  4. 3. Experimental study on turbulent boundary-layer flows with wall transpiration

    Författare :Marco Ferro; Jens Fransson; Bengt Fallenius; Joseph Klewicki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent boundary layer; boundary-layer suction; boundary-layer blowing; wall-bounded turbulent flows; self-sustained turbulence; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Wall transpiration, in the form of wall-normal suction or blowing through a permeable wall, is a relatively simple and effective technique to control the behaviour of a boundary layer. For its potential applications for laminar-turbulent transition and separation delay (suction) or for turbulent drag reduction and thermal protection (blowing), wall transpiration has over the past decades been the topic of a significant amount of studies.

  5. 4. Vetenskap på gränsen

    Författare :Tora Holmberg; Kaj Håkanson; Mark Elam; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; discourse analysis; sociology of science; cultural studies; Donna Haraway; boundary politics; figure; behavioural genetics; genomics; behaviour; human animal; twin; Sociologi; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : With behavioural genetic twin- and animal-studies as a point of departure, this thesis investigates how the polyphonic talk about genes creates certain conditions for how “human behaviour” can be constructed, how the politics of boundary fixing contributes to and undermines respectively, credible narratives about human behaviour and, in the extension, about what constitutes human-ness. Furthermore, sociology is used as a sounding board in order to investigate what behavioural genetic knowledge can promote in terms of sociological insights and vice versa. LÄS MER
