Identification of genes affecting alginate biosynthesis in Pseudomonas fluorescens by screening a transposon insertion library.
(Journal article; Peer reviewed, 2017)BACKGROUND: Polysaccharides often are necessary components of bacterial biofilms and capsules. Production of these biopolymers constitutes a drain on key components in the central carbon metabolism, but so far little is ... -
Identification of Marine Organisms using Chemotaxonomy and Hyperspectral Imaging
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:292, Doctoral thesis, 2013)In this study, pigment composition in marine organisms has been investigated for different purposes. The absorption spectra of pigments from a given organism give us an optical fingerprint for that particular organism when ... -
Identification of novel cyanoacrylate monomers for use in nanoparticle drug delivery systems prepared by miniemulsion polymerisation – A multistep screening approach
(Peer reviewed; Journal article, 2022)Poly (alkyl cyanoacrylate) (PACA) polymeric nanoparticles (NPs) are promising drug carriers in drug delivery. However, the selection of commercially available alkyl cyanoacrylate (ACA) monomers is limited, because most ... -
Identification of Novel Genes associated with Rheumatoid Arthritis using Differential Gene Co-Expression Analysis
(Master thesis, 2018)Large RNA-Seq and DNA microarray data sets have enabled the study of relationships between genes through co-expression analyses. Changes in gene co-expression patterns are often related to changes in biological function, ... -
Identification of NRF2 binding sites in metastatic breast cancer cells by ChIP-Seq
(Master thesis, 2021)Background: Nuclear factor erythroid 2-related factor 2 (NRF2) is a transcription factor that is indicated to be an important component in promoting cancer metastasis. Accordingly, the role of the transcription factor has ... -
Identification of Potential Cellular Pathways Involved in Mediating the Rapid Bactericidal Effects of the Novel β-clamp-targeting Antimicrobial Peptide Betatide
(Master thesis, 2023)Økende antimikrobiell resistens, samt redusert utvikling av nye antibiotika, har ført til en global utfordring som innebærer en stor økonomisk og sosial belastning. Betatide er et nytt antimikrobielt peptid som binder til ... -
Identification of Regulatory Genes and Metabolic Processes Important for Alginate Biosynthesis in Azotobacter vinelandii by Screening of a Transposon Insertion Mutant Library
(Journal article; Peer reviewed, 2020)Azotobacter vinelandii produces the biopolymer alginate, which has a wide range of industrial and pharmaceutical applications. A random transposon insertion mutant library was constructed from A. vinelandii ATCC12518Tc in ... -
Identification of Sources for Illegal Oil Spills by Using GC-MS (Gas Chromatography and Mass-Spectrometry) Databases and Multivariate Statistics
(Master thesis, 2011)Preparing a defensible oil spill fingerprinting is always challenging. Presently available well established method for this purpose is a univariate method by comparison of diagnostic ratio using repeatability limit as ... -
Identification of tolerance levels on the coldwater coral Desmophyllum pertusum (Lophelia pertusa) from realistic exposure conditions to suspended bentonite, barite and drill cutting particles
(Peer reviewed; Journal article, 2022)Cold-water coral (CWC) reefs are numerous and widespread along the Norwegian continental shelf where oil and gas industry operate. Uncertainties exist regarding their impacts from operational discharges to drilling. Effect ... -
Identifikasjon av Nrf2-målgener i musecellelinje 66cl4 vha ChIP-sekvensering
(Bachelor thesis, 2021)Brystkreft er den mest prevalente kreftformen blant kvinner i Norge. I forskningen har transkripsjonsfaktorer og deres innvirkning på spredning av kreftceller blitt hyppigere undersøkt de siste årene. Hovedformålet med ... -
Identifikasjon av ukjente legemidler og misbruksstoffer ved spektersøk på GCMS ved bruk av deconvolution software
(Master thesis, 2009)Hensikt og problemstilling: Gasskromatografi-massespektrometri (GCMS) brukes ofte i laboratorier som utfører toksikologisk screening etter legemidler, giftstoffer og misbruksstoffer i biologiske prøver. Det kan imidlertid ... -
Identifikasjon og karakterisering av Photobacterium stammer isolert fra rødspette (Pleuronectes platessa)
(Master thesis, 2022)Photobacterium spp. er påvist som dominerende forringelsesbakterie i rødspette uavhengig av sesong og pakkebetingelser. For å tilrettelegge produktutvikling av lett prosesserte, enkle og forbrukervennlige produkter av ... -
Identifisering av, og biofilmegenskaper blant, Pseudomonas spp. fra et lakseslakteri – påvirkning på vekst og overlevelse av Listeria innocua.
(Master thesis, 2020)Norsk oppdrettsnæring er verdensledende og utgjør 53 % av verdens totalproduksjon. I 2019 eksporterte Norge 1,1 million tonn laks for 72,5 milliarder kroner. En del av moderne og sunn livstil har blitt å konsumere mer ... -
Identifying active constraintregions for optimal operationof process plants: With application to LNG and distillation processes
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:284, Doctoral thesis, 2011)Optimal operation and control of chemical processes depends on external conditions or disturbances. In order to achieve optimal or near-optimal control,one wants to control the active constraints, and the active constraints ... -
Identifying Barriers in Extracellular Matrix for Ultrasound-Mediated Delivery of Nanoparticles in 4T1, KPC and CT26 Tumor Models
(Master thesis, 2023)En av utfordringene ved dagens kreftbehandlinger er at kun en liten del av medisinene akkumuleres i svulsten. Man tror noe av grunnen til dette skyldes at den ekstracellulære matriksen (ECM) i svulstvevet er ekstra tettpakket. ... -
Identifying Conservative Criteria for (environmental) Assessments of Vulnerability;: Seabirds and Offshore Wind Farms as a Case Study
(Master thesis, 2013)The approach is based on four criterias; 1) elasticity of adult and juvenile survival on population growth rate, 2) redlist status and 3) local abundances and 4) flight properties. I also investigated whether the different ... -
