Transition from viscous fingers to foam during drainage in heterogeneous porous media
(Peer reviewed; Journal article, 2023)We investigate the behavior of drainage displacements in heterogeneous porous media finding a transition from viscous fingering to foam-like region. A pore network model incorporating the formation of blobs is adopted to ... -
Species delimitation and phylogenetic relationships of the Prionospio complex (Annelida, Spionidae) in the Northeast Atlantic
(Peer reviewed; Journal article, 2024)The Prionospio complex comprises the most diverse and complex group within the polychaete family Spionidae. The phylogenetic relationships within the group are still poorly understood, and the generic breakdown is unstable. ... -
“We learn it [mathematics] at school so one thinks that one will use it …”: Learners’ beliefs about relevance and importance of learning mathematics.
(Journal article; Peer reviewed, 2023)Denne artikkelen viser at når skoleledere og lærere samhandler i et regionalt utviklingsprosjekt som forutsetter bruk av eksterne kunnskapsressurser som kartleggingsdata og kompetansepakker, forholder de seg til ... -
Effects of Exposure Timing on cyp1a Expression, PAH Elimination, and Lipid Utilization in Lumpfish Embryos Exposed to Produced Water
(Peer reviewed; Journal article, 2023)Intentional discharges of produced water from oil production platforms to the marine environment contain a complex mixture of toxicants, including polycyclic aromatic hydrocarbons (PAHs). Early life stages of fish are ... -
Phosphorus in Palmaria palmata: Uptake, storage and potential recycling in IMTA
(Master thesis, 2023)I fremtiden kommer tilgangen til fosfor å være i stadig begrenset tilgang, siden den blir hentet ut fra begrensede reserver. Fosfor er avgjørende for produksjon av kunstgjødsel for bruk i landbruk, og er derfor på sikt ... -
Norway's Future Forest, warmer and greener? A study on (1) the early recruitment of oak, red elderberry and spruce on post-harvested spruce plantations; (2) Visions, possible pathways and challenges to achieving more deciduous forest through interviews with the public sector.
(Master thesis, 2023)Due to climate change and drought seasons, spruce Picea abies have started to dry out and die. This happened in Moss municipality in 2018, and since then they’ve wanted to find other options than spruce, in particular ... -
Use of Wastewater from Recirculating Aquaculture System (RAS) for Cultivation of Microbial Biofilm Communities
(Master thesis, 2023)Den økende etterspørselen etter bærekraftig mat kan delvis løses ved produksjon av akvatiske arter i resirkulerende akvakultursystemer (RAS). I norsk havbruksnæring blir atlantisk laks (Salmo salar) ofte klekket og kultivert ... -
Leaf it to the professionals: Branching out to restore deciduous forests in southern Norway.
(Master thesis, 2023)While restoration endeavors in Scandinavia and Northern Europe have predominantly concentrated on boreal forests, the often-overlooked boreonemoral forests, sharing similar characteristics, demand equal attention. These ... -

Super selective ammonia separation through multiple-site interaction with ionic liquid-based hybrid membranes
(Peer reviewed; Journal article, 2021)Efficient separation and recovery of ammonia (NH3) is essential for environmental protection and resource utilization. In this work, hybrid membranes for NH3 separation through multiple-site interaction were developed by ... -
Hydrogen sulfide removal from natural gas using membrane technology: a review
(Peer reviewed; Journal article, 2021)Natural gas, having a significantly lower CO2 emission factor than oil and coal when combusted, is accepted as an important transition fuel towards carbon net-zero society. To meet the calorific value requirements (≥34.0 ... -
Membrane fabricated via a facile non-solvent induced microstructure re-arrangement with superior CO<inf>2</inf> separation performances
(Journal article; Peer reviewed, 2023)CO2 capture and storage (CCS) is taken as an immediate solution to mitigate the impactof increasing atmospheric CO2 on global climate change, and CO2 separation using high-performance membranes is considered a green and ... -
Impact of dissolved oxygen removal on solvent degradation for post-combustion CO2 capture
(Peer reviewed; Journal article, 2021)One of the major issues encountered in the Post Combustion CO2 Capture processes is the degradation of the solvent which can be in great part attributed to the presence of oxygen in the solution. The present report focuses ... -
High-performance carbon-capture membranes developed by (non)solvent-induced nanostructural rearrangement in Nafion
(Peer reviewed; Journal article, 2023)Membrane materials exhibiting high CO2 permeability and selectivity are needed for CO2 capture to mitigate global climate change. In this study, Nafion is dissolved in and cast from N-methylpyrrolidone to generate membranes ... -
