Operative Habitat Mapping and Monitoring in the Polar Night
(Chapter, 2020)The Polar Night has long been regarded as a period of no biological activity. As a logical consequence, environmental management has mainly been neglected in this period. We will use the Northguider accident in December ... -
OPFRs in e-waste plastic: problems and solutions in the circular economy
(Bachelor thesis, 2023)Etter ulike forbud og restriksjoner på flere bromerte flammehemmere (BFR) på grunn av deres giftige og persistente egenskaper, har bruken av de alternative fosfororganiske flammehemmerne (OPFR) økt betraktelig. OPFRer ble ... -

Opportunities of small-scale hydrogen production from MSWI fly ash
(Master thesis, 2022)Denne avhandlingen presenterer en innledende tekno-økonomisk vurdering av mulighetene for hydrogenproduksjon fra MSWI flyveaske. Arbeidet har blitt utført i samarbeid med selskapet NOAH, som driver anlegget for avfallshåndtering ... -
Opposing fitness consequences of habitat use in a harvested moose population
(Peer reviewed; Journal article, 2020)1. Landscape changes are happening at an unprecedented pace, and together with high levels of wildlife harvesting humans have a large effect on wildlife populations. A thorough knowledge of their combined influence on ... -
Opposite and dynamic regulation of the interferon response in metastatic and non-metastatic breast cancer
(Peer reviewed; Journal article, 2023)Background To our current understanding, solid tumors depend on suppressed local immune reactions, often elicited by the interaction between tumor cells and tumor microenvironment (TME) components. Despite an improved ... -
Oppstart av ferskvanns- og brakkvanns-biofilmreaktorer i RAS: Nitrifikasjonsaktivitet og mikrobiell samfunnstruktur
(Master thesis, 2019)Atlantisk laks (Salmo salar) i postsmoltfase er sårbar, og i sjømerder utsettes fisken for sykdommer og miljøbetinget stressfaktorer. En lenger oppholdsperiode i landbasert resirkulerende akvakultur system (RAS) kan redusere ... -
Opptak av mikroplast i hoppekrepsen Acartia tonsa.
(Bachelor thesis, 2016)Forurensning fra mikroplast er en forholdsvis ny miljøutfordring. Det er et stort forskningsbehov for å kartlegge påvirkninger av mikroplast på økosystemer. I denne oppgaven undersøkes opptak av mikroplast og alger i ... -
Optical and Electrochemical Characterisation of Carbon Anodes with Varying Porosity and Coke Quality
(Peer reviewed; Journal article, 2022)The performance of carbon anodes in aluminium production will depend on both the coke quality (impurities, structure) and the physical properties of the anode (density, permeability, electric resistivity). Here, a set of ... -
Optical and electrochemical characterization of carbon anodes in aluminum electrolysis
(Master thesis, 2021)Hovedmålet med dette prosjektet er å undersøke og analysere forbruk av karbonanoder i elektrolyse av aluminium og få litt innsikt potensielt kan forbedre effektiviteten til den nevnte prosessen og redusere totalt energi ... -
Optical Characterization of Intermediate Band Material
(Master thesis, 2023)I de kommende årene vil etterspørselen etter fornybar energi fortsette å øke, på grunn av de globale klimaendringene. Utvikling av solcelleteknologier med høyere effektivitet kan hjelpe til å takle denne utfordringen. ... -
Optical Coatings as Active Media for Mid-Infrared lasers
(Chapter, 2016)Thin films of Cr and Fe-doped ZnS with high infrared transparency have been deposited by molecular beam epitaxy and show optical properties suitable for use as active media in mid-infrared laser applications. -
Optical coatings for enhancement of the longitudinal Magneto-optic Kerr Effect from magnetic ultra-thin films
(Master thesis, 2011)The effect of optical coatings on the longitudinal magneto-optic Kerr effect response from 10 nm thin films of permalloy (Ni84Fe16) has been studied. Enhancement of the magneto-optic Kerr effect signal contrast of a factor ... -
