In careful experiments by Dyke and his co-workers it has been observed that the field-emission currents from tungsten and barium-on-tungsten emitters were progressively reduced below that expected from the Fowler-Nordheim law as the field was increased. These effects were attributed to electron space charges in the ne…
A brief derivation of formulas for the transmittance of flat plates, uncoated and coated, is presented. Data showing the increased near infrared transmittance of seven flat samples resulting from quarter-wave coatings of MgF2 and LiF on their surfaces is presented. Five were coated to maximize transmittance for a wave…

At the 222-kev resonance in the reaction ${\mathrm{Mg}}^{24}(p, \ensuremath{\gamma}){\mathrm{Al}}^{25}$, a 2.05\ifmmode\pm\else\textpm\fi{}0.02-Mev gamma ray in cascade with one of 0.454\ifmmode\pm\else\textpm\fi{}0.005 Mev, and a 1.56\ifmmode\pm\else\textpm\fi{}0.03-Mev gamma ray in cascade with one of 0.97\ifmmode\p…
The soiling and crushing characteristics of nylon, Dacron, 2 Orlon, 3 Saran, Dynel, acetate, wool, and smooth viscose, as well as the 50/50 blends of the synthetics and wool with smooth viscose were studied in Axminster carpets. Soiling properties are shown to be related to the fiber surface smoothness and avail able…
