    • The Potential Role of Marine Fungi in Plastic Degradation – A Review 

      Zeghal, Emna; Vaksmaa, Annika; Vielfaure, Hortense; Boekhout, Teun; Niemann, Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-29)
      Plastic debris has been accumulating in the marine realm since the start of plastic mass production in the 1950s. Due to the adverse effects on ocean life, the fate of plastics in the marine environment is an increasingly important environmental issue. Microbial degradation, in addition to weathering, has been identified as a potentially relevant breakdown route for marine plastic debris. Although ...
    • Information Requirements under the Essential-Use Concept: PFAS Case Studies 

      Glüge, Juliane; London, Rachel; Cousins, Ian T.; Dewitt, Jamie; Goldenman, Gretta; Herzke, Dorte; Lohmann, Rainer; Miller, Mark; Ng, Carla A.; Patton, Sharyle; Trier, Xenia; Wang, Zhanyun; Scheringer, Martin (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-05)
      Per- and polyfluoroalkyl substances (PFAS) are a class of substances for which there are widespread concerns about their extreme persistence in combination with toxic effects. It has been argued that PFAS should only be employed in those uses that are necessary for health or safety or are critical for the functioning of society and where no alternatives are available (“essential-use concept”). ...
    • Environmental constraints, biological growth and fleet dynamics of a developing fishery: A model study of the Barents Sea snow crab (Chionoecetes opilio, Majidae) fishery 

      Hogrenning, Egil; Eide, Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-07)
      The snow crab (Chionoecetes opilio, Majidae) has recently entered the Barents Sea, and a crab fishery is developing. Information on how the crab appeared and where it is moving is limited. We study how the characteristics of the fleet may affect the further development of the fishery. A spatial model is constructed as a grid of cells given a carrying capacity for crab determined by environmental ...
    • Voice Onset Time in multilingual speakers: Italian heritage speakers in Germany with L3 English 

      Geiss, Miriam; Gumbsheimer, Sonja; Lloyd-Smith, Anika; Schmid, Svenja; Kupisch, Tanja (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-01)
      This study brings together two previously largely independent fields of multilingual language acquisition: heritage language and third language (L3) acquisition. We investigate the production of fortis and lenis stops in semi-naturalistic speech in the three languages of 20 heritage speakers (HSs) of Italian with German as a majority language and English as L3. The study aims to identify the extent ...

      Baryshnikova, Kristina (Master thesis; Mastergradsoppgave, 2016-12-08)
      Cruisebransjen har vist den høyeste veksten og utnyttelsen av kapasiteten blant samtlige turistindustrier de siste årene. Utvidet valg på om bord aktiviteter, fokuset på nye destinasjoner og naturopplevelser har bidratt til økt popularitet på cruise reiser. Til tross for økt interesse for bransjen, gjenstår flere av områder lite forsket. Det har vært mye diskusjon omkring implementering av Revenue ...
    • Factors associated with the level of prolactin in patients under remission from Alcohol Use Disorder: A gender perspective 

      Pandey, Susmita; Bolstad, Ingeborg; Lien, Lars; Bramness, Jørgen Gustav (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-07)
      Background: Prolactin mirrors the dopaminergic activity in the brain which is key to understanding alcohol use disorders (AUD). Still, patients with AUD are a heterogenous group and there seem to be gender differences in the relationship between alcohol use and the level of prolactin. In this study, we examined gender-wise relationship of alcohol use trait- and state-related factors with the level ...
    • The Dog That Didn't Bark: A New Interpretation of Hypsoporphyrin Spectra and the Question of Hypsocorroles 

      Ghosh, Abhik; Conradie, Jeanet (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-11)
      Nearly a half-century after Gouterman classified the UV–vis–NIR spectra of porphyrin derivatives as normal, hyper, or hypso, we propose a heretofore unsuspected “mechanism” underlying hypso spectra. Hypsoporphyrins, which exhibit blueshifted optical spectra relative to normal porphyrins (such as Zn porphyrins), typically involve dn transition metal ions, where n > 6. The spectral blueshifts have ...
    • Fibroblast growth factor 2 conjugated with monomethyl auristatin E inhibits tumor growth in a mouse model 

      Krzyscik, Mateusz Adam; Zakrzewska, Malgorzata; Sørensen, Vigdis; Øy, Geir Frode; Bruheim, Skjalg; Haugsten, Ellen Margrethe; Mælandsmo, Gunhild Mari; Wiedlocha, Antoni; Otlewski, Jacek (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-20)
      Worldwide, cancer is the second leading cause of death. Regardless of the continuous progress in medicine, we still do not have a fully effective anti-cancer therapy. Therefore, the search for new targeted anti-cancer drugs is still an unmet need. Here, we present novel protein–drug conjugates that inhibit tumor growth in a mouse model of human breast cancer. We developed conjugates based on fibroblast ...
    • Patterns and predictors of drug use : a pharmacoepidemiologic study, linking the analgesic drug prescription to a population health survey in Tromsø, Norway 

      Eggen, Anne Elise (Doctoral thesis; Doktorgradsavhandling, 1994)
      The purpose of the study may be summarized as follows: - What is the frequency of drug use in the population, frequency of analgesic drug use in general and particularly the use of controlled analgesics? - How will morbidity, demographic pattern and lifestyle characteristics influence this drug use, and which factors explain the observed differences in drug use?
    • Language history on fast forward: Innovations in heritage languages and diachronic change 

      Kupisch, Tanja; Polinsky, Maria (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-08)
      There has been a substantial amount of research on heritage language acquisition and diachronic change. Although recent work has increasingly pointed to parallels between those two areas, it remains unclear how systematic these are. In this paper, we provide a bird's eye view, illustrating how patterns of diachronic change are mirrored in heritage language grammars. In doing so, we focus on one of ...
    • The healthy faith : pregnancy outcome, risk of disease, cancer morbidity and mortality in Norwegian Seventh-Day Adventists 

      Fønnebø, Vinjar (Doctoral thesis; Doktorgradsavhandling, 1992)
      The aim of the present study was to examine the association between being a Seventh-Day Adventist and risk factors for disease, pregnancy outcome, cancer incidence, site-specific mortality and total mortality in an unselected Seventh-Day Adventist population.
    • Sensitivity to microvariation in bilingual acquisition: Morphophonological gender cues in Russian heritage language 

      Mitrofanova, Natalia; Urek, Olga; Rodina, Yulia; Westergaard, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-27)
      Previous research on the acquisition of grammatical gender has shown that this property is acquired early in transparent gender systems such as Russian. However, it is not clear to what extent children are sensitive to the assignment cues and to what extent they simply memorize correspondences between frequent lexical items. Furthermore, we do not know if bilingual children are different from ...
    • A single step three-strain in vivo Gateway reaction 

      Gillman, Aaron Nicholas; Helleux, Alexandra; Abel, Sören (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-18)
      We developed a simplified, highly efficient Gateway reaction that recombines target DNA to expression (destination) plasmids in vivo and subsequently conjugates the final vector into a recipient strain, all in a single step. This recipient strain does not need to contain any selective marker and can be freely chosen as long as it is sensitive to ccdB counterselection and can be targeted by the RP4α ...
    • Nifedipine disturbs fetal cardiac function during hypoxemia in a chronic sheep model at near term gestation 

      Alanne, Leena; Bhide, Amarnath Govind; Lantto, Juulia; Huhta, Heikki; Kokki, Merja; Haapsamo, Mervi; Acharya, Ganesh; Rasanen, Juha (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11)
      Background: Nifedipine is a widely used drug in pregnancies complicated by maternal hypertensive disorders that can be associated with placental insufficiency and fetal hypoxemia. The evidence regarding fetal myocardial responses to nifedipine in hypoxemia is limited.<p> <p>Objective: We hypothesized that nifedipine would not impair fetal sheep cardiac function under hypoxemic environment. In ...
    • Quality of life among women with symptomatic, screen-detected, and interval breast cancer, and for women without breast cancer: a retrospective cross-sectional study from Norway 

      Moshina, Nataliia; Falk, Ragnhild Sørum; Botteri, Edoardo; Larsen, Marthe; Akslen, Lars Andreas; Cairns, John Alexander; Hofvind, Solveig (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-26)
      Purpose - Breast cancers detected at screening need less aggressive treatment compared to breast cancers detected due to symptoms. The evidence on the quality of life associated with screen-detected versus symptomatic breast cancer is sparse. This study aimed to compare quality of life among Norwegian women with symptomatic, screen-detected and interval breast cancer, and women without breast cancer ...
    • Material Methods for a Rapid-Response Anthropology 

      Magnani, Natalia; Magnani, Matthew (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-13)
      Sudden crises frustrate anthropological methodologies. Our discipline aspires to engaged scholarship in dialogue with community and public concerns. Yet timely social analysis must address the ephemeral and unpredictable, running against the rhythm of anthropological fieldwork and publication. When social distancing precludes typical ethnographic engagements, how may we adapt anthropological approaches?
    • Virtual and augmented reality in social skills interventions for individuals with autism spectrum disorder: A scoping review 

      Dechsling, Anders; Orm, Stian; Kalandadze, Tamara; Sütterlin, Stefan; Øien, Roald A; Shic, Frederick; Nordahl-Hansen, Anders (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-16)
      In the last decade, there has been an increase in publications on technology-based interventions for autism spectrum disorder (ASD). Virtual reality based assessments and intervention tools are promising and have shown to be acceptable amongst individuals with ASD. This scoping review reports on 49 studies utilizing virtual reality and augmented reality technology in social skills interventions for ...

      Zhu, Hong; Andersen, Synnøve Thomassen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-17)
      This article discusses which knowledge areas of digital competence are vital for Norwegian social work education today basing on EU Digital Competence framework (DigComp) and expectation from frontline practice. The research adopted diverse methods for data collection, including a case study of Norwegian Labour and Welfare Administration (NAV), a document analysis of Norwegian social work education ...
    • Group bargaining in supply chains 

      Clark, Derek John; Pereau, Jean-Christophe (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-10)
      We consider a vertical supply chain in which a monopoly retailer produces a good by assembling a number of essential components each of which is owned by a monopoly. Rather than making the common assumption that the component price is set in the same way for each owner, we investigate the possibility that the retailer may profit by bargaining with some owners in a group, whilst others set their ...
