conclusions this approach may be an appropriate approach to the zygomatic arch in the zmc fractures and eliminates the use of the coronal flap. introduction zygomatic arch fractures are common injuries in the maxillofacial injuries. sometimes it is necessary to fix the unstable fragments of the zygomatic arch. case presentation we introduce a combination of transconjunctival and lateral canthot...

Cerebral aneurysms are bulges appearing on brain arteries. The development, growth and rupture has been intensively studied using numerical tools. We present a series of studies covering many of the open questions related to the boundary conditions used in numerical simulations, namely the inlet, outlet and the wall. The effect of boundary conditions cannot be overestimated; yet it received muc...

We obtain an upper bound on the convective heat transport in a heated from below horizontal fluid layer of infinite Prandtl number with rigid lower boundary and stress-free upper boundary. Because of the asymmetric boundary conditions the solutions of the Euler-Lagrange equations of the corresponding variational problem are also asymmetric with different thicknesses of the boundary layers on th...

We review the literature on swimming in complex fluids. A classification is proposed by comparing length and time scales of a swimmer with those nearby obstacles, interpreted broadly, extending from rigid or soft confining boundaries to molecules which confer bulk fluid stresses. third dimension concentration swimmers, incorporates fluids whose complexity arises purely collective motion organis...

Diffusion is a slow transport mechanism and advective transport tends to dominate in large-size systems. An alternative transport mechanism is explored herein, whereby zero time-average cyclic fluid flow is compounded with pore-scale mixing to render effective transport. Two one-dimensional cyclic flow cases are analyzed: a rigid porous network with two open boundaries subjected to cyclic flow ...

Spatiotemporal boundary formation (SBF) is the perception of form, global motion, and continuous boundaries from relations of discrete changes in local texture elements (Shipley and Kellman, 1994). In two experiments, small, circular elements underwent small displacements whenever an edge of an invisible (virtual) object passed over them. Unlike previous studies that examined only rigidly trans...
