Magnetic and Thermodynamic Properties of Layered and Thin Film Superconductors
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:63, Doctoral thesis, 2004)A large variety of measurements, most of magnetic nature, performed on single crystals of high temperature superconductors and thin films of lead, are presented. Furthermore, numerical calculations of the magnetic properties ... -
Nanoparticles in dilute solution: Theory and experiments
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:49, Doctoral thesis, 2004)My thesis focuses on nanoparticles in dilute solution. The nanoparticles that interest us the most are biopolymers (DNA, RNA, proteins, and polysaccharides). Biopolymers are molecules of biological origin. Biopolymers are ... -
Chitosan-mediated DNA condensation as a basis for gene delivery: Influence of polyelectrolyte molecular parameters on the condensation behaviour
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:133, Doctoral thesis, 2004)Polycation mediated gene delivery has emerged as a promising alternative to the use of viral vectors for gene therapy. Although yielding significantly lower transfection efficiency than viral vectors, the use of polycations ... -
Polyelectrolyte complexes and multilayers assembled from biopolymers : electrostatically driven formation of mesoscale structures
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:127, Doctoral thesis, 2004)Oppositely charged polyelectrolytes interact spontaneously upon mixing. This interaction can be exploited to form polyelectrolyte complexes and polyelectrolyte multilayers. In the latter case the interaction takes place ... -
Energy spectra and scaling relations in numerical turbulence with laboratory and astrophysical applications
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:163, Doctoral thesis, 2004)In this work we have focused on the statistical properties of turbulence. This has been done in two different settings; one with neutral gas (the first four papers) and the other with ionized gas (the last four papers). ... -
Spectral actinic flux in the lower troposphere: measurement and 1-D simulations for cloudless, broken cloud and overcast situations
(Journal article; Peer reviewed, 2005)In September 2002, the first INSPECTRO campaign to study the influence of clouds on the spectral actinic flux in the lower troposphere was carried out in East Anglia, England. Measurements of the actinic flux, the irradiance ... -
Some aspects of cavity quantum electrodynamics
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:77, Doctoral thesis, 2005)We have in this thesis looked at two very different problems related to quantum optics. In Part I we have studied the Jaynes-Cummings model with cavity damping and a thermal background. To give an introduction to the field ... -
Psychophysics of reading and illumination needs during reading in visually impaired subjects with age-related macular degeneration
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:32, Doctoral thesis, 2005)The primary aim of this study was to contribute to a better understanding of how we can optimize reading conditions for subjects with age-related macular degeneration (AMD). In order to achieve this goal, we have developed ... -
Critical properties of effective gauge theories for novel quantum fluids
