Of tests, trochs, shells, and spicules: Development of the basal mollusk Wirenia argentea (Solenogastres) and its bearing on the evolution of trochozoan larval key features
(Peer reviewed; Journal article, 2010-01-26)Background The phylogenetic status of the aplacophoran mollusk taxon Solenogastres (Neomeniomorpha) is controversially discussed. Some authors propose the clade to represent the most basal branch within Mollusca, while ... -
Offshore hydrogen production from floating offshore wind - a study of UNITECH Zefyros.
(Master thesis, 2022-06-01)The aim of this thesis is to review design considerations and study the effect of a variable power supply of offshore hydrogen production by an electrolyser inside the turbine tower of a floating offshore wind turbine. To ... -
Offshore Wind Farm Wake Effect on Stratification and Coastal Upwelling
(Peer reviewed; Journal article, 2015-12-02)In this study, the interactions between an offshore wind farm, upper-ocean currents, and stratification are examined under shallow water conditions from a two-dimensional modeling standpoint. The modeling results from two ... -
Offshore wind power and hydrogen for oil and gas platform electrification

Offshore wind turbine wake characteristics using scanning doppler lidar
(Peer reviewed; Journal article, 2017-10)Within an offshore wind park, wind flow characteristics are quite complex and govern both the energy production and the structural wind turbine response. An experimental study focussed on assessing the spatial variability ... -
Oh no, it’s raining! A study of how information in online weather reports is interpreted, integrated, and used in everyday decision-making by laypeople
(Doctoral thesis, 2016-11-18)Different people in different occupations depend on weather forecasts to plan their work and recreational schedules. People with no expertise in meteorology frequently interpret weather forecasts and uncertainty information. ... -
OikoBase: a genomics and developmental transcriptomics resource for the urochordate Oikopleura dioica
(Peer reviewed; Journal article, 2013-11-26)We report the development of OikoBase (http://oikoarrays.biology.uiowa.edu/Oiko/), a tiling array-based genome browser resource for Oikopleura dioica, a metazoan belonging to the urochordates, the closest extant group to ... -
Oil absorption stability of modified cellulose porous materials with super compressive strength in the complex environment
(Journal article; Peer reviewed, 2023)The occurrence of oil spills has severe damage upon both the environment and human health. Hence, the development of a green, recyclable, complex environment resistant, and efficient oil–water separation aerogel is required ... -
Oil droplet fouling and differential toxicokinetics of polycyclic aromatic hydrocarbons in embryos of Atlantic haddock and cod
(Peer reviewed; Journal article, 2017-07-05)The impact of crude oil pollution on early life stages (ELS) of fish, including larvae and embryos, has received considerable attention in recent years. Of the organic components present in crude oil, polycyclic aromatic ... -
Oil Spill Modeling in Sea Ice Covered Ocean
(Master thesis, 2021-06-01)The ongoing reduction in extent and thickness of sea ice in the Arctic allows the expansion of shipping activity and oil exploration in the high north, and with that a potential increased risk of oil spill in ice covered ... -
The Okavango Delta: Fisheries in a fluctuating floodplain system
(Journal article; Peer reviewed, 2022)Wetlands are among the most productive ecosystems globally characterized by dynamic interactions between terrestrial and aquatic habitats at different scales. These systems support valuable floodplain fisheries that are a ... -
«Okei, hvilken konklusjon kan vi trekke ut fra det?» Ein kvalitativ studie av kjenneteikn ved lærars bruk av spørsmål og innspel i utforskande gruppediskusjonar
(Master thesis, 2021-06-01)Å vere lærar i dagens klasserom inneber i langt større grad enn før å la elevane vere aktive deltakarar i eiga læring. Dette medfører at læraren i si undervisning kjem i direkte dialog med elevar, og at det læraren gjer i ... -
Old and new equations for maximal heart rate prediction in patients with heart failure and reduced ejection fraction on beta-blockers treatment: results from the MECKI score data set
(Journal article; Peer reviewed, 2022)Aims Predicting maximal heart rate (MHR) in heart failure with reduced ejection fraction (HFrEF) still remains a major concern. In such a context, the Keteyian equation is the only one derived in a HFrEF cohort on optimized ... -
OLS Dialog: An open-source front end to the Ontology Lookup Service
(Peer reviewed; Journal article, 2010-01-17)Background: With the growing amount of biomedical data available in public databases it has become increasingly important to annotate data in a consistent way in order to allow easy access to this rich source of information. ... -
Om kvantilregresjon
(Master thesis, 2008)Vi skal i denne oppgaven beskrive teorien bak kvantilregresjon. I klassisk regresjonsanalyse bruker man minste kvadraters metode, hvor man beregner betingede gjennomsnittsestimater av forventningen til responsvariabelen. ... -
