40 LLE Review, Volume 97 Introduction Glass-ceramics are attractive structural materials due to their good mechanical properties, chemical stability at higher temperatures, and tailored microstructures via appropriate heat treatments. In the cold working of glass-ceramics, several options are available: loose-abrasive grinding (lapping, at fixed nominal pressure) or deterministic microgrinding ...

The breeder thermal performances under a purge line break have been analyzed for two blanket design options: a blanket design using a packed breeder bed and a blanket design using a sintered breeder product. Under a purge line break open to a vacuum environment, the packed bed breeder temperature exceeds its operating temperature limit at a faster rate than that of the sintered breeder blanket ...

This paper explores the effects of language contact in nominal morphology central Sicilian dialects. In particular, this study is concerned with contact-induced changes related to distribution three plural formatives that give rise competition between different inflectional classes respect a number lexemes. It shown sociolinguistic factors such as speaker age account for competing forms and hig...

The pore-level two-phase fluids flow mechanism needs to be understood for geological CO2 sequestration as a solution to mitigate anthropogenic emission of carbon dioxide. Capillary pressure at the interface of water–CO2 influences CO2 injectability, capacity, and safety of the storage system. Wettability usually measured by contact angle is always a major uncertainty source among important para...

It is important to study joint contact mechanics in order to understand the human joint function and degeneration. In previous studies, the cartilage behavior was investigated using computational method assuming the cartilage to be flat and an ideal thickness. But, this assumption may not appropriate because the joint is naturally curved and the cartilage thickness varies across the articular c...

Current-Pressure (I/P) transducers are effective pressure regulators that can vary the output pressure depending on the supplied electrical current signal, and are commonly used in pneumatic actuators and valves. Faults in current-pressure transducers have a significant impact on the regulation mechanism, and therefore, it is important to perform diagnosis to identify such faults. However, ther...

The vertical and rocking impedances of a rigid foundation resting on a semi-infinite transversely isotropic medium are obtained in the frequency domain. In the present approach, the contact pressure distribution on the soil foundation-interface is approximated by a linear combination of known pressure patterns. It is shown herein that the approximate solutions of spatial displacement distributi...
