The specific conductivities of saturated solutions of calcium hydroxide have been measured from 0° to 130 °C. Special precautions were taken to eliminate errors due to impurities. The degree of dissociation and so called dissociation constants have been calculated for these solutions from 0° to 100 °C. These data have…

Abstract This paper is primarily concerned with the effect of size on the ordinary strength properties of materials. The use of models in stress analysis is described briefly. The effect of size in tension, fatigue, and impact tests is considered in detail. Possible explanations for departure from the law of similarit…
Abstract As a consequence of the work described the author arrives at the conclusion that in the deformation range from 0 to 270 per cent only one elastic constant is needed for a full mathematical description, and that this constant is the modulus of shear defined for infinitely small deformations. If models could be…

Because of the thermal energies of the electrons in a metal there can be no sharply defined maximum emission energy of photoelectrons, as was once supposed. On the basis of the Sommerfeld theory and the Fermi-Dirac statistics, expressions are derived for the form of the energy distribution and current voltage curves i…

It is shown that the ultraviolet absorption of NaCl, KCl and KI, which one may estimate from recent experimental work, is in agreement with the dispersion of these salts. With these assumed absorption curves, the dipole-dipole potential constant for the van der Waals attraction between negative ions can be calculated…

During the progress of studies made upon anemia in pregnancy (1, 2, 3, 4, 5, 6), it was observed that no matter how anemic the mothers, their infants were always born with a normal amount of hemoglobin and a normal red blood cell count. It shortly became apparent, however, that after several months these infants born…

The homogeneous gaseous decomposition of ethylene iodide has been studied in the temperature interval 205°—230°C. It is found that two simultaneous reactions occur to give the same final products, ethylene and iodine. One is a reaction catalyzed by iodine atoms, similar to that found to occur in solutions. The other i…

The dielectric constant and power factor of liquid sulphur were measured by a bridge method at four different audio-frequencies and over the temperature range 118°C to 350°C. The dielectric constant was found to be independent of frequency and equal to 3.520±0.010 at 118°C. A study of the polarization curve shows that…

Summary The lattice parameters of ten elements, each possessing cubic symmetry, were measured by a precision X-ray method. Four of the elements were spectroscopically pure and the others were of a high degree of purity. The lattice parameters at 18°C. were found to be as follows:—Au 4·0699±0·0003 Å. ; Pt 3·9158±0.0003…

Abstract Es wird das Gold‐Kupfersystem an einer Reihe dicht beieinanderliegender Legierungen verschiedener Konzentration im abgeschreckten und im getemperten Zustande untersucht, und zwar mit Hilfe des Verhältnisses der elektrischen Widerstände bei − 195 und − 252,4° C zu dem Widerstand bei 0° C. Die Resultate sind ta…
