Is individual variation in competitive performance of reared juvenile cod influenced by haemoglobin genotype?
(Peer reviewed; Journal article, 2000)To succeed in scramble competition for food an individual fish will have to have characteristics that allow it to respond rapidly to encountered prey. A trait such as metabolic rate, which has a positive effect on oxygen ... -
“Is it important to consider males while measuring the reproductive potential of a fish stock?”
(Master thesis, 2008)This study explored the paternal contribution to stock reproductive potential in Northeast Arctic (NEA) cod (Gadus morhua L.). An equation for estimating total annual viable sperm production (VSP) was parameterised for NEA ... -
Is it possible to photoperiod manipulate spawning time in planktivorous fish ? A long-term experiment on Atlantic herring
(Journal article; Peer reviewed, 2022)The oocyte development (vitellogenesis) of individual fish is highly dependent upon their physiology which is influenced by both intrinsic and extrinsic factors. Thus, if individuals encounter poor biophysical conditions, ... -
Is the evolution of clutch size limited by incubation ability in shorebirds?
(Master thesis, 2015-06-01)Incubation is a crucial aspect of avian life history where differences in incubation techniques and investments can have long lasting effects on offspring and parental well- being and reproductive success. The factors ... -
Is there a Tornado in Alex's Blood Flow? A Case Study for Narrative Medical Visualization
(Journal article; Peer reviewed, 2022)Narrative visualization advantageously combines storytelling with new media formats and techniques, like interactivity, to create improved learning experiences. In medicine, it has the potential to improve patient understanding ... -
Is there a U-shaped relationship between physical activity in leisure time and risk of chronic low back pain? A follow-up in the HUNT Study
(Peer reviewed; Journal article, 2016-04-11)Background: Physical activity in leisure time is often considered to have favourable effects on the risk of low back pain (LBP), but demonstrating a definite association in epidemiological studies has proven difficult. The ... -
Is there an Association between vitamin D status and risk of chronic low back pain? A nested case-Control analysis in the Nord-Trøndelag Health Study
(Peer reviewed; Journal article, 2017-11-25)Objectives: To explore potential associations between vitamin D status and risk of chronic low back pain (LBP) in a Norwegian cohort, and to investigate whether relationships depend on the season of blood sample collection. ... -
Is there evidence for a 4.2 kaBP event in the northern North Atlantic region?
(Peer reviewed; Journal article, 2019-09-02)We review paleoceanographic and paleoclimatic records from the northern North Atlantic to assess the nature of climatic conditions at 4.2 ka BP, which has been identified as a time of exceptional climatic anomalies in many ... -

Isavsmeltingshistoria ved munningen av Sognefjorden
(Master thesis, 2019-12-20)Målet med oppgåva er å rekonstruere isavsmeltingshistoria på Værlandet, og isdynamikken nord for Sognefjorden ut frå isskuringsobservasjonar. Det er gjort 10Be-eksponeringsdatering frå ni flyttblokker på Værlandet. I tillegg ... -
Isavsmeltningshistorie og havnivåendringer på Værlandet, nord for munningen av Sognefjorden
(Master thesis, 2022-06-01)Forskning på havnivå og isavsmeltinghistorie tilbake i tid er viktig for å forstå hvilke prosesser som har påvirket utviklingsforløpet. Dette kan så brukes til å modellere fremtidige endringer i havnivå. Det er i dette ... -
An isenthalpic formulation for simulating geothermal systems with phase changes
(Chapter; Peer reviewed, 2023)We propose a unified isenthalpic formulation for the equilibrium problem of compositional multiphase mixtures. To solve the equilibrium problem numerically, we used an interior point method with line search and present an ... -
