The Bauschinger effect in thin sputter-deposited Al and Cu films is studied by isothermally deforming the films alternately in tension and compression. Passivated films exhibit an unusual Bauschinger effect with reverse flow already occurring on unloading, while unpassivated films show little or no reverse flows when the film is fully unloaded. 2005 Acta Materialia Inc.

In this work, the suitability of several techniques for monitoring a reverse-flow reactor system are studied. Reverse reactor systems are operated by periodically reversing the direction of the flow inside the reactor [1],[2]. One benefit of a reverse-flow configuration is that, for exothermic reactions, the system exhibit a heat-trap effect [3] where the temperature profile across the reactor ...

For gamma-ray bursts (GRBs) born in a stellar wind, as the reverse shock crosses the ejecta, usually the shocked regions are still precipitated by the prompt MeV γ−ray emission. Because of the tight overlapping of the MeV photon flow with the shocked regions, the optical depth for the GeV photons produced in the shocks is very large. These high energy photons are absorbed by the MeV photon flow...

The authors assessed the long term clinical and functional results following local flap coverage (medial plantar flap, peroneal reverse flow island flap, posterior tibial reverse flow flap) in 11 patients who developed wound complications after open repair of a ruptured Achilles tendon. At the latest follow-up, seven patients had achieved a good result, having returned to their pre-injury activ...

We have shown that a reverse energy flow (negative projection of the Poynting vector onto optical axis) at sharp focus an vortex with topological charge 2 and left-hand circular polarization arises because axial spin has negative axis is greater in magnitude than positive orbital (canonical flow). Also, using Richards-Wolf formulas, it when focusing left-handed circularly polarized light, regio...
