A survey has been made of the very large body of literature now existing on the characteristics of fallout particles. An attempt is made to summarize in concise form the ranges of physical and radiochemical properties of particles which have been observed to result from devices detonated under various conditions. The…

The need for more adequate engineering data and a better theoretical understanding of sulfide cracking has led to a more thorough study of several variables involved in the sulfide cracking of carbon steel. Hardness, yield strength, stress and microstructure were the primary metallurgical variables studied; sulfide co…
Abstract Stress softening (Mullins effect) is observed in gum natural rubber vulcanizates. The magnitude of this softening is similar to that in carbon black‐filled vulcanizates. The amount of stress softening is slightly greater in vulcanizates cured to produce predominantly polysulfide crosslinks than in those conta…

In the polymerization of alpha-olefins with heterogeneous Ziegler-Natta catalysts, the polymer is formed directly as long fibrillar units with folder chains. It is proposed that the fibrils are formed by the crystallization of polymer chains growing from the active sites on the catalyst surface, a process which is lik…
Abstract The determination of the stresses produced by cavity collapse has been of interest since Rayleigh’s discussion of the problem. One theoretical calculation relating to this problem is the magnitude of the pressure pulse which is radiated when a spherical bubble collapses and rebounds in a liquid. A calculation…
Abstract When a liquid mass strikes a solid surface, compressible behaviour, giving rise to a sharp peak of pressure, may occur in the initial stages of the impact. The duration of the peak depends on the dimensions and impact velocity of the liquid mass, and also on the compressional wave velocity for the liquid. The…
Abstract Blade erosion in wet steam turbines is considered to be preceded by the collection of large water droplets on the blade concave surfaces; this is followed by steam breaking up the resulting water film at the stationary blade trailing edges into fairly coarse, slow-moving droplets, and culminates in their coll…
Abstract A study has been made of the deformation at high strain rates of solids under the impact of liquids. A method is described for projecting a short liquid jet against a solid surface at speeds up to 1200 m/s. The flow of the liquid and the deformation of the solid during impact have been examined by high speed…
Abstract Our object is to present a broad review of this subject as a branch of hydrodynamics, referring both to the well known ‘implosion’ mechanism first analysed by Lord Rayleigh and, more particularly, to the recently perceived possibility that effects of equally great violence, such as to damage solid boundaries,…
Abstract A general thermodynamical theory is developed for rods. An elastic rod, and special cases of the general theory which are closely related to the classical theories of rods and strings, are also discussed.
This investigation of the spin arrangement in a single crystal of MnO above the N\'eel temperature (${T}_{N}\ensuremath{\simeq}122$\ifmmode^\circ\else\textdegree\fi{}K) has shown that the magnetic neutron scattering in the vicinity of the (111) magnetic peak position consists of diffuse but distinct satellites. The pr…
Translational and librational motions of H2O molecules in a frequency region lying below 1000 cm−1 have been previously examined for various configurations using the inelastic scattering of low-energy neutrons (0.005 eV). In the present work, H2O motions are studied in cases where neither of the lone electron pairs on…
Absorption spectra have been obtained of gaseous NdBr3 and NdI3 in the range 4000–25 000 cm−1 between 1000° and 1200°C. Spectra of solid and liquid NdI3 near the melting point have also been measured. The most prominent feature of the gaseous spectra is a complex band located between 16 000–17 000 cm−1 with oscillator…
We have measured self-diffusion along widely spaced edge dislocations in nickel. A surface-accumulation counting technique was used. The dislocations were arranged to be perpendicular to the surface which was counted and were pure edge in character. The diffusion measurements were carried out in the temperature range…
A high-temperature cluster series is derived for the partition function of an order-disorder-type hydrogen-bonded ferroelectric crystal, taking into account a simplified interaction between protons as well as the overlap of the protonic wave functions between the two sites in a hydrogen bond. The zero-order result is…
