A dead giveaway: Foraging vultures and other avian scavengers respond to auditory cues
(Peer reviewed; Journal article, 2020)Carrion represents an unpredictable and widely distributed primary food source for vultures and other avian scavengers. Avian scavengers in African savanna ecosystems are reported to rely exclusively on visual stimuli to ... -
Dead wood profile of a semi-natural boreal forest – implications for sampling
(Journal article; Peer reviewed, 2019)Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead ... -
Dealing with different conceptions of pollution in the Gene Regulation Knowledge Commons
(Peer reviewed; Journal article, 2022)Current research of gene regulatory mechanisms is increasingly dependent on the availability of high-quality information from manually curated databases. Biocurators undertake the task of extracting knowledge claims from ... -
Deammonifisering av Rejekt Forbehandlet med Termisk Hydrolyse
(Master thesis, 2019)Cambi sin termiske hydrolyse prosess(THP) er en kjent og effektiv forbehandlingsprosess for slam før den stabiliseres i en råtnetank. Vannstrømmen som resulterer etter at det fordøyde slammet er avvannet, er rik på ammonium ... -
Death signals during plant cell death. Macroscopic study of cell death induced by low pH and eATP.
(Master thesis, 2023)For tiden er forskning på celledød et utviklende og svært interessant tema. Celledød som dødsprosessen i mikroskala er en viktig kontrollmekanisme i alle levende organismer. Spesielt programmert cellulært "selvmord", som ... -
Deciphering biodiversity: On the taxonomy of Northern European Darwin wasps (Hymenoptera: Ichneumonidae)
(Doctoral theses at NTNU;2022:12, Doctoral thesis, 2022)Summary of thesis: Ichneumonid or Darwin wasps is one of, possibly the largest hymenopteran family on earth and constitute a large part of what we commonly refer to as biodiversity. Despite their often large and colorful ... -
Deciphering the composition and transformation of dissolved organic matter in recirculating aquaculture systems by high-resolution mass spectrometry
(Doctoral theses at NTNU;2022:237, Doctoral thesis, 2022)The continuous increase in the human population is prompting the need for aquaculture systems able to sustain the global demand for fish without affecting the environment. Recirculating aquaculture systems (RAS) are a new ... -
Deciphering the Composition of Fulvic Acids from Recirculating Aquaculture Systems by Quadrupole Time-of-Flight Mass Spectrometry
(Peer reviewed; Journal article, 2022)The constant reuse of waters in recirculating aquaculture systems (RAS) together with the continuous addition of organic matter from fish degradation components, faeces and non-consumed feed promote the accumulation of ... -
Deciphering the Electronic Transitions of Thiophene-Based Donor-Acceptor-Donor Pentameric Ligands Utilized for Multimodal Fluorescence Microscopy of Protein Aggregates.
(Journal article; Peer reviewed, 2020)Anionic pentameric thiophene acetates can be used for fluorescence detection and diagnosis of protein amyloid aggregates. Replacing the central thiophene unit by benzothiadiazole (BTD) or quinoxaline (QX) leads to large ... -
Decline of a grey seal (Halichoerus grypus) population in Norway: can per- and polyfluoroalkyl substances be blamed ?
(Master thesis, 2023)Bestanden av gråsel (Halichoerus grypus) i Froan Archipelago har gått drastisk ned siden 2001, og det blir en presserende utfordring å forstå de underliggende årsakene til denne nedgangen. Spesiell oppmerksomhet har blitt ... -
Decoding atomic-level structures of the interface between Pt sub-nanocrystals and nanostructured carbon
(Journal article; Peer reviewed, 2018)Gaining an insight into the interface structure resulting from the interaction between metal nanoparticles and their supports, particularly under relevant reaction conditions, has been an important topic in heterogeneous ... -
Decoding of Algebraic Geometry Codes
(Master thesis, 2011)Codes derived from algebraic curves are called algebraic geometry (AG) codes. They provide a way to correct errors which occur during transmission of information. This paper will concentrate on the decoding of algebraic ... -
Decomposing demographic contributions to the effective population size with moose as a case study
(Peer reviewed; Journal article, 2020)Levels of random genetic drift are influenced by demographic factors, such as mating system, sex ratio and age structure. The effective population size (N e) is a useful measure for quantifying genetic drift. Evaluating ... -
