1. Triaxialförsök och utvärdering av parametrar för modellering : Anrikningssand med sprött beteende
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/GeoteknologiSammanfattning : Efter det dammbrott som skedde vid Brumadinho i Brasilien under januari 2019, där hundratals människor miste sina liv, har frågor kring statisk liquefaction hos anrikningssand fått stort fokus inom gruvdammsindustrin. Statisk liquefaction kan modelleras med den konstitutiva modellen NorSand, där NorSand-parametrarna kan utvärderas från triaxialförsök. LÄS MER
2. Implementation of Dyson equation to accelerate convergence in RS-LMTO-ASA code
Master-uppsats, Uppsala universitet/MaterialteoriSammanfattning : First-principle calculations is a key ingredient for us to understand, improve and design new materials. Density functional theory (DFT) [1] has proven to be a very powerful tool and a number of different versions exist depending on the problem at hand. LÄS MER
3. Prospects for a Free Electron Laser at the FemtoMAX Beamline
Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenSammanfattning : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

4. Investigation of Ice Nucleating Particles (INPs) in southern Sweden - With a special focus on their origin, possible connection to meteorological parameters and aerosol properties
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : This study investigates if there is a seasonal variability of ice nucleating particle (INP) concentrations. There is also a focus in seeing if there are correlations between meteorological parameters and aerosol properties and the measured INP concentrations. LÄS MER
5. Refining the particulate matter airway deposition arising from indoor cooking-related biomass combustion for children in the Haramaya district in Ethiopia
Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologiSammanfattning : Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. LÄS MER
