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

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…

This thesis consists of three papers that are centered around the common theme of Hausdorff uo-Lebesgue topologies and convergence structures on vector lattices and on vector lattices and vector lattice algebras of order bounded operators.

Twee hoogleraren die op dezelfde dag hun oratie uitspreken, dat is een zeldzaamheid aan de Universiteit Leiden. Berna Güroğlu en Ellen de Bruijn zijn gespecialiseerd in aanverwante vakgebieden: beiden onderzoeken de invloed van sociale context op hersenprocessen. Güroğlu doet dat bij adolescenten, De…

What is the environmental impact of different waste collection systems across Europe? How can the collection be improved when considering collection, sorting, and treatment, as well as use options for secondary materials?

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

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-…

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

How do nanoparticles bioaccumulate and biodistribute in organisms?

Promotor: M.A.G.J. Orrit

We present an extensive study of methods for exactly solving stochastic constraint (optimisation) problems (SCPs) in network analysis. These problems are prevalent in science, governance and industry.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

We have studied the impact of particle shape anisotropy, multivalent interactions and flexibility on systems of micron-sized colloidal particles.

Humans perceive the real world through their sensory organs: vision, taste, hearing, smell, and touch. In terms of information, we consider these different modesalso referred to as different channels of information or modals.

Glucocorticoids are potent anti-inflammatory drugs widely used clinically to treat various inflammatory and immune conditions. However, two main clinical problems limit their use. GCs trigger severe side effects and they induce acquired glucocorticoid resistance, especially during chronic systemic treatment…

Dit artikel onderzoekt de oorzaken en onderzoekt hoe verschillende publieke percepties van de rechtsstaat bijdragen aan deze trend.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

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

Glycoside hydrolases (glycosidases/GHs) are widely abundant enzymes in all kingdoms of life and are important biocatalysts that catalyze the hydrolysis of glycosidic linkages in oligo/polysaccharides, glycoproteins and glycolipids with tremendous efficiency

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

Schistosomiasis is an acute and chronic disease caused by blood dwelling parasitic trematodes of the genus Schistosoma, and it is classified as the second most socioeconomically devastating parasitic disease, second only to malaria.

Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

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.

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.
