State-of-the-art in vitro test systems for nanomaterial toxicity assessment are based on dyes and several staining steps which can be affected by nanomaterial interference. Digital holographic microscopy (DHM), an interferometry-based variant of quantitative phase imaging (QPI), facilitates reliable...

Bakgrunn: Det er et mål at minst 30 prosent av dialysepasienter skal benytte hjemmedialyse. Tett oppfølging fra spesialisthelsetjenesten er vesentlig for å øke pasientenes trygghets- og mestringsfølelse i hjemmebehandlingen. Utgangspunktet for studien var en nyrepoliklinikk der sykepleiernes...

The investment costs of water electrolysis represent one key challenge for the realisation of renewable hydrogen-based energy systems. This work presents a technology cost assessment and outlook towards 2030 for alkaline electrolysers (AEL) and PEM electrolysers (PEMEL) in the MW to GW range taking...

Knowing the position of a moving target can be crucial, for example when localizing a first responder in an emergency scenario. In recent years, ultra wideband (UWB) has gained a lot of attention due to its localization accuracy. Unfortunately, UWB solutions often demand a manual setup in advance...

Fluidization is a well-established and widely used technology in the process industry. The production stability and the large effective contact area between the active substances, resulting in high mass and heat transfer between the phases, are some of the main advantages of fluidization. However...

The objective of this paper is to document experiences of hazard-analysis and risk analysis of automated passenger ferries planned to be operated in sheltered waters in Norway. The operation of autonomous ferries in Norway requires permission from the Norwegian Maritime Authority. This paper aims to...

The railway industry is undergoing modernization and development with increasing use of new technology and digitalisation. In addition to physical security requirements, systems need to be secured against cyberattacks from outsiders. In addition, there are other quality requirements like scalability...

Accelerated testing is widely used in development and pre-qualification of protective organic coatings. In this work 26 coating systems have been investigated in a 2-year C5 atmospheric exposure field test, ISO 9227 salt spray test, ISO 12944-9 cyclic ageing and ISO 16773 electrochemical impedance...

Although Pb(Zr,Ti)O3 (PZT) piezoelectric thin films are finding widespread applications on Earth, it is yet unclear if they are suitable for space-related applications. In space, their long-term reliability is a significant concern due to the difficulties of repairing and replacing malfunctioning...

Security and scalability are core software qualities, which as non-functional aspects share certain characteristics and challenges in how they are approached during software development and operation. Based on expert interviews, this paper explores interactions and dependencies between security and...

Incinerator Bottom Ash (IBA) originates from incineration of municipal waste. The waste contains a fraction of metal where some is aluminium. Unless proper treatment, the bottom ash ends up either in landfills or in best case as building material. Aluminium recovered from IBA can be recycled and...

The sulfuric acid dew point in the flue gas from aluminium electrolysis cells increases with increasing concentrations of sulfur dioxide and water vapour. This represents a potential problem in a future scenario with reduced air draught for increased carbon dioxide capture and heat exchangers for...

Ombruk av bygningsdeler kan bidra til lavere utslipp og mindre avfall fra byggenæringen. I denne artikkelen beskriver vi hva vi kan lære fra seks forbildeprosjekter i Norge, Danmark og Belgia. Rammevilkårene for ombruk varierer mellom landene, og vi vurderer prosjektene med hensyn på 1) type ombruk...

Polymers and polymer composites are negatively impacted by environmental ageing, reducing their service lifetimes. The uncertainty of the material interaction with the environment compromises their superior strength and stiffness. Validation of new composite materials and structures often involves...

The interfacial contact resistance (ICRBPP-GDL) between the bipolar plates (BPPs) and gas diffusion layers (GDLs) plays a major role in proton exchange membrane-fuel cells (PEMFCs) efficiency. Accordingly, materials selection based on ex-situ ICRBPP-GDL determination is a useful tool, provided...

Rotting wood is inhabited by a large diversity of bacteria, fungi, and insects with complex environmental relationships. The aim of this work was to study the composition of the microbiota (bacteria and fungi) in decaying wood from a northwest Spanish forest as a source of industrially relevant...

Global production networks (GPN) research has given limited attention to lead firms’ competitive strategies in emerging project-based industries (PBIs). Informed by the industry life cycle approach, the authors develop a process-sensitive approach that unpacks the black-boxed notion of lead firms...

With the increasing computing and networking capabilities, IoT devices and edge gateways have become part of a larger IoT–edge–cloud computing continuum, where processing and storage tasks are distributed across the whole network hierarchy, not concentrated only in the cloud. At the same time, this...

Geospatial data acquisition of terrains produces huge, noisy and scattered point clouds. An efficient use of the acquired data requires structured and compact data representations. Working directly in a point cloud is often not appealing. To face this challenge, approximation with tensor product B...

Effective coordination is the key to successful agile teams. They rely on frequent interactions and mutual adjustment to manage dependencies between activities, which traditionally has been solved by co-locating the team. As the world is adjusting to post-covid work-life, companies are moving...
