Lately, car manufacturers have been put to a big challenge to reduce the CO2 emission of their entire fleets. Norms of pollutant emissions limit the ways to achieve the desired CO2 emission goals, as some of the solutions that would lead to lower CO2 emission also lead to higher pollutant emission. Waste Heat Recovery (WHR) could be a good solution to lower the CO2 emission of the Internal Combustion Engine (ICE) without increasing the pollutant emission. In the present thesis different WHR strategies are analysed and the results suggested it would be interesting to further study the Brayton cycle machine. Air Brayton Cycle (ABC) represents a way to recover a part of the heat energy of the ICE exhaust gases and transform it into mechanical energy. Recovered mechanical energy would then be returned to the crankshaft of the ICE, thereby reducing the amount of energy that has to be liberated by combustion of fuel which lowers the fuel consumption and CO2 emission. The study of ABC started with an analysis of the ideal cycle in order to obtain the theoretical maximum of the system. The study continued with an analysis of the semi ideal cycle where all losses are taken into account only by two efficiency coefficients. This analysis showed that for the diesel engine efficiency of the ABC is very low because of the low exhaust gas temperature. For the gasoline engine the cycle could be viable when the ICE is working under steady condition and higher load. These conditions could be fulfilled when the vehicle is driven on the highway. Detailed analysis was aimed at determining the cycle main losses. They were determined to be: pumping losses, losses caused by heat transfer and mechanical losses. Taking into account these main losses along with other direct and indirect losses it was concluded that the cycle is not viable for the types of the WHR machines that were considered in this study. In order for the cycle to be viable some other either existing or new machine type should be tested, that would lower the main losses and offer good isentropic and mechanical efficiency for desired conditions. / Últimamente los fabricantes de automóviles se han puesto el gran reto de reducir la emisión de CO2 en la totalidad de sus flotas. Las nuevas normativas para la reducción de las emisiones contaminantes limitan los medios para lograr los objetivos deseados en la emisión de CO2 porque algunas de las soluciones que llevan a la reducción en la emisión de CO2 también dan lugar a un incremento en la emisión de otros contaminantes. La recuperación de calor residual (WHR) podría ser una buena solución para reducir las emisiones de CO2 del motor de combustión interna (ICE) sin poner en peligro la emisión de contaminantes. En la presente Tesis se analizaron diferentes estrategias de WHR y se concluyó que sería interesante estudiar más a fondo la máquina de ciclo Brayton. El Ciclo Brayton de Aire (ABC) permite recuperar una parte del calor de los gases de escape del ICE y transformar este calor en energía mecánica. La energía mecánica recuperada se devuelve al cigüeñal del ICE, reduciendo de ese modo la cantidad de energía que tiene que ser liberada por la combustión del combustible, lo cual permite reducir el consumo de combustible y las emisiones de CO2. En esta Tesis se estudia el ABC mediante un análisis del ciclo ideal con el fin de obtener el máximo teórico del sistema. El modelo se mejora con un análisis del ciclo semi-ideal donde se tienen en cuenta todas las pérdidas mediante el uso de dos coeficientes generales. Este análisis muestra que para el motor diesel la eficiencia del ciclo ABC es muy baja debido a la baja temperatura del gas de escape. Para el motor de gasolina el ciclo podría ser viable cuando el ICE está trabajando bajo condiciones estacionarias y una carga mayor. Estas condiciones se podrían cumplir cuando el vehículo está circulando en autopista. El análisis detallado de este ciclo tiene como objetivo determinar las pérdidas principales de ciclo. Las pérdidas principales se identificaron como: las pérdidas de bombeo, las pérdidas causadas por la transferencia de calor y las pérdidas mecánicas. Teniendo en cuenta estas pérdidas principales junto con otras pérdidas directas e indirectas, se concluyó que el ciclo no es viable para los tipos de máquinas WHR que fueron considerados en este estudio. Para que el ciclo sea viable se tiene que buscar alguna otra máquina existente o un nuevo tipo de máquina que reduzca las principales pérdidas y ofrezca un buen rendimiento isentrópico y mecánico para las condiciones deseadas. / Últimament els fabricants d'automòbils s'han posat el gran repte de reduir l'emissió de CO2 de la totalitat de les seues flotes. Les noves normatives de reducció de les emissions contaminants limiten els mitjans per assolir els objectius desitjats d'emissió de CO2 perquè algunes de les solucions que porten a la reducció en l'emissió de CO2 també donen lloc a un increment a l'emissió de altres contaminants. La recuperació de calor residual (WHR) podria ser una bona solució per reduir les emissions de CO2 del motor de combustió interna (ICE) sense posar en perill l'emissió de contaminants. En la present Tesi s'han analitzat diferents estratègies WHR i es va concloure que seria interessant estudiar més a fons el cicle Brayton. El Cicle Brayton d'Aire (ABC) representa una manera de recuperar una part de la calor dels gasos d'escapament de l'ICE i transformar calor a l'energia mecànica. L'energia mecànica recuperada es retorna al cigonyal de l'ICE reduint d'aquesta manera la quantitat d'energia que ha de ser alliberada per la combustió del combustible permitint la reducció del consum de combustible i les emissions de CO2. En aquesta Tesi s'ha començat estudiant un ABC amb una anàlisi del cicle ideal per tal d'obtenir el màxim teòric del sistema. Este model es millora amb una anàlisi del cicle semiideal on es tenen en compte totes les pèrdues amb tan sols dos coeficients d'eficiència. Aquesta anàlisi va mostrar que per al motor dièsel l'eficiència del cicle ABC és molt baixa a causa de la baixa temperatura del gas d'escapament. Per al motor de gasolina el cicle podria ser viable quan l'ICE està treballant sota condicions estacionàries i una càrrega més gran. Aquestes condicions es podrien complir quan el vehicle està circulant en autopista. L'anàlisi detallada del cicle va tenir com a objectiu determinar les pèrdues principals de cicle. Les pèrdues principals es van identificar com: les pèrdues de bombament, les pèrdues causades per la transferència de calor i les pèrdues mecàniques. Tenint en compte aquestes pèrdues principals juntament amb altres pèrdues directes i indirectes, es va concloure que el cicle no és viable per als tipus de màquines WHR que van ser considerats en aquest estudi. Perquè el cicle puga ser viable s'ha de buscar alguna altra màquina existent o un nou tipus de màquina que puga reduir les principals pèrdues i puga oferir un bon rendiment isentròpic i mecànic per a les condicions desitjades. / Kleut, P.

Why do we laugh at eight-year-old Butters Stotch when he sings about sodomy in South Park? How does the dominant audience understand Michael Scott to be heterosexual following his announcement that he would have sex with a male employee in the American version of The Office? What are the implications of laughing at Bobby Hill when his father expresses embarrassment over Bobby’s plus size modeling career in King of the Hill? I argue that the above characters are versions of the disruptive male character type common in sitcom satires. The sitcom satire is a hybrid genre that follows the sitcom format and contains satirical content. Using tools from queer theory and cultural studies, this thesis examines how particular examples of disruptive characters function in sitcom satires to reinforce cultural codes regarding gender and sexuality. In the first chapter, I suggest that when the male character disrupts normative gender and sexuality the audience laughs at the surprise and incongruity. I argue that the key feature of this character type is that he consistently disrupts cultural codes in ways that would normally mark him as homosexual yet he is not read as a gay character in the shows examined. I suggest that he is queer insofar as he does not fit neatly into the heterosexual/homosexual binary. Following this, in the second chapter, I explain how techniques used in the narrative; such as other characters' reactions, awkward silences, music selection, and scene changes, provide commentary on the disruption. I argue that characters that disrupt expectations of nonnative gender presentation and heterosexuality create anxiety for a dominant audience; the narrative commentary acknowledges that anxiety. Recognizing a character's disruption of cultural codes allows the dominant audience to relieve the anxiety and to reconcile the character's disruption with his heteronormative identity. Finally, in the third chapter I argue that the disruptive character often displays shame or pride in unexpected circumstances and is represented as ignorant I argue that by comparing normative behavior with disruptive or ignorant behavior, the narratives create the preferred or dominant meaning of the desirability of normative behavior. I conclude that the process of disruption, recuperation, and reinforcement reveals two perspectives. First, if disruptions confirm the desirability of the codes they attempt to subvert, then resisting these codes is difficult. Second. disruptions can reveal the construction of these codes; if these cultural codes were as natural as we are to believe, then our culture would not need to work as diligently to uphold them.

A recuperação ambiental de áreas exploradas pela mineração de areia na região do Vale do Paraíba, Estado de São Paulo, constitui anseio popular, obrigação constitucional e fator de diferenciação dentro da mais moderna visão empresarial. Este trabalho estuda a aplicação de turfa como um melhorador de solos na etapa final do processo de recuperação destas áreas: o restabelecimento da vegetação nativa. O interesse surgiu da experiência de trabalho do autor com pesquisa mineral e tecnológica desta substância, além da observação e acompanhamento de alguns projetos de revegetação nestas áreas, tidas como ambientalmente sensíveis e onde os solos apresentam-se, via de regra, improdutivos; sua utilização representou, nestes casos, a diferença entre o sucesso e a necessidade de replantio. Apresenta-se uma revisão bibliográfica sobre turfa e suas propriedades agronômicas, bem como acerca da utilização de matéria orgânica na revegetação de áreas degradadas. O estudo constituiu um comparativo entre resultados de ensaios efetuados em amostras de solo provenientes de área abandonada pela mineração de areia, homogeneizadas em laboratório em seu estado original (branco), de um lado, e com adição de turfa em diferentes proporções, de outro, visando aferir se alguma delas poderia adequar-se mais satisfatoriamente à melhoria das condições gerais do solo em questão. Foram analisadas variações em propriedades químicas e físicas como retenção de cátions, efeito tampão, densidade aparente, condutividade hidráulica e porosidade. Abre-se a possibilidade de os resultados deste projeto não se limitarem apenas à Indústria Mineral mas estenderem-se a outros setores onde haja a necessidade de recuperação de solos, fornecendo subsídios a eventuais modificações no manejo de solos agricultáveis, com perspectivas de geração de economia de recursos em irrigação, fertilizantes e defensivos agrícolas. / The environmental recuperation of areas explored by sand mining in the Vale do Paraíba region, in the State of São Paulo, is a popular aspiration, a constitutional obligation and constitutes a differentiating factor in the visions of modern enterprise. This work studies the utilization of peat as a soil conditioner in the final stage of the recuperation process for these areas: the revival of indigenous vegetation. This idea arose from the author's experience in technological and mineral research into peat, coupled with the observation and monitoring of these environmentally sensitive areas, whose soils were, from an agricultural stance, generally unproductive. The utilization of peat, in these cases, represented the difference between success and the necessity for a replantation process. This study presents a review of the agronomic properties of peat as well as the application of organic matter in the revegetation of damaged land. It is a comparative study between laboratory assay results from soil samples in their original state, and those where the soil has variable peat contents, seeking to ascertain which, if any, results in better general conditions for that particular soil. Both physical and chemical properties were analyzed, with an emphasis on cation exchange capacity, buffering, bulk density, hydraulic conductivity and porosity. There is a possibility that the results of this project can extended beyond the Mineral Industry to other sectors, where there are needs for soil recuperation, leading to cost savings for irrigation, fertilizers and agrotoxic compounds in food production areas.

A presente dissertação começa com a evolução histórica de dois importantes institutos jurídicos, a fidúcia e a propriedade, a partir das raízes romanas. Já no direito brasileiro analisamos o conceito de negócio fiduciário e figuras afins, então passamos a estudar o contrato de alienação fiduciária. Em seguida abordamos a propriedade fiduciária, sua evolução legislativa no direito pátrio, e seus desdobramentos envolvendo móveis e imóveis, onde estabelecemos o conceito, a natureza jurídica, seus elementos constitutivos, e as conseqüências de seu inadimplemento. Não olvidamos o aspecto processual e as questões controvertidas, como a falência, a recuperação judicial e o cabimento ou não da prisão civil, dentre outros. No decorrer deste trabalho procuramos analisar crítica e comparativamente as figuras afins ao instituto da propriedade fiduciária e estabelecer as similitudes e diferenças em cada sistema estudado, assim como individualizar estes institutos previstos no Código Civil de 2002 e na Lei n. 9.514/97. Enfim, nosso estudo não estaria completo sem pesquisar a fidúcia nos sistemas francês, italiano e anglo-americano. / This paper begins with the historical evolution of two important legal institutes, trust and ownership, since the Roman roots. However, in Brazilian law we analyze the concept of deed of trust and similar institutions, thus we will study the chattel mortgage agreement. Afterward, we will focus fiduciary ownership, its legal evolution in the Brazilian law, as well as, its divisions involving real and personal property, in which we set forth the concept, legal nature, its constitutive elements and the consequences arisen from its non-performance. We have not forgotten the procedural aspect and controversial issues as: bankruptcy, judicial recuperation and the acceptance or not of civil imprisonment, among others. During this work we tried to analyze both critically and comparatively, similar figures of the fiduciary ownership institute and establish the similarities and differences in each of the systems we studied, as well as individualize the institutes provided in the Civil Code of 2002 and in Act No. 9.514/97. Finally, our study would not be complete without researching trust in the French, Italian and Anglo-American systems.

One of the main problems of urban land use is the environmental impacts caused by inadequate use of it. This worry comes from the moment that there is lack of preserved areas in cities due to land occupation and inadequate planning for urban use. This paper tries to establish in a systematized form a reference on planning for recuperation of degraded areas in urbanenvironments emphasizing some basic aspects to the recuperation of those. / Uno de los principales problemas de ocupación del suelo urbano son los impactos ambientales causados por su uso inadecuado. Esta preocupación se inicia en el momento cuando se nota la escasez de áreas reservadas en las ciudades debido al crecimiento urbano y a la falta de planifi- cación. En este artículo se trata de establecer de manera sistematizada una referencia sobre el planeamiento para la recuperación de áreas degradadas en ambiente urbano resaltando algunos aspectos básicos para la recuperación de las mismas. / Um dos principais problemas da ocupação do solo urbano são os impactos ambientais causadospelo uso inadequado deste.

The aim of the master’s thesis was to design ventilation and cooling systems in a three-storey mixed-use building, which contained three apartments and two dentists’ surgeries. Two independent ventilation systems were designed in the building, with respect to different purposes of the indoor spaces. The mechanical cooling system was proposed in some of the rooms to improve thermal comfort in summer. The thesis includes calculations of building heat gains, heat losses, air exchange rates and the dimensioning of the ventilation and cooling systems. The thesis also comprises design calculations and technical drawing.

The scope of this thesis investigates value added by a turbocharger with an associated motor-generator unit to a diesel engine used by a commercial vehicle. A thermodynamic model of the engine was prepared in GT-SUITE software. Case studies were primary focused on a reduction of specific fuel consumption as well as a nitrogen oxides production using an energy recuperation of exhaust gas. Furthermore, there are described potential benefits of using an electric assistance in order to increase an exhaust gas temperature during a steady state engine operation. Additionally, there is an investigation of potential benefits of a turbocharger assistance in a transition engine mode operating during rapid acceleration of the vehicle. The results of individual analysis will be taken into account for a selection of turbocharger regarding specific engine implementation. The results of simulation suggest that it is possible to lower specific fuel consumption, production of nitrogen oxides, as well as accelerate turbocharger response.

The diploma thesis is focused on the design of heating and forced ventilation for the project of the family house Doubrava. In the first two chapters is briefly described the theory and there is also described the project of the family house. The next chapter deals with the design of the forced equal pressure ventilation with the heat and moisture recovery. Than the heat loss are calculated according to the norm ČSN EN 12831-1. The next part is focused on the design of heating system and the heat source for the family house Doubrava. There is described detailed design of the floor heating, including necessary calculations, and also the type of the heat pump, as the heat source and source for hot water heating, is chosen. This part also contains a selection of expansion tank and safety valve and approximate calculation of the size of the primar circuit. The last part deals with the possibilities of using renewable energy sources. At the end of the thesis, there are more detailed results of the calculations and the mechanical drawings of individual designs of the ventilation and heating system and also there are tables of the acquisition costs.
