Characteristics of UC, ZrC, and (ZrC) (UC) as Thermionic Emitters
(The American Institute of Physics, 1959-10)
Uranium carbide is found to have the property of high thermionic emission in the observed temperature range from 1400 to 1800°K. The parameters of the Richardson equation which can be used to fit the data are A=7.3×105 ...
Some Exact Solutions of the Navier‐Stokes and the Hydromagnetic Equations
(The American Institute of Physics, 1959-03)
Some exact, closed‐form solutions of the Navier‐Stokes equations for incompressible flow and of the hydromagnetic equations for high‐conductivity, incompressible flow are presented. They can be considered to be generalizations ...
Stagnation Point Fluctuations on a Body of Revolution
(The American Institute of Physics, 1959-11)
Method for the Analysis of Multicomponent Exponential Decay Curves
(The American Institute of Physics, 1959-10)
A frequently encountered problem in many branches of science involves the resolution of experimental data into a sum of independent exponential curves of the formf(t)=∑i=1nNiexp(−λit),in order to estimate the physically ...
Low-temperature heat capacities and thermodynamic properties of zinc ferrites--III : Effect of copper substitution
(Elsevier, 1959-07)
The heat capacities of annealed and quenched samples of Cu0.05Zn0.90Fe2.05O4 have been determined over the range 5-350[deg]K. The Neel temperature is the same as that previously reported for a similar lithium-substituted ...
Magnetic properties of polycrystalline materials
(Elsevier, 1959-12)
The variation of the magnetic Q with internal magnetization is discussed, using both the domain rotation and the domain-wall motion model of magnetization change. The variation of the reversible susceptibilities with ...
Technique for Measurement of Cross‐Spectral Density of Two Random Functions
(The American Institute of Physics, 1959-03)
The cross‐spectral density of two functions may be determined by using two selective filters which have identical impulse responses except for a relative phase difference which should be 0° and 90° for the measurement of ...
NMR Spectra of Normal and Deuterated Methylacetylenes
(The American Institute of Physics, 1959-11)
Heat Capacities and Thermodynamic Properties of the Pyrrhotites FeS and Fe0.877S from 5 to 350°K
(The American Institute of Physics, 1959-02)
Heat capacities were measured from 5 to 350°K for two pyrrhotites at the iron‐rich limit (Fe1.000S) and the sulfur‐rich limit (Fe0.877S) of the homogeneity range. The heat‐capacity curves follow the normal sigmoid shape ...
