    • Role of Mannose-Binding Lectin and Complement Activation in Venous Thromboembolism 

      Liang, Robin Amanda (Doctoral thesis; Doktorgradsavhandling, 2019-12-17)
      The complement and coagulation systems are two interrelated plasma protein cascades. Evidence from observational and animal studies has proposed a role for the complement system in the development of venous thromboembolism (VTE), but the exact mechanisms remain obscure. The aim of this thesis was to investigate whether activation of the complement system impacts the risk of VTE and to investigate ...
    • Use of simulator training to mitigate risks in arctic shipping operations 

      Røds, Johan-Fredrik; Gudmestad, Ove Tobias (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06)
      Over the recent years, ship traffic in the polar areas has increased. There is reason to believe that this traffic, and especially the cruise traffic, will increase further as the ice retracts towards the poles. There is also reason to believe that with the continued focus and exposure of the Polar Region, the cruise tourism to the region will grow. The increased presence in the polar areas will ...

    • Investigating the effect of class-imbalance on convolutional neural networks for angiodysplasia detection 

      Kaspersen, Oskar Anstein (Master thesis; Mastergradsoppgave, 2019-10-31)
      In this thesis, we look at a deep learning approach to AD detection and focus specifically on the problem of class imbalance, which arises from the fact that lesions only occupy a small part of the images, by analyzing how weighting of the loss function can help address this issue. Balancing the weights of the foreground and background class in the cost-function was found to be crucial to achieve ...

The resistance of dominant tundra species to these season-specific changes, with each season potentially having contrasting effects on their growth and survival, ...
    • Review on Immersion Vaccines for Fish: An Update 2019 

      Bøgwald, Jarl; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-29)
      Immersion vaccines are used for a variety of aquacultured fish to protect against infectious diseases caused by bacteria and viruses. During immersion vaccination the antigens are taken up by the skin, gills or gut and processed by the immune system, where the resulting response may lead to protection. The lack of classical secondary responses following repeated immersion vaccination may partly be ...

      Iversen, Audun; Asche, Frank; Buck, Marcus; Henriksen, Edgar; Stein, Jonas; Svalestuen, Sigbjørn (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-23)
      In several countries, maintaining the population of fisheries dependent communities are of major importance in the fisheries governance system. However, most studies investigating the relationship between fisheries and communities have a qualitative focus on the impact of fisheries policies on the communities. We have access to data on population and key employment indicators of every Norwegian ...
    • Arctic greening and bird nest predation risk across tundra ecotones 

      Ims, Rolf Anker; Henden, John-André; Strømeng, Marita Anti; Thingnes, Anders Voss; Garmo, Mari; Jepsen, Jane Uhd (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-01)
      Alarming global-scale declines of bird numbers are occurring under the changing climate, and species belonging to alpine and Arctic tundra are particularly affected. Increased nest predation appears to be involved4, but the mechanisms linking predation to climate change remain to be shown. Here we test the prediction from food web theory that increased primary productivity (greening of tundra) in a ...
