In this thesis I describe the results of Pulsed Interleaved Excitation and Fluorescence (Cross) Correlation Spectroscopy (PIE-F(C)CS) combined with single-pair Förster Resonance Energy Transfer (spFRET) used to study dynamics in single nucleosomes, which depends on subtle differences in the length of…

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

Curved single crystals provide variable, but well-defined surface structures.

The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

Vitamin A or retinol is essential in embryonic development, the visual cycle and the immune system.

The marine shipping industry is one of the strongest emitters of nitrogen oxides (NOx), a pollutant detrimental to ecology and human health. Over the last 20 years, the pollution produced by power plants, the industry sector, and cars has been decreasing.

Dit project bestudeert sociale afstand - de mate van begrip tussen mensen - in relatie tot het buitenlands beleid van staten. Geeft sociale afstand vorm aan politieke vooroordelen, hulpverhalen en, uiteindelijk, de prioriteiten en beslissingen van het buitenlands beleid van een staat?

Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

This thesis examines the link between simple molecules and the underlying structure and chemistry within protoplanetary disks - the birthplaces of planets.
