Adrian Hamers bestudeert de manier waarop hemellichamen om elkaar heen draaien, nu en in de toekomst. Dat blijkt er vaak grilliger aan toe te gaan dan je zou denken. Promotie op 21 juni.

Wetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which…

Clinical development of drugs for central nervous system (CNS) disorders has been particularly challenging and still suffers from high attrition rates.

Marine sponges are important members of reef ecosystems, as they play ecological roles that are essential for the health of the reef.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

Nucleoid associated proteins maintain the architecture of the bacterial chromosome and regulate gene expression, hinting that their role as transcription factors may involve local three-dimensional chromosome re-modelling.

It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

What are the main factors associated with the stranding of the two seal species? What are the factors influencing the prevalence of disease in the two species? Which human-related factors influence the populations of the two seal species?

What is vegetation structure and composition in SFM primary forest, secondary logged over forest (logging FSC certified and logging non certified) in comparison to primary forest? What is avian guild diversity in SFM primary forest, secondary logged over forest (logging FSC certified and logging non…

In 2015, CML published over 70 papers, contributed to the United Nations conference on climate change in Paris, won awards and advised the Dutch government on the safe use of pesticides. CML awarded 11 PhDs and taught students from all over the world how to contribute to sustainability. We wish you…

Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

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…

This article 'Shaping the European External Action Service and its post-Lisbon crisis management structures: an assessment of the EU High Representatives’ political leadership' assesses the role, influence and core aspects of the EU High Representatives’ (HR/VPs) “political leadership” in the context…

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

In order to gain a better insight into the basis of the rapid jasmonic acid (JA)-mediated stress response, an integrated approach using a targeted high-resolution mass spectrometry-based (HRMS) platform, was conducted to monitor the metabolism of JA using the model system of cell suspension cultures…

The idea of citizens and public professionals collaborating to provide public services has widely spread in several countries around the globe. Co-production is often presented as the go-to solution for challenges like a legitimacy crisis of both the government and the market, and financial concerns.…

Streptomyces bacteria are a valuable source of natural products, many of which are used in the clinic or in biotechnology.

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

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.
