In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

The primary aim of this project is to recover, order, and assess Persian Epic Cycle material in order to provide the field of Iranian studies with the first comprehensive and balanced analysis of the form and contents of the epics within the Persian Epic Cycle.

Integrating life cycle assessment (LCA) with life cycle costing (LCC) offers the opportunity to simultaneously analyze the environmental and economic aspects of product alternatives, for the integration of which a unified computational has been proposed by Heijungs et al. (2013) [1]. The project aims…

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

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…

Writing an operational guide to the ISO standards for LCA and related sub-projects.

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.

Are there significant differences among the environmental impacts resulting form the production of Asian aquaculture commodities and what are the main causes for these?

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.

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.

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…

Co-ordination Action for Innovation in Life-Cycle Analysis for Sustainability: deepening, broadening and leaping forward the LCA methodology.

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?

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.

The NestWacht project is a Citizen Science collaboration between Science Centre Delft, Naturalis, and the Citizen Science Lab of Leiden University to engage individuals, families and primary schools in Leiden and Delft in scientific research on the impact of climate change on nature in their city, and…

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…

A bike tour is probably not the first thing that comes to mind when thinking about inequality. However, students of a Master Honours Challenge came up with this and other solutions to tackle local inequalities. Creativity and empathy turned out to be useful ingredients.

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 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…
