  2. 21. Methods for mechanical testing based on analysis of elastic waves in rods

    Author : Janne Carlsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : This thesis summarizes six papers on development and applications of a method to evaluate the normal force and particle velocity at any cross-section of a nonuniform rod from measurements of strain at two different cross-sections. In Paper A the method is developed. It is an extension of that developed by Lundberg and Henchoz for uniform rods. READ MORE

  4. 22. Interactions in MX-80 bentonite/water/electrolyte systems

    Author : Torbjörn Carlsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The main objective of this work was to study the influence of temperature, water ratio and electrolyte content on the molecular water mobility in water saturated MX-80 bentonite. T a minor extent the influence of pressure, time, and specific surface area on the molecular water mobility was studied. READ MORE

  5. 23. Ergonomics for the improvement of health and safety of female workers in industrially developing countries

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

    Abstract : 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.
