bed rails, the bed surface, and the supply cart, on the basis of their observed frequency of contact.12 Developing an un-derstanding of which sites are more likely to be contaminated with pathogens can guide infection control practice and direct new innovations.

Leed studies on a clean and contaminated Pd?110?

Low energy electron diffraction from a clean and carbon contaminated Pd{110} surface has been studied over the temperature range 100-800 K and evidence for a phase transition on the clean surface near 250 K is found. Residual carbon on or in the surface layer causes shifts in the energies of peaks in intensity versus energy spectra which correspond to an average outward expansion of about 4% ...
