In some recent papers, it has been shown that electrovac spacetimes may sometimes be interpreted as space-time filled with a viscous fluid—one such spacetime being the Kerr-Newman metric. Here the possible fluid motion in that case is studied in some detail and some interesting features of the motion in the black hole region are pointed out.

The atom superposition and electron delocalization molecular orbital theory has been used to study the effect of alkali additives and steps on the dissociative chemisorption of CO molecule on Ni(001) surface. We have found that with increasing concentration of alkali atoms the CO bond length increases, the CO bond strength weakens and the CO dissociation barrier decreases. The results are in qualitative agreement with experimental results. The steps have also been found to reduce the dissociation barrier quite significantly compared with the reduction by alkali additives.

Temperature fluctuations have been measured in the edge region of the SINP tokamak. We find that these fluctuations have a comparatively high level (30–40%) and a broad spectrum. The temperature fluctuations show a quite high coherence with density and potential fluctuations and contribute considerably to the anomalous particle flux.
