A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

This study is the first to directly relate brain development to sex differences and school performance. The results debunk the myth that brain development is slower in boys.

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

The objective of this study is to better understand the distribution of microplastics in the environment. More specifically, we will quantify the abundance and distribution of microplastics on beaches.

How are links between macro-invertebrate diversity and ecosystem functioning influenced by anthropogenic pressures?

Can we distinguish the effects of pesticides from other abiotic and biotic factors that occur in the field? And how do these factors interact with pesticides?

In February 2014, the Swiss voting population accepted a constitutional initiative that aims at limiting migration through quota and, in the field of employment, national preference.

The lipid matrix in the stratum corneum (SC), the upper layer of the skin, plays a critical role in the skin barrier. The matrix consists of ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs).

The Role and Effectiveness of the G20. In this article, published in The Changing Global Order part of the United Nations University Series on Regionalism book series, author Jaroslaw Kantorowicz discusses the evolution of the G20.

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

The central theme of the NWO-project ‘The Promise of Organization’ is the evolution of political organization during the 19th century. We focus on the enthusiasm, arguments and concrete activities of the organizers as well as the criticism offered by opponents of modern political organization.

The master's specialisation From Cells to Organisms at Leiden University examines the molecular mechanisms underlying health and disease and how cells and organisms adapt to environmental factors.

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

The long term goal of the Biophysical Organic Chemistry/SSNMR group, headed by Prof. Huub de Groot, is to reach an understanding of structure, dynamics and functional mechanisms of membrane proteins and self-organized biological assemblies and to translate this knowledge into new concepts for nano-devices,…

On 1 October 2019, Emile Cammeraat defended his thesis 'Economic Effects of Social Protection'. The doctoral research was supervised by Prof. K.P. Goudswaard and Prof. P.W.C. Koning.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

More than half of Europeans speak two or more languages. Linguist Lisa Cheng investigates the various forms of multilingualism in Europe from a linguistic, cognitive and sociological perspective. She looks for instance at the way in which minority languages influence the standard language of a country,…

This volume challenges the idea that the development of ‘democracy’ is a story of rise and progress at all. It is rather a story of continuous but never completely satisfying attempts of interpreting the rule of the people.

The research in the Biosyn group is focused on the design, synthesis and function of the four major types of biomolecules: nucleic acids, carbohydrates, peptides and lipids and hybrid structures thereof. These biomolecules and their derivatives are used in drug discovery and chemical biology, to develop…

Treatment with special stem cells seems to be a good option for suppressing the immune system in organ transplants. Researchers are trying to learn from processes that take place in the human body during pregnancy.

Throughout all domains of life, from bacteria and archaea to eukaryotes, genomes adopt well-organized three-dimensional structures that can change in space and time to accommodate preferred transcriptional programs for environmental adaptation, the maintenance of cellular identity and differentiation…

Demonstration experiments are a potentially powerful instrument to improve the micro-macro thinking of students in secondary education. Therefore we want to design a practical and generative approach to assist teachers to develop lessons with a demonstration experiment.

My research focusses on site-specific compositional and performance practices of music for organ and electronics and their musical-spatial values.

Our in-house human skin equivalents contain all stratum corneum (SC) barrier lipid classes, but have a reduced level of free fatty acids (FAs), of which a part is mono-unsaturated. These differences lead to an altered SC lipid organization and thereby a reduced barrier function compared to human skin.…
