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.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Human vocal communication and music perception represent advanced cognitive skills, seemingly innate and universal. These faculties encompass a range of perceptual and cognitive abilities. Cross-species research sheds light on the origins of musicality by investigating whether these traits are shared…

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

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

De Belgische krant de Standaard heeft onthuld dat er door de Europese Unie er geen informatie meer wordt gedeeld met hulporganisaties over migrantenboten in nood. Dit kan grote gevolgen hebben voor de migranten. Leo Lucassen, hoogleraar migratiegeschiedenis, reageert bij VPRO Bureau Buitenland op het…

Vrijdag 26 augustus 2022 presenteerde het kabinet het nieuwe asielakkoord. Volgens universitair docent Mark Klaassen schuurt het akkoord met het recht.

De beelden van topdrukte bij het opvangcentrum voor asielzoekers in Ter Apel van vorige week lijken het beeld te geven dat Nederland ‘vol’ zit. Maar klopt dit wel? Promovenda Teuntje Vosters praat hier over bij het radioprogramma OVT.

Professor Edwin Bakker, directeur van het Centrum voor Terrorisme & Contraterrorisme heeft zijn nieuwe boek getiteld 'Terrorism and Counterterrorism Studies: Comparing Theory and Practice' bij Leiden University Press uitgebracht.

Op 18 september 2019 verdedigde Huw Llewellyn zijn proefschrift 'An Institutional Perspective on the United Nations Criminal Tribunals: Governance, Independence and Impartiality'. Het promotieonderzoek is begeleid door promotoren prof.dr. N.M. Blokker en prof.dr. L.J. van den Herik.

Antibiotic-resistant bacteria pose a major health threat. Addressing this challenge requires among others the development of new antibacterial compounds. The research described in this thesis focuses on discovering novel antibiotics from soil bacteria, specifically Streptomyces and Paenibacillus.Despite…

In this course, you will explore the organs involved in our food digestion and discover the common causes of abdominal and pelvic pain. The latest graphics and animations will give you new insights and understandings of this part of the body.

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

This thesis addresses the problem of designing performance and energy efficient embedded streaming systems, that is, systems which process a stream of input data coming from the environment and generate a stream of output data going into the environment.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

In order to be able to develop effective medicine and treatments to prevent or cure autoimmune diseases or cancer we need to understand the mechanisms how they arise and what drives their course.Unravelling the fundamental molecular mechanisms influencing the onset and course of diseases such as allergies,…

De Amerikaanse inlichtingendiensten brachten president Nixon ten val, en niet de media zoals het algemene beeld is. Andrew Gawthorpe, onderzoeker op het gebied van diplomatie en de Amerikaanse buitenlandpolitiek, hoopt dat de inlichtingendiensten onder Trump ook de juiste keuze maken.

Een televisiecrew van Euronews kwam naar Leiden om Eugenio Cusumano te interviewen over zijn werk op het gebied van migranten reddingsoperaties in de Middellandse zee. Eugenio is expert op het gebied van international relations.

Fate and toxicity of copper nanoparticles was related to the water chemistry of the environment and pristine size.

This thesis focuses on the synthesis, characterization and performance towards CO2 electroreduction of mono and bi-metallic particles based on p-block metals

This thesis focuses on the role of chemokine receptors CXCR3 and CCR2 in the inflammatory process and infection control using the zebrafish model.

Software development is a complex process. It is important that software products become stable and maintainable assets.

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…
