This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

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

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

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.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

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

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

Cardiovascular disease is the leading cause of death worldwide.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

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

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

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

Modeling and analysis of cyber-physical systems are still challenging. One reason is that cyber-physical systems involve many different parts (cyber or physical), of different nature (discrete or continuous), and in constant interaction via sensing and actuating.

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

In this thesis we examine certain phenomena in symplectic topology which are related to the theory of isolated singularities.

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

Wat is 'Interaction between Legal Systems' (ILS) en wat betekent het als profileringsgebied binnen de Faculteit der Rechtsgeleerdheid? Hier meer over op de startbijeenkomst van ILS 2.0 op 26 oktober 15.00 – 17.00 in de Grotiuszaal (A051 KOG). De middag wordt afgesloten met een borrel in de Global Lo…

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

The endophytic microbiota is a community of various microorganisms that reside in plant tissue. These microbes are known to promote plant health and resilience, and their members do not simply exist side by side.

This thesis focus on the interaction between M dwarf stellar winds and Galactic cosmic rays and the possible effects on the habitability of exoplanets.

Op 21 februari 2019 verdedigde Ruben Zandvliet zijn proefschrift 'Trade, Investment and Labour: Interactions in International Law'. Het promotieonderzoek is begeleid door promotor prof. dr. N.J. Schrijver.

The primary goal of this research is to deepen our understanding of substrate-enzyme interactions in Glycoside hydrolases. For this purpose, Bacillus circulans xylanase (BcX) has been selected as a well-established model to examine the Michaelis complex and glycosyl-enzyme adduct.

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

Op vrijdag 24 februari zal Prof. Judith Masson (Bristol University), Hoogleraar Rechtssociologie en Fellow bij the UK Academy of Social Science, een lezing geven binnen de Leiden Socio-Legal Series.

The European Council and the European Commission have a similar role in agenda setting. Both place issues on the EU agenda. However, these institutions have distinct designs. They have different political attributes (the European Council has considerably more political authority) and information-processing…
