At the end of 2021 an experiment with regard to the oldest boat in the world was published. For the full text we refer to ‘Jaap Beuker Academia edu’ (with English summary)
In 2022, a large collection of 16th century church coins from the Drents Museum and from a private collector was photographed by TriJaXa for publications (by V.T. van Vilsteren) and registration in the Museum.
From April 2021, TriJaXa participated in an archaeological investigation near Assen of a site from the last part of the ice age. Such sites are extremely rare in the north of the Netherlands. At the end of 2022, two publications will be published on this research.
Trijaxa facilitated the financial settlement of the book « Overpeinzingen op een vuilnisbelt”, the Liber Amicorum at the farewell to Dr. W.A.B. van der Sanden (ISBN 9789493194038). The book consists of 24 contributions by well-known Dutch authors.
