This study evaluated the combined effect of vegetation and internal water storage (IWS) on evapotranspiration (ET) dynamics in bioretention mesocosms. Twelve mesocosms were arranged under outdoor summer conditions in four configurations: planted/free-drainage (PF), planted/IWS (PI), unplanted/free-drainage …

This study investigates the process conditions required for the scalable production of NPK 5-10-30 using sewage sludge ash as a recycled phosphate source for fertilizer production. Although sewage sludge ash offers strong potential for circular phosphate recovery, its industrial implementation remains …

This thesis investigates the development of internal shear stresses in stiffened-core deep composite pile foundations, with particular focus on the FUNDEX Combi Pile system. These piles are widely used in urban environments due to their vibration-free installation and ability to perform under challenging …

Diatoms are essential in the aquatic ecosystem, especially in estuary systems like the Scheldt Estuary, in which centric diatoms are the dominant phytoplankton and serve as an important food resource for upper trophic levels. The understanding of the population dynamics is therefore an essential element …

Cold spray is an emerging technology that shows great promise for the repair of civil aircraft components. However, certification of such repairs requires a comprehensive evaluation of repair performance, including a detailed assessment of repair strength and the associated failure mechanisms. The present …

This thesis explores how independent editorial formats—specifically “Ich will nicht nach Berlin”— can be used to challenge dominant perceptions of urban spaces and resist the cultural narratives that often accompany gentrification.
