✦ Synopsis

The JR curve is getting more and more use in evaluating a material's resistance to crack growth, but the standard method for measuring it needs several specimens. In this paper, a new method is proposed to determine the JR curve of mild steel from the load-displacement record of a cracked TPB specimen and a blunt notched TPB specimen. The JR curve obtained using the proposed method is in accordance with the JR curve obtained by the standard multiple specimen method.

A new method for the synthesis of amidines is presented using N-acetylcysteine as a catalyst. The key advantage of this new method is that it is compatible with a large number of functional groups. It allows the synthesis of amidines in complex molecules containing acid-labile groups, base-labile ce
