Associations between the number of children, age at childbirths and prevalence of chronic low back pain: the Nord-Trøndelag Health Study
(Journal article; Peer reviewed, 2020)Background Associations between childbirths and subsequent risk of low back pain (LBP) have not been clarified. Changes in sex hormone levels or lumbar posture during pregnancy may have an impact on LBP later in life. The ... -
Associations of lipoprotein particle profile and objectively measured physical activity and sedentary time in schoolchildren: a prospective cohort study
(Journal article; Peer reviewed, 2022-01-21)Background: Our understanding of the mechanisms through which physical activity might benefit lipoprotein metabolism is inadequate. Here we characterise the continuous associations between physical activity of different ... -
Associations of physical activity and sedentary time with lipoprotein subclasses in Norwegian schoolchildren: The Active Smarter Kids (ASK) study
(Journal article; Peer reviewed, 2019)Background and aims: Physical activity is favourably associated with certain markers of lipid metabolism. The relationship of physical activity with lipoprotein particle profiles in children is not known. Here we examine ... -
Associations of volumes and patterns of physical activity with metabolic health in children: A multivariate pattern analysis approach
(Peer reviewed; Journal article, 2018)Physical activity (PA) favorably affects metabolic health in children, but it is unclear how total volumes versus patterns (bouts and breaks) of PA relate to health. By means of multivariate pattern analysis that can handle ... -
Assumptions, Efficiency and Trust in Non-Interactive Zero-Knowledge Proofs
(Doctoral thesis, 2022-11-04)Vi lever i en digital verden. En betydelig del av livene våre skjer på nettet, og vi bruker internett for stadig flere formål og er avhengig av stadig mer avansert teknologi. Det er derfor viktig å beskytte seg mot ondsinnede ... -
Assuring the integrity of offshore carbon dioxide storage
(Journal article; Peer reviewed, 2022)Carbon capture and storage is a key mitigation strategy proposed for keeping the global temperature rise below 1.5 °C. Offshore storage can provide up to 13% of the global CO2 reduction required to achieve the Intergovernmental ... -
The asymmetric geospace as displayed during the geomagnetic storm on 17 August 2001
(Peer reviewed; Journal article, 2018-11-29)Previous studies have shown that conjugate auroral features are displaced in the two hemispheres when the interplanetary magnetic field (IMF) has a transverse (Y) component. It has also been shown that a BY component is ... -
Asymmetric Ionospheric Equivalent Currents at Magnetic Conjugate Points
(Master thesis, 2017-07-01)In this thesis we will study high-latitude ionospheric equivalent currents at magnetic conjugate points. The following questions have been addressed in this thesis: What solar zenith angle defines the dark-sunlit terminator? ... -
Asymmetrically Varying Guide Field During Magnetic Reconnection: Particle-In-Cell Simulations
(Journal article; Peer reviewed, 2022)Using fully kinetic particle-in-cell modeling, we investigate how magnetic reconnection responds to a varying guide field in one of the inflow regions. We find that the reconnection rate varies significantly when the ... -
Asynchronous Accumulation of Organic Carbon and Nitrogen in the Atlantic Gateway to the Arctic Ocean
(Peer reviewed; Journal article, 2018-11-15)Nitrogen (N) is the main limiting nutrient for biological production in the Arctic Ocean. While dissolved inorganic N (DIN) is well studied, the substantial pool of N bound in organic matter (OM) and its bioavailability ... -
Asynchronous Antarctic and Greenland ice-volume contributions to the last interglacial sea-level highstand
(Peer reviewed; Journal article, 2019-11-06)The last interglacial (LIG; ~130 to ~118 thousand years ago, ka) was the last time global sea level rose well above the present level. Greenland Ice Sheet (GrIS) contributions were insufficient to explain the highstand, ... -
At what cost? Attempting to quantify cost of resistance in bacterium-phage interactions
(Doctoral thesis, 2023-12-15)Biodiversiteten i mikrobielle samfunn er svært stor. Organismene som danner samfunnet må stadig gjøre avveininger mellom ulike karaktertrekk som påvirker deres muligheter for vekst, konkurranse og overlevelse. For å beskrive ... -
Atlantic bluefin tuna spawn early to avoid metabolic meltdown in larvae
(Journal article; Peer reviewed, 2022)To predict shifts in phenology and distribution of organisms we need to understand how survival through early life stages depends on environmental conditions. Here, we present a mechanistic model of development, feeding ... -
Atlantic circulation changes across a stadial-interstadial transition
(Journal article; Peer reviewed, 2023)We combine consistently dated benthic carbon isotopic records distributed over the entire Atlantic Ocean with numerical simulations performed by a glacial configuration of the Norwegian Earth System Model with active ocean ... -
Atlantic halibut reovirus (AHRV): Reservoirs and transmission in culture systems.
(Master thesis, 2015-11-27)The ability to expand within the aquaculture industry is essentially based on reliable production of healthy juvenile fish. In 2013 a new aquareovirus was found to be associated with high juvenile mortality at a Norwegian ... -
The Atlantic inflow across the Greenland-Scotland ridge in global climate models (CMIP5)
(Peer reviewed; Journal article, 2019-05-21)Oceanic heat transport from the North Atlantic to the Arctic through the Nordic Seas is a key component of the climate system that has to be modelled accurately in order to predict, for example, future Arctic sea ice changes ... -
Atlantic inflow and low sea-ice cover in the Nordic Seas promoted Fennoscandian Ice Sheet growth during the Last Glacial Maximum
(Journal article; Peer reviewed, 2023)The Atlantic water inflow into the Nordic Seas has proven difficult to reconstruct for the Last Glacial Maximum. At that time, the Fennoscandian Ice Sheet grew potentially to its maximum extent. Sea-ice free conditions in ... -
Atlantic Meridional Overturning Circulation and δ13C Variability During the Last Interglacial
(Peer reviewed; Journal article, 2020)The Atlantic Meridional Overturning Circulation (AMOC) is thought to be relatively vigorous and stable during Interglacial periods on multimillennial (equilibrium) timescales. However, recent proxy (δ13C benthic) reconstructions ... -
Atlantic Multidecadal Oscillation modulates the impacts of Arctic sea ice decline
(Peer reviewed; Journal article, 2018-03)The Arctic sea ice cover has been rapidly declining in the last two decades, concurrent with a shift in the Atlantic Multidecadal Oscillation (AMO) to its warm phase around 1996/1997. Here we use both observations and model ... -
Atlantic Multidecadal Variability (AMV) in the Norwegian Earth System model
(Master thesis, 2020-06-26)The causes of low-frequency sea surface temperature (SST) variations in the Atlantic, known as Atlantic Multidecadal Variability (AMV), are debated. AMV has climatic impacts on for instance hurricane activity and Sahel ...
