Faulting and the relationship to fluid migration and shallow gas accumulation in the Hammerfest Basin, SW Barents Sea
(Master thesis; Mastergradsoppgave, 2015-05-01)This thesis has focused its efforts to identify and map faults and their relationships to shallow gas accumulations and fluid flow features. The area of this investigation lies in the hydrocarbon-prone Hammerfest Basin in the southwestern Barents Sea, above the Base Cretaceous. Nine 3D seismic datasets were used in this study, aiming to improve the knowledge of the timing of the tectonic activity ... -
Asynchronous response of marine-terminating outlet glaciers during deglaciation of the Fennoscandian Ice Sheet
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-03-31)Recent studies have highlighted the dynamic behavior of marine-terminating outlet glaciers over decadal time scales, linked to both atmospheric and oceanic warming. This helps explain episodes of nearly synchronous fl ow acceleration, thinning, and retreat, but nonclimatic factors such as changes in fjord width and depth, can also induce rapid recession. There is support for these topographic ... -
Multi-radar observations of polar mesosphere summer echoes during the PHOCUS campaign on 20-22 July 2011
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-06-27)During the PHOCUS rocket campaign, on 20-22 July 2011, the observations of polar mesosphere summer echoes (PMSE) were made by three mesosphere-stratosphere-troposphere radars, operating at about 50 MHz. One radar, ESRAD is located at Esrange in Sweden, where the rocket was launched, two other radars, MAARSY and MORRO, are located 250 km north-west and 200 km north of ESRAD, respectively, on the other ... -
On the Synthesis of Breitfussins. Toward the total synthesis of Breitfussin A and analogues
(Master thesis; Mastergradsoppgave, 2014-05)The Breitfussins are a series of closely related heterocyclic compounds originated from the marine organism Thelia Breitfussi. The core is a 5(indol-3-yl)-2-(pyrrol-2-yl)oxazole, which has not been observed prior to its isolation in 2007. The divergence of the Breitfussins lies in the halogenation pattern and methoxy substitution. Breitfussin A is of synthetic interest because of its novel structural ... -
The nature of the gas-hydrate/free gas transition zone at the base of the hydrate-stability zone from high-resolution 3D seismic data
(Master thesis; Mastergradsoppgave, 2015-01-26)Geophysical evidence of a prominent BSR at Vestnesa Ridge and north to the northern flank of the Storegga slide escarpment infer that gas hydrates are ubiquitous within these regions. A wide range of fluid flow structures have previously been discovered from these regions, as well as gas seepage activity from pockmarks on the eastern segment of Vestnesa Ridge. This paper focuses on high-resolution ... -
Forskningsprosessen i kjemi – Utvikling og utprøving av et undervisningsopplegg i kjemi 2
(Master thesis; Mastergradsoppgave, 2014-05-31)Læreplanen i kjemi legger i stor grad opp til praktisk arbeid i faget. Forskning tyder på at skoleelever sliter med å lære av elevforsøk, særlig strever elevene med å knytte den praktiske delen av øvelsen opp mot fagteori. Denne oppgaven omhandler et undervisningsopplegg i kjemi 2, kalt syntese og analyse av dibenzalaceton. Målet med opplegget var å illustrere en helhetlig forskningsprosess for ... -
MD simulations reveal how synthetic antimicrobial peptides interact with membrane models
(Master thesis; Mastergradsoppgave, 2014-12-17)Since the discovery of antibiotics the extensive use in health care and agriculture has led to the development of resistant bacterial strains. Antimicrobial peptides (AMPs) exists in nature where they are believed to play an important role in the innate immune system in vertebrates. Due to their antibacterial properties and apparent ability to elicit very low bacterial resistance, researchers have ... -
Target characterization and ligand design directed at deoxyuridine 5'-triphospate nucleotidohydrolase
(Master thesis; Mastergradsoppgave, 2014-07-01)dUTPase is an important enzyme in DNA metabolism. It can be thought of as a gate keeper for apoptosis and is therefore an attractive target when trying to kill malign cells which cause disease in the human body. dUTPase has been found to be an important drug target in diseases such as cancer and malaria, to mention two. Due to problems with drug resistance in existing treatments, the search for new ... -
Reconstructing Omni-kernel control flow
(Master thesis; Mastergradsoppgave, 2014-12-15)Today, with the prevalence of many- and multi-core systems has it been sparked a new interest for programming models that permits developer to exploit their resources. This has sparked renewed interest in creating larger event-based systems, systems where stack ripping occurs and with an obfuscated control flow. Both increases the complexity of debugging errors. During the development of the ... -

A Multiscale Wavelet-Based Test for Isotropy of Random Fields on a Regular Lattice
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-12-31)A test for isotropy of images modeled as stationary or intrinsically stationary random fields on a lattice is developed. The test is based on wavelet theory, and can operate on the horizontal and vertical scale of choice, or on any combination of scales. Scale is introduced through the wavelet variances (sometimes referred to as the wavelet power spectrum), which decompose the variance over ... -

Magnitude of extreme heat waves in present climate and their projection in a warming world
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)An extreme heat wave occurred in Russia in the summer of 2010. It had serious impacts on humans and natural ecosystems, it was the strongest recorded globally in recent decades and exceeded in amplitude and spatial extent the previous hottest European summer in 2003. Earlier studies have not succeeded in comparing the magnitude of heat waves across continents and in time. This study introduces a new ... -
