  1. 1. The Significance of Things: Affective User-Artefact relations

    Författare :Viktor Hjort af Ornäs; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; User experience; User-centred design; Significant consequences; Significant use; Significant things; User-centred desig; Technology; Teknik; User Centred Product Design; Användarcentrerad produktdesign;

    Sammanfattning : Products help people act, but also thrill, excite, and elicit fear, joy and anger. Artefacts are a natural part of people’s everyday lives, sometimes associated with values, dreams and aspirations. While traditional user-centred approaches have focused on efficiency and effectiveness of use, injury prevention etc. LÄS MER

  3. 2. Fungal degradation patterns and toxicity of furfurylated wood

    Författare :Annica Pilgård; Chalmers University of Technology; []
    Nyckelord :Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

    Sammanfattning : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. LÄS MER

    Sammanfattning : The production of ethanol and other sustainable products including methane, limonene and pectin from citrus wastes (CWs) was studied in the present thesis. In the first part of the work, the CWs were hydrolyzed using enzymes – pectinase, cellulase and β-glucosidase – and the hydrolyzate was fermented using encapsulated yeasts in the presence of the inhibitor compound ‘limonene’.

  7. 5. User Centered Design Methods must also be User Centered: A Single Voice from the Field. A Study of User Centered Design in Practice

    Författare :Erik Styhr Petersen; Chalmers University of Technology; []
    Nyckelord :SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES; User Centered Design; Reflective Practice; Usability; Validity; Autoethnography;

    Sammanfattning : The present study concerns itself with the usability of the user centered design methodology, as this is defined by ISO 9241-210 (ISO9241-210, 2009) and other international standards: “[usability is the] extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use” (authors emphasis) (ISO9241-11, 1998; ISO9241-210, 2009, p. 3; ISO13407, 1999, p.
