This paper seeks to present findings from a longitudinal action research study aimed at exploring one such innovation. Little is known about the micro-level impact of health service innovations over time. The paper shows that action research is a participatory approach ideally suited to...

A highly collimated beam of protons (<InlineEquation ID="Equ1"> <EquationSource Format="TEX">$\approx$</EquationSource> </InlineEquation>1 MeV) entering the channel of a monocrystal film forms at a certain depth an extremely sharp (0.005 nm) and relatively long (some monolayers of the crystal) focusing area where the increase of the flux density can reach thousand times.
