(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 ...
-
(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 ) ...

(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 / 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 ...
-
(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 ...

Validation of DNA metabarcoding as a tool for diet analysis in reindeer (Rangifer tarandus tarandus L.)Restricted Access (Master thesis / Masteroppgave, 2019)Free-ranging reindeer (Rangifer tarandus L.) eat a diverse diet of graminoids, herbs, shrubs, woody plants, mushroom, lichen and mosses. DNA metabarcoding is an established method in dietary studies and through e.g. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2008)Background Oligoarrays have become an accessible technique for exploring the transcriptome, but it is presently unclear how absolute transcript data from this technique compare to the data achieved with ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)Background One important physiological response to environmental stress in animals is change in gene expression. To obtain reliable data from gene expression studies using RT-qPCR it is important to evaluate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Constraints have traditionally been used to ensure data quality. Recently, several constraint languages such as SHACL, as well as mechanisms for constraint validation, have been proposed for Knowledge Graphs (KGs). KGs are ...
-
(Master thesis / Masteroppgave, 2017)This thesis deals with the validation of the NGU susceptibility map for debris slides/avalanches and small to medium sized debris flows. The susceptibility model developed by NGU is a nation-wide model, predicting source ...
