Popular Abstract in Swedish Denna avhandling presenterar nya metoder för att analysera bilder på hjärtat för att utesluta eller bekräfta kranskärlssjukdom. Hjärtat har en livsviktig uppgift, att pumpa runt blodet för att förse alla kroppens organ med energi och syre. Vid förträngningar i kärlen som försörjer hjärtmuskeln med blod (kranskärlen) uppkommer ett tillstånd som kallas ischemisk hjärtsjukIn this thesis, methods for automated analysis of myocardial perfusion single photon emission computer tomography (myocardial perfusion SPECT, MPS) images have been successfully developed and evaluated. MPS images show the perfusion of the myocardium and are used for diagnosing patients with suspected ischemic heart disease. The disease is characterized by reduced perfusion to a region of the myoc

In this thesis a simulation model is presented that enables a comparison of different hybrid topologies, with respect to fuel consumption, emissions and performance. The obtained results stress the properties of the different topologies and form a foundation for the choice of hybrid topology. The simulation models included in this thesis are the result of collaboration with Petter Strandh at the D

Dialogue or governance? The relationship between the state and the voluntary organizations, with particular focus on Överenskommelsen (the compact) and the Church of Sweden Government-voluntary sector compacts have emerged in the recent years, as a nonprofit policy practice in many industrialized countries. The compact – in Sweden signed by the government in 2008 – is by some researchers regarded

This volume is a collection of some of the most important philosophical papers by Peter Gärdenfors. Spanning a period of more than 20 years of his research, they cover a wide ground of topics, from early works on decision theory, belief revision and nonmonotonic logic to more recent work on conceptual spaces, inductive reasoning, semantics and the evolutions of thinking. Many of the papers have on

This memo reports on factors that drive and inhibit the digitalization of security systems. The reported factors are as follows: Technology-push factors • Need to lower costs on the end-user side, i.e. replacing labour with technology • Perceived convenience and ease-of-use of digital systems • Digital products can be connected to the current enterprise network; enabling an expanding set of secur

Popular Abstract in Swedish Proteiner är livsnödvändiga och finns i alla celler. De flesta proteinerna katalysear kemiska reaktioner och kallas då enzymer. Enzymer och proteiner (äggviteämnen) är uppbyggda av aminosyror ihopkopplade till kedjor som kan vara olika långa. Det finns 20 stycken olika aminosyror. Man kan göra en liknelse med ett pärlhalsband tillverkat av 20 olika pärlor, varje pärla mFerrochelatase catalyses the terminal step in heme biosynthesis by inserting a ferrous ion into protoporphyrin IX. The reaction mechanism has in this thesis been studied by mainly crystallographic methods. The structure of ferrochelatase from Bacillus subtilis co-crystallized with N-methyl mesoporphyrin allowed for the first time a characterization of the active site of the enzyme. The structure

Financial theory, resource-based theory and deal flow generation are used to explain synd ication practices among venture capitalists in Belgium, France, The Netherlands, Sweden and the UK. Similar motives drive syndication in the five countries: the desire to share risk and increase portfolio diversification is more important than the desire to access additional intangible resources or deal flow.

Three methods are presented to calculate the load distribution in a chain drive containing two sprockets and one chain. The rollers, which are in contact with the sprockets, can move along the tooth flanks and their positions are given by force equilibrium. Since the positions of the rollers, and thereby also the load distribution, depend on the two connecting spans, it has been necessary to inclu
