På grensen til et eventyr : økonomisering av Snøhvit LNG
(Doctoral thesis; Doktorgradsavhandling, 2012-06-29)
Megaprosjekter er store investeringsprosjekter med betydelig innflytelse på samfunn, miljø og økonomi. Til tross for grundige utredninger og beregninger i forkant, presterer slike prosjekter sjelden i overenstemmelse med planene: de blir gjerne både forsinket og mye dyrere enn estimatene tilsa. Hva er det som skjer i megaprosjekter som gjør at planer om suksess blir til fortellinger om fiasko? Dette ...
Factors affecting implementation of the information exchange for traceability in food supply chains
(Doctoral thesis; Doktorgradsavhandling, 2010-11-04)
The globalisation and intensification of food production has led to food related health incidents. These incidents range from BSE in cattle to illegally high levels of dioxins in chicken feed (Carriquiry and Babcock, 2007, Caswell, 2000, Elbers et al., 2001, Fallon, 2001, Hobbs, 2004, Madec et al., 2001, Ozawa et al., 2001, Sporleder and Goldsmith, 2001). The modern consumer is increasingly ...
Bacterial flagellin : a novel adjuvant for vaccine strategies
(Doctoral thesis; Doktorgradsavhandling, 2011-10-18)
Flagellin is the principal structural protein in the locomotive organ flagellum present on flagellated bacteria, and is known to be an important evolutionarily conserved PAMP. Flagellin has been shown to bind to the PRR TLR5 which induces innate immune system responses and signaling pathways. In mammals, much focus has been placed on this protein in vaccine studies for its possible function as an ...
The effects of behaviour on the acoustic target strength of capelin (Mallotus villosus) and implications for acoustic abundance estimation
(Doctoral thesis; Doktorgradsavhandling, 2004)
The general objective of this thesis was to collect improved knowledge about the target strength (TS) of capelin (Mallotus villosus) through experimental studies, as well as to undertake adequate observations of behaviour of capelin during surveying situations, including the effect of different depth distributions and of vessel avoidance. Pre- and post-spawning capelin from the Balsfjord and the ...
Studies on the amphipod genus Metopa (Stenothoidae) : Taxonomy, Ecology, Phylogeny
(Doctoral thesis; Doktorgradsavhandling, 2011-12-19)
The Amphipod-genus Metopa is a relatively large genus, with currently 55 accepted species. This PhD thesis consists of redescriptions of 23 of these species based on typespecimens or specimens collected and identified by the original authors; this has been done to create consistent descriptions that could form a basis for a phylogenetic analysis of Metopa. For some species Scanning Electron ...
Mass cultivation of some common coldwater diatoms (Bacillariophyceae): lipids vs. growth conditions
(Doctoral thesis; Doktorgradsavhandling, 2017-02-27)
The present study was aimed at investigating northern diatoms as sustainable sources of omega-3 fatty acids widely used and now much needed in salmon aquaculture as well as ingredients to be used in nutraceuticals in the human diet. As known, fish oil is currently the main source of physiologically requisite fatty acids such as eicosapentaenoic (EPA) and docosahexaenoic acids (DHA). Due to the rapid ...
Atlantic salmon type I interferons - induction and antiviral activity

Antecedents and consequences of word of mouth - Consumer evaluation context, individualism, personality and defense of companies
(Doctoral thesis; Doktorgradsavhandling, 2015-06-03)
People often share word of mouth (WOM) with their friends, family, and colleagues, and they increasingly also share WOM with strangers through various Internet channels. Since WOM has been found to have an important impact on consumer behavior, businesses worldwide are eager to understand the intricacies of the phenomenon. In particular, businesses are interested in understanding how positive WOM ...
Why do Prices Change? An Analysis of Supply and Demand Shifts and Price Impacts in the Farmed Salmon Market
(Doctoral thesis; Doktorgradsavhandling, 2014-09-01)
Price changes in any market are essentially due to shifts in supply relative to demand. In a global market there can be several simultaneous supply and demand shifts in different geographical locations, all affecting prices to different extents. This dissertation focuses on procedures for measuring such shifts and their relative effects on prices by looking at the global market for farmed salmon ...
Antimicrobial natural products from Arctic and sub-Arcticmarine invertebrates
(Doctoral thesis; Doktorgradsavhandling, 2010-09-17)
Infectious diseases are a leading cause of death world-wide and there is a growing need for new anti-infective agents to combat multi-resistant strains of bacteria and fungi. Marine natural products are promising sources of novel antimicrobial compounds. In the present thesis, an investigation into the antimicrobial metabolites of Arctic and sub-Arctic marine invertebrate species is presented. ...
