Dans cette thèse, nous nous intéressons à l'étude de l'arithmétique (le principe de Hasse, l'approximation faible, et l'obstruction de Brauer-Manin) des zéro-cycles sur les variétés algébriques définies sur des corps de nombres. Nous introduisons la notion de sous-ensemble hilbertien généralisé. En utilisant la méthode de fibration, nous démontrons que l'obstruction de Brauer-Manin est la seule au principe de Hasse et à l'approximation faible pour les zéro-cycles de degré 1; et établissons l'exactitude d'une suite de type global-local concernant les groupes de Chow des zéro-cycles, pour certaines variétés qui admettent une structure de fibration au-dessus d'une courbe lisse ou au-dessus de l'espace projectif, où les hypothèses arithmétiques sont posées seulement sur les fibres au-dessus d'un sous-ensemble hilbertien généralisé.De plus, nous relions l'arithmétique des points rationnels et l'arithmétique des zérocycles de degré 1 sur les variétés géométriquement rationnellement connexes. Comme application, nous trouvons que l'obstruction de Brauer-Manin est la seule au principe de Hasse et à l'approximation faible pour les zéro-cycles de degré 1 sur- les espaces homogènes d'un groupe algébrique linéaire à stabilisateur connexe,- certains fibrés en surfaces de Châtelet au-dessus d'une courbe lisse ou au-dessus de l'espace projectif (en particulier, les solides de Poonen).

En utilisant la méthode de fibration, nous démontrons que l’obstruction de Brauer-Manin est la seule au principe de Hasse et à l’approximation faible pour les zéro-cycles de degré 1; et établissons l’exactitude d’une suite de type global-local concernant les groupes de Chow des zéro-cycles, pour certaines variétés qui admettent une structure de fibration au-dessus d’une courbe lisse ou au-dessus de l’espace projectif, où les hypothèses arithmétiques sont posées seulement sur les fibres au-dessus d’un sous-ensemble hilbertien généralisé.De plus, nous relions l’arithmétique des points rationnels et l’arithmétique des zérocycles de degré 1 sur les variétés géométriquement rationnellement connexes.

D. thesis studies the arithmetic properties (the Hasse principle, the weak approximation, and the Brauer-Manin obstruction) for zero-cycles on algebraic varieties defined over number fields. We introduce the notion of generalized Hilbertian subset. By using the fibration method, we prove that the Brauer-Manin obstruction is the only obstruction tothe Hasse principle and to the weak approximation for zero-cycles of degree 1; and establish the exactness of a sequence of global-local type concerning Chow groups of zero-cycles, for certain varieties which admit a fibration structure overa smooth curve or over the projective space, where the arithmetic hypotheses are only posed on the fibers over a generalized Hilbertian subset. Moreover, we relate the arithmetic of rational points and that of zero-cycles of degree 1 on geometrically rationally connected varieties. As an application, we find that the Brauer-Manin obstruction is the only obstruction to the Hasse principle and to the weak approximation for zero-cycles of degree 1 on- homogeneous spaces of a linear algebraic group with connected stabilizer,- certain varieties fibered into Chatelet surfaces over a smooth curve or over the projective space (in particular, Poonen's threefolds).

Este trabalho tem como objeto de estudo a investigação da poética de Fiama Hasse Pais Brandão buscando entender o que é fala perfeita para a Autora. Analisamos minuciosamente o poema Teoria da Realidade tratando-a por tu, que é toda uma poética, e o relacionamos com sua obra, demonstrando assim uma coerência em seu projeto poético. O poema analisado faz parte da série Poéticas, do livro Cenas Vivas de 2000. Nesse poema há um desdobramento do sujeito poético que persegue sua voz desde seus balbucios. Podemos dizer que o sujeito da enunciação nos conta como sua voz poética apareceu, desenvolveu, adquiriu a fala perfeita e a ofereceu aos leitores. Desde a publicação de Morfismos, em 1961, que a Autora preocupou-se em resgatar a língua da estreiteza de seu uso comum e em dar autonomia à linguagem, buscando o que chamou de poesia/ substantivo, assim se filiando à tradição da modernidade e especificamente a Mallarmé. Seus poemas são testemunhos de tudo o que foi escrito e lido por ela, desde as grandes epopeias e a Bíblia, à tradição anglo-germânica, aos grandes poetas americanos e à tradição portuguesa. Fizemos um percurso em sua obra perseguindo poemas que são poéticas, ou seja, que o tema é a própria poesia para descobrir como se dá a visão e o conhecimento que Fiama tem do real e do poético. Constatamos que fez uma opção pela realidade. A matéria poética de Fiama pertence à terra, há uma preocupação em desvendar o real. Podemos constatar essas questões, a partir da nossa leitura dos poemas de Obra Breve Poesia Reunida. Selecionamos um percurso poético que desaguou em Teoria da Realidade tratando-a por tu, o que nos mostrou a intimidade que adquiriu com a realidade, além de nos revelar como sua voz poética desabrochou. / This study has its object of research the poetry of Fiama Hasse Pais Brandão, attempting the understanding of what the perfect speech means to the author herself. Detailed examination of the poem Teoria da Realidade tratando-a por tu (The Theory or Reality getting familiar with it), reflects the complete author´s poetic, embracing Fiama´s work as a whole. The poem analyzed makes part of the series Poetics (Poetics) from the Cenas Vivas (Living Scenes) book dated from the year 2000. There is in this poem the unfolded poetic subject that chases her muttering voice. We can say the enunciation subject tells us how the poetic voice had emerged, developed, acquiring the perfect speech thus offering it at last to its readers. Since the publication of Morfismos (Morphisms) in 1961, the Author worries about the language narrowness, rescuing from its ordinary use. Giving autonomy to it as well as searching what she had called the poetry/noun. This way Fiama´s poetry filiation relies on the modern tradition and specifically in Mallarmé. Her poems witness all the things that has been written and read by her. From great epics to the Bible, the Anglo-Germanic tradition to the great American poets also including in this list the Portuguese tradition as well. The path throughout her work has chased poems that are poetic, in other words, that the theme is the poetry itself, revealing the envisioning and the knowledge Fiama has from reality as well as poetry. It has been detected she opted for reality. The poetic material for her, belongs to the Earth where there is a concern to unveil what is real. These matters have been attested based on the reading of the poems of the Obra Breve Poesia Reunida (Brief Works). The poetic path selected ended up in the Teoria da Realidade tratando-a por tu (Theory of Reality- getting familiar with it), this has exposed us the intimacy that she has gained with reality, revealing at same the time how her poetic voice blossomed.

Primenom multivarijantnih statističkih metoda analizirani su korelacioni odnosi između ključnih fizičko-hemijskih parametara i koncentracionih nivoa rezidula katjona teških, lakih i semimetala. Faktorskom analizom (PCA) i klaster analizom sa dendogramima tumačeni, analizirani i diskutovani su dobijeni rezultati. Za optimalnog uočavanja korelacionih odnosa primenjeno je unapređeno rangiranje određenih skupova podataka (interkorelacije ključnih fizičko-hemijskih parametara i rezidua katjona metala) i grafički prikazanih Haseovih dijagrama primenom DART softvera (Decision Analysis by Ranking Techniques) za definisani model procene uticaja raspodele katjona toksičnih metala u heterogenom sistemu tečno/čvrsto na kvalitet površinskih voda.</p> / <p>In the doctoral thesis are evaluated inter correlational results of key physicochemical parameters and metal cations in surface water of Danube, Tisa (on three selected representative sampling points) and canal Danube-Tisa-Danube (on two sampling sites).

Bis auf wenige, kurze Zeitabschnitte gehört die Dresdner Hof- (heute Staats-)kapelle seit Jahrhunderten zur Spitzengruppe bezüglich der europäischen Orchesterentwicklung. Ihr Repertoire und dessen Überlieferung sind somit von musikhistorischer Relevanz, dabei aber bislang nicht vollständig erschlossen und infolgedessen von Forschung und Praxis unzureichend wahrgenommen. Hier Lücken zu schließen, ist das Ziel der vorliegenden Publikation. Die als „Drei Studien“ bezeichneten Arbeiten widmen sich der Entstehungs- und Sammlungsgeschichte einer Auswahl von historischem Musiziergut der Kapelle, das sich in der heutigen SLUB befindet. Da mit zeitlichem Abstand entstanden, repräsentieren sie unterschiedliche Erkenntnisphasen der Autorin. Die 1999 bzw. 2002 als Begleittexte zu zwei als Sondereditionen von RISM/A/II veröffentlichten CD-ROM-Katalogen im Druck erschienenen Studien I und II sind im Handel nicht mehr greifbar, so daß ihre digitale Herausgabe wünschenswert war, zumal diese auch die Möglichkeit bot, Korrekturen und Ergänzungen einzuarbeiten. Der Text der der Dresdner Hasse-Sammlung gewidmeten Studie I wird z.B. erweitert durch ein Kapitel zu den originalen Einbänden dieser Sammlung. Zum Text der das Dresdner Opernarchiv behandelnden Studie II wurden vor allem fehlende Register hinzugefügt. Ein Zentralthema beider Arbeiten bilden die Untersuchungen zu den Schreibern der Musikalien. Diese Untersuchungen werden in Studie III erheblich erweitert und zu neuen Ergebnissen geführt. Erstmals liegt nun für die Zeit von 1720 bis 1850 der Umriß einer Geschichte des Dresdner Hofnotistenamtes vor, wobei diesbezügliche Forschungsergebnisse anderer Autoren eingearbeitet sind. Neue Einblicke in die Dresdner höfische Musikgeschichte ließen sich für zwei ihrer repräsentativsten Überlieferungskomplexe gewinnen: die Hasse-Sammlung umfaßt Werke aller Gattungen, die während Hasses 30jährigem Wirken (ab 1731/34) und noch danach für die Musikpflege Bedeutung hatten; das Opern-Archiv schließt auf dem Gebiet der italienischen und später der deutschsprachigen Oper zeitlich an und umfaßt den Fundus von 1765 bis nach 1900. Zu beiden Komplexen sind die Titelaufnahmen in der Datenbank RISM/A/II mit dem Fundortsigel „D Dl“ sowie eine kleine Titelzahl mit Sigel „D Ds“ vorhanden und ergänzend zu den Studien I und II zu benutzen. Hinsichtlich der Schreiber-Bestimmungen sei aber generell auf Studie III mit ihren Abbildungen verwiesen: sie repräsentieren den aktuellen Erkenntnisstand, der in den älteren Arbeiten, ausgenommen die Abbildungen zu ihnen, nicht nachgebessert wurde. Die Abbildungen in ihrer Gesamtheit, nicht zuletzt jene, die den am Dresdner Hof verwendeten Einbänden gelten, sind über die spezielle Dresdner Thematik hinaus interessant für viele europäische Bibliotheken, die seit dem 18. oder 19. Jahrhundert Musikhandschriften Dresdner Ursprungs besitzen, diesen Ursprung aber nicht mehr oder nur ungenau kennen. Der Überlieferungswert der Musikalien, deren Dresdner Herkunft anhand der Abbildungen deutlich wird, dürfte sich in den meisten Fällen gegenüber bisheriger Einschätzung erhöhen. / Except for short lapses of time, the Dresden Court Orchestra (today’s Saechsische Staatskapelle Dresden) has for centuries belonged to the elite regarding the European orchestral development. As a result its repertoire and the written tradition of this repertoire are relevant to music history, but so far not completely recorded, and thus inadequately considered in research and practice. The intent of this publication is to close respective gaps. The individual contributions, designated as “Three Studies,” are dedicated to the history of a selection of the orchestra’s early music material kept by the present Saxon State and University Library (SLUB) in Dresden. As the author conceived the articles in different time periods, they represent differing phases of perception. Studies I and II, which were published in 1999 and 2002 as accompanying texts to two CD-ROM catalogs released as special editions to RISM’s catalog series A/II “Music Manuscripts after 1600,” are no longer available on the market. Therefore a digital edition was desirable, especially as it offered the possibility of integrating corrections and supplements. Study I, dedicated to the Dresden Hasse Collection, is for example supplemented by a chapter on the original bindings of the music manuscripts. The study II treating the Dresden Opera Archive was mainly complemented by additional indexes. Scribal research is a central theme of both studies. Considerably augmented in Study III, this research leads to new conclusions. For the first time the history of the Dresden court office of music scribe (to be precise: the period from 1720 to 1850) has been outlined, thereby integrating pertinent research results of other authors. New perceptions of the Dresden court music history have been achieved relating to two of its most representative aggregations of music material: The Hasse Collection comprises works of all genres significant for the practice of music during Hasse’s thirty year term of office (from 1731/34 on) and afterwards; the Opera Archive joins in the area of Italian and later German opera and includes the specific music from 1765 to after 1900. Supplementing Studies I and II, the catalog entries for both collections – library siglum “D Dl” – as well as a small number of entries with siglum “D Ds” are available in the RISM A/II database. In regard to the identification of scribes, Study III with its illustrations is pertinent: they represent the current level of perception, whereas the state of knowledge in the two older studies was not corrected, illustrations excepted. The illustrations in their entirety, not least those relating to the Dresden court bindings, are of interest beyond their Dresden-specific aspects for many European libraries which have acquired music manuscripts since the 18th or 19th centuries but are no longer or only imperfectly aware of their origin. The source value of the music manuscripts whose Dresden provenance is revealed by the illustrations should increase in most cases beyond their former evaluation.
