Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

This book explores the spiritual potential of faith, mysticism and transcendence in answer to the dangers of a mythologised state and the sacro-sanctification of (liberal) democracy and its rule of law.

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

Real-life processes are characterized by dynamics involving time. Examples are walking, sleeping, disease progress in medical treatment, and events in a workflow.

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.

Je hebt ruimte om de opleiding zo in te richten als je…

Material outflows from industrial economies.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

The aim of this project was to estimate emissions from lead products-in-use for the past, the present and the future and assess the development of toxicological risks associated with these products.

Op 11 november 2021 verdedigde Mariana Gkliati het proefschrift 'Systemic Accountability of the European Border and Coast Guard'. Het promotieonderzoek is begeleid door promotoren prof.dr. P. Rodrigues en prof.dr. L. Besselink (UvA).

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

Cryogenic electron microscopy (cryo-EM) is a powerful technique used to visualize the inside of cells and to study specific protein complexes. Within this thesis, I describe the use of various cryo-EM techniques to gain insight into the structural changes of the human pathogen, Vibrio cholerae, as it…

In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…

Traditionally, vaccines are administered intramuscularly using conventional hypodermic needles, which cause pain and distress. Microneedles are very short needles (smaller than 1 mm) that are practically invisible to the naked eye.

Exploring linkages between energy and material use and implications for sustainable development.

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.

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

Possible improvements for the assessment of abiotic depletion in LCA.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

What are the main factors associated with the stranding of the two seal species? What are the factors influencing the prevalence of disease in the two species? Which human-related factors influence the populations of the two seal species?

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Due to the almost complete disappearance of the archive of the Old Dutch West India Company (WIC, 1621-1674) not much is known about the ships and crews of this company. In this project we start the reconstruction of this basic information making use of new digital humanities techniques to extract this…

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.

Het team van wetenschappers binnen TRIXY Expertisecentrum zorgt ervoor dat belangrijke kennis verzameld wordt over kwetsbaarheden bij deze kinderen.

Jonge kinderen, pubers en studenten kunnen door slecht slapen problemen ondervinden bij het leren. Dr. Kristiaan van der Heijden onderzoekt, voor verschillende leeftijdscategorieën, slaapproblemen en oplossingen.

Verschillende groepen mensachtigen leerden waarschijnlijk al veel eerder van elkaar dan tot nu toe werd aangenomen en die kennis werd ook veel verder verspreid. Een studie van archeologen van de Universiteit Leiden naar het gebruik van vuur laat zien dat er 400 duizend jaar geleden al sprake geweest…

Lijm is belangrijk in ons dagelijks leven: het houdt van alles bij elkaar, van schoenen tot mobiele telefoons en zelfs satellieten. Maar lijm is geen moderne uitvinding, de neanderthalers gebruikten het al om handvatten aan hun stenen gereedschap te maken. Leidse onderzoekers ontdekten dat neanderthalers…
