<p>This dissertation examines the political response of gay and lesbian organizations to the HIV/AIDS crisis through the lens of disability. When the National Gay Task Force (NGTF) formed in the 1970s, their early political efforts confronted the stigma and exclusion associated with the American Psychiatric Association’s disabling label. In the 1980s, gay and lesbian organizations faced a deadly epidemic—AIDS. The high cost of medical care left people with AIDS destitute. NGTF pressed the Social Security Administration to modify their disability criteria to recognize AIDS and ARC as qualifying disabilities. Fear and homophobia left people with AIDS vulnerable to employment, housing and medical discrimination as well as social ostracism. Gay Men’s Health Crisis and Lambda Legal Defense and Education Fund countered AIDS discrimination in New York through collaborative efforts with city and state agencies. Disability rights codes and laws offered people with AIDS some protection against discrimination. The Task Force, the Gay Rights National Lobby and the Disability Rights Defense & Education Fund joined the Leadership Conference on Civil Rights in 1982. While the Conference did not engage in the campaign for gay and lesbian rights in the 1980s, their extended legislative crusade for the Civil Rights Restoration Act would bring AIDS onto the battlefield. This study finds these various antecedents came into play during the Americans with Disabilities Act (ADA) to the extent that gay and lesbian organizations could describe the ADA as an “AIDS bill” in terms of both their political participation and the text protecting people with contagious diseases who were not a threat.<br></p>

Selecting employees for hire and promotion is one of the most essential functions of an organization. Many companies that have positions which contain a physical component rely on physical ability testing as part of their selection procedure. The establishment of both the Civil Rights Act and the Americans with Disabilities Act (ADA) had a profound impact on the manner in which selection testing may legally be conducted (Gutman, Koppes, & Vodanovich, 2011). The current study sought to analyze court cases involving physical ability testing. Results revealed that pure ability tests did not significantly differ from work sample tests with regard to whether court cases found for the plaintiff or defendant. Additionally, rulings did not significantly differ in ruling in favor of the plaintiff or defendant with regard to whether the position in question involved public safety. Finally, the ADA related cases did not significantly differ in their rulings in favor of the plaintiff or defendant after the 2011 modifications to the interpretation of disabled, as compared to before 2011. Future research should focus on the difference between court rulings involving physical ability tests in comparison to other forms of testing such as cognitive tests, and further investigate the role of the ADA in physical ability testing.

Nessa prov?ncia encontram-se as maiores descobertas realizadas no mundo nos ?ltimos dez anos; as ?reas de Libra, de Franco e o Campo de Lula, todas com volumes superiores a 8 bilh?es de barris de ?leo recuper?veis. Para desenvolver e otimizar a produ??o desses campos, foi feito um estudo para escolha dos m?todos de recupera??o avan?ada, tendo como principais motiva??es a presen?a do di?xido de carbono (CO2) como contaminante e a decis?o estrat?gica de n?o o descartar, combinada ? alta RGO (raz?o g?s-?leo) do fluido do reservat?rio. O m?todo deveria tirar vantagem dos ?nicos recursos abundantes: a ?gua do mar e o g?s produzido. Dessa maneira, o processo de combinar esses recursos na inje??o alternada de ?gua e g?s (WAG) passou a ser visto como uma boa op??o. Nessa disserta??o, foi desenvolvido um modelo de reservat?rio com caracter?sticas do pr?-sal brasileiro, sendo aplicado o m?todo de recupera??o avan?ada de inje??o alternada de ?gua e g?s. O potencial de produ??o desse reservat?rio foi analisado por meio de par?metros como: fluido que inicia o processo de inje??o, posi??o das completa??es dos po?os injetores, bem como vaz?es de inje??o de ?gua e de g?s e o tempo de ciclo de cada fluido injetado. Os resultados mostraram um bom desempenho do m?todo WAG-CO2 misc?vel, com ganhos de at? 26% no FR com rela??o a recupera??o prim?ria, j? a aplica??o da inje??o de ?gua e de g?s, de maneira individual, n?o foi capaz de superar o patamar de 10% de ganho. O par?metro de maior influ?ncia nos resultados foi o tempo de ciclo, com maiores valores de FR obtidos com a utiliza??o dos menores tempos. / The pre-salt province is composed by large amounts of light oil and with good quality, a reality that puts Brazil in a strategic position facing the great demand for energy worldwide. In this province are the largest discoveries in the world in the last ten years; areas as Libra, Franco and Lula field, everyone containing volumes greater than 8 billion recoverable oil barrels. To develop and optimize the production of these fields, a study was done for choosing the improved oil recovery methods. The main motivations were the presence of carbon dioxide (CO2) as a contaminant and the strategic decision of do not discard it, combined with high GOR (gas-oil ratio) of the reservoir fluid. The method should take advantage of the unique abundant resources: seawater and produced gas. This way, the process of matching these resources in the water alterning gas injection (WAG) became a good option. In this master?s dissertation, it was developed a reservoir model with average characteristics of the Brazilian pre-salt, where was applied the improved oil recovery method of water alternating gas. The production of this reservoir was analyzed by parameters as: the first fluid injected in the injection process, position of the injection wells completion, injection water and gas rate and cycle time. The results showed a good performance of the method, with up to 26% of gains in the recovery factor regarding the primary recovery, since the application of water injection and gas, individually, was not able to overcome 10 % of gain. The most influential parameter found in the results was the cycle time, with higher recovery factor values obtained with the use of shorter times.

Com isso, as empresas vêm buscando soluções e ferramentas para minimizar esse risco ambiental. Deste modo, é de suma importância o estudo da indústria coureira, por ser uma grande produtora de resíduos e subprodutos de alto potencial de impacto ambiental pela grande quantidade de água e componentes químicos envolvidos em toda cadeira produtiva. O objetivo geral deste trabalho é desenvolver uma estrutura metodológica coerente e suficiente para a ADA aplicada na indústria coureira baseada nos aspectos referentes à estabilidade ambiental. O método de pesquisa utilizado neste estudo foi composto de dez etapas: i) levantamento bibliográfico sobre ADA; ii) mapeamento e estudo das etapas do processo produtivo do couro; iii) inventário dos resíduos sólidos, efluentes líquidos, emissões gasosas e subprodutos gerados nas etapas produtivas na fabricação do couro; iv) cálculo das contribuições potenciais das emissões, utilizando o método EDIP; v) descarte de categorias sem impacto ambiental; vi) normalização; vii) ponderação relativa entre critérios e alternativas ambientais; viii) desenvolvimento de um Índice de Desempenho Ambiental (Ida); ix) Estudo multicasos (coleta de dados e aplicação da estrutura criada); e x) quantificação dos resultados finais. De posse dos resultados apresentados, foi realizado, então, o cálculo do Índice de desempenho ambiental (Ida) para as empresas estudadas, chegando-se a um resultado de 89,826% para a empresa A, 82,284% para a empresa B e 81,71% para empresa C, o que significa que porcentagem dada dos resíduos e subprodutos gerados por estas empresas apresentam destinação ambiental adequada em termos da metodologia ADA aplicada neste estudo. Apesar das empresas estudadas apresentarem diferentes resíduos com destinação considerados ambientalmente inadequados, há uma proximidade no Índice de desempenho ambiental (Ida). Tal fato se justifica, pois as três empresas estudadas apresentam uma destinação considerada adequada para a o lodo do caleiro, que é o resíduo com maior contribuição na formação do Ida. Dessa forma, a aplicação do Ida em indústrias coureiras, evidencia ser uma ferramenta adequada para a avaliação do desempenho ambiental com base nos potenciais ambientais, tendo em vista que seus resultados permitem aos gestores das empresas tomarem medidas corretivas em seus processos de fabricação e, assim, melhorarem o seu desempenho ambiental. É uma ferramenta que pode ser utilizada amplamente pelo setor curtumeiro para minimização dos riscos ambientais e melhorias na gestão ambiental empresarial. / With the acceleration of modernization and the enormous consumption of resources, the emission of hazardous substances has become a problem for environmental health. With this, companies have been seeking solutions and tools to minimize this environmental risk. In this way, the study of the hull industry is of great importance, as it is a great producer of waste and by-products with high potential of environmental impact due to the large amount of water and chemical components involved in any productive chair. The general objective of this work is to develop a coherent and sufficient methodological framework for the EPE applied in the tannery industry based on aspects related to environmental stability. The research method used in this study was composed of ten steps: i) bibliographic survey on EPE; ii) mapping and study of the stages of the leather production process; iii) inventory of solid wastes, liquid effluents, gaseous emissions and by-products generated in the production stages in the manufacture of leather; (iv) calculation of potential emission contributions using the EDIP method; v) disposal of categories without environmental impact; vi) standardization; vii) relative weighting between environmental criteria and alternatives; viii) development of an Environmental Performance Index (Iep); ix) Case study (data collection and application of the structure created); and x) quantification of the final results. With the results presented, the calculation of the Environmental Performance Index (Iep) was carried out for the companies studied, reaching a result of 89.826% for company A, 82.284% for company B and 81.71% % For company C, which means that given percentage of the residues and by-products generated by these companies present adequate environmental allocation in terms of the ADA methodology applied in this study. Although the studied companies present different waste with destination considered environmentally inadequate, there is a proximity in the Index of environmental performance (Iep). This fact is justified, since the three companies studied have a destination considered suitable for the sludge of the beamhouse, which is the residue with the greatest contribution in the formation of Iep. Thus, the application of Ida in the weeding industry, proves to be an adequate tool for the evaluation of the environmental performance based on environmental potentials, considering that its results allow the managers of the companies to take corrective measures in their manufacturing processes and, thus Improve their environmental performance. It is a tool that can be widely used by the tanning industry to minimize environmental risks and improve environmental management.

For solution of the governing equations, written in the parabolic boundary layer and stream-function formulation, it was employed the hybrid, numericalanalytical, approach known as Generalized Integral Transform Technique (GITT). The flow is sustained by a pressure gradient and the magnetic field is applied in the direction normal to the flow and is assumed that normal magnetic field is kept uniform, remaining larger than any other fields generated in other directions. In order to evaluate the influence of the applied magnetic field on both entrance regions, thermal and hydrodynamic, for this forced convection problem, as well as for validating purposes of the adopted solution methodology, two kinds of channel entry conditions for the velocity field were used: an uniform and an non-MHD parabolic profile. On the other hand, for the thermal problem only an uniform temperature profile at the channel inlet was employed as boundary condition. Along the channel wall, plates are maintained at constant temperature, either equal to or different from each other. Results for the velocity and temperature fields as well as for the main related potentials are produced and compared, for validation purposes, to results reported on literature as function of the main dimensionless governing parameters as Reynolds and Hartman numbers, for typical situations. Finally, in order to illustrate the consistency of the integral transform method, convergence analyses are also effectuated and presented / O prop?sito do estudo desenvolvido nesse trabalho est? relacionado com a din?mica do escoamento incompress?vel, laminar, em regime permanente, com transfer?ncia de calor, de um fluido newtoniano condutor el?trico, no interior de um canal de placas planas paralelas, submetido a um campo magn?tico externo uniforme. Para a solu??o das equa??es de governo, modeladas atrav?s da formula??o parab?lica de camada limite em fun??o corrente, foi empregado o m?todo h?brido, num?rico-anal?tico, conhecido como T?cnica da Transformada Integral Generalizada (GITT). O escoamento analisado ? sustentando por um gradiente de press?o e assume-se que o campo magn?tico externo, aplicado na dire??o normal ao escoamento, permanece uniforme, muito maior do que quaisquer outros campos gerados em outras dire??es, n?o sendo, dessa forma, influenciado por nenhum efeito magn?tico interno. Para avaliar a influ?ncia do campo magn?tico sobre o desenvolvimento t?rmico e hidrodin?mico desse problema de convec??o for?ada, e tamb?m para fins de valida??o da metodologia de solu??o adotada, foram empregados dois tipos de condi??es de contorno para o campo de velocidade na entrada no canal: perfil uniforme e perfil parab?lico do escoamento sem campo magn?tico completamente desenvolvido. Para o problema t?rmico, por outro lado, empregou-se apenas o perfil uniforme de temperatura na entrada do canal e considerou-se que as placas se mant?m ? temperatura constante, iguais ou diferentes uma da outra. Resultados para os campos de velocidade, temperatura e potenciais correlatos s?o produzidos e comparados aos da literatura em fun??o dos principais par?metros de governo, a saber, n?mero de Reynolds, n?mero de Hartmann e par?metro el?trico, para algumas situa??es t?picas. Com o objetivo de ilustrar a consist?ncia da t?cnica da transformada integral generalizada, an?lises de converg?ncia s?o tamb?m efetuadas e apresentadas

The recent changes in the world scenario, the large reserves of heavy oils and also the lack of new discoveries of large petroleum fields are indications that, in the near future, the oil recovery by conventional methods will be limited. In order to increase the efficiency of the extraction process, enhanced recovery methods are cited in applications where conventional techniques have proven to be little effective. The injection of surfactant solutions as an enhanced recovery method is advantageous in that surfactants are able to reduce the interfacial tensions between water and oil, thus augmenting the displacement efficiency and, as a consequence, increasing the recovery factor. This work aims to investigate the effects of some parameters that influence the surfactant behavior in solution, namely the type of surfactant, the critical micelle concentration (CMC) and the surface and interface tensions between fluids. Seawater solutions containing the surfactants PAN, PHN and PJN have been prepared for presenting lower interfacial tensions with petroleum and higher stability under increasing temperature and salinity. They were examined in an experimental apparatus designed to assess the recovery factor. Botucatu (Brazil) sandstone plug samples were submitted to assay steps comprising saturation with seawater and petroleum, conventional recovery with seawater and enhanced recovery with surfactant solutions. The plugs had porosity between 29.6 and 32.0%, with average effective permeability to water of 83 mD. The PJN surfactant, at a concentration 1000% above CMC in water, had a higher recovery factor, causing the original oil in place to be recovered by an extra 20.97%, after conventional recovery with seawater / O petr?leo ? uma combina??o complexa de v?rias s?ries de hidrocarbonetos, sendo as mais comumente encontradas as parafinicas, naft?nicas e arom?ticas. As recentes mudan?as no cen?rio mundial, as grandes reservas de ?leos pesados, bem como a escassez de descobertas de grandes campos de petr?leo, indicam que em um futuro pr?ximo a recupera??o de ?leo por m?todos convencionais ser? limitada. Para aumentar a efici?ncia do processo de extra??o, faz-se uso dos m?todos avan?ados de recupera??o para agir nos pontos onde o processo convencional mostrou-se pouco eficiente. A inje??o de solu??o de tensoativo, como um m?todo avan?ado de recupera??o mostra-se vantajosa, pois os tensoativos t?m a finalidade de reduzir as tens?es interfaciais entre a ?gua e o ?leo, ampliando a efici?ncia de deslocamento e, conseq?entemente, aumentando o fator de recupera??o. Este trabalho se prop?s a estudar os efeitos dos par?metros que influenciam as solu??es de tensoativos, como: tipo de tensoativo, concentra??o micelar cr?tica e tens?o superficial e interfacial entre os fluidos. As solu??es com ?gua do mar dos tensoativos PAN, PHN e PJN, por apresentarem menores tens?es interfaciais com o petr?leo e maior estabilidade com o aumento da temperatura e salinidade, foram estudadas em um aparato experimental para avalia??o do fator de recupera??o. Os testemunhos de arenito Botucatu foram submetidos a etapas de satura??o com ?gua do mar e petr?leo, recupera??o convencional com ?gua do mar e recupera??o avan?ada com solu??es de tensoativos. Os testemunhos apresentaram porosidade entre 29,6 e 32,0%, com permeabilidade m?dia efetiva ? ?gua de 83 mD. O tensoativo PJN, com concentra??o de 1000% acima da CMC apresentou maior fator de recupera??o, aumentando em 20,97% a recupera??o do ?leo original in place ap?s a recupera??o convencional com ?gua do mar
