  1. 21. Molecular and functional studies on human embryo implantation : targets for infertility and fertility regulation

    Författare :Nageswara Rao Boggavarapu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: An estimated one in four couples globally suffers from infertility or fertility related issues and rate of global infertility is about 10-15%. Despite the best optimization of assisted reproductive technique the pregnancy rate is not more than 30%. LÄS MER

  3. 22. Overcoming inertia to sustainable stormwater management practice

    Författare :Annicka Cettner; Sarah Bell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : In Sweden, there is a growing receptivity for change to more sustainable stormwater practices using green infrastructure approaches. Unlike piped drainage systems they can have multiple benefits in use including flood control, pollutant removal and can add to the quality of urban space supporting green infrastructure through irrigation and providing cooling and an additional water source for supply.

  4. 23. Oblique waves in boundary layer transition

    Författare :Stellan Berlin; KTH; []
    Nyckelord :;

    Sammanfattning : Traditional research on laminar-turbulent transition has focused on scenarios that are caused by the exponential growth of eigensolutions to the linearized disturbance equations, e.g. two-dimensional Tollmien-Schlichting waves. LÄS MER

  5. 24. An experimental investigation of disturbance growth in boundary layer flows

    Författare :Thomas Kurian; P. Henrik Alfredsson; Jens H. M. Fransson; Edward B. White; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : This thesis deals with the early stages of transition to turbulence in two different baseflows, namely the Falkner-Skan-Cooke boundary layer (FSC) and the asymptotic suction boundary layer (ASBL). Grid-generated turbulence is studied in order to characterise the isotropy levels, free-stream turbulence levels and characteristic length scales that will be present in the receptivity study.

  7. 25. Male and female selective mechanisms, reproductive success and gene flow

    Författare :Samuel Kiboi; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; Cucumis sativus.; genetic marker; gene flow; reproduction; embryo abortion; resistance; maternal selection; sexual selection; pollen competition; selection;

    Sammanfattning : In this thesis, I have studied male and female selective mechanisms that can affect plant reproductive success and gene flow. I have focussed on sexually selected traits, mainly pollen competition and maternal sorting mechanisms, for example through non-random ovule abortion. LÄS MER
