Neste trabalho foram investigadas oportunidades de redução das emissões de gases de efeito estufa (GEE) para uma refinaria brasileira de petróleo, através das seguintes etapas: levantamento das estratégias de enfrentamento do problema adotadas por algumas empresas; seleção de uma metodologia de estimativa de emissões de GEE para companhias de óleo e gás; elaboração do inventário da refinaria nacional através do programa aplicativo SANGEA; e proposição de opções para gestão das emissões de GEE dessa refinaria. Combustão e práticas de flaring e venting são os maiores contribuintes das emissões de GEE da cadeia produtiva. Quatro opções de mitigação estão sendo exploradas pelas empresas: aumento da eficiência energética, redução de flaring e venting, mudança para fontes energéticas menos intensivas em carbono e seqüestro de carbono. Neste estudo foi mostrado que o SANGEA é uma ferramenta de estimativa adequada, pois a emissão total de GEE obtida apresentou uma diferença de 1% em relação ao valor estimado pela Petrobrás. Melhoria da eficiência energética é a principal oportunidade de redução de emissões. Para a refinaria estudada foram descritos futuros projetos da área energética que apresentaram um potencial de emissão evitada de 270.000 t CO2 /ano. Por outro lado, a instalação de novas unidades para adequação dos teores de enxofre da gasolina e do diesel resultará na emissão adicional de 208.000 t CO2 /ano. Portanto, o sucesso dos esforços para economizar energia pode ser anulado pelas exigências ambientais para adequação da qualidade dos produtos. Isto ressalta a necessidade dos formuladores de política estabelecer um balanço entre as novas exigências para combustíveis (com impactos locais) e a política de abatimento de CO2 (com impactos globais) / Abstract: Fossil fuel burning is the main human contribution to global warming. In this study, opportunities for reducing greenhouse gas (GHG) emissions were investigated for a Brazilian oil refinery, according to the following steps: survey of climate change strategies adopted by some companies; selection of a methodology for calculating GHG emissions for the petroleum industry; development of an inventory for a national oil refinery by applying SANGEA software; and proposal of options for managing GHG emissions in this refinery. Combustion, flaring and venting are the largest contributors to GHG emissions in the production chain. Four mitigation options are being explored by companies: increasing energy efficiency, flaring and venting reduction, switching to less carbon-intensive sources of energy and carbon sequestration. It was demonstrated that SANGEA is a suitable estimation tool since the calculated total GHG emission showed 1% difference compared to Petrobras estimated value. Energy efficiency improvement is the main opportunity to reduce emissions. For the case study refinery future energy saving opportunities were described and their avoided emission estimation is 270,000 metric tonnes per year of CO2. On the other hand, new process units are required to comply with the gasoline and diesel stricter sulfur specifications, producing an additional emission of 208,000 metric tones per year of CO2. Thus, the successful energy saving efforts can be nullified by environmental requirements for fuel quality. This underlines the need for policy makers to strike a balance between new fuel requirements (with local impacts) and CO2 abatement policy (with global impacts) / Mestrado / Energia, Sociedade e Meio Ambiente / Mestre em Engenharia Mecânica

A tese propõe realizar uma abordagem acerca do importante patrimônio paisagístico brasileiro, com especial atenção aos jardins de interesse histórico, transitando pelas percepções e nuances do termo paisagem. O eixo central da pesquisa girou em torno da construção da ideia de paisagem cultural, no Brasil, a partir da década de 1930, e como o órgão de preservação federal (atual IPHAN) patrimonializou os bens do patrimônio paisagístico ao longo das décadas de 1930-2010. O objetivo geral foi contextualizar, qualificar e pontuar sob quais circunstâncias foi protegido o patrimônio paisagístico brasileiro, a partir da década de 1930, abordando e explicitando como se deu a construção da ideia de paisagem cultural, em diálogo com as normativas internacionais. Os Jardins Históricos, uma das categorias do Patrimônio Paisagístico brasileiro, é tema privilegiado nesta pesquisa por ter se tornado o carro chefe quando da criação do Departamento de Patrimônio Natural dentro do quadro burocrático e organizacional da SPHAN/próMemória, na década de 1980. A pesquisa aponta que o estudo destes bens evidencia um projeto patrimonial, arquitetônico e urbanístico maior, gestado ao longo do século XX, em que as formas de estar e se relacionar com a cidade, com a arquitetura do passado e, principalmente, com o patrimônio cultural se põem em destaque. Realiza-se, ainda, um Inventário do patrimônio paisagístico brasileiro, sistematizado em categorias tipológicas / Abstract: History drawings within the landscape line: landscape heritage and historic gardens in Brazil - Its memory, inventory and safeguard is a study of landscape heritage along with its cultural landscape and historic gardens during the twentieth century in Brazil. The thesis proposes to carry out an approach transiting perceptions and nuances of the term landscape with special attention to historic garden interests and important Brazilian landscape heritage. The central foundation of the research has revolved around the cultural landscape construction idea in Brazil from the 1930s on. And the federal organ preservation (current IPHAN) claimed property on the assets of the landscape heritage from 1930 to 2010. The overall objective was to contextualize, qualify and score the circumstances which protected the Brazilian landscape heritage from the 1930s on. Thus, addressing and explaining how the dialogue regarding the construction of cultural landscape idea at international standards was made. Historic Gardens, one of the Brazilian landscape heritage categories is the prevailing theme in this research as it became a main reference during the creation of the Natural Heritage Department in the 1980s within the bureaucratic and organizational framework of SPHAN / Pro-memoria.The research shows that the study of these assets presents a bigger heritage; architectural and urban project managed during the twentieth century in which the ways of being and relating to the city, to past architecture and especially to cultural heritage is put in the spotlight. An Inventory of the Brazilian landscape heritage systematized in typological categories is also made / Doutorado / Politica, Memoria e Cidade / Doutora em História

Professional school counselors frequently use career interest inventories as part of a comprehensive guidance program to help students create a post-secondary school plan. The present study evaluates the validity of three commonly used interest inventories, the Myers-Briggs Type Indicator, Self-Directed Search, and Strong Interest Inventory on field of study choice for graduating high school seniors (N = 616) from a large, suburban high school in Texas. Students identified their intended postsecondary field of study category, were randomly assigned using stratification to three groups, and each group completed a different inventory. Group membership was evaluated to establish covariate balance on a wide variety of indicators. Data from each group was evaluated to determine the extent to which the inventory predicted the chosen field of study, as well as Other and Undeclared categories using logistic regression models. None of the inventory models suggest that the inventory accurately predicts Other or Undeclared outcomes. For students selecting intended postsecondary fields of study, the Self Directed Search predicts such outcomes better than other measures. Professional school and career counselors should consider the SDS in addition to narrative counseling strategies to add greater precision with career decision making among clients and students.

Les composés organiques volatils (COV) jouent un rôle majeur au sein du système atmosphérique puisqu’ils interviennent en tant que précurseurs d’ozone troposphérique et d’aérosols organiques secondaires (composés aux divers impacts sanitaires et climatiques) ; d’où le réel besoin de mieux les caractériser. A ce jour, de fortes incertitudes demeurent quant à leur nature, leur quantification et la contribution de leurs sources d’émissions respectives.Cette thèse propose, au travers d’expérimentations de laboratoire et de terrain, une caractérisation exhaustive des COV et de leurs principales sources d’émissions en région Île-de-France. Les méthodes mises en place dans ce travail de thèse reposent sur la détermination de profils de spéciation caractéristiques du trafic routier, du chauffage au bois et du gaz naturel à partir d’investigations en champ proche (en tunnel, en cheminée et à partir d’un conduit de gaz domestique). Ces différents profils de source ont été utilisés comme empreinte chimique de référence pour l’identification des principales sources d’émissions de COV, dont les contributions respectives ont été estimées à l’aide du modèle source-récepteur Positive Matrix Factorization (PMF), appliqué sur une année d’acquisition de mesures COV (HCNM+COVO) à Paris. Ce travail de thèse a ainsi permis, pour la première fois, d’étudier la variabilité saisonnière des COV et de leurs sources majeures. Les émissions liées au trafic routier ont été révélées comme la principale source de COV d’origine locale/régionale à Paris (contribuant à ¼ des émissions totales à l’échelle annuelle). L’impact prépondérant du chauffage au bois en hiver (50 % de la masse totale COV mesurée) a également été mis en évidence. Les résultats de cette étude de répartition de sources ont été confrontés à l’inventaire des émissions d’Airparif. Nous avons souligné un bon accord entre nos observations et l’inventaire pour les sources liées au trafic automobile et au chauffage au bois.Cette évaluation indépendante des inventaires est essentielle puisque ces derniers sont aujourd’hui utilisés comme données d’entrée au sein des modèles de prévision de qualité de l’air. / Volatile organic compounds (VOCs) play a key role within the atmospheric system acting as precursors of ground-level ozone and secondary organic aerosols (causing health and climatic impacts); hence the growing interest of better characterizing them. Significant uncertainties are still associated with compounds speciation, quantification and respective contributions from the different emission sources.This thesis proposes, through several laboratory and intensive field campaigns, a detailed characterization of VOCs and their main emissions sources within the Île-de-France region. We used methods based on the determination of speciation profiles indicative of road traffic, wood burning and natural gas sources obtained from near-field investigations (inside a tunnel, at a fireplace and from a domestic gas flue). These different source profiles were used as chemical fingerprints for the identification of the main VOC emission sources, which respective contributions were estimated using the Positive Matrix Factorization (PMF) source-receptor model applied to one-year VOCs (including NMHC+OVOC) measurements in Paris. This thesis allowed, for the first time, to evaluate the seasonal variability of VOCs and their main emission sources. Road traffic-related emissions are major VOC local/regional sources in Paris (contributing to a quarter of total annual emissions). The important impact of wood burning in winter (50 % of the VOC total mass) was observed. Results obtained from this approach were compared with the regional emissions inventory provided by the air quality monitoring network Airparif. Finally, a good agreement was found between our observations and the inventory for road traffic and wood burning-related sources.This independent assessment of inventories is of great interest because they are currently used as input data within air quality prediction models.

En réponse aux changements climatiques avérés et à une qualité de l'air qui se dégrade, la quantification des émissions de gaz à effet de serre et des polluants atmosphériques des régions urbanisées suscite un intérêt croissant. La meilleure description des émissions anthropiques actuellement disponible est proposée par les inventaires d'émission. Mais leurs estimations, fournies par secteur, reposent sur la combinaison de données d'activité et de facteurs d'émission déterminés sur bancs d'essai et qui ne représentent pas forcément bien les conditions réelles d'émission. Paris, en tant que 3e mégapole européenne, se place dans ce contexte et nous avons choisi d'utiliser des méthodes reposant sur l'acquisition de mesures in situ en région parisienne pour caractériser le signal urbain et vérifier les estimations de l'inventaire régional haute résolution d'Airparif. Les méthodes mises en place dans ce travail de thèse reposent sur l'utilisation conjointe de différents traceurs atmosphériques (CO, NOx, COV). En effet, ils sont co-émis au CO2 lors des processus de combustions incomplètes dans des proportions supposées caractéristiques du secteur d'émission. Les rapports de concentration entre les différentes espèces co-émises sont donc un outil de choix pour cette étude. Nous avons alors développé différentes méthodes d'évaluation de ces rapports pour caractériser les émissions pour l'une des sources prédominantes de CO2 à Paris (le trafic routier) ou dans le panache parisien. Les variabilités spatiale et saisonnière des rapports ont notamment pu être étudiées et les conclusions obtenues n'étaient pas forcément référencées dans les estimations des inventaires ou d'études antérieures. Nous avons comparé nos résultats aux estimations fournies par l'inventaire le plus récent d'Airparif qui apparait généralement surestimer ces rapports. Enfin, nous avons combiné les résultats de l'approche multi-espèces à ceux fournis par l'analyse des isotopes du carbone dans le CO2 (souvent utilisés comme référence pour l'étude des émissions anthropiques). D'après leur analyse, les émissions de CO2 à Paris sont majoritairement d'origine fossile (81 %) et l'utilisation des combustibles fossiles est répartie quasi équitablement. Finalement, l'accord satisfaisant trouvé entre les deux démarches (multi-espèces et isotopique) a permis d'affirmer leur pertinence pour l'étude des signaux urbains moyens. / In response to changing air quality and climate, there is a growing interest in quantifying emissions ofatmospheric pollutants and greenhouse gases from urban areas. Currently emission inventories provide the most detailed description of anthropogenic emissions. However, their estimates rely on the combination of activity proxies and emission factors for individual source sectors calibrated for benchmarck situations that may significantly differ from real conditions. Paris, the third largest megacity in Europe, can be considered in this context. We used methods based on in situ measurements in this region to characterise the urban signal and independently assess the latest estimates from the regional inventory. The methods we developed rely on the joint analysis of atmospheric tracers (CO, NOx, VOCs) which are co-emitted with CO2 during incomplete combustion processes in ratios that are characteristic of each emission sector. These ratios between co-emitted species are thus an appropriate tool to study the urban signal. During this PhD, we developed several methods to evaluate the ratios using measurements for a major CO2 emission source in Paris (road traffic) or for measurements acquired in the urban atmosphere. We revealed spatial and seasonal variabilities in these ratios and the main conclusions were not necessarily in complete accordance with the ones from inventories or previous studies. We also compared our results to the estimates provided by the latest regional inventory, which appears to overestimate them in most cases. Finally, we combined the results obtained with the multi-species analysis to the ones provided by isotopic analyses (which are often used as a reference to study anthropogenic emissions). According to the analyses of these measurements, CO2 emissions in Paris came mostly from combustion of fossil fuels (81 %) and the use of each fossil fuel is almost equally distributed. Finally, the satisfactory agreement found between the two approaches (multi-species and isotopic one) confirmed their relevancefor the analysis of mean urban signals.
