Urbanisation is steadily increasing with estimates expecting that 68% of the global population will live in cities by 2050. To accommodate the rural to urban transition, large quantities of land are transformed from natural to urban lands.

GLOBOX is a spatially differentiated multimedia fate, exposure and effect model. It is used for the calculation of spatially differentiated LCA characterisation factors on a global scale.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

Veel docenten in het voortgezet onderwijs houden rekening met verschillen tussen leerlingen. Uit het promotieonderzoek van Saskia Stollman (ICLON) blijkt dat zij hierbij ruimte om te experimenteren en ondersteuning van de school(leiding) nodig hebben.

Wout Broekema benadrukt dat organisaties niet alleen leren van crises, maar ook vergeten, waarbij cruciale kennis en werkwijzen verloren gaan.

This dissertation presents four separate chapters, all striving towards the same goal: to understand dynamic phenomena occurring in dynamic networks and to explore the emergence of equilibrium in a broad sense.

Individuen die werken in de publieke sector zien zichzelf geconfronteerd worden met tegenstrijdige waarden, tegenstrijdige eisen en de noodzaak van het dienen van het soms moeilijk definieerbare publieke belang.

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

Food waste is a defining inefficiency of the modern food system, with profound implications for resource use, climate change, and circular economy transitions. This dissertation examines food waste through two complementary lenses: the prevention of avoidable food waste and the valorization of unavoidable…

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

Fokelien Kootstra verdedigde haar proefschrift op 23 april 2019

In this course, you will explore the organs involved in our food digestion and discover the common causes of abdominal and pelvic pain. The latest graphics and animations will give you new insights and understandings of this part of the body.

Subproject of the ERC project 'Challenging the Liberal World Order from Within: The Invisible History of the United Nations and the Global South'.

Indigenous Latin American artifacts have attracted the interest of Europeans since the earliest moment of contact between Europeans and the Indigenous peoples of the Americas. The ERC-funded BECACO project uses an innovative multidisciplinary framework to investigate the provenance of ethnographic and…

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

Op 10 november 2021 verdedigde Carmel van Niekerk-Jacobs het proefschrift 'Realising the right to reproduce with assistance in South Africa'. Het promotieonderzoek is begeleid door prof.dr. J.J. Sloth-Nielsen en prof.dr. T. Liefaard.

The Economics and Governance specialisation of the Master in Public Administration teaches you to formulate problem-solving approaches to concrete policy issues found at the intersection between economics and public administration. This specialisation is a unique joint offering of the Department of…

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

The origin and evolution of galaxies are closely linked to many different physical phenomena.

Protoplanetary disks are the gas and dust environments where planetary systems form around young stars. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) this thesis analyses the gaseous molecular reservoir, using multiple tracers to resolve the 3D structure of protoplanetary…

This thesis focused on the exploration of monolayer graphene as a membrane in direct methanol fuel cell (DMFC) applications, with improvements achieved through plasma exposure or damage- free chemical functionalization.

Deze week verscheen 'Dutch Post-war Fiction Film through a Lens of Psychoanalysis' van Peter Verstraten bij Amsterdam University Press, het vervolg op Humour and Irony in Dutch Post-war Fiction Film uit 2016.

Sheltering is an immediate human need and determines well-being andhealth.

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

When a star is born in our Galaxy, it is quite likely that it has formed within a massive cluster, which hosts numerous high-mass stars bathing their lower mass neighbours in UV radiation.

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…
