Protein phosphatase 2A and cryptochrome in plant development
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Protein phosphatase 2A (PP2A) is a serine/threonine-specific phosphatase that regulates diverse signaling events in plants. PP2A consist of three subunits, a catalytic subunit (C), a scaffolding subunit (A), and a regulatory ... -
Protein phosphatase 4 recombinant protein – transformation of bacteria and Arabidopsis thaliana
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06)Protein phosphatase 4 (PP4) is well conserved in eukaryote organisms. The protein has been studied in yeast and mammalian cells, but little is known about PP4 in plants. The function of PP4 in plants is unknown and ... -
Quality of Norwegian cucumbers: effect of greenhouse praxis on taste and taste related constituents, and GC-FID analysis on content of fatty acids and aldehydes
(Master thesis, 2014-07-14)Earlier studies have shown that sugars (SSC), salts (EC) and the relationships between sugars/salts and sugars/acids (TTA- total titratable acids) may impact taste in cucumber. In this study, the impacts of ... -
Quantum correction to inflation and curvature perturbation
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06)Inflation is a sudden and near exponential expansion of space in early universe. Infla- tion solved flatness problem, horizon problem and monopole problem that persisted in standard big bang cosmology. It was not only useful ... -
Rapid detection of microorganisms in the dairy value chain by MALDI-TOF MS
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06)Recently, Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) has developed as vigorous method for the identification of microorganisms in the clinical sector. MALDI-TOF MS is able ... -
Recombinant expression of transglutaminase from Atlantic cod in E. coli
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Transglutaminases (TGs) are a family of enzymes that catalyzes cross linking of proteins by forming covalent bonds between lysine residues and glutamine residues in different polypeptides. Cross-linking reactions are ... -
Recovery of oil spills by dispersants in marine arctic regions
(Masteroppgave/UIS-TN-IMN/2010;, Master thesis, 2010)The initial appearance of dispersants was 1960s and 1970s; oil spill dispersants have been the topic of significant research, testing, and debate. In spite of published reports about dispersant toxicity and effectiveness ... -
Reduction of scaling in biological treatment of industrial waste water at SART
(Master thesis, 2012)Scale formation is one of serious problems for oil industry and water treatment. Thanks to well-developed technologies today these is a wide spectrum of solutions, consisting of chemical inhibitors, evaporators and reverse ... -
Regiospecific synthesis of disubstituted phenanthrenes
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-06-16)As the Norwegian oil fields mature, the wells produce more water. This produced water containing a diverse mixture of dissolved PAHs is eventually released to the environment. A major part of these discharges are alkylated ... -
Removal of MBBR Biofilm Solids by Salsnes Filter Fine Mesh Sieves
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Biological wastewater treatment is often used in conjunction with primary treatment to reduce the constituents in wastewater. It is normally necessary to separate the biomass from the treated wastewater in order to meet ... -
Retention and biological uptake of phosphorous in the Leikvollbekken constructed wetland
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-15)Phosphorous is the limiting nutrient for primary production in freshwater systems and excessively applied as inorganic fertilizer in agriculture. Elevated phosphorous concentrations in recipients can cause eutrophication ... -

(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Temaet for masteroppgaven er ``Elementer i dynamisk teori for røntgendiffraksjon''. Oppgaven har utgangspunkt i C. G. Darwins to artikler fra 1914 og hatt som mål å gå igjennom disse på en pedagogisk måte. Det er lagt vekt ... -
Røntgendiffraksjon : Darwins dynamiske teori for transmisjonsgeometri
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)En sentral teori innen fagfeltet røntgendiffraksjon, har tradisjonelt vært Ewald-von Laue teorien. En annen, mindre nyttet teori er den Darwin publiserte i 1914. Denne oppgaven tar først utgangspunkt i den kinematiske ... -
Screening for biosurfactant-producing bacteria for crude oil degradation, under cool and saline conditions
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06)Using three sources with different hydrocarbon exposure histories—bacteria grown from Arctic seawater (Arctic), and bacteria from an offshore wastewater treatment system from both the bioreactor (BR) and settling chamber ... -
Search for new technologies that can give environmental benefits to the oil industry, subsea waterflooding
