TV-Stokes And Its Variants For Image Processing
(Doctoral thesis, 2021-03-30)The total variational minimization with a Stokes constraint, also known as the TV-Stokes model, has been considered as one of the most successful models in image processing, especially in image restoration and sparse-data-based ... -
Exploring balanced harvesting by using an Atlantis ecosystem model for the Nordic and Barents seas
(Journal article; Peer reviewed, 2020)“Balanced Harvesting” (BH) has been suggested as a possible strategy to meet the objectives of the Ecosystem Approach to Fisheries, ensuring a high sustainable yield while maintaining ecosystem structure and function. BH ... -
Development of 14 Microsatellite Markers for Zoonotic Tapeworm Dibothriocephalus dendriticus (Cestoda: Diphyllobothriidea)
(Journal article; Peer reviewed, 2020)Dibothriocephalus dendriticus is one of the causative agents of the fish-borne zoonosis diphyllobothriosis. Polymorphic microsatellite markers were originally developed for future genetic studies using microsatellite library ... -
Enhancing pollination is more effective than increased conventional agriculture inputs for improving watermelon yields
(Journal article; Peer reviewed, 2020)Agricultural practices to improve yields in small‐scale farms in Africa usually focus on improving growing conditions for the crops by applying fertilizers, irrigation, and/or pesticides. This may, however, have limited ... -
Understanding the role of organic matter cycling for the spatio-temporal structure of PCBs in the North Sea
(Journal article; Peer reviewed, 2020)Using the North Sea as a case scenario, a combined three-dimensional hydrodynamic-biogeochemical-pollutant model was applied for simulating the seasonal variability of the distribution of hydrophobic chemical pollutants ... -
Structure and Transport of Atlantic Water North of Svalbard From Observations in Summer and Fall 2018
(Journal article; Peer reviewed, 2020)The transport of warm Atlantic Waters north of Svalbard is one of the major heat and salt sources to the Arctic Ocean. The circulation pathways and the associated heat transport influence the variability in the Arctic sea ... -
In vitro digestion method to evaluate solubility of dietary zinc, selenium and manganese in salmonid diets
(Journal article; Peer reviewed, 2020)Background The determination of dietary mineral solubility is one of the main steps in the evaluation of their availability for a given species. Methods This study proposed an in vitro digestion method (acidic and ... -
Acute effects of gas supersaturation on Atlantic salmon smolt in two Norwegian rivers
(Journal article; Peer reviewed, 2020)Total dissolved gas (TDG) supersaturation downstream of hydropower plants may cause gas bubble disease (GBD) and harmful effects in fish. Little is known about tolerance levels of TDG supersaturation on Atlantic salmon ... -
System simulations for the ALICE ITS detector upgrade
(Journal article; Peer reviewed, 2020)Abstract The ALICE experiment at the CERN LHC will feature several upgrades for Run 3, one of which is a new Inner Tracking System (ITS). The ITS upgrade is currently under development and commissioning, and will be ... -
Unravelling the Complex Duplication History of Deuterostome Glycerol Transporters
(Journal article; Peer reviewed, 2020)Transmembrane glycerol transport is an ancient biophysical property that evolved in selected subfamilies of water channel (aquaporin) proteins. Here, we conducted broad level genome (>550) and transcriptome (>300) analyses ... -
Fish for food and nutrition security in Ghana: Challenges and opportunities
(Journal article; Peer reviewed, 2020)Fish is an important dietary source of micronutrients, particularly in low-and middle-income countries. In Ghana, effective management of fish and the fisheries is essential for food, economic and nutrition security and ... -
Physiological and molecular responses to environmental pollutants in Atlantic cod (Gadus morhua) : Characterization of the aryl hydrocarbon receptor signaling pathway and underlying mechanisms of crude oil toxicity
(Doctoral thesis, 2021-03-05)Environmental pollutants are harmful substances that can interfere and disrupt numerous physiological processes. Different cellular defence mechanisms are therefore crucial for both detecting pollutants and coordinate the ... -
Overview of the Norwegian Earth System Model (NorESM2) and key climate response of CMIP6 DECK, historical, and scenario simulations
(Journal article; Peer reviewed, 2020-12)The second version of the coupled Norwegian Earth System Model (NorESM2) is presented and evaluated. NorESM2 is based on the second version of the Community Earth System Model (CESM2) and shares with CESM2 the computer ... -
Antibiotic sensitivity screening of Klebsiella spp. and Raoultella spp. isolated from marine bivalve molluscs reveal presence of CTX-M-producing K. pneumoniae
(Journal article; Peer reviewed, 2020-11)Klebsiella spp. are a major cause of both nosocomial and community acquired infections, with K. pneumoniae being responsible for most human infections. Although Klebsiella spp. are present in a variety of environments, ... -
230Th Normalization: New Insights on an Essential Tool for Quantifying Sedimentary Fluxes in the Modern and Quaternary Ocean
(Journal article; Peer reviewed, 2020-01)230Th normalization is a valuable paleoceanographic tool for reconstructing high‐resolution sediment fluxes during the late Pleistocene (last ~500,000 years). As its application has expanded to ever more diverse marine ... -
Expression and localization of the aryl hydrocarbon receptors and cytochrome P450 1A during early development of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2020)The aryl hydrocarbon receptor (Ahr) is a ligand-activated transcription factor that mediates the toxicity of dioxins and dioxin-like compounds (DLCs) in vertebrates. Two clades of the Ahr family exist in teleosts (Ahr1 and ... -
