Comparison of residual oil cluster size distribution, morphology and saturation in oil-wet and water-wet sandstone
We imaged an oil-wet sandstone at residual oil saturation (Sor) conditions using X-ray micro-tomography with a nominal voxel size of (9 μm)3 and monochromatic light from a synchrotron source. The sandstone was rendered ...
A polynomial-time algorithm for LO based on generalized logarithmic barrier functions
(Academic Publications, 2008)
Critical Measures and Parameter Space of Jenkins-Strebel Quadratic Differentials
(The University of Bergen, 2012-05-07)
The thesis is devoted to applications of the theory of quadratic differentials to the problems of construction of critical measures, that provide critical values of the logarithmic energy of a charge system on the ...
Stabilisation of Tyrosine Hydroxylase in Nanoparticles for Enzyme Replacement Therapy
(The University of Bergen, 2012-02-27)
The aim of this thesis has been to characterise nanoparticles (NPs) to which tyrosine hydroxylase (TH) was attached, as a preliminary step in their evaluation to be used for an enzyme replacement therapy (ERT) for ...
Characterization of Hyper Spectral Irradiance and Radiance Sensors
(The University of Bergen, 2013-09-11)
It is surprisingly problematic to to accurately measure light in the laboratory. Even more so when measuring in the field. There are lots of areas where measuring light spectrum and irradiance outside a laboratory is ...
Morph-based resistance against Schistocephalus solidus in three-spined sticklebacks (Gasterosteus aculeatus) selected under different infection- and predation regimes
(The University of Bergen, 2013-06-07)
The morphology of a host may have an effect on its resistance against parasites. Two geographically separated and morphologically divergent populations of three-spined sticklebacks (Gasterosteus aculeatus, Linnaeus, 1758) ...
Ecology of testate amoebae (Protista) in south-central Alaska peatlands: building transfer-function models for palaeoenvironmental studies
Testate amoebae are valuable indicators of peatland hydrology and have been used in many palaeoclimatic studies in peatlands. Because the species' ecological optima may vary around the globe, the development of transfer ...
A bio-economic analysis of harvest control rules for the Northeast Arctic cod fishery
Harvest control rules (HCRs) have been implemented for many fisheries worldwide. However, in most instances, those HCRs are not based on the explicit feedbacks between stock properties and economic considerations. This ...
Simulation of viscous instabilities in miscible and immiscible displacement
(The University of Bergen, 2008-06-09)
This study includes modeling of viscous instabilities at both miscible and immiscible displacement. Oil recovery of heavy oil leads to unstable displacement for adverse mobility ratio for both miscible and immiscible ...
Vannbasert eor i oppsprukne bergarter - økt oljeutvinning ved kjemikalietilsetning i injeksjonsvannet
(The University of Bergen, 2010-06-01)
En stor del av verdens hydrokarbonreserver finnes i karbonater. Karbonatreservoarer er komplekse fordi reservoarbergarten ofte er sprø og sprekker lett. Mineralsammensetningen av karbonater gjør poreoverflaten mer tilbøyelig ...
