Impact of Chronic Obstructive Respiratory Disease (COPD), respiratory symptoms and oxygen saturation on the risk of incident venous thromboembolism (VTE) and VTE-related mortality in a general population
(Doctoral thesis; Doktorgradsavhandling, 2019-11-01)<p>Venous thromboembolism (VTE) is a collective term for pulmonary embolism (PE) and deep vein thrombosis (DVT). Chronic Obstructive Pulmonary Disease (COPD) is described as a moderate risk factor for VTE, but the association has so far been scarcely examined. The aims of this thesis were to I) investigate the impact of COPD on the risk of incident VTE and the risk of mortality in COPD-patients with ... -
Compensatory task-specific hypersensitivity in bilateral planum temporale and right superior temporal gyrus during auditory rhythm and omission processing in Parkinson’s disease
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-02)Persons with Parkinson’s disease have general timing deficits and have difficulties in rhythm discrimination tasks. The basal ganglia, a crucial part of Parkinson’s disease pathology, is believed to play an important role in rhythm and beat processing, with a possible modulation of basal ganglia activity by level of rhythmic complexity. As dysfunction in basal ganglia impacts function in other brain ... -
An fMRI-study on single-sided deafness: Spectral-temporal properties and side of stimulation modulates hemispheric dominance
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-08-06)<i>Objective</i>: Our main aim was to investigate the blood oxygenation level dependent (BOLD) response to monaural and binaural speech- and non-speech stimuli as measured with fMRI in subjects with single-sided deafness and in normal hearing controls. We hypothesised that the response to monaural stimulation in both normal hearing subjects and persons with single-sided deafness would vary with the ... -

Dynamic up- and down-regulation of the default (DMN) and extrinsic (EMN) mode networks during alternating task-on and task-off periods
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-19)Using fMRI, Hugdahl et al. (2015) reported the existence of a general-domain cortical network during active task-processing which was non-specific to the cognitive task being processed. They labelled this network the extrinsic mode network (EMN). The EMN would be predicted to be negatively, or anti-correlated with the classic default mode network (DMN), typically observed during periods of rest, ... -
Microvariation in multilingual situations: The importance of property-by-property acquisition
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-12)In this article, I argue that first language (L1), second language (L2) and third language (L3) acquisition are fundamentally the same process, based on learning by parsing. Both child and adult learners are sensitive to fine linguistic distinctions, and language development takes place in small steps. While the bulk of the article focuses on crosslinguistic influence in L2/Ln acquisition, I first ... -

Mindre styring og mer autonomi? En studie av Kunnskapsdepartementets tildelingsbrev til universitet og høgskoler i Nord-Norge, i perioden 2006-2014
(Master thesis; Mastergradsoppgave, 2014-11-17)Temaet for denne oppgaven er balanseforholdet mellom behovet for statlig styring og autonomi i underliggende virksomhet. På den ene siden eksisterer et generelt ønske om å delegere oppgaver, myndighet og ansvar, men på den andre siden finnes det et markant behov for å sikre at de som blir tildelt større og mer omfattende autonomi faktisk er i stand til å innfri de krav som stilles til offentlige ... -
Microwave-assisted synthesis of heterocycles from aryldiazoacetates.
(Master thesis; Mastergradsoppgave, 2017-11-15)A novel microwave-assisted method for generation of heterocycles have been explored. A range of 3,4 dihydroquinoxalin-2-ones have been prepared via an N-H insertion/cyclization cascade of dinucleophiles and aryldiazoacetates in moderate to good yields (12 - 80%). Reactions of aryldiazoacetates with o-phenylenediamine generated the best yields, while reactions with aliphatic and benzylic dinucleophiles ... -
Surface Functionalization of Carbon Nanotubes for Energy Applications
(Peer reviewed; Chapter, 2018-05-05)Carbon nanotubes (CNTs) are receiving a great deal of attention as a catalyst support for different energy applications, due to their high surface area and high conductivity.

Typically, pristine CNTs (as produced) have no functional groups, which is usually considered as an ... -
Økosystemforvaltning - Hvorfor økonomisk analyse er viktig
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019)<p>I et økosystem vil noen arter være byttedyr, andre predatorer og mange begge deler, skiftende gjennom sitt livsløp. Så også i de marine økosystem der norske fiskere årlig fisker mellom 2 og 3 millioner tonn, noe som gjør at Norge er blant de 10 største fiskerinasjoner i verden. De fleste fiskebestander av stor kommersiell verdi har en utbredelse som innebærer at årlige totalkvoter fastsettes og ... -
