Cross-Cultural Adaptation and Psychometric Properties of the Swahili Version of the European Organization for Research and Treatment of Cancer (EORTC) QLQ-BR45 among Breast Cancer Patients in Tanzania
(Peer reviewed; Journal article, 2023)Breast cancer is the most frequent cancer in women in Africa and contributes to premature death and poor quality of life. This study aimed to determine the validity, reliability, and psychometric properties of the Swahili ... -
Cryogenic temperature deformation behaviour of two Al-Mg-Si alloys
(Doctoral theses at NTNU;2017:11, Doctoral thesis, 2017)A comprehensive study was carried out to clarify the effects of cryogenic temperature on mechanical properties and microstructure of two peak-aged Al-Mg-Si profiles, i.e., fully recrystallized AA6060 and fibrous AA6082. ... -
Cryogenic vs. absorption biogas upgrading in liquefied biomethane production – An energy efficiency analysis
(Journal article; Peer reviewed, 2019)Production of liquefied biomethane (LBM) from biogas comprises two major energy intensive processes; upgrading to increase the methane concentration and refrigeration to liquefy the upgraded biogas. Amine-based absorption ... -
Crystal Orientation of Iron Produced by Electrodeoxidation of Hematite Particles
(Journal article, 2013)Electrowinning of iron was conducted in a 50 wt% NaOH-H2O electrolyte with suspended Fe2O3 particles at 110ºC and pure α-Fe films were obtained on a disk cathode with a higher current efficiency than 95%. The Fe2O3 particle ... -
Crystal Phase Mapping by Scanning Precession Electron Diffraction and Machine Learning Decomposition
