Characterization of Linked Polymer Solutions (LPS) – Influence of salinity and divalent ions
(The University of Bergen, 2011-05-31)
Water flooding with addition of polymers cross-linked by polyvalent ions (LPS) has proven to increase the oil recovery both in field applications and laboratory studies, but with constraints on the brine salinity. With of ...
Robust Control Volume Methods for Reservoir Simulation on Challenging Grids
(The University of Bergen, 2010-02-19)
Ciliary photoreceptors in the cerebral eyes of a protostome larva
(BioMed Central, 2011-03-01)
Background: Eyes in bilaterian metazoans have been described as being composed of either ciliary or rhabdomeric photoreceptors. Phylogenetic distribution, as well as distinct morphologies and characteristic deployment ...
Circulation and transformation of Atlantic and Arctic water masses in climate models
(The University of Bergen, 2011-12-09)
Ocean heat transport and associated heat loss to the atmosphere contributes significantly to the anomalously mild climate of northwestern Europe and its variability. In this thesis, the circulation and transformation of ...
Quality of the Analysis Step in EnKF
(The University of Bergen, 2011-06-15)
In many physical applications we want to characterize the parameters of a system based on indirect observations or measurements. In a reservoir simulator setting, the goal is to simulate the production of hydrocarbons ...
Value of different data types for estimation of permeability
(The University of Bergen, 2011-06-01)
The interrelation between sensitivity, non-linearity and scale, associated with the inverse problem of identifying permeability from measurements of fluid flow, is considered. The gouverning equations for fluid flow in a ...
The notion of ‘responsible development’ in new approaches to governance of nanosciences and nanotechnologies
(The University of Bergen, 2010-10-08)
This PhD dissertation looks at the development of nanosciences and nanotechnologies (nanoST), a field that has gained tremendous political and economic momentum in the first decade of the 21st century. It is also a field ...
Gene expression in bryozoan larvae suggest a fundamental importance of pre-patterned blastemic cells in the bryozoan life-cycle
(BioMed Central, 2011-06-06)
Background: Bryozoa is a clade of aquatic protostomes. The bryozoan life cycle typically comprises a larval stage, which metamorphoses into a sessile adult that proliferates by asexual budding to form colonies. The homology ...
Transport of inorganic carbon through, within, and below the ocean surface
(The University of Bergen, 2011-03-11)
Human emissions of CO2 through the burning of fossil fuel, cement production, and land use change have increased the atmospheric CO2 concentration by 39 % since 1750. Without the large uptake of anthropogenic CO2 by the ...
Effect of uneven sampling along an environmental gradient on transfer-function performance
We investigate the effect that uneven sampling of the environmental gradient has on transfer-function performance using simulated community data. We find that cross-validated estimates of the root mean squared error ...
