    • Protection of teleost fish against infectious diseases through oral administration of vaccines: Update 2021 

      Bøgwald, Jarl; Dalmo, Roy Ambli (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-10)
      Immersion and intraperitoneal injection are the two most common methods used for the vaccination of fish. Because both methods require that fish are handled and thereby stressed, oral administration of vaccines as feed supplements is desirable. In addition, in terms of revaccination (boosting) of adult fish held in net pens, oral administration of vaccines is probably the only feasible method to ...
    • Protein determination - Method matters 

      Mæhre, Hanne K.; Dalheim, Lars; Edvinsen, Guro K.; Jensen, Ida-Johanne; Elvevoll, Edel O.; Jensen, Ida-Johanne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-01)
      The reported protein content of foods depends on the analytical method used for determination, making a direct comparison between studies difficult. The aim of this study was to examine and compare protein analytical methods. Some of these methods require extraction preceding analysis. The efficacy of protein extraction differs depending on food matrices and thus extraction yield was determined. ...
    • Protein genes in repetitive sequence—antifreeze glycoproteins in Atlantic cod genome 

      Zhuang, Xuan; Yang, Chun; Fevolden, Svein-Erik; Cheng, Chi-Hing Christina (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Highly repetitive sequences are the bane of genome sequence assembly, and the short read lengths produced by current next generation sequencing technologies further exacerbates this obstacle. An adopted practice is to exclude repetitive sequences in genome data assembly, as the majority of repeats lack protein-coding genes. However, this could result in the exclusion of important genotypes in newly ...
    • Protein og kitin i grakse fra produksjon av Calanus® Oil 

      Udin, Therese Christina (Master thesis; Mastergradsoppgave, 2017-05-15)
      Letingen etter nye ressurser som er rik på flerumettede langkjedede omega-3 fettsyrer, har ført til utnyttelse av dyreplanktonet Calanus finmarchicus (raudåte). Det blir høstet inn ved tråling i overflaten under de mest lipidrike stadiene i vår- og sommermånedene. Den største andelen av lipidene er voksestere med et høyt innhold av omega-3 fettsyrer; stearidonsyre (18:4n-4), EPA (20:5n-3) og DHA ...

      Singer, David; Seppey, Victor William Christophe; Lentendu, Guillaume; Dunthorn, Micah; Bass, David; Belbahri, Lassaad; Blandenier, Quentin; Debroas, Didier; de Groot, G. Arjen; de Vargas, Colomban; Domaizon, Isabelle; Duckert, Clément; Izaguirre, Irina; Koenig, Isabelle; Mataloni, Gabriela; Schiaffino, M. Romina; Mitchell, Edward A.D.; Geisen, Stefan; Lara, Enrique (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-19)
      Protists dominate eukaryotic diversity and play key functional roles in all ecosystems, particularly by catalyzing carbon and nutrient cycling. To date, however, a comparative analysis of their taxonomic and functional diversity that compares the major ecosystems on Earth (soil, freshwater and marine systems) is missing. Here, we present a comparison of protist diversity based on standardized high ...

      Christensen, Chris Robin (Master thesis; Mastergradsoppgave, 2012-06-01)
      Hovedmålet med denne oppgaven har vært å fastslå sammensetningen av lipider og aminosyrer, i tillegg til vann og askeinnhold i blåskjell og kamskjell (Mytilus edulis og Pecten maximus). Evnen til å hemme angiotensin converterende enzym (ACE) ble også undersøkt. I tillegg ble det undersøkt hvilken effekt to ulike typer tilberedning hadde på de ulike faktorene. Resultatene viste en tydelig forskjell ...
    • Proximity dimensions and dynamics within an organisation: experiences from a change process 

      Jørgensen, Eva Jenny B.; Olafsen, Anja Hagen; Nilsen, Etty Ragnhild (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-16)
      Proximity between actors within an organisation can be relevant for interactive learning and innovation because it promotes collaboration and knowledge exchange. However, proximity has mainly been studied as a characteristic of the relationships between actors belonging to different organisations. In this paper, a case study of a faculty at a university is used to investigate proximity within this ...
    • Pseudocalanus (Copepoda: Calanoida) of the North Atlantic Ocean : species composition, environmental preferences and phylogeography 

      Aarbakke, Ole Nicolai S (Doctoral thesis; Doktorgradsavhandling, 2013-06-25)
      The seven species of the genus Pseudocalanus (Copepoda: Calanoida) are difficult to identify because of very small interspecific, and comparatively large intraspecific, divergence of morphologic and morphometric traits. Thus, despite the fact that Pseudocalanus spp. are among the most abundant metazoans in the world, our knowledge of them at the species level is limited. The main objective of this ...
    • Pseudocalanus in Svalbard waters : identification and distribution patterns of two sibling copepod species 

      Gudmundsdottir, Ragnhildur (Master thesis; Mastergradsoppgave, 2008-11-05)
      Marine copepods of the genus Pseudocalanus (Calanoida) are common in Svalbard waters as well as throughout the northern hemisphere. They contribute considerably to plankton biomass in addition to Calanus spp. and play an important role in the marine food web as a link between planktivores, such as fish larvae, and microalgae. Pseudocalanus consists of several sibling species, and two of them, ...
    • Psykologisk trygghet og samhold i distribuerte team 

      Engebø, Rune; Brustad, Janne (Master thesis; Mastergradsoppgave, 2023-05-23)
      Tidligere undersøkelser har vist at samhold og psykologisk trygghet er faktorer som påvirker hvor godt et team fungerer. Psykologisk trygghet handler om hvordan den enkelte opplever å være i en gruppe, mens samhold er limet som får en gruppe til å henge sammen. Fra teorien vet vi at det å ha fysisk kontakt med andre er viktig for å skape godt samhold. Samtidig viser funn at manglende opplevelse av ...
    • Psykologisk trygghet, arenaer og samhandling i akuttpsykiatrien 

      Tobiassen, Rakel M. (Master thesis; Mastergradsoppgave, 2023-05-30)
      Ved hjelp av kvalitativ metode har jeg studert hva som er forløperne til utviklingen av psykologisk trygghet for sykepleierne i akuttpsykiatrien. Slik kan jeg bidra med kunnskap om hva som sykepleierne selv oppgir er viktige faktorer for psykologisk trygghet. Dette kan bidra til et godt arbeidsmiljø og dermed økt stabilisering av sykepleierne som arbeidskraft og gir økt pasientsikkerhet i behandlingen. ...

      Hensikten med denne masteroppgaven er å utvikle kunnskap og bidra til økt forståelse av arbeidsgivers og midlertidig ansattes vurderinger og refleksjoner knyttet til psykologiske kontrakter og påvirkningskraften på deres arbeidsforhold. Det finnes omfattende forskning rundt bruken av fast ansatte, men den økte bruken av midlertidig ansatte krever ny forskning på denne yrkesgruppen. Psykologiske ...
    • Public Perceptions of Deep-Sea Environment: Evidence from Scotland and Norway 

      Ankamah-Yeboah, Isaac; Xuan, Bui Bich; Hynes, Stephen; Armstrong, Claire W. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-10)
      Knowledge of people's understanding of environmental problems is vital for the effective implementation of the ecosystem approach to marine management. This is especially relevant when conservation goals are aimed at ecosystems in the deep-sea that are remote to the consciousness of most people. This study explores public perceptions of the deep-sea environment among the Scottish and Norwegian public. ...
    • “Public perceptions of pink salmon in Norway and willingness to pay for the current eradication management program” 

      Aasmaa, Ekaterina (Master thesis; Mastergradsoppgave, 2022-05-13)
      Abstract Since 2017, Norway has experienced a large influx of Pacific pink salmon (Oncorhynchus gorbusha), and this species occurrence has created challenges for society, businesses, the environment, and policymakers. However, there is currently no consensus on whether pink salmon is a new resource or a pest in Norway. While some people perceive pink salmon as a food resource and a good recreational ...
    • Public vs. Private Governance in the Norwegian Aquaculture: Can the ASC Supplement or Supplant the Public Regulations? 

      Chowdhury, Fahmida (Master thesis; Mastergradsoppgave, 2020-11-15)
      It is predicted that by the year 2050, the world population will reach 9.8 billion (UN, 2017). The need for fish as a good source of nutrition is also increasing. Total global aquaculture production is now exceeding the global capture fisheries production by over 18.32 million tons (FAO,2019). This increasing demand for aquatic animals as human food, limited marine captured fisheries, and the ...
    • Publication practice in Taxonomy: Global inequalities and potential bias against negative results 

      Salvador, Rodrigo Brincalepe; Cavallari, Daniel caracanhas; Rands, Douglas; Tomotani, Barbara mizumo (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-01)
      There is broad recognition by practicing taxonomists that the field is going through a crisis, which has been dubbed the “taxonomic impediment”. There are many aspects involved in said crisis, but publication practices in taxonomy are often neglected or relegated to the backseat. We provide an initial foray into this topic via a worldwide survey with taxonomists, spanning all botanical and ...
    • Pulling mechanisms and pushing strategies: How to improve Ecosystem Advice Fisheries Management advice within the European Union’s Common Fisheries Policy 

      Ramirez-Monsalve, Paulina; Nielsen, Kåre Nolde; Ballesteros, Marta; Kirkfeldt, Trine; Dickey-Collas, Mark; Delaney, Alyne; Hegland, Troels Jacob; Raakjær, Jesper; Degnbol, Poul (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-17)
      While European policies have progressed towards an Ecosystem Approach to Fisheries Management (EAFM), limited attention has been paid to the implications for its advisory system. This paper analyses the advisory landscape in the European Union (EU) by addressing two questions: to what extent can the needed advice be provided? how prepared is the management system to integrate ecosystem advice? We ...
    • Pushed or pulled? Understanding fishery exit in a welfare society context 

      Johnsen, Jahn Petter; Vik, Jostein (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      For a long time the number of fishers in Norway has declined. Is the decline the result of an increasingly difficult situation for Norwegian fishers or can other factors have had an impact? Or in other words: are fishers pushed out or pulled out of the fisheries? Our analyses are based on a survey among retired fishers and suggest several reasons for exit: in addition to structural push and pull ...
    • Puslespill eller svarteper. Er psykologisk trygghet en viktig spillebrikke i tverrfaglig samarbeid 

      Hevrøy, Linda; Slettevold, Lillian (Master thesis; Mastergradsoppgave, 2023-05-31)
      Denne studien er en case-studie av Familiens hus i en kommune. Som kommunalt ansatte i oppvekstfeltet opplever vi at det er vanskelig å få til et godt tverrfaglig samarbeid i komplekse saker med mange hjelpere. Når tverrfaglig samarbeid ikke virker kan det få alvorlige konsekvenser for barn, unge og familier. Gjennom flere tilsyn og rapporter er det avdekket svikt på dette området (NOU 2017: 12). ...
    • Qualitative and Quantitative Comparison of Liquid–Liquid Phase Extraction Using Ethyl Acetate and Liquid–Solid Phase Extraction Using Poly-Benzyl-Resin for Natural Products 

      Schneider, Yannik Karl-Heinz; Andersen, Jeanette Hammer; Hansen, Espen; Jørgensen, Solveig M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-01)
      A key step in the process of isolating microbial natural products is the preparation of an extract from a culture. This step determines which molecules will be available for detection in the subsequent chemical and biological analysis of a biodiscovery pipeline. In the present study we wanted to document potential differences in performance between liquid–liquid extraction using ethyl acetate ...
