This report investigates the different approaches in the authorization process of GMOs for commercial use in the European Union and the United States of America. Three main aspects are considered and analyzed as potential causes of differences in the authorization process of GMOs for commercial use.…

A neurocognitive investigation of the development of social performance monitoring in youth growing up in stressful versus non-stressful environments

In this dissertation non-parametric Bayesian methods are used in the application of robotic vision.

How can we, together international experts, define future needs of R+D contributions for innovations in the field of risk-based management of chemicals and products in a global perspective using alternative testing strategies to minimize animal tests?

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

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.

Over several decades, a variety of computational methods for drug discovery have been proposed and applied in practice. With the accumulation of data and the development of machine learning methods, computational drug design methods have gradually shifted to a new paradigm, i.e. deep learning methods…

CML-IA is a database that contains characterisation factors for life cycle impact assessment (LCIA) and is easily read by the CMLCA software program.

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

How to ensure the environmental and economic benefits of circularity transition at macro-scale?

Op donderdag 14 december om 16:15 uur verdedigt Michal Diamant haar proefschrift over het budgetrecht van het Nederlandse parlement in het licht van het Europees economisch bestuur. De promotie vindt plaats in het Academiegebouw van de Universiteit Leiden. De promotors zijn Wim Voermans en Michiel van…

In the first part of this thesis we study the geometry of folding patterns.

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

1: What is the relative importance of alfa and beta biodiversity in polar ecosystems, and how does intraspecific variation influence this? 2: How can we use remote sensing to determine functional biodiversity (within communities) in polar ecosystems? 3: Temporal and spatial scales of functional biodiversity:…

This thesis describes a study from both a theoreticaL and an experimental point of view.

Consequences for sediment stability and seston trapping

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

This thesis describes biochemical investigations of glucocerebrosidase (GBA), the lysosomal β- glucosidase that is deficient in Gaucher disease (GD).

Glucocorticoids are potent anti-inflammatory drugs widely used clinically to treat various inflammatory and immune conditions. However, two main clinical problems limit their use. GCs trigger severe side effects and they induce acquired glucocorticoid resistance, especially during chronic systemic treatment…

The molecular mechanisms that instigate a healthy cell to become malignant are fueled by (epi)genetic alterations in so-called driver genes.
