  2. 1. Islet xenotransplantation : An immunological study in the pig-to-mouse model

    Author : Birgitta Benda; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; xenotransplantation; porcine; islet; in vivo; knock-out mouse; immunohistochemistry; CsA; MDL 201; 449A; Ig; FcR; IL-6; perforin; granzyme B; macrophage; eosinophilic granulocyte; T cell; TCR; IFN- g; TNF- a; IL-2; Onkologi; Oncology; Onkologi; Clinical Immunology; klinisk immunologi;

    Abstract : Successful clinical xenotransplantation, i.e., transplantation between species, would eliminate the shortage of donor organs. In order to study the acute cellular rejection reaction following discordant xenogeneic transplantation, an experimental pig-to- mouse islet xenotransplantation model was established. READ MORE

  4. 2. Fundamental Control Performance Limitations for Interarea Oscillation Damping and Frequency Stability

    Author : Joakim Björk; Karl H. Johansson; Lennart Harnefors; Joe H. Chow; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system control; HVDC transmission control; interarea oscillations; power oscillation damping; small-signal stability; fundamental control limitations; frequency stability; hydro power; wind power; non-minimum phase; zero dynamics; eigenvalue analysis; Electrical Engineering; Elektro- och systemteknik;

    Abstract : With the transition towards renewable energy and the deregulation of the electricity markets, the power system is changing. Growing electricity demand and more intermittent power production increase the need for transfer capacity. Lower inertia levels due to a higher share of renewables increase the need for fast frequency reserves (FFR). READ MORE

  5. 3. Coordinated Frequency Control Between Interconnected AC/DC Systems

    Author : Danilo Obradovic; Mehrdad Ghandari; Robert Eriksson; Jonas Persson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power System Dynamics; Frequency Stability; Small Signal Stability; HVDC Supplementary Power Control; Electrical Engineering; Elektro- och systemteknik;

    Abstract : With ambitions of reducing the environmental pollution, power systems integrate larger shares of Renewable Energy Sources (RES) to phase out conventional thermal and nuclear generators. Since RES (such as wind and solar power) are connected to the grid through power electronics devices, they do not inherently contribute to system inertia. READ MORE

  6. 4. Coordinated Frequency Control Using DC Interconnections Between AC Systems : Utilizing Fast Frequency Support through HVDC Links and Evaluating the Newly Uncovered Dynamics in Low-Inertia Power Systems

    Author : Danilo Obradovic; Robert Eriksson; Mehrdad Ghandhari; Damian Flynn; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Transmission system operators are increasingly adopting renewable energy sources in response to the escalating need to reduce environmental pollution. However, renewable energy sources, like wind and solar power, connect to the grid through power electronics, offering no inherent inertia. READ MORE

  7. 5. Fc receptors and immunoglobulins in polyarthritis : A matter of function, supply and demand?

    Author : Peter Matt; Ulla Lindqvist; Sandra Kleinau; Alf Kastbom; Uppsala universitet; []
    Keywords : ;

    Abstract : Fc receptors (FcR) and immunoglobulins (Ig) play important roles in the defence against pathogens. However, altered interactions of these may promote chronic inflammation in rheumatic diseases. An excess of Igs forming immune complexes (IC) could lead to continuous FcR activation and spreading of autoimmune inflammation to other tissues. READ MORE
