Proximity to high densities of pastoral settlements reduces grassland regrowth in a protected tropical savanna
(Journal article; Peer reviewed, 2021)Sedentarization of pastoralist communities is reshaping the structure and functioning of tropical savannas. Of particular concern is how permanent pastoral settlements change grassland vegetation inside “protected” areas. ... -
Proximity-Induced Superconductivity in CdTe-HgTe Core-Shell Nanowires
(Journal article; Peer reviewed, 2019)In this Letter we report on proximity superconductivity induced in CdTe–HgTe core–shell nanowires, a quasi-one-dimensional heterostructure of the topological insulator HgTe. We demonstrate a Josephson supercurrent in our ... -
Pseudo-T2 mapping for normalization of T2-weighted prostate MRI
(Peer reviewed; Journal article, 2022)Objective Signal intensity normalization is necessary to reduce heterogeneity in T2-weighted (T2W) magnetic resonance imaging (MRI) for quantitative analysis of multicenter data. AutoRef is an automated dual-reference ... -
Psychometric properties of the person-centred coordinated care experience questionnaire (P3CEQ) in a Norwegian radiotherapy setting
(Peer reviewed; Journal article, 2022)The number of older adults with cancer is increasing. Radiotherapy is an important treatment modality for cancer and may cause side effects and distress. Patient-reported experience measures aim to measure patients’ ... -
Psychophysics of reading and illumination needs during reading in visually impaired subjects with age-related macular degeneration
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:32, Doctoral thesis, 2005)The primary aim of this study was to contribute to a better understanding of how we can optimize reading conditions for subjects with age-related macular degeneration (AMD). In order to achieve this goal, we have developed ... -
Psychrobacter spp. from an Arctic marine environment: Versatile candidates for the degradation of phenolic compounds
(Doctoral thesis at NTNU;2016:133, Doctoral thesis, 2016)Phenol and its derivatives have challenged pollution/waste management due to being structurally recalcitrant to degradation processes. Bio-based processes continue to be the preferred choice for removal of phenols due to ... -
Public health implications of endocrine disrupting chemicals in drinking water and aquatic food resources in Nigeria: A state-of-the-science review
(Peer reviewed; Journal article, 2023)This state-of-the-science review is aimed at identifying the sources, occurrence, and concentrations of EDCs, including potential public health risks associated with drinking water and aquatic food resources from Nigerian ... -
Pulsed laser ablation and deposition of ZnS:Cr
(Journal article; Peer reviewed, 2015)We present a method to deposit films with a range of doping concentrations/dilute alloys, from a single target in pulsed laser deposition (PLD). Cr-doped ZnS films were deposited by ablating a target consisting Cr particles ... -
Pulsed Laser Deposited TiO2: X-Ray Diffraction and Raman Spectroscopy Studies
(Master thesis, 2022)Pulserende laserdeponerte TiO2-tynnfilmer har blitt undersøkt ved røntgen-diffraksjon (XRD) og ramanspektroskopi. Utvalget av TiO2-tynnfilmer bestod av både udopede og (Cr,N)-dopede filmer. Bakgrunnen for studien var å ... -
Pulsed Laser Deposition of Zinc Sulfide Thin Films on Silicon: The influence of substrate orientation and preparation on thin film morphology and texture
(Master thesis, 2014)The effect of orientation and preparation of silicon substrates on the growth morphology and crystalline structure of ZnS thin films deposited by pulsed laser deposition (PLD) has been investigated through scanning electron ... -
Pulsed laser growth of La2NiMnO6 for intermediate band solar cells
(Master thesis, 2022)Mellombåndssolceller har vist stort potensiale for å øke effektiviteten til fotoelektriske enheter, og samtidig redusere kostnaden knyttet til produsert elektrisitet. Funksjonelle oksidmaterialer, som doble perovskitter, ... -
Pump-probe experiments of multicrystalline silicon for solar cell applications
(Master thesis, 2012)In order to make cost effective solar cells from mc-Si materials, the negative contributions from defects and impurities should be reduced. The analysis of the photogenerated carrier properties is therefore of great ... -
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 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 ... -
Purification and characterization of an unusual DNA glycosylase in diatoms
(Master thesis, 2012)DNA damage may be caused by many different agents, including radiation, spontaneous mutations and chemical mutagens. If the damage is left unrepaired, it may result in mutations or cell death. All organisms contain repair ... -
