      Aaserud, Morten; Kristiansen, Ivar Sønbø; Neilson, Aileen Rae; Norum, Jan; Sørbye, Halfdan; Aas, Eline; Gjertsen, Marianne Klemp (Research report; Forskningsrapport, 2007)
      Vi har gjennomført en modellbasert analyse av kostnadseffektiviteten av bevacizumab som førstelinjebehandling av metastatisk kolorektalcancer (tykk- og endetarmskreft) i Norge. Vi har undersøkt effekten av å legge bevacizumab til standard kjemoterapi. Beregningene er forbundet med betydelig usikkerhet, og resultatene bør derfor tolkes med forsiktighet.
    • Chrysochromulina leadbeateri - Understanding the Presumed Causal Agent Behind the Harmful Algal Bloom of 2019 

      Grann-Meyer, Erlend (Master thesis; Mastergradsoppgave, 2020-08-18)
      In the Spring of 2019, a harmful algal bloom (HAB) of Chrysochromulina leadbeateri decimated 14 500 tonnes of caged salmon in the Northern Norwegian coastal regions. C. leadbeateri is a natural part of the marine microbiome along the Norwegian coast, and similar events have happened in the past. To heighten our understanding of how these HABs develops, and capacity of the causal agent as a harmful ...
    • Predicting the Auroral Oval Boundaries by Means of Polar Operational Environmental Satellite Particle Precipitation Data 

      Breedveld, Mikkel Jelle (Master thesis; Mastergradsoppgave, 2020-06-29)
      New empirical Kp-based models for the equatorward and poleward boundaries of the auroral oval in the Northern and Southern Hemispheres were developed, with the purpose of reviewing the auroral ovals predicted by well-established Feldstein auroral oval model. The new models were derived from particle and energy flux measurements from six low-altitude (800-900 km) POES/MetOp satellites. The equatorward ...
    • Spenningsfeltet mellom ytringsfriheten og hatefulle ytringer i sosiale medier 

      Nielsen, Frida Eilertsen (Master thesis; Mastergradsoppgave, 2020-06-15)
      Aldri før har bruken av sosiale medier vært større. Det interessante i denne sammenheng knytter seg til diskriminerende og hatefulle ytringer på sosiale plattformer. Spenningsforholdet mellom Grl. § 100 og strl. § 185 vil stå sentralt i denne fremstillingen. Oppgaven vil søke å besvare to problemstillinger hvorav den første er: Hvor går grensen for når en diskriminerende og hatefull ytring på ...
    • Kjøpsintensjon av sjømat. Påvirkningskraften fra reklamer og influensere i sosiale medier 

      Rydningen, Emilie (Master thesis; Mastergradsoppgave, 2020-06-09)
      Sjømatkonsumet blant unge voksne i Norge har sunket de siste årene. I denne oppgaven har jeg sett på hvordan markedsføring og reklamer via influensere på sosiale medier kan snu dette og påvirke kjøpsintensjon. Faktorene som ble inkludert i denne studien var faktorer ved budskapet og faktorer ved avsender, i tillegg til involvering og aktivitet. Tillit til reklameinnlegg er også en sentral ...
    • A catch comparison study on different codend designs to evaluate bycatch reduction in the North-East Atlantic deep-water shrimp (Pandalus borealis) fishery 

      Pettersen, Hermann Magnus Hagen (Master thesis; Mastergradsoppgave, 2020-05-15)
      Currently, there is a growing interest in the North-East Atlantic deep-water shrimp (Pandalus borealis) fishery with more actors expected to take part in the coming years. As the species and size of targeted shrimp varies globally, selectivity in this fishery is based on a grid system in front of a small mesh sized codend to avoid bycatch while simultaneously maintaining shrimp catches. However, ...
    • The Role of Silicate in the Parasitism of Pleurosigma sp. Diatoms by the Thraustochytrid Phycophthorum isakeiti 

      Powers, Daniel Jerome Finley (Master thesis; Mastergradsoppgave, 2020-05-15)
      The recently described thraustochytrid diatom parasite Phycophthorum isakeiti has been isolated from the marine system of northern Norway (Hassett, 2020). Protist P. isakeiti’s ecological role, biodiscovery potential, and interactions with a possible diatom host, Pleurosigma sp. remain largely unexplored. Here I present culturing experiments to test whether P. isakeiti is an obligate parasite. To ...
    • Keratocyttlignende celler fra hornhinne og hud hos atlantisk laks (Salmo salar L.). Mikro- og nanoplast, mitokondrieutveksling, fusjonering og celletunneler 

      Kjølstad, Eskil Mossige; Svartaas, Ole Kristian Helstad (Master thesis; Mastergradsoppgave, 2020-05-15)
      Huden og hornhinnen utgjør fiskens forsvarsbarrierer mot ytre påkjenninger. Begge har mobile celler kalt keratocytter. Dette er en av de mest bevegelige cellene som er kjent. Cellene gjenoppretter raskt barrieren hvis vevet skades ved å vandre ut fra sårkantene mot midten av såret. Sårhelingen effektiviseres ved at cellene bedriver fagocyttisk aktivitet av fremmedlegemer. Siden cellene er meget ...
    • Markedsadgang for atlantisk laks fra Chile til USA 

      Berntsen, Joakim (Master thesis; Mastergradsoppgave, 2020-05-14)
      Norge eksporterte laks for 72,5 milliarder kroner i 2019 og i verdiskapning er laks den største og viktigste arten for Norge innen sjømat. Til sammenligning eksporterte Chile atlantisk laks for 32,8 milliard i 2019. En stor del av den norske eksporten går til EU-markedene, mens Chiles viktigste eksportmarked er USA. Formålet med denne oppgaven er å se om Chile har bedre markedsadgang inn til USA ...

      Margari, Vasiliki; Skinner, Luke C.; Menviel, Laurie; Capron, Emilie; Rhodes, Rachael H; Mleneck-Vautravers, Maryline J.; Ezat, Mohamed; Martrat, Belen; Grimalt, Joan O.; Hodell, David A; Tzedakis, Polychronis (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-13)
      The abrupt nature of warming events recorded in Greenland ice-cores during the last glacial has generated much debate over their underlying mechanisms. Here, we present joint marine and terrestrial analyses from the Portuguese Margin, showing a succession of cold stadials and warm interstadials over the interval 35–57 ka. Heinrich stadials 4 and 5 contain considerable structure, with a short ...
    • EUs markedsadgang for fisk og sjømat til Japan og Sør-Korea - En komparativ analyse av handelsvilkårene til EU og Norge 

      Andreassen, Kristoffer André (Master thesis; Mastergradsoppgave, 2020-05-14)
      Den Europeiske Union (EU) er verdens største marked med en felles ytre tollmur, målt i verdi. EU er også Norges aller viktigste handelspartner for sjømateksport, og står for importen av om lag 2/3 av all norsk sjømateksport. Dette gjør at Norge står i en utsatt posisjon om EU skulle bortfalle som marked, og det er derfor interessant å skulle se på hvordan EUs markedsadgang er for sjømat i eksterne ...
    • Detecting EV Charging From Hourly Smart Meter Data 

      Barkost, Per Harald (Master thesis; Mastergradsoppgave, 2020-05-15)
      Detecting electrical vehicle (EV) charging from smart meter data (EV detection) is a highly relevant problem for the distribution system operators (DSOs), especially with the expected growth of EVs worldwide. There are several reasons why DSOs may want to detect EV charging. In the present day, the main motivation is to reduce the total load on the grid in high demand periods. This can be achieved ...
    • Reservoir computing approaches for representation and classification of multivariate time series 

      Bianchi, Filippo Maria; Scardapane, Simone; Løkse, Sigurd; Jenssen, Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-29)
      Classification of multivariate time series (MTS) has been tackled with a large variety of methodologies and applied to a wide range of scenarios. Reservoir computing (RC) provides efficient tools to generate a vectorial, fixed-size representation of the MTS that can be further processed by standard classifiers. Despite their unrivaled training speed, MTS classifiers based on a standard RC ...

      <i>Background</i> - The use of potentially inappropriate medications (PIMs) are associated with negative health effects for older adults. The purpose of this study was to apply national register data to investigate the impact of hospitalisation to geriatric wards in Norway on the use of medications and PIMs, and to compare two explicit PIM identification tools.<p><p> <i>Methods</i> - We included ...
    • Trålernes leveringsplikt, en legitim ordning? En analyse av debatten omkring pliktsystemet og mulige konsekvenser ved bortfall av leveringsforpliktelsene. 

      Daouli, Maria (Master thesis; Mastergradsoppgave, 2018-11-15)
      Langs kysten av Nord-Norge, på stortinget, og i media går debatten varm når enkelte tråleiere, ikke lever opp til samfunnets forventninger som råstoffleverandør, og samfunnsbærende næring i fiskeriavhengige kommuner. Mer spesifikt handler debatten om politiske virkemidler, heretter kalt pliktsystemet, som har med hensikt å trygge bosetting og sysselsetting i tilgodesette kommuner. Gjennom pliktsystemet ...
    • REE+Y uptake and diagenesis in Recent sedimentary apatites 

      Lumiste, Kaarel; Mänd, Kaarel; Bailey, Juke; Paiste, Päärn; Lang, Liisa; Lepland, Aivo; Kirsimäe, Kalle (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-30)
      Rare Earth Elements and Yttrium (REE+Y) distribution in authigenic phases are frequently used as proxies for reconstructing past seawater conditions. Sedimentary apatite precipitates near the sediment-water interface and is therefore capable of recording the REE+Y composition of the overlying water column. While the overprinting of primary REE+Y signal during late stage diagenesis is a widely known ...
    • Palaeoproterozoic oxygenated oceans following the Lomagundi–Jatuli Event 

      Mänd, Kaarel; Lalonde, Stefan V.; Robbins, Leslie J.; Thoby, Marie; Paiste, Kärt; Kreitsmann, Timmu; Paiste, Päärn; Reinhard, Christopher T.; Romashkin, Alexandr E.; Planavsky, Noah J.; Kirsimäe, Kalle; Lepland, Aivo; Konhauser, Kurt O. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-16)
      The approximately 2,220–2,060 million years old Lomagundi–Jatuli Event was the longest positive carbon isotope excursion in Earth history and is traditionally interpreted to reflect an increased organic carbon burial and a transient rise in atmospheric O<sub>2</sub>. However, it is widely held that O<sub>2</sub> levels collapsed for more than a billion years after this. Here we show that black shales ...
    • Spatial and temporal distributions in the Norwegian cod fishery 

      Ashrafi, Tannaz Alizadeh; Eide, Arne; Hermansen, Øystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-25)
      Fisheries are characterized by variations in space and time. This study investigates the characteristics of seasonality in cod trawl fisheries in two distinct areas: the coast along the northern Norway and the high sea area of the Barents Sea. Catch per unit effort (CPUE) is used to proxy variation in stock abundance. A CPUE function has been estimated in the frequency‐domain framework, to detect ...
