Transfection optimization and gene editing method establishment for fish cells
(Master thesis, 2021)Aquaculture is one of the fastest-growing industries around the world, and salmonoid aquaculture is a very big industry for Norway. Ensuring fish health and welfare is essential for aquaculture, also to avoid economic loss. ... -
Transient gene editing in Potato (Solanum tuberosum L.) with CRISPR/Cas9 to knock-out F3H
(Master thesis, 2020)With the continuous desire for crops with superior qualities, the CRISPR/Cas9 gene editing system seems to be a promising, cost-effective, efficient and a much faster method of developing new superior varieties compared ... -
Transposable Elements as a Source of Novel Gene Regulation in Atlantic Salmon (Salmo salar)
(Master thesis, 2021)It has become evident over the last decade that transposable elements play an extensive role in gene regulatory evolution. Their ability to transpose close to genes, while also acting as cis-regulatory elements, permits ... -
Trends in runs of homozygosity and inbreeding in Norwegian Red Cattle before and after implementation of genomic selection
(Master thesis, 2020)Background: Despite commercial breeding being part of the genomic era, routine use of genotype data to govern inbreeding is still scarce. Recent studies have found acceleration of inbreeding rates after implementation of ... -
Two different oils in feeds for poultry : effects on feed digestion
(Master thesis, 2014-02-10)The objective of present study was to investigate the digestibility of fat in the different segments of the small intestine in broiler chickens fed with two different feed containing either 4% soybean oil or 2% rapeseed ... -
Ulikhet i helse blant minoriteter. Med fokus på salutogenese for helseutjevning
(Master thesis, 2010-12-13)Current evidence shows substantial inequalities amongst different groups of people in Norway. Accordingly, the authorities have designated a national plan with a clear objective of reducing inequalities in health in the ... -
Ultraviolet radiation as a tool to control Tetranychus urticae in greenhouse production
(Master thesis, 2017)Tetranychus urticae Koch has an ubiquitous distribution, is remarkably polyphagous and is known to be the most acaricide resistant arthropod. This thesis examines how short wavelengths of ultraviolet radiation (UV) can be ... -
En undersøkelse av en datastyrt kraftfôrstasjon til sau
(Master thesis, 2013-03-26)Formålet med denne oppgaven var å studere hvordan en datastyrt kraftfôrstasjon for sau virker inn på antall belønnede og ubelønnede besøk, fortrenginger og kødannelse i fire forskjellige besetninger med vinterfôret sau, ... -
Undersøkelse av mulige biotiske årsaker til forsinket spiring i potet gjennom DNA-metastrekkoding og morfologisk nematodeanalyse : en casestudie
(Master thesis, 2022)Forsinket spiring hos potetplanter, og redusert avling og kvalitet ble observert på betydelige arealer i flere potetåkere på Engeløya i Nordland i 2018 og 2019. Ingen åpenbar årsak ble funnet. Det ble tatt jordprøver i ... -
Unge søyers preferanser for golvtyper ved lave temperaturer
(Master thesis, 2016-08-18)Formålet med masteroppgaven var å undersøke unge søyers preferanser for ulike golvtyper ved hjelp av valgforsøk ved lave temperaturer. I tillegg ble golvtypenes varmetekniske egenskaper undersøkt. Valgforsøket ble gjennomført ... -
Unicellular algae from the genus chlorella grown under various conditions : potential for use as feed
(Master thesis, 2016-08-18)Diverse morphological and physiological characteristics of microalgae are enabling their use in the production of protein, vitamins, antioxidants, drugs, immunostimulants, biofuels and food supplements. These physiological ... -
Unraveling the genetic mysteries of the Norwegian Fjord-horse : identifying harmful haplotypes for improved breeding strategies
(Master thesis, 2023)Fertiliteten til avlsdyrene er særdeles kritisk i små populasjoner med høy innavl. Fjordhest-populasjonen i Norge består av få stamfedre, og er blitt registrert til å ha en lavere føllings-rate enn flere andre hesteraser. ... -
Upgrading plant ingredients in feed for salmonids by thermo-mechanical treatment and acid salts
(PhD Thesis;2011:52, Doctoral thesis, 2011)Inclusion of plant ingredients in diets for salmonids is restricted due to low energy contents, unbalanced amino acid (AA) composition and presence of antinutritional factors (ANF). The objective of this thesis was to ... -
Urban gardeners in Oslo : an explorative study of their motivations and the perceived effects of gardening on quality of life
(Master thesis, 2019)Urban agriculture has been associated with social, emotional, health and mental health benefits. However, literature describing the relationship between garden participation and effects on quality of life has not been fully ... -
