      Myklebost, Kari Aga; Lähteenmäki, Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-30)
      The history of the Pasvik River, demarcating Norway’s border with Russia in the north is inextricably linked with issues of security and national interests on the one side, and exploitation of natural resources and business interests on the other. This applies not least to the war years, as German warfare in Europe increased the value of the hydropower and the strategic metals of the border region. ...

The Barents ...
    • ON HARDY-TYPE INEQUALITIES AS AN INTELLECTUAL ADVENTURE FOR 100 YEARS 

      Persson, Lars-Erik; Samko, Natasha Gabatsuyevna (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-02)
      We describe some chosen ideas and results for more than 100 years prehistory and history of the remarkable development concerning Hardy-type inequalities. In particular, we present a newer convexity approach, which we believe could partly have changed this development if Hardy had discovered it. In order to emphasize the current very active interest in this subject, we fnalize by presenting some ...

      Whereas hackathons are widespread within and outside academia and have been argued to be a valid pedagogical method for teaching interdisciplinarity, no detailed frameworks or methods are available for conceptualizing and organizing educational hackathons, i.e., hackathons dedicated to best achieving pedagogic objectives. This paper is dedicated to introducing EDUCational Hackathons for learning ...
    • The recombination initiation functions DprA and RecFOR suppress microindel mutations in Acinetobacter baylyi ADP1 

      Liljegren, Mikkel Meyn; Gama, João Alves; Johnsen, Pål Jarle; Harms, Klaus (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-17)
      Short-Patch Double Illegitimate Recombination (SPDIR) has been recently identified as a rare mutation mechanism. During SPDIR, ectopic DNA single-strands anneal with genomic DNA at microhomologies and get integrated during DNA replication, presumably acting as primers for Okazaki fragments. The resulting microindel mutations are highly variable in size and sequence. In the soil bacterium Acinetobacter ...
