Polymer Injectivity: Investigation of Mechanical Degradation of Enhanced Oil Recovery Polymers Using In-Situ Rheology
(Peer reviewed; Journal article, 2018-12-24)Water soluble polymers have attracted increasing interest in enhanced oil recovery (EOR) processes, especially polymer flooding. Despite the fact that the flow of polymer in porous medium has been a research subject for ... -
The polymorphism L412F in TLR3 inhibits autophagy and is a marker of severe COVID-19 in males
(Journal article; Peer reviewed, 2021)The polymorphism L412F in TLR3 has been associated with several infectious diseases. However, the mechanism underlying this association is still unexplored. Here, we show that the L412F polymorphism in TLR3 is a marker of ... -
Polymorphisms in hormone metabolism and growth factor genes and mammographic density in Norwegian postmenopausal hormone therapy users and non-users
(Peer reviewed; Journal article, 2012-10-27)Introduction: Mammographic density (MD) is one of the strongest known breast cancer risk factors. Estrogen and progestin therapy (EPT) has been associated with increases in MD. Dense breast tissue is characterized by ... -
Polymorphisms in the TP53-MDM2-MDM4-axis in patients with rheumatoid arthritis
(Journal article; Peer reviewed, 2021)Background In addition to being a tumour suppressor, TP53 is a suppressor of inflammation, and dysfunction of this gene has been related to autoimmune diseases. Patients with autoimmunity, such as rheumatoid arthritis ... -
Polymorphisms of the XRCC1, XRCC3 and XPD genes and risk of colorectal adenoma and carcinoma, in a Norwegian cohort : a case control study
(Peer reviewed; Journal article, 2006-03-16)Background: Genetic polymorphisms in DNA repair genes may influence individual variation in DNA repair capacity, which may be associated with risk of developing cancer. For colorectal cancer the importance of mutations in ... -
A Polynomial Kernel for Line Graph Deletion
(Journal article; Peer reviewed, 2020)The line graph of a graph G is the graph L(G) whose vertex set is the edge set of G and there is an edge between e,f ∈ E(G) if e and f share an endpoint in G. A graph is called line graph if it is a line graph of some ... -
A Polynomial Kernel for Paw-Free Editing
(Journal article; Peer reviewed, 2020)For a fixed graph H, the H-free Edge Editing problem asks whether we can modify a given graph G by adding or deleting at most k edges such that the resulting graph does not contain H as an induced subgraph. The problem is ... -
A polynomial-time algorithm for LO based on generalized logarithmic barrier functions
(Peer reviewed; Journal article, 2008) -
A polynomial-time solvable case for the NP-hard problem Cutwidth
(Master thesis, 2014-06-02)The Cutwidth problem is a notoriously hard problem, and its complexity is open on several interesting graph classes. Motivated by this fact we investigate the problem on superfragile graphs, a graph class on which the ... -
Polynomials homologically supported on determinantal loci

Polypharmacy among anabolic-androgenic steroid users: A descriptive metasynthesis
(Peer reviewed; Journal article, 2015-03-15)Background As far as we are aware, no previous systematic review and synthesis of the qualitative/descriptive literature on polypharmacy in anabolic-androgenic steroid(s) (AAS) users has been published. Method We systematically ... -
Polyphonic Imagination: Understanding Idea Generation in Multidisciplinary Groups as a Multivoiced Stimulation of Fantasy
(Peer reviewed; Journal article, 2020)The primary objective of this paper is to offer a new way of understanding the creative processes of multidisciplinary groups, whose work is to generate innovative ideas. The paper reports from a project focused on ... -
Polyphonic perspectives: a focus group study of interprofessional staff’s perceptions of music therapy at an inpatient unit for children in mental health care
(Journal article; Peer reviewed, 2023)Purpose: In an inpatient unit for children in mental health care, a variety of services are provided through interprofessional collaborations. Music therapy is a relatively recent proposition in this context, but there is ... -

(Doctoral thesis, 2010-06-10)This dissertation attempts a discourse analysis of four African post-colonial novels pertaining to what has been named “roman de la rupture”, which refers to novels that have evolved from the sixties till date and depict ... -
Polyphonie et représentations dans la poésie orale africaine. Images et voix d’outre-mer chez F. Bebey et D. Elwood
(Master thesis, 2006-04-01)This study is about the white presence in francophone oral poetry from Africa south of the Sahara. The thesis uses polyphony and enunciation theories to attempt a study of the pictures and voices of the North in the works ... -
Polyphosphoinositides in the nucleus: Roadmap of their effectors and mechanisms of interaction
(Peer reviewed; Journal article, 2019)Biomolecular interactions between proteins and polyphosphoinositides (PPIn) are essential in the regulation of the vast majority of cellular processes. Consequently, alteration of these interactions is implicated in the ... -
