    Hydrocarbons are widely spread in ecosystems and especially persistent under anoxic conditions. Still, certain bacteria are capable to degrade hydrocarbons anaerobically, but their ecology is poorly understood. In this thesis, tools to investigate these degrader communities are developed and extended based on PCR detection, fingerprinting and also pyrosequencing of fumarate-adding enzymes, which are key to anaerobic hydrocarbon degradation. These are employed to unravel the diversity and structure of degrader communities in distinct contaminated terrestrial and marine environments, identifying several novel degrader lineages and monitoring their dynamics in impacted systems.Kohlenwasserstoffe sind weitverbreitet und besonders beständig unter anoxischen Bedingungen. Bestimmte Bakterien sind jedoch in der Lage Kohlenwasserstoffe anaerob abzubauen, ihre Ökologie ist aber wenig bekannt. Hier werden Werkzeuge zur Untersuchung dieser Abbauergemeinschaften entwickelt, die auf PCR-Nachweise, Fingerprinting- und Pyrosequencing-Methoden für den anaeroben Abbau von Kohlenwasserstoffen wesentlichen Fumarat-addierende Enzymen basieren. Diese werden zur Untersuchung der Diversität und Struktur der Abbauergemeinschaften in verschiedenen kontaminierten Ökosystemen angewendet

    “Ornamented farm” of Count Frederick William von Reden in Bukowiec as a Modern Agricultural Farm in Silesia. Specifity of Silesian Agricultural Economy on the Example of Bukowiec

    Count Frederick William von Reden is mostly known as the founder of Upper Silesian industries based on the development of iron foundry and coal mining, whereas he was also engaged in the implementation of a certain agricultural reform in Prussia. While visiting Great Britain he became interested in landscape gardening. Shortly before he was granted the title of Count, he had purchased a large estate in Bukowiec in Silesia which he then turned into a modern profitbringing agricultural enterprise. He commissioned an architect to rebuild his newly bought manor house as well as to construct new stables, barns and outhouses. He also hired gardeners to create a landscape garden ornamented with picturesque huts, some glass houses and a tea pavilion. After his death in 1815 his widow Countess Frederick von Reden inherited the farm land. She continued the work initiated by her husband almost till the end of her life in 1854. The author of the paper tries to reconstruct the process of transformation of an old-type manor estate into a modern ornamented farm.Hrabia Fryderyk Wilhelm von Reden jest znany przede wszystkim jako założyciel przemysłu górnośląskiego, bazującego na hutnictwie żelaza i wydobyciu węgla, tymczasem był on także zaangażowany w przeprowadzenie pewnego rodzaju reformy agrarnej w Prusach. Przebywając w Wielkiej Brytanii, zainteresował się zakładaniem parków krajobrazowych. Na krótko przed uzyskaniem hrabiowskiego tytułu nabył rozległe dobra w Bukowcu na Śląsku, które przekształcił w nowoczesne i dochodowe gospodarstwo rolne. Zatrudnił architekta w celu przebudowy nowo nabytego dworu oraz wystawienia nowych budynków folwarcznych. Wynajął też ogrodników, by założyć park krajobrazowy, ozdobiony malowniczymi chatami, szklarniami i pawilonem herbacianym. Po jego śmierci w 1815 roku dziedziczką dóbr została jego żona hrabina Fryderyka von Reden. Kontynuowała ona dzieło zainicjowane przez hrabiego niemal aż do swej śmierci w 1854 roku. Autorka artykułu usiłuje zrekonstruować proces przekształcania dawnego majątku w nowoczesną farmę ozdobną

    Cello techniques and performing practices in the nineteenth and early twentieth centuries

    No full text
    This thesis comprises a study of cello performance practices throughout the nineteenth century and into the early decades of the twentieth. It is organised in terms of the increasing complexity of the concepts which it examines, as they are to be found in printed and manuscript music, instrumental methods and larger treatises, early recordings, concert reviews and pictures. Basic posture is considered along with different ways of holding the bow. The development of the tail-pin shows that even when it was widely used, the older posture was still referred to as a model. Some implications for tone quality and tonal projection are considered in the light of the shape of the arms. Some connections between the cellist's posture and that recommended by etiquette books are explored. The functionality of the left hand and arm, and the development of modem scale fingerings, show that there was a considerable period of overlap between newer and older practices, with modern scale fingerings evolving over a long period of time. Similarly, views on the function of the right wrist in bowing are shown to change gradually, moving towards a more active upper arm movement with less extreme flexibility of the wrist. Two central expressive techniques especially associated with string playing arc considered in the context of the cello, namely vibrato and portamento. These topics are examined in the light of written indications in music, recommendations in cello treatises, and the practices evidenced in early recordings. The sources for this study can be brought into an overall framework of a constant dialogue between `theory', as expressed in verbal instructions to the learner, or general a priori reflections about the cello, and `practice', manifested in performing editions and early recordings, or in individual acts of reception. A wide divergence is noted, both between theory and practice in general, and in terms of different styles of playing observable at any one time. It is suggested that tensions between practice and critical disapproval can be resolved in terms of Lacanian discourse. Several test cases are used in order to compare several different recordings of the same works. The question of the musical character of the cello is discussed in terms of widespread assumptions about its gendered identity. A wide range of sources suggest that this moved from a straightforwardly `masculine' identity expressed through a controlling, elevated eloquence to a less clearly defined one, incorporating the 'feminine', with a greater stress on uninhibited emotional expression. Some performance implications for this change of view are pursued with respect to specific repertoires. Broad conclusions stress the importance of the diversity of performance practices as opposed to unifying generalisations

    Duell an der Havel: Fritz von Unruh’s depiction of eighteenth-century Prussian-American relations

    No full text
    In his play Duell an der Havel (1954), the German playwright Fritz von Unruh took the liberty to imagine a fictional encounter between historic figures like Frederick the Great of Prussia and President George Washington. In his play, Unruh attempts a difficult mediation between opposing models of Enlightenment governance and the opposition of freedom and duty. Although historic events in Unruh’s play are completely invented and staged, the author argues that the play holds up as a way of thinking about the complex history of the transatlantic relationship between Germany and the United States, from Washington and Fredrick the Great to Trump and Merkel.

    Poems Gedichte by von Frederick Philip Grove Felix Paul Greve

    No full text
    This comprehensive edition of Frederick Philip Grove's poetry comprises 122 poems stemming largely from his archives at the University of Manitoba. The majority reflect his Canadian creations (75). Most of these are based on a typescript collection entitled Poems: In Memoriam Phyllis May Grove (63 poems), but there are many other manuscript and typed sources as well. Only a selection of twenty-one poems from the In Memoriam collection were ever published under the title From the Dirge in Canadian Forum (April, 1932). The probable date of composition lies between 1927 and 1932, the plan of devoting a cycle to the memory of his only child having originated with her tragic death at the age of twelve in July 20, 1927. One-third of the corpus (41 poems) are by the author and prolific translator Felix Paul Greve, who disappeared from his native Germany in September, 1909, and who is believed to have assumed a new identity as Grove when he came to Manitoba in December, 1912. While more than half of his poetry (23) was published as Wanderungen in 1902, this edition also includes fifteen poems which were recently discovered by the editor. Central in position and importance, there are six German manuscript poems by Grove which are extant in his archives. Their thematic, stylistic and formal affinity with Greve's neo-romantic poetry allows for a perfect juncture of the German and the English parts of this edition, and they furthermore confirm the (not totally uncontested) connection between the two authors, since one of Grove's poems was published by Greve in 1907. The edition is preceded by a substantial introduction, and supplemented with a critical apparatus which includes a concordance to the German and English poetry, an index of first lines, convenient tables, and an extensive bibliography
