    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Psoriatic Arthritis; genetics; inflammasomes; polymorphisms; biomarkers; disease expression; disease activity; cardiovascular diseases; mortality; epidemiology;

    Abstract : Psoriatic Arthritis (PsA) is a heterogonous inflammatory arthritis associated with psoriasis. The disease leads to inflammation of peripheral joints, axial skeleton and/or enthesites, and can result in severe destruction of affected joints. READ MORE

  4. 2. Fouling in biomass fired boilers

    Author : Jan Sandberg; Rebei Fdhila; Erik Dahlqvist; Alain Liné; Mälardalens högskola; []
    Keywords : Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : This thesis describes a detailed investigation into fouling in biomass fired boilers according to fuel mixture, combustion conditions, transportation of particles by the flue gas and the probability of particles impinging and sticking onto heat transfer tubes. The effects of fouling on overall boiler performance and the efficacy of soot blowing are also investigated. READ MORE

  5. 3. Fouling in biomass fired boilers

    Author : Jan Sandberg; Rebei Bel Fdhila; Erik Dahlqvist; Anders Nordin; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fouling; deposit; boiler; biomass; simulations; Thermal energy engineering; Termisk energiteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In order to reduce the discharge of the greenhouse gas CO2, the use of biomass is nowadays promoted as fuel in boilers. Compared to boilers fired with coal and oil the biomass-fired boilers have more complications related to both fouling and corrosion on the heat transfer surfaces. READ MORE
