1. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. LÄS MER
2. Kan underhållsrutiner effektiviseras utifrån oljekvalité?
Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)Sammanfattning : En undersökning av vindturbiners hydraulolja med avseende på partikelinnehåll har genomförts. Med syftet att öka tillgängligheten på Statkrafts vindturbiner genom ändrade underhållsrutiner. Målsättningen har varit att minska mängden partiklar och hitta en lösning för förbättrat underhåll rörande hydrauloljan. LÄS MER
3. Thermal neutron counting and gamma-ray peak identification from fusion reactions, using a Sodern Genie-16 Neutron Generator
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : This thesis work focuses on the categorisation of a Sodern Genie-16 Neutron Generator, at the Nuclear Applications Laboratory, Lund University. To that end, the goals of this work focuses on the re-development of the pre-existing infrastructure surrounding the Sodern Genie-16 Neutron Generator for the purposes of internally irradiating samples, and the subsequent categorisation of the new configuration for extraction of fast neutrons.

4. Gap properties of helical edge states in two-dimensional topological insulators with time-dependent magnetic impurities
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenSammanfattning : The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics. A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect. LÄS MER
5. Photodegradation of macroplastics to microplastics : A laboratory study on common litter found in urban areas
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : During the last 60 years the plastic production has increased more than 190 times and plasticpollution both at sea and land is a growing issue. Every year millions of tons of plastic waste fromland reaches the oceans, but the land-based sources are diffuse. LÄS MER
