Adopting an eclectic analytic perspective of discourse analysis, conversation analysis and functional approaches, this study conducts an in-depth pragmatic analysis and describes the function of three pragmatic particles yani, iSte and Sey in casual, conversational Turkish. All three particles have multiple functions, which are described by reference to occurrences in utterances within three different domains of conversation. While utterance initial occurrences of yani are mainly connective and continuative, the utterance final placement of yani mainly acts as a situating particle with a strongly interactional nature. The utterance medial occurrences are basically &lsquo / self-editing&rsquo / whereby the speaker marks the clarification of a point in his/her prior talk. iSte mainly acts as a frame particle demarcating utterances as containing detailed, highlighted, and reported information as well as connecting distant pieces of utterances. The third particle Sey basically marks the speaker&rsquo / s temporary mental effort of extracting the linguistic information from the memory. In addition to its major role in repair organisation whereby marking its producer&rsquo / s verbal planning and word search, Sey displays caution and discretion and marks politeness when assessing/asserting something about the self or the other.

This thesis examines museum development in the two post-colonial settler societies of Australia and Aotearoa New Zealand, investigating the evolution of new histories as museums seek to aid the construction of post-colonial national identities. Drawing on a wide body of evidence on an under-researched topic, the thesis is arranged in two parts. The first presents a survey of how traditional images of national identity have been created, sustained and more recently challenged during the histories of Australia and New Zealand - illustrating that the question of non-indigenous national identity is a problematic one. It then provides a historical narrative of museums in both countries. Highlighting the differences and similarities between the two countries and focusing on the development of historical collections, it explores how museums have perpetuated traditional interpretations of nation, and how in recent decades various factors have combined to challenge conventional museum practice, making the role and function of museums at the beginning of the twenty-first century particularly complex. The second part focuses on the new National Museum of Australia in Canberra and the Museum of New Zealand Te Papa Tongarewa in Wellington. It combines an examination of their history with an analysis of how they attempt to convey ideas of nation and national identity. Both museums have opened recently, at a time when national museums around the world are confronted with an increasingly prominent and challenging political and social role in society, and an especially difficult, perhaps impossible, task of representing all the different histories that constitute the ‘nation’.

[Truncated abstract] Infrared (IR) detectors have many applications, from homeland security and defense, to medical imaging, to environmental monitoring, to astronomy, etc. Increasingly, the wave- length dependence of the IR radiation is becoming important in many applications, not just the total intensity of infrared radiation. There are many types of infrared detectors that can be broadly categorized as either photon detectors (narrow band-gap materials or quantum structures that provide the necessary energy transitions to generate free car- riers) or thermal detectors. Photon detectors generally provide the highest sensitivity, however the small transition energy of the detector also means cooling is required to limit the noise due to intrinsic thermal generation. This thesis is concerned with the tech- nique of resonant-cavity-enhancement of detectors, which is the process of placing the detector within an optically resonant cavity. Resonant-cavity-enhanced detectors have many favourable properties including a reduced detector volume, which allows improved operating temperature, or an improved signal to noise ratio (or some balance between the two), along with a narrow spectral bandwidth. ... Responsivity of another sample annealed for 20 hours at 250C in a Hg atmosphere (ex-situ) also shows resonant performance, but indicates significant shunting due the mirror layers. There is good agreement with model data, and the peak responsivity due to the absorber layer is 9.5×103 V/W for a 100 'm ×100 'm photoconductor at 80K. An effective lifetime of 50.4 ns is extracted for this responsivity measurement. The responsivity was measured as a function of varying field, and sweepout was observed for bias fields greater than 50 V/cm. The effective lifetime extracted from this measurement was 224 ns, but is an over estimate. Photodiodes were also fabricated by annealing p-type Hg(1x)Cd(x)Te for 10 hours at 250C in vacuum and type converting in a CH4/H2 reactive ion etch plasma process to form the n-p junction. There is some degradation to the mirror structure due to the anneal in vacuum, but a clear region of high reflection is observed. Measurements of current-voltage characteristics at various temperatures show diode-like characteristics with a peak R0 of 10 G measured at 80K (corresponding to an R0A of approximately 104 cm2. There was significant signal from the mirror layers, however only negligible signal from the absorber layer, and no conclusive resonant peaks.

Les électrodes transparentes sont intégrées dans de nombreux dispositifs optoélectroniques tels que (les OLED, les cellules photovoltaïques, les écrans tactiles...). De nos jours, l’électrode transparente la plus utilisée est l’oxyde d’indium dopé étain (ITO : Indium Tin Oxide) qui présente une transparence élevée et une faible résistance carrée. Malgré ces propriétés optoélectroniques exceptionnelles, l’ITO présente des inconvénients tels que la rareté de l’indium et sa fragilité qui est incompatible avec les substrats flexibles. Les nanofils d’argent (AgNWs) sont considérés comme une alternative potentielle pour remplacer l’ITO en vue de leur excellentes propriétés optoélectroniques et leur flexibilité. Néanmoins, les AgNWs souffrent de certains inconvénients (adhérence au substrat, rugosité). Dans ce travail nous proposons une structure de type Oxyde/Métal/Oxyde (OMO) en insérant une couche d’AgNWs comme couche métallique entre deux couches de nanoparticules d’oxydes (ZnO, AZO, WO3) pour fabriquer des électrodes tricouches de type ZAZ, AAA et WAW. Ces dernières ont montré transmission élevée combinée à une faible résistance carrée, ce qui leur permet d’être considérées comme des électrodes alternatives à l’ITO. De plus, les électrodes ZAZ et AAA ont été intégrées avec succès dans des cellules solaires organiques. En outre, un outil numérique potentiel utilisant la méthode FDTD (Finite Difference Time Domain) nous permis de confirmer les résultats expérimentaux pour les électrodes ZAZ. Ainsi, l’amélioration de l’absorption au sein de la couche active via l’effet plasmonique des AgNWs a été démontrée également. Finalement, nous avons pu modéliser un réseau semi-aléatoire des AgNWs inséré entre deux couches de ZnO tout en démontrant la différence en transmission entre une couche dense et une en nanoparticules de ZnO. / Transparent Electrodes (TEs) are crucial components of wide variety of optoelectronic devices as (OLEDs, photovoltaic cells, touch screen…). Nowadays, the transparent electrode widely used is Indium Tin Oxide (ITO), due to its good optoelectronic properties. However, it presents some drawbacks such as the indium scarcity and its brittleness which is not compatible with flexible substrates. Silver nanowires (AgNWs) were considered as potential alternative to replace ITO because of their good optical and electrical properties. Although promising, the AgNWs presents some drawbacks, including the poor adhesion to substrate and the surface roughness. In this work, we propose a sandwich structure Oxide/Metal/Oxide (OMO), where the metallic layer is based on AgNWs. We embedded AgNWs between two nanoparticles oxide layers of (ZnO, AZO, WO3) in order to fabricate trilayer electrodes which are ZAZ, AAA, WAW. These trilayer electrodes show a high transmittance and a low sheet resistance, which lead to consider them on of the alternative to the ITO. In addition, the ZAZ and AAA electrodes were successfully integrated in organic solar cells with good photovoltaic performance. Moreover, using the potential numerical method FDTD (Finite Difference Time Domain) we demonstrated a good agreement between the experimental and numerical results for the ZAZ electrodes. Therefore, the enhancement of absorption inside active layer due to the plasmonic effect of AgNWs was also demonstrated. Finally, we can model a randomly network of AgNWs embedded between two layers of ZnO, with investigating the difference between a dense and nanoparticles layer of ZnO.

A ênfase deste t rabalho está vol tada à utilização da simulação computacional dentro do contexto do processo de desenvolvimento de produto. Foi utilizado o método dos elementos finitos para simular o teste de bancada que é realizado para val idar a resistência mecânica e a capacidade de absorção de energia de estruturas de proteção contra capotamento (EPCC) de t ratores agrícolas. Foi feita uma proposta de design de uma cabina para t ratores estreitos e a parti r dela foi executado o teste vi rtual para a sua validação. A simulação foi fei ta considerando as característ icas não lineares dos materiais, uma vez que a deformação atinge o regime plástico dos mesmos. Como a cabina é uma est rutura soldada relativamente complexa, foram feitas idealizações para se reduzi r o tempo computacional. De posse dos resultados vi rtuais, foi possível prever as regiões mais e menos solici tadas da estrutura sem a necessidade de real izar o teste real, propondo assim alterações de design e de materiais da cabina para tornar a absorção da energia de deformação mais eficiente. / The emphasis of this work is focused on the use of computer simulation within the context of product development. The finite element method was used to simulate the real test that is conducted to validate the st rength and energy absorption capacity of rollover protective st ructures (ROPS) of agricul tural tractors. From a design proposal of a cab to a narrow tractor, the test was performed to validate it . The simulation was made by adopt ing the nonlinear characteristics of the materials, since the deformation reaches the plastic regime. As the cab is a welded structure relatively complex, idealizations were made to reduce the computational time. With the results vi rtual , it was possible to predict the most and least requested regions of the st ructure without the need to run the real test, proposing design and material changes to make the absorption of strain energy more efficiently.

No primeiro estudo, utilizou-se líquido de rúmen de um novilho em pastejo, com adição de solução de tripticase, em três tratamentos (controle-C; monensina-M; e própolis-P). Foram feitas transferências diárias de inóculos para novos tubos com os mesmos tratamentos até o 10 o dia (1 a fase) e, no 11 o dia, cada tratamento foi combinado com os mesmos tratamentos da 1 a fase (C, M, P), totalizando nove combinações que continuaram a serem transferidos diariamente, sendo incubados durante mais nove dias (2 a fase). Do 1 o ao 10 o dia de incubação (1 a fase), a adição de ionóforo e da própolis a cultura evitaram o aumento da produção de amônia comparado ao controle. A própolis foi mais eficiente em decrescer a produção de amônia do que a monensina na 1 a fase; e diminui a produção de amônia e a AEPA na 2 a fase independente do tratamento presente na 1 a fase. A monensina foi tão eficiente quanto a própolis, na 2 a fase, quando os inibidores estavam ausentes na 1 a fase. Verificou-se, que ao remover os inibidores na 2 a fase, houve aumento na produção de amônia, quando o tratamento foi monensina, mas este efeito não foi detectado quando o tratamento era própolis, mantendo amônia em baixas concentrações. No segundo estudo, foram utilizadas três vacas Holandesas, fistuladas no rúmen, em delineamento completo, em dois blocos, com três períodos experimentais cada um. Os tratamentos constituíram de adição de três níveis de extrato etanólico de própolis (0, 34 e 68 mL/animal/dia) as dietas. As dietas foram compostas de 64,4% de silagem de milho e 35,6% de concentrado à base de milho e farelo de soja. Houve efeito de tratamentos sobre produção de leite, teor de gordura e proteína do leite, porcentagem de lactose no leite, consumo de matéria seca, eficiência alimentar, concentração de NH 3 ruminal, às zero e três horas de coleta e pH às zero e três horas de coleta. Entretanto, não houve efeito de tratamento sobre a percentagem de gordura, proteína e extrato seco do leite, e AEPA pelas bactérias ruminais. O extrato etanólico de própolis adicionado à dieta aumenta o consumo de matéria seca e a eficiência alimentar e a produção de leite, e teor de gordura e proteína do leite, de vacas lactantes. / Two experiments were performed to compare the effects of ethanolic extract of propolis and monensin in hipper ammonia producer microorganisms, and to observe the effects of levels propolis extract in the diets of dairy cows on: (1) ruminal parameters (ammonia, pH, and specific activity of ammonia production [SAAP] by the ruminal microbial population), in vitro, and (2) ruminal parameters, dry matter intake and production and composition of milk. In the first experiment, rumen fluid from a grazing steer was used, with addition of tripticase solution, in three treatments (control-C; monensin-M; and propolis-P). Inocula were transferred daily into new tubes up to the 10 th day (first phase). On the 11 th day, each treatment were combined with the same treatment in the 1 st phase (C, M, P), totalizing nine combinations that continually to be daily transferred , being incubated during more nine days (second phase). From the 1 st to the 10 th days of incubation (1 st phase), addition of ionophore and propolis to culture media prevented increases in ammonia production compared to the control. Propolis was more efficient than monensin in decreasing ammonia production in the 1 st phase; and decreased ammonia production and SAAP in the 2 nd phase regardless of the treatment present in 1 st phase. Monensin was as much efficient as propolis in the 2 nd phase, when the inhibitors were absent in the 1 st phase. By removing the inhibitors in the 2 nd phase, there was increase in ammonia production, when the treatment was monensin, but this effect was not observed when propolis was used, keeping ammonia at low concentrations. On the second experiment, three rumen fistuled dairy Holsteins cows were used, in switch-back design, in two blocks, witch three experimental periods each one. The treatments consisted of the crescent levels ethanol extract of propolis addition (0, 34, 68 mL/animals/day) to the diets. The diets were composed by 64.4 corn silage and 35.6% concentrate based on ground corn and soybean meal. There was effect of treatments on milk production, content of fat and protein of the milk, percentage of milk lactose, dry matter intake, feed efficiency, ruminal NH 3 concentration at 0 and 3 hours of collection and pH at 0 and 3 hours of collection. ixHowever, there was not effect of treatment on the percentage fat and protein, dry extract of milk, and SAAP by the ruminal bacterias. The ethanol extract of propolis added to the diet increase intake of dry matter and feed efficiency, and milk production, and content of fat and protein of milk of lactating dairy cows.

Este trabalho tem como objetivo analisar a peça Não te assusta, Zacaria!, estreada em Porto Alegre, no Theatro São Pedro, em 6 de abril de 1956, com texto e direção de Barbosa Lessa, com base no método de análise contextual. Marco de Marinis (1997) descreve esse método de análise como “uma prática exegética particular, ou seja, ler os documentos e relacioná-los com outros documentos, iluminando-os e complementando-os reciprocamente”. Em nosso caso, implica que não nos restringimos à análise do texto dramático e à discussão do texto espetacular de Não te assusta, Zacaria! – também detalhamos e analisamos os vários contextos que serviram de pano de fundo para sua criação, sejam eles sociais, econômicos, políticos, culturais ou estéticos. Para tanto valemo-nos de documentos como o roteiro dramático da peça, da pesquisa bibliográfica e em arquivos de jornais e revistas da época, e de depoimentos colhidos junto a pessoas envolvidas diretamente na produção, jornalistas que cobriram a peça, artistas ligados ao teatro àquele tempo em Porto Alegre e público que esteve na plateia de Não te assusta, Zacaria!. / This paper aims at carrying out a contextual analysis of the play Não te assusta, Zacaria!, written and directed by Barbosa Lessa and performed at the São Pedro Theater, in Porto Alegre, on April 6, 1956. Marco de Marinis (1997) describes the contextual analysis as "an exegetical practice that involves reading documents and relating them to other documents, enlightening them and complementing one another". In our case, this implies that the analysis will not be restricted to the dramatic or the spectacular text of Não te assusta, Zacaria!, but that it will take into consideration the contextual background of its creation, namely the social, economic, political, cultural or aesthetic circumstances surrounding both its playwriting and its performance. The documents analyzed include the script, newspapers and magazines clippings about the performance and testimonies given by the people directly involved in the production, journalists covering the play, actors and other artists who participated in the cultural scene of Porto Alegre at that time and spectators.

A presente tese tem por objetivo investigar as dinâmicas de apropriações humorísticas (com ênfase na questão da imagem, mas considerando o que é da ordem textual) de celebridades em blogs. Persegue-se, com isso, examinar como tais dinâmicas de apropriações vinculam-se às diferentes categorias de celebridades e expressões do humor. O referencial teórico do trabalho abrange uma revisão sobre a temática das celebridades e os autores relevantes do campo definido como celebrity studies, as articulações entre humor, riso e comicidade — e como o fenômeno do digital trash tem permeado as lógicas de apropriações humorísticas no contexto da web, além de problematizar o conceito de apropriação a partir de áreas distintas, tais como as artes visuais, a filosofia da linguagem e a comunicação. Para operacionalizar a pesquisa, elabora-se uma análise comparativa entre as postagens de dois blogs de humor sobre celebridades: o “Morri de Sunga Branca” e o “Te Dou Um Dado?”. Esta análise tem seu caráter qualitativo amparado em dados quantitativos, a partir da coleta de dados da produção de ambos os blogs entre os meses de Abril e Setembro de 2014 (resultando em um total de 81 postagens do “Morri de Sunga Branca e 351 do “Te Dou Um Dado?”). Também foram extraídos os dados das fanpages dos blogs no Facebook, utilizando-se o aplicativo Netvizz, de modo a observar o direcionamento das postagens para o ambiente dos blogs, bem como averiguar aspectos relativos às métricas e processualidades de cada um deles. Os resultados demonstram indícios de que a quantidade de postagens não significa, necessariamente, maior retorno em métricas para um blog, e apontam para um conjunto de 7 recursos comuns de apropriação no que se refere às imagens, tanto em um ambiente como em outro. Tais recursos constituem-se de: fotografia, GIF, montagem, screenshot de site, screenshot de site de rede social, screenshot de frame — de vídeo, de programa televisivo ou filme — e vídeo. Por fim, como desdobramento da análise, se verifica a existência de um conjunto de tipos de celebridades que aparecem, de forma geral, em blogs como estes. Assim, com base em autores que já haviam estabelecido algum tipo de categorização de conjunto de celebridades formula-se uma proposta de tipologia de celebridades levando-se em consideração o que se viu nas postagens do “Morri de Sunga Branca” e do “Te Dou Um Dado?”. A tipologia em questão contempla as seguintes categorias — sendo as cinco primeiras ancoradas em Rojek (2008): Celebridade Adquirida (dividida entre Global e Local), Celebridade Atribuída, Celebridade Conferida, Celetóide, Celeator, Webcelebridade, Celebridade Fronteiriça e Sujeito Tangencial à Visibilidade Midiática. / This thesis’ main objective is to investigate the dynamics on the comical appropriation (with an emphasis on imagery, but also considering the textual aspect) of celebrities on blogs. We thus examine how these dynamics of appropriation are linked to the different celebrity categories and humor expressions. Our theoretical approach encompasses a review of the theme of celebrity and the relevant authors on the field of celebrity studies, the links among humor, laughter and comicality – and how the phenomena of digital trash has permeated the logic in humorous appropriation on the Web, as well as analyzing the concept of appropriation from distinct areas such as visual arts, philosophy of language, and communication. The method of the research is a comparative analysis of posts on two Brazilian humor blogs on celebrities: “Morri de Sunga Branca” and “The Dou um Dado?”. The qualitative analysis is supported by quantitative data, from data collection pertaining to the publishings of both blogs from April through September of 2014 (a total of 81 posts from “Morri de Sunga Branca” and 351 from “Te Dou um Dado?”). We also collected data from their fan pages on Facebook using the app Netvizz to better observe the redirectioning from these posts to the blog platform, and to investigate metrics and processes of each of them as well. The results show signs that the quantity of posts does not necessarily mean highest metrics on the blogs, and point to a set of 7 common appropriation resources of the images, on both sites. These resources are: photographs, GIF, collage, website screenshots, social networks screenshots, frame screenshots – of a video, TV program or motion picture – and video. Lastly, as a development of the analysis, we may observe a set of subtypes of celebrities that are generally featured on blogs like these. Based on authors who had already proposed some sort of categorization of types of celebrities, we propose a typology of celebrities based on data extracted from posts of “Morri de Sunga Branca” and “Te Dou um Dado?” – the first five types as proposed by Rojek (2008): Ascribed Celebrity (Global or Local), Achieved Celebrity, Attributed Celebrity, Celetoid, Celeactor, Web celebrity, Borderline Celebrity and Person Subject to Tangential Media Visibility.
