Environmental risk assessment of combined effects in aquatic ecotoxicology: A discussion paper
(Peer reviewed; Journal article, 2014)Environmental regulatory edicts within the EU, such as the regulatory framework for chemicals REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals), the Water Framework Directive (WFD), and the Marine ... 
Lil3 dimerization and chlorophyll binding in Arabidopsis thaliana
(Peer reviewed; Journal article, 2015)The twohelix light harvesting like (Lil) protein Lil3 belongs to the family of chlorophyll binding light harvesting proteins of photosynthetic membranes. A function in tetrapyrrol synthesis and stabilization of geranylgeraniol ... 
EPW Cubes
(Journal article; Peer reviewed, 201608)We construct a new 20dimensional family of projective sixdimensional irreducible holomorphic symplectic manifolds. The elements of this family are deformation equivalent with the Hilbert scheme of three points on a K3 ... 
Some factors affecting the grades of technology students
(Peer reviewed; Journal article, 2017)In this study factors that affect the grades of Norwegian technology students have been investigated. The total data set contained 355.706 individual exams from 63 different engineering master programs during the 2010 to ... 
Science AMA Series: Ask the Society of Environmental Toxicology and Chemistry (SETAC) anything about Pharmaceuticals in the environment!
(Journal article, 2017)The Society of Environmental Toxicology and Chemistry (SETAC) is hosting the SETAC North America 38th annual meeting this week and we have tied this AMA to a specific session, “Pharmaceuticals in the environment: Potential ... 
Inhomogeneous chiral condensate in the quarkmeson model
(Journal article, 2017)The twoflavor quarkmeson model is used as a lowenergy effective model for QCD to study inhomogeneous chiral condensates at finite baryon chemical potential μ B. The parameters of the model are determined by matching the ... 
Exact Solutions of the Field Equations for Empty Space in the Nash Gravitational Theory
(Journal article; Peer reviewed, 201702)John Nash has proposed a new theory of gravity. We define a Nashtensor equal to the curvature tensor appearing in the Nash field equations for empty space, and calculate its components for two cases: 1. A static, spherically ... 
On a class of integrable systems of MongeAmpère type
(Journal article; Peer reviewed, 201706)We investigate a class of multidimensional twocomponent systems of MongeAmpère type that can be viewed as generalisations of heavenly type equations appearing in a selfdual Ricciflat geometry. Based on the JordanKronecker ... 
Universal spacetimes in four dimensions
(Journal article; Peer reviewed, 201710)Universal spacetimes are exact solutions to all higherorder theories of gravity. We study these spacetimes in four dimensions and provide necessary and sufficient conditions for universality for all Petrov types except ... 
Anomalous lowtemperature thermodynamics of QCD in strong magnetic fields
(Journal article; Peer reviewed, 201711)The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ... 
Value regions of univalent selfmaps with two boundary fixed points
(Journal article; Peer reviewed, 2018)In this paper we find the exact value region V(z0,T) of the point evaluation functional f → f(z0) over the class of all holomorphic injective selfmaps f : D → D of the unit disk D having a boundary regular fixed point at ... 
Scattering amplitudes of massive NambuGoldstone bosons
(Journal article; Peer reviewed, 201801)Massive NambuGoldstone (mNG) bosons are quasiparticles the gap of which is determined exactly by symmetry. They appear whenever a symmetry is broken spontaneously in the ground state of a quantum manybody system and at ... 
Chiral density wave versus pion condensation at finite density and zero temperature
(Journal article; Peer reviewed, 201804)The quarkmeson model is often used as a lowenergy effective model for QCD to study the chiral transition at finite temperature T, baryon chemical potential μB, and isospin chemical potential μI. We determine the parameters ...

Atomic scattering factors and atomic crosssections in xray crystallography
(Masteroppgave/UISTNIMF/2018;, Master thesis, 20180615)Crystallographers as well as other scientists and engineers need reliable sets of physical data. Focus is here set upon the xray attenuation coefficients (the atomic photoeffect crosssection, and the incoherent (Compton) ... 
Effect of additives, ball milling and isotopic exchange in porous magnesium borohydride
(Journal article; Peer reviewed, 201808)Magnesium borohydride (Mg(BH4)2) is a promising material for solid state hydrogen storage. However, the predicted reversible hydrogen sorption properties at moderate temperatures have not been reached due to sluggish ... 
Poncelet's Theorem
