The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...

The Front Cover shows a drawing of the Rocky Mountains in Alberta, Canada. new frustrated Lewis pair (FLP) [iPr2P(C13H8)BCy2] is depicted at center drawing. This molecule contains an unusually reactive B−C bond which behaves as “masked” FLP. molecules to its left and right depict FLP's reaction products with Cl2PPh H3N•BH3, respectively; these demonstrate ability activate P−Cl N−H bonds. raccoo...

A proximity drawing of a graph is a straight-line drawing where adjacent vertices are represented by points that are deemed to be close according to some proximity measure. A rectangle of innuence drawing is a proximity drawing where the measure is based on the concept of rectangle of innuence. Given two points u and v, the rectangle of innuence of u and v is the axis-aligned rectangle having u...

AIM To develop a simple method to assess the level of anxiety by using children's drawings and correlating them with Frankl's behavior rating scale. MATERIALS AND METHODS A total of 178 patients aged of 3 to 14 years were handed out two-page forms which contained three sections on coloring and drawing, along with general information, and Frankl's behavior rating scale for the visit. The three...
