Investigation of glitches induced by single-crystal diamond compound refractive lenses based on crystal orientation
(Peer reviewed; Journal article, 2019)Single-crystal diamond is considered as an ideal material for compound refractive lenses (usually abbreviated to “CRLs”) mainly due to its stability when bathed in strong X-ray radiation. Since CRLs come into operation by ... -
Investigation of growth performance of post-smolt Atlantic salmon (Salmo salar L.) in semi closed containment system: A big-scale benchmark study
(Peer reviewed; Journal article, 2022)The Norwegian salmon industry faces challenges related to sea lice (Lepeophtheirus salmonis) infestations, escapees, diseases and environmental impact. Semi-closed containment systems (S-CCS) have been proposed to abate ... -
Investigation of Influence of Adjustments in Cyclist Arm Position on Aerodynamic Drag Using Computational Fluid Dynamics
(Peer reviewed; Journal article, 2020-06)In professional cycling, even small adjustments in position could mean that valuable seconds are gained over the course of a time-trial race. This study investigates the influence of arm position on the aerodynamic drag ... -
Investigation of mechanical properties of false banana/glass fiber reinforced hybrid composite materials
(Peer reviewed; Journal article, 2020)The objective of the work presented in this article is to investigate the mechanical properties of false banana/glass fiber reinforced hybrid composite materials at different fiber volume fractions and orientation of hybrid ... -
Investigation of perioperative work processes in provision of antibiotic prophylaxis: a prospective descriptive qualitative study across surgical specialties in Norway
(Journal article; Peer reviewed, 2019-06)Abstract Objective: Surgical site infections are known postoperative complications, yet the most preventable of healthcare-associated infections. Correct provision of surgical antibiotic prophylaxis (SAP) is crucial. Use ... -
Investigation of Rotor Efficiency with Varying Rotor Pitch Angle for a Coaxial Drone
(Peer reviewed; Journal article, 2022-04)Coaxial rotor systems are appealing for multirotor drones, as they increase thrust without increasing the vehicle’s footprint. However, the thrust of a coaxial rotor system is reduced compared to having the rotors in line. ... -
An investigation of teacher’s practices when teaching mass measurement in grade 4 in Malawi
(Chapter, 2022)This paper reports on a study on teachers’ practices when teaching mass measurement in grade 4 in Malawi. Data was collected from video recordings of three grade 4 teachers (two lessons each) who were purposively sampled ... -
Investigation of the Antiscaling Performance of Phosphonated Chitosan for Upstream Petroleum Industry Application
(Peer reviewed; Journal article, 2021)Scale deposition is one of the main water-based production problems in the upstream oil and gas industry. Few environmentally friendly scale inhibitors show good thermal stability as well as calcium compatibility. We report ... -
Investigation of the Effect of Fracturing Fluids on Shale Pore Structure by Nuclear Magnetic Resonance
(Peer reviewed; Journal article, 2023)Hydraulic fracturing technology significantly enhances the productivity of shale oil and gas reservoirs. Nonetheless, the infiltration of fracturing fluid into shale formations can detrimentally affect the microscopic pore ... -
An investigation of the effects and consequences of combining Expanding Dual Pin with radial spherical plain bearings
(Peer reviewed; Journal article, 2022)An expanding pin locks the pin assembly to its supports and bearings and prevents any relative movements between the surfaces in contact. In this study, the diameter changes of the bearing inner ring as a function of the ... -
