Application of Bayesian calibration for propagation of uncertainty in dynamic models
(PhD Thesis;2010:8, Doctoral thesis, 2010)The thesis is about quantification of uncertainties in complex models. Models are built to describe, explain or predict a real world outcome. It is well known that models are related with uncertainty, and that uncertainties ... -
A study of mechanisms involved in the pathogenicity of Enterococcus faecalis by DNA microarrays
(PhD Thesis;2010:54, Doctoral thesis, 2010)Traditionally considered a harmless commensal of the mammalian gastrointestinal tract, Enterococcus faecalis now rank among the leading causes of nosocomial infections worldwide. Several genetic determinants enhancing the ... -
Lactobacillus sakei metabolism and diversity
(PhD Thesis;2010:21, Doctoral thesis, 2010)Lactic acid bacteria are associated with food fermentation, acidification and preservation. Lactobacillus sakei is an industrially important species mainly due to its ability to ferment and preserve meat. It is used as ... -
Molecular mechanisms of pneumococcal fratricide
(PhD Thesis;2010:13, Doctoral thesis, 2010)The bacterium Streptococcus pneumoniae is endowed with the ability to take up naked DNA from the surroundings and recombine this DNA into the chromosome. This property, termed competence for natural genetic transformation, ... -
Natural genetic transformation: development of a new genetic tool for Streptococcus thermophilus
(PhD Thesis;2010:16, Doctoral thesis, 2010)Lactic acid bacteria (LAB) have been used in fermentation of foods for hundreds or even thousands of years. During the last decade the genome sequences of a number of commercially important LAB species and strains have ... -
An explorative study of Enterococcus faecalis transcriptional responses to infection-relevant growth environments
(PhD Thesis;2010:10, Doctoral thesis, 2010)Enterococcus faecalis is commonly found in the gastrointestinal tract of humans. It is also an opportunistic pathogen and one of the leading causes of nosocomial infections worldwide. The treatment of E. faecalis infections ... -

(PhD Thesis;2010:03, Doctoral thesis, 2010)This thesis is a part of the research project ‘‘Low energy products and consumer preferences”, financed by the Research Council of Norway (NFR) through Grant 167928/I10. The thesis is based on three experiments. Consumers’ ... -
Vekst av patogene mikroorganismer ved ulike temperaturer
(Master thesis, 2010-10-22)Oppgaven er en del av forskningsprosjektet ”Bedre mattrygghet i hjemmet gjennom risikoanalyse av forbrukerhåndtering av mat og evaluering av risikoreduserende tiltak”, et samarbeid mellom Nofima Mat og SIFO (statens ... -
Interaksjoner mellom kitooligosakkarider og kitinase B fra Serratia marcescens studert ved overflateplasmonresonans og isotermisk titreringskalorimetri.
(Master thesis, 2010-10-29)Hovedmålet i dette studiet var å sammenligne bruk av isotermisk titreringskalorimetri (ITC) og overflateplasmonresonans (SPR) ved bindingsstudier mellom KitinaseB(ChiB) og kitooligosakkarider (KOS) av ulik lengde. Det ... -
Overlevelse og vekst av matrelaterte bakterier på antimikrobielle overflater
(Master thesis, 2010-10-29)Det er de siste årene kommet en rekke produkter på markedet med påståtte antimikrobielle egenskaper, der antimikrobielle forbindelser er inkorporert i eller ligger som belegg utenpå produktet. To slike antimikrobielle ... -
A BN-PAGE approach to investigation of protein-protein interactions in square array assembly and potential AQP4 binding partners
(Master thesis, 2010-10-29)ABSTRACT Aquaporin 4 (AQP4) is a membrane protein, and also the main water channel in the brain. AQP4 is distributed with highest density in the perivascular end-feet membrane of astrocytes, which are supporting cells of ... -
Determination of volatile organic compounds (VOC) in work-room air using direct-reading PTR-MS and traditional air sampling methodologies
(Master thesis, 2010-10-29)PTR-MS was evaluated up against traditional air sampling methodologies by choosing compounds that were tested by injecting a known amount of reference compounds into the test chamber to create artificial atmospheres. ... -
Proteinanalyse ved hjelp av massespektrometri
(Master thesis, 2010-11-16)Hovedmålet med oppgaven var å teste ulike prosedyrer for fraksjonering av celler. Ved å identifisere og kvantifisere proteinuttrykk ved hjelp av LC-MS (væskekromatografi-massespektrometri) som metode kan man bestemme ... -
Regulation of denitrification in the genus Thauera; response pattern in the transition from oxic to anoxic environment, life on the energetic edge
(Master thesis, 2010-11-16)Denitrification is a taxonomically widespread process used by more than 60 different genera of bacteria including archaea and some fungi, where nitrate is reduced to dinitrogen gas (N2) by four enzymes; nitrate reductase ... -
