A method of testing the transverse tensile strength of wound articles

A theoretical and experimental justification is provided for a method of determining the transverse tensile strength of composites on the basis of bending tests on a segment of a circular ring. Test data obtained by different methods are compared.Moscow Power Engineering Institute. Translated from Mekhanika Polimerov, No. 4, pp. 759–761, July–August, 1973.     

Absorption spectra of ionic complexes containing triarylmethane dyes

The peak strength and position of the absorption bands are found to be correlated with the stability and association strength of the complexes. The results confirm concepts on the electron densities in the components.We are indebted to N. D. Sokolov for a useful discussion.     

Synthesis of biologically active analogs of luliberin with shortened amino acid sequences

Two new analogs of the releasing factor of the luteinizing hormone with shortened amino acid sequences have been synthesized by the methods of classical peptide chemistry. The influence of the preparations on the action of chorionic gonadotropin and on the course of processes of ovulation in experimental animals has been studied. The promising nature in this direction of the search for active analogs for luliberin has been shown.
