1. 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
2. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging
Master-uppsats, KTH/KemiSammanfattning : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. LÄS MER
3. Ion Induced Particle Desorption From Self Supporting Nanomembranes : Influence of Different Geometries and Particle Types
Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysikSammanfattning : Nanoelectronics is a field undergoing rapid development, meaning knowledge of the materials and methods used in nano-scale systems is a driving force in the industry. Silicon is a well known material in nanoelectronics commonly used as a semiconductor and is therefore a good representative for nanomaterials in general. LÄS MER
4. Investigation of Ion Extraction Anomalies at TwinEBIS
Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The electron beam ion source REXEBIS at CERN-ISOLDE delivers highly-charged ra- dioactive ions for post-acceleration in the HIE-ISOLDE LINAC. Research and develop- ment of components for electron beam ion sources is carried out at the TwinEBIS test stand, currently equipped with a Brillouin electron gun called MEDeGUN. LÄS MER
5. Effect of increased vertical stress on the state of grains in tailings
Master-uppsats, Luleå tekniska universitet/GeoteknologiSammanfattning : Tailings storage facilities (TSFs) serve as structures for storing tailings, i.e., waste materials generated by the mining industry. LÄS MER
