Theory of Gas Ionization by Intense Electromagnetic Fields

The distribution function of the electrons produced in the interaction between an intense electromagnetic wave and a neutral gas is derived and is shown to be nonequilibrium and anisotropic. By assuming that the time scale of gas ionization is much greater than the field period, it is shown that the electron distribution function formed in microwave and optical discharges has sharp anisotropy a...

Malaria control by residual spraying reinforced by short-term chemoprophylaxis.

BY Major M. A. C. DOWLING, M.R.C.S., D.P.H., D.T.M.&H. Royal Army Medical Corps AND R. D. HUGHES, Ph.D., B.Se. Formerly Lieutenant, Royal Army Medical Corps INTRODUCTION FOLLOWING the occurrence of a number of cases of malaria in naval personnel who had been ashore at Pulau Tioman, a survey of the island was carried out on 29th June, 1955, on behalf of the Royal Navy and with the consent of the...

Changes in Grape Maturity Induced by Spraying Ethanol

Three different ethanol solutions were sprayed onto Cabernet Sauvignon (Vitis vinifera L.) clusters during the ripening period: 2.5, 5 and 10% by volume in water. Controls were sprayed with water alone. Three different times of spraying were also tested: 8, 10 and 13 weeks post-flowering. One of the observed changes was a lower titratable acidity in grape samples at harvest, when the clusters w...

Spraying color Hilbert 1

What is color? Of course, examples of colorful objects are not hard to come by (Fig. 1 provides numerous examples), so the question itself is slightly puzzling, suggesting that some confusion needs to be cleared up or ignorance enlightened. But how could anyone (who isn't blind or totally lacking in color vision) possibly be confused about what color is? After all, if we learn anything about th...
