The Time Decay Constants in Neutron Thermalization

Nuclear Science and Engineering, 1963
We examine herein the decay constants, λk which appear in the modal expansion of the neutron density in a study of the time-dependent thermalization of neutrons.

A Review of Thermal-Radiation Constants

Journal of Fluids Engineering, 1954
Abstract A survey of engineering literature and some of the recent textbooks in heat transfer indicates a lack of knowledge by the authors that the various radiation constants used are no longer valid. The various radiation constants, as reported in the CGS system of units by Birge (3), have been ignored, as well as the recent work of ...

The Thermal Time Constants of Dynamo-Electric Machines

Transactions of the American Institute of Electrical Engineers, 1925
Considering the thermal behavior of a dynamo-electric machine intended for continuous service, its acceptance tests require, at present, only a limiting temperature elevation under a continuous rated load. For the intelligent operation of a machine after it has been put in service, additional information is desirable concerning its thermal behavior ...

Thermal Constants and Structure of Tin Clusters

1990
The Knudsen effusion method coupled with high temperature mass spectroscopy was used in evaluating thermal constants for the gaseous Snn (n=4–7) molecules. The enthalpies for the following reaction was determined: Snn(g) = nSn(g) for n = 4–7. The resulting atomization energy, heats of formation and entropy are for the linear molecules:

Thermal constants of pyrophyllite and their change on heating

British Journal of Applied Physics, 1955
Results are given for the thermal conductivity, thermal diffusivity and specific heat of pyrophyllite before and after heating to temperatures up to 1200° C. Before heating, the conductivity in directions parallel to the bedding planes is about 0.01 cal cm/cm2 s °C (0.04 joule cm/cm2 s °C) and at right angles to these planes it is half this value.

Thermal desorption with small friction constant

Physics Letters A, 1978
Abstract The technique previously introduced by the author for the large friction constant regime is utilized to calculate the exact escape rate for thermal desorption with small friction constant using the equation derived by Kramers for slow diffusion in energy.

Some thermal constants of carbon dioxide.

1925
For many years, low temperature research has held a certain fascination for many workers. The results of investigation, however, have not been very plentiful, especially in the realm of latent heats of fusion. In reality there are very few substances whose latent heats of fusion and specific heats at low temperatures are accurately known. Regardless of
