Marginal and Internal Crown Fit Evaluation of CAD/CAM versus Press-Laboratory All-Ceramic Crown
The aim of this article is to evaluate marginal and internal fit between the all-ceramic crowns manufactured by the conventional press-dental laboratory and CAD/CAM systems. Methods: Tooth #14 was prepared per standard specification to receive an all-ceramic crown restoration. Forty-five prep tooth #14 were duplicated and randomly divided into three groups (n=15). All-ceramic CAD/CAM system (Gr...
متن کاملSyria in Iranian Press
The main inquiry of this article is how differently the news of uprisings in Bahrain, Yemen and Syria has been covered in conservative and reformist press. In the section of theories, a review of agenda-setting and social constructionism has been offered and using theory of constructivism the role of values, identity and norms in social uprisings has been studied.

The technological convergence between press and broadcasting throws into sharp relief the historically disparate regulation of the two sectors. As long as no political consensus on regulatory convergence can be reached, the question of how to distinguish between text-based a...
متن کاملOn Marginal Automorphisms of a Group Fixing the Certain Subgroup
Let W be a variety of groups defined by a set W of laws and G be a finite p-group in W. The automorphism α of a group G is said to bea marginal automorphism (with respect to W), if for all x ∈ G, x−1α(x) ∈ W∗(G), where W∗(G) is the marginal subgroup of G. Let M,N be two normalsubgroups of G. By AutM(G), we mean the subgroup of Aut(G) consistingof all automorphisms which centralize G/M. AutN(G) ...
متن کاملA Marginal Ergodic Theorem
Michael Lavine Duke University, Durham, NC, USA. Summary. In recent years there have been several papers giving examples of Markov Chain Monte Carlo (MCMC) algorithms whose invariant measures are improper (have infinite mass) and which therefore are not positive recurrent, yet which have subchains from which valid inference can be derived. These are nonergodic (not having a limiting distributio...
