Fallow is a creative non-fiction book of memory and place. It chronicles the lives of William and Vera Lutz and their lives of struggle on the Northern Plains of North Dakota. It follows a narrator and his attempts to make sense of, and connect to their, lives following both of their deaths. It examines the life of William as the life left behind, and the life of Vera as the life continually felt, but never known. The chapters are held together by the quest of the narrator and a rumination on the idea that the sometimes brutal nature of prairie life shapes the lives of those who live there. That is, this story could not happen in any other place. / Graduation date: 2003

A amostra foi composta por 50 prontuários e 50 blocos de parafina contendo espécimes biopsiados de lesões orais, ambos provenientes de pacientes portadores de paracoccidioidomicose diagnosticados no Serviço de Estomatologia do Hospital São Lucas da PUCRS no período compreendido entre os anos de 1977 e 2010. Informações sobre tempo de evolução da doença, número e tamanho das lesões orais, bem como contagem de eritrócitos, leucócitos, linfócitos, hematócrito, hemoglobina e eritrossedimentação foram coletadas dos prontuários dos pacientes. Cortes histológicos obtidos a partir dos espécimes em parafina foram submetidos às colorações de hematoxilina e eosina (H&E), Gomori-Grocott e processamento imunoistoquímico. As amostras foram agrupadas de acordo com a intensidade de compactação do granuloma, e as variáveis número de fungos, número de brotamentos, diâmetro dos fungos, diâmetro dos brotamentos, expressão imunoistoquímica de IL-2, TNF-alfa e IFN-gama foram avaliadas e correlacionadas. O diâmetro dos brotamentos foi significativamente maior nos granulomas de compactação intermediária quando comparados aos granulomas de maior compactação. As demais variáveis (número de brotamentos, número e diâmetro dos fungos, expressão de IL-2, TNF-alfa e IFN-gama, características clínicas e hematológicas) não exibiram alteração significativa de acordo com o grau de compactação dos granulomas. Foi observada correlação positiva entre número de brotamentos e número de fungos (r=0.834); diâmetro dos brotamentos e diâmetro do fungo (r=0.496); eritrócitos e número de fungos (r=0.420); eritrócitos e número de brotamentos (r=0.408); leucócitos e número de brotamentos (r=0.396). A correlação negativa ocorreu entre diâmetro e número de fungos (r=-0.419); diâmetro dos brotamentos e compactação do granuloma (r=-0.367); expressão de TNF-alfa e número de fungos (r=-0.372); expressão de TNF-alfa e número de brotamentos (r=-0.300). As características histológicas, imunológicas e clínicas das lesões orais da paracoccidioidomicose crônica não diferiram significativamente entre os pacientes da amostra avaliada. Os níveis de TNF-alfa nas lesões orais estão inversamente relacionados à intensidade da infecção. / The present study aimed at analyzing histomorphometric, immunohistochemical and clinical features of oral lesions of paracoccidioidomycosis. The sample comprised 50 medical charts and 50 paraffinized blocks of biopsed specimens of oral leisons, both from paracoccidioidomycosis patients diagnosed at Stomatology Department of Hospital São Lucas, PUCRS from 1977 to 2010. Data regarding disease duration, and size and number of oral lesions, as well as erythrocytes, leukocytes, lymphocytes, hematocrit, hemoglobin and erythrocyte sedimentation rate, were collected from medical charts. Histological cuts were obtained from the paraffinized specimens and subjected to hematoxylin and eosin (H&E), Gomori-Grocott and immunohistochemical staining. The sample was classified according to the density of granulomas, and the variables number and diameter of fungi, number and diameter of buds, and IL-2, TNF-alpha and IFN-gamma expression were analyzed and correlated. Bud diameter was significantly greater in intermediate density granulomas compared to higher density granulomas. The other variables (bud number, number and diameter of fungi, expression of IL-2, TNF-alpha and IFN-gamma, and clinical and hematological features) did not significantly change with the density of granulomas. There was a positive correlation between bud number and fungal cell number (r=0.834), bud diameter and fungal cell diameter (r=0.496), erythrocytes and number of fungi (r=0.420), erythrocytes and bud number (r=0.408), and leukocytes and bud number (r=0.396). Negative correlation occurred between number and diameter of fungal cells (r=-0.419), bud diameter and granuloma density (r=-0.367), TNF-alpha expression and number of fungal cells (r=-0.372), TNF-alpha expression and bud number (r=-0.300). Histological, immunological and clinical characteristics of oral lesions of chronic paracoccidioidomycosis did not differ significantly between patients in our sample. TNF-alpha levels in oral lesions were inversely correlated with intensity of infection.

Para elaborar esse estudo foi analisada a trajetória da cientista e militante feminista, Bertha Maria Júlia Lutz (18941976), contemplando principalmente sua atuação como representante do Museu Nacional do Rio de Janeiro no Conselho de Fiscalização das Expedições Artísticas e Científicas do Brasil, entre os anos de 1939 e 1951. Bertha Lutz foi uma das primeiras mulheres brasileiras a ingressar oficialmente em uma instituição científica, depois de ser aprovada em concurso público para o cargo de ¿secretário¿ do Museu Nacional, em 1919. Nesse mesmo ano, fundou uma associação feminista intitulada Liga Pela Emancipação Intelectual da Mulher e, desde então, dedicou-se intensamente às ciências e ao movimento feminista. Com o passar dos anos, deixou o cargo de ¿secretário¿ para assumir o de naturalista, consolidando uma carreira estável e bem-sucedida em ciências naturais. Como membro do Conselho de Fiscalização, participou do processo de construção da nascente política científica nacional, fiscalizando e licenciando expedições científicas realizadas em território brasileiro. Apoiando-se na idéia recorrente na bibliografia sobre gênero e ciências e história das mulheres de que a participação feminina nas ciências foi maior do que imaginamos, mas poucos são os registros existentes e os olhares lançados sobre essa experiência, consideramos que resgatar e analisar trajetórias de mulheres que atuaram como cientistas, relacionando essas experiências com seus contextos específicos, é um passo importante para que possamos compreender os diferentes modos pelos quais o gênero influenciou e continua influenciando a construção de práticas científicas, e para refletir sobre as influências sociais, políticas e econômicas que atingem essas práticas / Abstract: This dissertation discusses the participation of women in sciences with the objective of understand which conditions, factors and strategies had influenced the feminine access to Brazilian¿s scientific institutions at the beginning of 20th century. To elaborate this study we analyzed the trajectory of the scientist and feminist, Bertha Maria Júlia Lutz (18941976), contemplating mainly its performance as representative of the National Museum of Rio de Janeiro in the ¿Brazilian Inspection Council on Artistic and Scientific Expeditions¿, between the years of 1939 and 1951. Bertha Lutz was one of the first Brazilian women civil servant, after being approved in a public competition for the position of ¿secretary¿ of the National Museum, in 1919. In this same year, she created a feminist association entitled ¿League for the Intellectual Emancipation of Woman¿ and, since then, dedicated herself intensely to practice sciences and to the feminist movement. A few years later, she left the position of ¿secretary¿ to assume the position of naturalist, and consolidated a steady and well-succeeded career in natural sciences. As member of Inspection Council, she took part in the process of formulating national scientific policies, process that was just starting in Brazil. Based on the recurrent idea present in the bibliography on gender and sciences and women¿s history that the feminine participation in sciences was more important than we imagine, but there are few registers and a small number of analyses about this experiences, we consider that to rescue and to analyze trajectories of women that had worked as scientists, relating these experiences with its specific contexts, are an important contribution and can help the understanding of the different ways in which the gender influenced and it continues to influence the construction of sciences, and to reflect about the social, economical and political influences, that affects the scientific activity / Mestrado / Mestre em Política Científica e Tecnológica

Im Rahmen eines grossangelegten Modernisierungsprogramms des CERN Beschleunigerkomplexes zur Steigerung der Intensität der Protonenstrahlen wird in einer ersten Phase der Protonenbeschleuniger Linac2 durch einen H− Ionen Beschleuniger Linac4 ersetzt. Um den Ionenstrahl an die einzelnen Beschleunigerelemente des Linac4 anzupassen sind drei Strahltransportsektionen notwendig. Diese sind aufgrund ihrer strahldynamischen Eigenschaften sensitive Stellen für ungewolltes Emittanzwachstum und Teilchenverluste und sind im Schwerpunkt dieser Thesis. Die erste Strahltransportsektion, „Low Energy Beam Transport”(LEBT), befindet sich zwischen der Teilchenquelle und dem ersten Beschleunigerelement, den Radiofrequency Quadrupole (RFQ). Im Rahmen dieser Thesis wurde das LEBT in Betrieb genommen, dessen Strahldynamik rekonstruiert und die Leistungslimitierungen experimentell bestimmt. Der zweite Teil der Thesis ist auf die Auslegung und Strahldynamik der Transfer Linie zwischen Linac4 und dem Proton Synchrotron Booster(PS-Booster) konzentriert. Die Strahldynamik der Transferlinie wurde optimiert und teilweise komplett überarbeitet. Die neue Transferlinie zeichnet sich durch eine verbesserte Emittanzerhaltung, höhere Stabilität der Strahldynamik gegenüber Aufstellungsfehlern und Feldjittern der Magnete und durch eine optimale Anpassung der Strahlparameter an die verschiedenen Injektionsschemata des PS-Boosters aus. Für eine abschließenden „Start-To-End” Simulationen wurden die Strahlcharakteristiken, die bei der Inbetriebnahme des LEBTs bestimmt worden sind, als Anfangsbedingungen für die strahldynamische Simulation von Linac4 einschließlich Transferlinie genutzt. Mit Hilfe dieser „Start-To-End” Simulationen werden kritische Positionen der Strahldynamik identifiziert, die durch Teilchenverluste oder Emittanzwachstum gekennzeichnet sind. Eine besonders kritische Sektion stellt das „Medium Energy Beam Transport” da, dessen Optik auf die neuen Strahlparameter angepasst werden musste. / In the first phase of the upgrade program of the CERN accelerator complex the proton injector Linac2 will be replaced by a new, normal-conducting H− ion Linac, Linac4, allowing a significant increase of the proton flux intensity along the downstream accelerator complex. In the design of Linac4 three beam transport sections are implemented to match the beam between the different accelerator elements and to model the longitudinal pulse structure. These three beam transport sections, which are the most critical locations in terms of beam quality preservation, are in the focus of this thesis. During the work of this thesis the Low Energy Beam Transport (LEBT), which is required to match the source beam to the radiofrequency quadrupole (RFQ), has been commissioned and its beam dynamics re-constructed. The measurement campaign used to reconstruct the LEBT beam dynamics was performed with the aim to prepare the RFQ commissioning and to maximise the LEBT performance. Downstream of the Linac4 accelerator the beam is transported along a 180m long transfer line to the Proton Synchrotron Booster (PS-Booster). The transfer line optics was studied, optimised and sections were completely re-designed. The new transfer line optics is characterised by an improved preservation of the beam emittance, higher stability of the optical solution with respect to alignment errors and field jitters of the transfer line magnets and it is matched to each of the PS-Booster injection schemes. In a concluding ”Start-To-End” simulation based on the measured beam characteristics at the LEBT exit the beam dynamics of the downstream Linac, including the transfer line, was calculated. To minimise particle losses within acceptable emittance preservation the beam optics of the Medium Energy Beam Transport (MEBT) was adapted to the measured beam parameters. This ”Start-To-End” simulation was performed to identify critical sections of the Linac4 beam dynamics and to adjust the commissioning strategies.
