In bearing applications, the presence of stray and parasitic currents in combination with lubricants has been studied for almost a century found to cause fluting corrugation damages under high current densities. However, recent research suggested that at low densities (<1 mA/mm2) specific operating conditions, electrical discharges can substantially reduce life due formation white etching cr...

A dynamical theory of geophysical precipitation pattern formation is presented and applied to irreversible calcium carbonate (travertine) deposition. Specific systems studied here are the terraces and domes observed at geothermal hot springs, such as those at Yellowstone National Park, and speleothems, particularly stalactites and stalagmites. The theory couples the precipitation front dynamics...

Wound dressings that can be formed in situ offer several advantages over the use of preformed dressings such as conformability without wrinkling or fluting in the wound bed, ease of application and improved patient compliance and comfort. Here we describe such an in situ forming hydrogel wound dressing from gelatin, oxidized alginate and borax. Periodate oxidized alginate rapidly cross-links pr...

We consider fluting oscillations in a thin straight expanding magnetic flux tube the presence of background flow. The is divided into core region that wrapped transitional region, where damping takes place. method multiple scales used for derivation system governing equations. This applicable to study both standing and propagating waves. Furthermore, equations obtained tubes with sharp boundary...
