      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 

      Sinton, Julia Claire (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 

      Aghabalaei, Anita (Masteroppgave/UIS-TN-IMN/2013;, Master thesis, 2013)
