Change is not made without inconvenience, even from worse to better. Richard Hooker, as quoted in the preface of Samuel Johnson's A Dictionary of the English Language Oh, so they have internet on computers now! Homer Simpson It is with great pleasure that I announce the rebirth of the former print journal of the Canadian Geriatrics Society as a new online publication, the Canadian Geriatrics Jo...

Turn and Face the Strange... Ch-ch-changes

Phase transitions are abrupt changes in the macroscopic properties of a system. Examples of the phenomenon are familiar: freezing, condensation, magnetization. Often these transitions are particularly dramatic, as when solid objects composed of the silvery metal gallium vanish into puddles when picked up (the temperature of the hand is just enough to raise gallium’s temperature past its melting...

Constraining the Environment of Ch+ Formation with Ch+ 3 Observations

The formation of CH+ in the interstellar medium (ISM) has long been an outstanding problem in chemical models. In order to probe the physical conditions of the ISM in which CH+ forms, we propose the use of CH3 observations. The pathway to forming CH + 3 begins with CH +, and a steady-state analysis of CH3 and the reaction intermediary CH2 results in a relationship between the CH + and CH3 abund...

Cyclic Ch ronopotentiometry

b An electroanalytical method for studying electrode reactions, called cyclic chronopotenticmetry, in which the applied current is successively reversed a t each t,*ansition, is proposed. A circuit for carrying out automatic current reversals is described. T h e equations for the successive transition times for linear diffusion in a singie clmponent system have been derived and solved, and t h ...
