Safe production of farmed Atlantic salmon (Salmo salar)
(Research report, 2010)This work contains a review of the undesirable substances that may be introduced as contaminants of natural and malicious origin, and of emerging hazards, in the production chain of farmed salmon,from ova to packed fillet. ... -
Safe, selfish state-independent mobbing behaviour in the cooperatively breeding apostlebird (Struthidea cinerea)
(Master thesis, 2011)In the last few decades stochastic dynamic modeling (SDM) has been used to explore adaptive state-dependent strategies in a whole host of different theoretical problems in behavioural ecology, with considerable success. ... -
Safety aspects of maritime hydrogen fuel from local sorption-enhanced ethanol steam reforming
(Master thesis, 2020)Damp reformering av etanol med integrert CO2-fangst, såkalt sorption-enhanced ethanol steam reforming (SEESR), har potensiale til å effektivt konvertere etanol til hydrogen. I denne masteroppgaven vurderes sikkerhetsaspekter ... -
Safety in numbers: multiple occurrences of highly similar homologs among Azotobacter vinelandii carbohydrate metabolism proteins probably confer adaptive benefits
(Journal article; Peer reviewed, 2014)Background Gene duplication and horizontal gene transfer are common processes in bacterial and archaeal genomes, and are generally assumed to result in either diversification or loss of the redundant gene copies. However, ... -
SAG-FW Welding of C90 Riser Steel Connectors
(Master thesis, 2012)Weld simulations have been conducted on a C90 quenched tempered steel used in offshore riser systems, in order to investigate the possibility of introducing an effective solid state weld procedure. As a secondary objective, ... -
Salinity acclimation strategies for nitrifying bioreactors in recirculating aquaculture systems
(Doctoral theses at NTNU;2021:33, Doctoral thesis, 2021)The demand for seafood is rising like never before, and unsustainable fishing has depleted the oceans. Recirculating aquaculture systems (RAS) can present a sustainable solution by producing seafood in land-based systems ... -
Salinity Acclimation Strategies in Nitrifying Bioreactors
(Peer reviewed; Journal article, 2022)Several industries, including aquaculture, produce effluents with high or varying salt concentrations. The treatment of such effluents by the biological nitrification process can be challenging, as the microbes performing ... -
Salinity as a driver for microbial community structure in reactors for nitrification and anammox
(Doctoral theses at NTNU;2016:365, Doctoral thesis, 2016)The removal of nitrogen from wastewater has become an important part of the overall treatment process due to the significant impact of nitrogen compounds (NH4–N, NOx–N) on the environment and the more stringent legislation ... -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Journal article; Peer reviewed, 2019)Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ... -
Salmon louse infestation in wild brown trout populations generates multi-modal mixture distributions
(Peer reviewed; Journal article, 2020)For successful evaluation of the overall effects of salmon louse infestation on brown trout population dynamics, it is crucial to have a realistic understanding of how lice infestation distributions are generated and how ... -
Salmonid fishes in a changing climate : the winter challenge
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:199, Doctoral thesis, 2005)In the present thesis, winter mortality was linked to levels of stored energy by a field study from a northern Atlantic salmon population where population frequency distributions for specific somatic energy were compared ... -
Salt clogging during supercritical CO2 injection into a downscaled borehole model
(Journal article; Peer reviewed, 2019)Injection of CO2 into saline storage aquifers is often accompanied by drying of the formation water and salt precipitation. Subsequent salt clogging of a well bore and the near wellbore rock matrix may lead to injectivity ... -
Salt efflorescence in historic wooden buildings
(Peer reviewed; Journal article, 2016)Efflorescence and subflorescence are frequent phenomena occurring in buildings of porous inorganic materials such as bricks, stone, and concrete. Since the above phenomena have detrimental effects, they were the subject ... -
Salt-inducible kinase 1 (SIK1) is induced by gastrin and inhibits migration of gastric adenocarcinoma cells
(Journal article; Peer reviewed, 2014-11-10)Salt-inducible kinase 1 (SIK1/Snf1lk) belongs to the AMP-activated protein kinase (AMPK) family of kinases, all of which play major roles in regulating metabolism and cell growth. Recent studies have shown that reduced ... -
Salting of Muscle Foods: Effects of processing conditions and sodium reduction
(Doctoral thesis at NTNU;2014:335, Doctoral thesis, 2014)The present thesis aims at investigating (i) salt distribution in the lean fish- and meat minces, (ii) the effect of different ions on the extractability of salt soluble proteins, and (iii) the possibility to decrease salt ... -
A salty start: Brackish water start-up as a microbial management strategy for nitrifying bioreactors with variable salinity
(Peer reviewed; Journal article, 2020)Nitrifying biofilms developed in brackish water are reported to be more robust to salinity changes than freshwater biofilms. This makes them a promising strategy for water treatment systems with variable salinity, such as ... -

Samanlikning av ferroelektriske eigenskapar i PbZrxTi1-xO3, BaTiO3 og [N(CH3)4][FeBrCl3]
(Bachelor thesis, 2023)Denne teksten skal sjå på fordelane og ulempene ved å bruke supermolekylære ferroelektriske materialer som erstatning for intermolekylære ferroelektriske materialer, som bly zirkonat titanat (PZT) og barium titanat (BTO). ... -
Samanlikning og haldbarheit av PT-INR i EDTA- og citrat-plasma
(Bachelor thesis, 2022)Samandrag Føremålet med oppgåva var å undersøke om EDTA-plasma kan nyttast alternativt til citrat-plasma ved måling av PT-INR, samt verifisere haldbarheita til prøvemateriala i romtemperatur og ved 2-8 ℃. Det blei utført ... -
Sammenhengen mellom anti-FXa-aktiviteten i plasma og konsentrasjonen av legemidler som hemmer FXa
