The heights of meteors were obtained from measurements by SKiYMET meteor radar system at Cachoeira Paulista (22.7 ° S, 45.0 ° W). The data used include measurements taken from March 1999 to July 2006 and from September 2007 to October 2008. The echo of the reach and the zenith angle with respect to each radar echo are used for the heights of occurrence of meteors. The maximum height of daily occurrence was obtained from the Gaussian distribution through vertical adjustment. The series of height data of peak occurrence of meteors was subjected to multiple linear regression analysis to investigate the trend and possible variations induced by solar activity. The results showed a downward trend of approximately 68 m / year at the time of maximum occurrence of meteor and 447 m / 100sfu using monthly data after removal of the solar effect, resulting in a decrease in the peak height of approximately 248 m for all observation period after the time trend removal. Considering only the period of decline of the solar cycle (2002-2008) the decline was approximately 1054 m using monthly data in the analysis. The decrease of the meteors occurrence height can be attributed, in part, the effects of solar activity. Knowing that the atmosphere expands with the growth of solar activity the neutral density shows a downward trend over time. / Neste trabalho, dados das alturas de máxima ocorrência de ecos meteóricos foram usados para investigar uma possível relação entre as variações na altura dos meteoros e fluxo solar em baixas latitudes, durante o ciclo solar 23. As alturas dos meteoros foram obtidos a partir das medidas por radar meteórico SKiYMET em Cachoeira Paulista (22,7°S, 45,0°O). Os dados utilizados incluem as medidas realizadas de março de 1999 a julho de 2006 e de setembro de 2007 a outubro de 2008. O alcance do eco e o ângulo zenital referente a cada eco do radar são usados para obter as alturas de ocorrência dos meteoros. A altura de máxima ocorrência diária foi obtida a partir da distribuição vertical através de ajuste Gaussiano. A série de dados da altura do pico de ocorrência de meteoros foi submetida a análise de regressão linear múltipla para investigar a tendência e possíveis variações induzidas pela atividade solar. Os resultados indicam uma tendência de queda de aproximadamente 68 m/ano na altura de ocorrência máxima dos meteoros e de 447 m/100sfu utilizando os dados mensais após remoção do efeito solar, acarretando numa diminuição da altura do pico de aproximadamente 248 m para todo o período observado após remoção da tendência do tempo. Considerando apenas o período de declínio do ciclo solar (de 2002 a 2008) a queda foi de aproximadamente 1054 m utilizando nas análises os dados mensais. O decréscimo da altura de ocorrência dos meteoros pode ser atribuído, em parte, a efeitos da atividade solar. Sabendo que a atmosfera se expande com o crescimento da atividade solar a densidade neutra apresenta uma tendência decrescente ao longo do tempo.

Cette thèse propose le développement d'une méthodologie permettant l'obtention des débits distribués dans le bassin amazonien à partir des hauteurs d'eau altimétriques. Au vu des derniers travaux et des avancées récentes dans ce domaine, ce travail a particulièrement porté sur les informations connexes pouvant être extraites des résultats. Nous avons utilisé des relations hauteur-débit basées sur l'équation de Manning et optimisées au travers d'un algorithme d'optimisation globale correctement paramétré. Les hauteurs d'eau ont été obtenues à partir des hauteurs altimétriques fournies par les missions ENVISAT et Jason-2, et les débits ont été estimés sur la même période par le modèle MGB-IPH sur l'ensemble du bassin. L'utilisation de l'algorithme d'optimisation SCEM-UA a permis de définir des intervalles a priori pour les paramètres ajustables ainsi que de gérer les notions d'erreur dans les données d'entrée, et d'incertitude dans les paramètres de sortie. Une des productions de ce travail est la construction d'une base de données d'un millier de courbes de tarage avec les intervalles de confiance associés. La validité spatiale de ces courbes de tarage a pu être vérifiée par comparaison avec les débits du modèle ainsi que les débits in situ disponibles. Leur stabilité dans le temps, quant à elle, a été confirmée par notre capacité à estimer des débits cohérents avec des informations de hauteurs d'eau provenant d'autres missions et d'autres périodes que celle à partir de laquelle les relations hauteur-débit avaient été estimées. Ce travail a également mis en évidence, par validation in situ, modélisation inverse et analyse de cas tests sur des rivières synthétiques, la capacité de la méthodologie proposée à identifier les caractéristiques géomorphologiques des sections étudiées. / This thesis proposes the development of a methodology that aims to obtain distributed discharges in the Amazon basin based on satellite altimetry data and modeled discharges. Given recent works and advances, this work focused particularly on the information that can be inferred from the resulting relationships. We used stage-discharge relationships based on Manning's equation that were optimized through a global optimization algorithm adequately configured. Altimetry data was taken from ENVISAT and Jason-2 missions and discharges were estimated for an overlapping period by the MGB-IPH model. A-priori intervals were defined into the SCEM-UA scheme for each optimization's parameter, and the algorithm allowed us to deal with input errors and output uncertainties. We produced a thousand gross database of rating curves and associated confidence intervals. Hydrological coherence was proved by validation with both modeled and in situ discharges. Successfully using an ENVISAT-based RC with Jason-2 data to estimate discharge at a cross-over, we proved that rating curves are not mission-dependent and can be used with any incoming water height data. Geomorphological characteristics of studied section given by our rating curves were validated through comparison with in situ data, inverse modeling of a braided river reach and synthetic rivers test cases.

Ce mémoire se consacre à une étude de l'infantile et de la pulsion de mort comme constituants d'une écriture du Mal dans Wuthering Heights (1847), l'unique roman de l'écrivaine anglaise Emily Brontë (1818-1848). Cette analyse s'inspire en premier lieu des travaux de Sigmund Freud sur les pulsions, le rêve et l'infantile. Le récit de Wuthering Heights s'articule autour des familles Earnshaw et Linton. L'arrivée de Heathcliff, un jeune orphelin, bouleversera la vie des membres de la famille Earnshaw. Catherine Earnshaw et de Heathcliff, élevés comme frère et soeur, mais liés dans leur jeunesse par une passion absolue et sans concession jusque dans la mort, subiront l'épreuve du temps à la sortie de l'enfance. Le roman présente des motifs récurrents qui contribuent à l'élaboration d'une expérience du Mal singulière. Les descriptions poétiques, la souffrance des personnages, la violence de l'écriture, les figures de la mort et l'hostilité des lieux du récit se donnent à lire comme les figures d'une répétition ou la reprise des éléments d'une histoire passée, moteur de la conception narrative du désastre et du tragique. L'étude du roman suppose l'exploration de cet univers inspiré par la violence, la cruauté, mais aussi la passion que suscite le désir d'absolu attaché à ce passé. Wuthering Heights est un récit dans lequel se mêlent, se démêlent, se confondent et se confrontent des mécanismes régis par des pulsions à la fois autodestructrices et libératrices. Ce mémoire analysera le roman dans sa structure narrative et son énonciation afin de rendre compte du caractère absolument tragique de la passion des protagonistes, de comprendre les mécanismes cruels de la narration et de démontrer la vision du Mal essentielle et universelle du récit. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Emily Brontë, Wuthering heights, Pulsion de mort, Infantile, Rêve, Mal, Tragique, Absolu.

Syftet är att fastställa gemensamma drag och paralleller, som återfinns i dels keltiska myter/keltiska texter och dels i Wuthering Heights, för att sedan kunna diskutera hur dessa gemensamma drag möter och interagerar med varandra.Resultat: Jag har funnit att det i Wuthering Heights’ ramberättelse återfinns gemensamma drag och paralleller, mellan voyage-genrerna immram & echtrae och Wuthering Heights. I Wuthering Heights ’ kärnberättelse har jag funnit gemensamma drag och paralleller mellan berättelserna hämtade från Leabhar Gabhála Éireann och Wuthering Heights (samtligt mytologiskt material är hämtat ur den mytologiska cykeln). I diskussionen om det innehållsliga mötet, kommer jag fram till att Mr. Lockwood förändrats i och genom sin resa. Jag finner också att Wuthering Heights förändrats i sitt möte med Mr. Lockwood. Lägger man sedan det mytiska filtret uppe på det innehållsliga mötet kan man tolka in ett att kulturellt möte mellan det keltiska/gamla och det europeiskt-kristna/nya som en fruktbar förening, där ingen av parterna är att ringakta. Genom att låta polariteter som dåtid/nutid, hedniskt/kristet och ödemark/civilisation beblanda sig med varandra, både textmässigt strukturellt sker en sammansmältning. Detta är något som ligger helt i linje med den mytologiska cykelns världsuppfattning, där element från vår värld beblandas med element från the Otherworld.

The initial research into the phenomenon of nuclear fission was done at university laboratories in Europe on the eve of the Second World War. This war led to the development of the first nuclear weapons. After the war, many nations wanted access to both the weapons and the source of cheap power that the process of nuclear fission provided. Australia was one such nation. -- The Australian Government wanted nuclear energy to help develop the dry interior of the continent. There were many in Government who also wanted nuclear weapons. This work focuses on the Australian pursuit of nuclear energy for peaceful uses. The achieve this aim an organisation was established which would train scientists and engineers in nuclear science and technology. This organisation, the Australian Atomic Energy Commission, is the subject of this thesis. -- This work will examine the political influences that governed the Commission in its function and scientific research paths. Specifically, it will examine how successive governments caused the Commission to cancel projects, change the direction of its research, attempted (on several occasions) to amalgamate the Commission with the CSIRO, forcing the organisation into uranium mining and finally abolishing it and replacing it with a new organisation, the Australian Nuclear Science and Technology Organisation. Government interference would continue with this new organisation which had its entire board dismissed in 1993. -- The Commission was essentially a scientific and engineering organisation and hence this thesis will also consider a number of projects with which the Commission was involved such as the Beryllium Project, uranium exploration and mining, the uranium enrichment programs, the purchase of two nuclear reactors, the Synroc project, and the ill-fated Jervis Bay power reactor project. Other projects which were started in the early days of the Commission, the neutron diffraction work and the isotope production projects, will be mentioned in passing. Both these projects require a more detailed appraisal than is possible in this thesis. / Mode of access: World Wide Web. / viii, 278 p. ill
