In this study, the inception probability of negative streamers in technical air with 7.5 %vol C5-fluoroketone (C5-FK+air) at 1.0 bar absolute pressure is studied. Similar tests were done for both polarities in technical air (80% N 2 , 20% O 2 ) for comparison with the C5-FK+air results and to...

The structures of atomic clusters and GP-zones preceding precipitation in an Al-0.70Mg-0.85Si-0.15Fe-0.25Mn (wt. %) alloy have been investigated by annular dark field scanning transmission electron microscopy imaging and density functional theory calculations. One analysed condition consisted of one...

To accelerate the decarbonization of the coastal fishing and aquaculture industry, electric as well as hydrogen-electric propulsion vessels are being designed to be deployed in the coastal areas of Norway. The purpose of this paper is to examine the impact of inclusion of fishing vessels charging...

Different clusters of abnormal activities often arise within same temporal domain of drilling operations. This contrasts with employing simplified scenarios, such as anomaly detection models for specific issues like stuck pipe or loss circulation. The dynamic nature of drilling environments demands...

Pollution from lost, abandoned, or discarded fishing gear is recognized as a global nature conservation concern. Longlining with hooks is a commonly applied fishing method in fisheries around the world. The longline gear consists of a mainline with a number of baited hooks that are attached to it by...

Gillnets are among the most common fishing gears worldwide. They are often made of thin twine, which is prone to wear and tear, limiting the lifespan of the gillnet. This increases gillnet turnover, and consequently increased risk of gear discarding, gear loss, ghost fishing and marine pollution...

A good and accessible biomarker is of great clinical value in neuroendocrine tumor (NET) patients, especially considering its frequently indolent nature and long-term follow-up. Plasma chromogranin A (CgA) and 5-hydroxyindoleacetic acid (5-HIAA) are currently used as biomarkers in NET, but their...

Process intensification by cavitation is gaining widespread attention due to the benefits that the intense bubble collapse conditions can provide, yet, several knowledge gaps exist in the modelling of such systems. This work studies the numerical prediction of single bubble dynamics and the various...

CO₂ capture is currently the most mature technological solution to reduce the environmental footprint of several emitters. However, the characterization of innovative blends with reduced energy demand and environmental impact is nowadays a challenge to increase the profitability and deployment of...

As most electrolysis pots in an aluminium potline will have different rates of fluoride losses, while the secondary alumina from the GTC will contain an average fluorine content an imbalance will occur over time leading to instability and require corrections by additions of fluoride or removal of...

A chemical model for the current efficiency (CE) in aluminium cells was used for estimating the maximum attainable CE in industrial cells. The model assumes that the loss in CE is governed by the mass transfer of dissolved metal from the metal surface (cathode) to the bulk of the bath. The mass...
