The magnitude of the stress introduced into a long slender bar t>y velocity impact depends only upon the conditions of impact. Thus, buckling of this bar under impact loading can only take place after the compressive stress wave has propagated over a critical'' length of the bar. Column behavior under impact is studie…

The line profile of the h th order reflection from a set of lattice planes is known to be given by a Fourier series with coefficients A(h,m)=N(m)J(h,m) . The function N(m) depends on the particle shapes and sizes, and J(h,m) depends on the state of strain Neither can be completely determined from the experimental Four…
An investigation of the uranium‐carbon system has been made and a constitutional diagram drawn on the basis of melting point, x‐ray, and metallographic data. Three carbides of uranium have been detected and identified: , , and . No compounds have been found containing a carbon content higher than that of . and are com…
The rate of thermal decomposition of nitric oxide has been measured in a quartz vessel from 872 to 1275°K. The reaction follows a second-order rate law over the range of temperatures studied. Variations in the surface-to-volume ratio of the reaction vessel indicate the predominance of a heterogeneous mechanism at temp…
Because of the experimental difficulties imposed by the prominence of delayed elastic and viscous effects, little investigation has been made of the instantaneous elastic modulus of soda‐lime‐silica glasses above approximately 500°C. The method described in this paper provides a means of measuring the Young's modulus…

The distribution of the electrical potential inside an electrolytic solution is calculated for typical cases of cathodic protection with the aid of an auxiliary metal to be sacrificed. These calculations are used to work out equations and diagrams which permit prediction of the maximum extension of metallic surfaces f…

With the aid of an identity it is shown that relationships between signs of structure factors for centre-symmetrical crystals can be obtained even when the Haxker-Kasper inequality considerations yield no useful information.. It is shown that a structure determination can be formulated as a self-consistency problem wi…
Measured nuclear quadrupole effects in solids are discussed, compared with nuclear quadrupole coupling in gases, and correlated to some extent with molecular structure in the solid state. The iodine crystal affords a good example of intermolecular interactions in the solid state. In this crystal, nuclear quadrupole ef…

THE CHEMICAL COMPOSITION, PHYSICAL PROPERTIES AND PRINCIPLES OF APPLICATION OF GLASS BEADS ARE REVIEWED. ALL THE PROPERTIES OF GLASS WHICH SIGNIFICANTLY AFFECT BEAD REFLECTORIZATION ARE DIRECTLY RELATED TO COMPOSITION. CHEMICAL DURABILITY AND SERVICEABILITY ARE NOT SYNONYMOUS TERMS IN DEFINING THE QUALITIES OF GLASS B…
