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 ... -
Environmental harm assessment of a wastewater discharge from Hammerfest LNG: A study with biomarkers in mussels (Mytilus sp.) and Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2013-04)Biologically treated wastewater (WW) from the Hammerfest LNG (liquefied natural gas) plant is discharged to the sea. A study using biomarkers in mussels and Atlantic cod was performed to examine whether this discharge meets ... -
Metabolic phenotype of leukemia cells as a determinant factor for the response to metformin in different glucose conditions
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-15)Cancer cells are known to have highly dysregulated metabolic pathways and altered mitochondria which governs their limited capability of adaptation to nutritional growth conditions. Metabolic flexibility can be reduced by ... -
Evaluation of Using Coagulants for Treatment of Highly Viscous Slop Water Containing Xanthan Gum
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-13)Exploration and development drilling activities in offshore Oil and Gas industry generates waste streams, which slop water are among the significant wastes. Slop water is formed when wastewater originating from multiple ... -
Effect on solids separation from wastewater with varying aeration and mixing conditions
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06-15)The main objective of this review was to analyze the effect on the separation of solids from wastewater with different conditions of aeration and mixing in order to compare their efficiency when both processes act ... -
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 ... -
The Effects of Metformin on the Metabolism of Colorectal Cancer Cell Lines SW948 and SW1116
(Masteroppgave/UIS-TN-IKBM/2018;, Master thesis, 2018-06)Metformin is an anti-diabetes drug with cancer preventative capabilities, which is widely studied to help develop treatment to aid future colorectal cancer prevention and recovery. This studies aims were to assess the ... -
Environmental impacts of produced water and drilling waste discharges from the Norwegian offshore petroleum industry
(Journal article; Peer reviewed, 2013-09)Operational discharges of produced water and drill cuttings from offshore oil and gas platforms are a continuous source of contaminants to continental shelf ecosystems. This paper reviews recent research on the biological ... -
Tumor Interstitial Fluid Pressure Distribution – Analytical and Numerical Study
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-11-27)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 ... -
A new species of Pollenia Robineau-Desvoidy, 1830 from Jordan (Diptera: Calliphoridae: Polleniinae)
(Journal article; Peer reviewed, 2016-01)A new species, Pollenia bartaki sp. nov., assigned to the Pollenia rudis species-group in Pollenia Robineau-Desvoidy, 1830, is described on the basis of a single male specimen captured in Jordan. Its strongly curved surstylus ... -
Determination of porin channel activity and evolution of targeting signals in plant peroxisomes
(University of Stavanger, Norway;, Doctoral thesis, 2013)Peroxisomes are eukaryotic organelles traditionally known for their roles in fatty acid metabolism and generation and removal of hydrogen peroxide. Several new functions are being ascribed to these organelles with the help ... -
DNA base excision repair : mutation induction and novel functions
(University of Stavanger, Norway;, Doctoral thesis, 2015-06)DNA is susceptible to chemical modifications corrupting its cellular information processing function, necessitating correction of such modifications. Cells are formed mostly by water – giving rise to hydrolytic reactions ... -
Simulations of Cold Electroweak Baryogenesis: hypercharge U(1) and the creation of helical magnetic fields
(Journal article; Peer reviewed, 2017-06)We perform numerical simulations of Cold Electroweak Baryogenesis, including for the first time in the Bosonic sector the full electroweak gauge group SU(2) × U(1) and CP-violation. We find that the maximum generated baryon ... -
Dimensional reduction of the Standard Model coupled to a new singlet scalar field
(Journal article; Peer reviewed, 2017)We derive an effective dimensionally reduced theory for the Standard Model augmented by a real singlet scalar. We treat the singlet as a superheavy field and integrate it out, leaving an effective theory involving only the ... -
Simulations of Cold Electroweak Baryogenesis: finding the optimal quench time
(Journal article; Peer reviewed, 2017-07)We revisit the numerical computation of the baryon asymmetry from Cold Electroweak Baryogenesis given the physical Higgs mass. We investigate the dependence of the asymmetry on the speed at which electroweak symmetry ... -
On high-order perturbative calculations at finite density
(Journal article; Peer reviewed, 2017-02)We discuss the prospects of performing high-order perturbative calculations in systems characterized by a vanishing temperature but finite density. In particular, we show that the determination of generic Feynman integrals ... -
Simulations of "tunnelling of the 3rd kind"
(Journal article; Peer reviewed, 2017-07)We consider the phenomenon of “tunnelling of the 3rd kind” [1], whereby a magnetic field may traverse a classically impenetrable barrier by pair creation of unimpeded quantum fermions. These propagate through the barrier ... -
