Fate of Lepeophtheirus salmonis and Caligus elongatus During Farmed Salmon Crowding
(Master thesis, 2021)Økt reproduksjon og spredning av Lepeophtheirus salmonis og Caligus elongatus hindrer videre vekst i oppdrettsnæringen og truer den naturlige bestanden av villaks. Trenging vil si å øke tettheten av fisken og er en viktig ... -
The fate of poly- and perfluoroalkyl substances in a marine food web influenced by land-based sources in the Norwegian Arctic
(Peer reviewed; Journal article, 2021)Although poly- and perfluorinated alkyl substances (PFAS) are ubiquitous in the Arctic, their sources and fate in Arctic marine environments remain unclear. Herein, abiotic media (water, snow, and sediment) and biotic media ... -
Fate of Springtime Atmospheric Reactive Mercury: Concentrations and Deposition at Zeppelin, Svalbard
(Peer reviewed; Journal article, 2021)Mid-latitude atmospheric elemental mercury (Hg) emissions undergo extensive oxidation to reactive Hg (RM) compounds during Arctic polar sunrise, resulting in enhanced atmospheric deposition that impacts Arctic marine ... -
The fate of sulfamethoxazole and trimethoprim in a micro-aerated anaerobic membrane bioreactor and the occurrence of antibiotic resistance in the permeate
(Peer reviewed; Journal article, 2023)This study investigates the effects, conversions, and resistance induction, following the addition of 150 μg·L−1 of two antibiotics, sulfamethoxazole (SMX) and trimethoprim (TMP), in a laboratory-scale micro-aerated anaerobic ... -
Father's use of parental leave in organizations with different institutional logics
(Journal article; Peer reviewed, 2019)Although the use of the father’s quota of parental leave has become a majority practice among Norwegian fathers, there is some variation between different groups of fathers. This article explores how male managers in the ... -
Fathers and child welfare services in Norway: self-concept and fathering practice
(Journal article; Peer reviewed, 2017)This article is based on interviews with 15 men whose children have, or have had, involvement with Norwegian child welfare services (CWS). The aim is to contribute to an increased knowledge of their experience of fatherhood, ... -
Fathers' sense of entitlement to shared and ear-marked parental leave
(Journal article; Peer reviewed, 2018)In most countries, parental leave systems consist of several parts with different lengths for fathers and/or mothers. This article compares fathers’ sense of entitlement to two parts of the Norwegian parental leave system ... -
Fatigue Analysis and Design of Mooring Systems. Assessment and comparison of different methods.
(Master thesis, 2015)This master thesis deals with several problems in connection with the evaluation of fatigue damage for mooring lines. One basic problem is to find out the sea states contributing most to the fatigue loads characterized by ... -
