Safety and security of autonomous vessels. Based on the Yara Birkeland project
(Master thesis, 2020-05-05)Yara Birkeland will be the world’s first fully electric and autonomous container vessel with zero emission. It is being developed by Kongsberg and Yara. This is one of the autonomous projects ongoing in the maritime ... -
Safety assessment of the functional feed additive phenylcapsaicin in a commercial broiler diet
(Journal article; Peer reviewed, 2023)Introduction: Intestinal colonisation of Salmonella is a major concern in the poultry industry, and a low dose of the high-purity synthetic capsaicin analogue phenylcapsaicin (PheCap) has the potential to be a phytobiotic ... -
The SailBuoy remotely-controlled unmanned vessel: Measurements of near surface temperature, salinity and oxygen concentration in the Northern Gulf of Mexico
(Peer reviewed; Journal article, 2014-09)An experimental deployment of a new type of unmanned vessel is presented. The Christian Michelsen Research SailBuoy, a remotely-controlled surface vehicle, sampled near-surface properties during a two-month mission in the ... -
Salamonid alphavirus (SAV) - genetic characterisation of a new subtype, SAV3, and implementation of a novel diagnostic method
(Doctoral thesis, 2006-12-13) -
Salinity Gradient Energy from Expansion and Contraction of Poly(allylamine hydrochloride) Hydrogels
(Peer reviewed; Journal article, 2018-06-08)Salinity gradients exhibit a great potential for production of renewable energy. Several techniques such as pressure-retarded osmosis and reverse electrodialysis have been employed to extract this energy. Unfortunately, ... -
Salmon lice as models for understanding life history evolution of parasites under intensive farming
(Doctoral thesis, 2017-06-20)Human activities are drastically changing ecological conditions for living organisms and this leads to evolutionary changes. One example is the appearance and spread of resistance against drugs and antibiotics, but we also ... -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Peer reviewed; Journal article, 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 lice survive the straight shooter: A commercial scale sea cage trial of laser delousing
(Journal article; Peer reviewed, 2020)Ectoparasitic salmon louse (Lepeophtheirus salmonis) infestations are costly for Atlantic salmon (Salmo salar) farmers in Norway. As a result, there is a strong desire for solutions to prevent and control infestations, and ... -
Salmon louse (Lepeophtheirus salmonis) transcriptomes during post molting maturation and egg production, revealed using EST-sequencing and microarray analysis
(Peer reviewed; Journal article, 2008-03-10)Background Lepeophtheirus salmonis is an ectoparasitic copepod feeding on skin, mucus and blood from salmonid hosts. Initial analysis of EST sequences from pre adult and adult stages of L. salmonis revealed a large proportion ... -
The salmon louse genome may be much larger than sequencing suggests
(Journal article; Peer reviewed, 2022)The genome size of organisms impacts their evolution and biology and is often assumed to be characteristic of a species. Here we present the first published estimates of genome size of the ecologically and economically ... -
The salmon louse genome: Copepod features and parasitic adaptations
(Journal article; Peer reviewed, 2021)Copepods encompass numerous ecological roles including parasites, detrivores and phytoplankton grazers. Nonetheless, copepod genome assemblies remain scarce. Lepeophtheirus salmonis is an economically and ecologically ... -
Salmon louse labial gland enzymes: implications for host settlement and immune modulation
(Journal article; Peer reviewed, 2024)Salmon louse (Lepeophtheirus salmonis) is a skin- and blood-feeding ectoparasite, infesting salmonids. While feeding, labial gland proteins from the salmon louse may be deposited on the Atlantic salmon (Salmo salar) skin. ... -
The salmon louse larval black box: evaluating fecundity and enumerating planktonic stages with an aquaculture management perspective
(Doctoral thesis, 2022-06-17)Modern salmon aquaculture began in 1970 with the innovation of at-sea fish pens which precipitated a rapid growth in production. The expansion of the industry and increased number of farmed fish concentrated within the ... -
The salmon louse Lepeophtheirus salmonis (Copepoda: Caligidae) life cycle has only two chalimus stages
(Peer reviewed; Journal article, 2013-09-12)Each year the salmon louse (Lepeophtheirus salmonis Krøyer, 1838) causes multi-million dollar commercial losses to the salmon farming industry world-wide, and strict lice control regimes have been put in place to reduce ... -
Salmonid fish: model organisms to study cardiovascular morphogenesis in conjoined twins?
(Peer reviewed; Journal article, 2016-07-16)Background: There is a gap in knowledge regarding the cardiovascular system in fish conjoined twins, and regarding the cardiovascular morphogenesis of conjoined twins in general. We examined the cardiovascular system in a ... -

Salt decollement and rift inheritance controls on crustal deformation in orogens
(Journal article; Peer reviewed, 2019-09)We investigate the factors that control the shortening distribution and its evolution through time in orogenic belts using numerical models. We present self‐consistent high‐resolution numerical models that simulate the ... -
Sammenheng mellom løsningsegenskaper, grenseflatespenning og retensjon for et kommersielt surfaktantsystem
(Master thesis, 2014-05-30)For å oppnå en suksessfull surfaktantflømming i økt oljeutvinning, ønsker man generelt å injisere en surfaktantløsning som har gode løsningsegenskaper, reduserer grenseflatespenning mellom vann og olje effektivt, og som ... -
Sammenhenger mellom koder, matroider, grafer og simplisielle komplekser
