Histochemical characterization of AGD lesions in ballan wrasse (Labrus bergylta)
(Master thesis, 2017-07-07)With the increasing problem of sea lice (Lepeoptheirus salmonis) in production of Atlantic salmon (Salmo salar), the use of biological and non-drug treatments, such as cleaner fish, like ballan wrasse (Labrus bergylta) and ... -
Histological investigation of gill health responses to recirculating aquaculture system (RAS) water quality in apparently healthy Atlantic salmon (Salmo salar)
(Master thesis, 2020-08-04)Recirculating aquaculture system (RAS) technology has become more widespread in Atlantic salmon farming, and the need for knowledge about operating such a system has been highlighted in recent years. Gill pathology has ... -
Histone complement of a rapidly evolving chordate Oikopleura dioica: Developmental and sex-specific deployment of novel and universal histone variants and their posttranslational modifications
(Doctoral thesis, 2010-10-22)The packaging of DNA into nucleosomes is a fundamentally conserved property of the eukaryotic nucleus which is evident in the conservation of histone sequences. Nevertheless, it is now clear that histone sequence variants ... -
Histone variant innovation in a rapidly evolving chordate lineage
(Peer reviewed; Journal article, 2011-07-15)Background: Histone variants alter the composition of nucleosomes and play crucial roles in transcription, chromosome segregation, DNA repair, and sperm compaction. Modification of metazoan histone variant lineages occurs ... -
Historical and future runoff changes in the Yangtze River Basin from CMIP6 models constrained by a weighting strategy
(Journal article; Peer reviewed, 2022)Based on the ERA5-Land datasets from 1981–2020, a decadal oscillation has been found in the variation of summer runoff in the middle and lower reaches of the Yangtze River Basin (MLYRB). The oscillation suggests that the ... -
Historical changes in macroalgal communities in Hardangerfjord (Norway)
(Peer reviewed; Journal article, 2014)Hardangerfjord is the second largest fjord in Norway and is situated on the southwest coast. During the last century the fjord has been influenced by a variety of anthropogenous activities such as industry, hydro-electrical ... -
History Matching with Reduced Parameterization and Fast Streamline-based Sensitivities
(Master thesis, 2012-09-27)The main goal of history matching is to construct updated models capable of predicting the future performance of the reservoir more accurately. History matching method requires a solution of inverse problem to minimize the ... -
Hit Dexter 2.0: Machine-Learning Models for the Prediction of Frequent Hitters
(Journal article; Peer reviewed, 2019)Assay interference caused by small molecules continues to pose a significant challenge for early drug discovery. A number of rule-based and similarity-based approaches have been derived that allow the flagging of potentially ... -
Hitting Topological Minor Models in Planar Graphs is Fixed Parameter Tractable
(Journal article; Peer reviewed, 2020)For a finite collection of graphs F, the F-TM-Deletion problem has as input an n-vertex graph G and an integer k and asks whether there exists a set S ⊆ V(G) with |S| ≤ k such that G \ S does not contain any of the graphs ... -
HIV-1 Rev oligomerization is not obligatory in the presence of an extra basic domain
(Peer reviewed; Journal article, 2005-06-10)Background: The HIV-1 Rev regulatory protein binds as an oligomeric complex to viral RNA mediating nuclear export of incompletely spliced and non-spliced viral mRNAs encoding the viral structural proteins. However, the ... -
A Holarctic Biogeographical Analysis of the Collembola (Arthropoda, Hexapoda) Unravels Recent Post-Glacial Colonization Patterns
(Peer reviewed; Journal article, 2011-06-29)We aimed to describe the main Arctic biogeographical patterns of the Collembola, and analyze historical factors and current climatic regimes determining Arctic collembolan species distribution. Furthermore, we aimed to ... -
Holocen rekonstruksjon av Kongsbreen, Svalbard
(Master thesis, 2019-06-26)Dette masterprosjektet har ved bruk av innsjøsedimenter og kvartærgeologisk kartlegging rekonstruert posisjonen til brefronten til Kongsbreen gjennom holocen. Studien er basert på en sedimentkjerne fra Sarsvatnet, nordvest ... -
Holocene avsetningsprosesser i Fjærlandsfjorden basert på marine data
(Master thesis, 2019-06-08)Sedimentbassenger i vestnorske fjorder utgjør et viktig arkiv for å rekonstruere avsetningsmiljø og pre-historisk skredaktivitet samtidig som det gir et indirekte innblikk i hvordan klima har endret seg. I dette studiet ... -
Holocene changes in atmospheric circulation recorded in the oxygen-isotope stratigraphy of lacustrine carbonates from northern Sweden
(Peer reviewed; Journal article, 2002)The oxygen-isotope composition of local precipitation (d18OP) is reconstructed from carbonate lake-sediment components in a sediment core covering the last 10000 calendar years from Lake Tibetanus, a small, hydrologically ... -
Holocene climatic change reconstructed from diatoms, chironomids, pollen and near-infrared spectroscopy at an alpine lake (Sjuodjijaure) in northern Sweden
(Peer reviewed; Journal article, 2001)The results of a multiproxy study reconstructing the climate history of the last 9300 years in northern Sweden are presented. It is based on diatom, chironomid and pollen analyses, as well as near-infrared spec troscopy ... -
