Rensing og karakterisering av mannuronan C-5-epimeraser produsert rekombinant i Hansenula polymorpha og mutante epimeraser produsert rekombinant i Escherichia coli
(Master thesis, 2012)Alginat er et polysakkarid som kommersielt utvinnes fra algekilder. Anvendelsesområder for alginat er blant annet mat, farmasi og biomedisin. Strukturen til alginat er avhengig av kilden den er ekstrahert fra, og komposisjonen ... -
Renskefiskens adferd i naturlig miljø og merd.
(Bachelor thesis, 2016)Denne oppgaven gjør rede for rensefiskens atferd i naturlig miljø og i merd, sett i velferdssammenheng. Oppgaven omhandler artene rognkjeks og berggylt, der rognkjeks blir mest vektlagt. Hensikten er å se om miljøet i merd ... -
RENSVEL OWI FACT SHEET SERIES: An introduction to Operational and Laboratory-based Welfare Indicators for lumpfish (Cyclopterus lumpus L.)
(Research report, 2019)Fish welfare, defined by Stien et al., (2013) as the “quality of life as perceived by the animals themselves” requires various tools to assess and evaluate it (see e.g. Noble et al., 2018). These tools are termed Welfare ... -
Repeatability and Flexibility in the Migration Strategies of an Arctic Seabird
(Master thesis, 2016)The strategy of migration has evolved independently in many animal groups, but it is most widely and well developed in birds. Migrating species are expected to be severely affected by human induces climate change, and the ... -
Repeatability in isotopic signatures is linked to consistent individual migration strategies and individual specialization in a long-distance migratory seabird
(Master thesis, 2018)Animal populations can consist of specialized individuals with different foraging strategies. There could be several advantages for specialized individuals, such as higher foraging efficiency, breeding success and survival. ... -
Repeatable individual variation in migration timing in two anadromous salmonids and ecological consequences
(Journal article; Peer reviewed, 2020)Consistent individual differences in behavior have been demonstrated for many animals, but there are few studies of consequences of such repeated behavior in the wild. We tested consistency in migration timing to and from ... -
Repeatable Territorial Aggression in a Neotropical Poison Frog
(Peer reviewed; Journal article, 2022)Intra-specific aggressive interactions play a prominent role in the life of many animals. While studies have found evidence for repeatability in boldness, activity, and exploration in amphibians, we know relatively little ... -
Replacement of Ensemble Averaging by the Use of a Broadband Source in Scattering of Light from a One-Dimensional Randomly Rough Interface between Two Dielectric Media
(Journal article; Peer reviewed, 2018)By the use of phase perturbation theory we show that if a single realization of a one-dimensional randomly rough interface between two dielectric media is illuminated at normal incidence from either medium by a broadband ... -
Replacement of refined sugar by natural sweeteners: focus on potential health benefits
(Peer reviewed; Journal article, 2022)Refined sugar is a processed product containing 99% sucrose, which is obtained from sugarcane (70%) or sugar beet (30%). In modern societies, sugar continues to play a significant role in the diet, recognised not only for ... -

Reporter genes for relative quantification of promoter strength and c-di-GMP in Pseudomonas fluorescens.
(Master thesis, 2021)Alginat er en industrielt viktig polymer som består av de to monomerene mannuronsyre og guluronsyre. Denne polymeren kan brukes til å transportere legemidler inn i kroppen, sårheling og muligens i vevsregenerering. Alginat ... -
Representation of pheromones, interspecific signals, and plant odors in higher olfactory centers; mapping physiologically identified antennal-lobe projection neurons in the male heliothine moth
(Journal article; Peer reviewed, 2014)The arrangement of anatomically separated systems for information about general and pheromone odorants is well documented at the initial levels of the olfactory pathway both in vertebrates and insects. In the primary ... -
Reproducibility of fluorescent expression from engineered biological constructs in E. coli.
(Peer reviewed; Journal article, 2016)We present results of the first large-scale interlaboratory study carried out in synthetic biology, as part of the 2014 and 2015 International Genetically Engineered Machine (iGEM) competitions. Participants at 88 institutions ... -
Reproductive and migratory challenges inflicted on migrant brown trout ( Salmo trutta L. ) in a heavily modified river
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:136, Doctoral thesis, 2012) -
Reproductive strategies in Scandinavian brown bears
(Doctoral thesis, 2003)Denne avhandlingen tar for seg noen sentrale aspekt ved reproduktive strategier hos brunbjørn. Første del tar for seg strategier for foreldreomsorg og hvordan disse påvirker størrelsen og overlevelsen på avkommet. Deretter ... -
Requirements Elicitation On Integrating Clinical Guidelines To Electronic Patient Record: An Empirical Study
(Master thesis, 2012)There is little research on the requirements elicitation of integrating of clinical guidelines and electronic patient record while in this master project I managed to use different methods to collect and elicit requirements ... -

Research on sablefish (Anoplopoma fimbria) suggests that limited capacity to increase heart function leaves hypoxic fish susceptible to heat waves
(Peer reviewed; Journal article, 2021)Studies of heart function and metabolism have been used to predict the impact of global warming on fish survival and distribution, and their susceptibility to acute and chronic temperature increases. Yet, despite the fact ... -
