The evolutionary history of the allotetraploid Arabidopsis suecica and its maternal parent Arabidopsis thaliana is analyzed in the thesis in terms of genetic variation in the natural populations of the two species. The earliest phase of the speciation event in which the genomes of A. thaliana and A. suecica are in the process of diverging was investigated using population genetic methods. Evolutio

The thesis addresses different questions, each necessary in the understanding of dynamic fracture initiation and crack propagation in steel. Emphasis lays on dynamic crack propagation experiments performed in the ductile to brittle transition region and possible conclusions, that can be drawn from them. One question regards the physical basis for for viscoplasticity. Dislocation slip by thermal a

Using optical spectroscopy, nuclear magnetic resonance (NMR), and differential scanning Calorimetry (DSC), I have studied two different calcium binding proteins that can form kinetically trapped altered states. Calcium is very important in numerous biological processes such as blood coagulation, signal transduction, muscle contraction and bone formation. Calcium binding to proteins regulates these

There is a strong desire for short wavelength (~1 Å), short pulsewidth (<100 fs), high-brightness, transverse and longitudinally coherent light pulses for use by the synchrotron radiation community. These requirements exceed the limits achievable by existing, so-called, "third-generation" light sources, such as the Advanced Photon Source (APS) at Argonne National Laboratory (ANL), USA, the Europea

British film critic Robin Wood began to publish on film in 1960. Since then, he has written or co-written 13 books, and also published hundreds of essays and articles in books, in journals, and in different encyclopedias. At the same time, Wood has been a key figure in the development of what has become academic film studies. Wood was educated at Cambridge University, where he studied English lite

This thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. A feedback scheduling strategy is presented, which uses feedback from plant states to distribute computing resources optimally among a set of co

The main purpose of this thesis is to study real exceptional Kantor triple systems. In the first paper we first prove the known results in both the real and complex classical cases of K-simple Kantor triple systems. In the real classical case our approach gives somewhat simpler formulas. Special attention is given to all real classical cases of K-simple Kantor triple systems that can be presented

The chaebol conglomerates, which constituted the backbone of the "South Korean miracle", became the instrument for economic growth within a framework laid down by the "developmental state". With a minimum of own capital, but with private owner-control and loan-financing, these chaebols were able to expand. How could this "impossible" configuration survive? The thesis analyses how this could contin

In this dissertation, young men's experiences of being victims of crime are analysed. Several kinds of material are considered in this study, but the primary data consist of informal, tape-recorded interviews with ten young men (17 to 21 year's old) who had been assaulted or mugged. Their accounts of their experiences are analysed using a number of constructionist, interactionist, and narrative pe

Complex biological and environmental samples require a high degree of selectivity in order to determine components therein. Sensitivity measures, such as analyte pre-concentration are often required for assessing composition quantitatively. Use of membranes and especially non-porous membranes for extraction purposes offers in many cases the desired measure of selectivity and sensitivity for trace

European agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. Such changes in climate could also affect the population dynamics of insect pests. The Colorado potato beetle (CPB) is o

Value-based management has attracted considerable interest among organizations and academics in recent years. Responding to calls for case-based research, this thesis describes, analyses and conceptualizes value-based management as a management accounting construct. While previous research has focused on the measures (eg. EVA) advanced in the normative literature, this analysis demonstrates that

The main objective of this work was to construct practical analytical systems for the analysis of environmental and biological samples, using membrane-based techniques for sample pretreatment and chromatography for final analysis. Two types of membrane processes have been applied, with emphasis on automation. The supported liquid membrane (SLM) extraction was carried out in an automated continuou

This thesis is about the residents and employees at three group homes for older people suffering from dementia. The empirical data comprises princi- pally of participant observation and interviews with caregivers. The aim of the dissertation is to describe and understand what happens during daily life at a group home for elderly suffering from dementia. The ambition is to understand the patterns o

In the course of my dissertation work, I have sought knowledge about what New Age is, contains, and conveys by looking at practice and rhetoric, how the participants act and reason regarding their commitment, as well as how the contents of the field is discussed. I have put an emphasis on the small details: the objects, the rituals, and the narrating. Using the tarot cards as a starting point, the

The aim of the study is to improve the understanding of strategy in politically governed organisations. From the perspective of a specific responsible authority the main purpose of the study is to describe and analyse how strategies emerge and develop. Competitive tendering and inter-municipal co-operation, has been studied as a two principally different strategic approaches to reduce costs and st

The objective of the present work was to investigate the mixing process in static mixers under laminar flow conditions, and in pipes during the displacement of dissimilar liquids. A numerical scheme and a method of characterizing static mixers were developed. The effects of changes in geometry, flow rate, viscosity ratio and volumetric flow rate ratio on the mixing process were investigated using
