This thesis discusses several questions regarding the double ramification cycle as a Chow class on the moduli space of stable n-pointed genus g curves using tools from so-called logarithmic geometry.

To contribute to the body of knowledge aiming at a better coverage of ecosystem service assessment in LCA studies, this thesis dives into the challenges of incorporating existing ecosystem service methods within the impact assessment phase of the conventional LCA framework.

The upscaling of Life Cycle Assessment (LCA) data is recognized as one of the main challenges in the ex-ante LCA of emerging technologies. This challenge arises since industrial-scale system specifications for these technologies are unknown and industrial data is lacking.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

A difficulty of studies on chemical kinetics are the reaction time scales and detection of their intermediates.

The main research question of this thesis was: Can nitrogen cycling on dairy farms on peat soil in the Dutch Green Heart area be improved by adapting management to the nitrogen supply from soil and by using other grassland species and crops without affecting milk production?

Public Affairs kennis verbreden, je verrassen met nieuwe inzichten en zoek de verbinding met PA-professionals. Het programma is een samenwerking tussen de Universiteit Leiden (Centre for Professional Learning, CPL) en de Public Affairs Academie, waarbij praktijk en wetenschap met elkaar worden verbo…

Het onderzoek van dit programma is gecentreerd rond dynamische systemen, functionele analyse en hun interactie.

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

Overlevingsanalyse is een onderzoeksgebied dat zich richt op het bestuderen van de tijd tot het optreden van een specifieke uitkomst.

The chemical and structural heterogeneity of toxoid vaccines makes their analysis challenging. However, detailed insights on a molecular level can be obtained by mass spectrometry.

Een vervolg op de bekende Public Affairs-leergang met verdieping voor ervaren Public Affairs-professionals. Je breidt je kennis uit, krijgt nieuwe inzichten en ontmoet collega’s die, net als jij, op een punt staan waarop reflectie en groei centraal komen te staan.

This study seeks to analyse how job stress could be the result of performing administrative tasks

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

Deze leergang is bedoeld voor ervaren (5 jaar of meer) public affairs professionals die op zoek zijn naar verdieping, reflectie en up-to-date willen blijven van de laatste trends en ontwikkelingen binnen hun vakgebied.

De publieke sector is steeds meer een systeem met meerdere niveaus, met interacties tussen publieke en private actoren op nationaal, subnationaal (provincies, regio's) en internationaal niveau en verschillende publieke, semi-publieke en private organisaties die publieke taken uitvoeren. In deze minor…

Arithmetic geometry concerns the number-theoretic properties of geometric objects defined by polynomials. Mathematicians are interested in the rational solutions to these geometric objects.

De masteropleiding Cultural Analysis: Literature and Theory van de Universiteit Leiden richt zich op de studie van literatuur vanuit een vergelijkend en theoretisch perspectief, en onderzoekt de literatuur van een breed spectrum van talen en culturen uit de hele wereld.

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

In unconventional high temperature superconductors, supercurrent vortices are known to spoil the Landau levels. In this thesis the emergence of Landau levels is studied in different types of superconductors: Weyl superconductors, and the Fu-Kane heterostructure.
