Punktprosessmodeller for linjetransektdata
(Master thesis, 2010-04-27)Oppgaven omhandler punktprosesser som modell for observasjoner ved en transektlinje. Hovedprosessen er en Markovmodulert Poissonprosess som tillater at punkter opptrer oftere i noen perioder enn andre, den er her begrenset ... -
Purcell-induced suppression of superradiance for molecular overlayers on noble atom surfaces
(Journal article; Peer reviewed, 2022)We study the impact of an environment on the electromagnetic responses of a molecule in the presence of a dielectric medium. By applying the dipole–dipole coupling between the molecule’s and the environment’s degrees of ... -
Purple anthocyanin colouration on lower (abaxial) leaf surface of Hemigraphis colorata (Acanthaceae)
(Peer reviewed; Journal article, 2014-09)The functional significance of anthocyanin colouration of lower (abaxial) leaf surfaces is not clear. Two anthocyanins, 5-O-methylcyanidin 3-O-(3″-(β-glucuronopyranosyl)-β-glucopyranoside) (1) and 5-O-methylcyanidin ... -
Pushing the limits of photoreception in twilight conditions: The rod-like cone retina of the deep-sea pearlsides
(Peer reviewed; Journal article, 2017)Most vertebrates have a duplex retina comprising two photoreceptor types, rods for dim-light (scotopic) vision and cones for bright-light (photopic) and color vision. However, deep-sea fishes are only active in dim-light ... -
Putative novel hydrogen- and iron-oxidizing sheath-producing Zetaproteobacteria thrive at the Fåvne deep-sea hydrothermal vent field
(Journal article; Peer reviewed, 2023)Iron-oxidizing Zetaproteobacteria are well known to colonize deep-sea hydrothermal vent fields around the world where iron-rich fluids are discharged into oxic seawater. How inter-field and intra-field differences in ... -
Putting small fish on the table: the underutilized potential of small indigenous fish to improve food and nutrition security in East Africa
(Journal article; Peer reviewed, 2023)Sub-Saharan Africa has a high prevalence of food insecurity. Small pelagic fish such as Silver cyprinid (Rastrineobola argentea) which is indigenous to Lake Victoria, can be a nutritious animal sourced food that contributes ... -
PVCap as kinetic hydrate inhibitor in gas-water system
(Master thesis, 2009-11-20)In this work, molecular dynamic (MD) simulations were employed on different model systems of practical and theoretical significance to investigate possible mechanisms of kinetic hydrate inhibition. Water/methane interface ... -
PVTx Properties of a Two-phase CO2 Jet from Ruptured Pipeline
(Peer reviewed; Journal article, 2013)Span and Wagner equation of state (SW EOS) have been used to investigate changes in the thermodynamic properties of CO2 during a depressurization process from a pipeline into marine environment. The process is assumed to ... -
PyProp - A Python Framework for Propagating the Time Dependent Schrödinger Equation
(Doctoral thesis, 2009-12-18) -
The pyramidellidae (gastropoda, heterobranchia) of Norway and adjacent waters. A taxonomic review
(Peer reviewed; Journal article, 2014)This monograph gives a taxonomic treatment of all 54 ‘species’ of Pyramidellidae reported from Norwegian and adjacent waters. Two species, Parthenina wikanderi n.sp.and Eulimella frielei n.sp., are described as new and ... -
Pyridine-Stabilized Fast-Initiating Ruthenium Monothiolate Catalysts for Z-Selective Olefin Metathesis
(Peer reviewed; Journal article, 2017)Pyridine as a stabilizing donor ligand drastically improves the performance of ruthenium monothiolate catalysts for olefin metathesis in comparison with previous versions based on a stabilizing benzylidene ether ligand. ... -
p−p, p−Λ, and Λ−Λ correlations studied via femtoscopy in pp reactions at √s=7 TeV
(Peer reviewed; Journal article, 2019-02)We report on the first femtoscopic measurement of baryon pairs, such as p − p , p − Λ , and Λ − Λ , measured by ALICE at the Large Hadron Collider (LHC) in proton-proton collisions at √ s = 7 TeV . This study demonstrates ... -
QALM - a tool for automating quantitative analysis of LC-MS-MS/MS data
(Master thesis, 2010-05-31)The goal of bioinformatics is to support science and research in the field of biology through the application of information technology. Proteomics is a field within biology that deals with the study of proteins. This paper ... -
QCD Parton Fragmentation in Vacuum and Medium with Leading Jet Energy-Loss

qPCR screening for Yersinia ruckeri clonal complex 1 against a background of putatively avirulent strains in Norwegian aquaculture
(Journal article; Peer reviewed, 2022)Although a number of genetically diverse Yersinia ruckeri strains are present in Norwegian aquaculture environments, most if not all outbreaks of yersiniosis in Atlantic salmon in Norway are associated with a single specific ... -
Qualification of New Methods for Measuring In-Situ Rheology of Non-Newtonian Fluids in Porous Media
(Journal article; Peer reviewed, 2020)Pressure drop (ΔP) versus volumetric injection rate (Q) data from linear core floods have typically been used to measure in situ rheology of non-Newtonian fluids in porous media. However, linear flow is characterized by ... -
Quality of the Analysis Step in EnKF
(Master thesis, 2011-06-15)In many physical applications we want to characterize the parameters of a system based on indirect observations or measurements. In a reservoir simulator setting, the goal is to simulate the production of hydrocarbons from ... -
Quantification and localization of StAR expression in Atlantic cod ovaries
(Master thesis, 2009-06-02)Steroidogenesis is essential for the production of sex steroids, and therefore also the sexual maturation process. The rate-limiting step in steroidogenesis is the movement of cholesterol from the outer to the inner ... -
Quantification and uncertainty of root growth stimulation by elevated CO2 in a mature temperate deciduous forest
(Journal article; Peer reviewed, 2023)Increasing CO2 levels are a major global challenge, and the potential mitigation of anthropogenic CO2 emissions by natural carbon sinks remains poorly understood. The uptake of elevated CO2 (eCO2) by the terrestrial ...
