We show that any finite structure consistent with the axioms of jump uppersemilattices with least element can be embedded into the jump uppersemilattice of Turing degrees with least element. This result implies that the existential theory of this structure is decidable.

A recently published paper [T. Došlić, this journal 3 (2012) 25-34] considers the Zagreb indices of benzenoid systems, and points out their low discriminativity. We show that analogous results hold for a variety of vertex-degree-based molecular structure descriptors that are being studied in contemporary mathematical chemistry. We also show that these results are straightforwardly obtained by u...

Unequal access to higher medical degrees, which are important for career advancement, is a problem that is likely to plague UK medicine as integration within Europe proceeds. This paper analyses the characteristics of M.D.s at the Royal Free Hospital School of Medicine and proposes a solution of creating a common European doctorate.
