Constraints on Strong Phase Transitions in Neutron Stars
(Peer reviewed; Journal article, 2023)We study current bounds on strong first-order phase transitions (PTs) along the equation of state (EOS) of dense strongly interacting matter in neutron stars, under the simplifying assumption that on either side of the PT, ... -
Mimicking orchids lure bees from afar with exaggerated ultraviolet signals
(Peer reviewed; Journal article, 2023-01)Flowers have many traits to appeal to pollinators, including ultraviolet (UV) absorbing markings, which are well-known for attracting bees at close proximity (e.g., <1 m). While striking UV signals have been thought to ... -
Statistical analysis of locally parameterized shapes
(Peer reviewed; Journal article, 2022)In statistical shape analysis, the establishment of correspondence and defining shape representation are crucial steps for hypothesis testing to detect and explain local dissimilarities between two groups of objects. Most ... -
A modelling study of environmental fate and effects of oil leakage from abandoned wells
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-06-15)Potential environmental consequences of oil leakages are taken into consideration in the ongoing development of plug and abandonment (P&A) activities on the Norwegian Continental Shelf (NCS). The P&A on the NCS has been ... -
Anaerobic treatment of industrial wastewater with a pilot scale UASB reactor
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-07-13)The focus of this study was to investigate the performance of anaerobic treatment with a UASB pilot reactor for removal of COD in industrial wastewater at ambient temperatures at Grødaland wastewater treatment plant in ... -
Preparation and Reactions of Straind gem-Dibromocyclopropanes
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06-29)Two main objectives drove the present effort. First and foremost, reactions of strained gem-dibromocyclopropanes with MeLi were to be investigated as a continuation of research done by Lars Skattebøl. Secondly, the overcoming ... -
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 ... -
Regiospesific synthesis of dimethylphenanthrenes
(Peer reviewed; Journal article, 2017-05)The dimethylated phenanthrenes 2,3-dimethylphenanthrene (4a), 2,7-dimethylphenanthrene (4b), 2,6-dimethylphenanthrene (4c) and 1,7-dimethylphenanthrene (4d) have been prepared in gram-quantities by a short sequence of ... -
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 ... -
Optimization of acid catalyzed transesterification of jatropha and rapeseed oil with 1-butanol
(Peer reviewed; Journal article, 2014-08)The acid catalyzed transesterification of rapeseed and jatropha oil with 1-butanol was studied by varying temperature, reaction time, butanol/triglyceride ratio and the amount of sulfuric acid. A full factorial design ... -
Enantioselective synthesis of (-)-(1R,2R)-1,2-dihydrochrysene-1,2-diol
(Peer reviewed; Journal article, 2014)A general chiral building block containing the 1R,2R-trans-diol moiety was constructed utilizing the stereoselective Shi-epoxidation reaction on a tetralone scaffold assembled by a Negishi cross-coupling on N,N-diethylbenzamide. ... -
Biomarker responses and accumulation of polycyclic aromatic hydrocarbons in Mytilus trossulus and Gammarus oceanicus during exposure to crude oil
(Peer reviewed; Journal article, 2020)In the brackish water Baltic Sea, oil pollution is an ever-present and significant environmental threat mainly due to the continuously increasing volume of oil transport in the area. In this study, effects of exposure to ... -
Investigation into method to raise the deposition point of kinetic hydrate inhibitor polymers
(Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-12-14)This paper decribes the the possibility to increase the deposition point of a kinetic hydrate inhibitor by adding additives such as non-ionic, anionic and cationic polymers. -
Hyper-Kähler fourfolds and Kummer surfaces
(Journal article; Peer reviewed, 2017-09)We show that a Hilbert scheme of conics on a Fano fourfold double cover of PP2xP2 ramified along a divisor of bidegree (2,2) admits a ℙ 1‐fibration with base being a hyper‐Kähler fourfold. We investigate the geometry of ... -
Chiral and deconfinement transitions in a magnetic background using the functional renormalization group with the Polyakov loop
(Journal article; Peer reviewed, 2014-04)We use the Polyakov loop coupled quark-meson model to approximate low energy QCD and present results for the chiral and deconfinement transitions in the presence of a constant magnetic background B at finite temperature T ... -
Sensitivity analysis of a pathway with respect to fast and small temperature change
(Journal article; Peer reviewed, 2019)Temperature affects all enzymes simultaneously in a metabolic system. The enzyme concentration in a biochemical system can be considered as invariant under fast and small temperature change. Therefore, the total sensitivity ... -
Microwave-Assisted One-Pot Synthesis of Novel Polyarylpyrrole Derivatives of Expected Anticancer Activity
(Journal article, 2017)An efficient synthesis of Novel pyrrolederivatives was achieved via solventless reaction of chalcones 1(a-e) with different aldehydes 2(a-e) and ammonium acetate in the presence of sodium cyanide in one-pot under microwave ... -
Computational evaluation of different arrangements for the circadian clock in Arabidopsis thaliana.
(Masteroppgave/UIS-TN-IKBM/2019;, Master thesis, 2019-08)The circadian clock is an endogenous timekeeper that enables individuals to predict and adjust to their environment's regular differences between light and dark and high and low temperatures. This biological timing mechanism ... -
