This pioneering project will answer this question by examining migrants through the eyes of the courts between 1600 and 1900. It aims to reveal patterns of continuity and change in: 1. Treatment of migrants by criminal courts; 2. Violence and conflicts between migrants and native born.

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

There is concern about the threat that nanoplastics (NPs) may pose to both wildlife and humans. This thesis explores the mechanisms of toxicity of polystyrene nanoparticles (PS-NPs) in chicken embryo.

The overarching clinical aim of this thesis was to improve pharmacological pain management by characterizing the pharmacodynamics of analgesics. This promotion has been awarded the predicate cum laude.

Development of an aggregated impact indicator to measure decoupling.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

Cardiovascular diseases are the primary cause of death in the world with atherosclerosis as primary underlying cause.

In his dissertation Michiel Hooykaas outlines the results of six empirical research projects focused at biodiversity awareness in the Netherlands, specifically people’s knowledge about animals.

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

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.

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

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-…
