Fluidised bed thermal gasification of biomass is an effective route that results in 100 % conversion of the fuel. In contrast to chemical, enzymatic or anaerobic methods of biomass treatment, the thermal conversion leaves no contaminated residue after the process. The product gas evolved within thermal conversion can be used in several applications such as: fuel for gas turbines, combustion engine

An important measure for climate change mitigation is reduction of energy use in buildings worldwide. To decrease the energy use of a building in a Nordic climate, increased thermal resistance of the building envelope is a suitable measure. Adding more insulation in combination with climate change may increase the risk of mold growth within the building envelope. This study evaluates hygrothermal

A fundamental function of long-term memory is the ability to retrieve a specific memory when encountering a retrieval cue. The purpose of this dissertation was to further our understanding of such cued recall by investigating the temporal dynamics from the presentation of the retrieval cue until the target memory is recalled. Retrieval cues are often related with several memories. When such a retr

Popular AbstractStudien är ett försök att analysera den sociala konstruktionen av "medievåld" i den svenska pressdebatten 1980-1995. Totalt analyserades 1029 artiklar ur sju av Sveriges största dags- och kvällstidningar. Många artiklar refererar till vetenskapliga "bevis" att våld i medierna föder faktisk aggression. En närmare analys av medieeffektforskningen avslöjar dock att det påstådda samban

Many microorganisms have developed mechanisms to protect themselves against attack from the complement system of the host. One possible mechanism for a microorganism to evade complement attack is to bind a human complement regulator, which may allow the microorganism to down-regulate complement activation. This thesis describes studies of such interactions between human C4b-binding protein (C4BP),

Background. Infections are the most commonly reported health problems in children. Younger age and day care outside the home are two factors of importance for infectious morbidity. The influence of siblings on infectious symptoms is not clear. Objectives. To compare families with one child and families with more than one child in terms of reported infectious symptoms, physician consultations and a

A cost-efficient way to increase power in a genetic association study is to pool controls from different sources. The genotyping effort can then be directed to large case series. The Nordic Control database, NordicDB, has been set up as a unique resource in the Nordic area and the data are available for authorized users through the web portal (http://www.nordicdb.org). The current version of Nordi

The focus of this thesis was to study cytogenetic and molecular genetic aberrations in lipomas. For this purpose, chromosome banding analysis, fluorescence in situ hybridization (FISH), as well as high resolution single nucleotide polymorphism (SNP)–arrays were used to identify recurrent chromosomal aberrations in lipomas. The possible molecular targets for these aberrations were further studied t

This thesis describes investigations of the use of cryogenically cooled rare-earth-ion-doped crystals for quantum information processing and quantum optics. Several aspects of the coherent interaction between light and rare-earth ions in solids are addressed. Quantum information science has given physicists new views of quantum mechanics. The transmission of quantum states has already found pract

This thesis deals with various aspects of growth, convergence and technological change, all analysed from an empirical perspective. A common theme throughout the six chapters is the analysis of economic historical questions of productivity growth with the use of quantitative statistical techniques. An introductory chapter is followed by two chapters on the Western European regional growth and conv
