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

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 ... -
Biochemical and molecular analysis of LC-PUFA biosynthesis in the microalga Nannochloropsis
(Masteroppgave/UIS-TN-IMN/2013;, Master thesis, 2013-06-17)The present research project comprised both basic research and biotechnology and focused on investigating the role of peroxisomes in lipid metabolism in the lipid-rich microalgae, Phaeodactylum and Nannochloropsis, and on ... -
Biodegradation and chemical characterization of petroleum diesel hydrocarbons in seawater at low temperatures
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010-06)Petroleum hydrocarbons are a major source of marine contamination. Biodegradation, which is fundamental for the natural attenuation of these hydrocarbons in nature, involves mineralization or transformation of organic ... -
Biodiesel by acid-catalyzed transesterification with butanol
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2012-07-11)Jatropha oil and Rapeseed oil was transesterified with n-butanol by the use of H2SO4. Before conducting the experiments a review of the effect of alcohol type was preformed. Alcohols from methanol to butanol, branched and ... -
Biogas potential of high strength municipal wastewater treatment in laboratory scale up-flow anaerobic slugde blanket (UASB) reactors
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06-15)The main focus of this study is investigating the effectiveness of anaerobic treatment of municipal wastewater for converting organic matter to methane production in anaerobic granular sludge reactors. In-house designed ... -
Biogas potential of municipal sludge, industrial waste, livestock manure, and preliminary study of Røysland farm biogas plant
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)Anaerobic digestion involves a series of metabolic reactions in which complex substrates in the feed are reduced to a mixture having as main products methane and carbon dioxide. Biochemical methane potential (BMP) of ... -
Biological effects in fish and mussels of oil spill pollution in northern areas
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)The oil and gas activities in the northern region have showed an increase over the last years. This year a new field, Skrugard, was discovered in the Barents Sea and the two parliaments in Norway and Russia confirmed the ... -
Biological treatment of industrial wastewater for biogas production
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Anaerobic biodegradation is a method of degradation that converts approximately 90% of the available chemical energy (in the form of organic material), into gas methane. Apart from the economic value of the methane gas ... -
