A mud budget of the Wadden Sea and its implications for sediment management

The world’s coasts and deltas are progressively threatened by climate change and human activities. The degree at which coastlines can adapt to these changes strongly depends on the sediment availability. The availability of muddy sediments is however poorly known. This study aims at developing a mud budget for the world’s largest system of...

The Existence and Origin of Multiple Equilibria in Sand-Mud Sediment Beds

The sediment composition of the seabed governs its mobility, hence determining sediment transport and morphological evolution of estuaries and tidal basins. Bed sediments often consist of mixtures of sand and mud, with spatial gradients in the sand/mud content. This study aims at increasing the understanding of processes driving the sediment...

Adaptations in driver deceleration behaviour with automatic incident detection: A naturalistic driving study

Traffic congestion and crash rates can be reduced by introducing variable speed limits (VSLs) and automatic incident detection (AID) systems. Previous findings based on loop detector measurements have revealed that drivers reduce their speeds while approaching traffic congestion when the AID system is active. Notwithstanding these behavioural...

Driver speed compliance following automatic incident detection: Insights from a naturalistic driving study

Automatic incident detection (AID) systems and variable speed limits (VSLs) can reduce crash probability and traffic congestion. Studies based on loop detector data have shown that AID systems decrease the variation in speeds between drivers. Despite the impact on driver behaviour characteristics, most mathematical models evaluating the...

Analysis of naturally-generated corrosion products due to chlorides in 20-year old reinforced concrete: An elastic modulus-mineralogy characterization

The elastic modulus of corrosion product (E_cp) has been reported with significant variations in the literature. This study aims to investigate the E_cp of naturally-generated chloride-induced corrosion products formed in different concrete mixes. Microstructural characterization was conducted through nano-indentation,...

The Structure–Property Correlations in Dry Gelatin Adhesive Films

Gelatins are proteinaceous natural materials that are widely used in areas such as conservation and restoration of artifacts as adhesives and consolidants, in pharmaceutics as drug delivery carriers, and in the food industry as structurants. Herein, type A porcine gelatin adhesive films are prepared via solution casting method and their...

Controlling Healing and Toughness in Polyurethanes by Branch-Mediated Tube Dilation

In this work, we propose the use of regular branching of polyurethanes as a way to regulate chain dynamics and govern crystallization in highly dense hydrogen-bonded systems. As a result, robust and healable polyurethanes can be obtained. To this end, we synthesized a range of aliphatic propane diol derivatives with alkyl branches ranging...

Synthesis of tri-aryl ketone amine isomers and their cure with epoxy resins

Isomeric tri-aryl ketone amines, 1,3-bis(3-aminobenzoyl)benzene (133 BABB), 1,3-bis(4-aminobenzoyl)benzene (134 BABB), and 1,4-bis(4-aminobenzoyl)benzene (144 BABB) are synthesized and cured with diglycidyl ether of bisphenol A and diglycidyl ether of bisphenol F in this work. Differential scanning calorimetry and near-infrared spectroscopy...

Understanding the Effect of the Dianhydride Structure on the Properties of Semi-aromatic Polyimides Containing a Biobased Fatty Diamine

In this work we report the effect of the hard block dianhydride structure on the overall properties of partially bio-based semi-aromatic polyimides. For the study, four polyimides were synthesized using aliphatic fatty dimer diamine (DD1) as the soft block and four different commercially available aromatic dianhydrides as the hard block: 4,4'-(4...

PARAP-levensduurkostenmodel: Besluitvormingsondersteunend instrument voor huisvesting van kantoororganisaties. Handleiding en verantwoording

Transformatie als oplossing voor leegstand: Methoden voor het vaststellen van kansen en risico’s

Ondanks de aantrekkende markt staan nog steeds veel kantoorgebouwen leeg. Een deel hiervan is kansloos voor hergebruik als kantoor. Ombouwen naar nieuwe functies kan een oplossing zijn. Dit artikel bespreekt voor- en nadelen, belicht het standpunt van een aantal ontwikkelaars en presenteert een afwegingsmodel om met behulp van bestaande...
