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 ...
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 ...

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. ...
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 ...
