Airships provide an eco-friendly and cost-effective means to suit sustained airborne operations. Smaller autonomous airships are highly susceptible to adverse atmospheric conditions owing to their under-actuated, underpowered and bulky size relative to other types of unmanned aerial vehicles (UAVs). To mitigate these limitations, careful considerations of the size and shape must be made at the design stage. This research presents a methodology for obtaining an optimized shape of a semi-rigid airship. Rapid descent of the LTA ship is achieved by means of a moving gondola attached to a rigid keel mounted under the helium envelope from the bow to the mid-section of the hull. The study entails the application of a robust hybrid genetic algorithm (HGA) for the multi-disciplinary design and optimization of an airship capable of rapid descent, with lower drag and optimum surface area. A comprehensive sensitivity analysis was also performed on the basis of algorithmic parameters and atmospheric conditions. With the help of HGA, a semi-rigid airship capable of carrying a payload of 0.25 kg to 1.0 kg and capable of pitching at right angles is conceptually designed. The algorithm is also tested on commercially available vehicles to validate the results. In multi-objective optimization problems (MOOPs), the significance of different objectives is dependent on the user.

This thesis intervenes in current critical debates about space, place and landscape in late-twentieth and twenty-first century British and Irish poetry, by examining models of excavation in selected work by Geoffrey Hill, Ciaran Carson, Geraldine Monk and Alice Oswald. It argues that the influence of the spatial turn on literary criticism over the last thirty years has led to the deployment of a limited set of spatial tropes as analytical tools for interpreting the spaces and places of poetry. By deploying excavation as a critical method it seeks to challenge existing approaches that tend to privilege ideas of space over time, and socio-spatial practices over literary traditions of writing place. In doing so it develops a new model for reading contemporary poetries of place that asserts the importance of locating spatial criticism within temporal and literary-historical frameworks. The four poets examined in the thesis exhibit a common concern with unearthing the strata of language as well as material space. Starting from a premise that excavation always works over the ground of language as well as landscape it investigates the literary traditions of landscape writing in which each of these poets might be said to be embedded. After surveying the critical field the thesis sets out four principles of excavation that it argues are transformed and renewed by each of these poets: the relationship between past and present; recovery and interpretation of finds; processes of unearthing; exhumation of the dead. The subsequent chapters contend that these conventions are put into question by Geoffrey Hill’s sedimentary poetics, Ciaran Carson’s parodic stratigraphy, Geraldine Monk’s collaborations with the dead, and Alice Oswald’s geomorphology of a self-excavating earth. The critical method that underpins the discussion in each of the chapters is also excavatory in that it unearths both the historical and literary strata of specific sites (the Midlands, Belfast, East Lancashire, Dartmoor and the Severn estuary) and resonances in the work of earlier poetic excavators (Paul Celan, Edward Thomas, Gerard Manley Hopkins, William Wordsworth, Dante Alighieri and Homer). Through careful exegesis of these poets and their precursors this thesis demonstrates that by transforming existing forms of excavation, contemporary poetry is able to renew its deep dialogue with place and literary history.

More in National Parks, Protected Areas category always linked to major visitation. This project was carried out monitoring of visitation, one of the most beautiful scenery in the state of Santa Catarina -Brazil, Church Hill, which overlooks the Holed Stone, geological monument, inserted in the São Joaquim National Park, established by Decree 50.922 of July, 06/1961. Natural Protected Area (NPA) in the year 2013 was the fourth most visited country. Leveraging the installation of a physical ordinance on the access road to the Church Hill, observed traffic flow of visitors on the highway and after analysis of more than five thousand hours of effective monitoring, we found your profile, highlighting: number of visitors, time of visit, place of origin and used vehicle. In addition to assessing the physical aspects of the path and the parking spot, we estimated the tourism carrying capacity and the attractive alternatives to qualify this visitation. Among the actions effected include: signaling, identification of the visitor and the audioguide. All activities were followed, most with direct observation and through other interviews, and realized the reduction of congestion in the area, visitor awareness as to the location that is knowing and increased visitation time. Finding solutions to the demands of the population, the scientific community and the tourist market, combining them with the lowest possible impact on local visitation and surroundings, is a challenge for environmental management of any Protected Natural Area / Atualmente as Áreas Protegidas Naturais (APN) são roteiros turísticos muito procurados no Brasil e no mundo inteiro, porém conciliar a preservação da natureza e da proteção do patrimônio histórico-cultural para a gestão das mesmas, não é uma tarefa fácil. Ainda mais em Parques Nacionais, categoria de Unidades de Conservação sempre vinculadas a grande visitação. Neste trabalho realizou-se o monitoramento da visitação, num dos cenários mais belos do estado de Santa Catarina-Brasil, o Morro da Igreja, de onde se avista a Pedra Furada, monumento geológico, inserido no Parque Nacional de São Joaquim, criado pelo Decreto 50.922 de 06 de julho de 1961. Área Protegida Natural (APN) que no ano de 2013 foi a quarta mais visitada do país. Aproveitando a instalação de uma portaria física na estrada de acesso ao Morro da Igreja, observou-se o fluxo de veículos de visitantes na rodovia e após a análise de mais de cinco mil horas efetivas de monitoramento, constatou-se o perfil dos visitantes, destacando-se: quantidade dos mesmos, tempo de visitação, local de origem e veículo usado. Somado à avaliação dos aspectos físicos do trajeto e do local de estacionamento, estimou-se a capacidade de carga turística do atrativo e as alternativas para qualificar esta visitação. Entre as ações efetivadas destacam-se: a sinalização, a identificação do visitante e o áudio guia. Todas as atividades foram acompanhadas, a maior parte com observação direta e outras por meio de entrevistas, e percebeu-se a diminuição dos congestionamentos na área, a conscientização do visitante quanto ao local que está conhecendo e o aumento do tempo de visitação. Encontrar soluções às demandas da população, da comunidade científica e do mercado turístico, conciliando-as como menor impacto possível nos locais de visitação e entorno, é um desafio para a gestão ambiental de qualquer Área Natural Protegida

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Neste trabalho, um estudo da influencia da seleÃÃo de variantes sobre a cristalografia apÃs a transformaÃÃo martensÃtica no Maraging foi feito. O estudo cobriu a transformaÃÃo sob deformaÃÃo elÃstica e tambÃm sob deformaÃÃo plÃstica. No aÃo Maraging, austenita se transforma em martensita eu uma temperatura em torno de 200ÂC, nÃo importando a velocidade de resfriamento. Para simular a transformaÃÃo durante a deformaÃÃo elÃstica, ensaios de traÃÃo foram feitos em um forno acoplado a uma mÃquina de ensaios universais com uma tensÃo aplicada abaixo do limite de escoamento do material. A amostra foi aquecida atà 850ÂC, o forno foi aberto e a amostra resfriada ao ar sob tensÃo constante. Para estudar a influencia da deformaÃÃo plÃstica antes da deformaÃÃo, amostras foram deformadas plasticamente na temperatura acima da Ms (temperatura de inÃcio da martensita), a forÃa externa atuando sobre a amostra foi removida e o material sofreu a transformaÃÃo martensÃtica por resfriamento ao ar. Figuras de pÃlos foram medidas por EBSD (Electron Back-Scatter Diffraction) em ambas as condiÃÃes e comparadas com as figuras de pÃlos calculadas assumindo os modelos de Patel-Cohen e Taylor-Bishop-Hill. A orientaÃÃo da austenita mÃe foi obtida por envelhecimento na temperatura de 650ÂC e pelo uso de grÃos austenÃticos reconstruÃdos matematicamente. Os resultados mostraram que o modelo de Patel-Cohen foi mais adequado para a deformaÃÃo elÃstica enquanto que Taylor-Bishop-Hill foi melhor para a deformaÃÃo plÃstica. / In this work a study of the influence of variant selection on the crystallography after martensitic transformation in Maraging was studied. The study covered both the transformation under elastic deformation and also during plastic deformation. In Maraging steel, austenite becomes martensite at a temperature around 200oC regardless of the cooling speed. To simulate the transformation during elastic deformation, a tensile test was performed in a furnace attached to a universal testing machine with an applied stress below the yield strength of the material. The specimen was heated to 850o C, the furnace was opened and the sample cooled in air under a constant stress. To study the influence of plastic deformation before transformation, samples were plastically deformed in a temperature above Ms (martensite start temperature), the external force acting on the sample was removed and the material was allowed to transform into martensite by cooling in air. Pole figures were measured by EBSD (Electron Back-Scatter Diffraction) in both conditions and compared with calculated pole figures assuming Patel-Cohen model and Taylor-Bishop-Hill model. The orientation of the parent austenite was obtained either by reversing the austenite by heating at 650  C and by using the mathematically reconstructed austenite grains. Results showed that Patel-Cohen model were more suitable to elastic deformation while Taylor-Bishop-Hill model was more appropriated to plastic deformation.

This study presents the results of research that consisted of the verification of potentialities and perspectives on the practice of ecotourism activities at Itabaiana Hill, and considers the institutional, legal, economical, ecological, and cultural dimensions of its sustainability. Itabaiana Hill is a Conservation Unit in the phase of implementation as an ecological station since 1978. As such, its use is restricted to preservation, scientific research and environmental education. In the face of the occurrence of conflicts and the dissatisfaction of the nearby communities, due to the prohibition of the Hill s use, we understand ecotourism as a conciliatory activity between the local communities development and nature preservation. Environmental preservation and tourism activity are compatible and they can allow the maintenance of culture and income generation of the populations near the Conservation Units. In ecotourism, nature is the attracting consumable and its practice is based on the ethics of sustainability that understands nature as a natural and cultural asset. The variables adopted were based on the studies of Beni (2002) and Bóullon (2002), supported by the dimensions of sustainability. As research instruments, bibliographical and documental sources, interviews, visits to Itabaiana Hill with geographical reference to tourist points, and photographic records were used. The natural complex that forms Itabaiana Hill, 669m high, is easily noticed against the low landscape around it and was taken as a macro-scenery, subdivided into four potential units for ecotourism: the summit, the West vertex, the East vertex, and the valleys. Its morphology presents an almost vertical and rocky vertex to the West and another one with a softer declination to the East. This vertex is covered by rupestrian fields, cerrados (woodland/savanna regions in South America), restinga (coastal vegetation), and mata atlântica (Atlantic forest), through which four springs with riverbeds with waterfalls, and small basins of accumulation that form natural swimming pools flow, covered by gallery forest, making up a number of ecosystems of great value, that justify restrictions to the use of the area. Another relevant aspect that was identified consists of the incorporation of various elements of the Hill into the culture of Sergipe through stories and legends, which turns it into a special and potential place for ecotourism. As for the perspectives related to the opening of Itabaiana Hill to the use of ecotourism, the interviews conducted with landowners in the area, tourism agencies, tour guides, municipal and state organs, and IBAMA Brazilian Institute of Environment and Renewable Natural Resources supported our understanding that the use of ecotourism presents itself as a possible alternative, once there is a change made in the typology of the Conservation Unit, from an Ecological Station to another compatible type. Although there is already a study being developed by IBAMA, supported by Law # 9.985/2000 that instituted the National System of Conversation Units (SNUC), and that encourages ecotourism in Conservation Units and their surrounding areas as an alternative for development, a retrospective analysis of the process demonstrates a lack of involvement and commitment, at various levels, by the ones socially and institutionally involved with the preservation of the natural and cultural assets that constitute Itabaiana Hill. / Este estudo apresenta os resultados da pesquisa que consistiu na verificação das potencialidades e perspectivas da prática da atividade ecoturística na Serra de Itabaiana, considerando as dimensões institucional, legal, econômica, ecológica e cultural de sua sustentabilidade. A Serra de Itabaiana é uma Unidade de Conservação em fase de implantação como estação ecológica desde 1978. Como tal, seu uso é restrito à preservação, à pesquisa científica e à educação ambiental. Em face da ocorrência de conflitos e insatisfação das comunidades do entorno devido às proibições de uso, entendemos o ecoturismo como atividade conciliadora entre desenvolvimento e preservação da natureza. Preservação ambiental e atividade turística são compatíveis e podem permitir a manutenção da cultura e a geração de renda das populações do entorno de Unidades de Conservação. No ecoturismo a natureza é o atrativo de consumo e sua prática é norteada pela ética da sustentabilidade que internaliza a natureza como patrimônio natural e cultural. As variáveis adotadas foram norteadas pelos estudos de Beni (2002) e Bóullon (2002), fundamentadas nas dimensões de sustentabilidade. Como instrumental, utilizou-se de fontes bibliográficas e documentais, entrevistas, visitas à Serra de Itabaiana com georreferenciamento de pontos ecoturísticos e registros fotográficos. O conjunto natural que se constitui a Serra de Itabaiana, cuja elevação de 669 m destaca-se na paisagem rebaixada de seu entorno, foi tomado como uma macropaisagem, subdividida em quatro unidades potenciais para o ecoturismo: o topo, a vertente Oeste, a vertente Este e os vales. Sua morfologia apresenta uma vertente abrupta e rochosa à Oeste e outra com decalagem mais suave à Este. Esta vertente é coberta por campos rupestres, cerrados, restinga e mata atlântica, por onde correm, envoltos pela mata de galeria, quatro nascentes com leitos encachoeirados e pequenas bacias de acumulação que formam piscinas naturais e conformam uma diversidade de ecossistemas de grande valor, justificando restrições ao uso. Outro aspecto relevante identificado consiste na incorporação de vários elementos da Serra na cultura sergipana através de histórias e lendas, o que a torna um lugar especial e potencial para o ecoturismo. Quanto às perspectivas de abertura da Serra de Itabaiana ao uso do ecoturismo, as entrevistas realizadas junto a proprietários de terra, moradores do entorno, agências de turismo, guias e órgãos municipais, estaduais e ao IBAMA - Instituto Brasileiro do Meio Ambiente e de Recursos Naturais Renováveis, balizaram nosso entendimento de que o uso ecoturístico apresenta-se como alternativa possível, desde que se proceda uma mudança na tipologia da Unidade de Conservação, de Estação Ecológica para outro tipo compatível. Embora já tenha um estudo em andamento no IBAMA, amparado pela Lei nº 9.985/2000 que instituiu o Sistema Nacional de Unidades de Conservação (SNUC), e incentiva o ecoturismo em Unidades de Conservação e no seu entorno, como alternativa de desenvolvimento, a análise retrospectiva do processo demonstra carência de envolvimento e compromisso, em vários níveis, dos atores sociais e institucionais envolvidos com a preservação do patrimônio natural e cultural que se constitui a Serra de Itabaiana.

Master of Science / Department of Biology / Martha E. Mather / Understanding the empirical relationships between biotic diversity and components of the environment is crucial for effective research and management, particularly in highly disturbed watersheds. The Smoky Hill River is a semi-arid prairie stream with a historic native fish community that is adapted to the extreme and highly variable climatic and hydrological conditions characteristic of the Great Plains streams. Following a literature review on environmental variables, diversity responses, and analysis methods, I evaluated the importance of land use, flow, discontinuities (dams, confluences), and stream type (mainstem-tributary) variables in explaining fish richness using AICc model selection with multiple linear, Poisson and negative-binomial regressions. I then compared these results from 48 sites across three watershed regions to those from a long-term monitoring dataset (ST) using the same candidate variables. Finally, I examined phylogenetic patterns of the fish community using ordination analyses. Patterns and drivers of biodiversity differed with watershed region, land use, stream type, and flow. Fish species richness in the Smoky Hill watershed was negatively correlated with percent developed land in the Lower region of the watershed, but positively correlated with percent herbaceous grassland, the reference prairie condition, in the Upper region of the watershed. Summer mean flow was consistently and positively related to species richness in the Middle and Upper regions of the watershed where flow was limited. In the Lower region of the watershed, species richness was higher in the more flow-moderate tributaries relative to high-flow mainstem sites. In the Middle and Upper flow-limited regions, species richness was lower in the low-flow tributaries than main stem sites. Families of fish species were also related to region and stream type (mainstem vs. tributary). A comparison of two databases showed how different goals, questions, and methods result in different insights, emphasizing the need for establishing a priori goals before sampling.
