On the Transversal Intersection Curve of Spacelike and Timelike Surfaces in Minkowski 3-Space
Özet
In this paper, we study the local properties of the intersection curve of a spacelike surface and a timelike surface. We derive the curvature vector, curvature and torsion for the transversal intersection for parametric-parametric intersection problem. Furthermore, we investigate some characteristic features of the intersection curve.

Surface conditioning methods and polishing techniques effect on surface roughness of a feldspar ceramic
Sarac, Y. Sinasi; Elekdag-Turk, Selma; Sarac, Duygu; Turk, Tamer (E H Angle Education Research Foundation, Inc, 2007)Objective: To investigate the effects of three surface conditioning methods on shear bond strength (SBS) and on surface roughness (Ra) of a feldspathic ceramic, and to compare the efficiency of three polishing techniques. ... -
Effects of surface conditioning on bond strength of metal brackets to all-ceramic surfaces
Turk, Tamer; Sarac, Duygu; Sarac, Y. Sinasi; Elekdag-Turk, Selma (Oxford Univ Press, 2006)The aim of this study was to determine the effectiveness of bonding brackets to ceramic restorations. Sixty feldspathic and 60 lithium disilicate ceramic specimens were randomly divided into six groups. Shear bond strength ... -
