Planktonic communities and chaotic advection in dynamical models of Langmuir circulation [PDF]

open access: yes, 1998
A deterministic mechanism for the production of plankton patches within a typical medium scale oceanic structure is proposed and investigated. By direct numerical simulation of a simple model of Langmuir circulation we quantify the effects of unsteady ...

Hyaluronan and Hyaluronidase, which is better for embryo development? [PDF]

open access: yes, 2016
Our aim was to examine size-specific effects of Hyaluronan (HA) on preimplantation embryo development. We investigated the effects of Hyalovet (HA, 500–750 kDa; the size produced by HA synthase-3, which is abundant in the oviduct), or HA treated with ...

Rotational dynamics of a superhelix towed in a Stokes fluid

open access: yes, 2007
Motivated by the intriguing motility of spirochetes (helically-shaped bacteria that screw through viscous fluids due to the action of internal periplasmic flagella), we examine the fundamental fluid dynamics of superhelices translating and rotating in a ...
