  1. 16. Effect of selective estrogen receptor modulators (SERMs) on growth plate cartilage

    Författare :Elham Karimian; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : More than 300 years ago Dr. Stephen Hales drilled holes in the shaft of chicken bones and noted that as the animal grew, the distance between these holes remained constant. This led him to conclude that longitudinal bone growth occurs at the end of the long bones, rather than in the middle. LÄS MER

  2. 17. Regulation of growth plate and articular chondrocyte differentiation : implications for longitudinal bone growth and articular cartilage formation

    Författare :Michael Chau; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Overall height and body proportions in humans are determined primarily by bone growth. Linear bone growth occurs at the growth plate, a thin layer of cartilage at the ends of long bones between the epiphysis and metaphysis. LÄS MER

  3. 18. Multiscale Modelling of Proximal Femur Growth : Importance of Geometry and Influence of Load

    Författare :Priti Yadav; Elena Gutierrez Farewik; Marco Viceconti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone tissue modeling; deformity; biomechanics; osteogenic index; poroelastic material; octahedral shear stress; hydrostatic stress; fluid velocity; octahedral shear strain; MRI; walking; jumping; sedentation; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Longitudinal growth of long bone occurs at growth plates by a process called endochondral ossification. Endochondral ossification is affected by both biological and mechanical factors. LÄS MER

  4. 19. Study of generation, growth and breakdown of streamwise streaks in a Blasius boundary layer

    Författare :Luca Brandt; KTH; []
    Nyckelord :Fluid mechanics; laminar-turbulent transition; boundary layer flow; transient growth; streamwise streaks; lift-up effect; receptivity; free-stream turbulence; streak instability; secondary instability; Direct Numerical Simulation.;

    Sammanfattning : Transition from laminar to turbulent flow has beentraditionally studied in terms of exponentially growingeigensolutions to the linearized disturbance equations.However, experimental findings show that transition may occuralso for parameters combinations such that these eigensolutionsare damped.

  5. 20. Growth and Characterization of ZnO Nanocrystals

    Författare :Leif KE Ericsson; Kjell O Magnusson; Lars SO Johansson; Hanmin M Zhang; Omer Nour; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ZnO; Nanocrystals; Surface physics; XPS; SEM; AES; AFM; STM; Physics; Fysik;

    Sammanfattning : The understanding of surfaces of materials is of crucial importance to all of us. Considering nanocrystals (NCs), that have a large surface to bulk ratio, the surfaces become even more important. Therefore, it is important to understand the fundamental surface properties in order to use NCs efficiently in applications. LÄS MER
