Manchester, Emily Louise (author), Pirola, S. (author), Pirola, Sergio (author), Mastroiacovo, Giorgio (author), Polvani, Gianluca (author), Pontone, Gianluca (author), Xu, Xiao Yun (author)Aortic valve disease is often treated with bioprosthetic valves. An alternative treatment is aortic valve neocuspidization which is a relatively new reparative procedure whereby the three aortic cusps are replaced with patient pericardium or bovine tissues. Recent research indicates that aortic blood flow is disturbed, and turbulence effects...journal article 2024

Hoekstra, Bas (author)The Dutch construction sector is confronted with a complex and challenging situation. The majority of the infrastructural elements in the Netherlands were built in the 1950s and 60s, which means they are approaching the end of their lifespan. This state, in combination with backlogged maintenance and budget cuts, created a significant and urgent...master thesis 2023

Krousoratis, Konstantinos (author)The majority of existing infrastructure assets are ageing, and sooner or later, they will have reached the end of their service life. As a result, many asset owners are confronted with large-scale replacement projects in the coming decades. Annually, they allocate a significant number of resources, but these budgets are never adequate for...master thesis 2022

Yang, Tao (author), Xie, Rongxian (author), Veljkovic, M. (author)Bolt shear connectors have the advantage of efficient installation and demolition when used in prefabricated composite beams. When bolt shear connectors are damaged in the service period and replaced by new ones, the shear performance of replaced bolts is to be affected by the existing structural damage. This paper investigates the shear...conference paper 2022

Becerra Perez, L.A. (author), Rincón, Luis E. (author), Posada Duque, J.A. (author)There is global pressure to make advanced biofuels profitable. For cellulosic ethanol, three aspects remain as bottlenecks: collection of feedstocks, pretreatment methods, and enzyme production. In this paper, the first aspect is investigated, by addressing the main challenges for the logistics of agricultural residues. A logistic supply...journal article 2022

Willems, Douwe (author)For centuries humanity has been engineering the second largest river system in the Netherlands, the river Meuse system. This resulted in improvements for the shipping and water safety functions, but simultaneously has had a negative impact on other functions of the river Meuse system. Nature and water quality, for example, degraded due to the...master thesis 2021
