Although various alloy systems have been explored for additive manufacturing (AM) during the past decade, introducing a new alloy remains a challenging task. Most of the materials require iterative builds, for investigating numerous parameters and determining a viable and repeatable process window...

In 2015, the CO₂ Technology Centre Mongstad (TCM DA), operated a test campaign using aqueous monoethanolamine (MEA) solvent at 30 wt%. The main objective was to demonstrate and document the performance of the TCM DA Amine Plant located in Mongstad, Norway. This paper will present several aspects...

B-site cation inter-diffusion in the ABO3 perovskite yttrium-substituted barium zirconate (BZY) was studied at temperatures from 1100 to 1460 °C under reducing and oxidising conditions. The experiments followed two different approaches using Ce as a chemical tracer for Zr. By fitting diffusion...

Proton conducting oxide electrolytes find potential application in proton ceramic fuel cells and electrolyzers operating at intermediate temperatures, e.g. 400–600 °C. However, state-of-the-art proton conducting ceramics based on Y-doped BaZrO3 (BZY) have lower thermal expansion coefficient (TEC...

The direct conversion of methane to methanol has the potential of substantially reducing methane emissions and flaring, as such a process might provide an alternative for remote natural gas locations. In this report, we investigate the performance of a range of Cu-exchanged mordenite zeolites as...

Dsolve (2020-2028) is a centre for research-based innovation - development of biodegradable materials for applications in fisheries and aquaculture. Our research aims to reduce plastic litter and associated problems such as ghost fishing, macro and microplastic caused by the fishery and aquaculture...

Near-shore ship communication is vital to maritime operations, serving as the last-mile communication link between vessels and shore-based infrastructure. Despite its importance, this environment poses pressing challenges. The high density of ships, towering vessels, shore-based buildings, and...

We state and compare four different definitions of magnetic permeability for periodic, artificial media, or metamaterials. The connections among them, and properties in general, are discussed in detail, including causality, passivity, symmetry, asymptotic behavior, and origin dependence. The...

Energy system models provide us with scenarios for the future energy system, supporting our understanding of the impact of societal changes and adopted policies. To front-load the EU’Fit for 55’ package for 2030 and targets of replacing imported natural gas with renewable electricity, the Nordic...

Numerical weather prediction products, radar products, and user terminal observations are used to estimate propagation conditions for the nearest hours lead time. Validation results show good correspondence between predictions and observations using beacon data and user terminal data, but with an...

The higher order multipoles above the electric quadrupole are commonly neglected in metamaterial homogenization. We show that they nevertheless can be significant when the second-order spatial dispersive effects, such as the magnetic response, are considered. In this respect, they can be equally...

The maritime sector is an integral part of the growing blue economy, and accessible and affordable communication is a current goal. However, offshore areas lack adequate wireless connectivity. While Satellite and Very High Frequency (VHF) communication can be used, they come with limitations in cost...

We propose and investigate a bidirectional device-to-device (D2D) transmission scheme that exploits cooperative downlink non-orthogonal multiple access (NOMA) (termed as BCD-NOMA). In BCD-NOMA, two source nodes communicate with their corresponding destination nodes via a relaying node while...

Background: The development of a Digit Triplet Test in the Swahili language is an essential step towards providing accurate hearing assessment for Swahili-speaking populations. Objectives: This study aimed to develop a Digit Triplet Test in Swahili through a two-part procedure consisting of an...

Purpose: Early childhood professionals must accurately identify, refer, and treat children who stutter (CWS) within the scope of their respective roles to ensure each child receives the best possible care. This study aimed to investigate similarities and differences between the practices of...

Bakgrunn: Utviklingsmessig kan stamming ha negative emosjonelle, atferds- og holdningsmessige konsekvenser. Derfor anbefales tidlig identifisering og igangsetting av logopedbehandling så raskt som mulig. Helsesykepleiere på helsestasjonen møter barn på to- og fireårskontroller. Ifølge de...

Expert musicians portray awe-inspiring precision, timing, and phrasing and may be thought to partake in a “hive-mind.” Such a shared musical absorption is characterized by a heightened empathic relation, mutual trust, and a sense that the music “takes over,” thus uniting the performers’ musical...

In the dairy breeding industry, prediction of bull fertility in artificial insemination (AI) is important for efficient and economically sustainable production. However, it is challenging to identify bulls with superior fertility applying conventional in vitro sperm assays. In the present study...

Pressure monitoring in various organs of the body is essential for appropriate diagnostic and therapeutic purposes. In almost all situations, monitoring is performed in a hospital setting. Technological advances not only promise to improve clinical pressure monitoring systems, but also engage toward...
