Studies focusing exclusively on the impact of the Greek language on Old Slavonic and, specifically, Bulgarian, come few and far between, and the subject still offers much uncharted territory for contemporary philological and linguistic research. Given this state of affairs, this study by Charalampos Symeonides is a welcome and important contribution to the field. In essence, it continues the author's longstanding research interest in the mutual interaction of Greek and Bulgarian, and seeks to present the results of his investigations into (...) the consequences of this interaction on the noun systems of Old Church Slavonic and Bulgarian – investigations that to date have appeared only in scattered articles.

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.
