Cross-sectional associations between accelerometer-measured physical activity and hip bone mineral density. The Tromsø study 2015–2016
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-06)Positive associations between physical activity and bone health have been found in population-based studies, however, mostly based on self-reported physical activity. Therefore, we investigated the association between accelerometer-measured physical activity, measured in steps per day and minutes of moderate to vigorous physical activity (MVPA) per day, and total hip areal bone mineral density (aBMD) ... -

Mass cultivation of the marine diatom Porosira glacialis: Method development and comparison of pigment composition in response to irradiance wavelenght
(Master thesis; Mastergradsoppgave, 2022-05-19)In 2015, UiT The Arctic University of Norway and a local smelting plant initiated a project aiming to reduce the carbon footprint by mass cultivation of microalgae. The ability of the microalgae to directly capture industrially emitted CO2 and utilize wastewater as alternative nutrient sources to produce high value biomass, causes the bio-carbon recycling to represent both an environmental and ... -
Innstramminger i adgangen til innleie fra bemanningsforetak
(Master thesis; Mastergradsoppgave, 2023-05-19)Hovedregelen i norsk arbeidsliv er at arbeidstaker skal ansettes fast og på heltid. Denne hovedregelen er det bred enighet om, både blant de forskjellige politiske partiene og aktørene i arbeidslivet. Det har imidlertid vært uenighet rundt hvor stor adgangen til å gjøre unntak for hovedregelen bør være. 16. desember 2022 vedtok stortinget en lovendring som innebærer en innstramming av adgangen til ... -
γδ T-celler i atlantisk laks: Innsyn i γδ T-cellers roller i antivirale responser mot Piscine Orthoreovirus (PRV) oppnådd gjennom genomiske og molekylære analyser
(Master thesis; Mastergradsoppgave, 2022-05-18)Hos virveldyr med kjeve er αβ- eller γδ T-celler definert som de to hovedpopulasjonene av T-celler. Laksefamilien omfatter atlantisk laks og regnbueørret som er viktige arter i oppdrett. Oppdrett av disse artene avhenger av vaksiner for å kunne kultiveres på en bærekraftig måte. Dette har skapt økt interesse for å forstå mekanismene i adaptive immunresponser mot patogener og vaksiner, og derfor ... -

“Vulnerability” and Its Unintended Consequences
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-11)“Vulnerability” is now a widely used term in different settings—from politics and academia to everyday life. In response, a growing body of research has emerged critiquing and challenging the use of the concept in the social sciences. In this paper, we explore the use of the term vulnerability in research on children in out-of-home care and discuss the possible negative consequences of this—for the ... -
The cost of saying no: general practitioners’ gatekeeping role in sickness absence certification
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-02-12)Background General practitioners (GPs) have an important gatekeeping role in the Norwegian sickness insurance system. This role includes limiting access to paid sick leave when this is not justified according to sick leave criteria. 85% of GPs in Norway operate within a fee-for-service system that incentivises short consultations and high service provision. In this qualitative study, we explore ... -
Time is money: general practitioners’ reflections on the fee-for-service system
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-04-15)Background Fee-for-service is a common payment model for remunerating general practitioners (GPs) in OECD countries. In Norway, GPs earn two-thirds of their income through fee-for-service, which is determined by the number of consultations and procedures they register as fees. In general, fee-for-service incentivises many and short consultations and is associated with high service provision. GPs ... -
Characterization and prognostic value of lymphatic vessels in an oral tongue squamous cell carcinoma cohort
(Mastergradsoppgave; Master thesis, 2022-05-21)Tumor lymphangiogenesis increases the area of interaction between lymphatic vessels and tumor cells, and may thereby facilitate metastases. In oral cancer high lymphatic vessel density (LVD) and large lymphatic vessel area (LVA) have been associated with more aggressive tumors, but results from different studies are not conclusive. The aim of this study was to assess the association of tumor-associated ... -
Identification and semi-quantitative analysis of lipids in the diatom Porosira glacialis
(Mastergradsoppgave; Master thesis, 2022-05-18)Background: In 2015, The University of Tromsø initiated a project with local industry involving cultivation of marine microalgae to reduce industrial CO2-emissions. Marine microalgae are primary producers with high capacity for carbon fixation into biomass rich in lipids. Their lipid composition is characterized by high content of PUFAs such as EPA (20:5) and DHA (22:6). The biomass can potentially ... -
Ordningen «reseptfri medisin med veiledning» med fokus på Viagra Reseptfri® - farmasøyters erfaringer, og tanker rundt videreutvikling av ordningen
(Mastergradsoppgave; Master thesis, 2021-05-18)Bakgrunn: Apotekbransjen og farmasøytrollen er stadig i endring, og i de siste årene har flere og flere farmasøytiske tjenester blitt implementert i apotek. Dette har ført til større fokus på legemiddelveiledning og formidling av legemiddelinformasjon, samt apotek som et lavterskeltilbud innen helse. I 2018 åpnet Stortinget for å fjerne reseptplikten på enkelte legemidler, slik at de kunne selges ... -

From Trash to Treasure: The use of Lumpfish (Cyclopterus lumpus) as feed for Red King Crab (Paralithodes camtschaticus)
(Master thesis; Mastergradsoppgave, 2023-05-15)This thesis explores the potential of using farmed lumpfish (Cyclopterus lumpus), discarded from Atlantic salmon (Salmo salar L.) aquaculture industry, as a sustainable feed for juvenile red king crabs (Paralithodes camtschaticus). The red king crab has successfully established a self-sustaining population in the Barents Sea. With the red king crab being a large generalist predator, its impact on ... -
Systemic and mucosal stress responses of Atlantic salmon (Salmo salar) to peracetic acid
(Master thesis; Mastergradsoppgave, 2019-05-15)Infectious diseases are still a major problem in salmon aquaculture despite several attempts on developing prophylactic measures. Amoebic gill disease (AGD) is considered a growing threat in Norwegian salmon aquaculture. It has increased in prevalence and geographic distribution in the last years, resulting in considerable economic losses. Current treatments (i.e., freshwater and hydrogen peroxide ... -

Molecules and Morphotypes – Exploring benthic foraminiferal biodiversity in seep-influenced habitats
(Master thesis; Mastergradsoppgave, 2023-05-15)Beneath the seafloor, methane, a potent greenhouse gas, is trapped in ice-like structures, prone to destabilization and gas release in a warming climate. Gas releases through the seabed concentrated in seeps, creating unique ecosystems, hostile to some lifeforms but able to sustain others. Foraminifera have proved useful in biodiversity and ecosystem quality assessment due to their ubiquity in ...
