Investigation of a Water Fraction Meter Based on the High Frequency Electromagnetic Field Technique Using an Uninsulated Inside Coil
(Master thesis, 2013)An uninsulated inside coil configuration of the water fraction meter designed by Hammertech AS has been investigated. The general principle behind the water fraction meter is to detect induced eddy currents in conductive ... -
Investigation of Adsorption of Surfactants onto Illite and Relations to Enhanced Oil Recovery Methods
(Master thesis, 2014)Surfactants have many applications in enhanced oil recovery (EOR) and for each of these applications, care must be taken in selecting the right surfactant. Surfactants tend to be a major portion of the costs associated ... -
Investigation of Adsorption of Surfactants onto Kaolinite and Relations to Enhanced Oil Recovery Methods
(Master thesis, 2014)Surfactant flooding is a well-established enhanced oil recovery (EOR) technique, but the economic feasibility of this method is a major concern due to the substantial misplacement and loss of expensive surfactants to the ... -
Investigation of aggressive behaviour of farmed Atlantic salmon towards different sized cleaner fish models.
(Master thesis, 2023)Bruk av rensefisk for å redusere lakselus innenfor produksjon av Atlantisk laks er blitt en normal praksis i Norge. Industrien opplever utfordringer med høye dødelighetstall og uforklarlige tap av rensefisk. Denne studiens ... -
Investigation of bioactive properties of fish protein hydrolysates: Antioxidant activity and ACE inhibitory activity
(Master thesis, 2019)Utilstrekkelig utnyttelse av fiskerestråstoff er et av hovedproblemene for fiskeindustrien i dag. Ressursene i havet er begrensede, og restråstoff som ikke er godt nok utnyttet kan skape miljø-problemer og samtidig påvirke ... -
Investigation of bond strength and intermetallic phases in roll bonded steel-aluminium laminates at 150oC - Including the use of nickel interlayers
(Master thesis, 2018)This master's thesis investigates intermetallic growth and metallurgical bonding in cold roll-bonded steel-aluminium laminates. Commercially pure AA1080 aluminium alloy have been roll-bonded with two different steel types, ... -
Investigation of bubble distribution and evolution in solar cell quartz crucibles
(Master thesis, 2017)Quartz crucibles are, among other applications, used to produce monocrystalline silicon ingots for the solar cell industry. The crucibles must be of high purity as any gas bubbles or impurities close to the crucible-melt ... -
