A phenomenological model for hydration heat evolution of a cemented waste form

This paper presents an extension of an existing phenomenological model for predicting the evolution of hydration heat of a cemented waste form. The cemented waste form is essentially a mixture of blended cement and homogeneous low- and intermediate-level liquid (simulant) radioactive waste (sludge). The motivation stems from the fact that the...

FRET-based dynamic structural biology: Challenges, perspectives and an appeal for open-science practices

Single-molecule FRET (smFRET) has become a mainstream technique for studying biomolecular structural dynamics. The rapid and wide adoption of smFRET experiments by an ever- increasing number of groups has generated significant progress in sample preparation, measurement procedures, data analysis, algorithms and documentation. Several labs...

Experiments and modelling for by-pass pigging of pipelines

(Pipeline Inspection Gauge), which is a cylindrical device that just fits the pipe and propagates through the pipe along with the transport of fluids. While a conventional pig completely seals the pipeline and travels with the same velocity as the production fluids, a by-pass pig has an opening which allows the fluids to partially by-pass the...

Tracking Local Mechanical Impact in Heterogeneous Polymers with Direct Optical Imaging

Structural heterogeneity defines the properties of many functional polymers and it is often crucial for their performance and ability to withstand mechanical impact. Such heterogeneity, however, poses a tremendous challenge for characterization of these materials and limits our ability to design them rationally. Herein we present a practical...

Efficient simulation of one-dimensional two-phase flow with a high-order h-adaptive space-time Discontinuous Galerkin method

One-dimensional models for multiphase flow in pipelines are commonly discretised using first-order Finite Volume (FV) schemes, often combined with implicit time-integration methods. While robust, these methods introduce much numerical diffusion depending on the number of grid points. In this paper we propose a high-order, space-time...

De ontwikkeling van Connected ITS: Wat weten we? Wat weten we nog niet? Hoe vergaren we die kennis?

Nederland investeert fors in slimme mobiliteitsoplossingen. Er zijn de afgelopen paar jaar meer dan vijftig ITS-proefprojecten opgestart, waarvan er zo’n tien Connected ITS betreffen. Deze laatste categorie wordt gezien als the next step in het vakgebied – en zowel overheid als markt investeren dan ook juist hierin. Maar waar staan we eigenlijk...

The transcriptional regulator c2h2 acceleratesmushroom formation in Agaricus bisporus

The Cys2His2 zinc finger protein gene c2h2 of Schizophyllum commune is involved in mushroom formation. Its inactivation results in a strain that is arrested at the stage of aggregate formation. In this study, the c2h2 orthologue of Agaricus bisporus was over-expressed in this white button mushroom forming basidiomycete using Agrobacterium...

Efficient simulation of one-dimensional two-phase flow with a new high-order Discontinuous Galerkin method

One-dimensional models for multiphase flow in pipelines are commonly discretised using first-order Finite Volume (FV) schemes, often combined with implicit time-integration methods. While robust, these methods introduce much numerical diffusion depending on the number of grid points. In this paper we propose a high-order, space-time...
