In Afrika wonen 1,5 miljard mensen. Over 30 jaar zijn dat er 2,5 miljard. De impact van het continent op de wereldeconomie, maar bijvoorbeeld ook op het milieu, zal daardoor enorm toenemen. Onderzoekers van het Afrika-Studiecentrum Leiden (ASCL) zijn zich er al decennia van bewust dat Afrika een cruciale…

Duurzaamheid is een van de centrale aandachtspunten van de Universiteit Leiden en speelt een steeds grotere rol binnen het onderwijs en onderzoek van de Faculteit der Rechtsgeleerdheid. Binnen deze context levert de afdeling Sociaal Recht een belangrijke bijdrage aan het debat en onderzoek rondom Business…

It researches (the possibilities for) the development of a set of principles and best practices for insolvency office holders by comparing multilateral treaties and soft law recommendations and national legislation within Europe.

Afrika heeft een bevolking van 1,5 miljard mensen. In 2050 zal dit aantal naar verwachting stijgen tot 2,5 miljard. De impact van het continent op de wereldeconomie en samenlevingen, maar ook op het milieu, zal daardoor enorm toenemen.

Op de Oude Sterrewacht bieden we een aantal manieren voor scholen om op bezoek te komen. Naast de rondleidingen die wij organiseren zijn er speciaal voor scholen ook workshops te doen.

Tijdens het najaarssemester (september-december) biedt het NIMAR een Engelstalige minor die zich richt op de studie van Marokko vanuit sociaalwetenschappelijk en geesteswetenschappelijk perspectief. Het semester onderwijst etnografische onderzoeksvaardigheden in een Marokkaanse omgeving.

In a typical glycosylation reaction, a donor is activated to form a (variety of) electrophilic species which can react with a nucleophilic acceptor, following a reaction mechanism having both SN1 and SN2 character.

Op 1 april 2020 verdedigde Marc Broekema zijn proefschrift 'Cognitive Bias in the Judgment of Business Valuations and Valuators'. Het promotieonderzoek is begeleid door promotor prof. dr. J.I. van der Rest.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

Obesity may alter how a person absorbs, distributes, metabolizes or excretes medication. This thesis describes how obesity affects drug levels in the blood for antimicrobial agents, such as ciprofloxacin and fluconazole.

Glycosidases (GHs) are enzymes responsible for the degradation of carbohydrates and play many roles in human health and pathophysiology. Often, abnormal levels of glycosidase activity are markedly linked to human pathologies.

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…

Phosphorylation affects all four major biomolecules – proteins, lipids, carbohydrates and nucleic acids – and plays a pivotal role in the most fundamental cellular functions.

Taking as a point of departure the Italian American community in Boston and its process of collective remembrance surrounding Saint Anthony’s Feast, we addressing the limits and potential of montage.

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

Trigonostemon Blume is a plant genus in the family Euphorbiaceae comprising 59 species.

Taxonomy as a science has accumulated data and knowledge for more than 250 years.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Het doel van dit project is het monitoren van levensdelicten in de Dutch Caribbean.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

At the moment, over 350.000 chemicals are registered worldwide for production and use. Their application, however, may harm human health and the environment.

In this thesis we investigate cosmology and the large scale structure of the Universe using cosmological simulations.

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

This thesis describes the design, characterization and application of dextran based crosslinked network.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

Industrial manufacturing processes, such as the production of steel or the stamping of car body parts, are complex semi-batch processes with many process steps, machine parameters and quality indicators.

The endocannabinoid receptors CB1R and CB2R are involved in a plethora of processes, and consequently are involved in many pathological conditions. Their wide distribution makes the CBRs both an interesting therapeutic target and hard to study.

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

Galaxy intrinsic alignments induce a major astrophysical contamination to weak gravitational lensing measurements and need to be modelled and mitigated when extracting cosmological information from such measurements.

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

The main subject of this thesis is the design and synthesis of paramagnetic molecules for protein studies with NMR and EPR spectroscopy.

This thesis introduces a relational interaction model and a practical tool for describing, visualising and generating interactive dialogues.
