Long-term microbial community structures and dynamics in a commercial RAS during seven production batches of Atlantic salmon fry (Salmo salar)
(Peer reviewed; Journal article, 2023)The microbiota of recirculating aquaculture systems (RAS) is of major importance for optimal fish health. However, the microbial communities in commercial RAS are highly complex and more knowledge is needed to potentially ... -
Long-term performance of highly selective carbon hollow fiber membranes for biogas upgrading in the presence of H<inf>2</inf>S and water vapor
(Peer reviewed; Journal article, 2022)Biogas is an increasingly attractive renewable resource that needs to be upgraded to meet either the natural gas pipeline quality or the biomethane requirement. The use of carbon membranes is a promising alternative to ... -
Long-term prediction of fish growth under varying ambient temperature using a multiscale dynamic model
(Journal article; Peer reviewed, 2009)Background: Feed composition has a large impact on the growth of animals, particularly marine fish. We have developed a quantitative dynamic model that can predict the growth and body composition of marine fish for a ... -
Long-term stability of screen-printed pseudo-reference electrodes for electrochemical biosensors
(Journal article; Peer reviewed, 2018)Pseudo reference electrodes forms an essential part of electrochemical transducers, where they are used to maintain a reference potential for the system. Yet, little is known about their long-term stability, and any drift ... -
Long-term trends in elephant mortality and their causes in Kenya
(Peer reviewed; Journal article, 2022)High mortality poses a serious threat to sustainable conservation of the African elephant (Loxodonta africana). Using detected carcass data collected by the Kenya Wildlife Service (KWS) during 1992-2017, we analyze temporal ... -
Longitudinal and secular trends in total cholesterol levels and impact of lipid-lowering drug use among Norwegian women and men born in 1905–1977 in the population-based Tromsø Study 1979–2016
(Journal article; Peer reviewed, 2017)Objectives Elevated blood cholesterol is a modifiable risk factor for cardiovascular disease. Cholesterol level surveillance is necessary to study population disease burden, consider priorities for prevention and intervention ... -
Longitudinal telomere dynamics within natural lifespans of a wild bird
(Peer reviewed; Journal article, 2023)Telomeres, the nucleotide sequences that protect the ends of eukaryotic chromosomes, shorten with each cell division and telomere loss may be influenced by environmental factors. Telomere length (TL) decreases with age in ... -
Looking for alien invertebrates in Norwegian ports, extensive sampling, and precise identification
(Master thesis, 2020)Fremmedarter er sammen med klimaendringer, tap av habitat, overhøsting og forurensning de mest alvorlige truslene globalt mot biologisk mangfold. I det marine miljø spres arter blant annet gjennom internasjonal skipstrafikk ... -
Looking for the Big Picture:Genome-Based Approaches to Improve Alginate Production in Azotobacter vinelandii
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:18, Doctoral thesis, 2014)Alginates are commercially important polysaccharides with a wide range of industrial and technological applications. Polymer chain length and monomer distribution greatly affect the material properties, which makes different ... -

Losing the 'arms race': Multiresistant salmon lice are dispersed throughout the North Atlantic Ocean
(Journal article; Peer reviewed, 2021)Nothing lasts forever, including the effect of chemicals aimed to control pests in food production. As old pesticides have been compromised by emerging resistance, new ones have been introduced and turned the odds back in ... -
Loss Measurements in Silicon Core Optical Waveguides
(Master thesis, 2013)Silicon core fibers have, because of their non-linear optical properties and transmission in the IR, recently been the focus of several different research groups. At NTNU, a new method for production of silicon fibers has ... -
Loss of ALBINO3b insertase results in truncated light-harvesting antenna in diatoms
(Journal article; Peer reviewed, 2019)The family of chloroplast ALBINO3 (ALB3) proteins function in the insertion and assembly of thylakoid membrane protein complexes. Loss of ALB3b in the marine diatom Phaeodactylum tricornutum leads to a striking change of ... -
Loss of CpFTSY Reduces Photosynthetic Performance and Affects Insertion of PsaC of PSI in Diatoms
(Peer reviewed; Journal article, 2023)The chloroplast signal recognition particle (CpSRP) receptor (CpFTSY) is a component of the CpSRP pathway that post-translationally targets light-harvesting complex proteins (LHCPs) to the thylakoid membranes in plants and ... -
Loss of NRF-2 and PGC-1α genes leads to retinal pigment epithelium damage resembling dry age-related macular degeneration
(Journal article; Peer reviewed, 2019)Age-related macular degeneration (AMD) is a multi-factorial disease that is the leading cause of irreversible and severe vision loss in the developed countries. It has been suggested that the pathogenesis of dry AMD involves ... -
Loss of the arabidopsis protein kinases ANPs affects root cell wall composition, and triggers the cell wall damage syndrome
(Journal article; Peer reviewed, 2018)The Arabidopsis NPK1-related Protein kinases ANP1, ANP2 and ANP3 belong to the MAP kinase kinase kinase (MAPKKK) superfamily and were previously described to be crucial for cytokinesis, elicitor-induced immunity and ... -
