What are the critical elements in sonic materialization of fixed media electroacoustic music and how can these parameters be classified? How would interpretation be defined in performing fixed media music? What are the creative and new ways of presenting fixed media music by incorporating all the presentation…

Our in-house human skin equivalents contain all stratum corneum (SC) barrier lipid classes, but have a reduced level of free fatty acids (FAs), of which a part is mono-unsaturated. These differences lead to an altered SC lipid organization and thereby a reduced barrier function compared to human skin.…

African oral literatures, new media and technologies: challenges for research and documentation

Leiden Law School has a strong tradition of research in the field of fact-finding and evidence in criminal cases.

If you follow the western media, you are likely to think of ‘Africa’ as the continent of origin of desperate migrants, a continent of hunger and disease and a breeding ground for international terrorism. But if you want to see the bigger picture, you should look no further than the African Studies scholars…

Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

Linguistic research on a unique collection of Dutch letters allowed us to gain access to the every-day language of people from various walks of life. Private letters by men, women and even children have been elaborately explored in the Letters as Loot researchprogramme, initiated and directed by prof.…
