Satellite remote sensing provides a powerful instrument for mapping and monitoring traces of historical settlements and infrastructure, not only in distant areas and crisis regions. It helps archaeologists to embed their findings from field surveys into the broader context of the landscape. With the start of the TanDEM-X mission, spatially explicit 3D-information is available to researchers at an unprecedented resolution worldwide. We examined different experimental TanDEM-X digital elevation models (DEM) that were processed from two different imaging modes (Stripmap/High Resolution Spotlight) using the operational alternating bistatic acquisition mode. The quality and accuracy of the experimental DEM products was compared to other available DEM products and a high precision archaeological field survey. The results indicate the potential of TanDEM-X Stripmap (SM) data for mapping surface elements at regional scale. For the alluvial plain of Cilicia, a suspected palaeochannel could be reconstructed. At the local scale, DEM products from TanDEM-X High Resolution Spotlight (HS) mode were processed at 2 m spatial resolution using a merge of two monostatic/bistatic interferograms. The absolute and relative vertical accuracy of the outcome meet the specification of high resolution elevation data (HRE) standards from the National System for Geospatial Intelligence (NSG) at the HRE20 level.

Von der Hauptstadt Rom aus gesehen liegt der vicus Tasgetium (Eschenz TG) am Rande des römischen Imperiums. Unter günstigen Voraussetzungen konnten sich hier jedoch über die Jahrtausende Befunde und Funde aus Holz aussergewöhnlich gut erhalten, eine Seltenheit im römischen Reich! Der Vortrag stellt einige dieser Befunde vor und vermittelt Einblicke in die römische Holzbautechnik.

Textiles fund in Bern-Engehalbinsel are dated to the late La Tène period and show similar qualities and pattern. Their function was garments, probably a tunic hold by pins.

Various assays have been used as an aid to diagnose failure of passive transfer (FPT) of immunoglobulins in neonatal foals, but often lack sensitivity as screening tests, or are time consuming to perform and impractical as confirmatory tests. The aim of the present study was to evaluate whether measurement of serum total globulins (TG; i.e. total protein minus albumin) can be used to estimate the electrophoretic gamma globulin (EGG) fraction in hospitalised neonatal foals with suspected FPT. Sample data from 56 foals were evaluated retrospectively. The coefficient of rank correlation was 0.84. The area under the curve of ROC analysis was 0.887, 0.922 and 0.930 for EGG concentrations <2 g/L, < 4 g/L and <8 g/L, respectively. Cut-offs for TG achieved ≥90% sensitivity for detecting EGG <2 g/L, < 4 g/L and <8 g/L, with negative predictive values of >97% and >94%, using prevalence of 15% and 30%, respectively. These results suggest that measurement of TG can be used as a guide to predicting EGG, provided that appropriate cut-off values are selected, and this technique could be a useful initial screening test for FPT in foals.

Was das Heilige ist und wie man darüber sprechen kann, ist eine offene Frage in der religionswissenschaftlichen und theologischen Forschung. Jenseits der klassischen Entwürfe von Durkheim, Otto oder Eliade kann Heiliges heute nur in multiperspektivischer Betrachtung angemessen untersucht werden. Die Beiträge zu diesem Band analysieren Diskurse über Heiliges in spätantiken Religionskulturen: griechisch-römische Religion, Judentum und Christentum. Terminologien, Handlungen und Reflexionen in Bezug auf Heiliges werden in ihrem jeweiligen religiösen Bezugssystem thematisiert, aber darüber hinaus auch miteinander ins Gespräch gebracht. Hierfür dienen Kategorien wie Zeit, Ort, Individuum und Gruppe der Zuordnung der Befunde. Besonderes Augenmerk liegt zudem auf quellensprachlichen und forschungsinternen Begrifflichkeiten von Heiligem sowie auf der geschichtlichen Dynamik von Heiligkeitsvorstellungen. Dieses interdisziplinäre Vorgehen macht Diskontinuitäten und Kontinuitäten des Diskurses über „das Heilige“ in der Vielfalt seiner Erscheinungsformen präziser als bisher identifizierbar.
