The book ‘Bestrijdingsmiddelen en Milieu' gives a transparent overview of facts and figures concerning pesticide use in the Netherlands and the impact of pesticides on the environment.

At the moment, over 350.000 chemicals are registered worldwide for production and use. Their application, however, may harm human health and the environment.

In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?

The last decades it is increasingly recognized that acute as well as chronic postoperative pain is an important problem. Treatment and prevention of postoperative pain is a challenge, especially in special patient populations where there is only limited guidance on how to optimally use opioids.

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.

This thesis introduces a relational interaction model and a practical tool for describing, visualising and generating interactive dialogues.

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.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Environmental challenges such as plastic pollution and biodiversity loss require extensive monitoring. Citizen science, in which members of the public participate in scientific research, has therefore become an important approach in environmental science.

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

Artificial intelligence algorithms govern in subtle, yet fundamental ways, the way we live and are transforming our societies. The promise of efficient, low‐cost or ‘neutral’ solutions harnessing the potential of big data has led public bodies to adopt algorithmic systems in the provision of public…

This project uses archaeological, literary and epigraphic evidence to investigate urban development in Roman-period North Africa, compiling this in a GIS-linked database in order to analyse the development of urban settlement spatially over time.

The Economics and Governance specialisation of the Master in Public Administration teaches you to formulate problem-solving approaches to concrete policy issues found at the intersection between economics and public administration. This specialisation is a unique joint offering of the Department of…

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

This thesis describes the use of bioorthogonal proteins in immunological settings. It provides an introduction towards the field of protein modification, which was used throughout the thesis for the expression of proteins containing unnatural amino acids.

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

In this thesis, we developed new ways to use a technique called electroextraction (EE) to extract charged molecules from one liquid into another using an electric field.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

During the development of the (human) body from a single fertilized egg, organs and structures must form. The development and growth of biological forms is called morphogenesis.

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.

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

This thesis describes the design, characterization and application of dextran based crosslinked network.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

In this thesis we use state-of-the-art observations and simulations to provide the best constraints to date on the HVS ejection rate and constraints on the stellar content and dynamics at the GC, including the progenitor binary populations and their star formation history.

There are study programmes at LIACS that offer the opportunity to do an internship or research project, as part of the curriculum.
