Mineralogy-based quantitative precipitation and temperature reconstructions from annually laminated lake sediments (Swiss Alps) since AD 1580

[1] We present quantitative autumn, summer and annual precipitation and summer temperature reconstructions from proglacial annually laminated Lake Silvaplana, eastern Swiss Alps back to AD 1580. We used X-ray diffraction peak intensity ratios of minerals in the sediment layers (quartz qz, plagioclase pl, amphibole am, mica mi) that are diagnostic for different source areas and hydro-meteorological transport processes in the catchment. XRD data were calibrated with meteorological data (AD 1800/1864–1950) and revealed significant correlations: mi/pl with SON precipitation (r = 0.56, p < 0.05) and MJJAS precipitation (r = 0.66, p < 0.01); qz/mi with MJJAS temperature (r = −0.72, p < 0.01)and qz/am with annual precipitation (r = −0.54, p < 0.05). Geological catchment settings and hydro-meteorological processes provide deterministic explanations for the correlations. Our summer temperature reconstruction reproduces the typical features of past climate variability known from independent data sets. The precipitation reconstructions show a LIA climate moister than today. Exceptionally wet periods in our reconstruction coincide with regional glacier advances.

Der erste Mord. Der Tod des Apsyrtos als Schlüsselmoment für moderne Interpretationen des Medea-Mythos: Jahnn, Pasolini, Wolf, Loher

Murderous Medea – following Euripides’ seminal tragedy countless authors and artists have depicted Medea as child-slaughtering outlaw and avenger. But the Medea myth is much more diverse and holds more depth than this. Medea’s path through her career as princess, magician, wife, mother and avengress opens with another abominable death: that of her brother Apsyrtos. This article focuses on how and why the death of Medea’s brother Apsyrtos has been examined and instrumentalised in modern adaptions of the myth by Hans Henny Jahnn, Pier Paolo Pasolini, Christa Wolf and Dea Loher. Whether guilty as charged but with sensible intentions to gain self-rule and show herself trustworthy or innocent of crime or murder but stricken with guilt and alienation, Medea’s involvement in her brother’s death seems to hold the key to modern interpretations of antiquity’s different strands of the Medea myth and its adaptability to modern concerns of subjectivity and emancipation.

Tibial Plateau angles with and without cranial cruciate ligament rupture: comparison between different dog populations and a wolf population.

The tibial plateau angles (TPA) of dogs with and without cranial cruciate ligament (CrCL) injuries were evaluated and further compared to the TPAs of dogs from a previous population and of wolves. Similar TPA measurements were found in all groups, suggesting that any possible changes in breeding practises, breed preferences, nutrition or other factors have not significantly influenced the TPA over time. Moreover, a difference was not found in the TPA between any group and the group affected with CrCL injury, suggesting that the TPA is not a clinically relevant predisposing factor in the development of canine CrCL rupture.
