Hoe kunnen we het welzijn van mensen maximaliseren, en tegelijkertijd het gebruik van bronnen en de uitstoot van het economische systeem binnen de grenzen van de planeet houden? Het Centrum voor Milieuwetenschappen (CML) wil een globale leider op dit gebied zijn. Ons personeel streeft naar tastbare…

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

This dissertation investigates the energy and material related impacts of the transition towards a low-carbon heating system in the Netherlands, in the context of its 2050 climate and circular economy policy goals.

Predictive maintenance (PdM) is a maintenance policy that uses the past, current, and prognosticated health condition of an asset to predict when timely maintenance should occur.

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.

How can we develop and further improve life cycle impact assessment methods, characterisation factors and normalisation factors?

Politicologen Rebekah Tromble en Michael Meffert (Universiteit Leiden) analyseren waarom sommige media frames aanhouden, terwijl andere frames snel in de vergetelheid geraken. Zij ontwikkelen een methode die is ontleend aan event-history. De casus die Tromble en Meffert bekijken, is de verslaglegging…

Evaluating the environmental consequences of diet changes in the European Union.

Het hoofddoel van dit project is het terugvinden, ordenen en beoordelen van materiaal van de Perzische epische cyclus. Hiermee wordt het vakgebied Iraanse studies verrijkt met de eerste volledige en evenwichtige analyse van vorm en inhoud van de epen binnen de Perzische epische cyclus.

CMLCA is a software tool that supports the technical steps of the Life Cycle Assessment. The focus of the program is on advanced computational aspects of life cycle inventory calculations.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

The main objective of this thesis was to develop clinically relevant survival models for patients with high-grade soft tissue sarcoma of the extremities, in particular the development and validation of prediction models for use in clinical practice.

Op vrijdag 22 april 2022 gingen masterstudenten Forensische Criminologie via een online verbinding met een penitentiaire inrichting in gesprek met twee mannen die een lange detentie uitzitten voor een levensdelict. Het college was onderdeel van het vak Uitzonderlijk Geweld van criminologiedocenten Jennifer…

In this project innovative technology for photovoltaics cells is developed and analysis of ecological and health related risks are explicitly accounted for.

Where and how are critical materials currently used and how can this information be used to develop scenarios about their future demand.

What is the environmental impact of different waste collection systems across Europe? How can the collection be improved when considering collection, sorting, and treatment, as well as use options for secondary materials?

In this thesis we construct an extension associated with the Furstenberg compactification of symmetric space of noncompact type. From this extension we get a cycle in equivariant KK-theory representing the extension. The construction of the extension and the corresponding cycle is a generalization of…

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

How to ensure the environmental and economic benefits of circularity transition at macro-scale?

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

Niet alle duurzame businessmodellen hebben de impact die ze beloven, onthult Leidse milieuwetenschapper Levon Amatuni. Het delen van auto’s of het hergebruiken van telefoons, bijvoorbeeld, hebben een minder grote impact dan gedacht. Amatuni raadt mensen aan om ‘te focussen op echte veranderingen in…

This thesis describes the Multi-site All-Sky CAmeRA (MASCARA), which consists of two small robotic telescope designed to detect exoplanets around the brightest stars in the sky.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

n this thesis we study curves. In the first half, we study moduli spaces of curves and Gromov-Witten invariants, certain kinds of curves counts. We employ logarithmic geometry for this.
