    • T-box transcription factor eomesodermin/Tbr2 in Atlantic cod (Gadus morhua L.): Molecular characterization, promoter structure and function analysis 

      Chi, Heng; Sørmo, Kristian Gillebo; Diao, Jing; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-11)
      Eomesodermin (Eomes) is a member of T-box transcription factor family and plays an important role in the regulation of a wide variety of developmental processes and immune response in animals. Here we report cloning and characterization of the full-length cDNA of Atlantic cod Eomes (GmEomes), which possesses a TBOX_3 domain similar to its counterpart in mammals. The regulated expression was observed ...
    • Taksonomiens betydning for nordnorsk næringsliv - en revolusjon eller evolusjon? 

      Angell, Louise Marie Solberg; Snekvik, Ragnhild (Master thesis; Mastergradsoppgave, 2023-05-31)
      For å finansiere overgangen til klimanøytralitet innen 2050, har EU utarbeidet en handlingsplan for bærekraftig finans. Tiltakene i handlingsplanen skal bidra til å styre kapital mot bærekraftige aktiviteter, øke transparens i finansmarkedene og redusere risikoen for grønnvasking. Det mest sentrale virkemidlet for å oppnå dette er opprettelsen av taksonomien for bærekraftige økonomiske aktiviteter. ...
    • Takvatnprosjektet - Forskning og kultivering av en overbefolka røyeberstand 

      Amundsen, Per-Arne; Smalås, Aslak; Knudsen, Rune; Kristoffersen, Roar; Siwertsson, Anna; Klemetsen, Anders (Research report; Forskningsrapport, 2015)
      Overbefolka fiskebestander er et stort problem i mange av våre innsjøer. Det typiske kjennetegnet er en stor tetthet av gammel, småvokst og mager fisk, gjerne med en høy infeksjon av parasitter. Hardt uttynningsfiske har vært foreslått som et mulig botemiddel, men selv om det har vært gjort mange forsøk på å komme problemet til livs, er det få som har lyktes. Denne rapporten ...

      Kidane, Dejene Gizaw (Doctoral thesis; Doktorgradsavhandling, 2022-05-02)
      <p>The dissertation includes four papers altogether. Three papers examine mechanisms for price transmission between markets. Among them, one deals with price transmission along the supply chain, and the other two deal with price transmission across spatially distinct markets. The fourth paper measures the effects of demand shifts on the market price equilibrium. <p>Paper 1 investigates price ...

Videre setter den fokus på forebyggende tiltak og hvilke felt man trenger ytterligere kunnskapsbygging på. Gjennomgående ...
    • Taxa-specific activity loss and mortality patterns in freshwater trematode cercariae under subarctic conditions 

      Born-Torrijos, Ana; Van Beest, Gabrielle S.; Vyhlídalová, Tereza; Knudsen, Rune; Kristoffersen, Roar; Amundsen, Per-Arne; Thieltges, David W.; Soldánová, Miroslava (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-11)
      Cercarial activity and survival are crucial traits for the transmission of trematodes. Temperature is particularly important, as faster depletion of limited cercarial energy reserves occurs at high temperatures. Seasonal climate conditions in high latitude regions may be challenging to complete trematode life cycle during the 6-month ice-free period, but temperature effects on the activity and ...
    • Taxonomic and functional approaches of trophic interactions between large herbivores and plant communities in a mountain ecosystem 

      Bison, Marjorie (Doctoral thesis; Doktorgradsavhandling, 2015-12-08)
      Given the key role of large herbivores on species and functional plant diversity, we aimed at better understanding the relationship between herbivory and plant communities mainly at a fine-scale, in order to reconcile objectives of population management and plant conservation. For this purpose, we used both taxonomic and functional approaches, and studied interactions at the inter- and intra-specific ...

    • TBT-induced imposex related to age and length in Buccinum undatum at two localities in Balsfjorden 

      Dahl-Hansen, Ida Elisabeth (Master thesis; Mastergradsoppgave, 2009-06-08)
      Background: The organotin compound tributyltin (TBT), used as an antifouling agent in ship hull paint, is known to cause imposex in several species of marine gastropods. Imposex is the imposition of male sexual characteristics on females, and can lead to female sterility. The common whelk, Buccinum undatum, is a common species in Norway and has received attention for its export potential. Because ...
    • Teambasert entreprenørskap. En casestudie av en etableringsprosess 

      Stokland, Siren Eilertsen (Master thesis; Mastergradsoppgave, 2007-05-15)
      Da det lenge har vært fokus på en entreprenør som alene går gjennom en etableringsprosess og starter opp en virksomhet, har det i de siste årene blitt mer fokus på entreprenørteam. Et entreprenørteam er flere personer som går sammen gjennom etableringsprosessen med å starte opp en virksomhet. Denne etableringsprosess starter opp med en ide, og om prosessen blir vellykket, ender opp med etablering ...
    • Teamekspansjon : en casestudie av en teamekspansjonsprosess i en nyetablert virksomhet 

      Holand, Stine (Master thesis; Mastergradsoppgave, 2007-11-29)
      Denne oppgaven tar for seg hvilke interne faktorer som kan ha betydning for en nyetablert virksomhets teamekspansjonsprosess. Nettopp hvordan et entreprenørteam tenderer til å utvikle seg over tid har fått liten oppmerksomhet i tidligere studier. En teamekspansjonsprosess vil nok være utfordrende for de fleste bedrifter, og da spesielt i nyetablerte virksomheter som har få tidligere erfaringer å ...
