Greenhouse gas emissions of Norwegian seafoods: From comprehensive to simplified assessment
(Peer reviewed; Journal article, 2021)The seafood sector is facing difficulties to meet the increasing demand for product greenhouse gas emission (GHG) assessments. We quantified GHGs of important seafood products of Norway, the world's second largest seafood ... -
Offshore field experiments with in-situ burning of oil: Emissions and burn efficiency
(Peer reviewed; Journal article, 2021)In situ burning (ISB) is an oil spill response technique including ignition and burning to remove oil on the water surface. The technique rapidly and effectively removes large portions of the oil. However, the combustion ... -
Common workflows for computing material properties using different quantum engines
(Peer reviewed; Journal article, 2021)The prediction of material properties based on density-functional theory has become routinely common, thanks, in part, to the steady increase in the number and robustness of available simulation packages. This plurality ... -
An improved modelling framework for strength and work hardening of precipitate strengthened Al–Mg–Si alloys
(Peer reviewed; Journal article, 2022)A modelling framework for the strength and work hardening contributions in age hardened Al–Mg–Si alloys is presented. The modelling work is based on transmission electron microscopy (TEM) measurements of the needle-shaped ... -
Experimental verification of the elastic response in a numeric model of a composite propeller blade with bend twist deformation
(Peer reviewed; Journal article, 2021)Adaptive composite propeller blades showing bend twist behaviour have received increasing interest from hydrodynamic and structural engineers. When exposed to periodic loading conditions, such propellers can be designed ... -
Studying GPI zones in Al-Zn-Mg alloys by 4D-STEM
(Peer reviewed; Journal article, 2021)A new methodology has been developed to study the fine details of GP zones in age-hardenable aluminium alloys. It is complementary to atomic resolution high-angle annular dark-field scanning transmission electron microscopy ... -
Detecting minute amounts of nitrogen in GaNAs thin films using STEM and CBED
(Peer reviewed; Journal article, 2021)Nitrogen (N) is a common element added to GaAs for band gap engineering and strain compensation. However, detection of small amounts of N is difficult for electron microscopy as well as for other chemical analysis techniques. ... -
Bycatch reduction in the deep-water shrimp (Pandalus borealis) trawl fishery by increasing codend mesh openness
(Peer reviewed; Journal article, 2021)In most trawl fisheries, drag forces tend to close the meshes in large areas of diamond mesh codends, negatively affecting their selective potential. In the Barents Sea deep-water shrimp (Pandalus borealis) trawl fishery, ... -
Optimal ship lifetime fuel and power system selection
(Peer reviewed; Journal article, 2021)Alternative fuels and fuel-flexible ships are often seen as promising solutions for achieving significant greenhouse gas reductions in shipping. We formulate the selection of alternative fuels and corresponding ship power ... -
New insights into submarine tailing disposal for a reduced environmental footprint: Lessons learnt from Norwegian fjords
(Peer reviewed; Journal article, 2022)Submarine tailing disposal (STD) in fjords from land-based mines is common practice in Norway and takes place in other regions worldwide. We synthesize the results of a multidisciplinary programme on environmental impacts ... -
X-ray absorption, X-ray diffraction and electron microscopy study of spent cobalt based catalyst in semi-commercial scale Fischer-Tropsch synthesis
(Peer reviewed; Journal article, 2014)Calcined, reduced and spent Co-Re/γ-Al2O3 catalysts for Fischer–Tropsch synthesis (FTS) were characterized and compared. Co-K-edge and Re-LIII-edge X-ray absorption near edge structure (XANES), X-ray powder diffraction ... -
Assessing cyber threats for storyless systems
(Peer reviewed; Journal article, 2021)A proper assessment of potential cyber threats is vital for security decision-making. This becomes an even more challenging task when dealing with new system designs and industry sectors where there is little or no historical ... -
Screening, Monitoring, and Remediation of Legacy Wells to Improve Reservoir Integrity for Large-Scale CO2 Storage—An Example From the Smeaheia Structure in the Northern North Sea
(Peer reviewed; Journal article, 2022)Carbon capture and storage (CCS) is an inevitable action to achieve CO2 emission reduction targets including becoming net-zero by 2050. Increased efforts are therefore required to identify suitable locations for large-scale ... -
Robust adaptive backstepping DP control of ROVs
(Peer reviewed; Journal article, 2022)Dynamic positioning is an important control feature for an underwater remotely operated vehicle. This paper presents a nonlinear dynamic positioning controller suited for application to vehicles with model uncertainties, ... -
Optical measurement of tissue perfusion changes as an alternative to electrocardiography for heart rate monitoring in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2021)Background: Welfare challenges in salmon farming highlights the need to improve understanding of the fish’s response to its environment and rearing operations. This can be achieved by monitoring physiological responses ... -
On the temperature dependence of the cyclic compression behaviour of a thermoplastic vulcanizate elastomer
(Peer reviewed; Journal article, 2022)Effects of temperature on the uniaxial cyclic compression of a polypropylene based thermoplastic vulcanizate were studied in the range −40 °C–100 °C. The effect of temperature on the stress level was similar to that on the ... -
Exposure to low environmental copper concentrations does not affect survival and development in Atlantic cod (Gadus morhua) early life stages
(Peer reviewed; Journal article, 2021)In this study we investigated potential impacts of Cu exposure at low, environmentally relevant, concentrations on early live stages of Atlantic cod (Gadus morhua). Cod embryos and larvae were exposed to 0.5 μg/L (low), ... -
Assessment of random wave energy dissipation due to submerged aquatic plants in shallow water using deep water wave conditions
(Peer reviewed; Journal article, 2021)This article addresses the random wave energy dissipation due to submerged aquatic plants in shallow water based on deep water wave conditions including estimation of wave damping. The motivation is to provide a simple ... -
Techno-economic assessment of blue and green ammonia as energy carriers in a low-carbon future
(Peer reviewed; Journal article, 2022)Ammonia is an industrial chemical and the basic building block for the fertilizer industry. Lately, attention has shifted towards using ammonia as a carbon-free energy vector, due to the ease of transportation and storage ... -
Industrial production of activated carbon using circular bioeconomy principles: Case study from a Romanian company
(Peer reviewed; Journal article, 2022)This work discloses an industrial multi-ton scale methodology implemented by a Romanian company (Explocom GK) to use bio-wastes to produce biochar, demonstrating a case of bio-economy circularity associated with economic ...
