  1. 1. Sågarnas sång : folkligt musicerande i sågverkssamhället Holmsund 1850-1980

    Författare :Alf Arvidsson; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ethnomusicology; working-class culture; workers music; soundscape; amateur music; popular music; dancing; concerts;

    Sammanfattning : The aim of this dissertation is to analyze the public music-making by locals in Holmsund 1850—1980, and to explain the great variety of musical forms in hope to thereby illuminate the importance of local music-making for the workers' musical taste, but also how workers' musical aesthetics were affected by a more general working-class culture. The variety of musical forms is explained according to John Blacking's distinction between change of musical system, and variation and innovation within a musical system. LÄS MER

  3. 2. Asthma and cancer among pulp and paper mill workers

    Författare :Eva Andersson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epidemiology; pulp and paper industry; irritant-induced asthma; gassings; cancer; sulfate mills; sulfite mills; maintenance work; brain tumors; glioma; lung cancer; asbestos;

    Sammanfattning : There were two main aims of this thesis. One was to study if repeated high exposures to irritant gases give rise to new-onset asthma, and the other was to study if exposure in pulp and paper mills were associated with cancer. LÄS MER

  4. 3. Fourier Transform Infrared Spectroscopy in Industrial Hygiene Applications : Assessment of Emissions from and Exposures in Wood Processing Industries

    Författare :Urban Svedberg; Christer Edling; Bo Galle; Hans-Erik Högberg; Nils Plato; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; FTIR; Exposure; Emission; Saw mills; Wood pellets; Tracer gas; Monoterpenes; Hexanal; Carbon monoxide; Open path FTIR; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Sammanfattning : This thesis evaluates the use of Fourier Transform Infrared Spectroscopy (FTIR) as an approach to the increasingly difficult air sampling challenges within the field of occupational and environmental hygiene. The application of FTIR is exemplified by the assessment of emissions from and exposures in the sawmill and pellet industries. LÄS MER

  5. 4. Optimization approaches to tactical planning problems in the forest industry

    Författare :Helene Gunnarsson; Ola Eriksson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : By using decision support tools based on operations research (OR) and optimization in the supply chain in the forest industry, the planning process can be improved and higher profitability can be obtained. The focus of this thesis is on modelling two real-life problems. LÄS MER

  7. 5. Supply chain optimization in the forest industry
