      Leyli, Amir Nadem; Jackson, Steven; Khawaja, Hassan; Moatamedi, Mojtaba (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-19)
      CO<sub>2</sub> emissions due to massive industrialization have led to several environmental issues. Carbon Capture and Storage (CCS) is one of the most important technologies that can be used to reduce anthropogenic CO<sub>2</sub> emissions worldwide. CCS projects mainly involve three processes: carbon capture, transportation, and storage. In the transportation process, the modeling of the flow in ...
    • The future of UN peace operations: Principled adaptation through phases of contraction, moderation, and renewal 

      Coning, Cedric de (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-05)
      This article considers the future of UN peace operations through a complexity theory lens. In the short-term peacekeeping will have to adapt to the consequences of the COVID-19 pandemic and the fall-out of the Trump presidency. In the medium-term peacekeeping will go through a phase of uncertainty and turbulence due to geopolitical power shifts in the global order. In the longer-term peacekeeping ...
    • The pure PV-EV energy system – A conceptual study of a nationwide energy system based solely on photovoltaics and electric vehicles 

      Boström, Tobias; Babar, Bilal; Hansen, Jonas Berg; Good, Clara (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-08)
      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 ...

      Ras GTPase-activating protein-binding proteins 1 and 2 (G3BP1 and G3BP2, respectively) are widely recognized as core components of stress granules (SGs). We report that G3BPs reside at the cytoplasmic surface of lysosomes. They act in a non-redundant manner to anchor the tuberous sclerosis complex (TSC) protein complex to lysosomes and suppress activation of the metabolic master regulator mechanistic ...
    • Samhandling og læring i et introduksjonsemne i fysikk basert på digital Peer Instruction 

      Winnberg, Øystein Grøntveit (Master thesis; Mastergradsoppgave, 2021-06-11)
      I de senere år har det vært en skifte mot økt bruk av digitale former for undervisning, og i 2020 ble dette spesielt framskyndet fordi brorparten av undervisningen på universitetsnivå måtte foregå digitalt på grunn av koronapendemien. Det er også voksende interesse for mer studentaktive undervisningsformer for å oppnå bedre læringsutbytte. Dette åpner for nye spørsmål rundt digitale studentaktive ...

    • Towards Unsupervised Domain Adaptation for Diabetic Retinopathy Detection in the Tromsø Eye Study 

      Størdal, Magnus (Mastergradsoppgave; Master thesis, 2021-05-29)
      Diabetic retinopathy (DR) is an eye disease which affects a third of the diabetic population. It is a preventable disease, but requires early detection for efficient treatment. While there has been increasing interest in applying deep learning techniques for DR detection in order to aid practitioners make more accurate diagnosis, these efforts are mainly focused on datasets that have been collected ...
    • Detecting Unhealthy Comments in Norwegian using BERT 

      Warholm, Joakim (Mastergradsoppgave; Master thesis, 2021-05-28)
      In this work we present a new Norwegian labeled dataset of 7078 comments for unhealthy comment detection. The dataset is used to fine-tune a BERT model, and demonstrates that BERT has the ability to detect subtle forms of toxicity, also in Norwegian. We compare how the different newly released Norwegian BERT models perform when fine-tuned on our dataset, and we also experiment with how English data ...
    • Learning Norwegian in Norwegian to become Norwegian? A study on the monolingual strategy for refugees learning Norwegian at Voksenopplæringen and how it affects their prospects for integration into society. 

      Mahdalchuk, Daniella (Mastergradsoppgave; Master thesis, 2021-05-18)
      Refugees in Norway are the group that experiences discrimination and social exclusion the most. The main reason of discrimination and unsuccessful integration is insufficient language skills. Even though, that they are provided with up to 3000 hours of language learning within an Introduction program that is specially designed for them to help them to reconstruct their lives in Norway, there is only ...

    • Valuing High Seas Ecosystem Conservation 

      Bui, Bich Xuân; Armstrong, Claire W.; Ankamah-Yeboah, Isaac; Hynes, Stephen; Needham, Katherine (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-16)
      The high seas provide a variety of ecosystem services that benefit society. There have, however, been few attempts to quantify the human welfare impacts of changes to the delivery of these benefits. We assessed the values of several key ecosystem service benefits derived from protecting ecosystems in the high seas of the Flemish Cap through choice experiments conducted in Canada, Norway, and Scotland. ...
    • Distracting stimuli evoke ventral tegmental area responses in rats during ongoing saccharin consumption 

      Peters, Kate Z.; Young, Andrew M J; McCutcheon, James Edgar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-11)
      Disruptions in attention, salience and increased distractibility are implicated in multiple psychiatric conditions. The ventral tegmental area (VTA) is a potential site for converging information about external stimuli and internal states to be integrated and guide adaptive behaviours. Given the dual role of dopamine signals in both driving ongoing behaviours (e.g., feeding) and monitoring salient ...
