(Master thesis, 2017-06-09)Mitochondria are highly dynamic organelles, with an essential role in proper cell function. Increasing evidence points towards a key role of mitochondria and its bioenergetic state for pathogenesis of neurodegenerative ... -
Analysis of corrosion resistance property of cold bended 316L and 6Mo stainless steel pipes
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-06-16)The variation in mechanical properties after cold deformation (bending) of pipes is one of the interesting subjects in material science. One major quality the material should possess is high corrosion resistance after ... -
Anomalous electrodynamics of neutral pion matter in strong magnetic fields
(Journal article; Peer reviewed, 2017-03)The ground state of quantum chromodynamics in sufficiently strong external magnetic fields and at moderate baryon chemical potential is a chiral soliton lattice (CSL) of neutral pions [1]. We investigate the interplay ... -
Antibacterial effect of chitosan in relation to active food packaging
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)Food safety has a high priority in the food industry. In order to be able to give the consumers safe products, the producers continuously work with methods to inhibit growth of bacteria in the foods during storage. Recently, ... -
Aspects of X-Ray Diffraction Using Mathematica
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06-15)A specialised Mathematica package has been launched, which is intended to become a valuable tool in our line of work. Old and new code has been compiled to a single, organised and flexible package, featuring a neat ... -
Base excision repair of N4,5-dimethylcytosine in DNA
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-07-13)5-Methylcytosine (m5C) replaces cytosine (C) in DNA in prokaryotic and eukaryotic cells to execute a number of important cellular functions, but damage to m5C have received little attention. For instance, almost no studies ... -
Basis invariant measure of CP-violation and renormalization.
(Journal article; Peer reviewed, 2015-08)We analyze, in the context of a simple toy model, for which renormalization schemes the CP-properties of bare Lagrangian and its finite part coincide. We show that this is the case for the minimal subtraction and on-shell ... -
