Desmozoon lepeophtherii as a pathogen in Norwegian salmon aquaculture
(Master thesis, 2011-06-01)During late summer and autumn 2008 the Norwegian Veterinary Institute Bergen received several diagnostic cases with similar histopathological changes. Due to unknown cause of the the condition it was subsequently called ... -
Desorption of sulfamethoxazole from polyamide 6 microplastics: Environmental factors, simulated gastrointestinal fluids, and desorption mechanisms
(Journal article; Peer reviewed, 2023)Microplastics (MPs) can enrich pollutants after being released into the environment, and the contaminants-loaded MPs are usually ingested by organisms, resulting in a potential dual biotoxic effect. In this paper, the ... -
"Det er vitenskapelig bevist at miljø er viktig" - En kvalitativ studie av hvordan ungdomsskoleelever bygger opp argumenter
(Master thesis, 2020-06-27)Argumentasjon og kritisk tenkning trekkes frem som to viktige begreper i den nye læreplanen. Dette er en av årsakene til at jeg i denne masteroppgaven har ønsket å studere hvordan elever bygger opp argumenter. Den overordnede ... -
Det regionale i det internasjonale - en internasjonaliseringsstrategi for høyskolene på Vestlandet
(Chapter, 2018)Fra å starte som rene undervisningsinstitusjoner har høyskolene nå fått krav om å være relevante i en forskningssammenheng. Spørsmålet er da – hvordan kan små institusjoner i utkanten av verden operere internasjonalt? Mitt ... -
«Det var jo en åpenbaring. Blir nesten som om vi har oppdaget en ny religion!» En casestudie av et utforskende Matematikk 1T-klasserom.
(Master thesis, 2022-06-01)Denne masteroppgaven presenterer en casestudie som ser på hvordan en erfaren og engasjert matematikklærer kan få til et utforskende klasserom, der læring skjer i samhandling mellom elevene. Målet med forskningsprosjektet ... -
Detailed lithospheric structure of an arc-continent collision beneathTaiwan revealed by joint inversion of seismological and gravity data
(Peer reviewed; Journal article, 2019)The largest compilation of seismological and gravimetry data are combined in a sequential inversion to shed light on unresolved crustal structures in Northern Taiwan and Southernmost Ryukyu area. Our density and seismic ... -
Detaljkartlegging av skredfare i Mobergslia, Os kommune, Hordaland
(Master thesis, 2011)Detaljert kartlegging av lausmassane, med hovudfokus på skredavsetjingar og kartlegging av skredfare er utført i området rundt Mobergslia, sør for Liafjellet i Os kommune, Hordaland. Det er laga eit lausmassekart og eit ... -
Detecting anaerobic methane oxidation coupled to sulfate reduction in hydrothermal sediments
(Master thesis, 2022-03-07)The barite field is a low-temperature vent field, characterized by microbial activity and high fluid values of $NH_4$, $SO_4^{2-}$, and $CH_4$. Geochemical analysis indicates a hydrothermal system with a sedimentary input ... -
Detecting atmospheric rivers using persistent homology
(Master thesis, 2015-06-01)This master's thesis is a first investigation on the problem of seeing whether it is possible to detect atmospheric rivers using persistent homology. Two different computations are done and a basic analysis is made. In ... -
Detecting inosine in nanopore sequencing data with machine learning
(Master thesis, 2021-08-13)Detecting modifications in DNA has been a long-standing challenge in understanding the workings of the genome, particularly with regards to regulatory function. The currently most widely used sequencing technology, NGS, ... -
Detecting leakage of brine or CO2 through abandoned wells in a geological sequestration operation using pressure monitoring wells
(Peer reviewed; Journal article, 2011)For risk assessment, policy design and GHG emission accounting it is extremely important to know if any CO2 or brine has leaked from a geological sequestration (GS) operation. As such, it is important to understand if it ... -
Detecting multiscale karst features including hidden caves using microgravimetry in a Caledonian nappe setting: Mefjell massif, Norway.
(Peer reviewed; Journal article, 2018-11-20)Cave passages and karst features form negative density contrasts expressed in gravity field anomalies. We present an interpretation approach for microgravimetry, applicable for challenging geological settings with heterogeneous ... -

Detecting single amino acids and small peptides by combining isobaric tags and peptidomics
(Peer reviewed; Journal article, 2019)Single amino acids and small endogenous peptides play important roles in maintaining a properly functioning organism. These molecules are however currently only routinely identified in targeted approaches. In a small ... -
Detection and quantification of CO2 seepage in seawater using the stoichiometric Cseep method: Results from a recent subsea CO2 release experiment in the North Sea
(Journal article; Peer reviewed, 2021)Carbon Capture and Storage (CCS) is a potential significant mitigation strategy to combat climate change and ocean acidification. The technology is well understood but its current implementation must be scaled up nearly ... -
Detection and Timing of Gamma-Ray Pulsations from the 707 Hz Pulsar J0952−0607
(Journal article; Peer reviewed, 2019)The Low-Frequency Array radio telescope discovered the 707 Hz binary millisecond pulsar (MSP) J0952−0607 in a targeted radio pulsation search of an unidentified Fermi gamma-ray source. This source shows a weak energy flux ... -
Detection of CO2 in N2 and H2O using photoacoustics
(Master thesis, 2013-06-03)Photoacoustic spectroscopy is a technique where absorbed modulated light is released as heat, causing thermal expansion which can be detected using an acoustic transducer. It can be used to determine the absorption spectra ... -
Detection of ice core particles via deep neural networks
(Journal article; Peer reviewed, 2023)Insoluble particles in ice cores record signatures of past climate parameters like vegetation dynamics, volcanic activity, and aridity. For some of them, the analytical detection relies on intensive bench microscopy ... -
