The Tate conjecture for K3 surfaces over finite fields

Artin's conjecture states that supersingular K3 surfaces over finite fields have Picard number 22. In this paper, we prove Artin's conjecture over fields of characteristic p>3. This implies Tate's conjecture for K3 surfaces over finite fields of characteristic p>3. Our results also yield the Tate conjecture for divisors on certain holomorphic symplectic varieties over finite fields, with some restrictions on the characteristic. As a consequence, we prove the Tate conjecture for cycles of codimension 2 on cubic fourfolds over finite fields of characteristic p>3.Comment: 20 pages, minor changes. Theorem 4 is stated in greater generality, but proofs don't change. Comments still welcom

Clinical Studies of Dental Cements: I. Five Zinc Oxide-Eugenol Cements

Five zinc oxide-eugenol cements of varying compressive strengths, similar in other qualities, were used in a blind clinical study of luting temporary restorations. On the basis of retention, ease of removal when required, and ease of cleaning the restoration, two of the cements were found to serve best.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/67420/2/10.1177_00220345680470051301.pd
