Circulating delta-like Notch ligand 1 is correlated with cardiac allograft vasculopathy and suppressed in heart transplant recipients on everolimus-based immunosuppression
(Journal article; Tidsskriftartikkel, 2018-10-12)Cardiac allograft vasculopathy (CAV) causes heart failure after heart transplantation (HTx), but its pathogenesis is incompletely understood. Notch signaling, possibly modulated by everolimus (EVR), is essential for processes involved in CAV. We hypothesized that circulating Notch ligands would be dysregulated after HTx. We studied circulating delta‐like Notch ligand 1 (DLL1) and periostin (POSTN) ... -
Role of the Complement System in the Pathogenesis of Venous Thromboembolism
(Doctoral thesis; Doktorgradsavhandling, 2019-04-02)Venous thromboembolism (VTE) is a common disease with serious short- and long-term complications. VTE is a collective term for deep vein thrombosis (DVT) and pulmonary embolism (PE) and is the third most common cardiovascular disease, causing significant morbidity and mortality. Despite preventive strategies, the incidence of VTE has been stable or increasing slightly during the last decades, affecting ... -
Expression and functional properties of selected miRNAs in human cancer tissue and cancer cell lines
(Doctoral thesis; Doktorgradsavhandling, 2019-03-01)MicroRNAs (miRNAs) are small non-coding RNAs (ncRNAs) involved in the regulation of gene expression, and they are often seen dysregulated in cancer. For this reason, it is of great scientific interest to study these ncRNAs to better understand their distribution in human tissues and their mode of function. Based on a comprehensive miRNA microarray from 108 breast cancers in the Norwegian Woman and ... -
"Søringer" på vandring i nord. En sosiokulturell-lingvistisk studie av språklig identitet og tilhørighet hos fire flyttere fra Oslo til Tromsø
(Master thesis; Mastergradsoppgave, 2018-11-15)Det å flytte utløser refleksjoner om språk, sted, identitet og tilhørighet, og denne masteroppgava retter søkelyset mot disse refleksjonene. Formålet med denne sosiokulturell-lingvistiske studien er nærmere bestemt å utforske hvordan en flytteprosess påvirker oppfatninger om språklig identitet og tilhørighet hos fire flyttere fra Oslo til Tromsø. Mens tidligere sosiolingvistiske studier har studert ... -
Ecophysiological Responses of Sea Ice Algae and Phytoplankton to a Changing Arctic
(Doctoral thesis; Doktorgradsavhandling, 2019-03-29)The ice-covered seas of the Arctic have two major types of primary producers; phytoplankton growing in open waters and sea ice algae growing within and on the underside of the sea ice. This thesis investigates the controlling role of light availability on Arctic pelagic and sympagic (i.e. ice-associated) algae, and how light-induced responses are modulated by NO3 and pCO2 levels. A combination of ... -
Incorporating Incidence Angle Variation into Sar Image Segmentation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-05)We present a new approach for incorporating incidence angle derived synthetic aperture radar (SAR) brightness variation directly into SAR image analysis. This approach is unique in that the incidence angle dependency is modeled explicitly into the probability density function rather than an image-wide pre-processing `correction'. It can then be used for supervised and unsupervised image analysis, ... -
Så du det ikke? Objektsveksling av det med nominale og ikke-nominale antesedenter
(Master thesis; Mastergradsoppgave, 2018-10-31)Denne masteroppgaven omhandler objektsveksling av den pronominale anaforen det med nominale og ikke-nominale antesedenter. Objektsveksling i fastlandskandinaviske språk går ut på at bestemte trykksvake pronominale objekter veksler på tvers av negasjon og eventuelle adverb i en setning. Dette vil si at objektene flytter til en posisjon til venstre for negasjon/adverb. Den pronominale anaforen det kan ... -
"Det var på den tiden hun begynte å komme oftere". Erlend Loes Tatt av kvinnen adaptert til film
(Master thesis; Mastergradsoppgave, 2018-10-30)Sammendrag «Det var på den tiden hun begynte å komme oftere». Slik introduseres den kvinnelige hovedpersonen Marianne i Erlend Loes første roman Tatt av kvinnen (1993). Marianne nøyer seg ikke med å komme oftere, på kort tid invaderer hun livet til den navnløse hovedpersonen, som i liten grad klarer å tydeliggjøre for Marianne hvordan han opplever det. I min masteroppgave sammenligner jeg romanen ... -
The effect of temperature and precipitation on the leaching of contaminants from Ballangen tailings deposit, Norway
(Journal article; Peer reviewed, 2019)Leaching and transport of contaminants from tailings deposit is a highly complex interacting system affected by a suite of environmental factors, among which temperature and precipitation rates linked to climate change are two important parameters. The climate change in the Nordic region is more drastic than other regions. In this study, a laboratory batch leaching experiment was performed on the ... -

In Home we trust. An ethnographic study of mental health and the use of traditional medicine in a North Norwegian community
(Doctoral thesis; Doktorgradsavhandling, 2019-05-24)Traditional healing practices used when faced with illness or crisis, exist in many North Norwegian communities. Northern Troms has a historical multi-ethnicity of Sami, Kven and Norwegian. The notion of culture appears ambivalent and ambiguous, particularly concerning the Sami identity, but cultural diversity is nevertheless manifested through the use of traditional healing practices such as reading. ... -
Implementation of ecosystem-based ocean management
(Doctoral thesis; Doktorgradsavhandling, 2019-03-29)Ecosystem-based management (EBM) is a holistic approach for nature management that aims at achieving the good health and sustainable use of ecosystems. It is a complex and challenging concept: understanding ecosystems and human impacts upon them is complicated, there are demanding needs for collaboration and harmonisation of approaches and policies, and many conflicting interests must be balanced. ... -
On the causes of Arctic sea ice in the warm Early Pliocene
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-30)Scattered and indirect evidence suggests that sea ice occurred as far south as the Iceland Sea during the Early Pliocene, when the global climate was warmer than present. However, conclusive evidence as well as potential mechanisms governing sea ice occurrence outside the Arctic Ocean during a time with elevated greenhouse gas concentrations are still elusive. Here we present a suite of organic ... -
Procrastination and personal finances: Exploring the roles of planning and financial self-efficacy
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-05)Procrastination is related to unhealthy personal financial behaviors, such as postponing retirement savings, last minute shopping, and not paying bills on time. The present paper explores factors that could explain why procrastinators demonstrate more financial problems compared to non-procrastinators. Study 1 (N = 675) focused on planning, as both procrastination and poor financial habits are ... -

Beslutningstaking i barnevern. Norske saksbehandleres risikovurdering og tiltaksanbefaling
(Master thesis; Mastergradsoppgave, 2018-05-15)Saksbehandlere i barnevernet står gjennom sitt arbeid, overfor beslutninger som har konsekvenser for barnet, deres familier og deres nettverk. Beslutninger som foretas i en barnevernkontekst er avhengig av saksbehandlernes vurdering av risiko for barnet, og påfølgende tiltaksanbefaling skal reflektere beste alternativ for å håndtere vurdert risiko. De sakene som saksbehandlerne i barnevernet kan ... -

Undersøkelse i barnevernet. En kvalitativ studie om saksbehandleres arbeid i undersøkelsesfasen.
(Master thesis; Mastergradsoppgave, 2018-04-25)Barneverntjenestene i Norge har myndighet til å gjøre store inngrep i private folks liv. Vurderinger og beslutninger som fattes, kan få konsekvenser for de enkelte barn og familier som kommer i kontakt med tjenesten, som kan oppleves både positivt og negativ. Intensjonen bak og grunnlaget for at vi en skal ha en slik tjeneste er å ivareta barns rettigheter, samt for å sikre gode nok oppvekstvillkår ... -
A sharp boundedness result for restricted maximal operators of Vilenkin-Fourier series on martingale Hardy spaces
(Journal article; Peer reviewed, 2018-09-20)The restricted maximal operators of partial sums with respect to bounded Vilenkin systems are investigated. We derive the maximal subspace of positive numbers, for which this operator is bounded from the Hardy space H p to the Lebesgue space L p for all 0<p≤1 . We also prove that the result is sharp in a particular sense.
