Osedax mucofloris (Polychaeta, Siboglinidae), a bone-eating marine worm new to Norway
(Peer reviewed; Journal article, 2010)The bone-eating siboglinid polychaete Osedax mucofloris Glover, Källström, Smith & Dahlgren, 2005 is reported from Norwegian waters for the first time. Dense growth was found on bovine bones deposited at 118 meters depth ... -
Osmotic engine converting energy from salinity difference to a hydraulic accumulator by utilizing polyelectrolyte hydrogels
(Journal article; Peer reviewed, 2021)Efficient harvesting of the mixing energy from the salinity gradient between sea and river water remains a challenge. Recently, utilization of the swelling/shrinking properties of hydrogels has been explored as a new means ... -
Ossification of Atlantic cod (Gadus morhua) – Developmental stages revisited
(Peer reviewed; Journal article, 2017-02)In studies of marine larvae, it is common to use days post-hatch as a developmental reference point. We show that age is a poor measure of morphological and physiological development in Atlantic cod. Therefore, we propose ... -
Otolith growth across two generations in Atlantic herring (Clupea harengus)
(Master thesis, 2018-06-27)The Atlantic herring (Clupea harengus) has a wide distribution and a complex metapopulation structure with interactions between the sub-populations. The sub-populations show different adaptations, both genetic and non-genetic, ... -
Otolith growth of herring (Clupea harengus) and sprat (Sprattus sprattus) in the Norwegian fjords
(Master thesis, 2022-06-01)Small pelagic fish play an important role in the ecosystem and are an important economical resource. The two most abundant pelagic fish in the Norwegian fjords are herring and sprat. It is documented that offshore sprat ... -
Otolith structure as indicator of key life history events in Atlantic cod (Gadus morhua)
(Doctoral thesis, 2018-08-27)Otoliths are remarkable recorders of the individual life history, as they can reflect the growth trajectory and may encapsulate marks related to ontogenetic, physiological and environmental events. Visible and chemical ... -
Otolith “spawning zones” across multiple Atlantic cod populations: Do they accurately record maturity and spawning?
(Journal article; Peer reviewed, 2021)Specific changes identified in the otolith macrostructure of Northeast Arctic cod as “spawning zones” are presumed to represent spawning events, but recent experimental studies have challenged this relationship. Because ... -
Ouroboros-E: An efficient Lattice-based Key-Exchange Protocol
(Peer reviewed; Journal article, 2018)The Bit Flipping algorithm is a hard decision decoding algorithm originally designed by Gallager in 1962 to decode Low Density Parity Check Codes (LDPC). It has recently proved to be much more versatile, for Moderate Parity ... -
Outcrop-scale fracture analysis and seismic modelling of a basin-bounding normal fault in platform carbonates, central Italy
(Journal article; Peer reviewed, 2022)Faults are characterized by a complex internal architecture. In carbonates, the geometry, attitude, and distribution of fault-related fractures and subsidiary faults can largely affect the petrophysical properties and hy ... -
Outdoor cycling activity affected by COVID-19 related epidemic-control-decisions
(Journal article; Peer reviewed, 2021-05-06)Aim: The lockdown of sports infrastructure due to the COVID-19 pandemic has substantially shifted people’s physical activity towards public green spaces. With Germany’s lockdown as one of the more severe governmentally ... -
Outlook of solar energy in Europe based on economic growth characteristics
(Peer reviewed; Journal article, 2019)Solar power production in Europe has raised from about 130 MW to 110 GW of installed capacity (corresponding to 90 GWh to 120 TWh in annual electricity generation) during the present century. Together with wind power, it ... -
Output-Sensitive Filtering of Streaming Volume Data
(Peer reviewed; Journal article, 2016-02)Real-time volume data acquisition poses substantial challenges for the traditional visualization pipeline where data enhancement is typically seen as a pre-processing step. In the case of 4D ultrasound data, for instance, ... -
Overlapping Community Detection using Cluster Editing with Vertex Splitting
(Master thesis, 2022-11-21)The problem Cluster Editing with Vertex Splitting models the task of overlapping community detection by yielding a cluster graph wherein a vertex of the input graph may be split so that it is present in several clusters. ... -
Overlapping domain Decomposition and multigrid Methods of inverse Problems
(Department of Applied Mathematics report, Research report, 1997-11) -
Overlapping transcription initiation codes and promoter interpretation in vertebrate development and differentiation
(Doctoral thesis, 2015-01-05)A core promoter is a minimal region sufficient to direct the accurate initiation of transcription. Various core promoter elements have been discovered that recruit and position transcriptional machinery, which then initiates ... -
Overprinting translational domains in passive margin salt basins: insights from analogue modelling
(Peer reviewed; Journal article, 2019-08-02)Current models of gravitational tectonics on the structural styles of salt-influenced passive margins typically depict domains of upslope extension and corresponding downslope contraction separated by a mid-slope domain ... -
The overturning circulation in a changing Arctic
(Doctoral thesis, 2023-11-22)Ved å begrense varmeutvekslingen mellom hav og atmosfære bestemmer sjøisen området for dannelse av dypvann i Arktis. Under økte klimagassutslipp trekker sjøisen seg nordover. Mens nyere studier tyder på at Arktis kan være ... -
