    • Introduction of Mysis relicta (Mysida) reduces niche segregation between deep-water Arctic charr morphs 

      Knudsen, Rune; Eloranta, Antti; Siwertsson, Anna; Paterson, Rachel A.; Power, Michael; Sandlund, Odd Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-26)
      Niche diversification of polymorphic Arctic charr can be altered by multiple anthropogenic stressors. The opossum-shrimp (<i>Mysis relicta</i>) was introduced to compensate for reduced food resources for fish following hydropower operations in Lake Limingen, central Norway. Based on habitat use, stomach contents, stable isotopes (δ<sup>13</sup>C, δ<sup>15</sup>N) and trophically transmitted parasites, ...

    • TRIM32, but not its muscular dystrophy-associated mutant, positively regulates and is targeted to autophagic degradation by p62/SQSTM1 

      Overå, Katrine Stange; Garcia-Garcia, Juncal; Bhujabal, Zambarlal; Jain, Ashish; Larsen, Kenneth Bowitz; Deretic, Vojo; Johansen, Terje; Lamark, Trond; Sjøttem, Eva (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-02)
      The tripartite motif (TRIM) proteins constitute a family of ubiquitin E3 ligases involved in a multitude of cellular processes, including protein homeostasis and autophagy. TRIM32 is characterized by six protein–protein interaction domains termed NHL, various point mutations in which are associated with limb-girdle-muscular dystrophy 2H (LGMD2H). Here, we show that TRIM32 is an autophagy substrate. ...
    • Tannmedisinsk turisme - konsekvenser for folkehelsen 

      Olsvik, Ørjan; Lund, Bodil Kristina (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-13)
      Globalisering av helsetjenester gir pasienter muligheter til å velge hvor de ønsker å bli behandlet.

      The sequencing of ancient DNA has enabled the reconstruction of speciation, migration and admixture events for extinct taxa. However, the irreversible post-mortem degradation of ancient DNA has so far limited its recovery—outside permafrost areas—to specimens that are not older than approximately 0.5 million years (Myr). By contrast, tandem mass spectrometry has enabled the sequencing of approximately ...

      Paterson, Rachel Anne; Nefjodova, Jelena; Salis, Romana; Knudsen, Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-09)
      Catchment-scale variation between lake habitats has the potential to simultaneously influence the trophic niche and parasite community of fish hosts. In this study, we investigated the trophic niche and parasite community of sympatric Arctic charr and brown trout populations from two inter-connected southern Norwegian lakes at different altitudes. Arctic charr and brown trout occupied profundal and ...
    • From clear lakes to murky waters – tracing the functional response of high-latitude lake communities to concurrent ‘greening’ and ‘browning’ 

      Hayden, B.; Harrod, C.; Thomas, S.M.; Eloranta, Antti; Myllykangas, J.‐P.; Siwertsson, Anna; Præbel, Kim; Knudsen, Rune; Amundsen, Per-Arne; Kahilainen, Kimmo Kalevi (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-21)
      Climate change and the intensification of land use practices are causing widespread eutrophication of subarctic lakes. The implications of this rapid change for lake ecosystem function remain poorly understood. To assess how freshwater communities respond to such profound changes in their habitat and resource availability, we conducted a space‐for‐time analysis of food‐web structure in 30 lakes ...

Utilizing suspension bead arrays, ≈1800 unique antibody pairs are first screened ...
    • Late Paleoproterozoic and Mesoproterozoic magmatism of the Nico Pérez Terrane (Uruguay): Tightening up correlations in southwestern Gondwana 

      Oriolo, Sebastián; Oyhantcabal, Pedro; Konopásek, Jiří; Basei, Miguel A.S.; Frei, Robert; Sláma, Jiří; Wemmer, Klaus; Siegesmund, Siegfried (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-04)
      New geochronological, isotopic and geochemical data were obtained from the late Paleoproterozoic and Mesoproterozoic magmatic units of the Nico Pérez Terrane (Uruguay). A U-Pb LA-ICP-MS zircon age of 1768 ± 11 Ma confirms the Statherian age for the Illescas rapakivi intrusion, being thus comparable with the age of the Campanero Unit felsic orthogneisses. Though both the Illescas and Campanero ...
    • På vei mot en kollegial tilnærming til undervisning – seminarundervisning og pedagogisk opplæring av stipendiater 

      Johansen, Greta Kristine; Beerepoot, Maarten (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-19)
      Seminarundervisning har en viktig rolle i realfagsundervisning i høyere utdanning. Læringsaktivitetene i seminarene samsvarer ofte godt med eksamensformen og dermed bidrar seminarundervisning betydelig til <i>constructive alignment</i> (Biggs, 1999) i et emne. Den viktige rollen seminarundervisning har står i sterk kontrast med den begrensede eller fraværende opplæring ...
    • Embeddings of weighted generalized Morrey Spaces into Lebesgue Spaces on fractal sets 

      Samko, Natasha Gabatsuyevna (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-19)
      We study embeddings of weighted local and consequently global generalized Morrey spaces defined on a quasi-metric measure set (X, d, μ) of general nature which may be unbounded, into Lebesgue spaces Ls(X), 1 ≤ s ≤ p < ∞. The main motivation for obtaining such an embedding is to have an embedding of non-separable Morrey space into a separable space. In the general setting of quasi-metric measure ...
    • PD+ based trajectory tracking of the underactuated quadrotor platform using dual quaternions 

      Johansen, Tor-Aleksander; Andersen, Tom Stian; Kristiansen, Raymond (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-29)
      We address the problem of state feedback trajectory tracking of the underactuated quadrotor platform in the dual quaternion framework through a PD+ tracking controller. The control law negates the need of generating a desired attitude trajectory as the translational error is mapped directly onto the rotational actuators through a virtual frame. More precisely, we show uniform practical asymptotic ...
    • The healthy body image (HBI) intervention: Effects of a school-based cluster-randomized controlled trial with 12-months follow-up 

      Borgen, Christine Sundgot; Friborg, Oddgeir; Kolle, Elin; Engen, Kethe Marie Elgesem; Sundgot-Borgen, Jorunn; Rosenvinge, Jan H; Pettersen, Gunn; Torstveit, Monica Klungland; Piran, Niva; Bratland-Sanda, Solfrid (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-28)
      We examined the effects of the Healthy Body Image (HBI) intervention on positive embodiment and health-related quality of life among Norwegian high school students. The intervention comprised three interactive workshops, with body image, media literacy, and lifestyle as main themes.

    • Zooarchaeological and stable isotope evidence of Sámi reindeer offerings 

      Salmi, Anna-Kaisa; Fjellström, Markus; Äikäs, Tiina; Spangen, Marte; Nunez, Milton; Lidén, Kerstin (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-19)
      This paper presents new osteometric and stable isotope evidence of Sámi reindeer offerings. Previous archaeological studies have shown that reindeer domestication and intensification of reindeer herding transformed Sámi indigenous religion. However, because of the methodological challenges in the identification of wild and domesticated reindeer in the archaeological record, the exact nature of the ...
    • Blending functions based on trigonometric and polynomial approximations of the Fabius function 

      Olofsen, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      Most simple blending functions are polynomials, while more advanced blending functions are, for example, rational or expo-rational fractions. The Fabius function has the required properties of a blending function, but is a nowhere analytic function and cannot be calculated exactly everywhere on the required domain. We present a new set of trigonometric and polynomial blending functions with the shape ...
    • Finite element method application of ERBS triangles 

      Kravetc, Tatiana (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11)
      In this paper we solve an eigenvalue problem on a circular membrane with fixed outer boundary by using a finite element method, where an element is represented as an expo-rational blending triangle. ERBS triangles combine properties of B-spline finite elements and standard polynomial triangular elements. The overlapping of local triangles allows us to provide a flexible handling of the surface while ...
