This in vitro study evaluated the survival rate and fracture resistance of maxillary central incisors restored with different post and core systems. The post and core systems investigated were a prefabricated high precious metal post with cast core (group A), zirconia post with a prefabricated bonded ceramic core (group B), and a resin-ceramic interpenetrating phase composite post (experimental...

Measurements of variables Dependent variable: firm performance Both accounting and market measures of firm performance are used to investigate the relationship between forms of shareholders and firm performance. The most common accounting profitability measure is return on assets. 23 Considering discretionary accounting measures that are the common critique for accounting data, core operat...

Fluted-core sandwich structures, consisting of fiber-reinforced plastics, are frequently utilized in the aerospace industry owing to their excellent strength-to-weight ratio. However, thin-walled structures prone local buckling, which reduces load-bearing capacity and eventually leads material failure. The current study presents analytical models for predicting buckling fluted-core panels subje...
