  1. 31. Ergonomics for the improvement of health and safety of female workers in industrially developing countries

    Författare :Pranee Chavalitsakulchai; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

    Sammanfattning : The thesis presents the results of an ergonomics survey which contains eleven studies in five different industries of Thailand and four different industries of Japan (Papers A to K). The aims of the studies were; (i) to identify priority problems of female workers in different industries from ergonomic points of view; (ii) to analyze and investigate these problems; (iii) to examine the ergonomics intervention practices at work places; and iv) to develop a practical method for appropriate ergonomics interventions at work for improving health and safety of female workers, particularly in industrially developing countries.

  7. 35. Boundary lubrication in screw-nut transmissions

    Författare :Lars O. Ekerfors; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : This report deals with the function of screw-nut transmissions (powerscrews). Two aspects of this function have been investigated. Owing to different running parameters, primarily sliding speed and average pressure between the sliding surfaces of the thread, the coefficient of friction and the efficiency will vary within wide limits.
