Three-terminal ballistic junctions: New building blocks for functional devices in nanoelectronics

Present digital logic gates are primarily built from field effect transistors (FETs) such as complementary metal oxide semiconductors with the gate length in the deep sub-μm regime. As device feature sizes approach the nanometer regime, fundamental physical constraints and increasingly prohibitive economic costs will make further miniaturization in electronic circuits difficult, and this has motiv

Comparison of vulnerability and reliability analysis of technical infrastructures

The society depends on reliable and robust services provided by technical infrastructures for its function. The impact of large-scale outages due to the inherent vulnerabilities of technical infrastructures has been demonstrated, for example, by the power outage in the U.S. in 2003 and the power outages in Sweden due to the storms Gudrun in January 2005 and Per in January 2007. Two of the main app

Use of calcium channel blockers as antihypertensives in relation to mortality and cancer incidence: a population-based observational study

Abstract Purpose Treatment with blood pressure lowering drugs may reduce morbidity and mortality. However, the efficacy and effectiveness may differ between antihypertensive agents. The current investigation aimed to compare mortality and cancer incidence in hypertensive patients treated with calcium channel blockers (CCB) or with other antihypertensive drugs (AHD). Methods All patients in two o

Mellan vanor och faror : ett kulturanalytiskt perspektiv på äldre människors bruk av läkemedel

Denna studie avser att undersöka den mening som mediciner skapar, och hur de påverkar människors vardagliga erfarenheter och identitetsskapande. Medicineringens relation till kroppsliga tecken och symptom påvisar den spänning som finns i synen på läkemedlet; mediciner som något farligt och riskfyllt men samtidigt med förmåga att förebygga och bota. Mediciners farlighet tycks delvis kunna motverkasThis study aims to explore the meaning that is created when using medicines, and how medicines affect older people’s experiences of everyday life and their identity. The connection between medicines and the body demonstrates the tension that the medications contain; something dangerous and unsafe but with the power to cure and prevent illness. The risks of medications seem to be counteracted throu

On overload control of Intelligent Peripherals in Intelligent Networks

The intelligent peripheral (IP) is one of the key central resources in the intelligent network concept, allowing user to network interaction for services such as credit card calling. User access to IPs is controlled by service control points (SCPs) and is typically gained via voice trunk groups from service switching points (SSPs), with many services sharing common SSP-IP trunk group facilities. T

Analysis of an extended ionization equilibrium in the post-flame gases for spark ignited combustion

Constant volume combustion is studied, using a zero-dimensional model, which is a wide-ranging chemical kinetic simulation that allows a closed system of gases to be described on the basis of a set of initial conditions. The model provides an engine- or reactor-like environment in which the engine simulations allow for a variable system volume and heat transfer both to and from the system. The com

Enzymes and mechanisms for violaxanthin-zeaxanthin conversion

The xanthophyll cycle is of great importance in relation to light stress. Particularly, interest has been focused on the possible photoprotective role of zeaxanthin. In higher plants under light stress, zeaxanthin is formed from violaxanthin in a reaction catalyzed by violaxanthin de-epoxidase (VDE). The reverse reaction is catalyzed by zeaxanthin epoxidase (ZE) under low light or in darkness. VDE

Dynamic Communication: an Analytic and Constructive Study on the Problem of Religious Communication, based on Martin Buber's Philosophy of Dialogue

Popular Abstract in Swedish I avhandlingen "Dynamisk dialog: en analytisk och konstruktiv studie av den religiösa kommunikationens problem på grundval av Martin Bubers dialogfilosofi" studerar jag olika aspekter av Bubers modell för hur en människa meningsfullt kan kommunicera sin religiösa upplevelse till och med en annan människa. Min metod har både en begreppsanalytisk och en fenomenologisk sidIn the present work, I study various aspects of Martin Buber's model of how a human being can communicate, in a meaningful way, his or her religious experiences to and with another human being. My method has aspects of both conceptual analysis and phenomenologial description. I focus on the individual partners, their mutual relationships and the religious message. Buber's model is based on the con
