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 ... -
PVA/nanocellulose nanocomposite membranes for CO2 separation from flue gas
(Peer reviewed; Journal article, 2019)In this paper, we explore the use of nanocelluloses as an additive to poly (vinyl alcohol) (PVA) nanocomposite membranes for CO2/N2 mixed-gas separation. Our findings are that several types of nanocellulose can be used to ... -
PVA/PVP blend polymer matrix for hosting carriers in facilitated transport membranes: Synergistic enhancement of CO2 separation performance
(Journal article; Peer reviewed, 2019)CO2 separation performance in facilitated transport membranes has been reported depended not only on the CO2 carrier properties but also to a great extent on the polymeric matrix regarding the capacity of retaining water ... -
PVTx Modeling of CO2 Pipeline at Depressurization Conditions Using SPUNG Equation of State (EoS) with a Comparison to SRK
(Journal article; Peer reviewed, 2014)The proper modeling of CO2 depressurization is very important for the design for safety of a pipeline. One key element of the modeling process is the thermodynamics and transport properties modeling. In this work, an ... -
PWM investigation of a Field-oriented controlled Five-Phase PMSM under two-phase open faults
(Peer reviewed; Journal article, 2020)The decoupled model of Five-Phase Permanent Magnet Synchronous Motors (5Ph PMSMs) under a two-phase open circuit has been developed recently, yet the corresponding PWM has not been fully exploited. The Pulse Width Modulation ... -
