What are the key issues in conducting LCA of bioenergy systems? What is the environmental sustainability status of second generation bioethanol? How much would the final results of biogenic carbon neutrality assumptions deviate from the true values based on a complete inventory? How to assess the impact…

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.

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

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

Researchers at LED3 are working together with biopharmaceutical company Galapagos to develop software for use in early drug discovery (funded by NWO). This software is able to design molecules with several simultaneously optimized characteristics and will also take prediction reliability into consideration…

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.

Ce livre est une étude pionnière portant sur l’analyse conceptuelle et la traductibilité des termes de maladie dioula jusqu’ici non abordées par les recherches antérieures. Le Dioula est une langue mandé parlée au Burkina Faso. L’étude présente les représentations de la santé, de la maladie et du corps…

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

The objective of this project is to fundamentally improve our understanding of the ways in which science progresses. Empirical studies have used bibliographic metadata to provide relevant insights, but these studies have failed to tell us how science progresses. Supported by computational advances and…

On 1 June 2022, Bruno Braak defended his thesis entitled 'Overcoming ruptures: Zande identity, governance, and tradition during cycles of war and displacement in South Sudan and Uganda (2014-2019).' The doctoral research was supervised by Prof.dr. J.M. Otto, Dr.ir. C.I.M. Jacobs, and Dr. C. Leonardi…

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

Leiden University is 444 years old, and to celebrate 220 cyclists took to the saddle on 11 May and followed the new 44.4 km route around Leiden, The Hague and the surrounding area.

The 2012 crisis in Mali, where the state collapsed and terrorist groups took over the north, came as a surprise to many. Mali had been considered a poster-child for democracy and was judged as considerably more stable than its neighbors by leading quantitative indices of state fragility. This article…

The car we buy is made out of thousands of components, which are produced using different types of materials. These materials need to be sourced from different places, sent to production facilities and assembled. Once the car is dismissed, the components need to be taken care of by either reusing, recycling…
