Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

Tom Buitelaar dat de micro-niveau discours van internationale organisaties zich imperfect aanpast aan macro-niveau veranderingen, waarbij aanpassing aan macrodruk wordt afgewogen tegen de toewijding aan persistente organisatorische waarden.

Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies. The work in this thesis helps to address this global problem by developing new antibiotic compounds, inspired by the antibacterial mechanisms of the…

In the past decade many population studies have been performed with the Atacama Large Millimeter/submillimeter Array (ALMA) to understand the bulk properties of protoplanetary disks around young stars. These population studies mostly consisted of low mass stars, with relatively few of the disks around…

Op vrijdag 13 en zaterdag 14 september 2024 vond de jaarlijkse bijeenkomst van de European Group of Public Law (EGPL) plaats in Legrena, Griekenland.

Protoplanetary disks are the gas and dust environments where planetary systems form around young stars. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) this thesis analyses the gaseous molecular reservoir, using multiple tracers to resolve the 3D structure of protoplanetary…

Announcement of a new publication by Janneke Verheijen, lecturer at the Institute of Cultural Anthropology and Development Sociology.

Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

As a member of the Research School you can take part in join-in courses. Join-in courses are MA-courses in medieval topics given in set MA-programs of the six participant universities of the Research School. These courses allow you to further specialize in certain topics.

The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

In this dissertation, we work towards an experiment in which we aim to bring a micrometer sized magnet at the tip of a soft cantilever into a superposition.

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…

This thesis pioneers diatom molecular identification and quantification through genome-scale methods, with four key aims: (i) reviewing DNA/RNA sequencing methods in aquatic biomonitoring to highlight their strengths and limitations;

This research project studies the distribution and impact of medieval malaria in the Netherlands.

Dit boek neemt je stapsgewijs mee in het schrijven van een scriptie, met (voornamelijk) een focus op experimenteel onderzoek, dat het meest veel voorkomt. Door de stappen van experimenteel onderzoek in chronologische volgorde op te splitsen en bij elke stap tips te geven, hopen de auteurs enig houvast…

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.

Bij Studeren à la carte of toehoorderschap is er sprake van aanschuifonderwijs: u schuift aan bij een reguliere collegereeks, zonder dat u tentamen aflegt. Na afloop ontvangt u een certificaat van deelname. Hierop staan geen studieresultaten (er is immers geen tentamen afgelegd).

Understanding interactions in quantum many-body systems remains one of the most profound and difficult challenges in condensed matter physics.

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.
