  2. 1. Nonaxisymmetric experimental modal analysis and control of resistive wall MHD in RFPs : System identification and feedback control for the reversed-field pinch

    Author : K Erik J Olofsson; Per Brunsell; Marco Ariola; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic confinement fusion; Reversed-field pinch; System identification; Magnetohydrodynamics; Modal analysis; Automatic control; Resistive wall modes;

    Abstract : The reversed-field pinch (RFP) is a device for magnetic confinement of fusion plasmas. The main objective of fusion plasma research is to realise cost-effective thermonuclear fusion power plants. The RFP is highly unstable as can be explained by the theory of magnetohydrodynamics (MHD). READ MORE

  4. 2. Leg ulcer management in primary care with special reference to pinch grafting

    Author : Rut Öien; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rheumatology locomotion; Skelett; muskelsystem; reumatologi; General practice; medical training; Allmän medicinsk utövning; medicinsk utbildning; muscle system; Skeleton; diameter product; grid tracing; digital planimetry; ulcer size; pain relief; vasculitis; rheumatoid arthritis; cost analysis; healing rate; pinch grafting; aetiology; prevalence; Leg ulcer; primary care;

    Abstract : Wound management in primary and community care was investigated throughout a period of 12 years within a well-defined population in one county in Southern Sweden. The estimated prevalence of chronic leg and foot ulcers was 0.19% in 1998 and the mean prevalence was 0.20% during the years 1994-1998. READ MORE

  5. 3. Techno-economic evaluation of integrated lignocellulosic ethanol production

    Abstract : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. READ MORE
