The transport sector is seen as particularly problematic when concerns about climate change and dependency on fossil energy are discussed. Because of this, bioenergy is strongly promoted for use in the transport sector, both on a European level and nationally in Sweden. Even though bioenergy is considered one of the key solutions, it is generally agreed that both supply- and demand-side measures will be needed to achieve a change to a more sustainable transport system. One of the reasons for this is the limited availability of biomass, especially agricultural feedstocks competing with food or feed production. Woody biomass, however more abundant, is also exposed to tough competition from other sectors. In this thesis, the role of biogas as a vehicle fuel in a future sustainable transport system is discussed together with the prerequisites needed to realise such a transport system. Biogas is a biofuel that could be produced in several different ways: by anaerobic digestion, which is a first-generation production route, by gasification, which is a second-generation process, and by catalytic reduction of carbon dioxide, a third-generation technology. The main focus in this thesis is on biogas produced by anaerobic digestion and the results show that there is a significant potential for an increase compared to today’s production. Biogas from anaerobic digestion, however, will only be able to cover a minor part of the demand in the Swedish transport sector. Considering biogas of the second and third generations, the potential for production is more uncertain in a mid-term future, mainly due to competition for feedstock, the possibility to produce other fuels by these processes, and the present immaturity of the technology. The limited potential for replacing fossil vehicle fuels, either by biogas or other renewable fuels, clearly shows the need for demand-side measures in the transport system as well. This thesis shows the importance of technical and non-technical means to decrease the demand for transport and to make the transport as efficient as possible. The results show that both energy-efficient vehicles and behavioural and infrastructural changes will be required. Policies and economic incentives set by governments and decision-making bodies have a prominent role to play, in order to bring about a shift to a more sustainable transport system, however, measures taken on individual level will also have a great impact to contribute to a more sustainable transport system. / <p>QC 20121116</p>

Ce mémoire porte sur l’insertion des Haïtiens de seconde génération sur le marché de l’emploi. L’insertion professionnelle est la condition principale permettant une intégration sociale. En effet, avoir un emploi a des répercussions au niveau économique, social et psychologique. Les écrits ont montré que les jeunes et particulièrement ceux faisant partie d’une minorité visible ont plus de difficulté à s’insérer sur le marché du travail. C’est dans cette optique que nous nous sommes penchés sur la condition des Haïtiens de deuxième génération. La littérature fait état des multiples difficultés sociales et économiques auxquelles est confrontée cette tranche de la population. Nous nous sommes donc intéressés aux caractéristiques de l’insertion professionnelle des ces Haïtiens de seconde génération. Nous avions comme objectif général d’analyser la trajectoire d’insertion de cette population sur le marché du travail. Notre démarche de type qualitatif s’est basée sur une série d’entrevues réalisées à l’hiver 2010 avec des hommes et des femmes Québécois d’origine haïtienne. Les thèmes abordés durant ces entrevues nous ont menés à des résultats différents de ceux recensés dans la littérature académique portant sur les Haïtiens de deuxième génération. En effet, nous avons rencontré des hommes et des femmes qui ont rencontré certains obstacles et qui continuent à faire face à des difficultés en lien avec leur vécu comme individu ayant une origine ethnique différente de celle de la majorité. Ces difficultés se manifestent également dans leur insertion en emploi. Cependant, cela n’a pas empêché ces enfants d’immigrants haïtiens de surmonter les obstacles et réussir leur intégration aux plans professionnel, économique et social. / This thesis focuses on the integration of second-generation Haitians on the job market. Integration on the job market is the main condition for social integration as being employed has impacts at the economical, social and psychological levels. The literature has shown that young people, particularly those belonging to visible minorities have more difficulty in entering the labor market. With this in mind, we examined the status of second-generation Haitians. The literature reports of multiple social and economic difficulties faced by this segment of the population. We are therefore interested in the characteristics of the experience of these second-generation Haitians in the workforce. Our main objective was to analyze the general trajectory of insertion of this population in the labor market. Our qualitative approach was based on a series of interviews conducted in the winter of 2010 with men and women of Haitian origin. Topics discussed during these interviews led to different results from those identified in the academic literature on second-generation Haitians. Indeed, we have met men and women who have encountered some obstacles and continue to face difficulties related to their experiences as individuals with an ethnic background different from that of the majority. These difficulties manifest themselves in their experience on the labor market. However, this has not prevented these children of Haitian immigrants to overcome obstacles and succeed in their integration at the professional, economic and social levels.

Cette thèse se concentre sur le développement d'une méthode précise et efficace pour la simulation des grandes échelles (LES) des écoulements turbulents. Une approche de la LES basée sur la méthode variationnelle multi-échelles (VMS) est considérée. La VMS applique aux équations de la dynamique des fluides une séparation d'échelles a priori sans recours à des hypothèses sur les conditions aux limites ou sur l'uniformité du maillage. Afin d'assurer effectivement une séparation d'échelles dans l'espace des nombres d'onde associé, nous choisissons d'utiliser les ondelettes de deuxième génération (SGW), une base polynomiale qui présente des propriétés de localisation spatiale-fréquence optimales. A partir de la séparation d'échelles ainsi réalisée, l'action du modèle sous-maille est limitée à un intervalle de nombres d'onde proche de la coupure spectrale. Cette approche VMS-LES basée sur les ondelettes est désignée par WAVVMS-LES. Elle est incorporée dans un solveur d'ordre élevé pour la simulation des écoulements incompressibles sur la base d'une méthode de Galerkin discontinue (DG-FEM) stabilisée pour la pression. La méthode est évaluée par réalisation de LES sur des maillages fortement sous-résolus pour le cas test du tourbillon de Taylor-Green 3D à deux nombres de Reynolds différents. / This thesis focuses on the development of an accurate and efficient method for performing Large-Eddy Simulation (LES) of turbulent flows. An LES approach based upon the Variational Multiscale (VMS) method is considered. VMS produces an a priori scale-separation of the governing equations, in a manner which makes no assumptions on the boundary conditions and mesh uniformity. In order to ensure that scale-separation in wavenumber is achieved, we have chosen to make use of the Second Generation Wavelets (SGW), a polynomial basis which exhibits optimal space-frequency localisation properties. Once scale-separation has been achieved, the action of the subgrid model is restricted to the wavenumber band closest to the cutoff. We call this approach wavelet-based VMS-LES (WAV-VMS-LES). This approach has been incorporated within the framework of a high-order incompressible flow solver based upon pressure-stabilised discontinuous Galerkin FEM (DG-FEM). The method has been assessed by performing highly under-resolved LES upon the 3D Taylor-Green Vortex test case at two different Reynolds numbers.

Orientador: Mario Luiz Teixeira de Moraes / Resumo: O êxito dos programas de melhoramento florestal requer que a predição do progresso genético seja proporcional ao progresso genético real. Para isso, é possível unir a genética quantitativa com ferramentas moleculares, que permitem estimar parâmetros com maior acuidade para seleção. O objetivo foi verificar a diversidade genética, o sistema de reprodução e as relações de parentesco em populações de polinização aberta de Eucalyptus urophylla, para selecionar cruzamentos e genitores. Para tanto, foram utilizados dois Pomares de Sementes por Mudas (PSM) e uma amostra de indivíduos adultos em um teste de progênies (PCPN). Para compor um teste de progênies de segunda geração (TP2G) foram coletadas sementes em 23 árvores matrizes em um dos PSM. As populações estão localizadas na Fazenda de Ensino, Pesquisa e Extensão, em Selvíria-MS. Os indivíduos do TP2G (722) e os adultos (467) foram genotipados com 12 marcadores microssatélites (SSR) e os locos avaliados para verificar se são marcadores genéticos. Os caracteres silviculturais foram mensurados nos PSM e no TP2G. Os marcadores SSR formaram um conjunto consistente de marcadores genéticos. A diversidade genética das populações foi elevada e a redução foi pequena entre as gerações. O índice de fixação foi significativo para todas as populações e maior nos descendentes, a indicar a presença de endogamia. A taxa de cruzamento indicou que a reprodução ocorreu predominantemente por cruzamentos (0,964). Houve cruzamentos entre parentes, co...

For this, it is possible to join the quantitative genetics with molecular tools, which allow to estimate parameters with greater acuity for selection. The main was to verify the genetic diversity, mating system and kinship relationships in open pollinated populations of Eucalyptus urophylla, to select crosses and parents. In order to do, two seedlings seed orchards (SSO) and an adult sample of individuals were used in a progeny test (PCPN). To compose a second generation progenies test (2GPT) seeds were collected in 23 mother trees in one of the SSO. The populations are located in the Fazenda de Ensino, Pesquisa e Extensão, in Selvíria-MS. The individuals from 2GTP (722) and adults (467) were genotyped with 12 microsatellite markers (SSR) and the loci evaluated for genetic markers. Silvicultural traits were measured in the SSO and 2GPT. SSR markers formed a consistent set of genetic markers. The genetic diversity of the populations was high and the reduction was small between generations. The fixation index was significant for all populations and higher in the offspring, indicating the presence of inbreeding. The multilocus estimate of outcrossing rate indicated that reproduction occurred predominantly by crosses (0.964). There were crosses between relatives, crosses correlated and self-fertilization. As a result, inbreeding in the progenies wa... (Complete abstract click electronic access below) / Doutor

Le renouveau des biocarburants pourrait être aussi celui de l’industrie chimique de la pâte àpapier, en diversifiant l’éventail des produits fabriqués à partir de bois. Cette étude porte surl’intégration d’une extraction des hémicelluloses du bois au procédé Kraft dans le cadre d’une coproductionde fibres cellulosiques et de bioéthanol.Le travail expérimental de cette étude balaie l’ensemble du procédé depuis l’extraction de plus dela moitié des hémicelluloses de bois de résineux, par autohydrolyse ou par hydrolyse à l’acidedilué, jusqu’à la production de fibres cellulosiques blanchies et d’éthanol obtenu par la fermentationdes hydrolysats.Les pâtes de bois préhydrolysé se sont distinguées par de très bonnes aptitudes à ladélignification lors de la cuisson Kraft et lors du blanchiment à l’oxygène. Une analyse desconstituants des pâtes de bois préhydrolysé a permis de comprendre pourquoi la préhydrolyseconduit à une diminution du rendement de cuisson (perte de lignine et de la totalité deshémicelluloses dont les xylanes). L’analyse des lignines de pâtes écrues de bois préhydrolysé apermis d’émettre une hypothèse quant à l’excellente aptitude de ces pâtes à la délignification lorsdu blanchiment à l’oxygène.En définitive, l’intégration d’une extraction des hémicelluloses à une usine Kraft telle qu’elle estproposée par cette étude permet d’obtenir à partir de 100 kg de bois de résineux, 27 à 36kilogrammes de fibres cellulosiques blanchies et jusqu’à 6 litres de bioéthanol. Ces fibrescellulosiques blanchies présentent des caractéristiques attrayantes pour la production de cellulose àusage chimique ou de nanocristaux de cellulose. / Biofuel revival could be a great opportunity for the chemical pulp industry to widen the range ofits products made from wood. This thesis deals with the integration of a softwood hemicelluloseextraction step prior to the Kraft pulping process in order to produce both cellulose fibres andbioethanol.In this study the experimental work covers the entirety of the process: from the extraction ofmore than half of the hemicelluloses from wood either by autohydrolysis or dilute acid hydrolysis tothe production of bleached cellulosic fibres as well as ethanol from fermentated wood hydrolyzates.Prehydrolyzed wood and their subsequent pulps stood out by their excellent delignification abilityduring Kraft cooking and oxygen bleaching. Quantitative analysis of the main constituants of thepulps showed why prehydrolysis leads to decreased Kraft pulp yields (extra lignin loss andhemicelluloses loss including xylans). A range of hypotheses to explain the good delignificationability of prehydrolyzed wood Kraft pulps during oxygen bleaching was narrowed to one by Kraftlignin analysis.The overall results of the hemicellulose extraction prior to Kraft pulping as it has been defined inthis study showed that from 100 kg of softwood, 27 to 36 kg of bleached cellulosic fibres and 6litres of ethanol could be produced. The bleached cellulosic fibres are of great interest for dissolvingpulp or cellulose nanocrystals production.
