Full textEstrelas de alta massa têm grande impacto na evolução do Universo e o processo de formação destes objetos ainda é um problema em aberto na Astrofísica. Os detalhes das estruturas associadas às regiões mais próximas dos objetos centrais, tais como os discos circunstelares e a morfologia dos jatos próximos à base de lançamento, ainda não foram estudados em detalhe e carecem de evidências observacionais. Esta tese apresenta um estudo da formação de estrelas de alta massa em termos da evolução de glóbulos de alta massa (clumps), selecionados a partir do levantamento ATLASGAL, a partir de observações da molécula do CO na faixa espectral do sub-milimétrico. Enquanto observações \"single-dish\" no sub-milimétrico possibilitam o estudo em larga escala do processo de formação de estrelas de alta massa, observações com maior resolução angular são necessárias para investigar os detalhes das protoestrelas no interior dos glóbulos. Para isso, espectroscopia tri-dimensional no infra-vermelho próximo foi obtida para um grupo de fontes RMS para caracterizar o meio circunstelar de objetos estelares jovens e de alta massa (HMYSOs) em escalas lineares de ~100-1000 UA. A amostra TOP100 oferece uma oportunidade ímpar de analisar um conjunto estatisticamente completo de glóbulos de alta massa em diversas fases evolutivas. Observações realizadas com o radiotelescópio APEX de três transições rotacionais da molécula do CO (CO(4-3), CO(6-5) e CO(7-6)) foram utilizadas para estudar as propriedades do gás morno (~155 K) associado aos glóbulos, e obter as relações entre a emissão do CO e as propriedades físicas dos glóbulos. A luminosidade das diferentes transições do CO foi obtida e sua análise mostrou que a emissão do gás aumenta em função do estágio evolutivo dos glóbulos (de glóbulos com emissão fraca no infravermelho longínquo a regiões HII) e em função da luminosidade bolométrica e massa dos glóbulos. A comparação entre os glóbulos de alta massa presentes na amostra TOP100 com fontes de menor massa observadas nas transições do CO(6-5) e CO(7-6), juntamente com a análise de uma amostra complementar de fontes observadas na transição do CO(10-9) mostrou que a dependência da luminosidade do CO com a luminosidade bolométrica aumenta em função do número quântico J associado à transição do CO. Este estudo também mostrou que as relações entre a luminosidade do CO e dos clumps são dominadas pelas fontes de alta luminosidade presentes na amostra analisada. A análise individual de fontes de baixa e alta luminosidade sugerem que a dependência entreas luminosidades do CO e bolométrica é a mesma em ambos os regimes de luminosidade, embora as luminosidades do CO sejam sistematicamente maiores para os glóbulos de alta massa. Por fim, a análise da emissão do CO em altas-velocidades mostrou que ~85% dos glóbulos presentes na amostra TOP100 apresentam jatos moleculares. A seleção de objetos de alta massa isolados em estágio de acreção ativa é crucial para decidir se ela ocorre através de um disco de acreção e/ou via fusão de YSOs de menor massa. Para isso, observações no infra-vermelho próximo são ideais para se investigar o conteúdo dos glóbulos sub-milimétricos e resolver seus membros individuais. Devido a alta resolução espacial na banda K e a extinção interestelar moderada nesta faixa espectral, um conjunto de oito (8) HMYSOs associados a jatos em H2 em larga-escala foram selecionados para observações espectroscópicas na banda K utilizando o espectrômetro NIFS no Gemini Norte. Todos os objetos investigados com o NIFS apresentam emissão extendida no contínuo, bem como nas linhas espectrais típicas de fontes jovens, tais como o Brackett-gama, transições do H2 e a emissão nas bandas moleculares do CO. A emissão em H2 está associada aos jatos moleculares em escalas de ~100 UA em cinco das oito fontes (63%). A indentificação de jatos moleculares em escalas tão próximas ao objeto central indica que o processo de acreção de massa ainda está ativo nestes objetos. A emissão do Brackett-gama provém do gás ionizado nas regiões mais próximas das fontes centrais ou regiões de choque próximas aos jatos. A espectro-astrometria da linha do Brackett-gama em escalas de sub-píxeis, indica que a emissão do gás ocorre nas cavidades dos jatos moleculares ou delineiam estruturas alinhadas perpendicularmente aos jatos, tais como os discos de acreção. Cinco fontes também apresentam emissão nas bandas do CO (63%), e três HMYSOs apresentam linhas do CO em absorção (38%), indicando que estes objetos apresentam discos de acreção. A massa total do sistema \"disco e protoestrela\" foi determinada a partir do estudo da cinemática das linhas de absorção do CO, detectadas em três objetos. A partir de modelos de rotação Kepleriana, as massas das fontes foram estimadas em 5±3, 8±5 e 30±10 massas solares. Os resultados obtidos a partir da espectroscopia tri-dimensional no infravermelho corroboram a hipótese de que estrelas de alta massa são formadas a partir de acreção por discos, de maneira similar ao observado para estrelas de baixa massa. A comparação entre a morfologia dos jatos moleculares identificados nos campos do NIFS e das correspondentes contrapartidas em escalas maiores indicam que os jatos apresentam diferentes graus de colimação ao longo de suas estruturas, explicadas pela multiplicidade de fontes nas proximidades da base de lançamento dos jatos ou efeitos de precessão no objeto central.

Full textThe sealing of hard jointed rock by grouting involves several complicated mechanical systems. The result is a complex coupled system of hydro- logical and mechanical precesses. In order to determine the higher order effects of the resulting system the fracture deformations must be assessed. This requires a model that mimics the mechanical behaviour of not only fractures under normal load but also the entire rock mass system. This model indicates that there are two dominant regimes involved; a permeation regime and a high pressure regime.
The pressure limit that separates permeation grouting from high pressure grouting can then be found to be closely related to the in situ stress. In the high pressure regime the deformations may be large but very situation-dependent. The principal deformational eigenmodes of some boundary conditions are considered. The analysis indicates that the usage of high pressure grouting can be both benficial to the operation as well as increase the inflow of water to the excavation.

Full textCurrent factories producing plant-based fossil-fuel replacements are neither environmentally friendly nor economically viable because their main product, bio-oil, is burned for heat rather than sold for profit. However, bio-oil is rich in potentially valuable aromatic compounds. In order to valorize bio-oil and improve the economic viability of the factories, we need to understand bio-oil’s composition and the effect of processing parameters—such as plant feedstock and pretreatment method. Unfortunately, bio-oil is a complex lignocellulosic mixture that is difficult to analyze. To fully characterize the hundreds of compounds present, analysis typically requires top-end mass spectrometers and lengthy separations. This cost prohibits many laboratories from pursuing bio-oil research. Then time-consuming separations limit recursive analyses to optimize process parameters. The question takes shape: is it possible to analyze complex lignocellulosic mixtures without lengthy separations or top-end mass spectrometers? To assess the feasibility of rapid, affordable analysis, I set out to develop qualitative and quantitative methods using a quadrupole-time-of-flight (QTOF) mass spectrometer. I hypothesized that (a) ionization dopants could mitigate the need for lengthy separations pre-injection and that (b) tandem mass spectrometry could compensate for the midrange resolving power of the QTOF. To test this hypothesis, I started by analyzing another lignocellulosic biomaterial: autohydrolyzate, the product of hydrothermal pretreatment of biomass feedstocks. I observed that two anionic dopants—hydroxide and chloride—worked exceptionally well for selective analysis of the two major components of a lignocellulosic mixture, lignin- and carbohydrate-derivatives. Tandem mass spectrometry confirmed the game-changing selectivity of the dopants. With these favorable results, I applied the ionization dopants to two case studies. Chloride dopant and tandem mass spectrometry were employed to qualitatively analyze the little understood lignin-carbohydrate complexes found in lignocellulosic mixtures. Hydroxide dopant and tandem mass spectrometry were employed to quantitatively analyze the feasibility of valorizing biooil as a performance-enhancing diesel fuel additive. Both projects offered exciting success that redefined the scope of research possible using a QTOF. I demonstrated that by using ionization dopants and tandem mass spectrometry, it is possible for laboratories with limited means to use a cost-effective QTOF for both qualitative and quantitative analysis of complex lignocellulosic mixtures.
