Viscous cosmology - Bulk viscosity in the cosmological context
(Master thesis, 2015)The main objective of this thesis has been to estimate the present value of the bulk viscosity of the cosmic fluid. The following list contains a summary of the main results found in the present work: -The bulk viscosity ... -
Modeling the propagation of streamers in liquids - The Townsend-Meek criterion and a novel model for photoionization
(Master thesis, 2015)Conducting channels forms when a dielectric liquid is subjected to high electric stress. These channels are know as streamers, and if allowed the time to form and propagate, they can lead to an electrical breakdown. Sintef ... -
Numerical Investigations on Nanobubble Stability
(Master thesis, 2015)This thesis discusses the stability and lifetime of bulk and surface nanobubbles. Two numerical models are presented which have been developed in order to investigate aspects of the dynamic equilibrium mechanism using ... -
Quantitative Comparison of PET/MR and PET/CT for Imaging of Lymphoma Patients
(Master thesis, 2015)Positron emission tomography/computed tomography (PET/CT), a multimodality imaging tool, is today the golden standard in diagnosis, staging and response monitoring of lymphoma patients, while it is investigated if positron ... -
Thermal remixing of phase-separated states in two-component bosonic condensates
(Journal article; Peer reviewed, 2015)Weconsider a two-component interacting bosonic condensate with dominating intra-species repulsive density–density interactions.Westudy the phase diagram of the system at finite temperature with rotation, using large-scale ... -
The role of oligosaccharide decorations in mucin interaction capacities : assessment by high resolution force probes
(Doctoral thesis at NTNU;2015:32, Doctoral thesis, 2015)Mucins are large proteins glycosylated with oligosaccharide groups. They are secreted from epithelial cells or embedded in the apical side of the epithelial cell and promote cell survival in different ways. Mucins also ... -
TEM Characterization of LaFeO3Thin Films on SrTiO3 (111) Substrates
(Master thesis, 2015)In this thesis transmission electron microscopy (TEM) was used to study the atomic structure of LaFeO3 (LFO) thin films grown on (111) oriented SrTiO3 (STO) substrates by pulsed laser deposition. To prepare TEM samples ... -
Development of a compact radiation monitor for space application
(Master thesis, 2015)In this work a compact radiation monitor prototype has been developed. The present device and its technology will directly contribute towards the CPT-SCOPE project, a Norwegian-German student project developing a radiation ... -
Microfluidic Fabrication of Mineralized Alginate Hydrogel Fibers
(Master thesis, 2015)Alginates are a family of naturally occurring polysaccharides that form gels in the presence of Ca2+-ions at physiological conditions. Calcium phosphate mineralized alginates have previously been investigated as a synthetic ... -
Electrical Excitation of Water Drops in Oil
(Master thesis, 2015)Water drops in oil are excited by the use of electric fields. This thesis looks at the behavior of water drops subjected to different fields. These fields vary in shape and strength. The motivation behind is separation of ... -
Structural modifications and electron beam damage in aluminium alloy precipitate θ'-Al2Cu
(Journal article, 2015)The –AlCu phase in an Al–4Zn–2Cu–1Mg–0.7Si (wt.%) alloy was investigated by means of scanning transmission electron microscopy. With our specific alloy composition, the phase is often formed with stacking faults on and ... -
VMAT for small cell lung cancer
(Master thesis, 2015)Limited stage small cell lung cancer (SCLC-LS) is an aggressive cancer form affecting a relatively small group of patients. The prognosis for these patients is poor, and those who are treated with radiotherapy often develop ... -
Tumor Dosimetry in a Phase I Study of Lu(177)-DOTA-HH1 (Betalutin) - How hard does the magic bullet strike?
(Master thesis, 2015)Introduction: Antibody-radionuclide-conjugate therapy using the monoclonal antibody agent 177 Lu-DOTA-HH1 (BetalutinTM ) developed by Nordic Nanovector, is a novel treatment of Non-Hodgkin s Lymphoma. A Phase I/II study ... -
The breast cancer-associated glycoforms of MUC1, MUC1-Tn and sialyl-Tn, are expressed in COSMC wild-type cells and bind the C-type lectin MGL
(Journal article, 2015)Aberrant glycosylation occurs in the majority of human cancers and changes in mucin-type O-glycosylation are key events that play a role in the induction of invasion and metastases. These changes generate novel cancer-specific ... -
Controlling the switching field in nanomagnets by means of domain-engineered antiferromagnets
(Journal article, 2015)Using soft x-ray spectromicroscopy, we investigate the magnetic domain structure in embedded nanomagnets defined in La0.7Sr0.3MnO3 thin films and LaFeO3/La0.7Sr0.3MnO3 bilayers. We find that shape-controlled antiferromagnetic ... -
Energy Landscape of Alginate-Epimerase Interactions Assessed by Optical Tweezers and Atomic Force Microscopy
(Journal article, 2015)Mannuronan C-5 epimerases are a family of enzymes that catalyze epimerization of alginates at the polymer level. This group of enzymes thus enables the tailor-making of various alginate residue sequences to attain various ... -
