    • Hvordan kan styret i et aksjeselskap oppfylle sitt ansvar ved å bruke revisors arbeid? En anbefaling basert på en analyse av rettspraksis i erstatningssaker mot styret og revisor 

      Ingebrigtsen, Miriam (Master thesis; Mastergradsoppgave, 2019-05-28)
      I de siste årene har det vært flere erstatningssaker som omhandler styrets og revisors ansvar i aksjeselskaper. Erstatningssakene har oppstått på grunn av økonomiske tap, hvilket betyr at styret eller revisor kanskje ikke har oppfylt sitt ansvar. Styret er et selskapsorgan som etter aksjeloven er tillagt et stort ansvarsområde. Siden styret er tillagt et stort ansvarsområde, kan det være vanskelig ...
    • En helhetlig forskningsprosess. En kvantitativ studie om læring av fagkunnskap i organisk kjemi gjennom praktisk arbeid 

      Hansen, Janita Fosslund (Master thesis; Mastergradsoppgave, 2019-05-30)
      Praktisk arbeid har en uvurderlig og uerstattelig plass i naturfagundervisningen. Både læreplanen i kjemi og fagfornyelsen i naturfag som inntrer i 2020 beskriver fagenes praktiske aspekt som svært sentralt. Dessverre rapporter forskning fra flere hold at praktisk arbeid som undervisningsmetode ikke lever opp til sitt fulle potensial slik det blir praktisert i dag. Især viser det seg å være vanskelig ...

    • Structure activity investigations of XTH inhibitors 

      Kosonen, Juho Aleksi (Master thesis; Mastergradsoppgave, 2019-05-15)
      XTHs (xylogclucan endotransglucosylase/hydrolases) are a group of plant enzymes that regulate xyloglucan crosslinking in cell walls and play an essential role in regulation of plant growth. It is thought that XTHs play an integral role in the way the parasitic vine plant Cuscuta is able to penetrate host plant cell walls. Parasitic higher plants are a formidable threat to agricultural production ...
    • Development of a novel method for the analysis of acyl carnitine profile using liquid chromatography mass spectrometry 

      Spickova, Hana (Master thesis; Mastergradsoppgave, 2019-05-15)
      Carnitine is a low-molecular-weight compound that has an obligate role in the mitochondrial oxidation of long-chain fatty acids (acyl groups) and energy production. Therefore, acylcarnitines are essential diagnostic markers for complex diseases, fatty acid metabolism disorders, and disorders related to amino acids metabolism. Biochemical screening of the acylcarnitine profile is performed in clinical ...
    • Synthesis of XTH inhibitors 

      Pettersen, Martin (Master thesis; Mastergradsoppgave, 2019-05-15)
      XTH er en gruppe enzymer som ble oppdaget tidlig på 90 tallet og muligens er involvert i Cuscuta infeksjonen av tomater. En nylig studie gjort ved arktisk og marin biologi UIT viser at Brilliant Blue R250 fungerer som en god inhibitor mot disse enzymene. I dette prosjektet ble det fokusert på å syntetisere strukturelt like molekyler for å potensielt øke vannløseligheten og inhibitoraktiviteten. ...

    • Heritage language acquisition: What it reveals and why it is important for formal linguistic theories 

      Lohndal, Terje; Rothman, Jason; Kupisch, Tanja; Westergaard, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-30)
      This paper discusses the interplay between acquisition and theory construction. It endeavors to show how a more direct and crucially bi‐directional relationship between formal linguistic theory and the study of heritage language bilingualism can provide mutual benefit. It will be argued that data from acquisition—not exclusively but indeed especially from heritage language bilingualism—provide windows ...
