The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

The mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

Adults are more likely to reoffend after a short prison sentence than comparable adults with a non-custodial sentence, Leiden University research shows. This is true for the likelihood and extent of repeat crime.

This research paper seeks to examine the nature of the nexus between right-wing extremism and the military by surveying five potential consequences (i.e., problem areas) arising from the presence of right-wing extremists within the armed forces of twelve Western countries.
