Polychaetes from Jan Mayen (Annelida, Polychaeta)
(Peer reviewed; Journal article, 2010)A thorough literature review has been undertaken to establish the first complete account of polychaetes recorded from the area around the volcanic island of Jan Mayen. The annotated checklist lists 121 species-level taxa, ... -
Polycrystalline Diamond Coating on Orthopedic Implants: Realization and Role of Surface Topology and Chemistry in Adsorption of Proteins and Cell Proliferation
(Journal article; Peer reviewed, 2022)Polycrystalline diamond has the potential to improve the osseointegration of orthopedic implants compared to conventional materials such as titanium. However, despite the excellent biocompatibility and superior mechanical ... -
Polycyclic aromatic hydrocarbons (PAHs) and their nitrated and oxygenated derivatives in the Arctic boundary layer: Seasonal trends and local anthropogenic influence
(Journal article; Peer reviewed, 2021)A total of 22 polycyclic aromatic hydrocarbons (PAHs), 29 oxy-PAHs, and 35 nitro-PAHs (polycyclic aromatic compounds, PACs) were measured in gaseous and particulate phases in the ambient air of Longyearbyen, the most ... -
Polycyclic aromatic hydrocarbons modulate the activity of Atlantic cod (Gadus morhua) vitamin D receptor paralogs in vitro
(Journal article; Peer reviewed, 2021)Vitamin D receptor (VDR) mediates the biological function of the steroid hormone calcitriol, which is the metabolically active version of vitamin D. Calcitriol is important for a wide array of physiological functions, ... -
Polycystisk ovariesyndrom: svangerskapsomsorg og tidlig livsstilssamtale
(Master thesis, 2015-11-14) -
Polygenic overlap and shared genetic loci between loneliness, severe mental disorders, and cardiovascular disease risk factors suggest shared molecular mechanisms
(Journal article; Peer reviewed, 2021)Clinical and epidemiological evidence suggest that loneliness is associated with severe mental disorders (SMDs) and increases the risk of cardiovascular disease (CVD). However, the mechanisms underlying the relationship ... -
Polygenic overlap between C-reactive protein, plasma lipids, and Alzheimer disease
(Peer reviewed; Journal article, 2015-06)Background—Epidemiological findings suggest a relationship between Alzheimer disease (AD), inflammation, and dyslipidemia, although the nature of this relationship is not well understood. We investigated whether this ... -
Polygenic overlap with body-mass index improves prediction of treatment-resistant schizophrenia
(Journal article; Peer reviewed, 2023)Treatment resistant schizophrenia (TRS) is characterized by repeated treatment failure with antipsychotics. A recent genome-wide association study (GWAS) of TRS showed a polygenic architecture, but no significant loci were ... -
Polygenic risk modeling for prediction of epithelial ovarian cancer risk
(Journal article; Peer reviewed, 2022)Polygenic risk scores (PRS) for epithelial ovarian cancer (EOC) have the potential to improve risk stratification. Joint estimation of Single Nucleotide Polymorphism (SNP) effects in models could improve predictive performance ... -
A polygenic risk score to help discriminate primary adrenal insufficiency of different etiologies
(Journal article; Peer reviewed, 2023)Background Autoimmune Addison's disease (AAD) is the most common cause of primary adrenal insufficiency (PAI). Despite its exceptionally high heritability, tools to estimate disease susceptibility in individual patients ... -
Polygenic scores for schizophrenia and general cognitive ability: associations with six cognitive domains, premorbid intelligence, and cognitive composite score in individuals with a psychotic disorder and in healthy controls
(Journal article; Peer reviewed, 2020-11)Cognitive impairments are considered core features in schizophrenia and other psychotic disorders. Cognitive impairments are, to a lesser degree, also documented in healthy first-degree relatives. Although recent studies ... -
Polygonal faults in the northern North Sea
(Master thesis, 2021-06-01)Polygonal faults have been studied in sedimentary basins at the Norwegian continental shelf and globally as non-tectonic normal faults. The polygonal faults have been recognized for a long time, but no one has described ... -
Polygonalforkastninger - karakteristikk og dannelsesmekanismer. En studie basert på tolking av seismiske data fra Norske-Barentshavsmarginen
(Master thesis, 2014-09-22)Polygonale forkastningssystemer (PFS) er bemerkelsesverdige strukturer som er identifisert i en rekke sedimentære bassenger over hele verden. Polygonalforkastninger er normalforkastninger med små sprang som hovedsakelig ... -
Polyhedra and algorithms for problems bridging notions of connectivity and independence
(Doctoral thesis, 2023-12-21)I denne avhandlinga interesserer vi oss for å finne delgrafer som svarer til utvalgte modeller for begrepene sammenheng og uavhengighet. I korthet betyr dette stabile (også kalt uavhengige) mengder med gitt kardinalitet, ... -
Polyhedral results and stronger Lagrangean bounds for stable spanning trees
(Journal article; Peer reviewed, 2023)Given a graph G=(V,E) and a set C of unordered pairs of edges regarded as being in conflict, a stable spanning tree in G is a set of edges T inducing a spanning tree in G, such that for each {ei,ej}∈C, at most one of the ... -
Polymastiidae (Demospongiae: Hadromerida) with ornamented exotyles: a review of morphological affinities and description of a new genus and three new species
(Peer reviewed; Journal article, 2016)All polymastiid sponges displaying ornamented exotyles are reviewed and their morphological affinities are reconsidered. The study embraces all known species of Proteleia, Sphaerotylus, Trachyteleia and Tylexocladus as ... -
Polymer Enhanced Foam in Unconsolidated Sand
(Master thesis, 2016-06-01)Foam is an EOR technique that significantly can improve the macroscopic sweep efficiency by lowering the gas mobility. Limited stability of conventional surfactants for foam generation is one of the reasons why foam is not ... -
Polymer flow in porous media: Relevance to Enhanced Oil Recovery
(Peer reviewed; Journal article, 2018-07-10)Polymer flooding is one of the most successful chemical EOR (enhanced oil recovery) methods, and is primarily implemented to accelerate oil production by sweep improvement. However, additional benefits have extended the ... -
