Environmental manipulation of land-based farmed Arctic charr; effects on growth, feeding and maturation
(Doctoral thesis, 2014-05-08)Farming of Arctic charr takes mainly place in land-based farms applying intensive rearing methods with relatively high production costs. Depending on local conditions at each site, it is possible to regulate important ... -
Environmental Remediation: Removal of polycyclic aromatic hydrocarbons Dissertation
(Doctoral thesis, 2012-08-17)Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous persistent semi-volatile organic compounds. They are contaminants that are resistant to degradation and can remain in the environment for long periods due to their ... -
Environmental responses to the 9.7 and 8.2 cold events at two ecotonal sites in the Dovre mountains, mid-Norway
(Peer reviewed; Journal article, 2019)We found strong signals of two cooling events around 9700 and 8200 cal yrs. BP in lakes Store Finnsjøen and Flåfattjønna at Dovre, mid-Norway. Analyses included pollen in both lakes, and C/N-ratio, biomarkers (e.g. alkanes ... -
Environmental stressors may cause unpredicted, notably lagged life-history responses in adults of the planktivorous Atlantic herring
(Journal article; Peer reviewed, 2020)Here we challenge traditional views on the direction of change in teleost body condition and reproductive traits in response to abiotic and biotic factors by studying the data-rich, planktivorous Norwegian spring-spawning ... -
Environmental variability in the early rearing environment generates behaviourally flexible cod: implications for rehabilitating wild populations
(Peer reviewed; Journal article, 2005-06-02)The release of hatchery-reared fishes for restoring threatened and endangered populations is one of the most controversial issues in applied ecology. A central issue has been to determine whether releases cause extinction ... -
An environmentally benign and high-rate Appel type reaction
(Journal article; Peer reviewed, 2022)A high rate, selective, and productive Appel type reaction was developed. The method allows for ipso-substitution of the alcoholic hydroxy group with halogens ∈ [Cl, Br, I]. The method demands mild reaction conditions that ... -
Environmentally Friendly Synthesis of Biobased Plastic from Lignin Derived Building Blocks to Replace Poly(ethylene Terephthalate) (PET)
(Master thesis, 2017-12-20)The resources of petroleum are decreasing, and new ways have to be found of producing all the energy and chemicals that today are based on petroleum. An alternative to petroleum is renewable biomass, where lignocellulosic ... -
Environmentally realistic concentrations of chlorinated, brominated, and fluorinated persistent organic pollutants induce the unfolded protein response as a shared stress pathway in the liver of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2023)In the North Sea and North Atlantic coastal areas, fish experience relatively high background levels of persistent organic pollutants. This study aimed to compare the mode of action of environmentally relevant concentrations ... -
Enzymatic and Chemical Syntheses of Vacor Analogs of Nicotinamide Riboside, NMN and NAD
(Journal article; Peer reviewed, 2021)It has recently been demonstrated that the rat poison vacor interferes with mammalian NAD metabolism, because it acts as a nicotinamide analog and is converted by enzymes of the NAD salvage pathway. Thereby, vacor is ... -
Enzymes for Enhanced Oil Recovery (EOR)
(Doctoral thesis, 2011-06-30)Primary oil recovery by reservoir pressure depletion and secondary oil recovery by waterflooding usually result in poor displacement efficiency. As a consequence there is always some trapped oil remaining in oil reservoirs. ... -
Epibenthic megafauna associated with sponge grounds formed by the unique glass sponge Vazella pourtalesii in Emerald Basin, Nova Scotia, Canada
(Master thesis, 2018-06-28)Large, dense aggregations of sponges or “sponge grounds” have seen a surge of scientific interest in recent years. The pivotal ecological functions of sponges may warrant conservation measures that have been neglected in ... -
Epistatic regulation of growth in Atlantic salmon revealed: a QTL study performed on the domesticated-wild interface
(Journal article; Peer reviewed, 2020)Background Quantitative traits are typically considered to be under additive genetic control. Although there are indications that non-additive factors have the potential to contribute to trait variation, experimental ... -
Epistemic Uncertainty Quantification in Deep Learning by the Delta Method
(Doctoral thesis, 2022-05-16)This thesis explores the Delta method and its application to deep learning image classification. The Delta method is a classical procedure for quantifying uncertainty in statistical models, but its direct application to ... -
Epistemic uncertainty quantification in deep learning classification by the Delta method
(Journal article; Peer reviewed, 2022)The Delta method is a classical procedure for quantifying epistemic uncertainty in statistical models, but its direct application to deep neural networks is prevented by the large number of parameters . We propose a low ... -
The EPOS Research Infrastructure: a federated approach to integrate solid Earth science data and services
(Journal article; Peer reviewed, 2022)The European Plate Observing System (EPOS) is a Research Infrastructure (RI) committed to enabling excellent science through the integration, accessibility, use and re-use of solid Earth science data, research products and ... -
eQTLs as causal instruments for the reconstruction of hormone linked gene networks
(Journal article; Peer reviewed, 2022)Hormones act within in highly dynamic systems and much of the phenotypic response to variation in hormone levels is mediated by changes in gene expression. The increase in the number and power of large genetic association ... -
An Equatorial–Extratropical Dipole Structure of the Atlantic Niño
(Peer reviewed; Journal article, 2016)Equatorial Atlantic variability is dominated by the Atlantic Niño peaking during the boreal summer. Studies have shown robust links of the Atlantic Niño to fluctuations of the St. Helena subtropical anticyclone and Benguela ... -
Equilibrium simulations of Marine Isotope Stage 3 climate
(Peer reviewed; Journal article, 2019-06-26)An equilibrium simulation of Marine Isotope Stage 3 (MIS3) climate with boundary conditions characteristic of Greenland Interstadial 8 (GI-8; 38 kyr BP) is carried out with the Norwegian Earth System Model (NorESM). A ... -
Equitable access to cancer patient pathways in Norway – a national registry-based study
(Journal article; Peer reviewed, 2021)Background In 2015, cancer patient pathways (CPP) were implemented in Norway to reduce unnecessary non-medical delay in the diagnostic process and start of treatment. The main aim of this study was to investigate the ... -
