Totale Mondfinsterniss 1898 Dec. 27

Structure in the radio counterpart to the 2004 Dec 27 giant flare from SGR 1806 - 20

On Dec 27, 2004, the magnetar SGR 1806-20 underwent an enormous outburst resulting in the formation of an expanding, moving, and fading radio source. We report observations of this radio source with the Multi-Element Radio-Linked Interferometer Network (MERLIN) and the Very Long Baseline Array (VLBA). The observations confirm the elongation and expansion already reported based on observations a...

C1py00484k 1890..1898

End-functionalized polyethylene oxides containing cleavable acetal and clickable azide terminal groups (PEO-acetal-N3 and N3-acetal-PEO-acetal-N3) were obtained by the reaction between commercially available PEOs and 2-chloroethyl vinyl ether using pyridinium p-toluenesulfonate. This results in acetal-linkages which can be further functionalized by nucleophilic displacement with sodium azide. B...

Hilde Mangold-Pröscholdt (1898 – 1924)

In the history of medicine, few women were awarded an eponym. One can assume that this doesn’t have anything to do with their second X-chromosome or the weight of their brains. Most probably, it was the era that was not on their side. In the time period wherein most eponyms were given, women had almost no access to higher education. There are a few exceptions of course, such as Marie Curie or V...

Helen B. Taussig (1898-1986)

Together with Alfred Blalock, Helen Taussig rose to fame because of the Blalock-Taussig shunt. This is a surgical procedure in children who suffer from hypoxia because of a congenital cardiac malformation. Because of this affliction, they are blue. Less known is the fact that dr. Taussig also played a crucial role in the prohibition of thalidomide in the USA, the drug that had been responsible ...
