Enhanced Oil Recovery by Combined Low Salinity Water and Polymer Flooding
(The University of Bergen, 2014-06-19)
World energy demand is continuously increasing as the developed and developing countries consume more energy to keep their growing industries running. Significant portion of the energy demand is supplied by fossil energies, ...
Totalkvikksølv og metylkvikksølv i filet og lever av brosme fiska i Boknafjorden, samanlikna med Hardangerfjorden og Lofoten
(The University of Bergen, 2014-11-20)
Det har i lang tid vore kjend at Hardangerfjorden er forureina, spesielt innerst i fjorden. Tidlegare masteroppgåver som er blitt gjort ved NIFES har funne kvikksølvkonsentrasjonar i brosme (Brosme brosme) frå Hardangerfjorden ...
Forsøk på syntese av imidazol-2-yliden baserte sølvkomplekser med hydrofile 4-(5)-sidekjeder
(The University of Bergen, 2010-05-31)
Sølvets bakteriedrepende egenskaper har vært kjent siden antikken og sølv har vært utnyttet som sårbehandler helt inn i moderne tider. Utviklingen av sølvpreparater har vært lang og inkluderer sølvobjekter og salter til ...
Towards a Synthesis of the Marine Alkaloid Naamidine B
(The University of Bergen, 2014-09-15)
Technetium-99 (99Tc) in the North and Nordic Seas – the present status (2010) and a compilation of the Institute of Marine Research’s monitoring data (2003-2009)
(The University of Bergen, 2011-04-26)
Technetium-99 (99Tc) is an anthropogenic, pure β-emitting (Emax = 292 keV) radionuclide with a half-life of 2.13 · 10^5 years. It is present in the marine environment primarily due to discharges from nuclear fuel reprocessing ...
Enzymes for Enhanced Oil Recovery (EOR)
(The University of Bergen, 2011-06-30)
Primary oil recovery by reservoir pressure depletion and secondary oil recovery by waterflooding usually result in poor displacement efficiency. As a consequence there is always some trapped oil remaining in oil reservoirs. ...
Cyclopentane Hydrate for Hydrate Wetting Studies
(The University of Bergen, 2013-06-03)
Abstract Gas hydrates are often found in the systems for production of petroleum, natural gas and water systems, which is highly undesirable. In some systems the hydrates can form rapidly into large plugs and agglomerate ...
Quinolone-DNA interactions. Interactions and association between Ofloxacin and a DNA-oligomer studied by NMR methods
(The University of Bergen, 2003)
The first part of this thesis examines Ofloxacin (Oflo), a second-generation quinolone, by applying 1D 1H NMR. Molecular dynamics, stacking conditions and the self-diffusion constant were investigated. No certain ...
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 ...
Development of a solid phase extraction method for evaluating the production of classic and nonclassic eicosanoids in human and fish cells using liquid chromatography tandem mass spectrometry
(The University of Bergen and National Institute of Nutrition and Seafood Research (NIFES), 2014-03-14)
Eicosanoids are the major metabolites of fatty acids and they are correlated with many kinds of diseases such as Alzheimer's, cancer and cardiovascular diseases. Usually, most of the eicosanoids derived from omega-6 fatty ...
