How do social and political developments influence the process of meaning-making in different parts of the world? Why is a particular discourse interpreted in numerous ways depending on the context it is produced and propagated? And how are culture, politics, history, and language intertwined?

Clear English Pronunciation provides students with the tools to effectively communicate in English without centring solely on native-speaker pronunciation models.

Clearance is the most important pharmacokinetic parameter for drug dose selection. Pharmacokinetic information is typically first available in the adult population, and in general only limited pharmacokinetic data are available in children when drugs enter into the market. It is therefore of the utmost…

Could water be present in planet-forming disks before the formation of rocky planets? The James Webb Space Telescope may have found evidence for that. Webb has for the first time observed water in the inner disc around young star where at greater distance, giant planets have already formed. The research…

All the planets in our solar system orbit around the Sun in an ecliptical plane. This is to be expected because our solar system was formed from a so-called protoplanetary disc. PhD candidate Anna Miotello has studied these kinds of discs and how they influence the formation of stars and planets. PhD…
