• #### Low Salinity Waterflooding in Combination with Surfactant/Polymer. A Field Scale Simulation Study of Hybrid EOR ﻿

(The University of Bergen, 2018-06-27)
It is projected that 77% of energy consumption will originate from fossil fuels in 2040, indicating a continuous demand for crude oil [1]. Nevertheless, more than half of the hydrocarbons produced at present originate from ...

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

(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 ...

• #### Luminosity determination in pp collisions at s=7 TeV using the ATLAS detector at the LHC ﻿

(Springer, 2011-04-27)
Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at s=7 TeV are presented. The luminosity is independently determined using several detectors and multiple ...

• #### Læring av matematikk gjennom prosjekter i teknologi og design ﻿

(Caspar forlag og kursvirksomhet, 2006)
• #### Læring av naturfag og matematikk gjennom prosjekter i teknologi og design ﻿

(The University of Bergen, 2006)
Jeg nærer en uro. Fagområdet teknologi og design skal inkluderes i matematikkfaget, samt i naturfag og kunst og håndverk. Men vil elevene kunne lære naturfag og matematikk eller få økt innsikt i hvordan anvende naturfag ...

• #### Magnetic coordinate systems ﻿

(Springer, 2017-03)
Geospace phenomena such as the aurora, plasma motion, ionospheric currents and associated magnetic field disturbances are highly organized by Earth’s main magnetic field. This is due to the fact that the charged particles ...

• #### Magnetic Resonance Imaging of Hydrate Phase Transitions in Sediments ﻿

(The University of Bergen, 2017-12-21)
Natural gas hydrates, simplified described as gas compressed in ice, are a substance existing in large quantities around the world. Their existence requires elevated pressures and low temperature. They are therefore found ...

• #### Magnetospheric response and reconfiguration times following IMF By reversals ﻿

(American Geophysical Union, 2017-01)
The interaction between the interplanetary magnetic field (IMF) and the geomagnetic field at the dayside magnetopause leads to transfer of momentum and energy which changes the magnetospheric configuration, but only after ...

• #### Marine seismics with a pulsed combustion source and Pseudo Noise codes ﻿

(Springer, 2007-03)
There has been an ongoing debate for years of how dangerous seismic surveys are with respect to marine life. Marine seismics is today dominated by airgun technology, where high energy is generated by a release of compressed ...

• #### Mass Ordering of Third Generation Sleptons in a Trilinear-Augmented Gaugino Mediated Supersymmetry-Breaking Scenario ﻿

(The University of Bergen, 2017-12-21)
In this thesis, we are exploring the particle spectrum of trilinear-augmented gaugino mediation. In particular, we calculate the masses of the stau and the tau sneutrino in a section of the parameter space in which one is ...
