The fission-product release of spherical monogranular UC2 particles is studied by postirradiation annealing of neutron-activated samples and by exposing samples to a steady rate of photofission. The release of the several fission products studied appears to follow the kinetics and temperature-dependence of an activate…

The equilibrium of oxygen in liquid iron with H2-H2O mixtures has been studied at 1550°C, 1607°C and 1663°C respectively.Effects of nickel, cobalt, tungsten, molybdenum, chromium and tin on the activity of oxygen in liquid iron have been studied at 1600°C.The data obtained are summarized as follows:1. H2+O=H2Olog K1[=…
Drilocephalobus congoensis n. g., n. sp. has an offset head, large cup-shaped amphids, a large excretory gland cell, reflexed prodelphic female gonad, pointed tail and the male has spicules and gubernaculum. It seems to be intermediate between the Cephalobidae and the Drilonematidae.
Standard x‐ray powder photograph techniques have been used to investigate the phases occurring in alloys of the section and also in some general alloys of the ternary systems Ge‐In‐Te which lie in the composition range bounded by . The conditions when the alloys are water quenched from the melt and when annealed to eq…
Iron-sulphur alloys which contained up to 3.5% sulphur were desulphurized at 1545C by gas mixtures which contained 2-100% hydrogen along with argon and/or helium as diluents. The rate of the reaction was measured by observing the rate of production of hydrogen sulphide. The results indicated that equilibrium between h…
Abstract : The memorandum discusses the thermodynamics associated with the flow processes in hypervelocity cratering. Qualitative, graphical arguments are presented to show that previously proposed thermal-impact theories, which postulate that the kinetic energy of impacting projectiles goes entirely into breaking of…
Neutron irradiation has an adverse effect on the tensile ductility of austenitic steels and a nickel-base alloy at test temperatures above about 600 C. n contrast to the fast-neutron-induced, low-temperature irradiation hardening and embrittlement of materials, the loss in ductility at elevated temperatures is a funct…
Abstract Thermal conductivity curves for the 0°C to 170°C temperature region are presented for six irradiated low density polyethylene samples (radiation doses from 0 to 3100 megarads) and one irradiated high density sample (120 megarad dose). In agreement with data in the literature for unirradiated polyethylene, the…
Abstract The interaction of glissile extended dislocations on intersecting {112} planes in the bodycentered cubic lattice is considered. It is found that, for each axis of intersection of two {112} planes except 〈111〉, stair‐rod dislocations of Burgers vectors 1/3 〈001〉, 1/3 〈002〉, and 1/6 〈113〉 can be formed. Formula…
Abstract A discussion of the relationship between theoretical principles of chemical similarity on one hand and empirically measurable similarity on the other suggests that specifically adsorbing silica gels represent an experimentally simple model for ‘bioisomorphism’, the similarity found in biological systems.
The analysis of typical e - aq scavengers such as oxygen, hydrogen peroxide, nitrous oxide, acetone, and thymine in the concentration range from 10 -8 to 10 -6 M is reported. These compounds react with e - aq with rate constants that vary from 4 x 10 9 M -1 sec. -1 for thymine to 1.9 x 10 10 M -1 sec. -1 for oxygen. H…
A new and relatively convenient procedure for obtaining kinetic parameters in the degradation of high polymers is described and the necessary experimental procedure is outlined. Results for the degradation of Teflon are compared with several previously reported methods and the agreement is found to be good. Some advan…
Abstract Für das neutrale Salz, dessen Eigenschaften mitgeteilt werden, konnte die Zusammensetzung Bi(NO 3 ) 3 · H 2 O gesichert werden. Das thermische Verhalten des Bi(NO 3 ) 3 · 5 H 2 O wurde mittels isobarem Abbau, Aufheizversuchen und Differentialthermoanalyse untersucht und die Zersetzungsprodukte mit Hilfe von c…

Nous avons mesuré les potentiels d’apparition des ions : M+, MI+, M2I+, l+, HI+, LiMI+, ainsi que Li3I2+ et Na3I2+, où M représente un métal alcalin.
On the segregation of a steel or alloy ingot, the effect of stirring during the process of solidification appears to be an important factor to clarify the segregation phenomenon. In the present investigation on Al-Cu alloy, stirring was carried out by means of the method hydro-dynamically known as Taylor’s vortex flow…

The thermal conductivities of sintered Al 2 O 3 and UO 2 were measured in the ranges 400° to 1700°C and 300° to 2100°C respectively. The conductivity values for Al 2 O 3 agreed with those reported previously at all temperatures investigated. The conductivity of UO, decreased with increasing temperature to a minimum of…
