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
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
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
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
In this thesis, we give a description of the detailed structure of the proton and a description of the final-state properties in electron-proton scattering. Qualitative results, in a purely gluonic scenario with the leading log approximation, and quantitative results, where quarks are included and some sub-leading corrections have been made, are presented. The quantitative results are in fair agre
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
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
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
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
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
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
Potts mean field artificial neural network techniques are developed and applied to airline crew scheduling problems and routing problems. A propagator formalism in terms of Potts neurons is developed to handle global topological issues. An integrated method for identifying and classifying ECG complexes is presented. Unsupervised self-organizing artificial neural networks are employed to cluster t
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
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
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 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 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 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
This study describes, systematizes and analyses the variations of preachers' conceptions of their mission to preach and their listeners' conceptions of the sermon. It does so in a phenomenographic and theological perspective. The conceptions of preachers and their listeners of the mission to preach and the sermon respectively are investigated by way of interviews. The basic issues are what differe
