Sequestration of Carbon in Saline Aquifers Mathematical and Numerical Analysis
(Doctoral thesis, 2004-04-30)The work in this thesis focuses equally on two main topics. The first of these subjects deals with development of criteria for monotonicity of con- trol volume methods. These methods are important and frequently used for ... -
Serum fatty acid and lipoprotein subclass concentrations and their associations in prepubertal healthy Norwegian children
(Peer reviewed; Journal article, 2016-03)Introduction The lipid metabolism is one of the most important and complex processes in the body. Serum concentrations of 18 fatty acids (FAs) and 24 lipoprotein features, i.e. concentrations of lipoprotein main and ... -
Set in stones: the influence of long-term environmental changes on Northeast Arctic cod viewed through the analysis of otoliths
(Doctoral thesis, 2021-03-23)The living conditions of marine ecosystems are currently changing rapidly under the influence of human exploitation and contributions to climate change, especially in high latitude regions such as the Arctic. Predicting ... -
Setting reference levels and limits for good ecological condition in terrestrial ecosystems – Insights from a case study based on the IBECA approach
(Journal article; Peer reviewed, 2020-09)Effective evidence-based nature conservation and habitat management relies on developing and refining our methodological toolbox for detecting critical ecological changes at an early stage. This requires not only optimizing ... -
Setup and Integration of the Readout Electronics for the Pixel Layers of the New ALICE FoCal Detector
(Master thesis, 2022-03-23) -
A setup for electrical tests of ATLAS SCT barrel modules
(Master thesis, 2003)The ATLAS SemiConductor Tracker (SCT) is part of the inner detector in the ATLAS detector at the LHC complex at CERN. SCT will consist of a system of silicon strip detectors with digital readout, reading out space point ... -
A setup for electronic tests of ATLAS silicon strip detectors
(Master thesis, 2001) -
The Seven Sisters Hydrothermal System: First Record of Shallow Hybrid Mineralization Hosted in Mafic Volcaniclasts on the Arctic Mid-Ocean Ridge
(Journal article; Peer reviewed, 2020)We document the discovery of an active, shallow, seafloor hydrothermal system (known as the Seven Sisters Vent Field) hosted in mafic volcaniclasts at a mid-ocean ridge setting. The vent field is located at the southern ... -
Severe and localized GNSS scintillation at the poleward edge of the nightside auroral oval during intense substorm aurora
(Peer reviewed; Journal article, 2015-12)In this paper we study how GPS, GLONASS, and Galileo navigation signals are compromised by strong irregularities causing severe phase scintillation (σϕ>1) in the nightside high-latitude ionosphere during a substorm on 3 ... -
Severe mesoscale weather events over the Nordic Seas: Numerical modelling and sensitivity experiments
(Doctoral thesis, 2011-06-22)The Nordic seas region, due to its unique geographical and climatological conditions, experiences a number of adverse mesoscale weather events that have proven fatal for human activities in the area. Most of these weather ... -
Severi varieties on blow-ups of the symmetric square of an elliptic curve
(Journal article; Peer reviewed, 2023)We prove that certain Severi varieties of nodal curves of positive genus on general blow-ups of the twofold symmetric product of a general elliptic curve are nonempty and smooth of the expected dimension. This result, ... -
Sewage-based surveillance shows presence of Klebsiella pneumoniae resistant against last resort antibiotics in the population in Bergen, Norway
(Journal article; Peer reviewed, 2022)The aim of this study was to understand the prevalence of antibiotic resistance in Klebsiella pneumoniae present in the population in Bergen city, Norway using city-scale sewage-based surveillance, as well as the potential ... -
Sex differences in the early life stages of the salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae)
(Journal article; Peer reviewed, 2022)Salmon lice are ectoparasites on salmonids and feed on blood, mucus, and skin from their hosts. This causes high annual costs for treatment and control for the aquaculture industry. Salmon lice have a life cycle consisting ... -
Sex differentiation in Atlantic cod (Gadus morhua L.): morphological and gene expression studies
(Peer reviewed; Journal article, 2012-06-18)Background: In differentiated gonochoristic species, a bipotential gonad develops into an ovary or testis during sex differentiation. Knowledge about this process is necessary to improve methods for masculinizing genetically ... -
Sexual dimorphism in the familial aggregation of tinnitus
(Journal article; Peer reviewed, 2020-11)Twin and adoption studies point towards a genetic contribution to tinnitus; however, how the genetic risk applies to different forms of tinnitus is poorly understood. Here, we perform a familial aggregation study and ... -
Sexual dimorphism of drumming muscles in European hake (Merluccius merluccius)
(Peer reviewed; Journal article, 2010)Dissections of mature and non-mature European hake males and females (N = 142) collected in waters off the western coast of Norway and in the Bay of Biscay (France) in 2004–2006 demonstrate for the first time that this ... -
Sexual size dimorphism of bark and ambrosia beetles
(Master thesis, 2016-06-01)Size is a defining feature of an animal and is a result of counteracting forces of selection, and studying size and SSD can reveal what drives selection of body size in a given direction. Scolytinae and Platypodinae are ... -
Sex‑Specifc Diferences in Mortality of Patients with a History of Bariatric Surgery: a Nation‑Wide Population‑Based Study
(Journal article; Peer reviewed, 2022)Purpose Bariatric surgery reduces mortality in patients with severe obesity and is predominantly performed in women. Therefore, an analysis of sex-specific differences after bariatric surgery in a population-based dataset ... -
sFDvent: A global trait database for deep‐sea hydrothermal‐vent fauna
