Is there genetic variation in the response to competition intensity in juvenile brown trout Salmo trutta?
(Journal article; Peer reviewed, 2011)Effects of intraspecific competition intensities on the relative performance (growth and movement) of juvenile brown trout Salmo trutta originating from nine different families were tested in tank experiments and in ... -
Is there plasticity in developmental instability? The effect of daily thermal fluctuations in an ectotherm
(Journal article; Peer reviewed, 2017)Diversified bet‐hedging (DBH) by production of within‐genotype phenotypic variance may evolve to maximize fitness in stochastic environments. Bet‐hedging is generally associated with parental effects, but phenotypic variation ... -
Is there really a “golden hour” for work disability interventions? a narrative review
(Journal article; Peer reviewed, 2019)The subacute phase of low back pain has been termed as the “golden hour” to intervene to prevent work disability. This notion is based on the literature up to 2001 and is limited to back pain. In this narrative review, we ... -
Is This Us? The Construction of European Woman/Man in the Exhibition It's Our History!
(Journal article; Peer reviewed, 2011)On the 50th anniversary of the Treaty of Rome, the non-profit organisation Musée de l’Europe staged the exhibition It’s our history!. The subject of It’s our history! was the history of European integration from 1945 to ... -
Is trade policy a missing piece to a public health puzzle?
(Journal article, 2018)Health outcomes vary across different welfare state arrangements (Bergqvist et al., 2013). Strikingly, while overall health is typically better in social democratic countries (Denmark, Finland, Norway, Sweden), these ... -
Is vaginal breech delivery associated with higher risk for perinatal death and cerebral palsy compared with vaginal cephalic birth? Registry-based cohort study in Norway.
(Journal article; Peer reviewed, 2017)Objective This paper aims to study if vaginal breech delivery is associated with increased risk for neonatal mortality (NNM) or cerebral palsy (CP) in Norway where vaginal delivery accounts for 1/3 of all breech ... -
Isbjørnens effekt på fugl i et arktisk klima i endring - Sluttrapport for Svalbards miljøvernfond
(NINA Rapport;1163, Research report, 2015)Arktis blir stadig varmere og utbredelsen av havis blir mindre. Det forandrer leveområdet til de mange artene som er avhengige av havis. Isbjørnen er avhengig av havis for å jakte på sel, og økende lengde på den isfrie ... -
Isentropic fluid dynamics in a curved pipe
(Journal article; Peer reviewed, 2016)In this paper we study isentropic flow in a curved pipe. We focus on the consequences of the geometry of the pipe on the dynamics of the flow. More precisely, we present the solution of the general Cauchy problem for ... -
Islam, Oil, and the Middle East Region: An Empirical Analysis of the Repression of Religion, 1980-2013
(Journal article; Peer reviewed, 2017)There is a lively debate on the relative impacts of Islam, oil wealth, and Middle Eastern institutional legacies regarding democratization and the spread of liberal values. We examine this issue using religious repression. ... -
Isogeometric Analysis of Acoustic Scattering using Infinite Elements
(Journal article; Peer reviewed, 2018)Isogeometric analysis (IGA) has proven to be an improvement on the classical finite element method (FEM) in several fields, including structural mechanics and fluid dynamics. In this paper, the performance of IGA coupled ... -
Isogeometric analysis of acoustic scattering with perfectly matched layers (IGAPML)
(Peer reviewed; Journal article, 2022)The perfectly matched layer (PML) formulation is a prominent way of handling radiation problems in unbounded domain and has gained interest due to its simple implementation in finite element codes. However, its simplicity ... -
Isogeometric analysis of finite deformation nearly incompressible solids
(Peer reviewed; Journal article, 2011)This paper addresses the use of isogeometric analysis to solve finite deformationsolid mechanics problems, in which volumetric locking may be encountered. The current workis based on the foundation developed in the project ... -
Isogeometric analysis of THM coupled processes in ground freezing
(Journal article; Peer reviewed, 2017)An isogeometric analysis (IGA) based numerical model is presented for simulation of thermo-hydro-mechanically (THM) coupled processes in ground freezing. The momentum, mass and energy conservation equations are derived ... -
Isogeometric analysis using LR B-splines
(Journal article; Peer reviewed, 2014)The recently proposed locally refined B-splines, denoted LR B-splines, by Dokken et al. (2013) [6] may have the potential to be a framework for isogeometric analysis to enable future interoperable computer aided design and ... -
Isogeometric boundary element method for acoustic scattering by a submarine
(Journal article; Peer reviewed, 2019)Isogeometric analysis with the boundary element method (IGABEM) has recently gained interest. In this paper, the approximability of IGABEM on 3D acoustic scattering problems will be investigated and a new improved BeTSSi ... -
Isogeometric collocation for implicit dynamics of three-dimensional beams undergoing finite motions
(Journal article; Peer reviewed, 2019)We propose a novel approach to the implicit dynamics of shear-deformable geometrically exact beams, based on the isogeometric collocation method combined with the Newmark time integration scheme extended to the rotation ... -
