Picking up the Pieces : Contextualizing Utilized Blade Fragments from Two Assemblages in Southwest Norway
(Peer reviewed; Journal article, 2020)This article centers on a discussion of blade fragments from two Late Mesolithic assemblages recovered during a recent excavation project in Rogaland, southwest Norway. Analysis undertaken during post excavation cataloging ... -
Pigment identification during deetiolation of barley seedlings
(Masteroppgave/UIS-TN-IMN/2012;, Master thesis, 2012)Angiosperm plants like barley (Hordeum vulgare) lack chlorophyll when grown in complete dark. Upon exposure to light, chlorophyll is formed during the process of deetiolation. Here , we show that in complete darkness barley ... -
Pilot scale testing of salsnes filter (SF500) for biofilm solids removal from a full scale wastewater treatment plant
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-07-15)This thesis investigated the performance of Salsnes Filter (SF) as a secondary treatment after biological treatment processes at Nordre Follo Renseanlegg (NFR) wastewater treatment plant. Wastewater from moving ... -
Pilot-scale study to investigate the impact of rotating belt filter upstream of a MBR for nitrogen removal
(Peer reviewed; Journal article, 2019-02)The goal of this study was to investigate what kind of impact the removal of particulate organic matter with 33μm rotating belt filter (RBF) (as a primary treatment) will have on the membrane bioreactor (MBR) performance. ... -

Pilots on the Norwegian continental shelf; from a contractual and decision making standpoint
(Masteroppgave/UIS-TN-IØRP/2011;, Master thesis, 2011)This thesis consists of two different parts which investigates two different things, but with the same topicality in focus. The superior aim of the thesis is to enlighten potential project stoppers with regards to technology ... -
Pinpointing regulatory protein phosphatase 2A subunits involved in beneficial symbiosis between plants and microbes
(Peer reviewed; Journal article, 2021-04)Background PROTEIN PHOSPHATASE 2A (PP2A) expression is crucial for the symbiotic association between plants and various microbes, and knowledge on these symbiotic processes is important for sustainable agriculture. Here ... -
Pion condensation and phase diagram in the Polyakov-loop quark-meson model
(Journal article; Peer reviewed, 2018-10)We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study the phase diagram in the μI–T planewhere μI is the isospin chemical potential. In particular, we focus on the ... -
Pion condensation and QCD phase diagram at finite isospin density
(Journal article; Peer reviewed, 2019-09)We use the Polyakov-loop extended two-flavor quark-meson model as a low-energy effective model for QCD to study 1) the possibility of inhomogeneous chiral condensates and its competition with a homogeneous pion condensate ... -
Pipe Viscometer for Continuous Viscosity and Density Measurement of Oil Well Barrier Materials
(Peer reviewed; Journal article, 2023)The barrier material is a crucial component for wells, as it provides mechanical support to the casing and prevents the uncontrolled flow of formation fluids, ensuring zonal isolation. One of the essential prerequisites ... -
Pipelay with Residual Curvature
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-06-15)Offshore pipelines under operating loads, i.e. under high temperature and pressure, are exposed to expansion and compressive forces, which may cause the pipeline to buckle globally. If significant lateral motion and excessive ... -
