    • The impact of interplay between electronic and steric effects on the synthesis and the linear and non-linear optical properties of diketopyrrolopyrrole bearing benzofuran moieties 

      Purc, Anna; Koszarna, Beata; Iachina, Irina; Friese, Daniel Henrik; Tasior, Mariusz; Sobczyk, Krzysztof; Pedzinski, Tomasz; Brewer, Jonathan; Gryko, Daniel T (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-07)
      An in-depth investigation of the reaction of substituted salicylaldehydes with chloroacetonitrile led to the development of new conditions for the synthesis of 2-cyanobenzofurans. The crucial improvement lies in the use of phase-transfer catalysis in the second step, i.e., intramolecular aldol type condensation. In a two-step process, the reactants were transformed into a library of 3,6-bis(ben ...

      The aim of this study first aims to forward our empirical knowledge of how older Sami experience healthcare encounters in Norway and what they expect in terms of future care services, and second, to forward our understanding of how more culturally safe services could be offered to the Sami population, 30 years after they were officially recognised as an Indigenous People. A qualitative interpretative ...
    • Limitations of Ice Accretion on Offshore Aquaculture Facilities 

      Marsden, Benjamin (Master thesis; Mastergradsoppgave, 2021-12-15)
      Sea spray icing is a constant risk for fish farms operating in cold climates, such as on the Northern Norwegian coast, and there must therefore exist methods to reduce this risk. This thesis discusses the consequences of ice accretion to the traditional plastic circular fish cage design, and how the cage reacts under the pressure of added mass from sea spray icing. The prediction of sea spray icing ...
    • Atopic disease in relation to Staphylococcus aureus carriage and spa type distribution in a subarctic adult population 

      Devold, Jonas Arvola (Master thesis; Mastergradsoppgave, 2019-06-02)
      Atopic diseases are common, and the atopic epidemic has ravaged through the westernized countries and is heading for the developing countries too. Despite being a common disease, however, treatment and diagnostic options are still lacking. The immune system and development of atopic disease are interconnected with the environment through exposures or lack thereof. The microbiota of the mucosal ...

      Skonseng, Marie (Master thesis; Mastergradsoppgave, 2021-06-01)
      Tema for avhandlingen er politi- og påtalemyndighetens adgang til å registrere DNA-profiler i identitetsregisteret fra personer som ikke har gitt samtykke.I en demokratisk rettsstat må politiets adgang til å iverksette visse tiltak være i samsvar med menneskerettighetene slik de er vernet i internasjonale og konstitusjonelle rammeverk. Avhandlingens problemstilling er om registreringsadgangen i det ...
    • Effect of healthcare personnel in e-health interventions on glycated haemoglobin in adults with type 2 diabetes - a systematic review 

      Johansen, Trine Bjerke; Jacobsen Jardim, Patricia Sofia (Master thesis; Mastergradsoppgave, 2019-05-30)
      This systematic review shows that providing e-health with tailored HCP feedback to patients with type 2 diabetes, does not have added health benefits when the control group also receives e-health. While all of the included studies had some reduction in HbA1c levels, none of the study groups reach treatment target of HbA1c, less than 7%. Furthermore, there was no clinically relevant impact on blood ...
    • Hjernevevsoksygenering som monitorering hos nevrointensivpasienter med traumatisk hjerneskade. En retrospektiv studie og kvalitetssikring ved Universitetssykehuset i Nord-Norge, Tromsø.

    • Thyroid hormone and seasonal rhythmicity 

      Dardente, Hugues; Hazlerigg, David; Ebling, Francis J.P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-02-26)
      Living organisms show seasonality in a wide array of functions such as reproduction, fattening, hibernation, and migration. At temperate latitudes, changes in photoperiod maintain the alignment of annual rhythms with predictable changes in the environment.The appropriate physiological response to changing photoperiod in mammals requires retinal detection of light and pineal secretion of melatonin, ...
    • Circuit-level analysis identifies target genes of sex steroids in ewe seasonal breeding 

      Lomet, Didier; Druart, Xavier; Hazlerigg, David; Beltramo, Massimiliano; Dardente, Hugues (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-15)
      Thyroid hormone (TH) and estradiol (E2) direct seasonal switches in ovine reproductive physiology. In sheep, as in other mammals and birds, control of thyrotropin (TSH) production by the pars tuberalis (PT) links photoperiod responsiveness to seasonal breeding. PT-derived TSH governs opposite seasonal patterns of the TH deiodinases Dio2/Dio3 expression in tanycytes of the neighboring medio-basal ...
    • Tidsbruk ved transport av akutte hjerneslagpasienter med to ulike helikoptertyper 

      Knudsen, Kristin Susanne Storøy (Master thesis; Mastergradsoppgave, 2021-06-01)
      Hjerneslag er en akutt tilstand som rammer omtrent 10 000 nordmenn årlig, rask behandling på sykehus er avgjørende for pasientens videre funksjonsnivå og overlevelse. Luftambulansetransport av denne pasientgruppen er derfor ofte nødvendig, spesielt i Nord-Norge med store avstander og lang vei til sykehus. UNN HF har to tilhørende helikopterbaser der det brukes ulike helikoptertyper, Agusta Westland ...
    • The Use of Foraminiferal Geochemistry to Investigate Methane Seepage at the Svyatogor Ridge, Arctic Ocean 

      Akinselure, Abidemi Alex (Master thesis; Mastergradsoppgave, 2022-05-12)
      Methane is a greenhouse gas contributing to contemporaneous global warming, and seepage is one of the ways through which it migrates from the deep sedimentary basins, all the way up to the hydro- and atmosphere. The study of methane seepage is still young as scientists are yet to discover most seep sites as well as seep associated biological species. A record of past methane seepage can be derived ...
    • Cellular and molecular mediators of intestinal fibrosis 

      Lawrance, Ian; Rogler, Gerhard; Bamias, Giorgos; Breynaert, Chrstine; Florholmen, Jon; Pellino, Gianluca; Reif, Shimon; Speca, Silvia; Latella, Giovanni (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-02)
      Intestinal fibrosis is a major complication of the inflammatory bowel diseases (IBD) and although inflammation is necessary for its development, it would appear that it plays a minor role in its progression as anti-inflammatory treatments in IBD do not prevent fibrosis once it has started. The processes that regulate fibrosis would thus appear to be distinct from those regulating inflammation and, ...
