  • Karakterisering av silika nanopartikler for økt oljeutvinning 

    Pettersen, Birgitte (The University of Bergen, 2014-09-01)
    Anvendelsen av silika nanopartikler for EOR-formål krever stabile dispersjoner ved typiske reservoarforhold. Optimale silikadispersjoner vil være stabile over lengre tid ved nøytrale pH- verdier og høye elektrolyttko ...

  • Kinetic description of particle emission from expanding source 

    Magas, Volodymyr; Csernai, Lászóo Pal (Elsevier, 2008-05-22)
    The freeze out of the expanding systems, created in relativistic heavy ion collisions, is discussed. We combine kinetic freeze out equations with Bjorken type system expansion into a unified model. The important feature ...

  • Limits on the production of the standard model Higgs boson in pp collisions at s=7 TeV with the ATLAS detector 

    The ATLAS Collaboration; Aad, Georges; Abbott, Brad; Abdallah, Jalal; Abdelalim, A. A.; Buanes, Trygve (Springer, 2011-09-20)
    A search for the Standard Model Higgs boson at the Large Hadron Collider (LHC) running at a centre-of-mass energy of 7 TeV is reported, based on a total integrated luminosity of up to 40 pb−1 collected by the ATLAS detector ...

  • Long lived charginos in Natural SUSY? 

    Bomark, Nils-Erik; Kvellestad, Anders; Lola, Smaragda; Osland, Per; Raklev, Are (Springer, 2014-05-05)
    Supersymmetric models with a small chargino-neutralino mass difference, and as a result metastable charginos, have been a popular topic of investigation in collider phenomenology. The possibility of a chargino lighter ...

  • Long-range interactions and dynamics of excited atoms 

    Simonsen, Sigrid Ina (The University of Bergen, 2010-06-10)
    A study of the dynamics of excited hydrogenic atoms, with emphasis on analytical and numerical calculations of the time-independent and the time-dependent Schrõdinger equation. A short description of Rydberg atoms and their ...

  • Low Salinity Waterflood in Combination with Surfactant/Polymer: Effect of Brine Composition 

    Mjøs, Jon Endre Seljeset (The University of Bergen, 2014-06-02)
    The effect of low salinity water (LSW) on enhanced oil recovery has been known for decades. Although much research is done on the topic, a general agreement of the prevailing mechanism for the low salinity effect has still ...

  • Low-energy surface vibration measurements on the alpha-quartz (0001) surface 

    Luneng, Jenny Louise (The University of Bergen, 2011)
    Despite the enormous range of usages, only little is known about the dynamic and structural properties of quartz (SiO2) surfaces on the atomic scale. The main reason for this is probably that quartz is an insulator, with ...
