VLE Measurements and Verification of a state-of-the-art Helmholtz Energy Equation of State for the Ternary Mixture of CO2-N2-CH4
(Master thesis, 2019)CO2 kan fanges i stor skala fra store punktkilder som kraftverk og/eller karbonintensiv industri. Når CO2-en fanges vil den ikke være ren, men inneholde flere forskjellige forurensninger i ulike konsentrasjoner avhengig ... -
VMAT for small cell lung cancer
(Master thesis, 2015)Limited stage small cell lung cancer (SCLC-LS) is an aggressive cancer form affecting a relatively small group of patients. The prognosis for these patients is poor, and those who are treated with radiotherapy often develop ... -
Volatile organic compound release across a permafrost-affected peatland
(Peer reviewed; Journal article, 2023)As the permafrost region experiences unprecedented climate warming, accelerated decomposition rates are potentially switching these cold landscapes to a hotspot of carbon emissions. In addition to the more widely studied ... -
Voltage control of superconducting exchange interaction and anomalous Josephson effect
(Journal article; Peer reviewed, 2019)Exerting control over the magnetic exchange interaction in heterostructures is of both basic interest and has potential for use in spin-based applications relying on quantum effects. We show that the sign of the exchange ... -
Voltage tuning of spin and charge supercurrents in a spin-active Josephson Junction
(Master thesis, 2018)Charge and spin-supercurrents in a spin-active Josephson junction is investigated through the quasiclassical theory of superconductivity. Analytical work has been performed and numerical results are presented, showing that ... -
Voltage-induced thin-film superconductivity in high magnetic fields
(Journal article; Peer reviewed, 2018)We predict that superconductivity in mesoscopic thin films can be stabilized in high magnetic fields if the superconductor is driven out of equilibrium by a DC voltage bias. For realistic material parameters and temperatures, ... -
A volume-averaged model for acoustic streaming induced by focused ultrasound in soft porous media
(Peer reviewed; Journal article, 2023)Equations describing acoustic streaming in soft, porous media driven by focused ultrasound are derived based on the assumption that acoustic waves pass through the porous material as if it were homogeneous. From these ... -
Vortex spin valve on a topological insulator
(Journal article; Peer reviewed, 2018)Spin-valve structures are usually associated with the ability to modify the resistance of electrical currents. We here demonstrate a profoundly different effect of a spin-valve. In combination with a topological insulator ... -
Vurdering av borevæske alternativer for Frigg feltutvikling
(Bachelor thesis, 2019)Valg av borevæsker er en vesentlig del av det teknologiske valget under planlegging av boreoperasjonen i feltutviklingsplanen. Den mest kostnadseffektive metoden er ønsket, men det miljømessige avtrykket er også et viktig ... -
Vurdering av GellyFeed metoden som hygienisering ved bruk av akvakulturdyr i fôr til akvakulturdyr. Uttalelse fra Faggruppe for fôr til terrestriske og akvatiske dyr i Vitenskapskomiteen for mattrygghet
(VKM Report;, Research report, 2008)Stiftelsen Rubin (senere GellyFeed AS) har siden 1991 jobbet med å utvikle fôr basert på avskjær fra villfisk til bruk i fôr til oppdrettsfisk. På grunn av fare for smitteoverføring, ble det utviklet et eget fôrkonsept ... -
Vurdering av nedbrytning basert på endringer i fysiske egenskaper for plasttekstil i lukkede oppdrettsanlegg
(Bachelor thesis, 2023)Dette er en oppgave som er skrevet i samarbeid med Maintech. Målet er å undersøke degraderingsegenskapene hos en plasttekstil som Fiizk benytter ved produksjon av dukposer for semi-lukkede oppdrettsmerder. Plasttekstilen ... -
Vurdering av Schaedler buljong for kultivasjon av anaerobe og kravfulle bakterier
(Bachelor thesis, 2021)Avdeling for Medisinsk Mikrobiologi på St. Olavs hospital bruker i dag Thioglycolat buljong som generelt anbefalt buljong for kultivasjon av anaerobe bakterier. I 2019 utførte avdelingen en preliminær studie, som viste at ... -
Vurdering av smitterisiko ved fôring av oppdrettsfisk med ubehandlet villfanget fisk. Uttalelse fra Faggruppe for dyrehelse og dyrevelferd (dyrevern) i Vitenskapskomiteen for mattrygghet
(VKM Report;, Research report, 2007)Vurderingen er utarbeidet etter forespørsel fra Mattilsynet i brev av 28. mars 2007 der Vitenskapskomiteen for mattrygghet (VKM) ble bedt om å foreta en vurdering av smitterisiko knyttet til bruk av ... -
Walker Breakdown in Magnon-Induced Ferromagnetic Domain Wall Motion
(Master thesis, 2015)We derive for the first time the collective coordinate equations for magnon-driven domain wall motion in ferromagnets from the Landau-Lifshitz-Gilbert equation. By performing a consistent calculation to second order we are ... -
Warmer and wetter winters: characteristics and implications of an extreme weather event in the High Arctic
(Journal article; Peer reviewed, 2014)One predicted consequence of global warming is an increased frequency of extreme weather events, such as heat waves, droughts, or heavy rainfalls. In parts of the Arctic, extreme warm spells and heavy rain-on-snow (ROS) ... -
