Segmented Therapeutic Delivery via Acoustic Microbubble Relay

open access: yesAdvanced Intelligent Systems, EarlyView.
An acoustically driven, modular segmented delivery system is presented to overcome mechanical limitations of conventional microcatheters. Oscillating microbubbles generate directional streaming that enables continuous, targeted transport across open, angled segments.

Oscillatory Maxwell-Cattaneo Ferroconvection in a Densely Packed Rotating Porous Medium Saturated with a Viscoelastic Magnetic Fluid

open access: yesEast European Journal of Physics
The combined effect of second sound and the viscoelasticity is examined using the classical stability analysis on the onset of rotating porous medium ferroconvection. Local thermal equilibrium is assumed between the solid matrix and fluid.

Cauchy problem for the non-newtonian viscous incompressible fluid [PDF]

open access: yesApplications of Mathematics, 1996
The article is devoted to the problem of the existence, uniqueness and regularity of the weak solution of the Cauchy problem for non-Newtonian viscous incompressible fluid. The Cauchy stress tensor has a form \[ \tau=-pI-\tau (e)-2\mu_1\Delta e, \tag{1} \] where \(e\) is the deformation velocity tensor and \(\tau(e)\) satisfies the following condition \
