The influence of inorganic nitrogen compounds on gene expression profiles in neurospora crassa: a microarray analysis
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-02)The purpose of this study was to investigate expression profiles of Neurospora crassa genes related to the nitrogen metabolism. Two nitrogen sources (ammonium and nitrate) and responses to light were meant to alter ... -
The influence of nitrogen on compounds and quality of Arabidopsis thaliana and tomato
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Part A: The influence of nitrogen on compounds and quality of Arabidopsis thaliana Flavonoids are secondary metabolites in plants that are thought to have beneficial effects on human health, as well as importance for ... -
The organization of controller motifs leading to robust plant iron homeostasis
(Journal article; Peer reviewed, 2016-01)Iron is an essential element needed by all organisms for growth and development. Because iron becomes toxic at higher concentrations iron is under homeostatic control. Plants face also the problem that iron in the soil is ... -
The use of caged mussels for monitoring produced water discharges: the Norwegian Water Column Monitoring Program
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-12-14)Offshore activities, especially productions platforms might be responsible to adverse biological effect on local marine organisms. In order to assess this impact a water column monitoring program was designed and performed ... -
The use of Palladium on Magnetic Support as Catalyst for Suzuki-Miyaura Cross-Coupling Reactions
(Journal article; Peer reviewed, 2017-01-23)The development of new solid supports for palladium has received a lot of interest lately. These catalysts have been tested in a range of cross-coupling reactions, such as Suzuki–Miyaura, Mizoroki-Heck, and Sonogashira ... -
Thermal properties of geopolymer materials
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06-15)Ordinary Portland cement (OPC) is traditionally the most common binder in concrete manufacturing and is widely used in the petroleum industry, yet its mechanical properties have some shortcomings and its production has ... -
