ALICE TPC Upgrade Activities for LHC Run 3 and Beyond: "SAMPA ASIC Tests with GEM Detector Prototype"
(Master thesis, 2015-09-11)The Time Projection Chamber (TPC) signal readout of the ALICE detector is being upgraded to accommodate the higher collision rates and -energies during LHC Run 3 in 2018. Due to the increased collision rates, the TPC drift ... -
The ALICE TPC, a large 3-dimensional tracking device with fast readout for ultra-high multiplicity events
(Peer reviewed; Journal article, 2010-10-01)The design, construction, and commissioning of the ALICE Time-Projection Chamber (TPC) is described. It is the main device for pattern recognition, tracking, and identification of charged particles in the ALICE experiment ... -
The ALICE Transition Radiation Detector: Construction, operation, and performance
(Peer reviewed; Journal article, 2018-02)The Transition Radiation Detector (TRD) was designed and built to enhance the capabilities of the ALICE detector at the Large Hadron Collider (LHC). While aimed at providing electron identification and triggering, the TRD ... -
Alien plants, animals, fungi and algae in Norway:an inventory of neobiota
(Peer reviewed; Journal article, 2019-08-03)We present the results of an inventory and status assessment of alien species in Norway. The inventory covered all known multicellular neobiota, 2496 in total, 1039 of which were classified as naturalised. The latter ... -
Alien species in Norway: Results from quantitative ecological impact assessments
(Journal article, 2020)1. Due to globalisation, trade and transport, the spread of alien species is increasing dramatically. Some alien species become ecologically harmful by threatening native biota. This can lead to irreversible changes in ... -

Alignment of the ATLAS Inner Detector in Run 2
(Journal article; Peer reviewed, 2020-12-24)The performance of the ATLAS Inner Detector alignment has been studied using pp collision data at s√=13TeV collected by the ATLAS experiment during Run 2 (2015–2018) of the Large Hadron Collider (LHC). The goal of the ... -
Alkyl-phenanthrenes in early life stage fish: differential toxicity in Atlantic haddock (Melanogrammus aeglefinus) embryos
(Journal article; Peer reviewed, 2023)Tricyclic polycyclic aromatic hydrocarbons (PAHs) are believed to be the primary toxic components of crude oil. Such compounds including phenanthrene are known to have direct effects on cardiac tissue, which lead to ... -
Alkylation of TEB Acetylide Using Tosylates
(Master thesis, 2018-12-19)Alkylated products of 3,3,4,4-tetraethoxybut-1-yne (TEB) where prepared from alkylation of the TEB acetylide with a selection of alkyl tosylates, obtained by tosylation of the corresponding tosylates, and alkyl iodides in ... -
Alkylfenolers innvirkning på glyserofosfolipidmembraner og kolesterol i torskehjerne
(Master thesis, 2003)Oljeindustrien slipper ut store mengder produsert vann, som inneholder flere potensielle giftstoffer, blant annet alkylfenoler. Det ble tidlig vist at alkylfenoler kan ha skadelig virkning, særlig på grunn av østrogenhermende ... -

Along‐stream, seasonal, and interannual variability of the North Icelandic Irminger Current and East Icelandic Current around Iceland
(Journal article; Peer reviewed, 2020)Data from repeat hydrographic surveys over the 25-year period 1993 to 2017, together with satellite altimetry data, are used to quantify the temporal and spatial variability of the North Icelandic Irminger Current (NIIC), ... -
Alps to Apennines zircon roller coaster along the Adria microplate margin
(Peer reviewed; Journal article, 2018-02-09)We have traced the particle path of high-pressure metasedimentary rocks on Elba Island, Northern Apennines, with the help of a U-Pb-Hf detrital zircon study. One quarter of the analysed zircons are surprisingly young, ... -

Alterations in auditory brain stem response distinguish occasional and constant tinnitus
(Journal article; Peer reviewed, 2022)BACKGROUND. The heterogeneity of tinnitus is thought to underlie the lack of objective diagnostic measures. METHODS. Longitudinal data from 20,349 participants of the Swedish Longitudinal Occupational Survey of Health ... -
Altered collective mitochondrial dynamics in the Arabidopsis msh1 mutant compromising organelle DNA maintenance
(Journal article; Peer reviewed, 2022)Mitochondria form highly dynamic populations in the cells of plants (and almost all eukaryotes). The characteristics and benefits of this collective behaviour, and how it is influenced by nuclear features, remain to be ... -
Altering the wetting properties of FEP films by nano-structuring the surface using reactive ion etching
(Master thesis, 2017-10-18)Renewable energy sources has become a large field of research, and in the recent years, methods to harvest energy from rain drops have been developed. This technology is based on rain drops rolling or sliding on a polymer ... -
Alternative gauge for the description of the light-matter interaction in a relativistic framework
(Peer reviewed; Journal article, 2017-08)We present a generalized velocity gauge form of the relativistic laser-matter interaction. In comparison with the (equivalent) regular minimal coupling description, this form of light-matter interaction results in superior ... -
Alternative læringsmåter for derivasjon i R1 - en komparativ analyse
(Master thesis, 2016-06-01)I denne masteroppgaven har jeg studert elever som har arbeidet med derivasjon i matematikk R1. Formålet har vært å sammenligne to alternative læringsmåter med tradisjonell oppgaveregning, med tanke på læringsutbytte på ... -
An altitude and distance correction to the initial fluence distribution of TGFs
