Comparing species-temperature relationships of arctic-alpine plants among three altitudinal transects in Svalbard
(Master thesis, 2008)Broad scale data has normally been used to predict vascular plant species responses to global climate change. The aim of this study is to investigate to what extent a high sampling resolution reveals local variations among ... -
Comparing the adsorption of methyl orange and malachite green on similar yet distinct polyamide microplastics: Uncovering hydrogen bond interactions
(Journal article; Peer reviewed, 2023)Microplastics (MPs) and dye pollutants are widespread in aquatic environments. Here, the adsorption characteristics of anionic dye methyl orange (MO) and cationic dye malachite green (MG) on polyamide 6 (PA6) and polyamide ... -
Comparing the effects of solar-related and terrestrial drivers on the northern polar vortex
(Journal article; Peer reviewed, 2020)Northern polar vortex experiences significant variability during Arctic winter. Solar activity contributes to this variability via solar irradiance and energetic particle precipitation. Recent studies have found that ... -
Comparing the intrinsic dynamics of multiple protein structures using elastic network models
(Peer reviewed; Journal article, 2015-05)Background: Elastic network models (ENMs) are based on the simple idea that a protein can be described as a set of particles connected by springs, which can then be used to describe its intrinsic flexibility using, for ... -
Comparing the transcriptomes of embryos from domesticated and wild Atlantic salmon (Salmo salar L.) stocks and examining factors that influence heritability of gene expression
(Peer reviewed; Journal article, 2016-03-17)Background: Due to selective breeding, domesticated and wild Atlantic salmon are genetically diverged, which raises concerns about farmed escapees having the potential to alter the genetic composition of wild populations ... -
Comparing Three Approaches to the Inducing Source Setting for the Ground Electromagnetic Field Modeling due to Space Weather Events
(Journal article; Peer reviewed, 2020)Ground-based technological systems, such as power grids, can be affected by geomagnetically induced currents (GIC) during geomagnetic storms and magnetospheric substorms. This motivates the necessity to numerically simulate ... -
Comparison between Air Temperature and Land Surface Temperature for the City of São Paulo, Brazil
(Journal article; Peer reviewed, 2022)This study aims to identify the relationship between changes in temperature regarding urbanization processes and seasonality in the city of São Paulo, located in the Tropic of Capricorn. The land surface temperature (LST) ... -
Comparison between instrumental variable and mediation-based methods for reconstructing causal gene networks in yeast
(Journal article; Peer reviewed, 2021)Causal gene networks model the flow of information within a cell. Reconstructing causal networks from omics data is challenging because correlation does not imply causation. When genomics and transcriptomics data from a ... -
Comparison between precipitation estimates of ground-based weather radar composites and GPM’s DPR rainfall product over Germany
(Journal article; Peer reviewed, 2020)We compare more than three years (between 2014 and 2018) of precipitation estimates over Germany from the Dual-frequency Precipitation Radar (DPR) operating on the core satellite of the Global Precipitation Mission (GPM) ... -
A comparison of abundance, distribution and behavior of Northeast Atlantic mackerel (Scomber scombrus L.) during curved and straight forward trawling.
(Master thesis, 2016-06-01)Northeast Atlantic Mackerel (Scomber scombrus) is one of the largest and economically most valuable fish stocks in the world. However, due to a large area of distribution, low acoustic backscatter and highly dynamic and ... -
Comparison of anadromous and landlocked Atlantic salmon genomes reveals signatures of parallel and relaxed selection across the Northern Hemisphere
(Journal article; Peer reviewed, 2020)Most Atlantic salmon (Salmo salar L.) populations follow an anadromous life cycle, spending early life in freshwater, migrating to the sea for feeding, and returning to rivers to spawn. At the end of the last ice age ~10,000 ... -
A comparison of analytical approaches to investigate associations for accelerometry-derived physical activity spectra with health and developmental outcomes in children
(Journal article; Peer reviewed, 2021)The use of high-resolution physical activity intensity spectra obtained from accelerometry can improve knowledge of associations with health and development beyond the use of traditional summary measures of intensity. The ... -
A comparison of ancient deltaic shoreline progradation with modern deltaic progradation rates: Unravelling the temporal structure of the shallow-marine Blackhawk Formation, Upper Cretaceous Western Interior Seaway, USA
(Journal article; Peer reviewed, 2022)Understanding how sedimentary rocks represent time is one of the significant challenges in sedimentology. Sedimentation rates retrieved from vertical sections are strongly timescale dependent, which means that we cannot ... -
A Comparison of Anthropometric Measures for Assessing the Association between Body Size and Risk of Chronic Low Back Pain: TheHUNT Study
(Peer reviewed; Journal article, 2015-10-27)Background: Previous work indicates that overweight and obese individuals carry an increased risk of experiencing chronic low back pain (LBP). It is not known, however, how the association with body size depends on the ... -
Comparison of burning velocity differences in a numerical explosion simulator
(Master thesis, 2014-06-02)A verification study of the two flame models in the numerical explosion simulation tool FLACS has been conducted. The beta flame model, and the SIF flame model has been tested in a 1D-channel at different time step sizes. ... -
Comparison of calibration models for rapid prediction of lignin content in lignocellulosic biomass based on infrared and near-infrared spectroscopy
(Journal article; Peer reviewed, 2022)Lignocellulosic biomass has great potential as a renewable energy source due to abundance both as vegetation and in residues from agriculture and forestry. It can be utilized for biofuels and for value-added chemicals and ... -
Comparison of diet composition, feeding, growth and health of lumpfish (Cyclopterus lumpus L.) fed either feed blocks or pelleted commercial feed
(Peer reviewed; Journal article, 2019)Two duplicate groups of individually tagged lumpfish (mean initial weight: 21.5 ± 3.2 g) were fed either a commercially available lumpfish feed or feed blocks for a period of 123 days. The aim was to evaluate and compare ... -
