    • 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 ...

      Furnesvik, Lisa; Erkinharju, Toni; Hansen, Miroslava (Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
      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 ...

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 ...

      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 ...

    • Barriers and obstacles to foreign direct investment (FDI) into Russia 

      Shevtsova, Julia (Master thesis; Mastergradsoppgave, 2006-06-08)
      The transition from socialism to capitalism in Russia is both a political and an economic process. An important aspect of the latter is the possibility of integration into the world economy (through trade and capital flows) is a crucial and related element of the former. Foreign direct investment (FDI) is a particularly important element of the transition process itself and economic integration, ...
    • Bat echolocation plasticity in allopatry: a call for caution in acoustic identification of Pipistrellus sp. 

      Montauban, Cecilia; Mas, Maria; Tuneu-Corral, Carme; Wangensteen, Owen S.; Budinski, Ivana; Martí-Carreras, Joan; Flaquer, Carles; Puig-Montserrat, Xavier; López-Baucells, Adrià (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-23)
      Animals modify their behaviours and interactions in response to changing environments. In bats, environmental adaptations are reflected in echolocation signalling that is used for navigation, foraging and communication. However, the extent and drivers of echolocation plasticity are not fully understood, hindering our identification of bat species with ultrasonic detectors, particularly for cryptic ...
    • Batch Experiments Demonstrating a Two-Stage Bacterial Process Coupling Methanotrophic and Heterotrophic Bacteria for 1-Alkene Production From Methane 

      Khanongnuch, Ramita; Mangayil, Rahul; Santala, Ville; Hestnes, Anne Grethe; Svenning, Mette Marianne; Rissanen, Antti J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-19)
      Methane (CH<sub>4</sub>) is a sustainable carbon feedstock for value-added chemical production in aerobic CH<sub>4</sub>-oxidizing bacteria (methanotrophs). Under substrate-limited (e.g., oxygen and nitrogen) conditions, CH<sub>4</sub> oxidation results in the production of various short-chain organic acids and platform chemicals. These CH<sub>4</sub>-derived products could be broadened by ...
    • Bats as natural samplers: First record of the invasive pest rice water weevil Lissorhoptrus oryzophilus in the Iberian Peninsula 

      Montauban, Cecilia; Mas, Maria; Wangensteen, Owen S.; Sarto i Monteys, Víctor; Gisbert Fornós, David; Ferré Mola, Xavi; López-Baucells, Adrià (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-19)
      We face an increasing global food security challenge as the human population continues to grow across the globe. As agricultural production rises to keep up with food demand, so too does the expansion of crop detrimental pest species. Early detection can be crucial to control their damage and relies on the use of accurate and dependable techniques. We report the first record of rice water weevil ...
    • Bats as potential suppressors of multiple agricultural pests: A case study from Madagascar 

      Kemp, James; López-Baucells, Adrià; Rocha, Ricardo; Wangensteen Fuentes, Owen Simon; Andriatafika, Zo; Nair, Abhilash; Cabeza, Mar (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-01)
      The conversion of natural habitats to agriculture is one of the main drivers of biotic change. Madagascar is no exception and land-use change, mostly driven by slash-and-burn agriculture, is impacting the island's exceptional biodiversity. Although most species are negatively affected by agricultural expansion, some, such as synanthropic bats, are capable of exploring newly available resources and ...
