Reasoning and Representation: the Sketching of Organic Chemical Reaction Mechanisms

For nearly a century organic chemists have developed a method of sketching chemical reaction mechanisms in order to reason-out the structural transformations that convert one set of molecules into another. Known informally as pushing electrons (or curly arrows), it is a form of chemical illustration in which a sequence of structures is drawn to represent the movement of electrons and nuclei fro...

A Report on 40 Cases

Forty patients with tuberculosis of the lower cervical spine (second to seventh cervical vertebrae) have been reviewed. Pain and stiffness were important and dominant symptoms. Two types of disease were recognised. In children under 10 years old involvement was extensive and diffuse with the formation of large abscesses. In patients over 10 the disease was localised and produced less pus, but w...

Well Solved Cases Of Probabilistic Traveling Salesman Problem

The Probabilistic Traveling Salesman Problem is in general NP-Hard, the objective of this paper is to look for particular cases which can be solved in an easy way. First we give the relation between the two problems deterministic and probabilistic. Second, we study the stability of the deterministic problem. We prove that in the small traveling salesman problem, several tours were optimal, but ...
