(Bachelor thesis, 2024)Generell relativitetsteori er i forkant av moderne fysikk. Flere tester på teorien er høyt verdsatt, for a skyve fysikkens grenser. Ett spesifikt felt dette kan anvendes på er periapsis presesjon av planeter. Denne oppgaven ... -
Identification, mapping, and photobiology of Arctic macro- and microalgae using ROV-UHI
(Doctoral theses at NTNU;2024:237, Doctoral thesis, 2024)This thesis comprises firstly of method development, using a newly developed remotely operated vehicle carrying an underwater hyperspectral imaging camera (mini-ROV-UHI) for identification and mapping of brown, green and ... -
A Full-Field Crystal Plasticity Study on the Bauschinger Effect Caused by Non-Shearable Particles and Voids in Aluminium Single Crystals
(Journal article; Peer reviewed, 2024)In the present work, the goal is to use two-scale simulations to be incorporated into the full-field open software DAMASK version 2.0.3 crystal plasticity framework, in relation to the Bauschinger effect caused by the ... -
A Concept for a Multipurpose Time-of-Flight Neutron Reflectometer at Compact Neutron Sources
(Journal article; Peer reviewed, 2024)The design of a time-of-flight neutron reflectometer proposed for the new generation of compact neutron sources is presented. The reflectometer offers the possibility to use spin-polarized neutrons. The reflectometer design ... -
Sampling time for different matrices in stress assessment of farmed Atlantic salmon post-smolt
(Journal article; Peer reviewed, 2024)The sustainability of commercial aquaculture production depends critically on prioritizing fish welfare management. Besides monitoring welfare parameters such as fish behaviour and water quality, fish stress level can also ... -
Effect of microstructure on precipitation of β-Mg2Si during cooling of Al-Mg- Si alloys
(Doctoral theses at NTNU;2024:228, Doctoral thesis, 2024)Processing of Al-Mg-Si alloys requires tight control of the various secondary Mg-Si phases that form during the processing steps. In this regard, the cooling stage after homogenisation is a crucial step because of the ... -
The effect of grain size and rolling reduction on microstructure evolution and annealing hardening response of a Mg-3Gd alloy
(Journal article; Peer reviewed, 2024)Mg-3Gd (wt.%) samples with different initial grain sizes were prepared to evaluate the grain size effect on microstructural evolution during cold rolling and subsequent annealing hardening response. The deformation behavior ... -
Development and application of cultivation and analytical workflows for the study of cellular responses to antibiotics in E. coli
(Doctoral theses at NTNU;2024:127, Doctoral thesis, 2024)Antibiotics revolutionized medicine during the 1900s. However, a void in new discoveries in the last decades and increased antibiotic resistance are major threats to society. New antibiotics are highly needed to cope with ... -
Socio-Ecological Perspectives of Avifauna Conservation in the Indawgyi Wetland Ecosystem, Myanmar
(Doctoral theses at NTNU;2024:156, Doctoral thesis, 2024)Wetlands are the most productive ecosystems in the world and play a crucial role in avian conservation. However, wetland ecosystems are closely associated with anthropogenic landscapes and their avifauna are affected by ... -
Topological superconductivity induced by a Kitaev spin liquid
