    • B-1 plasma cells require non-cognate CD4 T cell help to generate a unique repertoire of natural IgM 

      Jensen, Ingvill (Journal article; Tidsskriftartikkel; Peer reviewed, 2023)
      Evolutionarily conserved, “natural” (n)IgM is broadly reactive to both self and foreign antigens. Its selective deficiency leads to increases in autoimmune diseases and infections. In mice, nIgM is secreted independent of microbial exposure to bone marrow (BM) and spleen B-1 cell–derived plasma cells (B-1PC), generating the majority of nIgM, or by B-1 cells that remain non-terminally differentiated ...

    • Bacterial flagellin : a novel adjuvant for vaccine strategies 

      Hynes, Natasha (Doctoral thesis; Doktorgradsavhandling, 2011-10-18)
      Flagellin is the principal structural protein in the locomotive organ flagellum present on flagellated bacteria, and is known to be an important evolutionarily conserved PAMP. Flagellin has been shown to bind to the PRR TLR5 which induces innate immune system responses and signaling pathways. In mammals, much focus has been placed on this protein in vaccine studies for its possible function as an ...

    • The Bacterial Microbiome in the Small Intestine of Hooded Seals (Cystophora cristata) 

      Acquarone, Mario; Salgado-Flores, Alejandro; Sundset, Monica Alterskjær (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-27)
      Arctic hooded seals (Cystophora cristata) are monogastric carnivores that go through extreme fasting and re-feeding in early life. They are born isolated on sea ice; suckle high-fat milk for four days and may then fast for up to one month before they start hunting and feeding on small prey (fish and crustaceans). Previous studies of the gut microbiota in pinnipeds have focused on the large intestine, ...

    • Bacterial Natural Product Drug Discovery for New Antibiotics: Strategies for Tackling the Problem of Antibiotic Resistance by Efficient Bioprospecting 

      Schneider, Yannik Karl-Heinz (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-10)
      The problem of antibiotic resistance has become a challenge for our public health and society; it has allowed infectious diseases to re-emerge as a risk to human health. New antibiotics that are introduced to the market face the rise of resistant pathogens after a certain period of use. The relatively fast development of resistance against some antibiotics seems to be closely linked to their microbial ...

    • Bacterial response to permafrost derived organic matter input in an Arctic fjord 

      Müller, Oliver; Seuthe, Lena; Bratbak, Gunnar; Paulsen, Maria Lund (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-06)
      The warming of the Arctic causes increased riverine discharge, coastal erosion, and the thawing of permafrost. Together, this is leading to an increased wash out of terrestrial dissolved organic matter (tDOM) into the coastal Arctic ecosystems. This tDOM may be anticipated to affect both carbon and nutrient flow in the microbial food web and microbial community composition, but there are few ...

      Veterinærinstituttet mottok i januar i år en innsendelse fra et settefiskanlegg for rognkjeks. Rognkjeksen var 10-13 gram og uvaksinert. Settefiskanlegget er et gjennomstrømningsanlegg med sjøvann. Det var mistanke om gjelleproblematikk da det ble rapportert om døde individer med utspilte gjellelokk og bleke gjeller. Ved Veterinærinstituttet ble det gjennomført histopatologiske og immunhistokjemiske ...

    • Bakterievekst under naturtørking av tørrfisk: Sammenligning av normal- og mucosovev 

      Bjørkevoll, Ingebrigt; Landfald, Bjarne; Ernstsen, Marita Holm; Joensen, Sjurdur; Tidemann, Even (Research report; Forskningsrapport, 2008-04)
      Mikroorganismer antas å påvirke utviklingen av lukt og smak i tørrfisk, men det er lite er kjent om hvilke organismer som dominerer under tørkeprosessen. Samtidig er mikrobielle forhold er også antatt å være essensielle for utviklingen av mucoso, som er en kvalitetsfeil i tørrfisk der deler av fiskemuskelen blir oppløst og slimaktig. Slike partier må skjæres bort under bløtingsprosessen. Denne ...

      Understanding the tradeoff between tourism development and environmental conservation is essential for the sustainable management of ecotourism. Accordingly, we conducted a choice experiment (CE) using valuation workshops to estimate the preferences of foreign tourists for ecotourism development and biodiversity conservation in Rekawa coastal wetland in Southern Sri Lanka. Transforming preferences ...

    • Balansert målstyring - En analyse av konseptets utvikling i Sparebank 1 Nord-Norge 

      Alskog Olsen, Anette (Master thesis; Mastergradsoppgave, 2013-05-31)
      Bedrifter står i dag overfor høyst usikre omgivelser og hurtigendrede markeder der ledere må legge strategier for å forbedre organisatorisk ytelse (Gupta, 2012) og debatten rundt de eksisterende systemer har i seg selv vært en driver i utviklingen av nye (Kald og Nilsson, 2000). Temaet for denne oppgaven er Balansert Målstyring (BM). BM har vært et kjent konsept siden Kaplan og Norton introduserte ...

    • Ballasting by cryogenic gypsum enhances carbon export in a Phaeocystis under-ice bloom 

      Wollenburg, JE; Katlein, C; Nehrke, Gernot; Nöthig, E.-M; Matthiessen, J; Wolf-Gladrow, Dieter A.; Nikolopoulos, A.; Gazquez-Sanchez, F; Rossmann, L; Assmy, Philipp; Babin, Marcel; Bruyant, F; Beaulieu, Michaël; Dybwad, Christine; Peeken, Ilka (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-16)
      Mineral ballasting enhances carbon export from the surface to the deep ocean; however, little is known about the role of this process in the ice-covered Arctic Ocean. Here, we propose gypsum ballasting as a new mechanism that likely facilitated enhanced vertical carbon export from an under-ice phytoplankton bloom dominated by the haptophyte Phaeocystis. In the spring 2015 abundant gypsum crystals ...

    • Bare en brikke i et statlig puslespill? Sammenslåing av fylkesmannsembeter - de ansattes stemme. 

      Eriksen, Kristin Fjellheim (Master thesis; Mastergradsoppgave, 2018-05-31)
      Den siste tiden har det skjedd store endringer i fylkesstrukturen i Norge, der flere fylker har blitt slått sammen, og flere skal slås sammen på sikt. Temaet for oppgaven vil derfor være ivaretakelse av de ansatte gjennom en sammenslåingsprosess av fylkesmannsembeter, med utgangspunkt i Nord- og Sør-Trøndelag. I studien ble det tatt utgangspunkt i følgende problemstilling: ”Hvordan ble de ansatte ...

    • Bargaining with asymmetric externalities 

      Pereau, Jean Christophe; Clark, Derek J. (Working paper; Arbeidsnotat, 2007-02)
      We consider sequential bargaining between three firms that are all essential in creating a surplus. One of the firms is dominant in the sense that it ultimately decides whether the surplus will be created. The other firms have an incentive to get a large share of the pie for themselves, but leaving enough for the dominant firm that it finds it profitable to create the surplus. Hence, the smaller ...

    • Barns holdning til sjømat. Hvilken holdning har barn til sjømat, og hvordan innvirker eksponering og sosial påvirkning deres holdning? 

      Alm, Siril (Master thesis; Mastergradsoppgave, 2009-05-15)
      Bakgrunnen for denne studien er regjeringens anbefalinger om å øke barn og unges konsum av sjømat. Ut fra dette ble Fiskesprell igangsatt i norske barnehager og ungdomsskoler. Dette var en frivillig ordning som hadde til hensikt å fremme sjømat som en naturlig del i barns kosthold og tilby barna mer sjømat. Med utgangspunkt i forskning som viser at barn danner sine holdninger til mat ut fra både ...
