In Vitro Mechanical Tests for Modern Dental Ceramics
Frontiers in Dentistry, 2006 The fracture resistance of all-ceramic restorations is one of the major concerns in clinical applications of these materials. Before initiating a time-consuming and costly clinical investigation, an in vitro study can help to estimate the in vivo ...

Biography of Are Tsirk (1937-2015): Flintknapper and scholar
Journal of Lithic Studies, 2015 Are Tsirk was as much a scholar as he was a flintknapper. These disciplines were intertwined and expressed in his experimental research, by way of his exploration of fractography, and his replication of stone tools which spanned the archaeological record

Polymer International, Volume 75, Issue 9, Page 804-817, September 2026.Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

Failure Investigation of Alloy 625 Sockolets After Prolonged Service in an Ammonia Cracker Unit
Materials and Corrosion, Volume 77, Issue 8, Page 1375-1384, August 2026.The failure of the sockolets was caused by intergranular cracking and fracture. The thick and highly brittle nitrided layer formed intergranular surface cracks, which propagated along grain boundaries into the base alloy substrate due to the presence of brittle Cr‐rich carbides. ABSTRACT Several sockolets of Alloy 625 operating at 540°C in contact with
