Intermolecular charge transfer enhances two-photon absorption in yellow fluorescent protein
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)We present a quantum chemical study of the two-photon absorption (TPA) properties of yellow fluorescent protein (YFP), a mutant of the extensively studied green fluorescent protein. The aromatic chromophore of YFP has a π-stacking interaction with the aromatic ring of a tyrosine residue (Tyr203) in a parallel-displaced structure with a distance of about 3.4 Å. We study the TPA spectrum of the ... -

Problemløsning i matematikk i videregående skole. Hva kan arbeid med problemløsning tilby elevenes helhetlige matematiske kompetanse
(Master thesis; Mastergradsoppgave, 2014-05-30)Problemløsning har vært, og er fremdeles en sentral del av lærerplanen i matematikk. Elevene skal kunne analysere og omforme et problem i matematisk form, løse dette og vurdere dets gyldighet. Undersøkelser som TIMSS Advanced 2008 og PISA 2013 viser at norsk matematikkundervisning er ensformig. Der individuell oppgaveregning er gjenganger, noe mine observasjoner også bekreftet. Andre land som ... -
Symmetry transformation groups and differential invariants
(Master thesis; Mastergradsoppgave, 2014-11-15)There exists a local classification of finite-dimensional Lie algebras of vector fields in two complex dimensions. We lift the Lie algebras from this classification to three complex dimensions. -
Muntlig arbeid med sannsynlighet på videregående skole. En kvalitativ studie om bruk av muntlig aktivitet for å fremme elevers begrepsforståelse i sannsynlighet
(Master thesis; Mastergradsoppgave, 2014-05-29)Matematikkundervisningen i norsk skole er preget av individuelle arbeidsmåter og oppgaveregning. En konsekvens av dette er at elevene får liten mulighet til å bygge opp begrepsmessige strukturer. I denne studien har jeg sett nærmere på bruk av muntlig aktivitet i arbeid med sannsynlighet, og jeg har utført en kvalitativ studie med elever på første året i videregående skole. Problemstillingen min var ... -
The formation of optical shocks for paraxial pulses propagating in weakly nonlinear and weakly dispersive materials
(Master thesis; Mastergradsoppgave, 2014-06-02)In this thesis leading order asymptotic equations describing the propagation of approximately paraxial pulses in a weakly nonlinear and weakly dispersive medium are derived using the method of multiple scales, and the formation of optical shocks in the nondispersive, purely paraxial case is investigated. How the state of polarization influences the shock have in particularly been looked in to. -
Deforming the vacuum. On the physical origin and numerical calculation of the Casimir effect.
(Master thesis; Mastergradsoppgave, 2014-05-14)A new method for calculating the Casimir force between compact objects was introduced in May 2012 by Per Jakobsen and Isak Kilen. In this method a regularization procedure is used to reduce the pressure to the solution of an integral equation defined on the boundaries of the objects. In this thesis the method is further developed by extending from a 2D to a 3D massless scalar field, subject to ... -

Subglacial roughness of the former Barents Sea ice sheet
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)The roughness of a glacier bed has high importance for the estimation of the sliding velocity and can also provide valuable insights into the dynamics and history of ice sheets, depending on scale. Measurement of basal properties in present-day ice sheets is restricted to ground-penetrating radar and seismics, with surveys retrieving relatively coarse data sets. Deglaciated areas, like the Barents ... -

Structural development and metallogenesis of Paleoproterozoic volcano-sedimentary rocks of the Rombak Tectonic Window
(Doctoral thesis; Doktorgradsavhandling, 2014-10-30)The Rombaken Tectonic Window (RTW) is a basement culminations within the Caledonian thrust nappes in northern Norway. It appear as an inlier of Paleoproterozoic supracrustal rocks on Paleoproterozoic basement rocks. The RTW consist of several metasedimentary and metavolcanic N-S striking belts enclosed within large granitic bodies. The RTW marks the boundary between Archean basement rocks to the ...
