    • Towards general and effective antifouling surfaces – covalent surface attachment of antimicrobial peptides 

      Karlsen, Eskil André (Doctoral thesis; Doktorgradsavhandling, 2025-08-26)
      <p>Healthcare-associated infections are of grave concern in healthcare facilities as these acquired infections pose a significant threat to the quality of life across the globe. Healthcare-associated infections are often related to the use of medical devices like catheters, joint prostheses, and implants. Medical devices are especially prone to bacterial growth, which can result in possible ...
    • Antifouling Efficacy on S. epidermidis of Nano-Au Surfaces Functionalized with Polyethylene Glycol (PEG)-Tethered Antimicrobial Peptides 

      Karlsen, Eskil André; Berglin, Mattias; Hansson, Adam; Lundgren, Anders Oskar; Svendsen, John Sigurd Mjøen (Journal article; Tidsskriftartikkel, 2025-05-15)
      Cationic antimicrobial peptides (cAMPs) kill bacteria in solution by membrane lysis; however, translating cAMPs into a covalently attached antibacterial coating is challenging since it remains unclear how the specifics of the conjugation impact the antifouling efficacy. Furthermore, studies have typically assessed cAMP coatings with a high and homogeneous surface coverage, although this may be ...
    • Constraining the environmental and biological controls on the geochemical composition of Neogloboquadrina pachyderma: Towards developing robust proxies for reconstructing polar surface ocean hydrography 

      Westgård, Adele (Doctoral thesis; Doktorgradsavhandling, 2025-08-13)
      <p>Rapid ongoing climate change includes warmer sea surface temperatures, salinity changes, reduced sea ice cover, and melting ice sheets in the polar regions. This has consequences for climate and society regionally and globally. However, there are large knowledge gaps regarding the sensitivity of these systems. Records of past changes in polar climate and ocean-cryosphere interactions can provide ...

In collaboration with AVJU, a Norwegian power ...
    • Developing General Guidelines for the Public Procurement of Artificial Intelligence in Digital Health Services in Norway: Addressing Legal and Practical Challenges 

      Krüger, Harald Anton (Master thesis, 2025)
      Abstract Background – Norwegian health trusts face significant challenges translating complex regulatory requirements from GDPR, the Medical Devices Regulation, the AI Act, NIS2, and public procurement law into concrete technical specifications for AI procurement. Current "one-size-fits-all" templates and prescriptive specifications often stifle innovation, overlook algorithmic risks, and expose ...
    • Cyberspace og ekstremisme: Sårbarheter, fellesskap og forebygging 

      Størseth, Madelen Kristine (Master thesis, 2025)
      Nasjonal trusselvurdering 2025 konstaterer at det er en økt bekymring rundt hvordan bruken av informasjons- og kommunikasjonsteknologi påvirker det sikkerhetspolitiske trusselbildet (PST, 2025). Det digitale skiftet har gitt opphav til et eget domene nemlig, cyberspace, hvor både samfunnsnyttige og skadelige aktiviteter finner sted. Cyberspace må derfor ikke bare forstås som teknologisk infrastruktur, ...

    • Thin Sea Ice Detection with CryoSat-2 

      Varland, Trym Fjeldstad (Master thesis, 2025)
      Arctic sea ice plays a vital role in the climate system, influencing atmospheric circulation, oceanic processes, and Arctic ecosystems. Thin sea ice is particularly important, as it governs seasonal transitions and contributes to feedback mechanisms such as Arctic amplification. Reliable estimates of sea ice thickness (SIT), especially within the thin ice regimes (less than 1 m), are essential for ...
    • Flaming Auroral Rays - An analysis of high-speed spectral imaging and time-dependent electron-transport modelling of precipitation 

      Sivertsen, Benedicte Havn (Master thesis, 2025)
      The current understanding of flaming auroral rays is that they are produced by short bursts of electrons precipitating down into the upper atmosphere. The altitude variation of the ionospheric response to such electron precipitation will be dependent on the energy-time dispersion of the incoming electron-bursts. The aim of this project has been to investigate the source of flaming auroral rays, ...
    • Feasibility Study of Space-Based Techniques for Measuring Millimeter-Scale Orbital Debris Flux 

      Sinnathamby, Abera (Master thesis, 2025)
      The increasing density of space debris poses a growing threat to satellite operations and future missions. While sub-millimeter debris is studied through impact craters and objects larger than 0.5 cm are tracked by ground-based radar, debris in the 1–3.2 mm range remains largely unmonitored. This thesis investigates the feasibility of using space-based techniques to estimate the flux of millimeter-scale ...
    • En studie om Ofotbanens klimaberedskap 

      Mathisen, Frida Aurora (Master thesis, 2025)
      Resiliens er et fagområde det forskes mye på for tiden, dog er det fortsatt stor uenighet og lite konsensus om hva resiliens er og hvordan det kan måles. Det er opp gjennom de siste årene framlagt ulike metoder for å kunne måle nivået av resiliens i en infrastruktur, uten at dette har ført til en foretrukken og allmenn metode. Denne studien tar for seg Critical infrastructure resilience index (CIRI) ...
    • Hvordan forebygge ungdomskriminalitet? 

      Abuhabib, Mohammed (Master thesis, 2025)
      Denne studien undersøker hvordan dagens forebyggende tiltak mot ungdomskriminalitet fungerer i en norsk kontekst. Problemstillingen utforskes gjennom tre forskningsspørsmål som retter søkelyset mot sentrale aktører og deres strategier, hvordan forebygging praktiseres i hverdagen, og hvilke utfordringer som oppstår i det tverrsektorielle samarbeidet. Studien er avgrenset til en konkret delbydel som ...
    • Indigenous identity in South Africa post 1994 and the peculiarity of Each Community with respect to the notion of Indigeneity 

      Medupe, Tshegofatso Constance (Master thesis, 2025)
      Identity is an inherent description and when defined, can also be nuanced depending on which perspective is taken. Indigenous identity is complex, and self-identification is one of the aspects that cannot be taken away from persons, being rooted in one-self’s acclamation, as indigenous in Africa, and South Africa. Indigenous identity is a dynamic and complex socio philosophical notion in South ...
    • Støypåvirket jobbtrivsel blant sysselsatte: risikofaktorer og yrkesforskjeller En deskriptiv analyse med data fra HUNT studien 

      Dahlen, Karoline Engseth (Master thesis, 2025)
      1 Sammendrag 1.1 Bakgrunn Støyeksponering er en viktig modifiserbar risikofaktor for utvikling av hørselstap og påvirket jobbtrivsel. Det er i dag dokumentert flere risikofaktorer for nedsatt hørsel, hvor høy alder og støyeksponering er viktigst. For å tilrettelegge for at arbeidslivet er tilgjengelig for så mange som mulig, så lenge som mulig, er god jobbtrivsel en viktig faktor. Denne studien ...

      Hussain, Fatima; Mobakk, Mari (Master thesis, 2025)
      Sammendrag Målet med oppgaven er å bedre kjønnsbalansen for lederroller i mannsdominerte bransjer. På bakgrunn av dette har vi valgt problemstillingen: Hvilke faktorer fremmer og hemmer kvinner i å oppnå en lederstilling i samferdselssektoren, eiendoms-, bygg- og anleggsbransjen? For at vi skal kunne besvare problemstillingen har vi sett på både internasjonale og norske studier som belyser barrierer ...
    • Termisk droneovervåkning av fjellrype - En evaluering av dronebasert metode for å oppdage fjellryper med termisk kamera 

      Malones, Thomas Dale (Master thesis, 2025)
      Sammendrag Bærekraftig forvaltning av jaktbare arter krever pålitelige overvåkningsmetoder. Fjellrype (Lagopus muta) er en populær art blant jegere i Norge, men som vi mangler effektive overvåkningsmetoder for. I denne studien ble det brukt en DJI Matrice 30T drone med RBG- og TIR-kamera for å undersøke om sensorene kan brukes til overvåkning av fjellryper. Studien har også undersøkt hvilke ...
    • Modelling of Snow Particle Settling Dynamics in Boundary Layer Turbulence: Evaluating Maxey-Riley and Reduced-Order Models with Nonlinear Drag 

      Haraldsson, Karolina (Master thesis, 2025)
      Accurately modelling snow particle settling dynamics in the atmospheric boundary layer remains a fundamental challenge. These dynamics influence snowfall transport and ground snow accumulation which in turn impact hydrology, weather predictions, and climate modelling. While the foundational work of Maxey and Riley (1983), which introduced equations describing inertial particles in a fluid flow, has ...
