Definition of rheology in English:

rheology

noun rɪˈɒlədʒirēˈäləjē
mass noun
  • The branch of physics that deals with the deformation and flow of matter, especially the non-Newtonian flow of liquids and the plastic flow of solids.

    Example sentencesExamples
    • A molecular explanation for turgor-dependent changes in wall rheology is proposed in the quantitative molecular model of Passioura and Fry.
    • We can do that because the topography that a planet can support is dependent upon structure and rheology.
    • The crowding could lead to polymerization or cross-linking events between macromolecules that might account for a change in rheology of the cytoplasm other than that caused by actin polymerization.
    • The power-law rheology seen here, as in a number of cellular systems, rules out any single timescale.
    • None of these theological features were observed in our cell measurements, thereby suggesting that F-actin models are too simple to account for the complex rheology of the cells.
    • The stiffness of the constituent polymers of a mucous gel will also have a direct influence on the structure of the gel, particularly on characteristics such as rheology, film stability, and pore size.
    • Compactability is a measure of how easily the concrete is compacted and is the most-abused characteristic of vertical concrete's rheology.
    • Overall, the deformation behavior and power-law rheology indicate an extremely broad range of timescales that underlie reversible changes in nuclear structure.
    • We did not rely on force curve analysis for quantitative evaluation of complex cellular rheology but instead used the indentation modulation procedure described below.
    • Twenty-two papers are grouped into four contextual sections - the effect of fluids, microstructures and textures, deformation mechanisms and rheology and tectonics.
    • Thus, consistent with previous findings, these dense cells are likely to contribute to poor rheology of sickle cell blood at all O2 saturations.
    • We lack quantitative sedimentological and structural data on the Somma-Vesuvius debris avalanches, but we can make some interpretations regarding their rheology.
    • Previous workers have attributed these differences to changes in rheology, i.e. brittle faulting in sandstones v. more ductile folding and faulting in dolostones.
    • We explore the impact of rheology on actin-dependent cytoplasmic contraction, and find that although microtubules modulate contractile forces in vitro, their interactions are not purely mechanical.
    • Knowledge of polymer rheology is essential in maintaining uniform textures in molded products such as, for example, an ice cream sandwich.
    • In the case of taxol-stabilized extracts, we measure little difference in network rheology as compared to the untreated gels, yet observe striking differences in their contractile behavior.
    • As with the cytoskeletal networks, rheology thus provides a valuable tool for studying networks composed of micrometer-scale clusters, where light scattering studies fail.
    • They can inform us about the origin and ongoing development of many parts of the ocean basins, about former and current plate movements, about upper-Earth rheology, and about postglacial sea-level rise, among other processes.
    • Post et al. showed that quartz rheology is sensitive to water fugacity, but the above extrapolations do not apply to identical values of water fugacity.
    • In this model, plant cell walls could be visualized as a ‘tangle’ of microfibrils, with wall rheology determined by spatial constraint upon further microfibril movement.

Derivatives

  • rheological

  • adjective rɪəˈlɒdʒɪk(ə)l
    • In comparison with rheological and theoretical studies on viscoelasticity of actin gels, the properties of orientational ordering of actin have been less studied, both theoretically and experimentally.
      Example sentencesExamples
      • After the stochastic cytoskeletal detachment event, the tether was found to extend according to a viscous shear-thinning rheological power-law model.
      • In one case, the relationship between the force and the displacement was not linear which corresponded to a viscoelastic rheological behaviour.
      • Low shear viscosity measurements are only very sensitive to both the rheological history of the suspension and viscometer geometry only for a strong deformable red cells aggregation.
      • Because it is a rheological boundary, and rheological properties depend, inter alia, on strain rate, the thickness also depends on strain rate.
  • rheologist

  • noun

Origin

1920s: from Greek rheos 'stream' + -logy.
