Reichsrecht and Volksrecht in Theory and Practice: Roman Justice in the Province of Egypt (P.Oxy. II 237, P.Oxy. IV 706, SB XII 10929)

This article offers a perspective on the traditional debate over the nature of the legal order in the Roman Empire, the role of Roman law in Roman provincial jurisdiction and the status of local laws and practices under Roman rule. These questions are explored through a series of case studies of papyrological evidence from Roman Egypt, including the jurisdictional edict of Petronius Mamertinus (SB XII 10929) and the well-known petition of Dionysia (P. Oxy. II 237).This article offers a perspective on the traditional debate over the nature of the legal order in the Roman Empire, the role of Roman law in Roman provincial jurisdiction and the status of local laws and practices under Roman rule.

Direct Numerical Simulation of a separated channel flow with a smooth profile

A direct numerical simulation (DNS) of a channel flow with one curved surface was performed at moderate Reynolds number (Re_tau = 395 at the inlet). The adverse pressure gradient was obtained by a wall curvature through a mathematical mapping from physical coordinates to Cartesian ones. The code, using spectral spanwise and normal discretization, combines the advantage of a good accuracy with a fast integration procedure compared to standard numerical procedures for complex geometries. The turbulent flow slightly separates on the profile at the lower curved wall and is at the onset of separation at the opposite flat wall. The thin separation bubble is characterized with a reversal flow fraction. Intense vortices are generated near the separation line on the lower wall but also at the upper wall. Turbulent normal stresses and kinetic energy budget are investigated along the channel.Comment: 23 pages, submitted to Journal of Turbulenc

Undulation instabilities in the meniscus of smectic membranes

Using optical microscopy, phase shifting interferometry and atomic force microscopy, we demonstrate the existence of undulated structures in the meniscus of ferroelectric smectic-C* films. The meniscus is characterized by a periodic undulation of the smectic-air interface, which manifests itself in a striped pattern. The instability disappears in the untilted smectic-A phase. The modulation amplitude and wavelength both depend on meniscus thickness. We study the temperature evolution of the structure and propose a simple model that accounts for the observed undulations.Comment: Submitted to PR
