Food safety of salt-cured cod products : effects of salt-curing, rehydration and thermal treatmenton survival, growth and invasiveness of Listeria spp.
(Doctoral thesis; Doktorgradsavhandling, 2010-11-26)
Salt-cured and dried salt-cured (klipfish) cod (Gadus morhua L.) are highly appreciated. Salt fish and klipfish are mainly prepared by rehydration to lower the level of salt. The rehydrated cod can be used in several dishes and consumption of these products has been considered safe due to the high level of salt. The overall aim of the thesis was to study the food safety of salt-cured fish products ...
Neuronal hypoxia tolerance in diving endotherms
(Doctoral thesis; Doktorgradsavhandling, 2010-08-20)
The thesis “Neuronal hypoxia tolerance in diving endotherms” sheds light on mechanisms giving diving animals, such as the hooded seal, impressive dive capabilities of 1 hr duration down to 1000 m depth. In spite of enhanced capacity to store oxygen in their body and an ability to reduce their oxygen-consumption, these animals can resurface with blood oxygen values so low that a human being in the ...
Effect of viral RNA mimics and ISA virus infection on expression of key genes of the Atlantic salmon interferon system
(Doctoral thesis; Doktorgradsavhandling, 2008)
We have studied the innate immune responses of Atlantic salmon and how this responds to stimulation and infection by the aquatic orthomyxovirus Infectious salmon anemia virus (ISAV). This work has focused on the Type I interferon (IFN) system which is critically important in the vertebrate immune response against viral infections. As a part of this work we have studied the Atlantic salmon IFN ...
Fiskeren som forsvant? En studie av avfolking, overbefolking og endringsprosesser i norsk fiskerinæring
(Doctoral thesis; Doktorgradsavhandling, 2003-02-28)
Hva er en fisker? Dette er det sentrale spørsmålet i denne avhandlinga. Spørsmålet er utgangspunkt for å utforske endringsprosesser i fiskerinæringa, både i fortida og i samtida. På bakgrunn av dette drøfter avhandlinga hvilke oppfatninger, forståelser og beskrivelser som til enhver tid benyttes til å definere hva fiskere er i ulike sammenhenger. Undersøkelsen starter i det som kan kalles ...
Consideration set size and choice in fish consumption : the influence of attitude, knowledge, convenience, and category presentation
(Doctoral thesis; Doktorgradsavhandling, 2010-06-11)
<i>Purpose</i> – Three main objectives are defined in this thesis: 1) To determine the extent to which the nature of a consideration set affects consumer choice; 2) To investigate how consumer attitudes, knowledge, and convenience motivations affect the formation of a consideration set; and 3) To investigate how category presentation moderates the relationship between convenience motivations and ...
The potential for cooperation in shared fisheries : theory and application to Vietnam's fisheries strategy in the South China Sea
(Doctoral thesis; Doktorgradsavhandling, 2009-06-05)
Since the end of the 20th century, many shared fish stocks throughout the world have been found in extreme danger of collapse. There are many calls for cooperation in utilizing and conserving the shared fish resources including the 1982 UN Convention on the Law of the Sea and the 1995 UN Fish Stock Agreement. This study provides an important rationale for cooperation in utilizing a shared fish stock ...

Isolation and Characterisation of Bioactive Secondary Metabolites from Arctic, Marine Organisms
(Doctoral thesis; Doktorgradsavhandling, 2014-12-09)
The list of achievements in developing pharmaceuticals and other useful products originating from Nature is long, and it continues to extend. Marine bioprospecting alone has generated three novel drugs in the last four years. The continued success motivates further bioprospecting efforts in the search for utilisable products from natural sources. In this thesis, extracts of Arctic marine organisms ...
Effects of latitudinal climate conditions on quality attributes in Brassica oleracea
(Doctoral thesis; Doktorgradsavhandling, 2014-02-17)
Brassica is a genus of plants that includes vegetables that are widely used for human consumption and contain high levels of health-promoting compounds. These vegetables are grown in large parts of the world, and the environmental conditions where they are cultivated can affect several quality attributes. The research presented in this thesis examined how variation in growth conditions with ...
Induction of Atlantic salmon type I interferon and antagonism by infectious pancreatic necrosis virus
(Doctoral thesis; Doktorgradsavhandling, 2014-04-08)
Viral infections are a leading cause of mortality in the farming of Atlantic salmon in Norway. Viral outbreaks cause heavy losses each year, and one of the most predominant viral diseases is infectious pancreatic necrosis (IPN). The virus causing this disease, the infectious pancreatic necrosis virus (IPNV), belongs to the Birnaviridae family of viruses with a double-stranded RNA (dsRNA) genome. ...
