Polymer Mixing in a Single Screw Extruder : Part II: Mixing Quantification

J. Buist (Lid Lectoraat); D.J. van Dijk (Lid Lectoraat); C. Hummel (Lid Lectoraat); T.J. Mateboer (Lid Lectoraat)

In this TechForFuture project ‘Polymer Mixing in a Single Screw Extruder’ a method to optimize mixing elements is developed based on numerical simulations (Computational Fluid Dynamics, CFD). A numerical procedure is developed to calculate the flow field in the extruder. By tracing particles in this …

Horizontal gene transfer of an IncP1 plasmid to soil bacterial community introduced by Escherichia coli through manure amendment in soil microcosms

Macedo, G.; Olesen, A.K.; Maccario, L.; Hernandez Leal, L.; Maas, P.M.F. van der (Lector); Heederik, D.; Mevius, D.; Sørensen, S.J.; Schmitt, H.

The quantification and identification of new plasmid-acquiring bacteria in representative mating conditions is critical to characterize the risk of horizontal gene transfer in the environment. This study aimed to quantify conjugation events resulting from manure application to soils and identify the …

An End-to-End Pipeline for Uncertainty Quantification and Remaining Useful Life Estimation: An Application on Aircraft Engines

Kefalas, Marios; van Stein, Bas; Baratchi, Mitra; Apostolidis, Asteris; Bäck, Thomas; Do, Phuc; Michau, Gabriel; Ezhilarasu, Cordelia

Estimating the remaining useful life (RUL) of an asset lies at the heart of prognostics and health management (PHM) of many operations-critical industries such as aviation. Mod- ern methods of RUL estimation adopt techniques from deep learning (DL). However, most of these contemporary tech- niques deliver …

Computed tomography reference values for visceral obesity and increased metabolic risk in a Caucasian cohort

Baggerman, Michelle R; Dekker, Ingeborg M; Winkens, Bjorn; Olde Damink, Steven W M; Weijs, Peter J M (Lectoraat Voeding En Beweging); van de Poll, Marcel C G

BACKGROUND: Visceral obesity is associated with the metabolic syndrome. The metabolic risk differs per ethnicity, but reference values for visceral obesity for body composition analyses using Computed Tomography (CT) scans in the Caucasian population are lacking. Therefore, the aim of this study was …

DNA metabarcoding using nrITS2 provides highly qualitative and quantitative results for airborne pollen monitoring

Marcel Polling (Onderzoeker); Melati Sin (Onderzoeker); Letty de Weger (Onderzoeker); Arjen Speksnijder (Lector); Mieke Koenders (Onderzoeker); Hugo de Boer (Onderzoeker); Barbara Gravendeel (Onderzoeker)

Airborne pollen monitoring is of global socio-economic importance as it provides information on presence and prevalence of allergenic pollen in ambient air. Traditionally, this task has been performed by microscopic investigation, but novel techniques are being developed to automate this process. Among …

Dead space estimates may not be independently associated with 28-day mortality in COVID-19 ARDS

PRoVENT-COVID Study Group

Background: Estimates for dead space ventilation have been shown to be independently associated with an increased risk of mortality in the acute respiratory distress syndrome and small case series of COVID-19-related ARDS. Methods: Secondary analysis from the PRoVENT-COVID study. The PRoVENT-COVID is …
