Application of MRI in studies of tetrahydrofuran hydrates in quartz sand at atmospheric pressure
(Master thesis, 2017-12-06)Natural gas hydrates form under low temperatures and high pressures. They can be found in abundance in permafrost environments and under the sea floor, where the temperature and pressure conditions ensure their stability. ... -
Effect of Free Water Elimination on Diffusion Indices in Healthy Volunteers and Patients with Multiple Sclerosis
(Master thesis, 2018-11-08)Diffusion tensor imaging (DTI) is a technique in magnetic resonance imaging (MRI) that can be used to image the brain microstructure beyond the resolution that is achievable using conventional imaging. By utilizing DTI, it ... -
An Experimental Study of Methane Hydrates in Sandstone Cores
(Master thesis, 2015-05-31)Natural gas hydrates exist in large quantities around the world, located in the subsurface of permafrost and oceanic environments. Future energy harvest from production of methane gas encapsulated in natural gas hydrates ... -
Magnetic Resonance Imaging of Hydrate Phase Transitions in Sediments
(Master thesis, 2017-12-21)Natural gas hydrates, simplified described as gas compressed in ice, are a substance existing in large quantities around the world. Their existence requires elevated pressures and low temperature. They are therefore found ... -
Teknologi for MRI av hjernens funksjon og biokjemiske sammensetning
(Master thesis, 2018-04-07)This thesis is divided into two parts. The first part addresses synchronisation between the rate of frequency the MR system used for fMRI examinations at Haukeland universitetssjukehus operates on (10 Mhz) and the sampling ... -
Transport and storage of CO2 in natural gas hydrate reservoirs
(Peer reviewed; Journal article, 2009-02)Storage of CO2 in natural gas hydrate reservoirs may offer stable long term deposition of a greenhouse gas while benefiting from methane production, without requiring heat. By exposing hydrate to a thermodynamically preferred ...
