Nitrifier abundance and diversity peak at deep redox transition zones
(Peer reviewed; Journal article, 2019-06-14)More than half of the global ocean floor is draped by nutrient-starved sediments characterized by deep oxygen penetration and a prevalence of oxidized nitrogen. Despite low energy availability, this habitat hosts a vast ... -
Nitrite accumulation and anammox bacterial niche partitioning in Arctic Mid-Ocean Ridge sediments
(Journal article; Peer reviewed, 2023)By consuming ammonium and nitrite, anammox bacteria form an important functional guild in nitrogen cycling in many environments, including marine sediments. However, their distribution and impact on the important substrate ... -
Nitrogen dynamics in Turbic Cryosols from Siberia and Greenland
(Peer reviewed; Journal article, 2013-12)Turbic Cryosols (permafrost soils characterized by cryoturbation, i.e., by mixing of soil layers due to freezing and thawing) are widespread across the Arctic, and contain large amounts of poorly decomposed organic material ... -
Nitrous Oxide Adsorption and Separation Using CPO-27 Metal-Organic Frameworks
(Master thesis, 2020-08-29)Nitrous oxide N2O is a potent greenhouse gas with a high global warming potential approximately 300 times that of carbon dioxide on a 100-year timescale. In addition, it is the leading ozone-depleting substance emitted in ... -
Nivådeling i matematikk på ungdomsskolen - en kvalitativ undersøkelse
(Master thesis, 2012-05-30)I Kunnskapløftet, K06, legges det stor vekt på tilpasset opplæring til hver enkelt elev. Flere ungdomsskoler har innført nivådeling i matematikk som et tiltak for å imøtekomme dette kravet. I Norge står enhetsskoletanken ... -
NMR Characterization of LtL-oil
(Master thesis, 2020-07-02) -
NMR measurements of wettability alternation in Berea Sandstone
(Master thesis, 2011-11-28)When a new oil reservoir is discovered and a production strategy is chosen the knowledge about wettability characteristics for the field is of outermost importance. Wettability is a key factor for fluid distribution and ... -
An NMR study of α-lactalbumin pka-determinations and structural calculations
(Master thesis, 2004) -
An NMR Study on Hydration and Molecular Interaction of Phytantriol‐Based Liquid Crystals
(Journal article; Peer reviewed, 2022-10-27)Phytantriol-based lyotropic liquid crystals (LLCs) have emerged as a new nanodrug delivery system. However, the understanding of phytantriol-based LLCs is lacking. In this study, we use NMR technology to characterize LLC ... -
No environmental effect on vaccine-induced reduced growth in Atlantic salmon Salmo salar smolts
(Journal article; Peer reviewed, 2020)Oil-adjuvanted vaccines reduce long-term growth in farmed Atlantic salmon Salmo salar, possibly via an increase in metabolic rate due to the energetic demands of the immune system. We tested this hypothesis by comparing ... -
No influence of oxygen levels on pathogenesis and virus shedding in Salmonid alphavirus (SAV)-challenged Atlantic salmon (Salmo salar L.)
(Peer reviewed; Journal article, 2010-08-21)Background For more than three decades, diseases caused by salmonid alphaviruses (SAV) have become a major problem of increasing economic importance in the European fish-farming industry. However, experimental infection ... -
No room for dessert: A mechanistic model of prey selection in gut-limited predatory fish
(Peer reviewed; Journal article, 2020)Predatory fish structure communities through prey pursuit and consumption and, in many marine systems, the gadoids are particularly important. These predators have flexible feeding behaviours and often feed on large prey ... -
Nodavirus in farmed Atlantic cod Gadus morhua in Norway
(Peer reviewed; Journal article, 2007-09-14)Viral encephalopathy and retinopathy (VER) was diagnosed in 5 to 24 g sized farmed Atlantic cod Gadus morhua kept in sea cages at Parisvatn, Hordaland county, on the west coast of Norway. Moderate mortality (10 to 15%) was ... -
Node Multiway Cut and Subset Feedback Vertex Set on Graphs of Bounded Mim-Width
(Journal article; Peer reviewed, 2022)The two weighted graph problems Node Multiway Cut (NMC) and Subset Feedback Vertex Set (SFVS) both ask for a vertex set of minimum total weight, that for NMC disconnects a given set of terminals, and for SFVS intersects ... -

Noise and Cluster Size Studies of ALPIDE-CMOS Pixel Sensor for pCT
(Master thesis, 2018-07-04)The use of proton beam has been introduced in medical physics for therapeutic purposes in cancer treatment and it has been proven much more efficient than conventional X-ray. Treatment planning in proton therapy is usually ... -
Non-commutative Harmonic Analysis: Generalization of Phase Correlation to the Euclidean Motion Group
(Master thesis, 2010-06-10)This thesis is about noncommutative harmonic analysis, and generalization of phase correlation to the euclidean motion group and application in image processing. -
Non-conserved C-terminal regions in the histone recognition module CW, determines specificity, stability and affinity towards monomethylated histone tails
(Master thesis, 2014-11-20)Histone modifications have an important role in epigenetic gene regulation and contribute to the cellular memory system. It has been well documented that certain patterns of histone modifications are associated with different ... -
Non-Constructivity in Kan Simplicial Sets
(Journal article; Peer reviewed, 2015)We give an analysis of the non-constructivity of the following basic result: if X and Y are simplicial sets and Y has the Kan extension property, then Y X also has the Kan extension property. By means of Kripke countermodels ...
