(Master thesis / Masteroppgave, 1999)Arbeidet i denne hovedoppgaven er en del av et omfattende prosjekt som går ut på å studere strukturen til kjerner ved høy eksitsjonsenergi og lavt spinn. Ved Syklotronlaboratoriet har man konsentrert seg om kjerner tilhørende ...
-
(Master thesis / Hovedoppgave, 2001)Oppgaven gir en beskrivelse av fysikkelevers opplevelse av fysikkundervisningen i videregående skole, hvilke faktorer som påvirker valg av fysikk, og fysikkelevers syn på fysikkfaget. I tillegg gis en beskrivelse av ...

(Master thesis / Hovedoppgave, 2002)DNA-heliksen i cellekjernen er under store deler av cellesyklus kveilet opp og pakket sammen til en mer kompakt struktur ved hjelp av spesielle proteiner, histoner. Det er av interesse å undersøke muligheten for energioverføring ...
-
(Master thesis / Hovedoppgave, 2002)I denne oppgaven har det blitt utviklet en metode for lavdoseratebestråling av celler i kultur, og det har blitt utført innledende eksperimenter for å kartlegge effektene av denne bestrålingen på humane celler. Cellene som ...
-
(Master thesis / Hovedoppgave, 2002)In this thesis I discuss various topics relating to the definition of particles and vacuum states in quantum field theory in general, and apply it to non-inertial reference frames in Minkowski spacetime. The particle concept ...
-
(Master thesis / Hovedoppgave, 2002)The channel H -> gamma gamma is the most promising in which to discover a light Higgs boson with ATLAS at LHC. The ATLAS detector is one of the four experiments at the Large Hadron Collider at CERN and will, according to ...
-
(Master thesis / Hovedoppgave, 2002)The oThe object-oriented (OO) programming style is becoming more and more popular, also among scientists. Several CERN computer libraries have been translated from the Fortran programming language to C++ recently, and ...
-
(Master thesis / Hovedoppgave, 2003)The main goal of the project which this thesis is a part of, is to develop a system that can to track hand movements within a restricted area. The last few years has seen the development of several different relatively ...

Phase separation, transformation and domain formation in LaNbO4 supersaturated with Sr : A TEM study (Master thesis / Hovedoppgave, 2003)We have studied the lanthanum niobate system doped with strontium of nominal composition La_{0.95}Sr_{0.05}NbO_{4}. We observe two phases in the synthesized material. One of these phases is Sr-poor LaNbO_{4}. The other ...
-
(Master thesis / Hovedoppgave, 2003)The main objective of this thesis is to consider the concept of gravitational entropy from a perturbative point of view. A flat, matter dominated universe model is subjected to a linear perturbation, and the entropic ...
-
(Master thesis / Hovedoppgave, 2003)Irradiating T-47D cells with doses below 1 Gy revealed that cells of this line express hyper-radiosensitivity (HRS). In the present study HRS has been investigated when a challenge dose was given 6 or 24 hours after a ...
-
(Master thesis / Hovedoppgave, 2003)Det har den siste tiden (2001-2003)vært stor fokus på bredbåndsutrulling i Norge og også resten av verden. Målet har vært å kunne tilby aksessteknologier og teknologiske plattformer som kan nå ut til alle innbyggere i et ...
-
(Master thesis / Hovedoppgave, 2003)The primary goal of the work in this thesis was to investigate the macroscopic and microscopic nature of dry contact friction at very low velocities. Experiments were carried out using a sandpaper and carpet as contacting ...
-
(Master thesis / Hovedoppgave, 2004)This thesis discusses ways in which history of physics can be useful in physics education. Examples are mainly chosen from the field of electromagnetism. The first chapter deals with objections against the use of history ...
-
(Master thesis / Hovedoppgave, 2004)Ved høyenergetisk strålebehandling av kreft hos kvinner kan dosene til ovariene (eggstokkene) være av betydning for ovariefunksjonen, selv om disse ligger et stykke utenfor primærstrålefeltet. Det vil i hovedsak være spredt ...
-
(Master thesis / Hovedoppgave, 2004)In this thesis, I will address the so called forward problem of electro-magnetics. That is, given a setup of electrodes on a conductive material, can we compute where the current will pass through? More specifically, from ...
-
(Master thesis / Hovedoppgave, 2004)In this thesis, variations in efficiency between two different solar collectors have been measured. Solar collector efficiency has been measured at different levels of flow. In addition, there has been made calculations ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2005)The orientation relationship between ferroelastic domains in LaNbO4 (with 0.5 at.% Sr) is studied by selected area electron diffraction and high-resolution electron microscopy. At room temperature the domains are related ...
-
(Master thesis / Hovedoppgave, 2005)The ekpyrotic universe is a brane cosmology theory with an alternative explanation of the big bang as a collision between two hyperplanes. We first introduce the reader to brane objects in the context of string theory, and ...
