Taking Fëdor Dostoevskij’s and Ljudmila Petrusevskaja’s writings as its starting point, this dissertation explores two different forms of disintegration of worth. In both cases, a world is described where human beings have lost contact with a unique centre of worth – a position in space linked to an irrevocable course of events in time. In Dostoevskij, this disintegration takes place on the level

This paper reports on multiconfiguration Dirac-Hartree-Fock calculations for intercombination lines in highly charged silicon-like ions. Results for wavelengths, fine structure, transition rates, branching ratios and lifetimes are reported and compared with other theories and experiments. A review of the experimental situation is presented, and deviations from expected smooth trends along the sequ

n this study, we show that costimulation required for mucosal IgA responses is strikingly different from that needed for systemic responses, including serum IgA. Following oral immunization with cholera toxin (CT) adjuvant we found that whereas CTLA4-H{gamma}1 transgenic mice largely failed to respond, CD28-/- mice developed near normal gut mucosal IgA responses but poor serum Ab responses. The lo

Several bacterial species express surface proteins with affinity for the constant region (Fc) of immunoglobulin (Ig) G. The biological consequences of the interaction with IgG are poorly understood but it has been demonstrated that genes encoding different IgG Fc-binding proteins have undergone convergent evolution, suggesting that these surface molecules are connected with essential microbial fun

A reinvestigation of the phase diagrams relative to some conjugated and non-conjugated bile salts in water has demonstrated the formation of lyotropic liquid crystalline phases, in contradiction with generally accepted statements. The phase behaviour is complex and the phase diagrams are unusual, compared to most surfactants and lipids. In particular, coexistence of liquid crystalline phases with

ECGs were recorded from three electrodes attached at the corners of an equilateral triangle positioned around the location of electrode V1. The atrial signal between QRST complexes was subjected to correlation function analysis to reveal differences in activation times between the electrode sites. The time differences found were used to calculate the direction of activation across the body surface

”Jag hoppas att jag får ha hälsan”, är ett uttryck som idag känns passé. Hälsa är inte längre något man ”har”, eller ens ”får”. Idag är hälsa något man ”gör”. Det är individens ansvar att ”göra” sin hälsa genom att äta rätt, motionera väl, hålla sig uppdaterad om vetenskapliga rön och nya behandlingsmetoder och inte minst – tro på sig själv. Hälsa är – åtminstone i den offentliga diskursen – beroe

The inverse spectral problem for the Laplace operator on a finite metric graph is investigated. It is shown that this problem has a unique solution for graphs with rationally independent edges and without vertices having valence 2. To prove the result, a trace formula connecting the spectrum of the Laplace operator with the set of periodic orbits for the metric graph is established.

Popular Abstract in Swedish I »operatörens blick« beskrivs ett projekt där möjligheter för IT-stöd i erfarenhetsöverföring undersökts inom ett område där konfrontationen mellan datorisering och yrkeskunnande är särskilt tydlig - operatörsarbete i processindustrin. Driftsstörningar av olika omfattning är ett kontinuerligt inslag i operatörsarbetet och snabba förändringar i risknivå är en central deStudies in process control automation show that manual control skills are important in handling situations where the automatic control system fails. The fact that these skills are particularly difficult to maintain and develop in automated production environments is usually described as one of the ironies of automation. This work explores new roles for computer support in developing and maintainin

Refillable polyester bottles, for example polyethylene terephthalate (PET) bottles, are known to interact with chemicals. Aroma compounds from a product can be absorbed by the bottle material, remain after washing and remigrate when the bottle is reused, resulting in off-flavour of the new product. A certified reference material has recently been approved with which the chemical and sensory inertn

This paper considers the problem of stability of linear feedback systems with time-varying but bounded delays. Simple but powerful criteria of stability, as well as a simple performance bound, are presented for both continuous-time and discrete-time systems. Using these criteria, stability can be checked in a closed loop Bode plot. This makes it easy to design the system for robustness.

The first aim of this doctoral work has been to develop a new generation of computer programs for transient and steady-state heat conduction in two and three dimensions. A large range of heat transfer problems within the field of buildings physics can be analyzed using these tools. There are, however, many things to keep in mind when modelling a problem, such as how to choose the numerical mesh,

A thorough kinetic investigation of the ammoxidation of toluene over a V2O5 catalyst was carried out. Pressures of reactants were varied and rates for formation of benzonitrile and benzaldehyde were determined. Kinetic expressions completely describing experimental data were derived. A mechanisms is proposed on basis of both rate equations and other types of information published in the literature

We investigated if low level laser therapy (LLLT) of the joint capsule can reduce pain in chronic joint disorders. A literature search identified 88 randomised controlled trials, of which 20 trials included patients with chronic joint disorders. Six trials were excluded for not irradiating the joint capsule. Three trials used doses lower than a dose range nominated a priori for reducing inflammati
