  1. 1. Diffusion in Bone Tissue

    University dissertation from Solid Mechanics, Faculty of Engineering, Lund University

    Author : Gustav Lindberg; [2013-11]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone growth; diffusion; stress enhanced; finite element method; steady-state; periosteal membrane; diffusion in bovine bone; diffusion experiment; Conductivity measurement; Fick’s law; Fourier series; Kalman filter; transient solution;

    Abstract : In order to prevent or modify the processes of bone degeneration the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. READ MORE

  2. 2. The role of microstructure for crack propagation in cortical bone

    University dissertation from Department of Biomedical Engineering, Lund university

    Author : Anna Gustafsson; [2019-11-11]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crack deflection; Interface; Mechanical testing; Micro-CT; Osteon; Porosity; XFEM;

    Abstract : Healthy cortical bone tissue is both tough and strong and has a unique ability to resist fracture. One reason is the hierarchical structure of the tissue where toughening mechanisms at all length scales act to slow down or stop a propagating crack. READ MORE

  3. 3. On the Growth of Bone through Stress Driven Diffusion and Bone Generation Processes

    University dissertation from Solid Mechanics, Faculty of Engineering, Lund University

    Author : Gustav Lindberg; [2018-10-30]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bone growth; Osteogenesis; Diffusion in bone; stress enhanced diffusion; Ginzburg-Landau; phase-field; diffusion experiment; Conductivity; Kalman filter; finite element method; Fourier series; Fick’s law; Osteology;

    Abstract : In order to prevent or modify bone degeneration due to rest or due to diseases such as osteopenia and osteoporosis, the modeling and remodeling of bone tissue must be better understood. In this thesis it is assumed that the primary condition leading to bone growth is a change of the chemical environment caused by transport of matter resulting from stress driven diffusion. READ MORE

  4. 4. Functional Ceramics in Biomedical Applications On the Use of Ceramics for Controlled Drug Release and Targeted Cell Stimulation

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Forsgren; Håkan Engqvist; Strømme Maria; Susanne Bredenberg; Pentti Tengvall; [2010]

    Abstract : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. READ MORE

  5. 5. Biomaterials as carriers for bone active molecules-An approach to create off-the-shelf bone substitutes

    University dissertation from Lund University: Faculty of Medicine

    Abstract : Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. READ MORE
