(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Temaet for masteroppgaven er ``Elementer i dynamisk teori for røntgendiffraksjon''. Oppgaven har utgangspunkt i C. G. Darwins to artikler fra 1914 og hatt som mål å gå igjennom disse på en pedagogisk måte. Det er lagt vekt ... -
Røntgendiffraksjon : Darwins dynamiske teori for transmisjonsgeometri
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)En sentral teori innen fagfeltet røntgendiffraksjon, har tradisjonelt vært Ewald-von Laue teorien. En annen, mindre nyttet teori er den Darwin publiserte i 1914. Denne oppgaven tar først utgangspunkt i den kinematiske ... -
Screening for biosurfactant-producing bacteria for crude oil degradation, under cool and saline conditions
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06)Using three sources with different hydrocarbon exposure histories—bacteria grown from Arctic seawater (Arctic), and bacteria from an offshore wastewater treatment system from both the bioreactor (BR) and settling chamber ... -
Search for new technologies that can give environmental benefits to the oil industry, subsea waterflooding
(Masteroppgave/UIS-TN-IMN/2013;, Master thesis, 2013)The goal of the oil producing companies are to extract hydrocarbon from the reservoir and make it available to customers. From an environmental perspective, it should be achieved with zero accidents, no harm to people, no ... -
Self-Absorption corrections in Fluorescence EXAFS
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06-13)Variation of the absorption properties as a function of energy across, or near, an absorption edge is known as EXAFS (Extended X-ray Absorption Fine Structure). This technique implies scanning over an absorptionedge and ... -
Semisimple Lie Group theory with application in geometric invariant theory
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06-01)The goal of this thesis was to learn about the theory of Lie algebras, Lie groups and some real geometric invariant theory, with emphasis on semisimple Lie group theory. The material in this thesis was not known to me ... -
Size estimation of nano-particles from synchrotron X-ray data
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06-15)Three samples of Ag2SO4 powder were heated up from 380 °C to 540 °C and then cooled down to 380 °C using an in-house made heat blower with a thermo-couple based temperature controller. During the heating process, synchrotron ... -
Sludge production in chemical precipitation
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06)Ferric chloride as in many other wastewater plants is used as a coagulant in wastewater treatment at Ivar (SNJ) since its multivalence nature has a significant effect on overcoming the stability of particles and consequently ... -
Smart water for eor by membranes
(Masteroppgave/UIS-TN-IMN/2014;, Master thesis, 2014-06-26)Design of smart water for carbonate reservoir, using membrane process is the focus of the thesis. The desirable characteristics of smart water is low salinity or low NaCl concentrations while retaining divalent ions such ... -
Some models for the magnetization of the drilling mud
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06)The problem that a magnetic drilling mud cause to the accuracy of the directional drilling technology is outlined. The purpose of the work is identified in the theoretical modelling of the magnetic response of the magnetic ... -
Sorbose and the Hyphal branching rhythm in neurospora crassa : the influence of sorbose on growth, morphology, period and temperature compensation
(Masteroppgave/UIS-TN-IMN/2008, Master thesis, 2008)The glucose analogue sorbose has an interesting effect on the growth of the fungus Neurospora crassa. On sorbose Neurospora crassa wild type (wt) grows slower and with a marked difference in morphology. The appearance ... -
Sorption of nitrates to activated carbon
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Stormwater is an increasing global threat to water quality in water bodies. Urbanization is expanding, and so is the amount of impermeable surfaces that prevents water seepage into the ground. This is disturbing the natural ... -
