In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Improvements of weak gravitational lensing shape measurements are presented and some used for data analysis.

Has the industrial sector in China effectively been decarbonizing in recent years, across different regions and subsectors, and is it plausible that it will reduce its CO2 emissions in conformity with national and internationally pledged emission goals?

Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

Description of Development of a low cost technology for in-situ treatment of groundwater for potable and irrigation purposes (TiPOT) (2004 - 2007)

Schaatscoach en bewegingswetenschapper Jac Orie legt al vijftien jaar alles vast over de prestaties van 'zijn' schaatsers. Dankzij datawetenschapper Arno Knobbe, die de verzamelde data op nieuwe manieren doorberekent, kan Orie zijn team nog slimmer trainen in de aanloop naar de Olympische Winterspelen…

The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.

Veel Nederlandse schaatsers en voetballers behoren tot de absolute wereldtop. Toch kunnen ze dankzij slimme statistische analyses wellicht nóg een beetje beter worden. De Universiteit Leiden werkt er samen met Delft en Amsterdam aan.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

Woensdag 14 juli publiceerden Nederlandse astronomen een primeur in vakblad Nature. Het was hen als eersten ter wereld gelukt om isotopen te ontwaren in de damkring van een exoplaneet. Een ontdekking die ons meer kan leren over het ontstaan van planeten. Verschillende media schreven over de bijzondere…

Twee teams met taalwetenschappers deden onafhankelijk van elkaar onderzoek naar de identiteit van ‘Q’, de persoon van wie wordt verondersteld dat die de complottheorie heeft verspreid. Beide studies lijken te wijzen naar hetzelfde duo.

Bestudeer alle aspecten van het menselijk leven in het verleden en plaats je kennis in een breder, historisch perspectief.

Na een voor Frankrijk desastreus verlopen oorlog tegen Pruisen brak in 1871 een opstand uit die de geschiedenis zou ingaan als de Parijse Commune. Op 18 maart van dat jaar bezetten opstandige Parijzenaars de stad. 72 dagen later werden zij in bloedige barricadegevechten verpletterend verslagen. Vele…

The power of personalized nutrition lies in being able to conduct clinical research on healthy people while capturing metabolic markers sensitive to the impact of environmental and metabolic stressors (e.g. diet, changing sex hormones and the menstrual cycle).

This thesis focuses on the X-ray spectral analysis of merging galaxy clusters and the plasma code development for future high-resolution X-ray spectroscopy observations.

Metabolomics has the potential to play a pivotal role in understanding disease onset and progression, and ultimately personalized treatments. One of its major challenges is its large-scale implementation, which is necessary to deal with the high variability of the metabolome. In this work we have developed…
