Mitogenomics of the suborder Cottoidei (Teleostei: Perciformes): Improved assemblies, mitogenome features, phylogeny, and ecological implications
(Journal article; Peer reviewed, 2022)We determined the mitogenome of Cyclopterus lumpus using a hybrid sequencing approach, and another four closely related species in the Liparidae based on available next-generation sequence data. We found that the mitogenome ... -
Mix Hydrate formation by CH4-CO2 exchange using Phase Field Theory with implicit Thermodynamics
(Peer reviewed; Journal article, 2012)Natural gas hydrates are ice-like structures composed of water and gas (mostly methane) molecules. They are found worldwide and contain huge amounts of bound methane. Therefore, it represent potentially vast and yet untapped ... -
Mixed approach for coupled flow and mechanics in a fractured medium
(Master thesis, 2023-06-01)Denne avhandlingen presenterer en blandet endelig element metode for Biot ligningene for poroelastisitet i et reservoar, sammenkoblet med en blandet formulering av strømning innenfor en sprekk. Sprekken er representert som ... -
A Mixed Approach to the Poisson Problem with Line Sources
(Journal article; Peer reviewed, 2021)In this work we consider the dual-mixed variational formulation of the Poisson equation with a line source. The analysis and approximation of this problem is nonstandard, as the line source causes the solutions to be ... -
Mixed-dimensional auxiliary space preconditioners
(Journal article; Peer reviewed, 2020)This work introduces nodal auxiliary space preconditioners for discretizations of mixed-dimensional partial differential equations. We first consider the continuous setting and generalize the regular decomposition to this ... -
Mixed-dimensional poromechanical models of fractured porous media
(Journal article; Peer reviewed, 2022)We combine classical continuum mechanics with the recently developed calculus for mixed-dimensional problems to obtain governing equations for flow in, and deformation of, fractured materials. We present models in both the ... -
Mixed-stock analysis of Atlantic herring (Clupea harengus): a tool for identifying management units and complex migration dynamics
(Journal article; Peer reviewed, 2023)We developed and validated a mixed-stock analysis (MSA) method with 59 single-nucleotide polymorphisms selected from genome-wide data to assign individuals to populations in mixed-stock samples of Atlantic herring from the ... -
Mixing in the stratified interface of the Faroe Bank Channel overflow: the role of transverse circulation and internal waves
(Peer reviewed; Journal article, 2011-07)The overflow of cold water across the Faroe Bank Channel sill is a significant volume flux of dense water to the North Atlantic Ocean. Using observations of hydrography, current and microstructure from a 1 week cruise and ... -
Mixing of the Storfjorden overflow (Svalbard Archipelago) inferred from denstity overturns
(Journal article, 2004-01-03)Observations were made of the dense overflow from Storfjorden from a survey conducted at closely spaced stations in August 2002. The field data set consists of conventional conductivity-temperature-depth profiles and ... -
Mixing processes in the changing Arctic Ocean
(Doctoral thesis, 2017-08-11)The Arctic has undergone tremendous changes the last decades, including a strong decline in sea ice extent and thickness. The rapid pace of Arctic changes relative to the global changes are known as Arctic amplification, ... -
Mixing rates and vertical heat fluxes north of Svalbard from Arctic winter to spring
(Peer reviewed; Journal article, 2017-06)Mixing and heat flux rates collected in the Eurasian Basin north of Svalbard during the N-ICE2015 drift expedition are presented. The observations cover the deep Nansen Basin, the Svalbard continental slope, and the shallow ... -
Mixture effects of environmental contaminants in Atlantic cod (Gadus morhua) : Combining experimental approaches to study contaminant-induced biological responses
(Doctoral thesis, 2022-01-15)Release of chemicals from anthropogenic activities is considered a substantial threat to the global environment. Marine ecosystems are sinks for accumulation of contaminants, therefore marine organisms are highly susceptible ... -
MLVA genotyping of Moritella viscosa reveals serial emergence of novel, host-specific clonal complexes in Norwegian salmon farming
(Journal article; Peer reviewed, 2023)A Multi-Locus Variable number of tandem repeat Analysis (MLVA) genotyping scheme was developed for the epidemiological study of Moritella viscosa, which causes ‘winter ulcer’ predominantly in sea-reared Atlantic salmon ... -
MMS Measurements of the Vlasov Equation: Probing the Electron Pressure Divergence Within Thin Current Sheets
(Journal article; Peer reviewed, 2019)We investigate the kinetic structure of electron‐scale current sheets found in the vicinity of the magnetopause and embedded in the magnetosheath within the reconnection exhaust. A new technique for computing terms of the ... -
MMS Observations of Multiscale Hall Physics in the Magnetotail
(Journal article; Peer reviewed, 2019)We present Magnetospheric Multiscale mission (MMS) observations of Hall physics in the magnetotail, which compared to dayside Hall physics is a relatively unexplored topic. The plasma consists of electrons, moderately cold ... -
Mn/Fe reduction in sandy soil during degradation of de-icing chemical: Respiration kinetics and prokaryotic community composition
(Master thesis, 2017-08-29)At Oslo airport, Gardermoen, Norway, large quantities of propylene glycol (PG) are used as de-icing fluid during winter, causing high loads of this chemical to infiltrate in surrounding soil during snow melt and increasing ... -
MnDPDP: Contrast agent for imaging and protection of viable tissue
(Journal article; Peer reviewed, 2020-09-10)The semistable chelate manganese (Mn) dipyridoxyl diphosphate (MnDPDP, mangafodipir), previously used as an intravenous (i.v.) contrast agent (Teslascan™, GE Healthcare) for Mn-ion-enhanced MRI (MEMRI), should be reappraised ... -
