Glycosidases are important enzymes in the turnover of polysaccharides and glycoconjugates, and are involved in a range of human pathologies including genetic disorders such as Gaucher and Pompe disease, but also in various cancers.

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

Het doel van dit proefschrift is om eerst te onderzoeken welke vormen van samenwerkend leren bij de verschillende conservatoria in de praktijk worden gebracht, om vervolgens te kijken naar hoe samenwerkend leren kan worden geïmplementeerd.

De focus van dit proefschrift is het leren en de samenwerking van docenten in het voortgezet onderwijs.

In dit proefschrift staat het leren van ervaren docenten in een context van samenwerking in interdisciplinaire teams centraal.

Het vertrouwen in de rechterlijke macht liep in de Tweede Wereldoorlog een flinke deuk op omdat veel rechtsinstanties gewoon doorwerkten onder de Duitse bezetting. Dat de opstelling ook een andere kon zijn, liet de Nijmeegse hoogleraar Corjo Jansen op 5 april zien tijdens een lezing bij de Hoge Raad…

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

Let A be a commutative algebraic group over a field K, and let G be a finitely generated subgroup of the K-rational points of A. The purpose of this thesis is to study the degrees of the Kummer extensions relative to A,K and G.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

“Temminck’s Order” is the scientific biography of Coenraad Jacob Temminck (1778–1850), a Dutch naturalist and the first director of ’s Rijks Museum van Natuurlijke Historie in Leiden.

Politicologiestudent Jacomijn Visser won in 2014 de J.Th.J. van den Berg-prijs voor de beste bachelorscriptie in het Leidse Instituut Politieke Wetenschap. Samen met haar begeleiders werkte zij haar bachelorscriptie om tot een artikel. Dit wordt in december 2015 gepubliceerd in het tijdschrift Bestu…

This thesis focusses on the temperature structure in protoplanetary disks. The relation between structures seen in the dust and gas-phase molecules is investigated.

Op 19 februari 2020 verdedigde Richard Jiang zijn proefschrift '‘Greening’ the WTO Ban on China’s Export Duties'. Het promotieonderzoek is begeleid door promotor prof.dr. M.C.E.J. Bronckers.

Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

Anthonya (Thony) Visser, Leids hoogleraar Duitse taal en literatuur, is gedurende zes maanden senior fellow aan het Freiburg Institute for Advanced Studies. ‘Ik heb nu tijd, dat is misschien wel het allerbelangrijkste.’

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

Het Nationaal Regieorgaan Onderwijs (NRO) kent namens het Ministerie van OCW de Comenius Teaching Fellow-beurs toe aan 38 docenten, waaronder Tarlach McGonagle, hoogleraar Mediarecht en Informatiesamenleving. De toegekende beurs bedraagt 50.000 Euro en stelt docenten in staat hun visie op onderwijs…

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

What is the current relevance of the ethics of counterterrorism and what is the added value of ethics support within the practice of counterterrorism?

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

This thesis aims to investigate the effect of tripartite interaction between microbial inoculants, the plant, and herbivore insects on the rhizosphere microbiome and volatilome. We investigated the rhizosphere microbiome and volatilome of tomato plants exposed to insect herbivory and/or inoculated with…

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.

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

‘We hopen dat ons artikel de mogelijkheden en voordelen laat zien van het gebruik van kunstmatige intelligentie in de quantumfysica om nieuwe ontdekkingen te doen.’ Vedran Dunjko van het Leiden Institute of Advanced Computer Science droeg bij aan een artikel dat vorig jaar verscheen in PNAS. Het artikel…

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

This dissertation is part of a broader research project that revolves around unraveling the evolution of balanced lethal systems.

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.

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.

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

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.
