  2. Strain (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Strain_(mechanics)

    This is commonly the case with elastomers, plastically-deforming materials and other fluids and biological soft tissue. Infinitesimal strain theory, also called small strain theory, small deformation theory, small displacement theory, or small displacement-gradient theory where strains and rotations are both small. In this case, the undeformed ...

  3. Finite strain theory - Wikipedia

    en.wikipedia.org/wiki/Finite_strain_theory

    In continuum mechanics, the finite strain theory—also called large strain theory, or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions inherent in infinitesimal strain theory. In this case, the undeformed and deformed configurations of the continuum are ...

  4. Strain rate imaging - Wikipedia

    en.wikipedia.org/wiki/Strain_rate_imaging

    Strain means Deformation, and is defined as relative change in length.The Lagrangian formula ε L = (L-L 0)/L 0 = ΔL/L 0, where L 0 is baseline length and L is the resulting length, defines strain in relation to the original length as a dimensionless measure, where shortening will be negative, and lengthening will be positive.

  5. Hemorheology - Wikipedia

    en.wikipedia.org/wiki/Hemorheology

    Blood viscosity is a measure of the resistance of blood to flow. It can also be described as the thickness and stickiness of blood. This biophysical property makes it a critical determinant of friction against the vessel walls, the rate of venous return, the work required for the heart to pump blood, and how much oxygen is transported to tissues and organs.

  6. Mechanical properties of biomaterials - Wikipedia

    en.wikipedia.org/wiki/Mechanical_properties_of...

    With that in mind, the time-dependent mechanical properties of tissues can be incredibly interdependent on molecular interactions and the chemical environment in which a specific tissue is native to. In comparison to other tissue, articular cartilage itself begins to enlarge when subjected to unloading and this puts the microstructure of the ...

  7. Haematopoietic system - Wikipedia

    en.wikipedia.org/wiki/Haematopoietic_system

    Haematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent haematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [ 10 ] [ 11 ] [ 12 ] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an ...

    The experimental drug puts semaglutide, the ingredient in Ozempic and the weight-loss drug Wegovy, together with a medicine called cagrilintide to make the combination Novo Nordisk calls CagriSema.

  9. Stress (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Stress_(mechanics)

    As in the case of an axially loaded bar, in practice the shear stress may not be uniformly distributed over the layer; so, as before, the ratio F/A will only be an average ("nominal", "engineering") stress. That average is often sufficient for practical purposes.
