    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiotherapy; Sjukgymnastik;

    Sammanfattning : This monography thesis is based on five empirical studies of physical and psychosocial occupational strain in working life. The first three studies concern the working environment of crane couplers. LÄS MER

  3. 3. Ultrastructural Aspects of Pulp Fibers as Studied by Dynamic FT-IR Spectroscopy

    Detta är en avhandling från Stockholm : Fiber- och polymerteknologi

    Författare :Margaretha Åkerholm; KTH.; [2003]
    Nyckelord :cellulose; cooperation; crystallinity; dynamic test; glucomannan; hardwood; holocellulose; humidity; infrared spectroscopy; kraft pulp; lignin; mechanical pulp; orientation; polarised light; softwood; strain; sulphite pulp; viscoelasticity; xylan;

    Sammanfattning : Dynamic (or 2D) FT-IR spectroscopy in combination withpolarized IR irradiation has been used in this work to studywood polymer orientation and interactions on theultrastructural level in wood fibers in the native state aswell as the effects of different pulping processes. The woodpolymer interactions were studied under both dry and humidconditions. LÄS MER

  4. 4. Electronic Transport in Strained Materials

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Nyckelord :Physics; Conductivity; Strain; Transport; Boltzmann theory; Transition metal; Hydrogen loading; Electronic structure; Density functional theory; Bulk material; Multilayer; Fysik;

    Sammanfattning : In this thesis the conductivity of strained materials has been investigated using density functional theory and a semiclassical transport theory based on the Boltzmann equation.In transition metals trends are reproduced without adjustable parameters. LÄS MER

  5. 5. Quantitative Electron Microscopy Studies of Metal Nanoparticle Catalysts: Nanostructure, Support Interaction and Ageing Effects

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg
