Quantifying vertical profiles of biochemical traits for forest plantation species using advanced remote sensing approaches
(Peer reviewed; Journal article, 2020)Biochemical traits in forest vegetation are key indicators of leaf physiological processes, specifically photosynthetic and other photochemical light pathways, and are critical to the quantification of the terrestrial ... -
Quantifying vulnerability to flooding induced by climate change: The case of Verdal, Norway
(Journal article; Peer reviewed, 2014)The article presents a methodology for the measurement of exposure and social vulnerability to hazards at local level. Using the small town of Verdal in central Norway as a case study, the authors examine its vulnerability ... -
Quantile based modeling of diurnal temperature range with the five-parameter lambda distribution
(Peer reviewed; Journal article, 2022)Diurnal temperature range is an important variable in climate science that canprovide information regarding climate variability and climate change. Changesindiurnaltemperaturerangecanhaveimplicationsforhydrology,humanhealthand ... -
Quantitation of linear and branched perfluoroalkane sulfonic acids (PFSAs) in women and infants during pregnancy and lactation
(Peer reviewed; Journal article, 2021)Background - Per- and polyfluoroalkyl substances (PFAS) are associated with negative health effects, and exposure during fetal life and infancy are of concern. A subgroup of PFAS, linear and branched perfluoroalkane sulfonic ... -
Quantitative (S)TEM analysis of intermediate band solar cell materials
(Master thesis, 2011)In this thesis the strain properties of two InAs/GaAs quantum dot intermediate band solar cell materials have been explored. Both samples were thin films grown on a (100) GaAs substrate. The quantum dot material was InAs, ... -
Quantitative 3-D colocalization analysis as a tool to study the intracellular trafficking and dissociation of pDNA-chitosan polyplexes
(Journal article; Peer reviewed, 2012)Multichannel microscopy is frequently used to study intermolecular interactions and spatial relationships between biomolecules and organelles or vesicles in cells. Based on multichannel images, quantitative colocalization ... -
Quantitative 31P HR-MAS MR spectroscopy for detection of response to PI3K/mTOR inhibition in breast cancer xenografts
(Journal article; Peer reviewed, 2014)PURPOSE: Phospholipid metabolites are of importance in cancer studies, and have been suggested as candidate metabolic biomarkers for response to targeted anticancer drugs. The purpose of this study was to develop a ... -
Quantitative 3D Imaging and Metrology Using Coherent X-ray Scattering
(Doctoral theses at NTNU;2017:300, Doctoral thesis, 2017)This thesis has focused on exploring methods of using coherent X-ray scattering at synchrotron sources. New imaging techniques using coherent X-ray scattering have been investigated, and it has been discussed how limitations ... -
Quantitative 3D X-ray Imaging of Densification, Delamination and Fracture in a Micro-Composite under Compression
(Journal article; Peer reviewed, 2015)Phase-contrast three-dimensional tomograms showing in unprecedented detail the mechanical response of a micro-composite subjected to a mechanical compression test are reported. The X-ray ptychography images reveal the ... -
