Metallic foams and cellular solids represent a relatively new class of materials with perspective applications in lightweight structures, in acoustic and thermal management, in energy-absorbing parts, etc. Efficient use of these advanced materials requires detailed information on their mechanical behaviour, even when their primary use is not linked to mechanical loading (e.g., thermal insulatio...

statement of problem: the restoration of the teeth should have enough ability to withstand masticator forces while preserving as much tooth structure as possible. purpose: the purpose of this study was to compare the effects of light-heat cured composite with light cured composite restorations on fracture resistance of the restored teeth. materials and methods: forty healthy maxillary premolar ...

micro silica (ms) is an extremely fine, spherical powder that is used as an additive for improving concrete performance. it is obtained as a by product of silicon metal and ferrosilicon alloy production.  due to its pozzolanic nature, micro silica can be used to enhance the qualities of both  fresh  and  hardened  concrete. addition of micro silica into the concrete as a cement replacement, dec...

In real-world applications, controllers must operate in the presence of an untold number of off-nominal conditions that either were not or could not be accounted for during formal synthesis. Engineers compensate for these real-world effects by extensive simulation and testing. Only after extensive evaluation and validation can a controller be accepted for critical applications. In addition, it ...

BACKGROUND Zirconia materials are known for their optimal aesthetics, but they are brittle, and concerns remain about whether their mechanical properties are sufficient for withstanding the forces exerted in the oral cavity. Therefore, this study compared the maximum deformation and failure forces of titanium implants between titanium-alloy and zirconia abutments under oblique compressive force...
