De jongeren van nu groeien op met sociale media. Mogelijk heeft dat invloed op de ontwikkeling van herssengebieden die betrokken zijn bij sociale interactie. Crone en Konijn laten in dit overzichtsartikel in Nature Communications zien hoe neurowetenschappelijke kennis kan bijdragen aan een beter begrip…

Bij onderwijsvernieuwing wordt vaak nascholing ingezet, maar die is niet altijd effectief. In haar proefschrift onderzocht Nienke Wieringa (ICLON) welke ondersteuning docenten nodig hebben bij onderwijsvernieuwing.

In dit interdisciplinaire project worden data science technieken toegepast om de interactie tussen de Universiteit en stad Leiden (Town&Gown) kwalitatief en kwantitatief zichtbaar te maken vanaf 1575. Een van de mogelijke invalshoeken voor vervolgonderzoek is diversiteit, met name vanuit de internationale…

This thesis has three main parts. The first part gives an algorithm to compute Hilbert modular polynomials for ordinary abelian varieties with maximal real multiplication. Hilbert modular polynomials of a given level b give a way of finding all of the abelian varieties that are b-isogeneous to any given…

The project Multimedia Research and Documentation of African Oral Genres: Connecting Diasporas and Local Audiences (Director: D.Merolla) focuses on multimedia as technology that allows scholars to share documentation and scientific knowledge with the cultural owners of the collected oral genres.

In summary, the collective results described in this thesis show that nanoparticulate vaccines can be delivered intradermally by coated and hollow microneedles and evoke antigen-specific immune responses.

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

Bacteria are highly complex and diverse organisms that have adapted to survive in ecological niches ranging from the most extreme to the most heterogeneous environments.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

Op 11 november 2021 verdedigde Mariana Gkliati het proefschrift 'Systemic Accountability of the European Border and Coast Guard'. Het promotieonderzoek is begeleid door promotoren prof.dr. P. Rodrigues en prof.dr. L. Besselink (UvA).

This project uses archaeological, literary and epigraphic evidence to investigate urban development in Roman-period North Africa, compiling this in a GIS-linked database in order to analyse the development of urban settlement spatially over time.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

Due to their central physiological roles in living organisms, retaining beta-glycosidases have been the subject of tremendous research efforts to examine their structure/function relation using numerous biophysical and biochemical approaches.

Engelsen hebben een groot normbesef als het gaat om taal: in formele situaties hoor je beschaafd Engels te spreken. Toch zijn de meesten tijdens het dagelijks taalgebruik wel een stukje milder in hun oordeelen bepaalde zinsconstructies te vermijden. Dat blijkt uit een onderzoek van taalkundige Carmen…
