  1. 16. Steel fibrous cement based composites: material and mechanical properties : behavior in the anchorage zones of prestressed bridges

    Författare :Lutfi Ay; KTH; []
    Nyckelord :process improvement of bridges; prestressed concrete; high performance concrete;

    Sammanfattning : This PhD thesis is divided into two parts. Part one dealswith the development of the material and the mechanicalproperties of Steel Fibrous Cement Based Composites (SFCBC) forimproving bridge design and construction. It familiarizes thehydration mechanisms of the high performance concrete with thehelp of Powers´ and Jensen´s models. LÄS MER

  3. 17. Strengthening reinforced concrete structures with FRP composites

    Författare :Jincheng Yang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GFRP; finite element analysis.; corrosion; interfacial stress; externally bonded reinforcement; self-anchorage; CFRP; debonding; concrete structures; Fibre reinforced polymer; prestressing level;

    Sammanfattning : Civil infrastructures made of reinforced concrete (RC) play an important role in the economic activities and services of society. However, signs of deterioration and functional deficiency are commonly found in existing RC structures. Thus, there is a great demand for upgrading the capacity and performance of existing concrete structures. LÄS MER

  5. 19. Cell cycle control in G1 : restriction points for growth factors and anchorage dependence

    Författare :Peter Zickert; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :cell cycle; cyclin E; growth control; growth factor; restriction point; ECM; anchorage;

    Sammanfattning : Background: The eukaryotic cell cycle consists of four well-defined phases. During the S phase DNA is replicated and during the M phase the chromosomes are segregated to daughter cells. The time gap between completion of M phase and entry into S phase is called G1. The time gap between S phase and mitosis is called G2. LÄS MER

  7. 20. Being physically active : a bodily anchorage on the journey for recovery in mental ill-health

    Författare :Oona Bettina Lassenius; Mälardalens högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :caregivers; Care Sciences;

    Sammanfattning : Suffering from mental ill-health does not merely involve mental distress; it also often comprises deteriorated physical health. The physical consequences can be of a severe nature and may lead to premature death. LÄS MER
