Apoptosis is a kind of death that is best described as cellular suicide and it is important for normal tissue homeostasis. The process can be induced by a number of different stimuli and the dying cell goes through a defined pathway terminating in typical biochemical and morphological alterations of the cell. With my studies I wanted to investigate the role of the polyamines in the regulation of a
The nature of future climate change will depend on anthropogenic emissions of CO2, as well as climate- and CO2-mediated feedbacks through carbon (C) cycling in both terrestrial ecosystems and oceans. Terrestrial ecosystems remove presently about 25% of the anthropogenic CO2 fossil-fuel and land-use change emissions, but to attribute which mechanisms cause this uptake, and the key regions where it
The dynamic friction process and contact surface between tool and working material in a plastic forming process is hard to describe in mathematical form and hard to monitor and control in real time. High production speed and highly optimised forming operations result in great demands on the control equipment. Especially if the influence from variations due to the tool, work material and the fricti
The aim of this work was to achieve surface modification of two biomedical polyurethanes and one poly(urethane urea) through the addition of small amounts of amphiphilic copolymers in solution. The matrix polymers used were the poly(ether urethane)s Pellethane 2363-80AE (P80) and 2363-75D (P75) and a poly(ether urethane urea) similar to Biomer (PUUR). The amphiphilic additives consisted of segment
Positron emission tomography (PET) is a tracer technique used for quantitative in vivo studies of physiological and biochemical processes. Because of the use of positron-emitting radionuclides such as 11-C, 13-N, 15-O and 18-F, which are isotopes of the biologically ubiquitous elements, it is possible to label radiopharmaceuticals which trace biochemical processes precisely. In order to be able to
Forgetting can be highly functional when unwanted or irrelevant memory representations interfere with cognitive or motivational goals. Current theory assumes that forgetting can be brought about by the intentional or unintentional inhibition of interfering memory representations. In four studies, the present thesis investigated this claim by employing behavioral testing, and neuroimaging methods b
In the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a spon
This dissertation consists of a collection of previously published or otherwise presented essays dealing with the philosophical, sociological and aesthetic writings of Theodor W. Adorno (1903-1969). The title of the dissertation is intended to cover a common programmatic theme running through Adorno's writings. Chapter one, ?Adorno and the Frankfurt school?, deals with the biography of Adorno and
It has long been thought that aging is accompanied by an emotional flattening. Although a different view has started to emerge recently, studies investigating psychophysiological responses in reaction to affective stimuli so far have reported an age-related reduction of the affective response. One of the main goals of this thesis was to revisit this issue by examining subjective reports, phasic he
Goodpasture disease is a prototype autoimmune disease that is characterized by a rapidly progressive glomerulonephritis, with or without lung haemorrhage, associated with autoantibodies against the glomerular basement membrane. The major antigen has previously been shown to be the non-collagenous domain of the a3 chain of type IV collagen, one of the six known a chains of type IV collagen. On aver
The Late etruscan terracotta votive heads from Tessennano were found near a rural sanctuary about a hundred km to the North of Rome in 1956. Whereas the facial fronts are serially produced with moulds, the backs are handmade. By using not only the moulded and the handmade features but the raw material (clay and temper) as well, it has been possible to make suggestions as to how, when and where the
This thesis consists of five parts in which problems in two fields, medical and telecommunication, have been studied. In the first part, a prediction algorithm, the Prony method, for estimation of frequencies and damping factors of sinusiods is developed for a coloured noise disturbance. The method is applied to estimating a single Event-Related Potential, sERP, and the estimation principle is ev
What kind of public sphere is possible in the European Union? Against the backdrop of debates on the transformation of democracy beyond the nation-state, this study explores daily newspapers’ role in providing forums for transnational debate in the presumed absence of an overarching European collective identity. It uses empirical means to reconsider the question of the supposed co-constitutiveness
This thesis consists of four chapters where chapter 1 introduces the topics in the following chapters and discusses some related literature. Chapter 2 moves beyond the disability insurance with two types, able and disabled, in Parsons (1996). This is done in two ways: by introducing a third type, the partially disabled, and by allowing for a continuum of types. It is assumed throughout that the in
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 (
