Automatisk detektering av den Arterielle Input Funksjonen i DCE-MRI
(Master thesis, 2023-06-02)Formål: I moderne DCE-MRI bildeanalyse er AIF avgjørende for å få korrekte farmakokinetiske verdier. AIF kan ekstraheres enten halvautomatisk eller manuelt. Uansett metode er det imidlertid dårlig reproduserbarhet og risiko ... -
Biomechanical analysis of groin related strength training exercises for injury prevention
(Master thesis, 2022-07-31)Purpose: Groin injuries in soccer are a widespread problem in sports medicine. One certain strength exercise, the Copenhagen adductor exercise, has shown an injury-preventing effect. But there are still many groin injuries, ... -
Biosurfactants as Anti-Agglomerants for Gas Hydrates
(Master thesis, 2013-08-14)Gas hydrate blockages in petroleum pipelines are considered a major hazard in the petroleum industry, and with increasing water content and decreasing temperatures, a solution is sought upon that is both environmentally ... -
Bruk av MRI og NMR-spektroskopi for å karakterisere fukteigenskapar ved ulike magnetiske feltstyrkar
(Master thesis, 2018-06-27)In this thesis, use of Nuclear Magnetic Resonance (NMR)-spectroscopy and Magnetic Resonance Imaging (MRI) is used to characterize pore size and wettability in a porous medium. NMR is a method that is increasingly used in ... -
Building a Combined Brightfield and Confocal Quantum Diamond Microscope for Imaging of Magnetic Samples
(Master thesis, 2021-08-02)The imaging of weak magnetic fields has been an important area of both research and technology. It continues to be an area that requires further research due to its potential wealth of applications. One magnetic field ... -
Caesium-137 in sediments from two Norwegian fjords- Including dating sediment cores
(Master thesis, 2010-05-31)Summary The fission product Cs-137 is present in all parts of the Norwegian environment, brought here atmospherically or by ocean currents. The most important sources are fallout from atmospheric nuclear weapons tests, ... -
Carotenoid content in algal epiphytes: A qualitative and quantitative DAD-HPLC analytical study
(Master thesis, 2023-06-01)A qualitative and quantitative study were performed on carotenoid content in algal epiphytes growing on the surface of Laminaria hyperborea. A stability study was also conducted to look at carotenoid degradation under ... -
Characterization and optimization study of Poly(N-isopropylacrylamide) (P(NIPAM)) and β-cyclodextrin (βCD) system for Controlled Release Drug Delivery Systems with NMR and MRI techniques
(Master thesis, 2022-08-10)This project is a direct continuation from my bachelor project that was based off Wisniewska,M (2017), where she investigated the changes in Poly(N-isopropylacrylamide) P(NIPAM) at the Volume Phase Transition (VPT) . The ... -
Characterization of complex solutions using relaxation- and diffusion weighted NMR Spectroscopy.
(Master thesis, 2017-08-02)The need for a sustainable replacement to the conventional fossil fuels is required. Biooils is a potential replacement. The biooil analyzed in this thesis is made from lignin, which is a by-product of paper production. ... -
Characterization of Linked Polymer Solutions (LPS) – Influence of salinity and divalent ions
(Master thesis, 2011-05-31)Water flooding with addition of polymers cross-linked by polyvalent ions (LPS) has proven to increase the oil recovery both in field applications and laboratory studies, but with constraints on the brine salinity. With of ... -
Characterizing Triacylglycerol in Cell Culture: Can LCMS replace HPTLC when assessing the effect of metformin in salmon in-vitro fatty liver model?
(Master thesis, 2017-10-25)Fatty liver, a health complication for aquacultured fish is developed by the deposition of triacylglycerol (TAG) within liver cells. Metformin has been proven to be an effective drug for ameliorating fatty liver in human ... -
