    Beschreibung: Das Verhältnis von Religion und Politik ist in den vergangenen Jahren verstärkt in den Fokus der Forschung gerückt. Die Autoren dieses Bandes widmen sich diesem Verhältnis unter einer besonderen Zuspitzung. Ihre Beiträge analysieren, inwiefern es zum Selbstverständnis von Religionen gehört, einen Beitrag zur Gestaltung der gesellschaftlichen und politischen Wirklichkeit leisten zu sollen. Mit dieser Problematik verknüpft ist eine zentrale Frage: Wie erklärt und wie äußert sich der Anspruch von Religionen, eine »politische Aufgabe« zu besitzen? Im Fokus stehen die drei großen monotheistischen Religionen Judentum, Christentum und Islam, wobei für das Christentum zusätzlich die konfessionellen Differenzen in den Blick kommen, die zu ganz unterschiedlichen Einschätzungen der politischen Aufgabe des Christentums geführt haben.Für alle drei monotheistischen Religionen nehmen die Beiträger jeweils eine Doppelperspektive ein: historische Beispiele erhellen die jeweiligen Bedingungen und Kontexte für religiös motivierte Teilhabe an politischer Gestaltung und Verantwortung; Systematische Entfaltungen versuchen eine Einbettung dieser Beispiele in die spezifischen Denkhorizonte der jeweiligen Religionen. Das so erhobene politische Selbstverständnis der Religionen wird schließlich mit der Fremdwahrnehmung dieses Selbstverständnisses aus nichtreligiöser Perspektive kontrastiert.

    Notizen: A Rutherford scattering diagnostic has been applied at the TEXTOR tokamak to obtain spatially and temporally resolved information on the temperature of the bulk ions in the plasma. In the experimental setup, a helium atomic beam (30-keV, 12-mA equivalent current) passes vertically through the plasma core. A small part of the injected atoms is scattered elastically by the thermally moving plasma ions. The ion temperature in the scattering volume can be determined from the broadening of the energy spectrum of the scattered particles. Energy analysis of the scattered atoms is performed by a mass-selective time-of-flight analyzer detecting the particles at an observation angle which is selectable between 3° and 8°. Coincidence techniques have been successfully applied in this detector for rejection of background events triggered by detections of neutrons and gamma radiation. Ion temperature profiles were measured on a shot-to-shot basis by shifting the cross section of the diagnostic beam and the observational volume of the analyzer through the plasma. The ion temperatures measured in ohmic deuterium plasmas were found to be in reasonable agreement with those obtained from passive neutral particle analysis. Up to now, ion temperatures have been measured throughout the complete discharge with an accuracy of 8% and a time and space resolution of 100 ms and 0.10 m at a scattering angle of 7°. Deuteron density profiles could be deduced from the scattering yield measured at different radial positions in the plasma. The ratio of the isotopes, hydrogen and deuterium, was determined from their separate contributions to the spectrum of helium particles scattered on hydrogen and deuterium. Although theoretical predictions showed that the majority of the probing helium atoms loses one of its electrons during the elastic scattering process on multiply charged carbon and oxygen ions, contributions from impurities to the observed experimental spectrum are shown to appear dominant for impure plasmas.

    Notizen: The Rutherford scattering diagnostic at TEXTOR is used to perform temporal and spatial resolved measurements of the ion temperature. Function parametrization techniques are used for fast analysis of the complex spectra, which also contain information about the presence of impurities in the scattering volume. The (perpendicular) central ion temperature has been determined for a series of discharges, where neutral beam coinjection (hydrogen) was applied to plasmas of different densities. A temperature of 2.8 keV was found for a line-averaged electron density of 1.5×1019 m−3, decreasing monotonically for higher densities to 0.8 keV at 6.0×1019 m−3. When deuterium was used as heating beam species, scattering on a high-Z impurity, probably tungsten from the filaments of the NBI sources, gave a dominant contribution to the spectra.

    Notizen: Abstract The Saccharomyces cerevisiae nuclear gene MRP-L6 was cloned by complementation of the respiratory-deficient mutant pet-ts 2523 with a library of wildtype yeast genomic DNA. The isolated gene was part of a 3.8-kb sequenced DNA fragment containing, in addition to MRP-L6, two unassigned reading frames, ORF1 and ORF2. MRP-L6 codes for a basic protein of 205 amino acids and a molecular mass of 22.8 kDa. The protein exhibits significant sequence similarity to the ribosomal protein L6 of bacteria and chloroplasts. Unlike the corresponding bacterial proteins, however, the MRP-L6 protein (MRP-L6p) contains at its N-terminus a 16 amino-acid leader sequence exhibiting the known characteristics of mitochondrial import signals. Disruption of MRP-L6 leads to the phenotype of a mitochondrial translation-defective, rho-negative yeast mutant. The results are consistent with MRP-L6p representing an essential component of yeast mitochondrial ribosomes. Expression of MRP-L6 was examined, under conditions of glucose repression and derepression, in wild-type cells and in a series of catabolite repression-defective yeast mutants. In most cases, a distinct though small influence of the carbon source on the expression of an MRP-L6/lacZ reporter construct was observed.

    Notizen: Abstract The ICL1 gene encoding the isocitrate lyase from Saccharomyces cerevisiae was cloned and sequenced. A reading frame of 557 amino acids showing significant similarity to isocitrate lyases from seven other species could be identified. Construction of icl1 null mutants led to growth defects on C2 carbon sources while utilization of sugars or C3 substrates remained unaffected. Using an ICL1-lacZ fusion integrated at the ICL1 locus, a more than 200-fold induction of β-galactosidase activity was observed after growth on ethanol when compared with glucose-repressed conditions. A preliminary analysis of the ICL1 upstream region identified a 364-bp fragment necessary and sufficient for this regulatory phenotype. Sequence motifs also present in the upstream regions of co-regulated genes were found within this region.

    Thema: Biologie
    Notizen: Summary Fructose-1,6-bisphosphatase is a key enzyme in gluconeogenesis and the FBP1 gene is not transcribed during growth with glucose. Genetic analysis indicated a positive regulation of FBP1 expression after exhaustion of glucose. By linker-deletion analysis, two upstream activation sites (UAS1 and UAS2) were localized and the respective UAS-binding factors (DAP I and DAP II for derepression activating protein) were identified by gel retardation. UAS1 and UAS2 span about 30 bp each, and are separated by approximately 30 bp. Both UAS sites act synergistically. Although UAS1 showed some similarities to the DNA-binding consensus for the general yeast activator Rap1, competition experiments and DEAE-chromatography proved that DAP I and Rap1 correspond to different proteins. Gel retardation by DAP I depended on carbon sources and did not occur in cells growing logarithmically with glucose, whereas a strong retardation signal was obtained with ethanol-grown cells. The present results suggest that DAP I and DAP II are the final regulatory elements for glucose derepression.
