  1. 1. Closed-loop control and identification of resistive shell magnetohydrodynamics for the reversed-field pinch

    Författare :Erik Olofsson; Per Brunsell; Wolfgang Suttrop; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plasma physics with fusion; Plasmafysik med fusion; Automatic control; Reglerteknik;

    Sammanfattning : It is demonstrated that control software updates for the magnetic confinement fusion experiment EXTRAP T2R can enable novel studies of plasma physics. Specifically, it is shown that the boundary radial magnetic field in T2R can be maintained at finite levels by feedback. LÄS MER

  3. 2. Particulate Emissions Associated with Diesel Engine Oil Consumption

    Författare :Petter Tornehed; Ulf Olofsson; Gordon E. Andrews; KTH; []
    Nyckelord :Lubrication oil; Particulate emission; Particulate matter PM ; Oil consumption; Diesel engine; Mechanical engineering; Maskinteknik;

    Sammanfattning : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. LÄS MER

  5. 4. Cardiovaskular risk factors and complications in type 1 and type 2 diabetes

    Författare :Katarina Eeg-Olofsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes; Cardiovascular diseases; Epidemiology;

    Sammanfattning : Patients with diabetes have increased risk of cardiovascular disease (CVD) and mortality compared to the general population. The aim of this work was to describe the clinical characteristics and risk factors in patients with type 1 diabetes, and also to investigate the association between glycaemic control and CVD in type 1 and type 2 diabetes, and to analyse the association between BMI, overweight and obesity, and CVD in type 2 diabetes.

  7. 5. Human adenoviruses : new bioassays for antiviral screening and CD46 interaction

    Författare :Emma Andersson; Göran Wadell; Sigvard Olofsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; CD46; hemagglutination; antiviral; small molecule; screening; Virology; Virologi;

    Sammanfattning : Adenoviruses are common pathogens all over the world. The majority of the population has at some point been infected with an adenovirus. Although severe disease can occur in otherwise healthy individuals an adenovirus infection is most commonly self limited in these cases. LÄS MER
