  1. 21. Process Industry Energy Projects in a Climate Change Conscious Economy

    Författare :Anders Ådahl; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; process Integration; pulp mill; Nordic countries; energy market; climate policy; CO2; energy savings; biofuel;

    Sammanfattning : Most industrial process plants consume large amounts of energy (usually in the form of steam and electricity) to produce demanded goods, such as beer or paper. However, combustion of fossil fuels has negative external effects on the Earths climate. LÄS MER

  3. 22. Appropriation by Coloniality : TNCs, land, hegemony and resistance. The case of Botnia/UPM in Uruguay

    Författare :Adrián Groglopo; Simon Lindgren; Aina Tollefsen; Stellan Vinthagen; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Transnational corporations; foreign direct investments; foreignization of land; Latin America; pulp; hegemony; resistance; social movements; Sociology; sociologi;

    Sammanfattning : The overall aim of this thesis is to analyse the social consequences of a transnational corporation(TNC) from the global North investing capital in the global South, and the communal processes that evolve in response. The study highlights the TNC’s construction of leadership and domination in the areas in which it settles, as well as the forces of popular resistance to the TNC’s exploitation of the region’s natural resources and the resulting socio-environmental conditions.

  4. 23. Aspects on Strenght Delivery and Higher Utilisation of the Strength Potential of Kraft Pulp Fibres

    Författare :Elisabet Brännvall; Mikael Lindström; Herbert Sixta; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : Studies on strength delivery and related fields have so far concentrated on finding the locations in the mill where fibres are damaged and what the damages consist of. However, fibres will invariably encounter mechanical stresses along the fibreline and in this thesis a new concept is introduced; the vulnerability of fibres to mechanical treatment. LÄS MER

  5. 24. Simulations of Evaporation Plants in Kraft Pulp Mills: Including Lignin Extraction and Use of Excess Heat

    Författare :Marcus Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft pulp mill.; lignin extraction; heat integration; process integration; energy saving; excess heat; simulation; Energy-efficient evaporation; modelling;

    Sammanfattning : In this thesis, evaporation plants at kraft pulp mills are simulated with the purpose of making them more energy efficient. The work is important since energy saving is assumed to be one of the major solutions for handling the world's energy demand in the future. LÄS MER

  7. 25. Exhaled Nitric Oxide in epidemiological and experimental studies

    Författare :Anna-Carin Olin; Göteborgs universitet; []
    Nyckelord :Nitric oxide; exhaled air; nasal nitric oxide; ozone; pulp-mill; gassings; nitrate; ; atopy; sensitization; asthma; rhinitis; bronchiolitis;

    Sammanfattning : The overall purpose with this thesis has been to contribute to the assessment of theutility of exhaled nitric oxide (eNO) in epidemiological studies. The specific aims have been toinvestigate whether eNO increases after occupational exposure to high peaks of ozone, or afterexperimental exposure to ozone in ambient concentrations. LÄS MER
