Through the identification of a series of inscriptions, mainly datable to the Hellenistic era, a link between Aphrodite and the civic life and administration of the Greek poleis has come to light. The inscriptions in question are dedications to Aphrodite through which magistrates of various cities and varying status express their devotion to the goddess. In certain dedications, the goddess is even
This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. In the wetting experiments, water, alcohols, aqueous surfactant solutions and commercial ink-jet inks were used as test liquids, and a number of substrates, including silicate
In order to understand the formation and evolution of the Galaxy it is imperative to know when different components formed. This means at the most basic level that we need to know the ages of stars. The present work demonstrates the many problems inherent in determining the ages of stars through comparison with stellar evolutionary models. Furthermore, solutions to some of these problems are prese
A pulsed electric field (PEF) is a newly emerged non-thermal food processing technology which has characteristic effects on the cell membrane. PEF processing involves subjecting food to short, repeated pulses of a high electric field between an anode and a cathode. The main result of this process is the disruption of the cell membrane leading to the formation of either temporary or permanent pores
This study delves into the relationship between fiction and politics, aesthetic and ethical messages conveyed by the fictions of Brand (Fire), the journal of the Young Socialist Association, founded as the Social Democratic Labour Party’s first youth association. The literary and aesthetic arena allowed many different kinds of ideas and thoughts to flourish, making Brand an important cultural pape
This thesis consists of two parts, the first dealing with the design of iron-powder synchronous machines, and the second with the analysis and prediction of the acoustic noise in electrical machines. In Part I, a 1.6 kW electrically magnetized claw-pole machine with magnetically conducting end-plates has been analyzed and a prototype tested. The machine is built from soft magnetic composite mater
Fine-grained soils are often regarded as problematic soils in earthworks because of their water- and frost sensitivity. Only limited amounts of fine-grained tills are used as earthwork material today. The main objective of this thesis is to improve the knowledge of how to use and also treat a fine-grained till, so that a greater amount can be utilised as earthwork material. To achieve an increasin
This study examines safety and fear of crime in Åboland, a predominantly rural area in southwestern Finland. It also examines crime and criminals in the area, as well as the distinctive social control that characterises Åboland's eight municipalities. The study continues two strands of research, the first about criminality and fear of crime in societies that are considered safe by their inhabitant
The amino acid glutamate is today regarded as the main fast excitatory neurotransmitter in the central nervous system and a large body of evidence support that glutamate serves as a neurotransmitter in primary afferent terminals in the spinal cord. Previous evidence also suggests that the closely related amino acid aspartate may serve a similar role in some primary afferent terminals. However, the
In an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis. Three types of exanthema was described, scarlatiniform, urticarial and e
The molecular process under which message in DNA is relayed onto RNA is called transcription, and it accomplished through involvement of so-called transcription factors. Zinc finger proteins are one of the most abundant classes of regulatory proteins in eukaryotic cells where they play central roles in a variety of cellular activities. A classical zinc finger is a small protein motif with a simple
The work in this thesis has been focused on chondrocyte integrins and their interaction with the matrix proteins chondroadherin (CHAD) and collagen type II (CII). Affinity purification of CHAD-binding proteins from chondrocyte lysate, followed by immunoprecipitation of EDTA-eluted material identified alpha2beta1 as a CHAD-binding integrin. Interaction between alpha2beta1 and CHAD was found to prev
This thesis introduces and summarizes four papers dealing with computer simulations of astrophysical processes involving binaries. The first part gives the rational and theoretical background to these papers. In paper I and II a statistical approach to studying eclipsing binaries is described. By using population synthesis models for binaries the probabilities for eclipses are calculated for diff
This thesis consists of six articles on three different subjects in the area of complex analysis, operator theory and harmonic analysis. Part I - "The Shift Operator on Spaces of Vector-valued Analytic Functions" consists of three closely connected articles that investigate certain operators in the Cowen-Douglas class with spectrum D - the unit disc, or equivalently, the shift operator M_z
Both presence and extent of myocardial infarction are important prognostic factors for mortality and quality of life in patients with ischemic heart disease. Thus, it is of great clinical importance to be able to diagnose and characterize myocardial infarction. One way to diagnose myocardial infarction is by using the 12-lead electrocardiogram(ECG). For estimation of infarct size and location from
This thesis is about high energy heavy ion physics. Two major experiments, the WA98 at CERN and the PHENIX at Brookhaven National Laboratory, are described. Results from data analysis from both experiments are presented. The WA98 chapter presents particle identification methods and phi-meson measurements. A procedure for calculating efficiency maps for tracking chambers is discussed. The PHENIX ch
As Sustainable development, a widely used but poorly understood term, challenges traditional scientific values such as prediction and control, scientists have tried to manipulate the concept to promote their own particular agendas. Thus, it has suffered from misrepresentation which has prevented the concept from being fully implemented at a practical level. It is asserted that traditional fragmen
Background: Elective knee and hip arthroplasty are common surgical procedures. Improved anaesthetic and nutritional care has the potential of increasing patient satisfaction and reducing length of hospital stay (LOS). The overall aim of this thesis was to evaluate the effect of perioperative nutrition and different anaesthetic techniques on per- and postoperative outcome after elective total hip (
This thesis focuses on the consequences of the institutional transformations in South Africa during the 1990s with specific reference to the introduction of a mode of local governance based on the direct participation of private and civic actors in policymaking and implementation. The study also aims to contribute to theory. The approach is that public, private and civic associations are best unde
Proteoglycans consist of core proteins substituted with glycosaminoglycan chains. The galactosaminoglycans (GlcUA/IdoUA-GalNAc) and the glucosaminoglycans (GlcUA/IdoUA-GlcNAc) are both initiated on the same tetrasaccharide linkage region GlcUA-Gal-Gal-Xyl-protein. The proteoglycan decorin is bound to collagen fibrils in the extracellular matrix and is substituted with a single galactosaminoglycan
