    • A prototype system for context sensitive communication in hospitals based on an Ascom/trixbox experimental platform 

      Gironi, Lorenzo (Master thesis; Mastergradsoppgave, 2011-06-01)
      Hospital's communication infrastructure suffers from different types of common problems. Currently, this infrastructure relies mainly on the use of pagers which are devices particularly interruptive for the daily work of hospital's workers, and moreover they do not support context-awareness communication. Wireless phones are supposed to be a valid alternative to pagers and they can also be used to ...

    • ProtoVAE: A Trustworthy Self-Explainable Prototypical Variational Model 

      Gautam, Srishti; Boubekki, Ahcene; Hansen, Stine; Salahuddin, Suaiba Amina; Jenssen, Robert; Hohne, Marina Marie-Claire; Kampffmeyer, Michael (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-10-15)
      The need for interpretable models has fostered the development of self-explainable classifiers. Prior approaches are either based on multi-stage optimization schemes, impacting the predictive performance of the model, or produce explanations that are not transparent, trustworthy or do not capture the diversity of the data. To address these shortcomings, we propose ProtoVAE, a variational autoencoder-based ...
    • Protracted post-glacial hydrocarbon seepage in the Barents Sea revealed by U–Th dating of seep carbonates 

      Himmler, Tobias; Wagner, Doris; Sahy, Diana; Vadakkepuliyambatta, Sunil; Chand, Shyam; Martma, Tõnu; Kirsimäe, Kalle; Mattingsdal, Rune; Panieri, Giuliana; Bünz, Stefan; Condon, Daniel J.; Knies, Jochen Manfred; Lepland, Aivo (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-01)
      The hydrocarbon seepage chronology during deglaciation across the formerly glaciated Barents Sea was established using uranium-thorium (U–Th) dating of seep carbonates. Seep carbonates were sampled with remotely operated vehicles (ROV) from the seafloor at three active hydrocarbon seeps (water depth 156–383 m), located in the north-west (Storfjordrenna), north-central (Storbanken High), and south-west ...

      Arlebrand, Berit Angelica; Augustsson, Carita; Escalona, Alejandro; Grundvåg, Sten-Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-06)
      This study examines the role of the depositional environment for the final reservoir quality in four Lower Cretaceous sandstone reservoirs in the southwestern Barents Sea by linking facies to the distribution of primary textures, composition, and diagenetic alteration. Facies analysis reveals slope-to-basin-floor, distal shallow-marine, and deltaic depositional environments. The slope-to-basin-floor ...
    • Proximal to distal grain-size distribution of basin-floor lobes: A study from the Battfjellet Formation, Central Tertiary Basin, Svalbard 

      Spychala, Yvonne T.; Ramaaker, Thymen A. B.; Eggenhuisen, Joris T.; Grundvåg, Sten-Andreas; Pohl, Florian; Wróblewska, Sara (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-09)
      The grain-size distribution of sediment particles is an important aspect of the architecture of submarine fans and lobes. It governs depositional sand quality and reflects distribution of particulate organic carbon and pollutants. Documenting the grain-size distribution of these deep-marine sedimentary bodies can also offer us an insight into the flows that deposited them. Submarine lobes ...
    • 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 ...
    • Psoriasis pathogenesis – Pso p27 constitutes a compact structure forming large aggregates 

      Lysvand, Hilde; Helland, Ronny; Hagen, Lars; Slupphaug, Geir; Iversen, Ole-Jan (Journal article; Tidsskriftartikkel, 2015-07)
      Psoriasis is a chronic inflammatory skin disease. The absence of microbial organisms as potential causal agents has given rise to the hypothesis that the inflammation is due to an autoimmune reaction. The defined inflamed areas of the skin lesions argue for an immunological disease with a local production of a causal antigen. Pso p27 is a protein generated in mast cells in psoriatic plaques, but ...
    • Psykososial beredskap sett i sammenheng med samfunnssikkerhet og beredskapsplanlegging. En dokumentanalyse av veiledere, lovverk og rapporter vedrørende psykososial beredskap 

      Hamborgstrøm, Aleksander (Master thesis; Mastergradsoppgave, 2017-06-01)
      Etter 22.juli har det vært et økt fokus på de psykiske effekter av kriser og katastrofer. Psykososial beredskap som ord og fenomen er relativt nytt og har forskjellige betydninger med tanke på hvilken teoretisk retting som beskriver fenomenet. Fenomenet har i liten grad blitt løftet opp mot et samfunnsfaglig aspekt, psykososial beredskapen har blitt brukt som samlebegrep for veldig mange temaer. ...
    • Pulsating aurora and cosmic noise absorption associated with growth-phase arcs 

      McKay, Derek; Partamies, Noora; Vierinen, Juha (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-18)
      The initial stage of a magnetospheric substorm is the growth phase, which typically lasts 1–2 h. During the growth phase, an equatorward moving, east–west extended, optical auroral arc is observed. This is called a growth-phase arc. This work aims to characterize the optical emission and riometer absorption signatures associated with growth-phase arcs of isolated substorms. This is done using ...

      The objective of this conceptual study is to reveal the substantial potential and synergy of solar energy and electric vehicles (EVs) working together. This potential is demonstrated by studying the feasibility of a nationwide energy system solely reliant on solar energy and EVs. Photovoltaic (PV) solar energy is already an important energy source globally, but due to its intermittency it requires ...
    • Purification and characterization of a salt tolerant metallo-beta-lactamase from Aliivibrio salmonicida 

      Kristiansen, Anders (Master thesis; Mastergradsoppgave, 2011-07)
      Beta-lactamases are enzymes that inactivate beta-lactam antibiotics by hydrolyzing the amide bond that exists in the beta-lactam ring, disrupting the ring structure and make the antibiotics nonfunctional against bacteria. Metallo-beta-lactamases (MBLs) are a group of beta-lactamases which needs metal ions bound to its active site in order to function and are an important factor in many bacteria in ...
    • Putative fossils of chemotrophic microbes preserved in seep carbonates from Vestnesa Ridge, off northwest Svalbard, Norway 

      Himmler, Tobias; Cremiere, Antoine; Birgel, Daniel; Wirth, Richard; Orphan, Victoria J.; Kirsimae, Kalle; Knies, Jochen; Peckmann, Jörn; Lepland, Aivo (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-20)
      The microbial key players at methane seeps are methanotrophic archaea and sulfate-reducing bacteria. They form spherical aggregates and jointly mediate the sulfate-dependent anaerobic oxidation of methane (SD–AOM: CH4 + SO42– → HCO3– + HS– + H2O), thereby inducing the precipitation of authigenic seep carbonates. While seep carbonates constitute valuable archives for molecular fossils of SD–AOM-mediating ...
