1. The results show that for the 09G2 and 12GN2MFAYu steels for the identical values of ΔK and R, the rate of growth of the semielliptical crack at the deepest point of the front is higher than at the point of the front on the surface of the cyclica

1. With a more severe stress state in steels 09G2 and 12GN2MFAYu—i.e., plane strain as opposed to plane stress—the crack growth rate is higher for a given range of the SIF and there is a greater percentage of the brittle component in the fracture

Co-condensation of 2-aminopyridine, aromatic aldehydes, and ketones

Autor: N. P. Soldatova, V. I. Letunov

Publikováno v: Chemistry of Heterocyclic Compounds. 23:861-864

The co-condensation of 2-aminopyridine with aromatic aldehydes and ketones proceeds via the initial formation from the amine and the benzaldehydes of (2-pyridylamino)aryl carbinols, which then react with p-nitroacetophenone to give 3-aryl-1-(4-nitrop

Interaction of 3-arylidenaminocarbazoles with antipyrine

Autor: T. P. Shulyat'eva, V. V. Misenzhnikov, V. I. Letunov

Publikováno v: Chemistry of Heterocyclic Compounds. 19:1310-1312

The interaction of 3-arylidenaminocarbazoles with antipyrine in the presence of catalytic amounts of acid leads to the formation of derivatives of indolo[3,2-f]-pyrazolo[4,3-c]quinoline.
