This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

The zebrafish is a promising vertebrate model organism in early drug discovery and development.

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.

Inactivating mutations in BRCA1 or BRCA2 genes predispose to several types of cancer.

What are the mechanisms involved in the reconciliation of value conflicts and which interventions are capable of resolving such disputes?

This book contextualizes the use of terror as part of wider movements of political contention, demonstrating that terroristic innovation occurs as part of wider historical processes rather than in a vacuum.

The project investigates how bilingual speakers navigate lexico-syntactic features, including grammatical gender, classifier systems, and the linear order of adjectives and nouns, across Spanish and Chinese in both unilingual and bilingual contexts.

The mission of the Plant Science research programme is to contribute to the sustainable production of high quality crops, flowers and high-value bio-based products. This is realised by generating fundamental knowledge of basic biological processes related to development of plants and their interaction…

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.

PURPOSE: The aim of the study was to develop a cheap and fast method to produce hollow microneedles and an applicator for injecting vaccines into the skin at a pre-defined depth and test the applicability of the system for dermal polio vaccination.

Does Artifical Light at Night (ALAN) disrupt seasonal physiological and behavioral patterns in migrating freshwater fish?

Can international organisations be held responsible for violations of international law by peacekeepers in a peacekeeping operation?

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

The endocannabinoid receptors CB1R and CB2R are involved in a plethora of processes, and consequently are involved in many pathological conditions. Their wide distribution makes the CBRs both an interesting therapeutic target and hard to study.

Mission: The Environmental Biology department aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services. Through this understanding they facilitate strategic management of natural resources by addressing urgent challenges…

Complaints against decisions not to prosecute in socially sensitive issues.

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

Can we link multiple components from herbal extracts with their biological activities?

What is the role of the noradrenergic system in human cognition?

The PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.

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.

Actinobacteria are well known for the production of bioactive natural products, many of which have applications in the fields of human, animal and plant health. Subject of this thesis are the anthracyclines, glycosylated aromatic polyketides with potent anticancer activity.

This thesis investigated the extent to which participation of school students in decision-making processes can be achieved, including through participatory action research (PAR) in teacher education.

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

Does student and teacher gender affect students’ performance and what is the role of gender stereotypes in this relation?

In this thesis, the role of plant-mediated soil legacy effects in shaping aboveground plant-insect interactions was investigated.

Marc Koper’s research focuses on electrocatalysis and electrochemical surface science for sustainable energy and chemistry. Reactions of interest are the redox reactions of the oxygen/hydrogen cycle (water oxidation, hydrogen evolution), the carbon cycle (reduction of carbon dioxide, oxidation of small…

The investigations described in this thesis lay out strategies aimed at advancing antibiotic research and development. The examples presented revolve around two main approaches: understanding drug-target interactions and target identification.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

On the occasion of prof Paul van der Heijden’s stepping down as Rector Magnificus and President of the Executive Board of Leiden University in 2013 the Chair bearing his name on Social Justice was established. It was a “farewell present” of the Leiden University to it’s Rector.

This volume publishes the proceedings of the eleventh annual University of Chicago Oriental Institute Seminar. It uses the sphere of legal institutions as a prism through which to consider gender relations in the ancient world, both in the Near East and beyond. It examines how similar issues were manifested…

From basic science to real-world interventions

This paper addresses the gap that explores how agencies might allocate their personnel so as to maximise performance with the personnel they have.

Sepsis is a life-threatening condition caused by a dysregulated host response to infection, it is associated with significant morbidity, mortality, and with a high financial burden on global healthcare systems. Bacterial infections are the primary cause of sepsis, but the growing prevalence of antimicrobial…

To what extent can digital technologies be considered as authorities?

This article, by Sara Perlstein, explores how perceived social acceptability shapes whether people talk about risks, showing that risk perceptions and conversations are socially negotiated rather than purely individual.

The aim of the RAISE study is to investigate how resilient people respond to stress. Specifically, we will study how key biological systems (HPA-axis, immune system) interact with the brain and social environment in order to facilitate resilient functioning after childhood adversities.

On 19 May 2020, Xuechan Ma defended her thesis 'Moving towards Coexistence and Cooperation: The Spratly Islands and International Law'. The doctoral research was supervised by Prof. N.J. Schrijver.

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

On the occasion of the 80th anniversary of the magna carta of civil aviation, the Convention on International Civil Aviation (Chicago Convention 1944), Professor Steven Truxal has written a leading piece for the European Civil Aviation Conference: The Chicago system: a steadfast legal blueprint for…
