Effects of gravel columns on static and dynamic properties of sand: a laboratory investigation [PDF]
Scientific ReportsVibrated stone columns (composed of gravel in this study) are widely used for ground improvement. However, the composite behavior of sand–gravel composite columns (SGCC) under combined static and dynamic loading is not yet fully understood.

Reduced Shear Modulus and Altered Lamellar Morphology of the Outer Annulus Fibrosus in Painful Intervertebral Disc Degeneration Compared With Tissue From Non‐Surgical Controls [PDF]
JOR SpineBackground Stability of the spine and intervertebral disc (IVD) integrity is enabled by the highly organized fibrocartilaginous annulus fibrosus (AF). The shear properties of the AF are important in maintaining IVD integrity.
