Neijenhuis, T. (author), Le Bussy, Olivier (author), Geldhof, Geoffroy (author), Klijn, M.E. (author), Ottens, M. (author)Protein-based biopharmaceuticals require high purity before final formulation to ensure product safety, making process development time consuming. Implementation of computational approaches at the initial stages of process development offers a significant reduction in development efforts. By preselecting process conditions, experimental...journal article 2024

Tang, Yuchen (author), van Rhijn, Fay (author), Abdelrady, Ahmed (author), Foppen, J.W.A. (author), Bogaard, T.A. (author)Recently, superparamagnetic silica encapsulated DNA microparticles (SiDNAFe) were designed and in various experiments used as a hydrological tracer. We investigated the effect of bed characteristics on the transport behaviour and especially the mass loss of SiDNAFe in open channel injection experiments. Hereto, a series of laboratory...journal article 2023

Hallin, E.C. (author), van IJzendoorn, Christa (author), Homberger, Jan Markus (author), de Vries, S. (author)A model that simulates surface moisture content on sandy beaches for aeolian transport applications is developed and integrated into the aeolian transport model AeoLiS. The moisture content of a thin surface layer (≈2 mm thickness) is computed as a function of wave runup, precipitation, evaporation, percolation, and capillary rise from the...journal article 2023

Chen, Y. (author), Zhang, Y. (author), Šavija, B. (author), Copuroglu, Oguzhan (author)Formulation of quaternary blended system containing ordinary Portland cement or clinker, slag, limestone and calcined clay (LC2) appeared to be a viable approach to developing low-clinker cements without severely sacrificing mechanical performance at later ages. This paper investigates the effect of two material parameters, i.e., LC2-to-slag...journal article 2023

(author)This study evaluated the effects of sludge retention time (SRT) on the membrane filtration performance of an anaerobic membrane bioreactor (AnMBR) fed lipid-rich synthetic dairy wastewater. The membrane filtration performance was evaluated in two AnMBR systems operated at two different SRTs, i.e., 20 and 40 days. For the AnMBR operated at 40...journal article 2022

Li, Ji (author), Hao, Xiaodi (author), Gan, Wei (author), van Loosdrecht, Mark C.M. (author), Wu, Yuanyuan (author)Alginate like extracellular polymers (ALE) recovered from excess sludge have been evaluated as an eco-friendly, cost effective and sustainable alternative to highly valued materials. However, the ALE extraction from flocculent sludge ranges normally from 90 to 190 mg/g VSS, which is only equivalent to the lowest edge of the ALE production...journal article 2022

Ponzoni, Elisa (author), Nocilla, Alessandra (author), Jommi, C. (author)A recent increase in frequency and severity of exceptional climatic events is of concern for the stability of natural and artificial slopes. These undergo continuous evaporation and infiltration cycles, which change the suction distribution and trigger shrinkage, swelling, cracking, and surfi-cial erosion, overall decreasing the soil strength...journal article 2021

Azizi, Arash (author), Musso, Guido (author), Jommi, C. (author)Soils used in earth construction projects are mostly unsaturated, and they undergo frequent drying–wetting cycles (repeated hydraulic loads) due to changes in climatic conditions or variations of the ground water level, particularly at shallow depths. After compaction, changes in water content can significantly influence the hydromechanical...journal article 2020

Baars, S. (author), Andeweg, B.A. (author)To convey information during an oral presentation speakers not only use words, they also gesticulate. Their gestures can be divided into iconic, metaphoric, deictic and beat gestures (McNeill, 1992). Beats (repetitive, short movements) are frowned upon by some presentation skills advisers. Earlier research that focused on short speeches, mostly...journal article 2019

Farajzadeh, R. (author), Bedrikovetsky, P. (author), Lotfollahi, M. (author), Lake, L. W. (author)Physical adsorption and mechanical entrapment are two major causes of polymer retention in porous media. Physical adsorption is considered an equilibrium process and is often modeled by assuming a Langmuir isotherm. The outcome is a steady state pressure response because the permeability reduction is also accounted for by adsorption. However,...journal article 2016
