Environmental impacts of produced water and drilling waste discharges from the Norwegian offshore petroleum industry
(Journal article; Peer reviewed, 2013-09)Operational discharges of produced water and drill cuttings from offshore oil and gas platforms are a continuous source of contaminants to continental shelf ecosystems. This paper reviews recent research on the biological ... -
Epidemiology and classification of gastroenteropancreatic neuroendocrine neoplasms using current coding criteria
(Journal article; Peer reviewed, 2015-09)Background: The lack of uniform criteria for coding of gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) has hampered previous epidemiological studies. The epidemiology of GEP-NEN was investigated in this study ... -
Experimental and computational studies of turbulent mass transfer in a mixing channel
(Journal article; Peer reviewed, 2008)Experiments are carried out for passive mixing in order to obtain local mean and turbulent velocities and concentrations. The mixing takes place in a square channel with two inlets separated by a block. A combined PIV/PLIF ... -
Higher dimensional bivectors and classification of the Weyl operator
(Journal article; Peer reviewed, 2010)We develop the bivector formalism in higher dimensional Lorentzian spacetimes. We define the Weyl bivector operator in a manner consis- tent with its boost-weight decomposition. We then algebraically classify the Weyl ... -
Hyper-Kähler fourfolds and Kummer surfaces
(Journal article; Peer reviewed, 2017-09)We show that a Hilbert scheme of conics on a Fano fourfold double cover of PP2xP2 ramified along a divisor of bidegree (2,2) admits a ℙ 1‐fibration with base being a hyper‐Kähler fourfold. We investigate the geometry of ... -

Inflation with stable anisotropic hair
(Journal article; Peer reviewed, 2011)Recently an inflationary model with a vector field coupled to the inflaton was proposed and the phenomenology studied for the Bianchi type I spacetime. It was found that the model demonstrates a counter-example to the ... -
Inhomogeneous chiral condensate in the quark-meson model
(Journal article; Peer reviewed, 2017-07-24) -
Inverse magnetic catalysis and regularization in the quark-meson model
(Journal article; Peer reviewed, 2015-02)Motivated by recent work on inverse magnetic catalysis at finite temperature, we study the quark-meson model using both dimensional regularization and a sharp cutoff. We calculate the critical temperature for the chiral ... -
Killing superalgebras for Lorentzian four-manifolds
(Journal article; Peer reviewed, 2016-06)We determine the Killing superalgebras underpinning field theories with rigid unextended supersymmetry on Lorentzian four-manifolds by re-interpreting them as filtered deformations of Z-graded subalgebras with maximum odd ... -
Leptogenesis in crossing and runaway regimes.
(Journal article; Peer reviewed, 2014-07)We study the impact of effective thermal masses and widths on resonant leptogenesis. We identify two distinct possibilities which we refer to as ‘crossing’ and ‘runaway’ regimes. In the runaway regime the mass difference ... -
Lil3 assembles with proteins regulating chlorophyll synthesis in barley
(Journal article; Peer reviewed, 2015-06)The light-harvesting-like (LIL) proteins are a family of membrane proteins that share a chlorophyll a/b-binding motif with the major light-harvesting antenna proteins of oxygenic photoautotrophs. LIL proteins have been ... -
Mimicking orchids lure bees from afar with exaggerated ultraviolet signals
(Peer reviewed; Journal article, 2023-01)Flowers have many traits to appeal to pollinators, including ultraviolet (UV) absorbing markings, which are well-known for attracting bees at close proximity (e.g., <1 m). While striking UV signals have been thought to ... -
Natural peptides with antioxidant activity from Atlantic cod and Atlantic salmon residual material
(Journal article; Peer reviewed, 2016-03)Summary. Water-soluble peptides/proteins with molecular weight below 10 kDa were isolated from residual material of cod (liver, skin, and cod mix i.e. skin, frames, and viscera), and salmon (skin, and salmon mix i.e. skin, ... -
Note on the invariant classification of vacuum type D spacetimes
(Journal article; Peer reviewed, 2009-12)We illustrate the fact that the class of vacuum type D spacetimes which are I-non-degenerate are invariantly classified by their scalar polynomial curvature invariants. -

On high-order perturbative calculations at finite density
(Journal article; Peer reviewed, 2017-02)We discuss the prospects of performing high-order perturbative calculations in systems characterized by a vanishing temperature but finite density. In particular, we show that the determination of generic Feynman integrals ... -
On the algebraic classification of pseudo-Riemannian spaces
(Journal article; Peer reviewed, 2011-12)We consider arbitrary-dimensional pseudo-Riemannian spaces of signature (k, k + m). We introduce a boost-weight decomposition and define a number of algebraic properties (e.g. the Si- and N-properties) and present a ... -
On-shell parameter fixing in the quark-meson model
(Journal article; Peer reviewed, 2017-02)The quark-meson model is often used as an effective low-energy model for QCD to study the chiral transition at finite temperature T and baryon chemical potential μB. The parameters in the quark-meson model can be found by ...
