Karakterisering av antibiotikaresistens hos Escherichia coli isolert fra villrein i Norge
(Master thesis, 2015-08-06)Antibiotics revolutionized the medical industry when it was introduced due to its ability to cure infections that previously were difficult to treat. The increased use of antimicrobial agents has increased the selection ... -
Effect of ploidy and temperature on quality attributes of diploid versus triploid Atlantic salmon (Salmo salar L.), and the effect of locality (north-south) and season (spring-autumn) for quality attributes under commercial production.
(Master thesis, 2015-08-06)Fillet quality of farmed Atlantic salmon (Salmo salar L.) is affected by a broad range of pre- and post-mortem factors. The “green A licenses” in North-Norway has led increased focus on triploidisation of Atlantic salmon ... -
Effekt av svarthyllbær (Sambucus nigra) og dets innholdsstoffer på in vitro modulering av NF-kappaB-aktivitet
(Master thesis, 2015-08-06)Bær av svarthyll (Sambucus nigra) er vist å ha en immunologisk effekt, og det er antatt at et høyt innhold av polyfenoler er årsaken til dette. Det er funnet stor variasjon i innhold av polyfenoler mellom ulike sorter ... -
Optimization of Cyclotide extraction from Taraxacum officinale flowers
(Master thesis, 2015-08-06)A non-destructive protocol was created for extracting, isolating and detecting cyclotides from cultivated T. Officinale flower heads. Optimal extraction was achieved by maceration for 15 minutes in 50% MeOH and steeping ... -
A functional study of the essential amidotransferase complex MurT/CobQ in Streptococcus pneumoniae
(Master thesis, 2015-08-06)The bacterial cell wall is responsible for maintaining cell shape and gives protection from osmotic lysis caused by turgor pressure. The major component of the cell wall in Gram-positive bacteria is the structurally complex ... -
Do Polymorphisms in innate immunity genes predispose for Staphylococcus aureus bloodstream infection and affect severity and outcome?
(Master thesis, 2015-08-06)Single nucleotide polymorphisms (SNPs) in genes encoding several of the proteins involved in the human immune system may have an effect on the host’s susceptibility for invasive Staphylococcus aureus (S. aureus) infections. ... -
Reduksjon av forringelsesbakterier og ESBL-produserende Escherichia coli på kyllingfilet ved bruk av kontinuerlig UVC-lys og puls UV-lys
(Master thesis, 2015-08-06)Food safety and quality assurance of fresh poultry products involves several challenges in today’s poultry industry. Microbial requirements have created increased demands in the development of new methods for improved ... -
Virulence traits in different strains of Legionella pneumophila
(Master thesis, 2015-08-06)Different strains of Legionella are found ubiquitous in natural environments. Certain strains, such as Legionella pneumophila sero- group 1 are known as human pathogens, causing severe pneumonia. Legionella is naturally a ... -

Comparison of separate and joint modeling of bivariate response with emphasis on PLS
(Master thesis, 2015-08-05)In this thesis we have tried to find if or when multiresponse Partial Least Squares Regression(PLS2)predicts better than uniresponse PLS(PLS1). With a simulation study and analysis of variance we have investigated how ... -
A simulation study : hierarchical PLS for multi-group classification
(Master thesis, 2015-08-05)Hierarchically Ordered Taxonomic Partial Least Squares (Hot PLS) is a method for classifying data in a hierarchical structure. Since Hot PLS is a relatively new method, we want to study strengths and weaknesses of this. ... -
Effekten av forbehandling på kjernemelkpulvers funksjonelle egenskaper
(Master thesis, 2015-08-05)I dette studiet ble det undersøkt om proteinfraksjonering av kjernemelk ved hjelp av mikrofiltrering (MF) før inndamping og tørking har betydning for pulverets funksjonelle egenskaper. Et pulver med forhøyet innhold av ... -
Utvikling av proteinberiket kjøttpølse for eldre
(Master thesis, 2015-08-05)Dagens eldre er i større grad aktive, har bedre råd og helse enn tidligere. Levealderen har også økt betraktelig de siste tiårene, noe som har skapt en periode i eldres liv hvor de fremdeles er i aktivitet og bor hjemme. ... -
The immunity protein ComM; effects of overexpression in Streptococcus pneumoniae
(Master thesis, 2015-08-04)Streptococcus pneumoniae is an opportunistic Gram-positive bacterium that resides in the upper respiratory tracts of humans and can be responsible for fatal diseases such as pneumonia, bacteraemia, meningitis, and endocarditis. ... -
Beskrivende sensoriske metoder
