Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : The Swedish Institute of Space Physics (IRF) at Kiruna focuses on research activities in the ionosphere, magnetosphere, and upper atmosphere of the planet as well as the development and production of various sensors and detectors for space research. The test facility includes the IRF SpaceLab which is equipped with multiple testing equipment. LÄS MER
7. Lead Concentrations in Indoor Dust : Differences Between Indoor Shooting Ranges and Assumed Non-Lead Contaminated Sites
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : A projectile which missed its target and falls into the bullet trap at the end of the shooting range might not be viewed as dangerous. Yet, hazardous fumes and fine metal fragments from the bullet might contaminate the users of the shooting range. LÄS MER
8. Feasibility Study on Additive Manufacturing of Copper Windings using Electron Beam Melting
Master-uppsats, KTH/ProduktionsutvecklingSammanfattning : Within the framework of this thesis, the electron beam melting of pure copper for the purpose of producing electrical windings was examined. The conventional manufacturing process of copper windings was investigated, and the potential advantages offered by the design freedom inherent in the electron beam melting process were explored.

9. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.
