Acoustic Delicing of Atlantic Salmon (Salmo salar): Fish Welfare and Salmon Lice (Lepeophtheirus salmonis) Dynamics
(Journal article; Peer reviewed, 2022)Acoustic lice treatment (AcuLice) is a newly developed system, which uses a composite acoustic sound image with low-frequency sound to remove salmon lice (Lepeophtheirus salmonis) from Atlantic salmon (Salmo salar). This ... -
Acoustic measurement of liquid density with applications for mass measurement of oil
(Doctoral thesis, 2007-11-23) -
Acoustic Methods for Obtaining the Pressure Reflection Coefficient from a Buffer Rod Based Measurement Cell
(Peer reviewed; Journal article, 2008-08-08)The known acoustic methods for obtaining the pressure reflection coefficient from a buffer rod based measurement cell are presented, along with 2 new generic approaches for measuring the pressure reflection coefficient ... -
Acoustic Propagation Underneath the Arctic Sea-ice
(Doctoral thesis, 2018-10-04)The main objective of this project is to study the effect of sea-ice on underwater acoustic wave propagation. Three main parameters define how acoustic waves react to the presence of seaice: (i) the roughness of the underside ... -
Acoustic Signatures of Gas Hydrates - Observations and Modelling
(Master thesis, 2017-08-08)Interpretation of a Bottom Simulating Reflector (BSR) associated with gas hydrate accumulations in seismic, depend on gas hydrate saturation and distribution in pore voids. The BSR cannot predict gas hydrate saturation or ... -
Acoustic telemetry predation sensors reveal the tribulations of Atlantic salmon (Salmo salar) smolts migrating through lakes
(Journal article; Peer reviewed, 2021)Smolt migration through lakes is hazardous, as the predation pressure can be extreme and the hydrology a great contrast to that of a riverine area. However, the mechanisms yielding these challenges have been scarcely ... -
Acoustic waveform inversion for ocean turbulence
(Peer reviewed; Journal article, 2017)The seismic oceanography method is based on extracting and stacking the low-frequency acoustic energy scattered by the ocean heterogeneity. However, a good understanding on how this acoustic wavefield is affected by physical ... -
Actin N-terminal acetylation impacts cell adhesion and invasion
(Master thesis, 2019-12-14) -
Actions on sustainable food production and consumption for the post-2020 global biodiversity framework
(Journal article; Peer reviewed, 2021)Current food production and consumption trends are inconsistent with the Convention on Biological Diversity’s 2050 vision of living in harmony with nature. Here, we examine how, and under what conditions, the post-2020 ... -
Activation mechanism and activity of globupain, a thermostable C11 protease from the Arctic Mid-Ocean Ridge hydrothermal system
(Journal article; Peer reviewed, 2023)Deep-sea hydrothermal vents offer unique habitats for heat tolerant enzymes with potential new enzymatic properties. Here, we present the novel C11 protease globupain, which was prospected from a metagenome-assembled genome ... -
Activation of Atlantic cod (Gadus morhua) retinoid X receptors by organic tin compounds
(Master thesis, 2023-06-02) -
Active and integrated management of water resources throughout CO2 capture and sequestration operations
(Peer reviewed; Journal article, 2011)Most projected climate change mitigation strategies will require a significant expansion of CO2 Capture and Sequestration (CCS) in the next two decades. Four major categories of challenges are being actively researched: ... -
Active Smarter Kids (ASK): Rationale and design of a cluster-randomized controlled trial investigating the effects of daily physical activity on children's academic performance and risk factors for non-communicable diseases
(Peer reviewed; Journal article, 2015-07-28)Background Evidence is emerging from school-based studies that physical activity might favorably affect children’s academic performance. However, there is a need for high-quality studies to support this. Therefore, the ... -
Acute effects of gas supersaturation on Atlantic salmon smolt in two Norwegian rivers
(Journal article; Peer reviewed, 2020)Total dissolved gas (TDG) supersaturation downstream of hydropower plants may cause gas bubble disease (GBD) and harmful effects in fish. Little is known about tolerance levels of TDG supersaturation on Atlantic salmon ... -
Acyclic, star, and injective colouring: bounding the diameter∗
(Journal article; Peer reviewed, 2022)We examine the effect of bounding the diameter for a number of natural and well-studied variants of the COLOURING problem. A colouring is acyclic, star, or injective if any two colour classes induce a forest, star forest ... -
Acylated Flavone O-Glucuronides from the Aerial Parts of Nepeta curviflora
(Journal article; Peer reviewed, 2020)Nepeta curviflora Boiss. (Syrian catnip) is native to the Middle East. This medicinal plant is commonly used against nervous disorders, rheumatic pains, and high blood pressure. Herbal infusions prepared from various Nepeta ... -
Adaptation of anemonefish to their host anemones: From Genetics to Physiology
(Doctoral thesis, 2020-02-21)The mutualism between anemonefish and anemones can be studied in terms of permanent or temporary adaptation of fish toward their host anemones. This thesis explores this theme, and aims to test (1) Whether a mutual ... -
Adaptation of unbiased stereological methods to study theeffects of feed composition on the morphometrics of the different layers of the digestive tract of juvenile Atlantic cod (Gadus morhua L.)
(Master thesis, 2004)Juveniles of Atlantic cod (Gadus morhua L.) were fed food, containing different compositions of macro-nutrients (proteins, fat and carbohydrates). The aims of this study were to evaluate the use of unbiased stereology to ... -
