Directed flow of charged particles at mid-rapidity relative to the spectator plane in Pb-Pb collisions at \(\sqrt{s_{NN}}\)=2.76 TeV
(Peer reviewed; Journal article, 2013-12)The directed flow of charged particles at midrapidity is measured in Pb-Pb collisions at \(\sqrt{s_{NN}}\).2.76 TeV relative to the collision plane defined by the spectator nucleons. Both, the rapidity odd \(v_1^{odd}\) ... -
Directed graph representation of half-rate additive codes over GF(4)
(Peer reviewed; Journal article, 2010)We show that (n, 2n) additive codes over GF(4) can be represented as directed graphs. This generalizes earlier results on self-dual additive codes over GF(4), which correspond to undirected graphs. Graph representation ... -
Directed Network of Substorms Using SuperMAG Ground‐Based Magnetometer Data
(Peer reviewed; Journal article, 2019)We quantify the spatiotemporal evolution of the substorm ionospheric current system utilizing the SuperMAG 100+ magnetometers. We construct dynamical directed networks from this data for the first time. If the canonical ... -
Directional wave measurements from navigational buoys
(Journal article; Peer reviewed, 2022)In-situ wave measurements are often required by marine industry standards and for verification of coastal wave forecasts. Obtaining wave measurements is costly and it would be advantageous to utilize existing platforms ... -
Directional wave measurements using an autonomous vessel
(Peer reviewed; Journal article, 2016-08-01)An autonomous vessel, the Offshore Sensing Sailbuoy, was used for wave measurements near the Ekofisk oil platform complex in the North Sea (56.5º N, 3.2º E, operated by ConocoPhillips) from 6 to 20 November 2015. Being 100 ... -
Directly measured currents and estimated transport pathways of Atlantic Water between 59.58N and the Iceland-Faroes-Scotland Ridge
(Peer reviewed; Journal article, 2015-11-24)Using vessel-mounted acoustic Doppler current profiler data from four different routes between Scotland, Iceland and Greenland, we map out the mean flow of water in the top 400 m of the northeastern North Atlantic. The ... -
Direkte bruk av nanofluider som kjølevæske i en dieselmotor
(Master thesis, 2023-06-01)The work carried out in this thesis is the characterization and investigation of carbon- based nanofluids as a potential engine coolant for a single-cylinder diesel engine. Car- bon black particles could be sufficiently ... -
Disappearance of Pacific Water in the northwestern Fram Strait
(Journal article, 2005-07-28)Water of Pacific origin, entering the Arctic Ocean through the Bering Strait, exits the Arctic Ocean through the Canadian Archipelago and the Fram Strait. The amount and timing of Pacific Water export through these gates ... -
Discards of cod (Gadus morhua) in the Norwegian coastal fisheries: improving past and future estimates
(Journal article; Peer reviewed, 2022)Discarding can be an unknown source of biases and uncertainties in stock assessments. Discarding patterns and quantities vary so a routine methodology for estimating discards is important to give a better picture of total ... -
Discovery of active off-axis hydrothermal vents at 9° 54′N East Pacific Rise
(Journal article; Peer reviewed, 2022)Comprehensive knowledge of the distribution of active hydrothermal vent fields along midocean ridges is essential to understanding global chemical and heat fluxes and endemic faunal distributions. However, current knowledge ... -
Discovery of Nuclear-Encoded Genes for the Neurotoxin Saxitoxin in Dinoflagellates
(Peer reviewed; Journal article, 2011-05-18)Saxitoxin is a potent neurotoxin that occurs in aquatic environments worldwide. Ingestion of vector species can lead to paralytic shellfish poisoning, a severe human illness that may lead to paralysis and death. In ... -
The discovery of the Younger Dryas, and comments on the current meaning and usage of the term
(Journal article; Peer reviewed, 2021)The Younger Dryas (YD) cold event was discovered in Denmark by Hartz and Mithers in 1904 and the term coined by Hartz in 1912. It was identified as a lacustrine clay bed containing plant macrofossils of an Arctic flora, ... -

Discriminating between surfaces of peripheral membrane proteins and reference proteins using machine learning algorithms
(Master thesis, 2019-04-05)In biology, the cell membrane is an important component of a cell and usually works as a “fence” to distinguish the inside and outside of a cell. The key role is to protect the cells from being interfered by their surroundings ... -
Discrimination of n-3 Rich Oils by Gas Chromatography
(Peer reviewed; Journal article, 2010-11-22)Exploring the capabilities of instrumental techniques for discriminating n-3 rich oils derived from animals is a very important though much neglected area that was emphasized more than 100 years ago. In this study the ... -
A discussion on turbulent and undular bores using the models from the shallow water equations and the dispersive system.
(Master thesis, 2010-05-26)The bore is a wave phenomenon that occurs in channels and rivers of shallow water. Referred to as a discharge wave, a bore is generated by a sudden increase of water flow. Bores appear in certain rivers as the tide pushes ... -
Disentangling effects and context dependencies of climate change on alpine plants
(Doctoral thesis, 2022-12-02)Klimaendringer byr på nye utfordringer for fjellplanter, og påvirker dem både direkte gjennom å endre fysiologiske prosesser, og indirekte gjennom endringer i interaksjoner mellom planter. Disse indirekte effektene kan ... -
Disentangling electron-boson interactions on the surface of a familiar ferromagnet
(Journal article; Peer reviewed, 2024)We report energy renormalizations from electron-phonon and electron-magnon interactions in spin minority surface resonances on Ni(111). The different interactions are identified, disentangled, and quantified from the ...
