The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

The research provides insight into disease behavior in both rural and semi-urban areas in Serengeti in Tanzania.

This thesis focuses on the social dimensions of crane and wetland conservation in rural landscapes in Kenya, Uganda and Zimbabwe.

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

A tidal basin is an inland sea which is almost entirely enclosed by land and connected to the open sea by a tidal inlet. Through the tidal inlets interaction takes place between the tidal basin and the open sea.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

De onderzoeksgroep Organizational & Entrepreneurial Behavior onderzoekt het gedrag van individuen en groepen die in organisaties werken, organisaties starten, of organisaties leiden, met als doel om organisatorische praktijken te informeren.

Neurolaw is een relatief jonge discipline, waarin de impact van de neurowetenschappen op het recht, de juridische praktijk en de criminologie wordt onderzocht. De actuele ontwikkelingen binnen de neurowetenschappen (neurobiologie, -psychologie en -psychiatrie) hebben de betekenis van onderzoek op dit…

Goed werkgeverschap is net als goed werknemerschap een open norm. Daarmee is het onduidelijk en onzeker waar werkgevers zich op dienen te richten en welke rechten (en plichten) werknemers hebben in dat verband. De doelstelling van dit onderzoek is om invulling te geven aan de norm goed werkgeverschap…
