    • On the temporal evolution of turbopause altitude, 1996-2021, 70 N, 19 E 

      Hall, Chris; Nozawa, S. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-04)
      Medium frequency radars with multiple receivers are able to track the movement of the interference pattern on the ground from echoes from irregularities in refractive index. In particular, refractive index in the mesosphere is determined by electron density – commonly known as the ionospheric D-region. Thus using this technique it is possible to determine winds in the height regime 70-90 km, ...

    • On Uniqueness of Submaximally Symmetric Vector Ordinary Differential Equations of C-Class 

      Kessy, Johnson Allen; The, Dennis (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-10)
      The fundamental invariants for vector ODEs of order ≥3 considered up to point transformations consist of generalized Wilczynski invariants and C-class invariants. An ODE of C-class is characterized by the vanishing of the former. For any fixed C-class invariant U , we give a local (point) classification for all submaximally symmetric ODEs of C-class with U≢0 and all remaining C-class invariants ...

    • The oncolytic peptide LTX-315 kills cancer cells through Bax/Bak-regulated mitochondrial membrane permeabilization 

      Zhou, Heng; Forveille, Sabrina; Sauvat, Allan; Sica, Valentina; Izzo, Valentina; Durand, Sylvère; Müller, Kevin; Liu, Peng; Zitvogel, Laurence; Rekdal, Øystein; Kepp, Oliver; Kroemer, Guido (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-10)
      LTX-315 has been developed as an amphipathic cationic peptide that kills cancer cells. Here, we investigated the putative involvement of mitochondria in the cytotoxic action of LTX-315. Subcellular fractionation of LTX-315-treated cells, followed by mass spectrometric quantification, revealed that the agent was enriched in mitochondria. LTX-315 caused an immediate arrest of mitochondrial ...

    • One-year protocol biopsies from ABO-incompatible renal allografts compared with a matched cohort of ABO-compatible allografts 

      Dörje, Christina; Mjøen, Geir; Strøm, Erik Heyerdahl; Holdaas, Hallvard; Jenssen, Trond Geir; Øyen, Ole; Akkøk, Cigdem Ahaein; Småstuen, Milada C; Midtvedt, Karsten; Reisæter, Anna Varberg (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-01-21)
      Abstract: Introduction: Early acute antibody-mediated rejection (ABMR) occurs more frequently in ABO-incompatible (ABOi) than in ABO-compatible (ABOc) kidney transplantation. This could lead to increased inflammation/scarring in the ABOi grafts. Protocol biopsy data in ABOi kidney recipients are scarce.<p> <p>Methods: A single-center retrospective matched cohort study was conducted. Eighty ...

    • Only benign encounters? The Sami, Wehrmacht, the secret police services and Lebensborn in the North Calotte at war, 1940–1944 

      Nyyssönen, Jukka Kalervo (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-17)
      This article sheds new light on previous perceptions of good relations between the occupant forces and the Sami minority in Finland and Norway between 1941 and 1944. The preconditions and varieties of relations and encounters are researched: those relating to the Gestapo and to Valpo, the Finnish state police, as well as to the Lebensborn. Sources utilized consist of archival material produced by ...

    • Ontogenetic changes in the body structure of the Arctic fish Leptoclinus maculatus 

      Pekkoeva, S.N.; Kondakova, E.A.; Falk-Petersen, Stig; Berge, Jørgen; Murzina, S.A (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-06)
      Histological studies of the ontogenetic changes in Arctic marine fishes are often fragmented and incomplete. Here we present a comprehensive histological ontogenetic analysis of the daubed shanny (<i>Leptoclinus maculatus</i>) from the Arctic, characterizing its development as it undergoes a series of changes in the organ and tissue organization, especially during the postlarvae transition from the ...

    • Ontogenetic niche shifts and resource partitioning in a subarctic piscivorous fish guild 

      Amundsen, Per-Arne; Bøhn, Thomas; Popova, Olga A.; Staldvik, Frode J.; Reshetnikov, Yuri S.; Kashulin, Nikolay A.; Lukin, Anatoly A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2003-05)
      The feeding ecology of three piscivorous fish species (perch (<i>Perca fluviatilis</i>), pike (<i>Esox lucius</i>) and burbot (<i>Lota lota</i>)), was studied in the subarctic Pasvik watercourse (69 ° N), northern Norway and Russia. All three species primarily occupied the benthic habitats in the watercourse. Perch and burbot exhibited distinct ontogenetic niche shifts in food resource use, perch ...

Sometimes all forms of use are permitted, other times only noncommercial use is permitted. Copyright laws were established to protect the interests of the creator. In traditional academic publication, copyrights are used to protect the interests of the ...

    • The Open Access publication fund at the University of Tromsø 

      Frantsvåg, Jan Erik (Journal article; Tidsskriftartikkel, 2011)
      Ved Universitetet i Tromsø er det nå etablert et publiseringsfond, som skal dekke forfatterbetaling i rene Open Access-tidsskrifter. I artikkelen gjøres det rede for utfomingen av regelverket for fondet, og hvilken tenking som ligger bak de ulike bestemmelsene.

    • Open Access publishing - a status from the University of Tromsø 

      Frantsvåg, Jan Erik (Journal article; Tidsskriftartikkel, 2011)
      Ved Universitetet i Tromsø har vi oppdaget at vi har tilgang til data som gjør at vi kan få et bilde av hvor mye som publiseres ved universitetet i forhold til den totale publiseringen, og vi er positivt overrasket. Vi har også gjort erfaringer med en avtale om gratis Open Choice hos Springer og hvilken betydning en slik avtale kan ha for volumet av OA-publisering.

    • Open Access the last ten years – how far have we come? 

      Frantsvåg, Jan Erik (Journal article; Tidsskriftartikkel, 2014)
      Ved ScieComs 10-årsjubileum kan det være interessant å kikke seg tilbake og forsøke å erindre seg hva som har skjedd på disse 10 årene. Mye er forandret, mye er på plass – men en god del gjenstår ennå. Det er bare å glede seg til å ta fatt!
