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
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
In this thesis, I have studied in situ the resource economy of the three carnivorous plant species Pinguicula alpina, P. villosa and P. vulgaris in a subarctic environment. The prey capture varied among individual plants, years and species. It was higher in young leaves then in old ones. P. vulgaris captured more prey that the other species and reproductive individuals of P. vulgaris captured more
The dissertation focuses on the Haredi (ultra-orthodox Jewish) journal The Jewish Observer, published since 1963 by Agudath Israel of America, suggesting that the publisher uses the journal as an instrument to help the readers to maintain a distinct Haredi identity in urban, non-Haredi environments and not only in their own, isolated milieu. The articles of the journal are understood as resources,
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
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
Since 1991 cleaner production projects have been pursued by the donors in Eastern European industry. These projects have aimed at demonstrating the benefits of a preventive approach to environmental protection, and to train people within the industry to perform the cleaner production assessments that constitute the core element of the preventive approach. The large merit of the preventive approach
Tourism has become a leading industry in the world and continues to grow rapidly, contributing essentially to economic growth and employment in many countries. Tourism as it looks today poses serious threats to the environment and considerable social and cultural challenges. The problem addressed by this research lies in the weakness of current concepts and practices in pursuit of sustainable tour
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
