Thermal treatment of drill cuttings
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06-30)Increased environmental stringency, and focus on cost efficiency, drives the oil & gas industry towards new and better solutions. Members of OSPAR have to follow strict discharge requirements for oil contaminated drill ... -
Total synthesis of tubastrine and 3-dehydroxy tubastrine by microwave-assisted cross-coupling reactions
(Journal article, 2015-10)The first syntheses of tubastrine and 3-dehydroxy tubastrine are described. The target compounds were prepared in four consecutive steps from commercially available starting materials. The central scaffold was formed by a ... -
Tracing of PAH concentration in drill cuttings through the TCC process.
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-07-14)Strict regulations for polycyclic aromatic hydrocarbons (PAH) concentrations in discharged water prompts the oil and gas industry to improve treatment for produced water and drilling fluids which are the main sources of ... -
Treating Drill Cuttings with Susceptors in a Single-mode Cavity Microwave
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-29)The aim of the thesis was to evaluate the use of single-mode applicator in combination with susceptor technology for treatment of oil contaminated drill cuttings. Single-mode applicators allow samples to be exposed to high ... -
Tumor Interstitial Fluid Pressure Distribution – Analytical and Numerical Study
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017)Cancer is one of the deadliest diseases in the world and although huge research efforts have been applied to improve survival rates, there are still great challenges in treatment of the disease. Many factors contribute in ... -

Tuning the thermoresponsive properties of Hyperbranched Poly(ester amide)s based on diisopropanolamine and cyclic dicarboxylic anhydrides
(Journal article; Peer reviewed, 2011-08)A range of water-soluble hyperbranched poly(ester amide)s has been synthesized with a view to studying their thermoresponsive behavior in water. Poly(ester amide)s with lower critical solution temperature (LCST) values ... -
Type III and II universal spacetimes
(Journal article; Peer reviewed, 2015)We briefly summarize our recent results on universal spacetimes. We show that universal spacetimes are necessarily CSI, i.e. for these spacetimes, all curvature invariants constructed from the Riemann tensor and its ... -
Type N universal spacetimes
(Journal article; Peer reviewed, 2015)Universal spacetimes are vacuum solutions to all theories of gravity with the Lagrangian L [...]. Well known examples of universal spacetimes are plane waves which are of the Weyl type N. Here, we discuss recent results ... -
Ultrasound-assisted synthesis of novel 1,2,3-triazoles coupled diaryl sulfone moieties by the CuAAC reaction, and biological evaluation of them as antioxidant and antimicrobial agents
(Peer reviewed; Journal article, 2014-09)A series of 1,2,3-triazoles coupled diaryl sulfone containing compounds were synthesized by the copper-catalyzed azide-alkyne 1,3-dipolar cycloaddition (CuAAC) reaction in benign solvents under ultrasound irradiation. In ... -
The use of flotation technology in produced water treatment in the oil & gas industry
(Masteroppgave/UIS-TN-IMN/2011;, Master thesis, 2011)Produced water quality has become an increasingly large area of concern for the oil production industry. A great deal of scientific research has been carried out to determine the consequences of long term exposure of ... -
Uttesting og validering av metoder for derivatisering og analyse ved hjelp av GC-EI/NCI-MS av tyrosin og nitrotyrosin.
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06-12)3-Nitrotyrosin (3-NT) kan være en mulig biomarkør for å måle nitro-oksidativt stress, og det er derfor av interesse å etablere en metode for å måle konsentrasjonen i humant plasma. 3-NT blir produsert in vivo ved nitrering ... -
Validation of a capillary pressure correlation for dynamic wettability alteration
