Gerardu, Th. (author), Dijkstra, J.J. (author), Beeltje, H. (author), van Renesse van Duivenbode, J.A.D. (author)PFOA and PFOS are widely found PFAS components in Dutch topsoils. PFOA was emitted to the atmosphere during 1970-2012 from a fluoropolymers factory, and was deposited mainly within a radius of 50 km. For the first time, detailed concentration-depth profiles of PFOA and PFOS were measured in undisturbed soils down wind of the factory. Three...article 2023

Lubelli, B.A. (author), des Bouvrie, E. (author), Nijland, T.G. (author), Kamat, A. (author)Salt crystallization is a major cause of weathering of mortars, including plasters and renders. In the last decade, the use of mixed-in salt crystallization inhibitors in mortars has been proposed as a solution to improve the durability of this material with respect to salt decay. Laboratory characterization and accelerated weathering tests have...article 2023

Vibration Measurements on a Cable-Stayed Cyclist Arch Bridge for Assessment of the Dynamic BehaviourVerdenius, S.A. (author), Bronkhorst, A.J. (author), Geurts, C.P.W. (author)The new cable-stayed arch bridge Tegenbosch (Eindhoven, the Netherlands) needed an assessment of its dynamic behaviour under wind loading due to its slender design. Because of wind-induced vibration issues on a number of bridges in the Netherlands with similar designs, it was decided to examine if vortex excitation, wind-rain induced vibration,...conference paper 2023

Mehrabani, B.B. (author), Erdmann, J. (author), Sgambi, L. (author), Snelder, M. (author)One of the potential capabilities of Connected and Autonomous Vehicles (CAVs) is that they can have different route choice behavior and driving behavior compared with human Driven Vehicles (HDVs). This will lead to mixed traffic flow with multiple classes of route choice behavior. Therefore, it is crucial to solve the multiclass Traffic...conference paper 2023

Zhou, H. (author), Dorsman, J.L. (author), Mandjes, M. (author), Snelder, M. (author)Nowadays, many cities are intending to reduce the use of private vehicles. Governments are incorporating new mobility services and are adapting their parking policies to promote a more sustainable mobility, as both stra tegies are believed to have the potential to reduce private vehicle use. To understand the effects of these stra tegies, one...article 2023

Schwarz, A.E. (author), Lensen, S.M.C. (author), Langeveld, E. (author), Parker, L.A. (author), Urbanus, J.H. (author)Knowledge on environmental plastic emission and spatial and temporal accumulation is vital for the development of successful mitigation strategies and risk assessments of plastics. In this study, emissions of both micro and macro plastic from the plastic value chain to the environment were assessed on a global level through a mass flow analysis ...article 2023

Thurkow, M. (author), Banzhaf, S. (author), Burler, T. (author), Pultz, J. (author), Schaap, M. (author)Millions of people are exposed to enhanced levels of nitrogen dioxide in urbanized areas, leading to severe health effects. Moreover, nitrogen oxides contribute to the formation of ozone and particulate matter, and as such have wider health related impacts. A substantial reduction of nitrogen oxides may offer considerable health benefits for the...article 2023

Verdenius, S.A. (author), Hengeveld, S.T. (author), Maljaars, J. (author)Train axle load measurements performed between 2012 and 2019 at 87 locations in the Dutch railway network are used to evaluate fatigue of railway bridges. The theoretical fatigue damage using realistic influence lines is determined for the measured loads and for the load model from Eurocode EN 1991-2 Annex D. It appears that this load model is ...article 2023

On the use of common random numbers in activity-based travel demand modeling for scenario comparisonZhou, H. (author), Dorsman, J.L. (author), Mandjes, M. (author), Snelder, M. (author)Activity-based travel demand models provide a high level of detail when modeling complex travel behavior. Since stochastic simulation is used, however, this high level may induce large random fluctuations in the output, necessitating many model reruns to produce reliable output. This may become prohibitive in terms of computation time when...article 2023

(author), Denier van der Gon, H.A.C. (author), Röckmann, T. (author)Natural gas is considered a bridging technology in the energy transition because it produces fewer carbon emissions than coal, for example. However, when leaks exist, methane is released into the atmosphere, leading to a dramatic increase in the carbon footprint of natural gas, as methane is a much stronger greenhouse gas than carbon dioxide....article 2023
