Eastward-Propagating Planetary Waves Prior to the January 2009 Sudden Stratospheric Warming
(Peer reviewed; Journal article, 2021)Eastward-propagating planetary waves (EPWs) were investigated prior to the boreal January 2009 major sudden stratospheric warming (SSW) event simulated by the National Center for Atmospheric Research's Whole Atmosphere ... -
Eat or sleep: Availability of winter prey explains mid-winter and spring activity in an Arctic Calanus population
(Peer reviewed; Journal article, 2020)Copepods of the genus Calanus have adapted to high levels of seasonality in prey availability by entering a period of hibernation during winter known as diapause, but repeated observations of active Calanus spp. have been ... -
EBSD based in-situ observationsof polycrystalline materials in the SEM
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:81, Doctoral thesis, 2009)The present PhD thesis is concerned with electron backscatter diffraction (EBSD) based in-situ observations of fine-scaled polycrystalline microstructures during thermomechanical processing in the scanning electron microscope ... -
EBSD Characterization of the Microstructure Evolution in (σ, χ)-containing SDSS Subjected to Long Term Heating
(Journal article; Peer reviewed, 2019)Super duplex stainless steels (SDSS) are used in oil wells with high temperature and high pressure in the oil and gas industry due to the good combination of high corrosion resistance and excellent mechanical properties. ... -
EBSD karakterisering av et austenittisk rustfritt AISI 304 stål under in situ deformasjon ved ulike temperaturer
(Master thesis, 2014)Denne masteroppgaven kartlegger martensittdannelsen i et austenittisk rustfritt stål som følge av ytre påkjenninger i form av temperatur og spenning. Dette er gjort ved hjelp av in situ deformasjon i skanning elektronmikroskop ... -
EBSD Microstructure Characterization of 9% Nickel Steel during In Situ Heat Treatment
(Master thesis, 2015)The austenite content in 9% Ni steel was investigated with EBSD during and after in situ heating to different temperatures in the two phase region of the phase diagram, after first obtaining a coarse grained HAZ using weld ... -
EBSD Quantification of Retained Austenite in 9% Ni Steel Related to Thermal Treatments
(Chapter, 2015)The present work has been to study the effect of different finalizing preparation techniques on the amount of retained austenite measured with Electron Backscatter Diffraction (EBSD) and X-Ray-Diffraction (XRD) analysis. ... -
EBSD undersøkelser og in situ strekktesting av stål i SEM
(Master thesis, 2012)Denne masteroppgaven har tatt for seg undersøkelser av stål designet for lavtemperaurappliksjoner ved bruk av elektronmikroskop i kombinasjon med diffraksjon av tilbakespredte elektroner (Electron Backscatter Diffraction ... -
EBSD-karakterisering av et HSLA-stål under in situ varmebehandling
(Master thesis, 2011)Ved sveising av HSLA-stål (High Strength Low Alloy) designet for lavtemperatur applikasjoner kan det dannes lokale sprø soner som martensitt/austenitt-faser (MA-faser). Det er derfor ønskelig å karakterisere austenitten ... -
EBSP Indexer - An open-source alternative to commercial EBSD software
(Master thesis, 2023)Elektron tilbakesprednings diffraksjon (EBSD) er blitt en godt etablert metode for å undersøke krystallstrukturer og -orienteringer i krystallografiske materialer, og som resultat har interessen for å presse begrensingene ... -
EBSP Indexer - Using and open-source dictionary indexing software for phase differentiation
(Master thesis, 2023)Denne oppgaven presenterer utviklingen av en gratis programvare for analyse av tilbakespredte elektron diffraksjonsmønster (EBSD) kalt EBSP Indexer. Prosjektet er resultatet av et felles utviklingsarbeid av et team på tre ... -
ECF AND TCF BLEACHING OF SACCHARUM OFFICINERUM-CO89003 BAGASSE SODA-AQ PULP WITH ALKALI-THERMOTOLERANT CRUDE XYLANASE FROM COPRINELLUS DISSEMINATUS SW-1 NTCC1165
(Journal article; Peer reviewed, 2012)An alkali-thermo-tolerant crude xylanase from Coprinellus disseminatus SW-1 NTCC1165 produced under solid-state fermentation conditions improves the brightness of sugarcane bagasse soda-AQ pulp by 7.3, 4.7, 6.1, and 8.2% ... -
ECG augmented pulse oximetry in Atlantic salmon (Salmo salar)—A pilot study
(Peer reviewed; Journal article, 2023)Understanding the tolerance limits of fish is crucial for developing aquaculture operations that ensure good animal welfare. However, there exist little data describing the physiological responses in farmed Atlantic salmon, ... -
Eco-evolutionary feedbacks - theoretical models and perspectives
(Journal article; Peer reviewed, 2018)Theoretical models pertaining to feedbacks between ecological and evolutionary processes are prevalent in multiple biological fields. An integrative overview is currently lacking, due to little crosstalk between the fields ... -
Eco-physiological responses of cold-water corals to anthropogenic sedimentation and particle shape
(Master thesis, 2016)Cold-water coral habitats have been known to science for centuries, but only recently have scientists stated to study them. Among these habitats, also soft corals are found, and they have been even less investigated than ... -
The ecological and evolutionary role of telomere length in house sparrows
(Doctoral theses at NTNU;2021:420, Doctoral thesis, 2021)Telomeres, the DNA sequences capping the ends of linear chromosomes, are ancient molecular structures that are shared among most eucaryotes. The telomeres protect chromosomes from degradation and are vital to genome ... -
Ecological dependencies make remote reef fish communities most vulnerable to coral loss
(Peer reviewed; Journal article, 2021)Ecosystems face both local hazards, such as over-exploitation, and global hazards, such as climate change. Since the impact of local hazards attenuates with distance from humans, local extinction risk should decrease with ... -
Ecological dynamics and large scale phenotypic differentiation in density-dependent populations
(Journal article; Peer reviewed, 2019)Spatial differentiation of phenotypes is assumed to be determined by a combination of fluctuating selection producing adaptations to the local environment and a homogenizing effect of migration. We present a model with ... -
