Viscoelastic properties of ferrofluids

Physical Review E, 2010
The paper deals with theoretical study of non linear viscoelastic phenomena in ferrofluids placed in magnetic field. Our attention is focused on the study of nonstationary flow and Maxwell-like relaxation of the macroscopical viscous stress after alternation of the shear rate. We propose that these phenomena can be explained by finite rate of evolution

Viscoelastic properties of nucleus pulposus

Journal of Back and Musculoskeletal Rehabilitation, 1997
Although there have been many studies on the mechanical properties of the annulus fibrosus [1], the fibrous outer layers of the intervertebral disc, there have been fewer studies published on the mechanical properties of its soft centre, the nucleus pulposus [2-4].

Viscoelastic properties of human dentin

Journal of Biomedical Materials Research, 1975
AbstractStress relaxation measurements were performed on thick‐walled cylinders of radicular human dentin. The experimentally measured relaxation moduli were used to obtain an approximation to the logarithmic distribution functions of relaxation times. This distribution function was used to predict the behavior of other viscoelastic properties.

Viscoelastic Properties of the Cell Nucleus

Biochemical and Biophysical Research Communications, 2000
Mechanical factors play an important role in the regulation of cell physiology. One pathway by which mechanical stress may influence gene expression is through a direct physical connection from the extracellular matrix across the plasma membrane and to the nucleus.

Viscoelastic Properties of Particle Gels

Journal of Colloid and Interface Science, 1999
The effect of strength of attraction and volume fraction on the mechanical properties of alumina particle networks were investigated. Alumina particle gels were formed reversibly and in situ in the rheometer by cooling alumina particle suspensions with adsorbed poly(12-hydroxy stearic acid) suspended in a marginal solvent, hexanol.

Viscoelastic properties of cumulus oöphorus

Biorheology, 1976
An experimental technique suitable for the determination of the rheological properties of minute, biological viscoelastic solid specimens is presented. This technique is employed to ascertain the viscoelastic properties of the rabbit cumulus oöphorus. The experimental results when analyzed using the finite theory of elasticity reveal that the cumulus ...

VISCOELASTIC PROPERTIES OF NETWORKS

International Journal of Modern Physics C, 2009
A network was characterized by its viscoelastic properties. The viscoelastic property indicates the deformations or changes in the shape and in the internal structure during the evolution of a network. The change in the direction of motion was taken as elastic deformation and the change in the vertical direction as viscous deformation.

Viscoelastic properties of fibrin clots

Biorheology, 1973
Elastic and viscous properties of fibrin clots were measured in the cone-plate test section of a Weissenberg Rheogonimeter. The tests applied included forced oscillations, free vibrations, and stress relaxation, all in shear. Two classes of clots were studied: (i) ligated clots, formed with the presence of the enzyme fibrinoligase, and (ii) non-ligated

MR imaging of viscoelastic properties

Journal of Magnetic Resonance Imaging, 1995
AbstractMechanical waves in magnetic resonance imaging, which have been suggested for possible clinical applications, were analyzed with regard to imaging of the viscoelastic properties of large objects. The method is based on the Larmor frequency modulation caused by the application of mechanical waves.

Viscoelastic Properties of Microtubule Networks

Macromolecules, 2007
Microtubules are filamentous protein biopolymers found in eukaryotic cells. They form networks that guide active intracellular transport and support the overall cell structure. Microtubules are very rigid polymers, with persistence lengths as large as a millimeter.
