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

In times when dwindling energy resources is a major long-term problem for sustaining modern infrastructure and technologies, we need to focus on more enduring solutions. A key contribution to this achievement is catalysis. In order to further develop the significant advancements gained over the last several decades, a deeper understanding of the catalytic processes has to be sought down to the lev

The complex character of rural landscapes implies a constant interaction between mind and matter as well as between nature and society. In landscapes, the established division of reality into nature and culture appears all but natural. This book points to the possibilities of regarding landscape as a dialectical process. Landscape is here used as an analytical device to examine nature-culture rela

Arbuscular mycorrhizal (AM) fungi colonise a wide range of plant species and are especially common in soils with a relatively high pH, where phosphorus availability is a limiting factor for primary production. The aim of this thesis was to study the ecophysiology of arbuscular mycorrhizal (AM) fungi when exposed to different environments. Development of AM fungi and their host plants were investig

Optimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. Two methods are used and further developed; fulfilment of image criteria (IC) and visual grading analysis (VGA). Clinical image quality de

The emergence of markets for online physician consultations -- direct-to-consumers telemedicine (DCT) -- is transforming healthcare services in many nations. The convenience of DCT lowers the cost of seeking care, thus potentially increasing demand. Yet, it is not known whether patients consuming online care turn to traditional providers as well. This is one of the first studies to causally assess

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

The aim of this thesis was to study outcome and evaluation of rheumatological multidisciplinary team rehabilitation programmes in patients with chronic inflammatory arthritis (CIA); rheumatoid arthritis (RA), ankylosing spondylitis, psoriatic arthritis and other spondyloarthritides, and to analyse health care utilization over the last decade in patients with RA. In Study I the outcome of an 18 da

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

We address the problem of the dissipative character of collective motion in finite Fermi systems. We study this problem from the point of view of chaotic features of the fermionic degrees of freedom of the many-body Fermi systems. Our main aim is of two kinds: first, we investigate how quantum chaos sets in in many-body systems and then, we try to relate quantum many-body chaos of the intrinsic fe
