Petrological analyses and Lu-Hf geochronology of subducted continental and oceanic crust from different locations in the upper and lower plate of the Caledonian Orogen
(2020-03-09)
In this thesis I conducted Lu-Hf analyses on samples from locations all over the Caledonian Orogen. I combined these ages with petrological analyses in order to help to unravel some of the open questions concerning the ...
Spaceborne SAR Remote Sensing for Monitoring of Vegetation Dynamics in Arid and Semi-arid Environment
(2020-04-22)
Drylands are under constant threat from multiple stresses and challenges, which occur as a result of a complex interaction of natural processes, and human-induced processes caused by unsustainable land use practices, leading ...
Impact of UGT1A polymorphisms on inflammation and fibrogenesis in a humanized transgenic mouse model
(2020-07-07)
Fibrogenesis represents a highly dynamic scarring response of the liver resulting from different causes of hepatic injury. A key process capable of activating a broad array of profibrogenic pathways is oxidative stress. ...

(2021-10-26)
Schülerinnen und Schüler werden in ihrer Alltagswelt seit dem letzten Jahrzehnt immer früher mit Satellitenbildern konfrontiert. Durch den Wetterbericht und die Nachrichtensendung im Fernsehen oder durch virtuelle Globen ...
Verbesserung der Befundinterpretation bei forensisch-toxikologischen Fragestellungen am Beispiel von Prothipendyl, Cannabinoiden und neuen psychoaktiven Substanzen: Bedeutung von Metaboliten und Referenzdaten
(2020-01-06)
Für eine umfassende forensisch-toxikologische Interpretation von Substanznachweisen in biologischen Matrizes bedarf es einer fundierten Datenlage. Neben pharmakologischen bzw. toxikologischen Eigenschaften der Substanzen ...
Climate field reconstructions from pollen and macrofossil syntheses using Bayesian hierarchical models
(2020-01-09)
Studying past climate states is important to understand climate changes and climate variability on centennial to orbital timescales, to analyze the reaction of the Earth system to large-scale changes in external forcings, ...
Mechanisms of epileptogenesis in animal models of developmental brain lesions
(2021-11-05)
Developmental brain lesions, including glioneuronal tumors (GNT) and malformations of cortical development (MCD), are among the most common causes for pharmaco-resistant epilepsy. Despite substantial differences, their ...
