Quantitative assessment of visual microscopy as a tool for microplastic research: Recommendations for improving methods and reporting
(Journal article; Peer reviewed, 2022)Microscopy is often the first step in microplastic analysis and is generally followed by spectroscopy to confirm material type. The value of microscopy lies in its ability to provide count, size, color, and morphological ... -
Quantitative Comparison against Experiments Reveals Imperfections in Force Fields’ Descriptions of POPC-Cholesterol Interactions
(Journal article; Peer reviewed, 2023)Cholesterol is a central building block in biomembranes, where it induces orientational order, slows diffusion, renders the membrane stiffer, and drives domain formation. Molecular dynamics (MD) simulations have played a ... -
Quantitative Comparison of Offshore Sediment Volumes and Onshore Erosion Potential in Norway in the Neogene and Quaternary.
(Master thesis, 2018-06-13)The geodynamic evolution of the Scandinavian topography is the cause of a controversy with several competing hypotheses. Western Scandinavia is characterized by dramatic fjords and high-altitude low-relief surfaces, which ... -
A quantitative description of the West Spitsbergen Current by combining hydrography, altimetry and in-situ current meters
(Master thesis, 2014-06-02)In a warming Arctic Ocean (AO) it is important to study its main source of oceanic heat and salt. Here, seasonal climatological sections of the West Spitsbergen Current (WSC) across 78.83°N have been constructed using ... -
Quantitative diffusion-weighted J-difference spectroscopy of common brain metabolites
(Master thesis, 2021-12-20) -
Quantitative Externalization of Visual Data Analysis Results Using Local Regression Models
(Journal article; Peer reviewed, 2017)Both interactive visualization and computational analysis methods are useful for data studies and an integration of both approaches is promising to successfully combine the benefits of both methodologies. In interactive ... -
Quantitative genetics of breeding coloration in sand lizards; genic capture unlikely to maintain additive genetic variance
(Journal article; Peer reviewed, 2023)Sexual selection on fitness-determining traits should theoretically erode genetic variance and lead to low heritability. However, many sexually selected traits maintain significant phenotypic and additive genetic variance, ... -
Quantitative interpretation using inverse rock-physics modeling on AVO data
(Peer reviewed; Journal article, 2016-08)Quantitative seismic interpretation has become an important and critical technology for improved hydrocarbon exploration and production. However, this is typically a resource-demanding process that requires information ... -

Quantitative Magnetic Resonance Imaging of Tissue Microvasculature and Microstructure in Selected Clinical Applications
(Doctoral thesis, 2022-06-03)This thesis is based on four papers and aims to establish perfusion and diffusion measurements with magnetic resonance imaging (MRI) in selected clinical applications. While structural imaging provides invaluable geometric ... -
Quantitative microbial ecology off the northern Antarctic Peninsula. Antarctic microbial ecology
(Doctoral thesis, 2010-06-22)The waters surrounding the South Shetland Islands, Antarctica, comprise a coastal/oceanic ecosystem that is iron-fertilized naturally from shelf sources of Weddell Sea origin. My thesis incorporates data from an 18-year ... -
Quantitative molecular detection of larval Atlantic herring (Clupea harengus) in stomach contents of Atlantic mackerel (Scomber scombrus) marks regions of predation pressure
(Journal article; Peer reviewed, 2021)Mortality rates in the early life-history stages of fishes are generally high yet identifying the causes remain unclear. Faltering recruitment rates of Atlantic herring (Clupea harengus) in the Norwegian Sea indicate a ... -
Quantitative multiproxy assessment of long-term patterns of Holocene environmental change from a small lake near Abisko, northern Sweden
(Peer reviewed; Journal article, 2002)Quantitative reconstructions are made of Holocene changes in climatic and environmental conditions from analyses of pollen, chironomids and diatoms in identical stratigraphic levels of a sediment core from Vuoskkujávri ... -
Quantitative NMR analysis of the aqueous phase from hydrothermal liquefaction of lignin
(Journal article; Peer reviewed, 2020-08-06)Hydrothermal liquefaction (HTL) of biomass such as lignin could contribute to finding replacements for petroleum, both as a fuel and production of chemicals. The organic phase produced in formic acid assisted HTL of lignin ... -
Quantitative Pore-Scale Analysis of CO2 Foam for CCUS
(Master thesis, 2019-12)This experimental thesis is a part of ongoing projects lead by the Reservoir Physics group at the Department of Physics and Technology, University of Bergen. The main objectives of this thesis were to develop image analysis ... -
Quantitative proteomics analysis of zebrafish exposed to sub-lethal dosages of β-methyl-amino-L-alanine (BMAA)
(Peer reviewed; Journal article, 2016-07-12)The non-protein amino acid β-methylamino-L-alanine (BMAA) is a neurotoxin present in microalgae and shown to accumulate in the food web. BMAA has been linked to the complex neurodegenerative disorder of Guam and to increased ... -
Quantitative reconstruction of precipitation changes on the NE Tibetan Plateau since the Last Glacial Maximum - extending the concept of pollen source area to pollen-based climate reconstructions from large lakes
(Peer reviewed; Journal article, 2014-01-08)Pollen records from large lakes have been used for quantitative palaeoclimate reconstruction, but the influences that lake size (as a result of species-specific variations in pollen dispersal patterns that smaller pollen ... -
