In this thesis, we present new laboratory data of interstellar dust analogues.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

Religion and ethnicity are inextricably linked in discourse within and about Central Asia. One common narrative suggests that as a result of differences between historically sedentary and nomadic populations, ethnic Tajiks and Uzbeks are naturally more religious and more likely to radicalise than their…

The research provides insight into disease behavior in both rural and semi-urban areas in Serengeti in Tanzania.

Op 10 november 2021 verdedigde Carmel van Niekerk-Jacobs het proefschrift 'Realising the right to reproduce with assistance in South Africa'. Het promotieonderzoek is begeleid door prof.dr. J.J. Sloth-Nielsen en prof.dr. T. Liefaard.

Participants in this course will learn to support student teachers and new colleagues in their professional development as teachers, with particular emphasis on the context of bilingual or international education, as in the ICLON World Teachers Programme (WTP).

The aim of this project was to estimate emissions from lead products-in-use for the past, the present and the future and assess the development of toxicological risks associated with these products.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

Where does the urge to collect come from? What are the explicit or underlying reasons for gathering large amount of objects?

In de ontwikkeling van de Humanities Campus worden, zowel bij de gebouwen als bij het omringende gebied, zoveel mogelijk 'groene keuzes' gemaakt. De verduurzaming van de campus krijgt vorm aan de hand van beoordelingsmethode BREEAM-NL.

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

This thesis aimed to investigate core cross-linked polymeric micelles (CCPMs) and expand their potential for the delivery of hydrophobic drugs and co-factors.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Artificial intelligence algorithms govern in subtle, yet fundamental ways, the way we live and are transforming our societies. The promise of efficient, low‐cost or ‘neutral’ solutions harnessing the potential of big data has led public bodies to adopt algorithmic systems in the provision of public…

This thesis discusses several questions regarding the double ramification cycle as a Chow class on the moduli space of stable n-pointed genus g curves using tools from so-called logarithmic geometry.

The research described in this thesis focused on the use of bioorthogonal antigens to investigate immunological processes in antigen presenting cells. Bioorthogonal antigens are antigenic proteins produced through recombinant expression in a methionine auxotrophic E. coli strain.

In this thesis, several aspects of software debugging from automated crash reproduction to bug report analysis and use of contracts have been studied.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

The haplolepideous mosses (Dicranidae) comprise about 4000 species distributed over a wide range of habitats, with great gametophytic and sporophytic morphological variation. Their monophyly is well supported by the results of several molecular phylogenetic studies, which shed light on their relationships…
