1. Accelerator-driven systems : source efficiency and reacitvity determination
Abstract : Accelerator-driven systems (ADS) are being investigated and designed for transmutation of the long-lived nuclear waste. Application of ADS allows to safely transmute large fractions of minor actinides (MA) per reactor core, while the fraction in critical reactors is limited to a few percent due to the safety constraints.

2. Experimental Determination of Aeracoustic Sources in Low Mach Number Internal Flows
Abstract : In this thesis, the in-duct experimental methods for determining aeroacoustic N-ports of in-duct elements are discussed and improved. The scattering matrix determination methods and the related wave decomposition methods are evaluated from measurements in an empty duct carrying a mean flow. READ MORE

3. Analyses and Application of Ambient Seismic Noise in Sweden : Source, Interferometry, Tomography
Abstract : Ambient seismic noise from generation to its application for determination of sub-surface velocity structures is analyzed using continuous data recordings from the Swedish National Seismic Network (SNSN). The fundamental aim of the thesis is to investigate the applicability of precise velocity measurements from ambient noise data. READ MORE

4. From source to the environment : Strategies for identification and determination of hydroxylated polycyclic aromatic hydrocarbons in complex particulate matrices
Abstract : Adverse health effects have been linked to exposure to particulate matter, and wood combustion is considered as an important source of harmful particulate matter in the urban air and environment. Hydroxylated polycyclic aromatic hydrocarbons are a group of compounds with toxic, endocrine disrupting and carcinogenic properties. READ MORE

5. The Emergence of Conditional Subordinators in Swedish : A Study in Grammaticalization
Abstract : This thesis is an empirical and theoretical study of the emergence of five Swedish conditional subordinators: utan, om, hvar, ifall and bara. The first changes occur in the 13th century, and the last in the 18th century. READ MORE
