OBSERVING EXOPLANET TRANSITS WITH THE CITIZEN CONTINENTAL-AMERICA TELESCOPIC ECLIPSE (CATE) EXPERIMENT TELESCOPE NETWORK

Baer, Robert A. 01 May 2019 (has links)
The Citizen Continental-America Telescopic Eclipse (CATE) Experiment established a standardized set of observation procedures and 72 volunteer observation teams with identical equipment along the path of the 2017 total solar eclipse. CATE successfully imaged the solar corona from 66 of the 72 observation sites resulting in a high dynamic range animation of 90 minutes of solar corona data collected by volunteer citizen science teams. A subgroup of CATE began work in the fall of 2017 to evaluate use of the standard CATE observation setup for exoplanet transit observations. Light curves and analysis of data using AstroImageJ of two well know transiting exoplanets, HD209458b (V = 7.65, depth = 1.5%) and HD189733b (V= 7.67, depth=2.4%) are presented along with modifications to CATE telescopes required for successful exoplanet follow up observations.

No. of bitstreams: 1 Juliana Stolze Efeito...2015.pdf: 1337321 bytes, checksum: 6fdad9cde6d0cc06bd37fdbe677450ae (MD5) Previous issue date: 2015 / Fundação Oswaldo Cruz, Centro de Pesquisas Gonçalo Moniz. Salvador, BA, Brasil / Introdução: as doenças cardiovasculares acometem milhares de pessoas no mundo. Destas, a doença arterosclerótica está entre as de maior morbimortalidade. Para a avaliação da necessidade de intervenções hemodinâmicas e/ou revascularização miocárdica, há a necessidade da realização do cateterismo (CATE), procedimento de imagem indicado para evidenciar pontos de obstrução e determinar a melhor estratégia cirúrgica. Para a realização do CATE utiliza-se heparina sódica (5000 UI) in bolus. Atualmente, sabe-se que a heparina interfere no remodelamento de partículas lipoproteicas por liberação da lipoproteína lipase (LPL) e da lipase hepática (LH), essa ação pode alterar o transporte reverso do colesterol (TRC), em função de modificações no metabolismo das lipoproteínas. Métodos: foram selecionados por conveniência 20 pacientes, 10 do sexo masculino e 10 do sexo feminino, ambos os sexos, entre 45 e 73 anos, admitidos no Hospital Ana Neri, submetidos à cineangiocoronariografia (CATE). Todas as determinações laboratoriais foram realizadas antes e depois do CATE. Resultados: houve aumento significativo da atividade da lipase e diminuição da concentração dos triglicérides depois do CATE na análise geral e estratificada pelo sexo (p<0,05; Teste t pareado). A razão HDL-C/apoA aumentou significativamente depois do CATE, já a razão LDL-C/apoB não aumentou, nem diminuiu nas análises geral e estratificada por sexo. Enquanto a razão de risco cardiovascular TG/HDL-C diminuiu significativamente, a ApoB/apoA aumentou significativamente na análise geral e estratificada por sexo depois do CATE. As análises de correlações tiveram comportamentos diferentes, sendo a significância estatística encontrada dependente do grupo analisado (geral, masculino e feminino). A concentração do não-HDL-C, semelhante à determinação da haptoglobina, tiveram diminuição significativa na análise geral e no sexo masculino depois do CATE (p<0,05; Teste t pareado), o grupo feminino não mostrou significância. As taxas de incorporação de colesterol livre e fosfolípides não foram significativas depois do CATE. Conclusão: A administração in bolus de heparina sódica interfere no remodelamento de partículas lipoproteicas, sendo este fato evidenciado pelas variações das razões de risco, tais como, HDL-C/apoA, TG/HDL-C. O percentual de incorporação dos fosfolípides e colesterol livre na HDL mostrou-se influenciado em relação ao sexo, o que o torna relevante dado aos resultados encontrados. A utilização de razões de risco e ainda suas correlações mostraram-se melhores indicadores de desfecho sugestivo de doença cardiovascular nessa casuística do que quando avaliados apenas os marcadores séricos do perfil lipídico isoladamente. / Introduction: cardiovascular diseases affect thousands of people worldwide. Of these, the atherosclerotic disease is one of the most morbidity and mortality. To evaluate the need for hemodynamic interventions and / or CABG, the catheterization (CATE) is performed, an imaging procedure to evidence obstruction and to determine the best surgical strategy. To perform CATE, is necessary to use in bolus sodium heparin (5000 IU). Currently, it is known that heparin interferes with the remodeling of the lipoprotein particles by releasing lipoprotein lipase (LPL) and hepatic lipase (HL), this action may alter the reverse cholesterol transport (TRC), by changes in lipoprotein metabolism. Methods: were selected by convenience 20 patients, 10 male and 10 female, both gender, between 45 and 73 years old, admitted to the Hospital Ana Neri, who underwent coronary angiography (CATE). All laboratory measurements were performed before and after CATE. Results: were significant increase in lipase activity and decreased concentration of triglycerides after CATE, in the overall analysis and stratified by sex (p<0.05, paired t test). The HDL-C/apoA ratio increased significantly after CATE, since the LDL-C/apoB ratio has not increased or decreased in the general analysis, and stratified by gender. While TG/HDL-C cardiovascular risk ratio decreased significantly, ApoB/apoA increased significantly in the overall analysis, and stratified by sex after CATE. The correlation analysis had different behaviors, and the statistic significance found, were dependent of the group analyzed (generally male and female). The concentration of non-HDL-C, similar to the determination of haptoglobin, had a significant decrease in the overall analysis and in males after CATE (p<0.05, paired t-test), the female group do not show significance. The free cholesterol and phospholipids incorporation rates were not significant after the CATE. Conclusion: The administration of in bolus sodium heparin interferes in lipoprotein particles remodeling, by evidences from risk ratios variations, such as HDL-C/apoA, and TG/HDL-C. The percentage of phospholipids and free cholesterol incorporation in HDL shows sex influences, which makes it relevant to the obtained results. The use of hazard ratios and their correlations were better surrogate markers at these casuistic of cardiovascular disease than when serum markers of lipid profile were evaluated alone.

"Splintered and a Great Silence": The Production of Return to the Upright Position by Caridad Svich

Brewer, Catherine (Cate) 06 April 2009 (has links)
Like the Tribute in Light that grew phoenix-like from the ashes of the broken hearts of the artists who created it, Return to the Upright Position is a beautiful on-line collaboration amongst fourteen artists in the six months following 9/11. Conceived and edited by Caridad Svich, the play is moving and delicate and instantly brings us back to those moments when American history and sentiment were forever changed. Demoralized, terrorized, afraid, and alone, our country dragged its shocked and weary carcass from the ash, and pulled itself back up again. That is after all the American way, pulling yourself up by your bootstraps, continuing to believe in a better, brighter future, in hope and possibility; returning to the upright position.

Big Dyke Energy? : Commodification and Queer Female Meaning-Making in the Reception of Ocean’s 8 (Gary Ross, 2018)

Fransen, Esmé January 2020 (has links)
In a media landscape that continues to be characterized by heteronormativity, queer female audiences are continuously finding ways to make popular texts their own. Previous scholarship on queer female reception has largely approached queer meaning-making as a text-audience relationship, a perspective which disregards the position of films as commodities surrounded by an extensive promotional network. This thesis investigates the role of commodification in the process of queer meaning-making in popular film through a reception study of the film Ocean’s 8 (Gary Ross, 2018). Using a netnographic method that places social media reception in dialogue with the film and its promotional materials, it challenges the idea that queer meaning is always either embedded in the film text or brought in by the audience “(in)appropriating” the text. Rather, the film and its promotional context create an ambiguity that allows queer readings to flow freely, and actively interacts with a pre-existing Cate Blanchett-as-lesbian fantasy amongst audiences to steer those readings in particular directions. Queer female meaning-making, then, is far from a one-directional action, but rather a complex and constant renegotiation of queerness between commercial actors and audiences alike.

Примена ГИС-а у картографској генерализацији категоријских карата / Primena GIS-a u kartografskoj generalizaciji kategorijskih karata / Cartographic generalization of categorical maps using GIS

Đorđević Milan 11 July 2016 (has links)
<p>Аутоматизована картографска генерализација је од великог значаја у картографији, а правих решења још увек нема. Картографска ге&shy; нерализација полигона и категоријских карата представља веома комплексан проблем, а предложена решења налазе се углавном на концептуалном нивоу. Метода представљена у овој докторској ди&shy;сертацији представља општи приступ аутоматизованој картограф&shy;ској генерализацији категоријских карата применом ГИС софтвера. Као резултат смањења размера, неки од полигона postaju исувише мали да би били приказани у циљаном размеру тако да се морају уклонити, а њихово место ће заузети нека друга појава. Највећи изазов представља смањење семантичких грешака и минимизирање промене удела класа полигона тако да карта више одговара реалности на терену. То је остварено груписањем полигона исте класе, тако што се врши њихово измештање и стапање. На овај начин,одређени број малих полигона који би били елиминисани постају полигони са довољном површином. Други начин&nbsp;&nbsp; мањења грешака је стапање полигона, који имају недовољну површину, са већим полигонима који су им тематски слични. Такође је представљена и метода за&nbsp; откривање и елиминисање уских делова полигона. Све ове методе моrу бити искоришћене за израду било које категориј&shy;ске карте (нпр. климатске, педолошке, карте употребе земљишта, земљишног покривача, геолошке карте итд.) на основу дигиталног модела предела. Посебан софтвер је развијен за измештање градив&shy;них ћелија полигона ипи прецизније њихових центара. Додатни програм је&nbsp; аправљен за решавање проблема уских коридора код полигона. Модел&nbsp;&nbsp; удруживања је направљен у QGIS-y, а модел ста&shy;пања у PostGIS-y, слободном&nbsp;&nbsp; софтверу, отвореног кода. Резултати показују да је изабрани приступ успешан.</p> / <p>Automatizovana kartografska generalizacija je od velikog značaja u kartografiji, a pravih rešenja još uvek nema.
