(Doctoral thesis / Doktoravhandling, 2008)The present work is a study of the relationship between a quantum Hall system and its one-dimensional representation. The standard theory, which is based on general arguments, predicts that the edge of the quantum Hall ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2008)The role of vacancy clustering and acceptor activation on resistivity evolution in N ion-implanted n-type hydrothermally grown bulk ZnO has been investigated by positron annihilation spectroscopy, resistivity measurements, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)We have used depth-resolved cathodoluminescence, positron annihilation, and surface photovoltage spectroscopies to determine the energy levels of Zn vacancies and vacancy clusters in bulk ZnO crystals. Doppler broadening-measured ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The self-diffusion coefficients of palladium in PdHx (x = 0, 0.25, 0.5, 0.75, 1) were studied using density functional theory to obtain the required thermodynamic and kinetic parameters. The enthalpy of migration decreased ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The COVID-19 pandemic may be of particular concern for pregnant and breastfeeding women. We aimed to explore their beliefs about the coronavirus and COVID-19 vaccine willingness and to assess the impact of the pandemic on ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)A comparative study of vacuum versus ambient pressure inert gas thermogravimetry was performed on silver carboxylates compounds. Some of the complexes from this group have been previously successfully applied as precursors ...
-
(Master thesis / Masteroppgave, 2018)Sedimentary rocks from the Grønsennknippa area, located in Vestre Slidre in Valdres, have been studied by field investigations, remote sensing and laboratory techniques. The tectonostratigraphic setting has been briefly ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 1999)A mixed-valence state, formally denoted as Fe 2 . 5 + , is observed in the 300 K Mössbauer spectra of the most reduced samples of SmBaFe 2 O 5 + w . Upon cooling below the Verwey-type transition temperature (TV≈ 200 K ) ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Ni incorporation has been studied in a comprehensive range of Zn/Co-based magnetic oxides to elucidate its valence state and lattice incorporation. The resulting structural and magnetic properties of a range of related ...
-
(Master thesis / Hovedoppgave, 2002)Hovedoppgaven er en spørreundersøkelse om naturlegemiddelet Valerina Natt. Spørreundersøkelsen ble gjennomført ved hjelp av et spørreskjema som ble delt ut fra apotek til kunder som kjøpte Valerina Natt. 57 apotek i Oslo, ...
-
(Master thesis / Hovedoppgave, 2002)This thesis presents a framework for modeling and developing temporal information systems. The framework defines a model driven development process which automatically transforms temporal system models into executable ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The Devonian record presents an opportunity to test and validate an existing marine bioregionalization. This study is the first to use comparative biogeography and phylogenetic data to test Devonian bioregionalization. ...

-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Background and Purpose: The functional, communicative, and critical health literacy (FCCHL) scale is widely used for assessing health literacy (HL) in people with chronic diseases, such as type 2 diabetes (T2DM). Despite ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract One strong magnetic cloud (MC) with a magnetic field magnitude reaching ∼40 nT at 1 au during 2012 June 16–17 is examined in association with a preexisting magnetic flux rope (MFR) identified on the Sun. ...
-
(Master thesis / Hovedoppgave, 2002)In this cand.scient. thesis we propose a strategy for testing validity of decomposition of contract oriented specifications. The strategy is based on Abadi and Lamport's Composition Theorem for the Temporal Logic of Actions ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Background The use of HbA1c ≥6.5% for diagnosis of diabetes has been challenged for post-transplantation diabetes mellitus (PTDM) also known as new onset diabetes after transplantation (NODAT) due to a low ...
