Chromatin and epigenetic features of long-range gene regulation
(Peer reviewed; Journal article, 2013-06-13)The precise regulation of gene transcription during metazoan development is controlled by a complex system of interactions between transcription factors, histone modifications and modifying enzymes and chromatin conformation. ... -
Chromatographic Fingerprinting and Quality Control of Herbal Medicines: Comparison of two officinal Chinese pharmacopoeia species of Dendrobii based on High-Performance Liquid Chromatography and Chemometric analysis
(Master thesis, 2013-08-29)The fingerprinting quantitative analysis combining similarity evaluation, Principal Component Analysis (PCA) and Partial Least Squares Discriminant Analysis (PLS-DA) is a valid method for classification of herbal medicine ... -
Chromatographic Fingerprinting of Chinese Grape Berries
(Master thesis, 2014-04-14)Chromatographic fingerprints from three varieties of grapes produced in China (Giant Rose, Red Globe and Summer Black), were obtained by gas chromatography coupled with mass spectrometry. These grapes were subjected to ... -
Chromosome aberrations in pressureinduced triploid Atlantic salmon
(Journal article; Peer reviewed, 2020)Background Triploid organisms have three sets of chromosomes. In Atlantic salmon, hydrostatic pressure treatment of newly fertilized eggs has been extensively used to produce triploids which are functionally sterile due ... -
A chromosome-level assembly of the Atlantic herring genome-detection of a supergene and other signals of selection
(Peer reviewed; Journal article, 2019)The Atlantic herring is a model species for exploring the genetic basis for ecological adaptation, due to its huge population size and extremely low genetic differentiation at selectively neutral loci. However, such studies ... -
Chronology of Early to Mid-Pleistocene sediments in the northern North Sea: New evidence from amino acid and strontium isotope analyses
(Journal article; Peer reviewed, 2022)Sediments deposited during glacial-interglacial cycles through the Early to Mid-Pleistocene in the North Sea are chronologically poorly constrained. To contribute to the chronology of these units, amino acid racemization ... -
The chronology of reindeer hunting on Norway's highest ice patches
(Peer reviewed; Journal article, 2018-01-24)The melting of perennial ice patches globally is uncovering a fragile record of alpine activity, especially hunting and the use of mountain passes. When rescued by systematic fieldwork (glacial archaeology), this evidence ... -
Circulation along the northern slope of the Greenland-Scotland Ridge
(Doctoral thesis, 2020-12-11)The Greenland-Scotland Ridge separates the subpolar North Atlantic from the Nordic Seas and constrains the flow of the upper and lower branches of the northern extremity of the Atlantic Meridional Overturning Circulation ... -
Circulation and exchange of water masses on the Faroe Shelf and the impact on the Shelf ecosystem
(Doctoral thesis, 2009-02-11)The findings in this work can be listed as follows: FSW: Based on CTD data, the FSW is found to be relatively vertically homogeneous through-out the year inside the 100 m depth contour. Temperature measurements at coastal ... -
Circulation and Ocean Driven Glacial Melting in a Greenland Fjord
(Master thesis, 2017-11-20)The Nioghalvfjerdsbræ (79NG) is a floating ice tongue on Northeast Greenland draining a large part of the Greenland Ice Sheet. New hydrographic observations show that Atlantic Water (AW, T > 0 °C, S > 34.3 psu) recirculates ... -
Circulation and transformation of Atlantic and Arctic water masses in climate models
(Doctoral thesis, 2011-12-09)Ocean heat transport and associated heat loss to the atmosphere contributes significantly to the anomalously mild climate of northwestern Europe and its variability. In this thesis, the circulation and transformation of ... -
Circulation and water masses beneath the northern Ronne Ice Shelf, Antarctica
(Journal article, 2004-12-14)We present oceanographic data from beneath the northern Ronne Ice Shelf. The data were collected during the austral summer of 2002–2003 from four sites located near the ice front in the Ronne Depression. They consist of ... -
Circulation features in the northern North Atlantic Ocean inferred from simulated radioactive tracers
(Doctoral thesis, 2008-03-12) -
The circulation of the Norwegian Sea- An investigation from space and ocean
(Doctoral thesis, 2014-01-10)The Norwegian Sea circulation plays a key role in maintaining the mild climate of the northwestern Europe via the transport of warm Atlantic Water pole-ward. The first paper addresses the advective currents connecting the ... -
Circum-Arctic distribution of chemical anti-herbivore compounds suggests biome-wide trade-off in defence strategies in Arctic shrubs
(Journal article; Peer reviewed, 2022)Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top–down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, ... -
Citizen Seismology in the Arctic
(Journal article; Peer reviewed, 2020)Landslides, earthquakes and other natural disasters are expected to increase in the Arctic, yet our ability to make informed decisions about safety is tightly limited by lack of data. As part of the Integrated Arctic ... -
The cladorhizid fauna (Porifera, Poecilosclerida) of the Caribbean and adjacent waters
(Peer reviewed; Journal article, 2016-10-19)The carnivorous sponge family Cladorhizidae has been subject to several recent studies, yet the cladorhizid fauna of the Caribbean and adjacent areas remain comparatively poorly known. In this article we provide a description ... -
Cladorhizid sponges from hydrothermal vents and cold seeps in the NE Atlantic Ocean
(Master thesis, 2009-09-30)Sponges are known to frequently contain a great number of symbiotic organisms. Symbiosis is also a characteristic trait of vent and seep animals worldwide. Sponges in the deep sea family Cladorhizidae, otherwise also known ... -
Class I Phosphoinositide 3-Kinase PIK3CA/p110α and PIK3CB/p110β Isoforms in Endometrial Cancer
(Peer reviewed; Journal article, 2018-12-07)The phosphoinositide 3-kinase (PI3K) signalling pathway is highly dysregulated in cancer, leading to elevated PI3K signalling and altered cellular processes that contribute to tumour development. The pathway is normally ... -
Classes of Intersection Digraphs with Good Algorithmic Properties
(Journal article; Peer reviewed, 2022)While intersection graphs play a central role in the algorithmic analysis of hard problems on undirected graphs, the role of intersection digraphs in algorithms is much less understood. We present several contributions ...
