abstract: To date, the production of algal biofuels is not economically sustainable due to the cost of production and the low cost of conventional fuels. As a result, interest has been shifting to high value products in the algae community to make up for the low economic potential of algal biofuels. The economic potential of high-value products does not however, eliminate the need to consider the environmental impacts. The majority of the environmental impacts associated with algal biofuels overlap with algal bioproducts in general (high-energy dewatering) due to the similarities in their production pathways. Selecting appropriate product sets is a critical step in the commercialization of algal biorefineries. This thesis evaluates the potential of algae multiproduct biorefineries for the production of fuel and high-value products to be economically self-sufficient and still contribute to climate change mandates laid out by the government via the Energy Independence and Security Act (EISA) of 2007. This research demonstrates: 1) The environmental impacts of algal omega-3 fatty acid production can be lower than conventional omega-3 fatty acid production, depending on the dewatering strategy. 2) The production of high-value products can support biofuels with both products being sold at prices comparable to 2016 prices. 3) There is a tradeoff between revenue and fuel production 4) There is a tradeoff between the net energy ratio of the algal biorefinery and the economic viability due to the lower fuel production in a multi-product model that produces high-value products and diesel vs. the lower economic potential from a multi-product model that just produces diesel. This work represents the first efforts to use life cycle assessment and techno-economic analysis to assess the economic and environmental sustainability of an existing pilot-scale biorefinery tasked with the production of high-value products and biofuels. This thesis also identifies improvements for multiproduct algal biorefineries that will achieve environmentally sustainable biofuel and products while maintaining economic viability. / Dissertation/Thesis / Doctoral Dissertation Civil and Environmental Engineering 2016

abstract: Concentrating Solar Power (CSP) plant technology can produce reliable and dispatchable electric power from an intermittent solar resource. Recent advances in thermochemical energy storage (TCES) can offer further improvements to increase off-sun operating hours, improve system efficiency, and the reduce cost of delivered electricity. This work describes a 111.7 MWe CSP plant with TCES using a mixed ionic-electronic conducting metal oxide, CAM28, as both the heat transfer and thermal energy storage media. Turbine inlet temperatures reach 1200 °C in the combined cycle power block. A techno-economic model of the CSP system is developed to evaluate design considerations to meet targets for low-cost and renewable power with 6-14 hours of dispatchable storage for off-sun power generation. Hourly solar insolation data is used for Barstow, California, USA. Baseline design parameters include a 6-hour storage capacity and a 1.8 solar multiple. Sensitivity analyses are performed to evaluate the effect of engineering parameters on total installed cost, generation capacity, and levelized cost of electricity (LCOE). Calculated results indicate a full-scale 111.7 MWe system at $274 million in installed cost can generate 507 GWh per year at a levelized cost of $0.071 per kWh. Expected improvements to design, performance, and costs illustrate options to reduce energy costs to less than $0.06 per kWh. / Dissertation/Thesis / Masters Thesis Civil, Environmental and Sustainable Engineering 2017

Tanto para a Geografia quanto para a Arqueologia é fundamental o estudo das técnicas, pois é através delas que o homem pode medir seu nível cultural. Tentar entender e compreender que essas técnicas são a peça chave para saber quais eram os hábitos e costumes dos povos pré-históricos, pois através dessas técnicas é que podemos saber quais eram seu modo de vida e sua relação com o espaço ocupado. Com isso podemos ver que numa análise mais abrangente através do conhecimento de técnicas, podemos estar descrevendo os costumes dos povos que habitaram determinada região. Neste aspecto, o projeto tem por objetivo analisar o material arqueológico encontrado durante as escavações, procurando identificar, através de um sítio definido, que servirá como parâmetro, quais as técnicas utilizadas pelos povos pré-históricos que habitaram a região, bem como compreender e identificar qual a origem desses povos, e a que grupos pertenciam, bem como a forma pela qual eles se relacionavam com o meio natural para a construção do espaço geográfico no qual habitaram no passado. Identificando esses povos não apenas estaremos descobrindo uma parte de nossa própria história regional, bem como avançando na compreensão da evolução do homem enquanto agente transformador do espaço em que habitava e interagia. / This work is a contribution to archaeological research that can provide the understanding about the formation of geographical space and their transformations. Both for the Geography and the Archeology the study of techniques is fundamental, for it is through them that man can measure their cultural level. Trying to understand and realize that these techniques are the key to what the habits and customs of prehistoric people were, because through these techniques is that we can know what were their way of life and their relation to space. With this we can see that in a more comprehensive analysis of their techniques we can describe the customs of peoples who inhabited a region. Here, the project aims to analyze the material found during the archaeological excavations, seeking to identify, through a established site to serve as a parameter to which techniques were used by prehistoric peoples who inhabited the region, and understand and identify which origin of these peoples and groups that belonged, and the way in which they interact to the natural environment for the construction of the geographical area in which they inhabited in the past. By identifying these people, we will not only discover a part of our regional history, as well as advancing the understanding of the evolution of man as an agent of transformation of the space in which they lived and interacted.

Partimos do pressuposto de que o processo de modernização territorial de Rondonópolis, por meio da instalação de um novo sistema de objetos e de ações, característico do período técnico-científico-informacional, provocou a refuncionalização deste subespaço, tornando-o um centro funcional, instrumentalizado e apto a responder eficazmente às demandas dos agentes hegemônicos do capitalismo mundializado, aqui retratados pelo agronegócio da soja. Assim, enquanto essa pequena minoria usa de forma corporativa o território, interpretando-o enquanto recurso, usufruindo os novos fatores da modernidade em sua plenitude, todo o restante da sociedade local só faz uso de algumas parcelas desse mesmo território, o território entendido enquanto abrigo, e do novo sistema técnico e organizacional advindo da modernização. Assim, esse processo nos revela o uso desigual do tempo e do espaço em Rondonópolis, resultando na fragmentação do território e na manutenção e/ou agravamento de desigualdades sócio-territoriais herdadas / Abstract: This study aimed for understanding of the new uses of territory of Rondonópolis - MT, resulting from the internalization process of the techno-scientific Milieu, in the context of expansion of soya agribusiness to areas of cerrado from brazilian central west, particularly in state of Mato Grosso. We start from the presupposition that the territorial modernization of Rondonópolis, through the installation of a new system of objects and actions, characteristic of the techno-scientific period, caused the re-functionalization of this subspace, making it a functional center, instrumental and able to respond effectively to the demands of the hegemonic agents of globalized capitalism, here retracted by soya agribusiness. This way, while this small minority uses of corporate the territory, interpreting it as a resource, enjoying the new factors of modernity in its fullness, the rest of local society just uses some parts of this same territory, the territory as a shelter, and the new technical and organizational system from the modernization. This way, this process reveals to us the uneven use of time and space in Rondonópolis, resulting in fragmentation of the territory and the maintenance and/or aggravation of social territorial inequalities inherited / Doutor

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / The new world order, called Technocracy (XAVIER, 2009) indicates that the school can not ignore the reality in which it operates, it is constituent of a communications transformation process promoted by new technologies, but incidents also in ways of working , to decide, to think. Given this and new pedagogical framework, we aim therefore investigate the constitution of the discursive ethos anchored in three aspects of autobiographical narratives, namely the report of the teaching pedagogical praxis - front postmodern contextual influence and adequacy challenge to current educational environment in the clinical interview (MAIA-VASCONCELOS, 2005), the redefinition of the self-image of the teachers vie ârÃcitâ and narrative self-receptivity. The research corpus is composed of 20 techno autobiographical narratives. The research rhetoric composition has a multidisciplinary theoretical approach, which includes studies in the areas of education, sociology, philosophy and linguistics, under different axes, namely: the studies of autobiographical narratives, as a research method, data analysis and formation of narrative (BOLÃVAR, DOMINGO e FERNÃNDEZ, 2001; DOMINICÃ, 2007; PASSEGI, 2011; BERTAUX, 2010; BRUNER, 2006; JOSSO, 2009; LEJEUNE, [2008] 2014; MAIA-VASCONCELOS, 2003; PINEAU e LE GRAND, 2012; BAKHTHIN, 2003); studies of the self-image in speech (AMOSSY, 2005), the biographical embodiment (JOSSO, 2007, 2008, 2012); the sensitive body (BOIS e RUGIRA, 2006; HUMPICH, 2008); the discursive ethos (MAINGUENEAU, 1995, 2006, 2011); technological habitus (BOURDIEU, 2002, 2003, 2004; BOURDIEU e CHARTIER, 2012; ALBUQUERQUE, 2005); the relationship between the foreshadowing, figuration and refiguration narrative (RICOEUR, 1994, 1995, 1997, 2000a, 2000b, 2011); the approaches to the post-modern educational context and the new pedagogy (UNESCO, 2005, 2008; DEMO, 2009; FINO, 2008; LIBÃNEO, 1998; CAHRLOT, 2008; KENSKY, 2012, 2013); the relationship between time and reflexivity (GIDDENS, 2002); the postmodern historical context (BALMAN, 2001). The analysis has revealed that teachers show be aware that, in addition to expertise in their area, must show, in particular, digital skills (CARENZIO, 2012). Therefore, the survey results allow us to say that the teachers ethos emerges in techno autobiographical narrative in the unveiling of a discursive game in which the narrative setting signifies that, interwoven by a dialectical relationship, in the same proportion that the pedagogical praxis report influences in the reframing and the constitution of the image itself, it is also reinterpreted and made from that image of themself new meaning. In this perspective, the driving strength that propels the subject to this constant reinterpretation of the image itself is grounded in the desire to break paradigms and improve on the use of digital technologies. Thus, the formation of technological habitus depends less generational factor and more social capital, cultural and economic teacher. So whether or not presenting a geek ethos, the postmodern teacher who took a praxis mediated by pedagogical digital artifacts is, above all, curious and this insignia is revealed in the desire to learn and improve themselves constantly. / A nova ordem mundial, denominada de Tecnocracia (XAVIER, 2009) indica que a escola nÃo pode ignorar a realidade na qual està inserida, vez que à constituinte de um processo de transformaÃÃo das comunicaÃÃes promovido pelas novas tecnologias, mas incidentes tambÃm nos modos de trabalhar, de decidir, de pensar. Diante desse novo quadro pedagÃgico, objetivamos, pois, investigar a constituiÃÃo do ethos discursivo ancorado em trÃs vertentes de narrativas tecnoautobiogrÃficas, a saber, o relato da prÃxis pedagÃgica docente - frente a influÃncia contextual pÃs-moderna e o desafio de adequaÃÃo à atual conjuntura educacional na entrevista clÃnica (MAIA-VASCONCELOS, 2005), a ressignificaÃÃo da imagem de si no rÃcit de vie dos professores e a autorreceptividade narrativa. O corpus da pesquisa à composto de 20 narrativas tecnoautobiogrÃficas e a composiÃÃo retÃrica da pesquisa tem um aporte teÃrico multidisciplinar, que compreende estudos nas Ãreas da educaÃÃo, da sociologia, filosofia e da LinguÃstica, sob diferentes eixos, a saber, os estudos das narrativas autobiogrÃficas, enquanto mÃtodo de pesquisa, anÃlise dos dados e narrativa de formaÃÃo (BOLÃVAR, DOMINGO e FERNÃNDEZ, 2001; DOMINICÃ, 2007; PASSEGGI, 2011; BERTAUX, 2010; BRUNER, 2006; JOSSO, 2009; LEJEUNE, [2008] 2014; MAIA-VASCONCELOS, 2003; PINEAU e LE GRAND, 2012; BAKHTHIN, 2003); os estudos da imagem de si no discurso (AMOSSY, 2005), a corporificaÃÃo biogrÃfica (JOSSO, 2007, 2008, 2012); o corpo sensÃvel (BOIS e RUGIRA, 2006; HUMPICH, 2008) o ethos discursivo (MAINGUENEAU, 1995, 2006, 2011); o habitus tecnolÃgico (BOURDIEU, 2002, 2003, 2004; ALBUQUERQUE, 2005); a relaÃÃo entre a prefiguraÃÃo, a figuraÃÃo e a refiguraÃÃo da narrativa (RICOEUR, 1994, 1995, 1997, 2000a, 2000b, 2011); as abordagens sobre o contexto educacional pÃs-moderno e a nova pedagogia (UNESCO, 2005, 2008; DEMO, 2009; FINO, 2008; LIBÃNEO, 1998; CHARLOT, 2008; KENSKY, 2012, 2013); a relaÃÃo entre tempo e reflexividade (GIDDENS, 2002); o contexto histÃrico pÃs-moderno (BALMAN, 2001). A anÃlise nos revelou que os professores demonstram ter consciÃncia de que alÃm da competÃncia na sua Ãrea de atuaÃÃo, deve apresentar, sobretudo, habilidades digitais (CARENZIO, 2012). Portanto, os resultados da pesquisa nos permitem afirmar que o ethos docente emerge na narrativa tecnoautobiogrÃfica no desvelar de um jogo discursivo no qual a configuraÃÃo narrativa atesta que, imbricados por uma relaÃÃo dialÃtica, na mesma proporÃÃo que o relato da prÃxis pedagÃgica corrobora para ressignificaÃÃo e constituiÃÃo da imagem de si, ele à tambÃm ressignificado e constituÃdo a partir dessa imagem de si ressignificada. Nessa perspectiva, a forÃa motriz, que impele o sujeito à essa constante ressignificaÃÃo da imagem de si, se ancora no desejo de quebrar paradigmas e aperfeiÃoar-se no uso das tecnologias digitais. Sendo assim, a formaÃÃo do habitus tecnolÃgico depende menos do fator geracional e mais do capital social, cultural e econÃmico do professor. Portanto, quer apresentando ou nÃo um ethos geek, o professor pÃs-moderno que assumiu uma prÃxis mediada por artefatos pedagÃgicos digitais Ã, sobretudo, um curioso e essa insÃgnia se revela no desejo de aprender e de aperfeiÃoar-se incessantemente.

Desde seu surgimento, a fotografia e seu caráter híbrido, delineado pela conjunção entre ciência e arte, foi mais assimilada como ferramenta tecnológica a serviço desses conhecimentos, e não como um fenômeno originariamente capaz de questionar seus lugares dentro do pensamento ocidental; este, reflexo de um determinado projeto moderno de investigação e vivência. Tomandose como eixo de análise a pontuação de alguns aspectos de sua trajetória tecnológica e de sua inserção social, o presente estudo objetiva examinar bases filosóficas para a compreensão da fotografia em sua configuração digital contemporânea, apoiando-se em modelos interpretativos propostos por Roland Barthes e Vilém Flusser, mas também buscando aporte teórico no pensamento de Martin Heidegger. Entende-se que o universo digital, sobretudo se observados os processos de hibridação e as interconexões facilitadas por certas especificidades do numérico, estabelece a ambiência necessária para que a fotografia e seus desdobramentos, as tecnoimagens, possam ser usufruídas dentro de suas perspectivas mais originais e elementares. / Since its beginning, the photography and its hybrid nature, drawn by the conjunction of science and art, was treated more as a technological tool for service to those knowledges, and not as a phenomenon originally able to question their place in Western thought, this one understood as a reflexion of a particular modern project of research and experience. Taking as a point of analysis some aspects of their technological trajectory and their social integration, this study aims to examine philosophical basis for the understanding of photography in its digital contemporary setting, using the interpretative models proposed by Roland Barthes and Vilém Flusser, but also looking for support in the thought of Martin Heidegger. It is understood that the digital universe, especially when observing the processes of hybridization and the interconnections facilitated by certain characteristics of numeric, sets the ambience necessary for the photograph and its consequences, the techno-images, to be enjoyed within their prospects more original and elementary.

Solar heat pump systems (SHPs) are systems that combine solar energy and heat pumps. SHPs have been investigated for several decades and have been proven to increase the share of renewable energy and reduce electric energy demand in residential heating applications. Many solar thermal heat pump systems have become market-available in recent years; however these systems are still not widely employed in the residential sector. This is due mainly to the high initial costs (investment and installation costs) of solar thermal heat pump systems, which limits their cost-effectiveness. Enhancing cost-effectiveness of solar thermal heat pump systems is necessary for a more effective and broader market penetration. In this thesis, solar thermal and photovoltaic systems combined with heat pumps for heating applications are treated. The overall aims of the thesis are to: 1) investigate techno-economics of SHPs and 2) investigate possible solutions for improving system performance of a reference solar thermal and heat pump system for residential heating applications. In the first part of the thesis, the influence of climatic boundary conditions on economic performance of SHPs has been investigated by means of: a) an economic comparison of SHPs found in the relevant literature and b) system simulations of the reference solar thermal heat pump system. In the second part of the thesis, potential solutions for improving system performance of the reference solar thermal heat pump system with limited change in system’ costs are investigated. A systematic approach was used for investigating cost-effectiveness of the system improvements in the reference system. Based on results of the cost-effectiveness analysis, some of the investigated system improvements were chosen for being included in the design of a novel solar thermal and air source heat pump system concept. The novel system was designed for a house standard with relatively high operating temperatures (55°C/45°C) in the space heating distribution system and for high space heating demand (123 kWh/m2·year). Finally, the thesis ends with a cost-effectiveness analysis of the novel system. / <p>QC 20170918</p> / MacSheep / iNSPiRe

Biofuels have been identified as one of several GHG emission strategies to reduce the use of fossil fuels in the transport sector. Fast pyrolysis of biomass is one approach to producing second generation biofuels. The bio-oil product of fast pyrolysis can be upgraded into essential gasoline and diesel range products with conventional refinery technologies. Thus, it is important to assess their techno- economic and environmental performance at an early stage prior to commercialisation. This research was conducted with the goal of evaluating and comparing the techno-economic and environmental viability of the production of biofuels from fast pyrolysis of biomass and upgrading of bio-oil via two refinery technologies, viz. hydroprocessing and zeolite cracking. In order to achieve this aim, process models of fast pyrolysis of biomass and bio-oil upgrading via hydroprocessing and zeolite cracking were developed. The fast pyrolysis model was based on multi-step kinetic models. In addition, lumped kinetic models of the hydrodeoxygenation reactions of bio-oil were implemented. The models were verified against experimental measurements with good prediction and formed the foundation for the development of a 72 t/day fast pyrolysis plant model in Aspen Plus®. Several strategies were proposed for the two pathways to enhance energy efficiency and profitability. All in all, the results revealed that the hydroprocessing route is 16% more efficient than the zeolite cracking pathway. Moreover, the hydroprocessing route resulted in a minimum fuel selling price of 15% lower than that from the zeolite cracking pathway. Sensitivity analysis revealed that the techno-economic and environmental performance of the both pathways depends on several process, economic and environmental parameters. In particular, biofuel yield, operating cost and income tax were identified as the most sensitive techno-economic parameters, while changes in nitrogen feed gas to the pyrolysis reactor and fuel yield had the most environmental impact. It was concluded that hydroprocessing is a more suitable upgrading pathway than zeolite cracking in terms of economic viability, energy efficiency, and GHG emissions per energy content of fuel produced.

À l’heure du plein exercice d’une médecine à la logique technoscientifique, fondée sur les preuves et le factuel, appelée aussi Evidence Based Medicine, reposant sur les principes scientifiques de quantification, de visualisation et d’universalité de la biomédecine ; à l’heure d’une santé désormais définie par la statistique, de la souffrance humaine étalonnée sur le modèle du simple fonctionnement cérébral, l’homme postmoderne se trouve pris dans une hyper-médicalisation de l’existence. Ce présent travail de thèse souhaite rendre compte d’une réalité clinique du soin en milieu gérontologique. La logique de rentabilité obsédante, l’évaluation chiffrée systématisée, leur alliance avec la pulsion de mort et les dérives qui en résultent, tant dans leurs discours que dans leurs mises en actes, ainsi que le défi éthique lancé à la société qu’elles représentent devront être analysées. La seule valeur marchande que le patient peut représenter dans la recherche de rendement et de bénéfice nous pousse à interroger directement le devenir de la subjectivité et à poser inévitablement les questions relatives à l’ontologie, à l’anthropologie d’un sujet vivant la postmodernité et réduit, en tant que patient, à incarner ce qu’Hannah Arendt a nommé l’« Œuvre ». Car en effet : cette postmodernité dont nous sommes contemporains, via le progrès scientifique rejette purement et simplement le manque structural fondateur de tout sujet, pour viser une certaine artificialisation de l’être. Il s’agit alors de démontrer que la psychanalyse peut encore, de par sa méthode et son herméneutique, répondre aux exigences éthiques actuelles. Dès lors, s’engager dans une écoute des signifiants que le malade adresse équivaut à garantir, dans un tel contexte, ce que Michel Foucault appelait « un processus de re-subjectivation » et occasionne la réintroduction d’une « errance éthique minimale » désormais indispensable afin d’éviter toute clôture définitive du sujet malade. In fine accepter de considérer qu’un autre discours subjectif subsiste, même paré des traits de l’erreur a priori, et qu’il ne constitue pas un « néant de savoir au vrai » mais un savoir intuitif cherchant à se constituer du côté du sujet malade selon sa propre logique, atteste que cette éthique psychanalytique est de nature pleinement anthropologique. / When medicine based on a techno-scientific logic is widely practised based upon proofs and facts, this ‘Evidence Based Medicine’ is supported by the scientific principles of quantification, presentation and the universalism of biomedicine. When health is defined by statistics, when human suffering is measured on a simple model of brain function, the postmodern citizen is taken over by a hyper-medicalisation of existence. This thesis seeks to account for a healthcare actuality in geriatric medicine. The obsessive logic of value for money, systematic statistical evaluation and their alliance with the death drive and its consequences in discourse and action, as well as the ethical challenge they pose to the society that they represent require analysis. The sole market value the patient represents in research for return and advantage requires us to examine the issue of the future of subjectivity directly and inevitably to ask questions about the ontology, and anthropology of the living postmodern subject reduced, as a patient to an incarnation of what Hannah Arendt termed ‘work’. Indeed, our contemporary postmodernity, through scientific process rejects purely and simply the fundamental structural lack of each subject, creating a certain artificiality of being. The task then, is to demonstrate that psychoanalysis through its methods and hermeneutics can still respond to contemporary ethical demands. Consequently focusing on listening to the signifiers the patient evokes works to safeguard, in this context, what Michel Foucault termed ‘a re-subjectivation proces’ and offers the opportunity to reintroduce the ‘minimal ethical errance’ currently indispensable in avoiding definitive closure of the ill subject. Finally, we accept the consideration that an alternative subjective discourse remains, even dressed up in errors, and that it does not constitute a ‘negation of truth knowledge’ but an intuitive knowledge created by the ill subject according to their own logic, attesting that these psychoanalytical ethics are clearly anthropological in nature.
