Investigation of co-digestion of food waste and primary sludge at SNJ-wastewater treatment
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Anaerobic co-digestion of different organic waste streams, has proven to be a viable solution for sustainable management of organic fraction of waste, with increased everyday application. Besides the environmentally sound ... -
Investigation of corrosion resistance property of cold deformed (bended) duplex and super duplex stainless steel tubes
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-06-16)Cold deformation (bending) of stainless steel tubes is one of the efficient and cost effective methods to gain the required shapes of the tube that can be useful for different practical applications. Different mechanical ... -
Investigation of DNA-free genome editing in Arabidopsis thaliana with pre-assembled CRISPR-Cas9 ribonucleoproteins and transcripts.
(Master thesis, 2017-06-15)Programmable sequence-specific nucleases (SSNs) produces double stranded breaks (DSBs) in the genome in a site-specific manner. The following repair through endogenous repair systems allows targeted genome editing, which ... -
Investigation of Ring-Openings of Some gem-Dichlorocyclopropanes
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-29)The main purpose of this thesis was to study ring-openings of gem-dichlorocyclopropanes under basic conditions and the formation of acetylenic acetals. Therefore, several 2-alkoxy-1,1-dichlorocyclopropanes were synthesized ... -
Investigation of the Physiological Function of Protein Phosphatase 4 (PP4) in Arabidopsis thaliana
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06-14)Protein Phosphatase 4 (PP4), a member of serine/threonine-specific phospho-protein phosphatases (PPP) family, is remarkably well conserved across eukaryotes. PP4 has been studied mainly in yeast and mammalian cells, and ... -
