Original specimens and type localities of early described polychaete species (Annelida) from Norway, with particular attention to species described by O.F. Müller and M. Sars
(Journal article; Peer reviewed, 2014)Early descriptions of species from Norwegian waters are reviewed, with a focus on the basic requirements for reassessing their characteristics, in particular, by clarifying the status of the original material and locating ... -
Orthogeriatrics prevents functional decline in hip fracture patients: report from two randomized controlled trials
(Peer reviewed; Journal article, 2021)Background The incidence of hip fractures are expected to increase in the following years. Hip fracture patients have in addition to their fracture often complex medical problems, which constitute a substantial burden on ... -
Orthogonal decomposition of composition operators on the $H^2$ space of Dirichlet series
(Peer reviewed; Journal article, 2022)Let denote the Hilbert space of Dirichlet series with square-summable coefficients. We study composition operators on which are generated by symbols of the form , in the case that . If only a subset of prime numbers ... -
Orthorhombic-tetragonal phase transition induced by Ta isovalent doping and its effect on fatigue characteristics of KNL-NSTx ceramics
(Journal article; Peer reviewed, 2018)The effect of Ta addition on the bipolar fatigue characteristics of lead-free KNL-NSTx ceramics (x = 0, 0.04, 0.07 and 0.11 mol%) is studied. Bipolar cycling up to 1 × 106 cycles leads to strong degradation of the polarization ... -
Orthotropic fluid diffusion in composite marine structures. Experimental procedure, analytical and numerical modelling of plates, rods and pipes
(Journal article; Peer reviewed, 2018)Finite elements simulations of fluid diffusion for composite structures are becoming more common in marine and offshore applications. Input parameters for such simulations are the orthotropic diffusion constants for the ... -
Oscillating between Conservation and Investment: A Grounded Theory of Students’ Strategies for Optimizing Personal Resources
(Journal article; Peer reviewed, 2015)Students’ use of time and effort during their studies has been discussed exhaustively in mass media and educational research. In most cases, researchers try to give advice to teachers on how to get their students to become ... -
Oscillation analysis of low-voltage distribution systems with high penetration of photovoltaic generation
(Peer reviewed; Journal article, 2020)The use of renewable power generation brings new challenges related to power quality issues. Furthermore, with the changing power system nature due to the presence of new components such as power electronics in large numbers ... -
Oscillatory Convection Onset in a Porous Rectangle with Non-analytical Corners
(Peer reviewed; Journal article, 2020)The analytical theory on Darcy–Bénard convection is dominated by normal-mode approaches, which essentially reduce the spatial order from four to two. This paper goes beyond the normal-mode paradigm of convection onset in ... -
Oscillatory Non-normal-Mode Onset of Convection in a Porous Rectangle
(Journal article; Peer reviewed, 2019)A special case of the fourth-order Darcy–Bénard problem in a two-dimensional (2D) rectangular porous box is investigated. The present eigenfunctions are of non-normal-mode type in the horizontal and vertical directions. ... -
Osimertinib in non-small cell lung cancer with uncommon EGFR-mutations: a post-hoc subgroup analysis with pooled data from two phase II clinical trials
(Peer reviewed; Journal article, 2022)Background: Osimertinib is standard of care for EGFR-mutated non-small cell lung cancer (NSCLC) patients. The efficacy of the drug in patients with mutations other than the common deletion in exon 19 and L858R in exon 21 ... -
Osimertinib in T790M-positive and -negative patients with EGFR-mutated advanced non-small cell lung cancer (the TREM-study)
(Peer reviewed; Journal article, 2020)Objectives In non-small cell lung cancer patients with acquired resistance to first- or second-generation EGFR-TKIs, osimertinib is approved in the presence of the T790 M resistance mutation. We assessed the efficacy of ... -
OSL dating of Weichselian ice-free periods at Skorgenes, Western Norway
(Journal article; Peer reviewed, 2018)During recent years, many sites with sediments pre-dating the Last Glacial Maximum have been identified in formerly glaciated areas. As more and better dates are presented from these sites, the dynamic behaviour of the ... -
Osteocyte-Like Cells Differentiated From Primary Osteoblasts in an Artificial Human Bone Tissue Model
