    • Subsidies—Help or Hurt? A Study from Vietnamese Fisheries 

      Pham, Thi Thanh Thuy; Flaaten, Ola; Nguyen, Trong Luong; Vu, Ke Nghiep (Journal article; Tidsskriftartikkel, 2021)
      Subsidies are part of the set of management tools that governments apply to modernize their fishing fleets and enable them to engage in offshore and international fisheries. Research has shown that subsidies often lead to overcapacity and overfishing, resulting in the depletion of fish stocks. A few studies, however, have found some positive effects for particular subsidies. In this paper, we ...
    • The Pseudoalteromonas multipartite genome: distribution and expression of pangene categories, and a hypothesis for the origin and evolution of the chromid 

      Sonnenberg, Cecilie Bækkedal; Haugen, Peik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-21)
      Bacterial genomes typically consist of one large chromosome, but can also include secondary replicons. These so-called multipartite genomes are scattered on the bacterial tree of life with the majority of cases belonging to Proteobacteria. Within the class gamma-proteobacteria, multipartite genomes are restricted to the two families <i>Vibrionaceae</i> and <i>Pseudoalteromonadaceae</i>. Whereas the ...

On the Kenai Peninsula, records of GLOFs from Snow Glacier date as far back as 1949, affecting downstream communities and infrastructure along the Kenai and Snow river ...
    • Long-term dynamics of metazoan parasites in an age- and size-structured host population 

      Henriksen, Eirik Haugstvedt (Doctoral thesis; Doktorgradsavhandling, 2021-10-29)
      <p>Parasites negatively affect hosts and may constitute serious management problems. At the same time, parasites are integral components of ecosystems and represent a substantial part of the biodiversity on earth. Understanding the ecological factors that influence the abundance and distribution of parasite populations is therefore important from a management perspective, but also to understand the ...

      When analysing a large cohort of Staphylococcus haemolyticus , using whole-genome sequencing, five human isolates (four from the skin and one from a blood culture) with aberrant phenotypic and genotypic traits were identified. They were phenotypically similar with yellow colonies, nearly identical 16S rRNA gene sequences and initially speciated as S. haemolyticus based on 16S rRNA gene sequence and ...
    • Hvordan kommuniserer lærere med elevene i teknologiprosjekter? 

      Lysne, Dag Atle; Esjeholm, Bjørn Tore (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-14)
      Inquiry-based methods have been seen as important for developing science in school. There are good reasons why the work of designing various technological devices in technology should also be part of inquiry-based methods. If so, it requires that the teachers have an exploratory approach in communicat-ing with students. In this paper, we analyze the communication between teachers and students in six ...

    • Isolation, structure elucidation and bioactivity profiling of lyso-ornithine lipids from the marine bacterium Lacinutrix sp. 

      Jawad, Jawad (Master thesis; Mastergradsoppgave, 2021-05-11)
      From previous work, it was identified two analytes of interest, produced by Lacinutrix sp. The two analytes are iso-branched lyso-ornithine lipids with only one CH2 group differing between the two compounds, in the hydrocarbon chain (lysoC15:0 and C16:0). The bacterium was isolated from the marine sponge Halicondria sp. that was collected beside Bjørnøya, on a research cruise in 2009. The analytes ...
    • Roll motion on small traditional Norwegian fishing vessels 

      Kristiansen, Gøran (Master thesis; Mastergradsoppgave, 2021-08-09)
      Roll motion is one of the six degrees of freedom and is the most difficult to predict, as roll motion is extremely sensitive to the viscous effect and induced flow separation. The smaller fishing vessel fleet commonly operates in almost all weather conditions, and sometimes in remote areas with cold arctic water where rescue can be far away and difficult. The safety of fishers depends on the vessel's ...

      Butt, Julia; Jenab, Mazda; Werner, Jill; Fedirko, Veronika; Weiderpass, Elisabete; Dahm, Christina C.; Tjønneland, Anne; Olsen, Anja; Boutron-Ruault, Marie-Christine; Rothwell, Joseph A.; Severi, Gianluca; Kaaks, Rudolf; Turzanski-Fortner, Renée; Aleksandrova, Krasimira; Schulze, Matthias B.; Palli, Domenico; Pala, Valeria; Panico, Salvatore; Tumino, Rosaria; Sacerdote, Carlotta; Bueno-De-Mesquita, Bas; van Gils, Carla H.; Gram, Inger Torhild; Lukic, Marko; Sala, Núria; Sánchez Pérez, Maria José; Ardanaz, Eva; Chirlaque, Maria-Dolores; Palmquist, Richard; Löwenmark, Thyra; Travis, Ruth C.; Heath, Alicia K.; Cross, Amanda J.; Freisling, Heinz; Zouiouich, Semi; Aglago, Elom; Waterboer, Tim; Hughes, David J. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-20)
      Experimental evidence has implicated genotoxic <i>Escherichia coli (E. coli)</i> and enterotoxigenic <i>Bacteroides fragilis</i> (ETBF) in the development of colorectal cancer (CRC). However, evidence from epidemiological studies is sparse. We therefore assessed the association of serological markers of <i>E. coli</i> and ETBF exposure with odds of developing CRC in the European Prospective Investigation ...

    • Semi-supervised target classification in multi-frequency echosounder data 

      Choi, Changkyu; Kampffmeyer, Michael; Handegard, Nils Olav; Salberg, Arnt Børre; Brautaset, Olav; Eikvil, Line; Jenssen, Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-12)
      Acoustic target classification in multi-frequency echosounder data is a major interest for the marine ecosystem and fishery management since it can potentially estimate the abundance or biomass of the species. A key problem of current methods is the heavy dependence on the manual categorization of data samples. As a solution, we propose a novel semi-supervised deep learning method leveraging a few ...
