Mikhail TAMM (LPTMS, Paris-11 Orsay): "Clover-leaf structures in associating polymers: a toy model for RNA folding . The clover-leaf structures under discussion are defined as follows. The polymer is supposed to bear numerous sticky centers along the chain, these centers being capable of forming thermoreversible bonds with each other. ... Now, we say that some given structure belongs to the clover-leaf type if the archs on the corresponding diagram do not intersect each other. ...

. Authors: A.A. Suchkov , V.A. Marakov . Journal: Pis'ma Astron. Zh., 1976, v.2, p.38-385. Metallisity function of globular clusters in the Galaxy is constructed. It is found to have three "humps". This leads to a conclusion that there were three metal enrichment outbursts during the period of globular cluster formation. The constraints on the nature of metal sourses and on the early evolution of Galaxy are considered.
