Pulseless electrical activity in in-hospital cardiac arrest – A crossroad for decisions
(Journal article; Peer reviewed, 2022) -
Pump-Turbines in Conventional Hydropower Plants
(Peer reviewed; Journal article, 2021)This paper proposes an innovative approach to retrofit existing hydropower plants with suitable upper and lower reservoirs into pumped storage. The conventional methods are both comprehensive and expensive, mainly due to ... -
Pumping of concrete and Mortar - State of the art
(COIN Project report;5-2008, Research report, 2008)The pumpability of concrete, or its ability to move through pipes and hoses by the help of a pump while maintaining its fresh and hardened properties, can be quantified as being better the lower the necessary pressure to ... -
Punctuality development and delay explanation factors on Norwegian railways in the period 2005–2014
(Peer reviewed; Journal article, 2021)The paper revisits an investigation of delays and punctuality on Norwegian railroads from 2010, re-evaluating its findings and studying the effects of later measures put in place between 2010 and 2014. Norwegian railways ... -
Punctuation and extrapolation: representing a subsurface oil reservoir
(Journal article; Peer reviewed, 2012)This article discusses how data are made to represent subsurface phenomena in petroleum production. Drawing on studies of the subsurface disciplines in an oil company, and the multitude of sensor data employed there, we ... -
Punishment justifications in rape cases: a community study
(Journal article; Peer reviewed, 2017)Norway is one of the countries with the most progressive criminal justice systems in the Western world. Traditionally, the Norwegian criminal justice system has been mainly based on treatment and deterrence perspectives. ... -
Pupils’ use of social media and its relation to mental health from a school personnel perspective: A preliminary qualitative study
(Peer reviewed; Journal article, 2021)The extent of mental health problems among adolescents seems to be on the rise, and this observed trend has often been linked to a coinciding increase in social media use. The goal of the current preliminary study was to ... -
Pure and Zr-doped YMnO3+δ as a YSZ-compatible SOFC cathode: a combined computational and experimental approach
(Journal article; Peer reviewed, 2019)A thorough study of the Y1−xZrxMnO3+δ series is presented with the objective to use these materials as SOFC cathodes. These pure and Zr-doped yttrium manganites exhibit a layered hexagonal structure similar to a peculiar ... -
Pure Mode I Fracture Toughness Determination in Rocks Using a Pseudo‑Compact Tension (pCT) Test Approach
(Journal article, 2020)Mode I fracture toughness (KIC) quantifies the ability of a material to withstand crack initiation and propagation due to tensile loads. The International Society for Rock Mechanics (ISRM) has proposed four suggested methods ... -
Pure spin current generated by reflection at a normal metal/two-dimensional electron gas interface
(Journal article; Peer reviewed, 2010)The concept of a spin current is a useful tool in understanding spin transport in hybrid systems but its very definition is problematic in systems where spin-orbit coupling effects are strong. In the absence of spin-dependent ... -
Pure-minimal chain complexes
(Journal article; Peer reviewed, 2019)We introduce a notion of pure-minimality for chain complexes of modules and show that it coincides with (homotopic) minimality in standard settings, while being a more useful notion for complexes of flat modules. As ... -
Purely infinite crossed products by endomorphisms
(Journal article; Peer reviewed, 2014)We study the crossed product C*-algebra associated to injective endomorphisms, which turns out to be equivalent to study the crossed product by the dilated automorphism. We prove that the dilation of the Bernoulli p -shift ... -
Purification of High-grade Calcite Ore by Flotation with Alkyl Diamines
(Peer reviewed; Journal article, 2018)A very high-grade calcite deposit located in northern Norway consists of CaCO3 ore with minor silicate and sulphide impurities. Cationic (Tallow-1,3-diaminopropane, Duomeen T) collector has been used in the purification ... -
Purity or perversion? from taboo to fact: kindergarten teachers’ reflections on age-normal sexuality
(Peer reviewed; Journal article, 2023)Many educators and pedagogues around the world face challenging situations in their everyday work. Being caught off guard when children begin to explore their bodies and show curiosity about body parts and sexual issues ... -
Pushe eller puse - perspektiver på dramarommets paradoks
(Journal article; Peer reviewed, 2023)I denne artikkelen presenteres funn fra en studie på programfag drama i norsk videregående skole. Dramalærere samt tidligere og nåværende dramaelever fra tre skoler ble intervjuet om hvordan de så på forholdet mellom ... -
Pushing Boundaries: Reflections on Teaching and Learning Contemporary Dance in Amman
(Journal article; Peer reviewed, 2013)This study reflects on teaching and learning contemporary dance in Amman, Jordan, focusing on the experiences of three contemporary dance students. Through the three case studies, various issues regarding teaching and ... -
Pushing the limits of beam-steering lens arrays
(Journal article; Peer reviewed, 2019)An essential part of a concentrated solar power system is the solar tracker. Tracking is usually implemented by rotating the entire optical system to follow the sun, adding to the bulk and complexity of the system. ... -
Put your weight behind it—Effect of body mass index on the active second stage of labour: A retrospective cohort study

Putting Temperature into the Equation: Development and Validation of Algorithms to Distinguish Non-Wearing from Inactivity and Sleep in Wearable Sensors
(Peer reviewed; Journal article, 2022)Long-term monitoring of real-life physical activity (PA) using wearable devices is increasingly used in clinical and epidemiological studies. The quality of the recorded data is an important issue, as unreliable data may ... -
PVA-assisted combustion synthesis and characterization of porous nanocomposite Li2FeSiO4/C
(Journal article; Peer reviewed, 2012)Porous Li2FeSiO4/C nanocomposites were synthesized by a PVA-assisted combustion method, and phase pure Li2FeSiO4 was produced for samples prepared with 20 and 30 wt.% starch. The electrochemical properties of the Li2FeSiO4/C ...
