  1. 1. Navigating Sustainability Transformations: Backcasting, transdisciplinarity and social learning

    Författare :Johan Holmén; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; backcasting; transformations; systems change; social learning; Education for Sustainable Development ESD ; Sustainability; transitions; reflexive governance; transdisciplinarity;

    Sammanfattning : Complex and persistent sustainability challenges necessitate transformations into futures that are fundamentally different to what was before. Such change processes cannot be planned in traditional ways; they require reflexive modes of governing where we collectively learn how to navigate uncharted terrain while exploring it. LÄS MER

  3. 2. Continuous Finding Problems and Implementing Solutions in Health Care-Associated Infections : The Role of Infection Preventionists

    Författare :Luís Fernando Irgang dos Santos; Magnus Holmén; Gerson Tontini; Fábio Gama; James Barlow; Högskolan i Halmstad; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health Care-Associated Infections; Infection Prevention and Control; Infection Preventionists; Problem-Finding and Problem-Solving Perspective; Implementation of Changes;

    Sammanfattning : This licentiate thesis aims to understand how infection preventionists (IPs) continuously find problems and implement solutions related to health care-associated infections (HAIs) in hospital settings.HAIs are infections acquired by patients during the process of care and are among the main causes of deaths worldwide.

  4. 3. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts

    Författare :Robert Andersson; Magali Boutonnet; Sven Järås; Anders Holmen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conversion; higher alcohols; mixed alcohols; MoS2; syngas; Chemical Engineering; Kemiteknik;

    Sammanfattning : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. LÄS MER

  5. 4. Improved energy efficiency in mill scale production of mechanical pulp by increased wood softening and refining intensity

    Författare :Erik Nelsson; Per Engstrand; Birgitta A. Engberg; Rodger Beatson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis focuses on the electric energy efficiency of single stage double disc refining for production of printing grade mechanical pulp from Norway spruce wood chips. The thesis is based on the hypothesis, that more energy efficiency refining can be attained by balanced increases of wood softening and refining intensity. LÄS MER

  7. 5. Quality Control of a Newsprint TMP Refining Process based on Refining Zone Temperature Measurements

    Författare :David Sikter; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature profile; quality control; usability; economy; TMP refining;

    Sammanfattning : The ultimate goal of this study was to examine the possibility of using temperature measurements for control purposes in a TMP refining process. The study was carried out in a commercial refiner line at Holmen Paper’s Hallsta Mill, were the primary stage refiner was equipped with temperature sensors. LÄS MER
