Heavy-flavour hadron decay leptons in Pb–Pb and Xe–Xe collisions at the LHC with ALICE
(Peer reviewed; Journal article, 2019)Heavy quarks, i.e. charm and beauty, are sensitive probes of the medium produced in high-energy heavy-ion collisions. They are produced in the early stage of the collision, mainly in hard partonic scattering processes, and ... -

Height Determination of a Blue Discharge Observed by ASIM/MMIA on the International Space Station
(Journal article; Peer reviewed, 2023)We analyze simultaneous photometric observations of thundercloud discharges from the Modular Multispectral Imaging Array of the Atmosphere-Space Interactions Monitor (ASIM) on board the International Space Station with ... -
Helium radiography with a digital tracking calorimeter—a Monte Carlo study for secondary track rejection
(Journal article; Peer reviewed, 2021)Radiation therapy using protons and heavier ions is a fast-growing therapeutic option for cancer patients. A clinical system for particle imaging in particle therapy would enable online patient position verification, ... -
Helminths associated with terrestrial slugs in some parts of Europe
(Journal article; Peer reviewed, 2020)A survey of helminths associated with terrestrial slugs focusing on the invasive Arion vulgaris and the native A. ater was conducted on populations from France, Germany, Netherlands, Norway and Poland. In total, 648 ... -
Hematophagy in the salmon louse (Lepeophtheirus salmonis) : Characterization of genes and proteins involved in parasite blood-feeding
(Doctoral thesis, 2020-02-13)The salmon louse (Lepeophtheirus salmonis) is an obligate, hematophagous ectoparasite infecting salmonid fish such as the Atlantic salmon (Salmo salar). The parasite is at present the number one threat to the Norwegian ... -
Hemipelagic deposits on the Mendeleev and northwestern Alpha submarine Ridges in the Arctic Ocean: acoustic stratigraphy, depositional environment and an inter-ridge correlation calibrated by the ACEX results
(Peer reviewed; Journal article, 2010)The first high resolution multichannel seismic data from the Mendeleev and Alpha Ridges in the Arctic Ocean have been used to investigate the depositional history, and compare acoustic stratigraphies of the three main ... -
Hensikter med lekser i biologiundervisning. En kvalitativ studie av læreres begrunnelser for bruk av lekser i biologifagene i videregående skole
(Master thesis, 2017-06-20)Using homework is a long tradition within Norwegian schools and in most countries. Homework is not embedded in the Norwegian curriculum and hence most teachers choose if they want to give homework or not. Research shows ... -
HEPPA III Intercomparison Experiment on Electron Precipitation Impacts: 1. Estimated Ionization Rates During a Geomagnetic Active Period in April 2010
(Journal article; Peer reviewed, 2022)Precipitating auroral and radiation belt electrons are considered an important part of the natural forcing of the climate system. Recent studies suggest that this forcing is underestimated in current chemistryclimate models. ... -
Heppa III Intercomparison Experiment on Electron Precipitation Impacts: 2. Model-Measurement Intercomparison of Nitric Oxide (NO) During a Geomagnetic Storm in April 2010
(Journal article; Peer reviewed, 2022)Precipitating auroral and radiation belt electrons are considered to play an important part in the natural forcing of the middle atmosphere with a possible impact on the climate system. Recent studies suggest that this ... -
Herbivory damage but not plant disease under experimental warming is dependent on weather for three subalpine grass species
(Journal article; Peer reviewed, 2022)Both theory and prior studies predict that climate warming should increase attack rates by herbivores and pathogens on plants. However, past work has often assumed that variation in abiotic conditions other than temperature ... -
Herding mesopelagic fish by light
(Peer reviewed; Journal article, 2019)To assess organisms forming mesopelagic scattering layers in the Red Sea, we took advantage of their reactions to light. We used a remotely operated vehicle (ROV) equipped with LED lamps for herding the acoustic targets ... -
The heritability curve and its applications to human non-Mendelian traits
(Doctoral thesis, 2023-12-08)Arvbarhet er et viktig mål for å beskrive en ikke-mendelsk egenskap; den måler i hvilken andel verdien av egenskapen påvirkes av genetisk materiale. I klassiske biometriske modeller er arvbarheten konstant over hele ... -
Herring (Clupea harengus) in Lindåspollene before and during spawning: spatial decisions and school dynamics
(Master thesis, 2011-06-01)Abstract This study reports on the school dynamics of a self-sustained local population of Atlantic herring (Clupea harengus) in Lindåspollene, south-western Norway, during pre-spawning and spawning, observed over a period ... -
Heterogeneity of impacts of high CO2 on the North Western European shelf
(Peer reviewed; Journal article, 2014-02-03)The increase in atmospheric CO2 is a dual threat to the marine environment: from one side it drives climate change, leading to modifications in water temperature, circulation patterns and stratification intensity; on the ... -
Heterogeneous distributed calibration framework for the high level trigger in ALICE
(Doctoral thesis, 2009-02-13)This thesis focusses on the development of a distributed and re-configurable online calibration environment for the ALICE (A Large Ion Collider Experiment) HLT (High Level Trigger). ALICE1 is one of the four major experiments ... -
Heterogeneous distribution of plankton within the mixed layer and its implications for bloom formation in tropical seas
(Peer reviewed; Journal article, 2015-06-11)Intensive sampling at the coastal waters of the central Red Sea during a period of thermal stratification, prior to the main seasonal bloom during winter, showed that vertical patches of prokaryotes and microplankton ... -
Heterogeneous Hydrate Nucleation on Calcite {1014} and Kaolinite {001} Surfaces: A Molecular Dynamics Simulation Study
(Master thesis, 2016-06-01)Natural gas hydrates are of significant interest due to the great amount of methane that can potentially be utilised as an energy source. These methane resources are trapped in ice-like form, which is a concern since ... -
Heterotrophic nanoflagellate grazing facilitates subarctic Atlantic spring bloom development
