The constant manipulation of the Dutch delta system and the resulting creation of hard borders between the natural river landscape, the harbor and the city has led to a destabilized delta system(Hein, 2021; Meyer et al., 2015). The spatial and ecological challenges resulting from population growth and the resulting urban growth, as well as...

This paper evaluates the potential of changing the welding force and the compliance of the energy director (ED) to reduce the effects caused by misaligned adherends, which were: increased through-thickness heating, reduced size of welded area and increased heating time. In the methodology that was followed, we welded adherends misaligned by...

This study aims at applying and verifying the MFI-UF method to predict particulate fouling in RO plants. Two full-scale RO plants treating surface water, with average capacity of 800–2000 m<sup>3</sup>/h, were studied. Firstly, the MFI-UF of RO feed and concentrate was measured using 5–100 kDa membranes at same flux applied in the RO plants ...

A palatial building rests by Rue de Bois Sauvage of Brussels, an intimate street located at the exact point where the lower historic city ends and upper bureaucratic city starts. The Palace remains like a parasite of a larger introverted structure that fortifies an entire urban block to hide the offices of the National Bank of Belgium. The...

The identification of arsenic-contamination hotspots in alluvial aquifers is a global-scale challenge. The collection and inventory of arsenic concentration datasets in the shallow-aquifer domain of affected alluvial basins is a tedious and slow process, given the magnitude of the problem. Recent research demonstrates that oxbow-lake...

Over the last 4 decades, remarkable progress has been made in the modelling of casting processes. The development of casting models is well reflected in the proceedings of the 15 Modelling of Casting, Welding and Advanced Solidification Processes (MCWASP) conferences that have been held since 1980. Computer simulations have enabled a better...

This study aimed to quantify the effect of membrane surface porosity on particulate fouling predicted by the MFI-UF method at constant flux. Firstly, the surface porosity of polyethersulfone UF membranes (5–100 kDa) was determined using ultra-high resolution SEM. Thereafter, the MFI-UF was measured using suspensions of polystyrene particles ...

A method is presented to directly measure the mass output of an impaction printer coupled with a spark ablation generator. It is based on a quartz crystal microbalance and shown to be reliable in quantifying mass deposition rate. Here, the method is demonstrated with an Au nanoparticle aerosol synthesized under several spark ablation and...

Phase change materials (PCM) RT-28HC, RT-35HC, and RT-44HC with three different melting temperatures, 29 °C, 36 °C, and 44 °C, with similar thermal properties, are considered. The PCM is oriented from the left to right side of the heat sink in its increasing order. The fins are attached to the heat sink longitudinally, and its orientation...

Natural sediment flocs are fragile and highly heterogeneous aggregates of biogenic and minerogenic material typically with high porosity and low density. In aquatic environments dominated by fine, cohesive or mixed sediments they can dominate suspended sediment flux. Consequently, monitoring and modelling the behaviour, transport and...

Lithium-ion batteries are currently most commonly used in most electronic devices. These batteries are used because of their superiority in gravimetric energy and cyclability compared to other battery technologies. The most common anode used in lithium-ion batteries is currently graphite. Graphite has proven to be a very stable cycling material....

Mechanical air entrapment, void compression and void dissolution are the main mechanisms behind void formation in liquid composite molding. Mechanical air entrapment is induced by the highly non-uniform geometry at the meso- and micro-scale and the heterogeneous properties of the reinforcing material. This results in differences in the velocity...

Energy storage is a critical component in decreasing the unpredictability of<br/>renewable energy. Silicon-air battery is a type of storage technology that potentially has a higher energy density than lithium-ion battery. The silicon-air<br/>battery, on the other hand, must overcome corrosion and passivation reactions in order to discharge...

Among the many cities that lost their status of capital with the Italian unification, Naples is the one that struggled the most to reconcile with its past. With the cholera outbreak of 1874 the criticalities of centuries of uncontrolled urban development under foreign kings rose to the fore of the public opinion of the Kingdom of Italy. Yet, for...

In drinking water treatment plants, multiphase flows are a frequent phenomenon. Examples of such flows are pellet-softening and filter backwashing where liquid-solid fluidisation is applied. A better grasp of these fluidisation processes is needed to be able to determine optimal hydraulic states. In this research, models were developed, and...

Intensified Alkali-Silica Reaction (ASR) damage has occurred on German roadways in recent years, leading to requirements for compulsory pre-construction investigation of aggregate alkali sensitivity using concrete tests with external alkali supply. However, since these tests are time-consuming and cost-intensive, there is interest in replacing...

Cement-based materials in sulfate rich areas will suffer from serious corrosion after semi-immersion. To study the degradation of cement mortars with different water cement ratio (w/c) partially exposed to sulfate solution, the mass change were employed to reveal damage progress. Moreover, porosity, erosion products and SO2 4 - content were...
