  1. 1. Determination of the thermal conductivity of the insulation in district heating mains : Field measurements

    Författare :Karin Margaretha Borgström; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating main; field measurements; thermal conductivity; measuring method; heat flow measurement; heat flux sensor; Material physics with surface physics; Materialfysik med ytfysik;

    Sammanfattning : This thesis concerns the development of a measurement method for determination in the field of the thermal conductivity of the insulation in buried district heating mains. The thermal conductivity of the insulation is calculated from the measured value of the radial heat flow through the heating main, the measured temperature difference across the insulation, and the dimensions of the heating main.

  3. 2. Accounting in the field of governance

    Författare :Sabina Du Rietz; Bino Catasús; Gustav Johed; Kalle Kraus; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; accounting; corporate; governance; field; investors; trade unions; accountability; technology; Business Administration; företagsekonomi;

    Sammanfattning : Corporate governance phenomena have traditionally been, and are still, studied foremost as relationships between principals and agents. Studies of how accounting plays out in corporate governance settings rather share the interest in hierarchical influence than challenge it. LÄS MER

  4. 3. Profession on the move : Changing conditions and gendered development in physiotherapy

    Författare :Ann Öhman; Umeå universitet; []
    Nyckelord :career; gender; division of labour; physiotherapy; health care; professional socialisation; professional development; gendered habitus; field; symbolic capital;

    Sammanfattning : Physiotherapy in Sweden has developed from a practical, hands-on, assistant job predominantly taught at college level to a university-based academic discipline emphasising evidence-based practice and research. Women are in majority although an increasing number of men have entered the profession. LÄS MER

  5. 4. A classifying algebra for CFT boundary conditions

    Författare :Carl Stigner; Jürgen Fuchs; Alexei Semikhatov; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary conditions; Conformal field theory; Factorization constraints; Modular tensor categories; TFT-construction; Mathematical physics; Matematisk fysik; Physics; Fysik;

    Sammanfattning : Conformal field theories (CFT) constitute an interesting class of twodimensionalquantum field theories, with applications in string theoryas well as condensed matter physics. The symmetries of a CFT can beencoded in the mathematical structure of a conformal vertex algebra. LÄS MER

  7. 5. Environmental actions on concrete exposed in marine and road environments and its response - Consequences for the initiation of chloride induced reinforcement corrosion

    Författare :Anders Lindvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; corrosion; de-icing salt; road conditions; marine conditions; service life predictions; reinforcement; chloride; concrete; moisture conditions; environmental actions;

    Sammanfattning : The object of the study presented here has been to describe, further explain and model the influence of the exposure conditions on reinforced concrete structures and the consequences on their expected service life. The focus has been on investigating and quantifying the exposure conditions for structures in marine and road conditions exposed to chloride ions. LÄS MER
