      Prati, Sebastian; Henriksen, Eirik Haugstvedt; Knudsen, Rune; Amundsen, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-08)
      Changes in abiotic and biotic factors between seasons in subarctic lake systems are often profound, potentially affecting the community structure and population dynamics of parasites over the annual cycle. However, few winter studies exist and interactions between fish hosts and their parasites are typically confined to snapshot studies restricted to the summer season whereas host‐parasite dynamics ...

      Fredriksen, Hege-Beate; Berner, Judith; Subramanian, Aneesh C.; Capotondi, Antonietta (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-22)
      The latest generation of coupled models, the sixth Coupled Models Intercomparison Project (CMIP6), is used to study the changes in the El Niño–Southern Oscillation (ENSO) in a warming climate. For the four future scenarios studied, the sea surface temperature variability increases in most CMIP6 models, but to varying degrees. This increase is linked to a weakening of the east‐west temperature gradient ...

      Coucheron, David Andre (Doctoral thesis; Doktorgradsavhandling, 2021-03-24)
      Chip–based fluorescence imaging is an emerging field where the fluorophores in a sample are excited by the evanescent field generated by waveguides. The aim of this thesis is to explore how waveguide–based excitation can benefit super–resolution optical microscopy, as well as investigate other imaging and spectroscopic applications which can benefit from the same platform. For all imaging and ...
    • Metacognition and decision-making in schizophrenia: Exploring how aberrant processing and representation of uncertainty may explain cognitive-behavioral biases 

      Kreis, Isabel Viola (Doctoral thesis; Doktorgradsavhandling, 2021-04-13)
      The cognitive profile associated with schizophrenia has long been a research subject of interest. A plethora of studies have not only revealed cognitive deficits but also cognitive biases, meaning qualitative deviations in the way information is processed and evaluated. Such biases are for example reflected in findings of diminished metacognitive accuracy, or premature and disadvantageous decision-making. ...

    • Sensitivity Analysis and Case Studies for CO2 Transportation Energy Consumption 

      Jackson, Steven (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      The transportation of CO2 is important to all Carbon Capture and Storage (CCS) projects. Both the infrastructure costs – compressors, pipelines, tanker ships, etc. – and the energy consumed in the compression or liquefaction of CO2 are significant. Understanding how the size, capacity and energy consumption of transportation alternatives varies between projects is therefore important. Modelling ...
    • Reduced grey- and white matter volumes due to unilateral hearing loss following treatment for vestibular schwannoma 

      Heggdal, Peder Olaf Laugen; Larsen, Kristina S.; Brännström, Jonas; Aarstad, Hans Jørgen; Specht, Karsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-03)
      <i>Objective</i> - Previous studies of the consequences of unilateral hearing loss (UHL) on the functional-structural organization of the brain has included subjects with various degrees of UHL. We suggest that the consequences of a total loss of hearing in one ear might differ from those seen in subjects with residual hearing in the affected ear. Thus, the main aim of the present study was to compare ...

    • Modernitet og modernitetskritikk i Emils Durkheims sosiologi 

      Guneriussen, Willy (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-09-07)
      Durkheims forhold til det moderne er preget av ambivalens. Han er kollektivist/holist når det gjelder sosiologiske forklaringer. Samfunnet er en egen realitet og en kraft som påvirker individenes tankeliv, følelser og motiver, om enn ikke i alle detaljer. Men selv om han er metodologisk kollektivist, er det ikke nødvendigvis slik at han også er kollektivist når det gjelder politiske og moralske ...

    • Towards mass cultivation of diatoms as a source of marine lipids 

      Svenning, Jon Brage (Doctoral thesis; Doktorgradsavhandling, 2021-04-23)
      The global demand for the long-chain omega-3 fatty acids EPA and DHA is increasing, and the traditional sources of these fatty acids, fish oils, are no longer able to sustain the demand. This shortage is mainly a result of the surging requirement of EPA and DHA as ingredients in fish feed for aquaculture, and as dietary supplements for human consumption. As a result, there is an increased interest ...
