The 1994 April VLBA observations were made as part of a larger program of observation intended primarily to study the Galactic center, and we wish to acknowledge the contributions of Don Backer who participated in the initial reductions of these data which we have used in part in this paper. We also thank Tom Balonek, L. Botti, and Z. Abraham for providing data in advance of publication as well as Roger Blandford and Juan Uson for helpful discussions. This work was partially supported by NSF grant AST 91-21889.

N2 - The fracture toughness of a crystalline silicon carbide fiber, Tyranno-SA®, was determined by introducing an artificial notch directly into the fiber test specimens using a focused-ion (Ga +) beam. The relation between fracture strength and notch size was determined experimentally, while the relation among the notch size, fiber diameter, applied stress at infinity, and stress intensity factor was analyzed by the finite element method. By applying the analyzed result to the experimental results, the fracture toughness of the fiber was determined to be 2.7 ±0.4 MPa√m.
