Studies on the effects of air ions on the functional efficiency of the extirpated tracheal strip have been extended to the trachea of the living rabbit, rat, and mouse. Animals exposed to high mobility (+) air ions administered via a tracheotomy aperture displayed: (a) Decreased ciliary activity. (b) Decline in mucus flow rate, sometimes reversed by prolonged exposure to (+) ions; a frequent drop in the volume of mucous secretion. (c) Contraction of the membranous posterior tracheal wall. (d) Increased vulnerability to trauma of cilia and mucosal blood vessels. Similar treatment with (-) air ions reversed (+) ion effects on ciliary activity, mucus flow, contraction of the tracheal smooth muscle. Continued (-) ion treatment raised the ciliary rate (invariably) and the mucus flow rate (often) above their initial levels. (+) Air ions administered to unoperated resting mice and rats increased the respiratory rate; (-) ions reversed this effect. Long exposure of unoperated ambulatory mice to (+) air ions produced: (a) Decreased ciliary activity. (b) No clear cut effect on mucus flow. (c) Contraction of the posterior tracheal wall. (d) Increased vulnerability of the mucosa to trauma. (-) Air ions increased ciliary activity but had no clear-cut effect on the mucus flow rate.

The characteristics of modified flow rate modulation metalorganic chemical deposition is studied. From observation with the atomic force microscope, the flatness of a InP homoepitaxial layer is improved to atomic scale by phosphine modulation metalorganic chemical vapor deposition. The full width at half maximum 5.6 meV of photoluminescence at 77 K can be achieved under optimum growth conditions. The satellite peak around the near band emission can also be reduced to a negligible quantity under optimum growth conditions. Also, MFME can improve the electrical characteristics of the epilayer with higher electron mobility and lower compensation ratio.
