Enterococcus fecalis (4,25%), Serratia marcescens (9,57%) and others (11,72%). The most frequent pathogens isolated from the clinical and handswashing samples were analyzed for resistance through disc diffusion method. Also, it was performed a study of the health workers habits that could mean a risk factor for HI. Staphylococcus aureus isolated from the clinical samples presented a low rate of resistance to the antibiotics tested. The other microorganisms isolated from the clinical and handswashing samples showed a high rate of resistance to the several groups of antibiotics that are usually used for their treatment. This study analyzed the frequency of pathogens isolated from clinical and handswashing samples and the presence of pathogens that are multi-resistant to the several groups of antibiotics tested, showing the need of implementing strategies that raise awareness of training for HI knowledge and control. / A infecção hospitalar (IH) representa um dos graves problemas de saúde pública no Brasil e no mundo, proporcionando o aumento de morbimortalidade de pacientes internados principalmente em UTI´s. Esse projeto tem como objetivo analisar os agentes bacterianos desencadeadores de IH de amostras clínicas de pacientes e lavados de mãos dos profissionais de saúde de 4 UTI´s do município de Manaus. A lavagem das mãos foi realizada em Caldo de Tripticaseina de Soja, foi incubado por 24h a 37ºC. Semeado em meio de cultivo para isolamento e identificação das bactérias. As amostras clínicas foram semeadas e identificadas nas mesmas condições dos lavados de mãos. De 294 amostras do lavado de mãos foram isoladas 244 bactérias, sendo as mais freqüentes Enterococcus fecalis (32,79%), Staphylococcus aureus (24,18%), Pseudomonas aeruginosa (7,79%), Burkolderia cepacia (5,33%), Enterobacter cloacae (4,51%), Klebsiella pneumoniae (4,51%) e outras (12,70%). Das 94 amostras coletadas de secreções de pacientes foram isoladas 94 bactérias, as mais freqüentes foram Staphylococcus aureus (39,36%), Pseudomonas aeruginosa (18,08%), Acinetobacter baumannii (4,25%), Enterobacter cloacae (3,19%), Enterococcus fecalis (4,25%), Serratia marcescens (9,57%) e outras (11,72%). Os patógenos isolados de maior freqüência de amostras clínicas e lavados de mãos foram avaliados quanto ao perfil de resistência pelo método de difusão em disco. Também foi realizado um estudo sobre os hábitos dos profissionais de saúde que possam ser considerados como fatores de risco para IH. Staphylococcus aureus isolados de amostras clínicas, mostraram um baixo índice de resistência aos antibióticos testados. Todos os outros microrganismos isolados dos lavados de mãos e de amostras clínicas mostraram uma elevada taxa de resistência a vários grupos de antibióticos, normalmente, utilizados no seu tratamento. O presente estudo avaliou a freqüência dos patógenos isolados de amostras clínicas e lavados de mãos e a presença de patógenos multi-resistentes a vários grupos de antibióticos testados, além de evidenciar a necessidade de implantar estratégias que desenvolvam maior conscientização e capacitação para o controle de IH

Esta estruturação foi delineada através da compartimentação morfotectônica do Interflúvio Solimões-Negro, objetivo desta pesquisa. As discussões concentram-se na área de distribuição das coberturas cenozóicas superposta às bordas leste e oeste das bacias sedimentares paleozóicas do Solimões e Amazonas, respectivamente. Esta área ocupa cerca de 290 000 Km²,e localiza-se entre os paralelos 0° e 4°S e meridianos 60°WGr, na região amazônica, envolvendo principalmente o Estado do Amazonas e parcela do Estado de Roraima. As unidades geológicas formadas durante ou após a implantação do regime neotectônico estão representadas: 1) pela Formação Içá de idade pós-miocênica provavelmente plio-pleistocênica; 2) por Terraços Pleistocênicos; 3) por Terraços Holocênicos; 4) pelas Áreas Inundáveis Interfluviais Holocênicas; e 5) pelos Aluviões Holocênicos. O modelamento da paisagem pela rede de drenagem evidencia uma compartimentação do relevo em sistemas de planícies, ligados à dinâmica fluvial atual,e em sistemas de interflúvios tabulares normalmente nivelados por uma superfície de aplainamento formada na metade do Pleistoceno, em retomada de erosão. A estruturação neotectônica tem um relacionamento direto com a regeneração das descontinuidades pertencentes à estruturação paleotectônica, isto é, com a tectônica ressurgente. Esta estruturação antiga é definida por:1) Lineamento Tacutu de orientação NE-SW, que se projeta para o quadrante noroeste da área; 2) o Lineamento Madeira, também de orientação NE-SW que secciona o quadrante sudeste;3) o Arco de Purus com orientação NW-SE que estabelece os limites entra as bacias do Amazonas e Solimões; (4) lineamentos menores como Juruá e o Japurá, de direção E-W, definidos fora dos domínios da área pesquisada. A atuação do campo de tensões neotectônico foi aliviada através de dois pulsos de movimentação cinemática de natureza essencialmente transcorrente. No primeiro pulso ocorrido imediatamente após a inversão para leste da rede de drenagem da Amazônia Ocidental, que corria para oeste, estabeleceram-se os principais corredores de drenagem na direção predominante NE-SW através do nordeste do Amazonas, Roraima e Guyana, alcançando o Oceano Atlântico através do rift valley do Tacutu. O segundo, predominantemente transtensivo, ocorreu no Pleistoceno Superior - Holoceno, provocou o redirecionamento desse sistema para o Amazonas, e responde pela configuração do relevo e pelo desenho da rede de drenagem tal como se mostra atualmente. Os sistemas de Relevo diferenciam-se, fundamentalmente, pelo grau de desenvolvimento da rede de drenagem, havendo uma nítida gradação da mais evoluída para menos evoluída, que se reflete na distribuição dos interflúvios e nas suas dimensões, e que registram a história da implantação do quadro estrutural neoctectônico e suas diferenciações geométricas e cinemáticas. Este registro encontra-se especializado em cinco compartimentos morfotectônicos, denominados: Compartimento Transpressivo Rio Juruá-Rio Purus; Compartimento Transcorrente Rio Madeira-Rio Purus; Compartimento Transcorrente Rio Negro- Rio Japurá; Compartimento Transtensivo Rio Negro- Rio Solimões; e o Compartimento Transtensivo Rio Branco- Rio Negro. A evolução morfoestrutural e morfotectônica se deu de sudoeste para nordeste, de modo que a rede de drenagem encontra-se bem desenvolvida no Compartimento Rio Juruá-Rio Purus; em desenvolvimento na zona central formada pelos Compartimentos Rio Madeira-Rio Purus; Rio Negro- Rio Japurá e Rio Negro - Rio Solimões; encontra-se em estágio inicial de desenvolvimento no Compartimento Rio Branco- Rio Negro. A nordeste do Compartimento Transtensivo Ri Negro- Rio Japurá, a rede de drenagem é composta, apresentado tanto feições de estágio inicial como os padrões amorfo e multibasinal, quanto outras feições típicas de rede de drenagem em desenvolvimento. As estruturas do Compartimento Rio Juruá- Rio Purus compreendem falhas inversas geradas no Terciário Superior; as dos compartimentos Rio Madeira-Rio Purus e Rio Negro- Rio Japurá são falhas direcionadas dextrais com componente de rejeito oblíquo, provavelmente inverso no Terciário Superior e normal no Pleistoceno; no Compartimento Rio Negro-Rio Solimões são principalmente falhas normais e de rejeito oblíquo dextral do Pleistoceno Superior; e no Compartimento Rio Branco - Rio Negro configura-se uma estrutura em cunha com movimentação oblíqua nas bordas noroeste e leste, e extensional na sua zonal central, com evolução iniciada no Pleistoceno Superior estendendo-se ao Holoceno. Atividades recentes de algumas dessas falhas são marcadas por eventos sísmicos de intensidade que chegam a 5.5 mB. / From the morphostuctural and morphotectonic analysis integrated to the informations of remote sensing images, litoestratighaphy , geomorfology , the seismic data and field investigations was defined the neotectonic structuration and its influence in the elaboration of the relief forms and drainage net during the Upper Tertiary and Quaternary. This relation is shown through the morphotectonic compartimentation of the Solimões-Negro watershed, subject of this research (SA.20-Manaus Sheet). The discussions concentrated in the area of the cenozoics covers which overlay the east and west borders of the Solimões and Amazon paleozoics sedimentary basins, respectively. This area occupies about 290 000 km2, and is situated between the parallels 0° and 4° S and meridians 60° and 66° WGr, in the Amazonian region, involving parcels of Amazon and Roraima States. The geologic units formed during, or imediatelly after, the implantation of the neotectonic regimen are represented by: 1) the Içá Formation formed after the Miocene, probably of the Plio-Pleistocene age; 2) the Pleistocenics Terraces; 3) the Holocenics Terraces; 4) the inundatable watersheds areas of holocenic age; and 5) the Holocenics Alluviums. The modelling of the landscape for the drainage net evidences a relief compartimentation at plains systems, linked to the actual fluvial dynamics, and depressions, normally leveled by a planing surface formed in the Middle Pleistocene, in retaken by erosion, and preserved on tabular watershed. The neotectonic structuration has a direct relationship with the regeneration of the discontinuities of the paleotectonic structuration, that is, with the resurgent tectonic . This old estructuration is defined by: 1) Tacutu Lineament of NE-SO orientation, that show continuity to the northwest quadrant of the area; 2) the Madeira Lineament, also of NE-SO orientation that section the Southeastern quadrant; 3) the Purus Arc with NW orientation that establishes the limits between the Solimões and Amazon basin; e (4) minors lineaments as the Juruá and the Japurá ones, of E-O direction, defined outside of the domains of the research area. The neotectonic tensions field was alliviated through two kinematics pulses of essentially transcorrent nature. In the first pulse, occurred immediately after the inversion of the Amazonian Occidental drainage for east, had established the main corridors of drainage in the predominant NE-SO direction through the northeast of Amazonas and Roraima states in the brasilian territory, reaching the Guyana Republic and the Atlantic Ocean through rift valley of the Tacutu. The second one, predominantly transtensive, occurred in the Upper Pleistocene /Holocene, provoked the redirectioning of this system for the Amazonas hidrographic basin, and answers for the actual configuration of the relief and drainage net. The Relief Systems are differentiate for the degree of development of the drainage net, showing a evident gradation from the most evolued to the less evolued, that is reflected in the configuration of the watershed and its dimensiona, and that register the history of the implantation of the neotectonic structural picture and its geometric and kinematic differentiations. This register is represented through five morfotectonics compartments, called: Juruá River - Purus River Tanspressive Compartment; Madeira River - Purus River Transcorrent Compartment; Negro River- Japurá River Trancorrent Compartment; Negro River - Solimões River Trantensive Compartment; and the Branco River- Negro River Transtensive Compartment. The morphostructural and morphotectonic evolution occurred from southwest to northeast. So, the drainage net show best developed in the Juruá River — Madeira River Compartment; it is in development in the central zone formed by the Madeira River - Purus River, Negro River-Japurá River and Negro River- Solimões River Compartments; and show a initial stage of development in the Negro River- Branco River Compartment. In the northeast border of the Negro River Japurá River Transtensive Compartment, the development of the drainage net is composed, showing features of initial stage, as the amorphous and multibasinal pattern, with other typicals features of drainage net in development. The structures of the Juruá River Purus River Compartment are generated by inverse faults in the Upper Tertiary. In the the Madeira River - Purus River and Negro River — Japurá River compartments they are dextrals directional faults with component of oblique slip, probably of the reverse type in the Tertiary Superior and normal in the Pleistocene; in the Negro River - Solimões River Compartment they are mainly normal and oblique-dextrais types in the Upper Pleistocene. The Negro River- Branco River Compartment configures a wedge structure with oblique movement in the northwest and east borders, and extensional in its central zone, with evolution initiated in the Upper Pleistocene extending to the Holocene. Recent activity of some of these faults is marked by seismic events with intensities that arrive 5,5 mB.
