  1. 11. Essays on Macro-Financial Linkages

    Författare :Rafael Barros de Rezende; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This doctoral thesis is a collection of four papers on the analysis of the term structure of interest rates with a focus at the intersection of macroeconomics and finance. "Risk in Macroeconomic Fundamentals and Bond Return Predictability" documents that factors related to risks underlying the macroeconomy such as expectations, uncertainty and downside (upside) macroeconomic risks are able to explain variation in bond risk premia.

  4. 13. Sub-micron Structures in Laser Ablated YBa2Cu3O7-x Thin Films

    Författare :Peter Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis treats the epitaxial growth of high-Tc superconductors and other perovskite oxides as well as the patterning of these into sub-micron structures for superconducting electronic devices. A computer controlled laser ablation system, based on a KrF excimer laser (248 nm) to induce ablation, was developed to allow complex thin film growth processes. LÄS MER

  5. 14. Electroosmosis Based Treatment Approach for Cerebral Edema

    Författare :Teng Wang; Xiaogai Li; Svein Kleiven; Tiit Illimar Mathiesen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cerebral edema; electroosmosis based treatment; finite element head model; electroosmotic flow; Technology and Health; Teknik och hälsa;

    Sammanfattning : Cerebral edema characterized as an abnormal accumulation of excess fluid in the intracellular or extracellular spaces has not been treated effectively despite aggressive treatments. As a result, cerebral edema often leads to intracranial pressure (ICP) elevation with potentially severe consequences unless treated effectively. LÄS MER

  7. 15. System Aspects of Black Liquor Gasification – Consequences for both Industry and Society

    Författare :Håkan Eriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; Black liquor gasification; Biomass; Combined Cycle; Eco cyclic pulp mill; CHP; Electricity production; Recovery boiler; Gas turbine;

    Sammanfattning : The pulp and paper industry consumes large quantities of biofuels (mainly bark and black liquor) to satisfy process requirements. Biomass is however a limited resource, and biofuel usage should therefore be as effective as possible. LÄS MER
