Dreizler, Tom Kirchner & Cora S. Lüdde, published by Springer-Verlag GmbH Germany, part of Springer Nature in 2018. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com).

Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors. weiterlesen
