Multi-analytical investigation into painting materials and techniques: the wall paintings of Abuna Yemata Guh church
(Peer reviewed; Journal article, 2016)Abuna Yemata Guh is one of the nine Saints who are traditionally claimed to have come to Northern Ethiopia in the beginning of the sixth century and established monasteries in the Tigray region. The church, named after ... -
Multi-commodity price risk hedging in the Atlantic salmon farming industry
(Peer reviewed; Journal article, 2021)Cost management has received limited attention in the aquaculture industry due to historically high profit margins. This trend, however, is not likely to continue. This creates a need for knowledge on optimally managing ... -
Multi-component interfacial transport as described by the square gradient model: evaporation and condensation.
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:176, Doctoral thesis, 2009)The aim of this thesis is to build a theoretical approach which allows to describe the behavior of fluid during evaporation and condensation in multicomponent systems. We consider isotropic non-polarizable mixtures. We ... -
Multi-method atomistic modelling of sodium-carbon interactions: Atomistic modelling towards the increased durability of carbon cathodes in primary aluminium production
(Doctoral theses at NTNU;2017:9, Doctoral thesis, 2017)Karbonmaterialer brukes som kledning under produksjonen av primærmetall. Høy temperatur, strøm og et kjemisk tærende miljø sliter materialene under drift. En bidragende årsak til slitasjen er inntrengning av natrium. ... -
Multilevel CC2 and CCSD in Reduced Orbital Spaces: Electronic Excitations in Large Molecular Systems
(Peer reviewed; Journal article, 2021)We present efficient implementations of the multilevel CC2 (MLCC2) and multilevel CCSD (MLCCSD) models. As the system size increases, MLCC2 and MLCCSD exhibit the scaling of the lower-level coupled cluster model. To treat ... -
Multilevel CC2 and CCSD Methods with Correlated Natural Transition Orbital
(Peer reviewed; Journal article, 2019)In the multilevel coupled cluster approach, an active orbital space is treated at a higher level of coupled cluster theory than the remaining inactive orbitals. We introduce the multilevel CC2 method where CC2 is used for ... -
Multilevel coupled cluster methods for large molecular systems
(Doctoral theses at NTNU;2020:240, Doctoral thesis, 2020)The coupled cluster hierarchy of models can be used to accurately describe electronic excitations in molecular systems. However, the standard coupled cluster models are expensive and their cost severely limits the size of ... -
Multilevel coupled cluster theory: Development, implementation and application of multilevel coupled cluster theory for core and valence excited states
(Doctoral thesis at NTNU;2016:267, Doctoral thesis, 2016)This thesis consist of seven papers and an introduction describing the ongoing development and applications of multilevel coupled cluster theory. Coupled cluster theory is one of the most accurate, but also one of the ... -
Multiomics analysis of rheumatoid arthritis yields sequence variants that have large effects on risk of the seropositive subset
(Peer reviewed; Journal article, 2022)Objectives To find causal genes for rheumatoid arthritis (RA) and its seropositive (RF and/or ACPA positive) and seronegative subsets. Methods We performed a genome-wide association study (GWAS) of 31 313 RA cases (68% ... -
Multiple-stressor effects in an apex predator: combined influence of pollutants and sea ice decline on lipid metabolism in polar bears
(Journal article; Peer reviewed, 2017)There is growing evidence from experimental and human epidemiological studies that many pollutants can disrupt lipid metabolism. In Arctic wildlife, the occurrence of such compounds could have serious consequences for ... -
Multiscale models for large molecular systems: from development to applications
(Doctoral theses at NTNU;2023:17, Doctoral thesis, 2023)The atomistic description of complex molecular systems, such as solutions and biological moieties, requires some sort of compromise between computational efforts and accuracy. Low-level models can treat thousands of atoms, ... -
Multiscale partial charge estimation on graphene for neutral, doped and charged flakes
(Journal article; Peer reviewed, 2018)The minimal-basis iterative stockholder (MBIS) and restrained electrostatic potential (RESP) methods were applied to examine the effects of edges and of nitrogen and boron dopants on the atomic partial charges of neutral ... -
Nanoparticle Dynamics in Composite Hydrogels Exposed to Low-Frequency Focused Ultrasound
(Peer reviewed; Journal article, 2023)Pulsed focused ultrasound (FUS) in combination with microbubbles has been shown to improve delivery and penetration of nanoparticles in tumors. To understand the mechanisms behind this treatment, it is important to evaluate ... -
Nanoporous materials can tune the critical point of a pure substance
(Journal article; Peer reviewed, 2015)Molecular simulations and NMR relaxometry experiments demonstrate that pure benzene or xylene confined in isoreticular metal–organic frameworks (IRMOFs) exhibit true vapor–liquid phase equilibria where the effective critical ... -
