Metapopulation dynamics in Atlantic herring (Clupea harengus L.) along the coast of southern Norway and in the local area of Landvikvannet
(Master thesis, 2013-06)The present thesis provides strong indications for metapopulation dynamics occurring in Atlantic herring (Clupea harengus) along the Norwegian south coast. The evidence stems from analyses of population structure, growth, ... -
Meteorological conditions and cloud effects on surface radiation balance near Helheim glacier and Jakobshavn isbræ (Greenland)using ground-based observations.
(Journal article; Peer reviewed, 2021)The surface radiation budget is an essential component of the total energy exchange between the atmosphere and the Earth’s surface. Measurements of radiative fluxes near/on ice surfaces are sparse in the polar regions, ... -
Meteorological observations in tall masts for the mapping of atmospheric flow in Norwegian fjords
(Journal article; Peer reviewed, 2020)Since 2014, 11 tall meteorological masts have been erected in coastal areas of mid-Norway in order to provide observational data for a detailed description of the wind conditions at several potential fjord crossing sites. ... -
Meter-scale spark X-ray spectrum statistics
(Peer reviewed; Journal article, 2015-11-13)X-ray emission by sparks implies bremsstrahlung from a population of energetic electrons, but the details of this process remain a mystery. We present detailed statistical analysis of X-ray spectra detected by multiple ... -
Methane and carbon dioxide exchange production studies from exposed natural gas hydrate
(Master thesis, 2010)Two laboratory experimental setups have been designed in collaboration with the Reservoir Physics Group at the Department of Physics and Technology. The equipments have been completed and tested. The first experiment was ... -
Methane Hydrate Production Using Mixture of CO2 and N2.
(Master thesis, 2015-06-09)Gas Hydrates (GHs) are naturally occurring solid, crystalline compounds in which natural gas is trapped inside the cage like structures formed by water molecules. Lately a novel technology has been developed for the ... -
Methane Production from Natural Gas Hydrates. Impact of Temperature on CH4 -CO2 Exchange rate in Hydrate Bearing Sandstone
(Master thesis, 2013-06-17)Dissociation by pressure depletion, thermal stimulation and/or injection of inhibitors are three known methods for gas production from natural gas hydrates. Challenges concerning these production methods are water and sand ... -
Methanogenic archaea in Arctic soils from Spitsbergen, Norway (78°N)
(Doctoral thesis, 2006-05-16) -
Methionine deficiency does not increase polyamine turnover through depletion of hepatic S-adenosylmethionine in juvenile Atlantic salmon
(Peer reviewed; Journal article, 2014-10)During the last few decades, plant protein ingredients such as soya proteins have replaced fishmeal in the diets of aquacultured species. This may affect the requirement and metabolism of methionine as soya contains less ... -
Method development and analysis of arsenolipids in marine oils
(Doctoral thesis, 2014-05-19)Arsenic in marine oils is mainly present in the form of lipid-soluble compounds; collectively called arsenolipids. Although total arsenic concentrations in marine oils typically range from 0.2 to 16 mg kg-1 [1-3], knowledge ... -
Method Development for Fatty Acid Analysis by Gas Chromatography with Nitrogen as Carrier Gas

Method development in analysis of cerium dioxide and titanium dioxide nanoparticles with sp-ICP-MS
(Master thesis, 2022-08-01)Denne oppgaven tar for seg analyse av ceriumdioksid og titandioksid ved hjelp av sp-ICP-MS i vann samt. biologiske matriser. En deloppgave er å utvikle en metode for å raffinere størrelsesfordelingen til nanosuspensjoner. -
Method development using LC-MS/MS and LC-IMS-QTOF MS to determine mycotoxins in fish feed samples
(Master thesis, 2020-06-12)Abstract Mycotoxin contamination is an increasing concern in aquafeed industry due to the replacement of marine-based ingredients to plant-based ingredients and climate changes associated with growing mycotoxin contamination ... -
A method for automated de novo design of functional transition-metal compounds
(Doctoral thesis, 2015-10-05)Systematic application of automated design methods in transition metal and organometallic chemistry is hampered by the limitations of computational tools traditionally developed according to organic chemistry formalisms. ... -
Method for cryopreservation of Paramoeba perurans
(Journal article; Peer reviewed, 2020-11-07)Paramoeba perurans causes amoebic gill disease (AGD), which is a major problem in aquaculture worldwide. The parasite can be cultured in vitro, but to this date, no method for long-term storage of the clones exists. In ... -
A method for generating volumetric fault zone grids for pillar gridded reservoir models
(Peer reviewed; Journal article, 2015-08)The internal structure and petrophysical property distribution of fault zones are commonly exceedingly complex compared to the surrounding host rock from which they are derived. This in turn produces highly complex fluid ... -
Method for measuring cooling efficiency ofwater droplets impinging onto hot metal discs
