Using EISCAT AB for space debris monitoring
(Research report, 2025)EISCAT radars have made important contributions to the important task of monitoring the space debris population. This has been made possible with access to raw data. Security concerns have at times made access to raw data ... -
Forbrukerfleksibilitet: Om potensialet for å redusere og å flytte strømforbruk hos husholdninger, private og offentlige virksomheter
(Research report, 2025)Denne rapporten undersøker forbrukerfleksibilitet i strømforbruk – altså flytting og reduksjon av strømforbruk, blant husholdninger, bedrifter og offentlige virksomheter. Det belyses hva som kjennetegner strømkunder som ... -
Duration of antibiotic treatment for respiratory tract infections in primary care
(Journal article; Peer reviewed, 2025)Objectives The primary driver of antimicrobial resistance is excessive antibiotic use, posing a global threat to public health. Reducing individual exposure to antibiotics is a key to addressing the problem. This study ... -
Suitability of Real-Time PCR Methods for New Genomic Technique Detection in the Context of the European Regulations: A Case Study in Arabidopsis
(Peer reviewed; Journal article, 2025)PCR methods are widely applied for the detection of genetically modified organisms (GMOs) in Europe, facilitating compliance with stringent regulatory requirements and enabling the accurate identification and quantification ... -
Coherent Modes of Global Coastal Sea Level Variability
(Peer reviewed; Journal article, 2024)Sea level variations in the coastal zone can differ significantly from those in the open ocean and can be highly spatiotemporally coherent in the alongshore direction. Yet, where and how coastal sea levels exhibit variations ... -
The Effects of Predominantly Chemoautotrophic Versus Heterotrophic Biofloc Systems on Nitrifying Bacteria, Planktonic Microorganisms, and Growth of Penaeus vannamei, and Oreochromis niloticus in an Integrated Multitrophic Culture
(Peer reviewed; Journal article, 2024)The aim of this study was to evaluate the effect of predominantly chemoautotrophic and heterotrophic biofloc systems on ammonia-oxidizing bacteria (AOB), nitrite-oxidizing bacteria (NOB), and planktonic microorganisms in ... -
A General Framework to Describe Drilling Process States
(Peer reviewed; Journal article, 2024)Automation and digitalization of drilling require shared knowledge about the state of the drilling process: Is the bit on-bottom drilling or is the string in-slips; is there an overpull or is there a formation fluid influx? ... -
En dyd av nødvendighet? Velgernes syn på samarbeid mellom ytterpartiene i koalisjonsregjeringer
(Peer reviewed; Journal article, 2025)Artikkelen retter søkelyset mot norske velgernes syn på dannelsen av koalisjonsregjeringer. Med data fra Norsk Monitor 2019–2023 undersøker vi holdningene til ytterpartiene i de to hovedalternativene, dvs. Sp- og SV-velgernes ... -
To what extent are wastewater treatment systems a gateway for microplastic particles in the aquatic and terrestrial environments?
(Journal article, 2024)Sewage treatment plants are designed to handle wastes that include several types of pollutants, including microplastics (MPs), which are synthetic polymer materials fragmented to sizes < 5 mm. Investigating the abundance ... -
Lattice Boltzmann simulations of non-Newtonian fluids in annular geometries
(Peer reviewed; Journal article, 2025)A lattice Boltzmann scheme is introduced to model the interaction between a drill string and a non-Newtonian drilling fluid, as fluid–drill–string interactions can give significant force contributions on the drill string. ... -
CICE on a C-grid: New momentum, stress, and transport schemes for CICEv6.5
(Peer reviewed; Journal article, 2024)This article presents the C-grid implementation of the CICE sea ice model, including the C-grid discretization of the momentum equation, the boundary conditions (BCs), and the modifications to the code required to use the ... -
Quantifying sedimentary ’blue carbon’ in relation to canopy cover in the seagrass meadows of Turneffe Atoll, Belize
(Peer reviewed; Journal article, 2024)Introduction: Seagrass sediments are important ‘blue carbon’ reservoirs which store climatically significant quantities of organic carbon (Corg) at the global scale. Seagrass meadows that overly these sediments also provide ... -
Exploration of Training Strategies for a Quantile Regression Deep Neural Network for the Prediction of the Rate of Penetration in a Multi-Lateral Well
(Peer reviewed; Journal article, 2025)In recent years, rate of penetration (ROP) prediction using machine learning has attracted considerable interest. However, few studies have addressed ROP prediction uncertainty and its relation to training data and model ... -
Inefficient transfer of diatoms through the subpolar Southern Ocean twilight zone
(Peer reviewed; Journal article, 2024)The Southern Ocean, a region highly vulnerable to climate change, plays a vital role in regulating global nutrient cycles and atmospheric CO2 via the biological carbon pump. Diatoms, photosynthetically active plankton with ... -
“The Poor Are Hit the Hardest”—Norwegians' Perceptions of Climate (In)Justice
(Peer reviewed; Journal article, 2025)The concept of climate justice is frequently discussed in academic literature focusing on the societal impacts of climate change and climate policy. Less attention has been paid to the public's understanding of the concept. ... -
Robust multi-objective production optimization with CO2 emissions reduction
(Peer reviewed; Journal article, 2025)In this paper, we describe an efficient methodology for simultaneously maximizing the expected profitability of oil field production and minimizing the expected emission of greenhouse gasses associated with the production ... -
A Factor Two Difference in 21st-Century Greenland Ice Sheet Surface Mass Balance Projections From Three Regional Climate Models Under a Strong Warming Scenario (SSP5-8.5)
(Peer reviewed; Journal article, 2024)The Arctic is warming rapidly, significantly reducing the Greenland ice sheet (GrIS) surface mass balance (SMB) and raising its contribution to global sea-level rise. Since these trends are expected to continue, it is ... -
