Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

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

Herkennen huisartsen kinderen die (een verhoogd risico voor) angststoornissen hebben en is er een patroon dat kan helpen om kinderen met en zonder angststoornissen te onderscheiden in de huisartsenpraktijk?

Dit boek, samengesteld door voormalig BVD-historicus Dick Engelen en historicus Constant Hijzen, geeft een overzicht van lokaties in Nederland die in de twintigste eeuw iets te maken hebben gehad met spionage en geheime diensten uit binnen- en buitenland.

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

The research described in this thesis shows that hypercholesterolemia, a well-established risk factor for atherosclerosis, can impact skin lipid pool and barrier function already at young age. In the field of atherosclerosis, we showed that the small peptide Lyp-1 can be used as a targeting molecule…

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

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

This thesis describes biochemical investigations of glucocerebrosidase (GBA), the lysosomal β- glucosidase that is deficient in Gaucher disease (GD).

Van zelfrijdende auto’s tot innovatieve medicijnontwikkeling, kunstmatige intelligentie (AI) gaat ons leven op uiteenlopende manieren fundamenteel veranderen. Onze computerwetenschappers bestuderen de technologie op een diep en fundamenteel niveau. Maar we zoeken ook naar medische toepassingen en antwoorden…

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

Making a dynamic substance stock model in order to conduct scenario analyses and make forecasts.

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.

Overall dispersion in LCA as result of inherent uncertainties, spread and unrepresentativeness.

Predictive maintenance (PdM) is a maintenance policy that uses the past, current, and prognosticated health condition of an asset to predict when timely maintenance should occur.

Migration imposes special pressures on the meaning, experience and organization of lifecycle rituals. These pressures are felt most strongly by Muslim migrants to Western Europe. In this innovative study, Nathal M. Dessing examines the effects of migration on the life cycle rituals of Moroccan, Turkish…

De Universiteit Leiden streeft naar impact van haar onderzoek en onderwijs op de samenleving. Veel van onze onderzoekers werken daarom samen met academische en maatschappelijke partners, overheidsinstellingen, non-gouvernementele organisaties en het bedrijfsleven.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

Songbirds as vocal learners learn their songs and song preference from social tutors⁠. Tutor choice for both song and preference learning are important to characterize for understanding individual learning performance and cultural transmission of song⁠.

Lysosomal acid glucosylceramidase (GBA1) is a lysosomal enzyme that degrades glucolipids with its main substrate being glucosylceramide (GlcCer). Defects in the GBA1 gene lead to glycosphingolipidosis Gaucher disease (GD), in which the hydrolysis of GlcCer is impaired and therefore, it accumulates in…

The way organisms develop from the initial single-cellular state to a complex final assembly like the human body, and how the final body is maintained throughout life, is one of the greatest mysteries and it’s understanding one of the biggest scientific challenges.
