Dadurch, dass es gelang, nach und nach die optischen Fehler zu korrigieren, verbesserte sich die Aufl{\"o}sung bis zum Ende des Jahrhunderts um den Faktor 10 von 3 μm auf 0,3 μm. Um 1820 begann Christian Gottfried Ehrenberg mit mikroskopischen Untersuchungen. Er nutzte zun{\"a}chst ein einfaches N{\"u}rnberger Mikroskop. 1832 erwarb er ein Mikroskop aus der Berliner Werkstatt von Pistor \& Schiek, das er dann zeitlebens nutzte. Ein Vergleich der Leistungsf{\"a}higkeit seines Instruments mit der f{\"u}r seine Untersuchungen notwendigen Aufl{\"o}sung zeigt, dass es f{\"u}r seine Untersuchungen vollkommen gen{\"u}gte. F{\"u}r seine Untersuchungsobjekte entwickelte er Pr{\"a}parationstechniken und Aufbewahrungsmethoden f{\"u}r die Dauerpr{\"a}parate. Da er auch die mikroskopischen Abbildungen bis hin zu den Vorlagen f{\"u}r die Kupfertafeln selbst anfertigte, behielt er den gesamten Prozess von der Pr{\"a}paration bis zum Druck der Ergebnisse stets in der Hand.}, language = {de} } @article{Boehme2021, author = {B{\"o}hme, Katrin}, title = {Das große Ganze.

Here, we investigate the relationship between EASM and EAWM as well as the mechanisms driving their variability during the last 10,000 years by stacking marine and terrestrial (non-speleothem) proxy records from the East Asian realm. This provides a regional and proxy independent signal for both monsoonal systems. The respective signal was subsequently analysed using a linear regression model. We find that the phase relationship between EASM and EAWM is not time-constant and significantly depends on orbital configuration changes. In addition, changes in the Atlantic Meridional Overturning circulation, Arctic sea-ice coverage, El Ni{\~n}o-Southern Oscillation and Sun Spot numbers contributed to millennial scale changes in the EASM and EAWM during the Holocene. We also argue that the bulk signal of monsoonal activity captured by the stacked non-speleothem proxy records supports the previously argued bias of speleothem climatic archives to moisture source changes and/or seasonality.}, language = {en} } @article{SchubarthSpeck2021, author = {Schubarth, Wilfried and Speck, Karsten}, title = {Ergebnisse zur Einsch{\"a}tzung des Referendariatsaus Sicht aller Akteure}, publisher = {Waxmann}, address = {M{\"u}nster}, isbn = {978-3-8309-4332-7}, pages = {254}, year = {2021}, language = {de} } @article{FranzkedelaFuente2021, author = {Franzke, Jochen and de la Fuente, Jos{\´e} M.
