(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)The interaction of hydrogen (H) with lithium (Li) and zinc vacancies (VZn) in hydrothermally grown n-type zinc oxide (ZnO) has been investigated by positron annihilation spectroscopy (PAS) and secondary ion mass spectrometry. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)In cortex, the local field potential (LFP) is thought to mainly stem from correlated synaptic input to populations of geometrically aligned neurons. Computer models of single cortical pyramidal neurons showed that subthreshold ...
-
(Master thesis / Masteroppgave, 2016)As mobile technology becomes ever more ubiquitous, making the choice to travel by public transport has never been easier. Still, the car is the preferred mode of transport, even within the large cities. This thesis looks ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2009)Background Although some mechanisms of habitat adaptation of conspecific populations have been recently elucidated, the evolution of female preference has rarely been addressed as a force driving habitat ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Understanding why some hybrid zones are bimodal and others unimodal can aid in identifying barriers to gene exchange following secondary contact. The hybrid zone between the grasshoppers Chorthippus brunneus and C. jacobsi ...
-
(Master thesis / Masteroppgave, 2007)Breeding habitat-choice in two closely related species of passerines, Great Tit (Parus major) and Blue Tit (Cyanistes caereleus) was studied to reveal if their habitat preferences primarily is a hereditary trait, or if ...
-
Habitat Classification Based on Bottom Topography and its Predictability for Describing Polychaeta and Trait DistributionRestricted Access (Master thesis / Masteroppgave, 2011)There is an increasing demand for simple and cost-efficient methods for describing habitats, communities and distribution of organisms on the seabed for management, conservation and prediction of ecological patterns. To ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Habitat fragmentation has been suggested to be responsible for major genetic differentiations in a range of marine organisms. In this study, we combined genetic data and environmental information to unravel the relative ...
-
(Master thesis / Masteroppgave, 2016)Parids are mostly sedentary birds and therefore habitat selection is important for both winter survival and reproduction in the breeding season. Because of their residency, parids are vulnerable to habitat fragmentation ...
-
(Master thesis / Masteroppgave, 2007)The red deer (Cervus elaphus) are among the most important game species in Norway, with a tenfold increase in harvest over the last few decades. Despite its importance, information regarding red deer habitat selection is ...

(Master thesis / Hovedoppgave, 2007)De to makrofyttene Zostera marina (ålegress) og Fucus serratus (sagtang) har glatte overflater og kan synes relativt like som substrat for mobil fauna. Sagtang danner et mer eller mindre kontinuerlig belte langs hele kysten, ...
-
(Master thesis / Masteroppgave, 2006)Denne masteroppgaven går ut på å finne ut hva som karakteriserer hackere og crackere. Oppgaven tar opp temaer som begrepsdefinering, motivasjoner, moral, metoder, organisering og informasjonsflyt. For å finne ut av dette ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The Hall coefficient RH and electrical conductivity of misfit calcium cobalt oxide (Ca2CoO3−δ)q(CoO2) (CCO) were measured at room temperature for different oxygen vacancy concentrations δ. Based on these and numerous ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)The evolution of the virial overdensity Δvir for ΛCDM and seven dynamical dark-energy models is investigated in the extended spherical collapse model (SCM). Here the virialization process is naturally achieved by introducing ...
-
(Master thesis / Masteroppgave, 2013)Modified gravity theories are a popular research field in the hope that they could explain some of the unanswered questions in cosmology, for example how the universe starts, evolves and ends. One way to test proposed ...
-
(Master thesis / Masteroppgave, 2023)Haloformasjoner er optiske fenomener som kan sees på himmelen. Disse fenomenene oppstår på grunn av sollys som skinner igjennom tynne cirrusskyer. Cirrusskyer består av iskrystaller med ujevne former, i motsetning til ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Screened modified gravity predicts potentially large signatures in the peculiar velocity field that makes it an interesting probe to test gravity on cosmological scales. We investigate the signatures induced by the Symmetron ...
-
(Master thesis / Masteroppgave, 2015)Halodiazoacetater har nylig blitt anvendt i tre rhodium(II)-katalyserte reaksjonsveier, og har vist seg som en interessant gruppe diazoforbindelser fra et syntetisk perspektiv. Halodiazoacetatenes termiske stabilitet er ...
