A framework for significance analysis of gene expression data using dimension reduction methods
(Journal article; Peer reviewed, 2007)Background: The most popular methods for significance analysis on microarray data are well suited to find genes differentially expressed across predefined categories. However, identification of features that correlate ... -
A Method for Rapid Localisation of Hydrocarbon Compounds on Surfaces Using Chemical Imaging and Back-Projection
(Master thesis, 2013)Discharges of unwanted chemicals into nature is a large and complex problem. Easy, fast and reliable methods for detecting these contaminants can be viewed as a first step towards a solution. Using a hyperspectral camera ... -
A molecular dynamics study of prolate ellipsoidal nanoparticles adsorbed at liquid-vapour interfaces
(Master thesis, 2017)Nanoparticles may adsorb strongly at liquid-vapour interfaces and form layers, which may be a source for new and interesting materials. It is not fully understood how the nanoparticles adsorbed at the interface interact, ... -
A Monte Carlo Algorithm for Immiscible Two-Phase Flow in Porous Media
(Journal article; Peer reviewed, 2017)We present a Markov Chain Monte Carlo algorithm based on the Metropolis algorithm for simulation of the flow of two immiscible fluids in a porous medium under macroscopic steady-state conditions using a dynamical pore ... -
A novel compound isolated from Sclerochloa dura has anti-inflammatory effects
(Journal article; Peer reviewed, 2016)The activation of phospholipase A2 (PLA2) by means of pro-inflammatory cytokines results in the subsequent release of arachidonic acid (AA) and generates eicosanoids, which further propagate inflammation. Through cyclooxygenases ... -
A procedure to find thermodynamic equilibrium constants for CO2 and CH4 adsorption on activated carbon
(Journal article; Peer reviewed, 2015)Thermodynamic equilibrium for adsorption means that the chemical potential of gas and adsorbed phase are equal. A precise knowledge of the chemical potential is, however, often lacking, because the activity coefficient of ... -
A robust method to calculate the volume phase transition temperature (VPTT) for hydrogels and hybrids
(Journal article; Peer reviewed, 2017)Here, we report three different methods to determine the volume phase transition temperature (VPTT) of various systems including poly(N-isopropylacrylamide) (pNIPAm) based nanogels, Au nanoclusters and a combination of ... -
A simple synthetic route to methyl 3-fluoropyridine-4-carboxylate by nucleophilic aromatic substitution
(Journal article; Peer reviewed, 2006)The nitro group of methyl 3-nitropyridine-4-carboxylate (1) has successfully been replaced by fluoride anion via nucleophilic aromatic substitution to give the 3-fluoropyridine- 4-carboxylate 2. -
A study of carbonaceous aerosols in the Norwegian environment, focusing on the water-soluble organic carbon fraction
(Doctoral thesis, 2005)The aim of the present thesis was to study the carbonaceous fraction of ambient aerosols in the Norwegian environment, with a particular focus on the water-soluble carbonaceous fraction. Studies were based on bulk and ... -
A study of metal contamination in a natural ecosystem affected by smelter emissions
