• #### Isolation and Identification of Flavonoids Found in Zostera marina Collected in Norwegian Coastal Waters ﻿

(Peer reviewed; Journal article, 2016-05-26)
In extracts of the seagrass Zostera marina, collected in coastal waters of West-Norway, fourteen different flavones and high amounts of rosmarinic acid were identified. Five of the flavones were found to be sulphated, among ...
• #### Isolation of lipid classes from nutritional marine oils: improved extraction strategy and discrimination studies based on the positional distribution of omega-3 polyunsaturated fatty acids on triacylglycerol structures using liquid chromatography tandem mass spectrometry and principal component analysis ﻿

(Master thesis, 2014-03-20)
The consumer of the 21st century have developed an awareness of the quality of food products in their diet and the impact of these products on their health which in turn has led to an escalating consumer demand for omega-3 ...
• #### Isolation, identification and properties of pyranoanthocyanins and anthocyanin forms ﻿

(Doctoral thesis, 2007-06-22)
This dissertation focuses on isolation and structural elucidation of anthocyanins, and their chemical properties. The characterization of anthocyanins from castor (Ricinus communis), fourteen cultivars of European gooseberry ...
• #### Isotopic composition of Pb in tree rings of Norway spruce (Picea abies) from the Fensfjorden area, western Norway ﻿

(Master thesis, 2012-06-01)
The annual growth of tree rings makes the trees as possible archive of the past atmospheric pollution. However, several aspects addressed in literature such as post-depositional mobility of Pb, intra-ring heterogeneity and ...
• #### IsoTrotter: Visually Guided Empirical Modelling of Atmospheric Convection ﻿

(Journal article; Peer reviewed, 2020)
Empirical models, fitted to data from observations, are often used in natural sciences to describe physical behaviour and support discoveries. However, with more complex models, the regression of parameters quickly becomes ...
• #### Iterative Coupling for Fully Dynamic Poroelasticity ﻿

(Journal article; Peer reviewed, 2021)
We present an iterative coupling scheme for the numerical approximation of the mixed hyperbolic-parabolic system of fully dynamic poroelasticity. We prove its convergence in the Banach space setting for an abstract ...
• #### Iterative Linearisation Schemes for Doubly Degenerate Parabolic Equations ﻿

(Conference object; Peer reviewed; Journal article, 2019)
Mathematical models for flow and reactive transport in porous media often involve non-linear, degenerate parabolic equations. Their solutions have low regularity, and therefore lower order schemes are used for the numerical ...
• #### Iterative methods for solving the Multiple Network Poroelastic Theory (MPET) model ﻿

(Master thesis, 2022-01-17)
• #### Iterative schemes for solving coupled, non-linear flow and transport in porous media ﻿

(Master thesis, 2016-12-24)
In this thesis we compare different iterative approaches for solving the non-linear, coupled multiphase flow and reactive transport in porous media. Especially, we consider two-phase flow and one a-half phase flow (modeled ...
• #### Iterative schemes for surfactant transport in porous media ﻿

(Journal article; Peer reviewed, 2021)
In this work, we consider the transport of a surfactant in variably saturated porous media. The water flow is modelled by the Richards equations and it is fully coupled with the transport equation for the surfactant. Three ...
• #### Iterative solvers for Biot model under small and large deformation ﻿

(Journal article; Peer reviewed, 2021)
We consider L-scheme and Newton-based solvers for Biot model under large deformation. The mechanical deformation follows the Saint Venant-Kirchoff constitutive law. Furthermore, the fluid compressibility is assumed to be ...
• #### Iterative solvers for poromechanics : Iterative solvers for poromechanics ﻿

(Doctoral thesis, 2019-11-22)
This thesis concerns iterative solvers for poromechanics problems. The problems in the studies have involved linear poromechanics, non-linear poromechanics, and poromechanics under large deformation. We included high order ...
• #### Iterative splitting schemes for a soft material poromechanics model ﻿

(Journal article; Peer reviewed, 2021)
We address numerical solvers for a poromechanics model particularly adapted for soft materials, as it generally respects thermodynamics principles and energy balance. Considering the multi-physics nature of the problem, ...
• #### An iterative staggered scheme for phase field brittle fracture propagation with stabilizing parameters ﻿

(Journal article; Peer reviewed, 2020)
This paper concerns the analysis and implementation of a novel iterative staggered scheme for quasi-static brittle fracture propagation models, where the fracture evolution is tracked by a phase field variable. The model ...
• #### Izu-Bonin rear-arc magmatism: Geochemical investigation of volcanoclastic material ﻿

(Master thesis, 2017-06-23)
Studied samples from the Izu Bonin rear arc show a distinct geochemical pattern that resemble the modern continental crust. In contrast to the volcanic front, samples from the Izu Bonin rear arc show enrichment of LREE ...
