Cover: The cover presents a pseudo-color plot of the calculated density distributions of molecules in the NO(A) state (left), and of O(3P) (middle) and N(4S) (right) atoms in an N2-O2 discharge-afterglow. The flow of plasma enters from the left, along the chamber axis (z=140 mm) and the graphs represent the x-z plane at fixed y. The concentration of NO(A) species, the ones that emit biocidal UV photons from the NOγ molecular system, is nearly uniform at p=2 Torr, our standard pressure for sterilization, but calculations predict a strong non-uniformity at 10 Torr. Further details can be found in the article by K. Kutasi,* B. Saoudi, C. D. Pintassilgo, J. Loureiro, and M. Moisan on page 840.
