Some Remarks on Axiomatizing Logical Consequence Operations

In this paper we investigate the relation between the axiomatization of a given logical consequence operation and axiom systems defining the class of algebras related to that consequence operation. We show examples which prove that, in general there are no natural relation between both ways of axiomatization.

Patients' experience of surgical accidents.

How the helicopter emergency medical system best supports avalanche rescue missions is controversial. AIM OF THE STUDY To study advantages and limitations of the early dispatch of emergency medical helicopters after avalanche accidents. METHODS Data on rescue mission ch...

Remarks on the Wiener Polarity Index of Some Graph Operations†

TheWiener polarity indexWp(G) of a graphG of order n is the number of unordered pairs of vertices u and v of G such that the distance dG(u, v) between u and v is 3. In this paper the Wiener polarity index of some graph operations are computed. As an application of our results, the Wiener polarity index of a polybuckyball fullerene and C4 nanotubes and nanotori are computed. AMS Mathematics Subj...
