  1. 1. Kulturen och arbetarrörelsen : Kulturpolitiska strävanden från August Palm till Tage Erlander

    Författare :Per Sundgren; Staffan Källström; Per-Olof Mattsson; Svante Beckman; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; cultural policy; labour movement; popular education; class-struggle education; Social Democracy; Communism; left socialism; popular culture; bourgeois culture; educational idealism; Såningsmannen; Oscar Olsson; Ture Nerman; History of science and ideas; Idé- o lärdomshistoria; idéhistoria; History of Ideas;

    Sammanfattning : This thesis comprises studies on a theme. The theme is cultural political ambitions in the Swedish labour movement from August Palm to Tage Erlander, from the first tentative steps of popular education at the end of the 19th century to the first cultural political programmes fifty years later.

  3. 2. Osteoarthritis of the Hip and Uncemented Total Hip Arthroplasty : Effects of Immediate Weight Bearing on Implant Stability, Bone Mineral Density, and Body Composition

    Författare :Olof Wolf; Hans Mallmin; Sune Larsson; Jan Milbrink; Per Mattsson; Per Adolphson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis of the hip; uncemented; total hip arthroplasty; stability; RSA; BMD; DXA; body composition; weight bearing; Orthopaedics; Ortopedi; Orthopaedics; Ortopedi;

    Sammanfattning : The initial recommendation for the postoperative regime after uncemented total hip arthroplasty (THA) was 6-12 weeks of partial weight bearing (PWB) to obtain a stable implant position during bone ingrowth. In recent years patients with uncemented THA have increasingly practiced full weight bearing (FWB) after surgery, which has largely been based on clinical experience rather than on scientific evidence.

  4. 3. Intracranial facial nerve lesion : experimental study on neural degeneration and its treatment

    Författare :Per Mattsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The aim of this thesis was to develop an experimental model that would generate extensive motor neuronal degeneration in adult rats, and furthermore to study mechanisms causing nerve cell death and effects of putative neuroprotective compounds. The facial nerve was chosen because it is well characterized and allows evaluation of functional recovery by analyzing vibrissae movements. LÄS MER

  5. 4. Pulse-modulated feedback in mathematical modeling and estimation of endocrine systems

    Författare :Per Mattsson; Alexander Medvedev; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : The research field of systems biology has gained a lot of interest during the last decades. Systems biology can be seen as the systematic study of complex interactions in biological systems, mainly by methods from dynamical systems theory. LÄS MER

  7. 5. Continuously Variable Split-Power Transmissions with Several Modes

    Författare :Per Mattsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; continuously variable transmission; variator; speed ratio range; ratio coverage; traction drive; mode shift; CVT; planetary gear; power split; IVT; infinitely variable transmission; epicyclic gear train; hydrostatic variator;

    Sammanfattning : A continuously variable transmission (CVT) of split-power design consists of a variator and an arrangement of planetary gears. A black box model describing such transmissions is presented. The model can be used for synthesis as well as loss-free analysis of split-power CVT concepts in general. LÄS MER
