    • Handwritten letters and photo albums linking geoscientists with school classes 

      Stiller-Reeve, Mathew Alexander; Argentino, Claudio; Waghorn, Kate Alyse; Vadakkepuliyambatta, Sunil; Kalenitchenko, Dimitri; Panieri, Giuliana (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-14)
      Was something lost as society moved away from “traditional” media such as handwritten letters and photography and into the digital age? Some of the authors remember this age fondly, and we wanted to see if this fondness could be translated into a science dialogue project with school classes. We designed and carried out a communication process with four classes at different schools across Europe. ...
    • Manifest for mangfold i kunsten 

      Gjærum, Rikke Gürgens (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-09)
      Det mest basale i verden er ofte det man nesten kan kalle det banale. Det vi alle vet, men kanskje likevel ikke makter å artikulere klart. Filosofien hjelper oss med å bryte opp i tankevaner der vi har kjørt oss fast, og bidrar med alternative perspektiver og modeller, slik at virkeligheten kan bli lettere å se.
    • Long-wavelength closures for collisional and neutral interaction terms in gyro-fluid models 

      Wiesenberger, Matthias; Held, Markus (Journal article; Tidsskriftartikkel; Peer reviewed, 2022)
      A collisional gyro-fluid model is presented. The goal of the model is edge and scrape-off layer turbulence. The emphasize in the model derivation heavily lies on "implementability" with today's numerical methods. This translates to an avoidance of infinite sums, strongly coupled equations in time and intricate elliptic operator functions. The resulting model contains the four moments density, parallel ...
    • Sedimentary ancient DNA reveals local vegetation changes driven by glacial activity and climate. 

      Elliott, Lucas Dane; Rijal, Dilli Prasad; Brown, Antony; Bakke, Jostein; Topstad, Lasse; Heintzman, Peter D.; Alsos, Inger Greve (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-07)
      Disentangling the effects of glaciers and climate on vegetation is complicated by the confounding role that climate plays in both systems. We reconstructed changes in vegetation occurring over the Holocene at Jøkelvatnet, a lake located directly downstream from the Langfjordjøkel glacier in northern Norway. We used a sedimentary ancient DNA (sedaDNA) metabarcoding dataset of 38 samples from a ...
    • Feasibility of active handheld NDVI sensors for monitoring of lichen ground cover 

      Erlandsson, Rasmus; Arneberg, Marit Klemetsen; Tømmervik, Hans; Finne, Eirik Aasmo; Nilsen, Lennart; Bjerke, Jarle W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-04)
      Vegetation indices are corner stones in vegetation monitoring. However, previous field studies on lichens and NDVI have been based on passive sensors. Active handheld sensors, with their own light sources, enables high- precision monitoring under variable ambient conditions. We investigated the use of handheld sensor NDVI for monitoring pale lichen cover across three study sites from boreal heathlands ...
    • Sub-arctic mosses and lichens show idiosyncratic responses to combinations of winter heatwaves, freezing and nitrogen deposition 

      Bokhorst, Stef; Bjerke, Jarle W.; Phoenix, Gareth K.; Jaakola, Laura; Mæhre, Hanne; Tømmervik, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-25)
      Arctic ecosystems are increasingly exposed to extreme climatic events throughout the year, which can affect species performance. Cryptogams (bryophytes and lichens) provide important ecosystem services in polar ecosystems but may be physiologically affected or killed by extreme events. Through field and laboratory manipulations, we compared physiological responses of seven dominant sub-Arctic ...
    • Genome-edited salmon: a sustainable and socially acceptable solution to aquaculture? 

      Blix, Torill Pauline Bakkelund (Doctoral thesis; Doktorgradsavhandling, 2023-03-24)
      The Norwegian Atlantic salmon farming industry is halted by challenges related to environmental impact and fish welfare. Some of the issues have been suggested solved by the use of novel genome editing technologies, such as CRISPR, which allows for targeted mutations and speeding up fish breeding. For successful introduction, applications of the technology need to be socially acceptable and contribute ...
    • Physiological Impact of Hypothermia: The Good, the Bad, and the Ugly 

      Tveita, Torkjel; Sieck, Gary C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-22)
      Hypothermia is defined as a core body temperature of <35°C, and as body temperature is reduced the impact on physiological processes can be beneficial or detrimental. The beneficial effect of hypothermia enables circulation of cooled experimental animals to be interrupted for 1–2 h without creating harmful effects, while tolerance of circulation arrest in normothermia is between 4 and 5 min. This ...

    • Shellability and homology of q-complexes and q-matroids 

      Ghorpade, Sudhir R.; Pratihar, Rakhi; Randrianarisoa, Tovohery H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-09)
      We consider a q-analogue of abstract simplicial complexes, called q-complexes, and discuss the notion of shellability for such complexes. It is shown that q-complexes formed by independent subspaces of a q-matroid are shellable. Further, we explicitly determine the homology of q-complexes corresponding to uniform q-matroids. We also outline some partial results concerning the determination of homology ...
    • Killing tensors in Koutras-McIntosh spacetimes 

      Kruglikov, Boris; Steneker, Wijnand Sebastiaan (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-03)
      The Koutras–McIntosh family of metrics include conformally flat pp-waves and the Wils metric. It appeared in a paper of 1996 by Koutras–McIntosh as an example of a pure radiation spacetime without scalar curvature invariants or infinitesimal symmetries. Here we demonstrate that these metrics have no 'hidden symmetries', by which we mean Killing tensors of low degrees. For the particular case of Wils ...
    • Three essays on health and labour market participation 

      Berthung, Espen (Doctoral thesis; Doktorgradsavhandling, 2023-03-23)
      ‘Good health for all’ and ‘employment for all’ are two widely agreed-upon goals in Norwegian politics. Nevertheless, considerable inequalities in health exist, and the economic sustainability of public pensions is pressured by a substantial increase in life expectancy. Improving our understanding of inequalities in health and the relationship between health detriments and labour market participation ...
    • The process of integrating risk management: usefulness, standardisation and adaptation 

      Leonhardsen, Mette; Nilsen, Aud Solveig; Olsen, Odd Einar Falnes (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-25)
      In this paper we analyse how a municipality set out to integrate risk management throughout an organisation with more than 9000 employees in six divisions and over 100 sub-units. An objective was to ensure coherence in risk management related work conducted in various sub-units in the municipality. Being forerunners, those involved had to find their own way. We identify three focus areas of importance ...
