Elevator speech: Students’ discussions of forces and acceleration by means of a scale in an elevator
(Peer reviewed; Journal article, 2022)Students’ challenges in learning mechanics are well documented from test situations, and group discussions are considered a fruitful way to meet these challenges. In this paper, we present a study from an authentic teaching ... -
Eliashberg study of superconductivity induced by interfacial coupling to antiferromagnets
(Peer reviewed; Journal article, 2021)We perform Eliashberg calculations for magnon-mediated superconductivity in a normal metal, where the electron-magnon interaction arises from interfacial coupling to antiferromagnetic insulators. In agreement with previous ... -
Elucidating the pathogenesis of osteochondrosis using nonlinear optical microscopy
(Doctoral theses at NTNU;2017:309, Doctoral thesis, 2017)Abstract Osteochondrosis is defined as a focal disturbance in endochondral ossification and causes joint pain and lameness in several species of animals, including humans. The focal disturbance occurs at predilection ... -
Emisjon av ultrafiolett lys fra positive streamere i sykloheksan
(Master thesis, 2016)Isolerende væsker for elektriske komponenter, går til gjennomslag ved høyt elektrisk felt grunnet et fenomen kalt streamere. Streamere er elektrisk ledende kanaler av gass eller plasma som propagerer raskere desto høyere den ... -
Emission decay and energy transfer in Yb/Tm Y-codoped fibers based on nano-modified glass
(Journal article, 2015)We report the results of an experimental investigation and theoretical analysis of luminescence decay in Yb/Tm Y-codoped fibers based on nano-modified glass. Based on the experimental results, numerical simulations allowed ... -
Emission of coherent THz magnons in an antiferromagnetic insulator triggered by ultrafast spin–phonon interactions
(Peer reviewed; Journal article, 2023)Antiferromagnetic materials have been proposed as new types of narrowband THz spintronic devices owing to their ultrafast spin dynamics. Manipulating coherently their spin dynamics, however, remains a key challenge that ... -
Emulsions in Polymeric Turbulence
(Master thesis, 2022)Rapporten introduserer grunnleggende teori for Newtonsk turbulens, med fokus på andre ordens strukturfunksjon for hastighet og energispektrum. Formalismen for turbulens blir så brukt på ferske resultater for turbulent ... -
En DFT analyse på kobber basert metallisk-organisk dekomponerings blekk
(Master thesis, 2020)En ny generasjon av kobber basert elektronisk blekk har blitt nylig utviklet som dekomponeres til metallisk kobber under varme. Blekkene er basert på kobber format komplekser i en +2 oksidasjonstall, som reduseres til en ... -
En EXAFS-studie av DFT-modellerte AuCu-nanopartikler: Cupiditas de SmAug
(Master thesis, 2014)En strukturstudie av AuCu-nanopartikler har blitt gjennomført ved hjelp av DFT og EXAFS. Det ble i alt undersøkt 18 DFT-modellerte AuCu-nanopartikler med størrelser fra 38 til 80 atomer og varierende støkiometrisk ... -
En studie av samspillet mellom YouTube-videoer og samarbeidslæring
(Master thesis, 2010)I denne oppgaven har jeg sett på hvordan bruk av YouTube-videoer i samspill medsamarbeidslæring kan benyttes i fysikkundervisningen, og hvilken betydning det kan ha for elevenes læringsutbytte. Jeg argumenterer for at ... -
Energy Considerations of Initiation of Fast Streamers in Cyclohexane
(Master thesis, 2015)The purpose of this study is to improve a model of streamer propagation in dielectric liquid by Hestad et al. at Sintef Energy Research, by considering the energy in an initiated second mode streamer. This is important, ... -
Energy Landscape of Alginate-Epimerase Interactions Assessed by Optical Tweezers and Atomic Force Microscopy
(Journal article, 2015)Mannuronan C-5 epimerases are a family of enzymes that catalyze epimerization of alginates at the polymer level. This group of enzymes thus enables the tailor-making of various alginate residue sequences to attain various ... -
Energy Metabolism Is Altered in Radioresistant Rectal Cancer
(Peer reviewed; Journal article, 2023)Resistance to neoadjuvant chemoradiation therapy is a significant clinical challenge in the management of rectal cancer. There is an unmet need to identify the underlying mechanisms of treatment resistance to enable the ... -
Energy spectra and scaling relations in numerical turbulence with laboratory and astrophysical applications
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:163, Doctoral thesis, 2004)In this work we have focused on the statistical properties of turbulence. This has been done in two different settings; one with neutral gas (the first four papers) and the other with ionized gas (the last four papers). ... -
Engineered Surfaces for Redirection of Light
