Befindet sich die Religion auf dem Rückzug gegenüber der vordringenden Wissenschaft? Welche Theorien gibt es zur Verhältnisbestimmung von Wissenschaft und Religion und was ist ihre wirkliche Differenz? Martin Buber geht diesen Fragen in einem bis vor kurzem noch unveröffentlichten Zürcher Referat nach. Der Essay kommentiert die Bemühungen Bubers um eine Klärung dieser Verhältnisbestimmung und stellt sie in den Kontext der heute international geführten Diskussion über Wissenschaft und Religion.

Heterodyne receivers at millimeter and submillimeter wavelength are widely used for radiometric spectral line observations for atmospheric remote sensing or radio astronomy. The quantitative analysis of such observations requires an accurate knowledge of the mixers's sideband ratio. In addition, its potential sensitivity to spurious harmonics needs to be well understood. In this paper, we discuss a measurement technique for these receiver characteristics, which is based on a scanning Martin Puplett Interferometer used in conjunction with a wide band digital autocorrelation spectrometer for the analysis of the intermediate frequency band. We present measurement results of different double sideband and sideband separating mixers, which were developed for the proposed 340GHz multi-beam limb sounder STEAMR.

OBJECTIVES Loeys-Dietz syndrome (LDS) is characterized by acute aortic dissection (AAD) at aortic diameters below thresholds for intervention in patients with Marfan syndrome (MFS). The aim was to evaluate the outcome of LDS patients primarily treated as having MFS. METHODS We analysed 68 consecutive patients who underwent surgery between 1995 and 2007 under the assumption of having MFS before retrospectively being screened for LDS when genetic testing became available. These patients were followed up until 2013, and underwent a total of 115 aortic surgeries. RESULTS Genetic testing was performed in 76% of the patients. Sixty per cent of these patients were positive for FBN1 mutations associated with MFS, 20% had no FBN1 mutation and 17% harboured TGFBR1/2 mutations associated with LDS. Mean follow-up was 12.7 ± 7 years. All-cause 30-day, 6-month and 1-year mortality rates were 2.9, 4.4 and 7.3%, respectively. Interestingly, initial presentation with AAD did not differ between LDS and MFS (33 vs 37%, P = 0.48) nor did long-term mortality compared with MFS patients (11 vs 16%, P = 1.0) or within MFS subgroups (FBN1 positive 13%, P = 1.0; FBN1 negative 10%, P = 1.0; not tested 25%, P = 0.62). There was no difference in the need for secondary total arch replacement between LDS and MFS patients (11 vs 14%, P = 1.0), nor within MFS subgroups (FBN1 positive 16%, P = 1.0; FBN1 negative 10%, P = 1.0; not tested 13%, P = 1.0). Total aortic replacement became necessary in 22% of LDS compared with 12% of MFS patients (P = 0.6) and did not differ significantly between MFS subgroups. CONCLUSIONS Although early surgical intervention in LDS is warranted to avoid AAD, the current data suggest that once the diseased segment is repaired, there seems to be no additional burden in terms of mortality or reoperation rate compared with that in MFS patients, with or without confirmed FBN1 mutation.

Aktuelle Inszenierungen denken den ästhetischen Rahmen, in dem sie sich ereignen, oftmals dezidiert mit. Sie machen ihn zum Thema, stellen ihn zur Disposition oder üben praxisimmanent Kritik am Kunstsystem, in dem sie operieren und von dem sie abhängig sind. Exemplarisch für diese Tendenz fokussiert dieser Aufsatz die 2011 im Rahmen von Freischwimmer entstandene Produktion CMMN SNS PRJCT von Laura Kalauz und Martin Schick. Es wird aufgezeigt, wie Kalauz und Schick einerseits mit den Mitteln des Theaters gesellschaftspolitische Themen in spielerischen Interaktionen gemeinsam mit dem Publikum aushandeln und andererseits das Aufführungsdispositiv sowie Rolle von Rezipienten und Produzenten stets aufs Neue zur Disposition stellen.
