Door sterk gewijzigde maatschappelijke ontwikkelingen is voor de verhouding van staat en religie in Nederland de laatste decennia meer publieke belangstelling ontstaan dan ooit kon worden voorzien. Daarnaast is deze belangstelling langzamerhand een vraagstuk geworden die belangrijk is voor zowel de…

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).

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…

The applications of studying the early development of insects range from agriculture to material science.

Supramolecular polymers are class of materials that are formed by non-covalent interactions such as hydrogen bonding, π-π interactions, electrostatic interactions and the hydrophobic effect.

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

Cardiovascular disease is the leading cause of death worldwide.

This research focuses on the distribution of chemical elements in protoplanetary disks, the birthplaces of planets. These disks form around young stars and contain gas and dust, from which planets grow. Ice plays a crucial role in planet formation, aiding the clumping of dust particles and influencing…

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

A key step in the synthesis of oligosaccharides and glycoconjugates is the formation of the glycosidic bond.

Al twee eeuwen lang wordt er strijd geleverd over studiefinanciering. Hoe zouden geld en kansen verdeeld moeten worden? In hoeverre mag de staat zich daar mee bemoeien? Wie moet voor studiefinanciering betalen, en wie mag ontvangen? Deze vragen raken aan grote politieke en maatschappelijke verschillen…

Tot de Bataafse Revolutie van 1795 kwamen op het Binnenhof regenten in de Staten-Generaal samen namens zeven soevereine provincies om de Republiek te besturen. Twintig jaar later waren de Staten-Generaal (inmiddels verzamelnaam voor de Eerste en Tweede Kamer) enkel nog medewetgever naast koning Willem…

Within this thesis the central stage is taken by the discovery and investigation of transglycosylation of sterols. First, investigation focuses on the development of a method to accurately detect and quantify glucosylated metabolites in biological materials.

Op donderdag 13 oktober 2022 heeft de afdeling Staats- en bestuursrecht afscheid genomen van Elly van der Tang- van Loenen die jarenlang fungeerde als mastermentor aan de afdeling Staats- en bestuursrecht van de Universiteit Leiden. Na jaren met veel plezier deze functie te hebben uitgeoefend gaat Elly…

In this thesis, we used genetically engineered mouse models to identify genes and pathways that are involved in ILC formation and in the development of resistance to FGFR-targeted therapy.

Hydrogen peroxide (H2O2) is an important bulk chemical that is used in various industrial processes. More than 95% of the H2O2 used in industry is made via the anthraquinone process during which a large amount of energy is going to waste.

Op vrijdag 8 september vond de jaarlijkse kick-off van de master Staats- en bestuursrecht plaats. De nieuwe studenten werden in het Kijkhuis welkom geheten door Michiel Tjepkema. Vervolgens gaf Sebastiaan Renkema een presentatie over de activiteiten van de studievereniging Res Publica. De mastercoördinator…

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

This thesis is an experimental study of the UV irradiation of the interstellar ice analogues, relevant for the different stages of the star and planet formation sequence.

Indigenous Latin American artifacts have attracted the interest of Europeans since the earliest moment of contact between Europeans and the Indigenous peoples of the Americas. The ERC-funded BECACO project uses an innovative multidisciplinary framework to investigate the provenance of ethnographic and…

Op vrijdag 9 september jl. organiseerde de afdeling Staats- en Bestuursrecht, in samenwerking met studievereniging Res Publica, de traditionele Master Kick-off als aftrap van het nieuwe collegejaar.

In september 2012 verscheen onder redactie van T. Bosch en L. Wessels het boek 'Nationalisme, naties en staten. Europa vanaf circa 1800 tot heden'. Dit fraai uitgegeven werk (704 blz.) is een product van de samenwerking tussen de Open Universiteit en Uitgeverij Vantilt.

The thesis is about the study of shell evolution of the Hydrocenidae of the genus Georissa. This thesis started with a general overview on the evolutionary process of animals due to ecological changes.

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…
