1. Emergent spacetime from simple field theories
Sammanfattning : Thermalization is an elusive phenomenon in quantum mechanics. Since according to the AdS/CFT correspondence, a black hole in the bulk spacetime is dual to a thermal state in the boundary CFT, thermalization in the CFT is dual to black hole formation in AdS. LÄS MER
2. Studies of flow and heat transfer in as quenching : quench chambers, impingement, cooled bodies, and inverse solutions
Sammanfattning : .... LÄS MER
3. Quench-Condensed Metallic Clusters Studied by Single Electron Tunneling
Sammanfattning : Using angle deposition through conventional electron-beam lithographic masks as the sample resistance was measured in situ, we defined constrictions with widths and lengths of about 5 nm in thin (1-3) nm granular films. The nominal film thickness in the constriction could be varied stepwise by in situ film depositions, changing the grain size and the configuration of the tunneling paths. LÄS MER
4. Effects of Varying Combustion Conditions on PCDD/F Formation
Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. LÄS MER
5. Thermal formation and chlorination of dioxins and dioxin-like compounds
Sammanfattning : This thesis contributes to an increased understanding of the formation of dioxins and dioxin-like compounds in combustion processes. Although emissions to air from waste incineration facilities have been greatly reduced by the use of efficient air pollution control measures, the resulting residues (ashes and filters) are highly toxic and are classified as hazardous waste.
