  1. 6. Hälsoarbetets möte med skolan i teori och praktik

    Författare :Lena Nilsson; Christina Gustafsson; Bengt Lindström; Sven Hartman; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; health promotion; health education; health promoting schools; school development; salutogenic model; empowerment; student participation; democracy; on; democracy; writing; dialogue; pedagogik; Education; Pedagogik; Education; Pedagogik;

    Sammanfattning : The overall aim of the thesis is to investigate whether, and if so how, schools can be developed in a way that foregrounds a greater awareness of their role in the promotion of health.This thesis is about how the school itself, that is to say everything that can be subsumed within the notion of education, can promote health.

  3. 7. Turbulent Swirl Flow Modeling for Combustor Applications

    Författare :Andrej V. Smirnov; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Numerical simulations of three-dimensional confined swirl flows in a combustion chamber geometry are carried out with improved turbulence and combustion models. In the first part of the work a comparative study of six turbulence models is done in application to swirl flow. LÄS MER

  4. 8. Experiments and simulations of lean methane combustion

    Författare :Jenny Lindberg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Computational fluid dynamics of methane combustion using chemical kinetics for description of the chemistry is studied. Linear least squares data fit to measured concentrations and temperatures is used to modify reaction rate parameters in the Arrhenius rate equation for combustion of methane. LÄS MER

  5. 9. On the Evolving Friction of Layered Materials and the Prospect of Their Image Reconstruction

    Författare :David Andersson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

    Sammanfattning : The scope of this licentiate thesis is twofold: 1. Investigate the frictional properties of systems with layered materials; 2. Employing image recognition algorithms to find the substrates in AFM experiments. LÄS MER

  7. 10. Modelling of cathode-plasma interaction in short high-intensity electric arc : Application to Gas Tungsten Arc Welding

    Författare :Alireza Javidi Shirvan; Isabelle Choquet; Håkan Nilsson; Armelle Vardelle; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Electric arc discharge; sheath; pre-sheath; Knudsen layer; doped refractory cathode; arc-cathode coupling; Gas Tungsten Arc simulation; OpenFOAM.; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : In arc welding the quality of the weld is strongly influenced by the thermal history of the workpiece which is itself governed by the electric arc heat source. The models for predicting weld properties thus need a good evaluation of the distribution of the heat input from thearc to the workpiece. LÄS MER
