U-Pb zircon provenance of metamorphosed clastic sediments in a developing rift (Dom Feliciano Belt, Uruguay and Kaoko Belt, Namibia)
(Master thesis, 2014-11-17)Geochronological studies of the westernmost part of the Kaoko Belt in Namibia, the Coastal Terrane, revealed zircons with distinct Neoproterozoic ages, that are no known from other parts of this orogen and an exotic origin ... -
Udvikling af elevers matematiske forståelse gennem helklassediskussion
(Journal article; Peer reviewed, 2021)I denne artikel vil jeg på baggrund af udvalgt litteratur og empiri diskutere og give eksempler på, hvordan en matematiklærer kan gennemføre en dialog på klassen. Klasserumsdialoger kritiseres ofte, og somme tider med god ... -
Ulike interesser på ulike trinn? - En komparativ studie av elevers interesse for å lære biologi, med fokus på elevtyper, klasser og trinn
(Master thesis, 2020-06-18)Denne masteroppgaven har som formål å undersøke og beskrive elevers interesse for å lære biologi ved å benytte klyngeanalyse til å identifisere elevtyper. Oppgaven bruker et kvantitativt forskningsdesign med spørreskjema ... -
Ultralydsmålinger under høyt trykk - En undersøkelse av solubilisering av 1-heksanol i natrium dodecylsulfat som funksjon av trykk
(Master thesis, 2005)Ny apparatur for lydhastighetsmålinger under trykk har blitt testet, og tilpasset rubidium-klokke teknikk. Det ble deretter gjort studier på solubiliseringsprosessen som funksjon av trykk, der en variert mengde av 1-heksanol ... -
Ultramafic rock carbonation: Constraints from listvenite core BT1B, Oman Drilling Project
(Journal article; Peer reviewed, 2020)The occurrence of the quartz-carbonate alteration assemblage (listvenite) in ophiolites indicates that ultramafic rock represents an effective sink for dissolved CO2. However, the majority of earlier studies of ultramafic ... -

Ultrastructure of the anterior organ and posteriorfunnel-shaped canal of Gyrocotyle urna Wagener, 1852(Cestoda: Gyrocotylidea)
(Peer reviewed; Journal article, 2015-05-22)Using scanning and transmission electron microscopy, ultrastructure of the anterior organ and posterior funnel-shaped canal of Gyrocotyle urna Wagener, 1852 (Cestoda: Gyrocotylidea) from ratfish, Chimaera monstrosa ... -
The UN decade of ocean science for sustainable development
(Peer reviewed; Journal article, 2019-07-31)Our civilization needs a clean, resilient, productive, safe, well-observed, documented and predicted ocean. “The ocean we need for the future we want” was the motto of the Intergovernmental Oceanographic Commission proposal ... -
An Unaccounted Fraction of Marine Biogenic CaCO3 Particles
(Peer reviewed; Journal article, 2012-10-23)Biogenic production and sedimentation of calcium carbonate in the ocean, referred to as the carbonate pump, has profound implications for the ocean carbon cycle, and relate both to global climate, ocean acidification and ... -
Unaccounted mortality in purse seine fisheries. Quantification and mitigation of slipping mortality
(Doctoral thesis, 2014-06-06)Purse seining is an efficient fishing method that is used to catch most of the world’s pelagic fish species. In some of these fisheries slipping is used to adjust catch size, increase catch value or to release illegal ... -
UncertainData.jl: a Julia package for working with measurements and datasets with uncertainties
(Journal article; Peer reviewed, 2019-11-01)UncertainData.jl provides an interface to represent data with associated uncertainties for the Julia programming language (Bezanson, Edelman, Karpinski, & Shah, 2017). Unlike Measurements.jl (Giordano, 2016), which deals ... -
Uncertainties in Arctic sea ice thickness and volume: new estimates and implications for trends
(Peer reviewed; Journal article, 2014-04-22)Sea ice volume has decreased in the last decades, evoked by changes in sea ice area and thickness. Estimates of sea ice area and thickness rely on a number of geophysical parameters which introduce large uncertainties. To ... -
Uncertainty and ignored information in the analysis of bat ultrasound: Bayesian approximation to the rescue
(Journal article; Peer reviewed, 2022)Bat ultrasound analysis has been around for several decades and it is one of the most important tools in studies of bat ecology. Discrimination between species is based on intra-specific features of echolocation calls. ... -
Uncertainty estimation in sound scattering measurements within an anechoic chamber
(Master thesis, 2022-01-07)Uncertainty was estimated for seven variable changes in sound scattering measurements in an anechoic chamber to explore their impact individually and compared to each other. These variables were change of loudspeaker, ... -
Uncertainty in twenty-first century projections of the Atlantic Meridional Overturning Circulation in CMIP3 and CMIP5 models
(Peer reviewed; Journal article, 2016-05-26)Uncertainty in the strength of the Atlantic Meridional Overturning Circulation (AMOC) is analyzed in the Coupled Model Intercomparison Project Phase 3 (CMIP3) and Phase 5 (CMIP5) projections for the twenty-first century; ... -
Unclear associations between small pelagic fish and jellyfish in several major marine ecosystems
(Peer reviewed; Journal article, 2019-02-28)During the last 20 years, a series of studies has suggested trends of increasing jellyfish (Cnidaria and Ctenophora) biomass in several major ecosystems worldwide. Some of these systems have been heavily fished, causing a ... -
