AIM Propofol is a widely used anesthesia induction agent and is easily accessible in most healthcare facilities. Unlike regulated or schedule drugs, propofol is inconsistently tracked, leading to inaccurate inventories, incorrect billing, and unrecognized diversion. The goal of this project was to implement a new method of tracking propofol in a single setting, with the aim of accounting for 10...

The causality properties of space-time models with traversable wormholes are considered. It is shown that relativity principle cannot be applied to the motion of the wormhole’s mouths in the outer space and the dynamical wormhole transformation into the time machine is impossible. The examples of both causal and noncausal spacetime models with traversable wormholes are also considered. Some pro...

In a letter to the editor, Dane [2] argued that an error in statistics ‘makes any reasonable conclusions impossible’.

Search for keys may become incorrect. The classical method to implement deletion is to mark slots in hash table by three values: “free”, “busy”, “deleted”. That method is easy to implement, but there are some disadva...
