A search for new physics using events with a single photon and missing energy has been made at the DELPHI experiment together with a search for charginos. The results were based on data collected up to and including the final year of 2000. An integrated luminosity of 650 pb^-1 was used in the single photon analysis and 450 pb^-1 in the chargino search. Center-of-mass energies up to 209 GeV were ex

In this thesis, methods to determine the static postbuckling behaviour of elastic structures undergoing large deformations, are considered and developed. Since the governing non-linear equations usually becomes too complex to be handled analytically, the main focus has been on developing methods that can be incorporated into a numerical solution scheme, such as the finite element method. First me

Consumers today are constantly showered with a vast array of different messages about what and how they should and should not eat in order to lead a healthy life. This bombardment has escalated over the last decades as various actors, such as representatives from the medical community and public policy makers, have increasingly stressed the connections between individuals’ food consumption habits

This dissertation addresses the design of value productive episodes at the customer/firm boundary. Its purpose is: To provide perspective and help articulate strategies for increasing precision of the design of interactive marketing and value productive efforts at firm/customer boundaries. Many observers, thinkers and practitioners of marketing and management are: (1) Struggling to comprehend and

Redox reactions are central to all organisms to sustain life. Both anabolic and catabolic metabolism depends on them. It is thus vital to sense and adjust the redox balance in the cell. One major factor affecting the redox status is the level of oxygen present. Transitions between different oxygen concentrations change the redox status and among other things, confer a stress upon the cells. This s

This study is characterized by its development of an analytical framework for describing and explaining the lender-borrower financing relationships of rural-based small and cottage industries by including contextual conditions. It applies this framework to the socio- environmental conditions of Bangladesh with special emphasis on the role of Islamic banks. A theoretical framework based on institu

The German poet Jacob Balde (1604-1668) chose a biblical human sacrifice as subject for his tragedy "Jephtias" intended to be performed at a Jesuit school. Jephthah, the judge, had to sacrifice his own daughter due to a vow given before the war against the Ammonites. Balde uses this topic to exemplify Jesuit virtues such as obedience, ability to handle one's emotions and readiness to sacrifice one

Investigations of astrophysical spectra require accurate atomic data, such as wavelengths and transition probabilities. This thesis provides high-precision atomic data for astrophysical and cosmological applications. The measurements have been carried out using Fourier transform spectrometry on light produced in a hollow cathode light source. The variability of fundamental constants is investigat

This book presents a study on general and specific problems concerning the role, functions and structure of criminal justice systems. After a presentation of some ideological and methodological issues, the justifications for different principles of criminal jurisdiction are discussed, both in the perspective of public international law and municipal law. The constituent elements of criminal offenc

The aim of this study was to expand our understanding of the processes of institutionalisation both within and between organisational fields. This was done by tracing an idea – the idea of quality assurance – through the process of institutionalisation in the health care sector. The new institutional theory, which focuses on the relation between organisations and the institutions they are consider

Ultrafine particles, their sources and fate in the atmosphere are currently key issues in atmospheric research owing to concern about their effects on human health and global climate. Traffic emissions are a dominating source of ultrafine particles, especially in urban areas. After release into the atmosphere, the particles are subjected to complex dilution and transformation processes that are of

This thesis treats the problem of transient electromagnetic pulse propagation in temporally dispersive media. The analysis is performed using time-domain techniques. In particular, the dispersive wave splitting which decouples the Maxwell equations both in vacuum and inside the medium is utilized. Complex time-dependent electromagnetic fields are introduced. These fields simplify the Maxwell equat

The thesis investigates the theoretical background and the research context within which interpretations of the Nordic Bronze Age have been formed in Scandinavian archaeology. A theoretical analysis that emphasises theories of social practice and phenomenological perspectives is presented. The purpose of the analysis is to explore theories of social practice as tools for grasping the dynamic relat

The main objective in the research described in this thesis was to design and test the use of lean premixed combustion using combustion gas recirculation for gas fuelled Stirling engine combustors. A system using a flame-arrester type of flame-holder to stabilize the flame and an ejector system for the recirculation of combustion gas was designed and tested in the laboratory. The impact of changes

It is difficult for states to cooperate on issues related to international peace and security. Yet, ever since 1970, the EU member states have succeeded to gradually intensify their foreign policy cooperation and increasingly act in unison towards the rest of the world. This PhD thesis seeks an explanation to this trend. It does so by initially painting a picture of when, in time, the volume and c

The drying of a porous material occurs in two different periods: the constant rate period and the falling rate period. During the constant rate period, the drying rate is determined by the external conditions regarding heat and mass transfer, and the drying rate is not influenced by the properties of the drying material. During the falling rate period, the material properties, such as the transpor

The aim of the study is to improve on the understanding of the implications for adolescents of being placed in foster care. The basis for the study is that the adolescents´ previous relationship with their parents has significance for the manner in which the adolescents will handle the separation from the parents and how they will relate to foster parents. 27 adolescents aged 13-16 years were exam

The need, for health educational reasons, of obtaining a more adequate understanding of how people think and act in connection with questions of dental health and professional dental care has been emphasized. The present study examines the attitudes and conceptions of adult individuals regarding their own dental health, as well as measures they take to further it. The aim is to elucidate factors t

This thesis is about parameter estimation and control of time-varying stochastic systems. It can be divided into two parts. The first part deals with an estimation algorithm commonly used when estimating parameters in time-varying stochastic systems, the Recursive Least Squares (RLS) algorithm with forgetting factor. The exact statistical properties for the RLS-estimator with forgetting factor ar
