...Abstract Abstract An investigation of a Stirling engine after an aborted test run revealed that the regenerator screens had suffered substantial damage. During the run, the individual screens oscillated as the helium working fluid was shuttled through the regenerator. In localized areas, the 41...

... As long as bone healing progresses normally, an implant will not undergo fatigue fracture, because the loading decreases successively as the bone becomes more supportive. Normal bone has a remarkable inherent regeneration potential. However, certain conditions must be fulfilled so that the bone heals...

... in petrochemical plants. In coking/decoking cycles, tubes are subjected to thermal fatigue and deposited coke swept away by decoking gas [ 3 ]. After long time of operation, the oxide layer is frequently removed and regenerated. Because of this process, three different layers were formed in the inner cross section...
