Der Herausforderung durch Shakespeares Bühnenwerke, so scheint es, hat sich kaum ein großer Opernkomponist entziehen können. Die immense Attraktivität seiner Dramen geht indessen einher mit ihrer ebenso großen Widerständigkeit: Shakespeares Werke setzen der "Veroperung" offenbar einiges entgegen. Davon zeugt die geringe Zahl musikdramatischer Repertoirestücke, die auf Shakespeare basieren, und davon zeugen die Probleme, die viele Komponisten und Librettisten mit ihren Shakespeare-Projekten hatten. Vor allem die großen Charaktertragödien waren schwer zu meistern: Verdi nahm sein lebenslanges Lear-Vorhaben mit ins Grab, Felix Mendelssohn-Bartholdy und Robert Schumann, Michail Glinka und Georges Bizet scheiterten an Hamlet. Eröffnet wird diese Reihe ambitionierter, aber unausgeführter Shakespeare-Opern durch Ludwig van Beethovens Macbeth-Skizze. Das fragmentarische Libretto zu Beethovens Macbeth, das die Forschung bislang noch nicht näher untersucht hat, ist der Zielpunkt des vorliegenden Beitrags (III). Um diesen Entwurf historisch zu würdigen, wird zunächst die musikalische Rezeption von Shakespeares Dramen im Deutschland des späten 18. Jahrhunderts skizziert. Leitend sind dabei im wesentlichen zwei Fragen. Zum einen: Wie stark hat die Shakespeare-Begeisterung seit dem Sturm und Drang auf die deutsche Librettistik ausgestrahlt? Und zum anderen: Inwiefern fördert die musikdramatische Shakespeare-Rezeption die Etablierung einer "großen deutschen Oper"? Seit dem ‘Sturm und Drang’ werden Shakespeares Dramen in Deutschland auf zweifache Weise musikalisch rezipiert. Beide Rezeptionsmodi überschneiden sich vielfach und verlaufen historisch parallel, sind aber systematisch durchaus zu trennen: Strukturell abgrenzen läßt sich die musikalische Rezeption auf dem Sprechtheater (I), also in Gestalt von Inzidenz-, Schauspiel- und Bühnenmusiken, von der eigentlichen ‘Veroperung’ von Shakespeare-Dramen, also der Rezeption auf dem Musiktheater (II).
Die "Werther"-Allusionen in zwei repräsentativen Dramen des Naturalismus – Arno Holz’ und Johannes Schlafs "Familie Selicke" und Gerhart Hauptmanns "Vor Sonnenaufgang" – dienen zum einen dazu, Milieu und Protagonisten zu charakterisieren und ihre Prägung durch bürgerliche Moralvorstellungen zu illustrieren. Zum anderen zeigt eine intensive Kontextualisierung der punktuellen Anspielungen, dass die naturalistischen Dramatiker damit programmatisch gegen die bürgerliche Goethe-Verehrung der Zeit und die Dominanz traditioneller Kunstanschauungen opponieren, die ihrer sozial-analytischen Dramatik im Wege stand.
Der "grosse Kenner der Deutschen Ottave Rime" : Wielands Autorität bei Tasso-Übersetzern um 1800
(2004)
Ausgehend von einer zentralen Programmschrift romantischer Übersetzungskunst, die vor allem Ariosts "Orlando furioso" gilt, können zunächst Thesen zu Wielands Bedeutung für deutsche Stanzenübertragungen entwickelt werden. Zugleich sind die unterschiedlichen formalen Ansprüche zu bestimmen, die für die Übersetzung Ariosts auf der einen und Tassos auf der anderen Seite erhoben werden. In chronologischer Folge ist sodann Wielands jeweiliger Einfluß auf die Tasso-Übersetzungen seiner Zeit darzustellen und zu untersuchen, ob Wieland auch nach den epochalen Leistungen der Romantiker noch zu den Autoritäten in der Frage einer deutschen Stanze zählt. Vorliegende Studie soll damit eine Phase der deutschsprachigen Stanzendichtung näher bestimmen und einen Beitrag zur ungeschriebenen Geschichte der deutschen Stanze leisten.
The first record of the very rare linyphiid spider Ceraticelus bulbosus (Emerton, 1882) from Germany is presented. Furthermore records of Agroeca dentigera, Agyneta arietans, Bathyphantes setiger, Brommella falcigera, Crustulina sticta, Erigone dentigera, Meioneta mossica, and Pardosa morosa and other rare spiders are reported.
We present the first measurement of fluctuations from event to event in the production of strange particles in collisions of heavy nuclei. The ratio of charged kaons to charged pions is determined for individual central Pb+Pb collisions. After accounting for the fluctuations due to detector resolution and finite number statistics we derive an upper limit on genuine non-statistical fluctuations, perhaps related to a first or second order QCD phase transition. Such fluctuations are shown to be very small.
The preferences to several properties of habitats (4 levels of humidity and light exposure, 7 kinds of habitat structure and 7 types of blotops) are given in form of an ecogramm for 320 species of spiders living In strata near the ground. A simple method for habitat analysis is presented.
In this study, we investigate the interaction of jets with their environment at a microscopic level, which is a key open question in the study of relativistic jets. Using small simulation systems during past research, we initially studied the evolution of both electron–proton and electron–positron relativistic jets containing helical magnetic fields, by focusing on their interactions with an ambient plasma. Here, using larger jet radii, we have performed simulations of global jets containing helical magnetic fields in order to examine how helical magnetic fields affect kinetic instabilities, such as the Weibel instability, the kinetic Kelvin–Helmholtz instability (kKHI) and the mushroom instability (MI). We found that the evolution of global jets strongly depends on the size of the jet radius. For example, phase bunching of jet electrons, in particular in the electron–proton jet, is mixed with a larger jet radius as a result of the more complicated structures of magnetic fields with excited kinetic instabilities. In our simulation, these kinetic instabilities led to new types of instabilities in global jets. In the electron–proton jet simulation, a modified recollimation occurred, and jet electrons were strongly perturbed. In the electron–positron jet simulation, mixed kinetic instabilities occurred early, followed by a turbulence-like structure. Simulations using much larger (and longer) systems are required in order to further thoroughly investigate the evolution of global jets containing helical magnetic fields.
Die ersten Aufzeichnungen für Mecklenburg-Vorpommern, Deutschland, der Spezies Mermessus trilobatus, Parasteatoda Tabulata und Araniella inconspicua werden zur Verfügung gestellt, zusammen mit bemerkenswerten Vorkommen der seltenen Arten Ero tuberculata, Jacksonella falconeri, Philodromus histrio und Oxyopes ramosus.
Zwei Fälle von abweichender epigyner Form in Pardosa palustris (Linnaeus, 1758) werden beschrieben. Charakteristisch ist das Fehlen der hinteren Seitenteile des Septums. Mögliche Ursachen, wie zum Beispiel "Genitalschaden" bei der Paarung oder die Auswirkungen von Parasitenbefall, werden diskutiert.

The particle-in-cell (PIC) method was developed to investigate microscopic phenomena, and with the advances in computing power, newly developed codes have been used for several fields, such as astrophysical, magnetospheric, and solar plasmas. PIC applications have grown extensively, with large computing powers available on supercomputers such as Pleiades and Blue Waters in the US. For astrophysical plasma research, PIC methods have been utilized for several topics, such as reconnection, pulsar dynamics, non-relativistic shocks, relativistic shocks, and relativistic jets. PIC simulations of relativistic jets have been reviewed with emphasis placed on the physics involved in the simulations. This review summarizes PIC simulations, starting with the Weibel instability in slab models of jets, and then focuses on global jet evolution in helical magnetic field geometry. In particular, we address kinetic Kelvin-Helmholtz instabilities and mushroom instabilities.
Die Ökologische Arbeitsgemeinschaft (ÖKO-AG), ein freiwilliger Zusammenschluß naturinteressierter Studenten (vor allem des Fachbereiches Landespflege), hat in den Jahren 1983 und 1984 eine flächendeckende, z.T. quantitative Kartierung der Amphibien und Reptilien der Stadt Höxter begonnen. Wesentliche Zielsetzung neben dem Erfassen der Bestände ist auch, etwas für den Schutz dieser Artengruppen zu tun, stellvertretend für die gesamten Lebensgemeinschaften der Gewässer. Die ersten Ergebnisse, die hiermit vorgestellt werden sollen, basieren auf Kartierungen der potentiellen Laichgewässer für Amphibien, der Kontrolle uns bekannter Amphibienwanderwege und besonders bei den Reptilien auf Zufallsbeobachtungen. Die Bestandserfassung wird in den folgenden Jahren fortgesetzt werden,wobei der Schwerpunkt dann auf mögliche Schutzmaßnahmen und die Erhaltung und Neugestaltung der Lebensräume verlagert wird.
The Changhsingian (Late Permian) Hambast Formation of sections at Baghuk Mountain (Central Iran) has yielded diverse ammonoid assemblages composed of the genera Pseudogastrioceras, Shevyrevites, Arasella, Dzhulfites, Paratirolites, Clivotirolites gen. nov., Esfahanites gen. nov., Alibashites, Lutites gen. nov., Abichites and Stoyanowites. The succession of ammonoid species allows for a subdivision of the rock unit into biozones, which largely correlate with the occurrences in north-western Iran. Three new genera, Clivotirolites Korn & Hairapetian gen. nov., Esfahanites Korn & Hairapetian gen. nov. and Lutites Korn & Hairapetian gen. nov., as well as 19 new species are described: Shevyrevites corrugatus Korn & Hairapetian sp. nov., Arasella falcata Korn & Hairapetian sp. nov., Dzhulfites brevisellatus Korn & Hairapetian sp. nov., Paratirolites rubens Korn & Hairapetian sp. nov., Paratirolites lanceolobatus Korn & Hairapetian sp. nov., Paratirolites robustus Korn & Hairapetian sp. nov., Paratirolites baghukensis Korn & Hairapetian sp. nov., Paratirolites aduncus Korn & Hairapetian sp. nov., Clivotirolites decoratus Korn & Hairapetian gen. et sp. nov., Clivotirolites petilus Korn & Hairapetian gen. et sp. nov., Esfahanites armatus Korn & Hairapetian gen. et sp. nov., Lutites paucis Korn & Hairapetian gen. et sp. nov., Lutites lyriformis Korn & Hairapetian gen. et sp. nov., Lutites profundus Korn & Hairapetian gen. et sp. nov., Lutites alius Korn & Hairapetian gen. et sp. nov., Lutites plicatus Korn & Hairapetian gen. et sp. nov., Abichites ovalis Korn & Hairapetian sp. nov., Abichites infirmus Korn & Hairapetian sp. nov. and Stoyanowites parallelus Korn & Hairapetian sp. nov. The material described here is, together with the material from NW Iran, the most diverse assemblage known from the interval before the end-Permian mass extinction.
Signal transduction via phosphorylated CheY towards the flagellum and the archaellum involves a conserved mechanism of CheY phosphorylation and subsequent conformational changes within CheY. This mechanism is conserved among bacteria and archaea, despite substantial differences in the composition and architecture of archaellum and flagellum, respectively. Phosphorylated CheY has higher affinity towards the bacterial C-ring and its binding leads to conformational changes in the flagellar motor and subsequent rotational switching of the flagellum. In archaea, the adaptor protein CheF resides at the cytoplasmic face of the archaeal C-ring formed by the proteins ArlCDE and interacts with phosphorylated CheY. While the mechanism of CheY binding to the C-ring is well-studied in bacteria, the role of CheF in archaea remains enigmatic and mechanistic insights are absent. Here, we have determined the atomic structures of CheF alone and in complex with activated CheY by X-ray crystallography. CheF forms an elongated dimer with a twisted architecture. We show that CheY binds to the C-terminal tail domain of CheF leading to slight conformational changes within CheF. Our structural, biochemical and genetic analyses reveal the mechanistic basis for CheY binding to CheF and allow us to propose a model for rotational switching of the archaellum.
The Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO) here presents its updated recommendations for the treatment of documented fungal infections. Invasive fungal infections are a main cause of morbidity and mortality in cancer patients undergoing intensive chemotherapy regimens. In recent years, new antifungal agents have been licensed, and agents already approved have been studied in new indications. The choice of the most appropriate antifungal treatment depends on the fungal species suspected or identified, the patient’s risk factors (e.g., length and depth of neutropenia), and the expected side effects. This guideline reviews the clinical studies that served as a basis for the following recommendations. All recommendations including the levels of evidence are summarized in tables to give the reader rapid access to the information.
Two-particle correlation functions of negative hadrons over wide phase space, and transverse mass spectra of negative hadrons and deuterons near mid-rapidity have been measured in central Pb+Pb collisions at 158 GeV per nucleon by the NA49 experiment at the CERN SPS. A novel Coulomb correction procedure for the negative two-particle correlations is employed making use of the measured oppositely charged particle correlation. Within an expanding source scenario these results are used to extract the dynamic characteristics of the hadronic source, resolving the ambiguities between the temperature and transverse expansion velocity of the source, that are unavoidable when single and two particle spectra are analysed separately. The source shape, the total duration of the source expansion, the duration of particle emission, the freeze-out temperature and the longitudinal and transverse expansion velocities are deduced.
We report measurements of Xi and Xi-bar hyperon absolute yields as a function of rapidity in 158 GeV/c Pb+Pb collisions. At midrapidity, dN/dy = 2.29 +/- 0.12 for Xi, and 0.52 +/- 0.05 for Xi-bar, leading to the ratio of Xi-bar/Xi = 0.23 +/- 0.03. Inverse slope parameters fitted to the measured transverse mass spectra are of the order of 300 MeV near mid-rapidity. The estimated total yield of Xi particles in Pb+Pb central interactions amounts to 7.4 +/- 1.0 per collision. Comparison to Xi production in properly scaled p+p reactions at the same energy reveals a dramatic enhancement (about one order of magnitude) of Xi production in Pb+Pb central collisions over elementary hadron interactions.
The directed and elliptic flow of protons and charged pions has been observed from the semi-central collisions of a 158 GeV/nucleon Pb beam with a Pb target. The rapidity and transverse momentum dependence of the flow has been measured. The directed flow of the pions is opposite to that of the protons but both exhibit negative flow at low pt. The elliptic flow of both is fairly independent of rapidity but rises with pt. PACS numbers: 25.75.-q, 25.75.Ld
Using the NA49 main TPC, the central production of hyperons has been measured in CERN SPS Pb - Pb collisions at 158 GeV c-1. The preliminary ratio, studied at 2.0 < y < 2.6 and 1 < pT < 3 GeV c-1, equals ~ (13 ± 4)% (systematic error only). It is compatible, within errors, with the previously obtained ratios for central S + S [1], S + W [2], and S + Au [3] collisions. The fit to the transverse momentum distribution resulted in an inverse slope parameter T of 297 MeV. At this level of statistics we do not see any noticeable enhancement of hyperon production with the increased volume (and, possibly, degree of equilibration) of the system from S + S to Pb + Pb. This result is unexpected and counterintuitive, and should be further investigated. If confirmed, it will have a significant impact on our understanding of mechanisms leading to the enhanced strangeness production in heavy-ion collisions.
