The Vitruvian Baby: Interactive Reformation of Fetal Ultrasound Data to a T-Position
(Peer reviewed; Journal article, 2019)Three-dimensional (3D) ultrasound imaging and visualization is often used in medical diagnostics, especially in prenatal screening. Screening the development of the organs of the fetus as well as the overall growth is ... -
Voices of young biosphere stewards on the strengths, weaknesses, and ways forward for 74 UNESCO Biosphere Reserves across 83 countries
(Journal article; Peer reviewed, 2021)Young stakeholders are key actors in social-ecological systems, who have the capacity to be agents of sustainability transformation but are also at high risk of exclusion in the unfolding of global change challenges. Despite ... -
Volatility modelling in time and space
(Doctoral thesis, 2020-11-06)This thesis contributes to the scientific community in several aspects. We introduce both spatial- and spatio-temporal extensions to the family of GARCH and ARMA-GARCH models and present asymptotic statistics for the quasi ... -
Volcanic evolution of an ultraslow-spreading ridge
(Journal article; Peer reviewed, 2023)Nearly 30% of ocean crust forms at mid-ocean ridges where the spreading rate is less than 20 mm per year. According to the seafloor spreading paradigm, oceanic crust forms along a narrow axial zone and is transported away ... -
The Volcanic Hazards of Jan Mayen Island (North-Atlantic)
(Journal article; Peer reviewed, 2022)Hazard assessment of remote volcanic islands provides many challenges compared to other volcanoes and volcanic fields. Here we present the first systematic volcanic hazard assessment of Jan Mayen Island, a remote island ... -
Volcanic rocks at the Møre Marginal High: geochemistry, petrogenesis and emplacement mechanisms
(Master thesis, 2017-06-13)The opening of the Norwegian-Greenland Sea at the Paleocene−Eocene transition was accompanied by extensive magmatic activity, giving rise to the North Atlantic Igneous Province. The magmatic activity is today manifested ... -
Volcanically hosted venting with indications of ultramafic influence at Aurora hydrothermal field on Gakkel Ridge
(Journal article; Peer reviewed, 2022)The Aurora hydrothermal system, Arctic Ocean, hosts active submarine venting within an extensive field of relict mineral deposits. Here we show the site is associated with a neovolcanic mound located within the Gakkel Ridge ... -
Volcaniclastic Dispersal During Submarine Lava Effusion: The 2012 Eruption of Havre Volcano, Kermadec Arc, New Zealand
(Journal article; Peer reviewed, 2020)Understanding clast dispersal from subaqueous volcanism is hampered by uncertainty in the source and extent of seafloor deposits. Extensive sampling in situ of seafloor deposits from the 2012 submarine eruption of Havre ... -
Volume Increase of the Hippocampus after Electroconvulsive Therapy - The Role of the Electric Field and the Individual Differences due to Body Mass Index, Sex and Age
(Master thesis, 2021-06-15)Electroconvulsive therapy (ECT) involves passing an electrical current through the brain, intentionally causing a brief seizure. In Norway, it is common to calculate the dose according to an age-based method. Recent studies ... -
Volume preserving numerical integrators for ordinary differential equations

Volume transport and mixing of the cold water overflow downstream of the Faroe Bank Channel from one year of moored measurements
(Peer reviewed; Journal article, 2016-03-15)One-year long time series of current velocity and temperature from eight moorings deployed in the Faroe Bank Channel (FBC) are analysed to describe the structure and variability of the dense overflow plume on daily to ... -
Volumetric properties of the nucleosides adenosine, cytidine, and uridine in aqueous solution at T = (288.15 and 313.15) K and p = (10 to 100) MPa
(Journal article; Peer reviewed, 2019)Speeds of sound have been measured for aqueous solutions of the nucleosides adenosine, cytidine, and uridine at the temperatures T = (288.15 and 313.15) K and at the pressures p = (10, 20, 40, 60, 80, and 100) MPa. Using ... -
Vortex interaction in the wake of a two- and three-bladed wind turbine
(Journal article; Peer reviewed, 2020)The vortex interaction in the wake behind a two- and three-bladed model scale wind turbine is investigated. The two rotors have equal solidity, and produce similar power and thrust at the design tip speed ratio. Phase-averaged ... -
Vorticity in peripheral collisions at the Facility for Antiproton and Ion Research and at the JINR Nuclotron-based Ion Collider fAcility
(Peer reviewed; Journal article, 2014-08-29)The flow vorticity development is studied in the reaction plane of peripheral relativistic heavy-ion reactions at energies just above the threshold of the transition to a quark-gluon plasma (QGP). Earlier calculations at ... -
