Er konsum av melk og egg assosiert med risiko for kreft? Foreløpige resultater fra en prospektiv undersøkelse
(Peer reviewed; Journal article, 1997) -
Erosjon, avsetninger og mekanismer i forbindelse med dannelsen av Hellmogjelet, Tysfjord, Nord-Norge
(Master thesis, 2013-06-03)Det finnes store krefter i strømmende vann. Kreftene kommer godt til syne når vassdrag flommer over av smeltevann om våren eller etter perioder med mye regn. Hva ville skjedd dersom en vannmengde tilsvarende 2/3 av Amazonas ... -
Erosjonsrater og landskapsutvikling på Andøya, Vesterålen
(Master thesis, 2020-11-03)Andøya antas å ha vært dekket av is flere ganger gjennom kvartærtiden. Området består av både storskala landformer, som strandflaten og platåområder, og mindre landformer som for eksempel morenerygger og smeltevannsgjel. ... -
Error Detection and Correction for Symmetric and Asymmetric Channels
(Doctoral thesis, 2007-08-27)When a message is sent over a channel errors can occur due to noise during the transmission. So it is very important to know the error correction and detection capability of the code, which is used to encode the message. ... -
Escape mortality of cod, sithe and haddock in a Barents Sea trawl fishery
(Peer reviewed; Journal article, 2006)Experiments are described to investigate the survival of gadoid sh in the Barents Sea escaping from a demersal trawl, with and without a sorting grid, at high and low levels of shing intensity. The mortality for cod (Gadus ... -
Escape- and diet-history among farmed Atlantic Salmon caught in Norwegian rivers and coast in the period 2011-2021
(Master thesis, 2022-06-01)Every year thousands of farmed Atlantic salmon (Salmo salar) escape from net pens in Norway, and introgression has been documented in two-thirds of the more than 200 wild populations investigated thus far. Farmed salmon ... -
Escapement of gadoid fish beneath a commercial bottom trawl : relevence to the overall trawl selectivity
(Fisheries Research, Peer reviewed; Journal article, 2006)Escapement of Atlantic cod (Gadus morhua), haddock (Melanogrammus aegle nus) and saithe (Pollachius virens) beneath a commercial bottom trawl, rigged with a 60 cm diameter rockhopper gear, was studied in the Barents Sea. ... -
The Escherichia coli alkA Gene Is Activated to Alleviate Mutagenesis by an Oxidized Deoxynucleoside
(Journal article; Peer reviewed, 2020)The cellular methyl donor S-adenosylmethionine (SAM) and other endo/exogenous agents methylate DNA bases non-enzymatically into products interfering with replication and transcription. An important product is 3-methyladenine ... -
ESD Reviews: Climate feedbacks in the Earth system and prospects for their evaluation
(Peer reviewed; Journal article, 2019)Earth system models (ESMs) are key tools for providing climate projections under different scenarios of human-induced forcing. ESMs include a large number of additional processes and feedbacks such as biogeochemical cycles ... -
Essays on Portfolio Risk Management and Weather Derivatives
(Doctoral thesis, 2023-08-25)Denne avhandlingen handler om utvikling og praktisk implementering av risikostyringsmetoder for investeringsporteføljer, energiporteføljer, og håndtering av vær- og forurensningsrisiko. Avhandlingen inkluderer tre ... -
Establishing a homogeneous and stable sand pack to study parameters during spontaneous imbibition
(Master thesis, 2018-06-20)Spontaneous imbibition is an important process for oil production during water flooding in porous media and has been widely studied for decades to understand the physics of the process for different boundary conditions. ... -
Establishing fin whale fibroblast culture conditions for toxicological studies
(Master thesis, 2022-10-03)Several marine mammal species have been hunted to near extinction by humans. As such, many of these species are vulnerable to population reductions due to changing climate, destruction of habitats, and environmental ... -
Establishing reward systems for excellence in teaching – the experience of academics pioneering a reward system
(Journal article; Peer reviewed, 2023)Higher education institutions are struggling to elevate the value and status of academic teaching. In this endeavour, rewards for excellence in teaching are becoming a common measure. This study reports on the experience ... -
Establishment of killer whale (Orcinus orca) primary fibroblast cell cultures and their transcriptomic responses to pollutant exposure
(Journal article; Peer reviewed, 2023)Populations of killer whale (Orcinus orca) contain some of the most polluted animals on Earth. Yet, the knowledge on effects of chemical pollutants is limited in this species. Cell cultures and in vitro exposure experiments ... -
Establishment of Pinus wallichiana on a Himalayan glacier foreland: stochastic distribution or safe sites?
(Peer reviewed; Journal article, 2006)The establishment of tree seedlings in primary succession is thought to occur only after an adequate reserve of nutrients has accumulated in the soil. Individuals of Pinaceae are sometimes reported to grow on very recently ... -
Estimating a mean transport velocity in the marginal ice zone using ice-ocean prediction systems
(Journal article; Peer reviewed, 2022)Understanding the transport of objects and material in the marginal ice zone (MIZ) is critical for human operations in polar regions. This can be the transport of pollutants, such as spilled oil, or the transport of objects, ... -
Estimating fin whale distribution from ambient noise spectra using Bayesian inversion
(Master thesis, 2015-06-01)Passive acoustic monitoring is increasingly used to study the distribution and migration of marine mammals. Marine mammal vocalizations are transient sounds, but the combined sound energy of a population continuously ... -
Estimating Fish Densities from Single Fish Echo Traces
(Peer reviewed; Journal article, 2009)Estimating mean fish density per unit area has been done by counting single fish echo traces with a split beam echo sounder system in the open sea. A data program has been written that scans the acoustic signals for echo ... -
Estimating genetic diversity in a domesticated population of Norwegian Atlantic salmon (Salmo salar) using genomic data
(Master thesis, 2017-12-15)New developments of high throughput sequencing technologies have allowed for breeders to assess values related to loss of genetic diversity in domesticated animals on a genomic level for better accuracy than the pedigree ... -
Estimating global artisanal fishing fleet responses in an era of rapid climate and economic change
(Journal article; Peer reviewed, 2023)There is an urgent need to assess the extent to which the global fishing enterprise can be sustainable in the face of climate change. Artisanal fishing plays a crucial role in sustaining livelihoods and meeting food security ...
