Transitional phenomena in α‐polyolefin melts
Abstract A first order transition was observed in the temperature range of about 210°C by dilatometric studies on both isotactic and atactic polypropylene and for isotactic poly (butene‐1) and poly (pentene‐1). No such transition was observed for polyethylene. It was found that the transition is not due to the measure…
Studies on Atmospheric Corrosion of Steels Related with Meteorological Factors in Japan (2nd Report)
The atmospheric corrosion rates of steel were measured in an industrial district (Kôtô-ku) of Tokyo, Japan.Analyzing correlations between the corrosion rates and meteorological factors and/or atmospheric pollution substance factors by means of statistical analysis method, a corrosion regression was obtained to describ…

Diffusion-Controlled Attack of Glass Surfaces by Molten Hydroxides
The attack of soda‐lime‐silica, alkali borosilicate, zirconia‐silica and alumina‐silica glasses by sodium hydroxide and potassium hydroxide melts at temperatures just above their melting points has been studied. Sodium hydroxide attack resulted in a frosty layer bound to the surface; potassium hydroxide left a clear s…
The Cellulose/Water Relationship
This paper is a condensed survey of the interactions between water and cellulose materials. It is introduced by some general remarks about the interaction of water with solids, with special attention to hydrogen bonds, solutions and gels, then about the chemical and physical properties of cellulose fibres. The main di…
Raman spectrum of ZnO
The Raman spectrum of ZnO single crystals has been studied at room and low temperatures. About fifteen Raman peaks have been observed between 50 and 1 200 cm-1. The infrared reflection and transmission [1] measurements have also been made in the region 250 cm-1 to 1 500 cm-1 . The wurtzite (C46υ) structure has nine op…

Electrical Resistivity and Thermoelectric Power of Stacking Faults in Gold
Abstract Pure gold wires are quenched from high temperatures into iced brine and the changes of electrical resistivity and thermoelectric power are measured simultaneously during isochronal annealing. Two recovery stages are found: the first one (at 50 °C) corresponds to vacancy clustering with the formation of stacki…
Fission-Product Release from Monogranular UC2 Particles
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
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.
Solid Solution in the GeTe-InTe System
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…
Kinetics of desulphurization of liquid iron-sulphur alloys by mixtures of hydrogen with helium and argon
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…
The Role of Melting and Vaporization in Hypervelocity Impact
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…
Effects of Irradiation in Austenitic Steels and Other High-Temperature Alloys
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…
Effect of nuclear radiation on the thermal conductivity of polyethylene
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…
Stair‐rod Dislocations and Extended Barriers in the Body‐centered Cubic Lattice
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…
