The thermal constants of setting concrete
Proceedings of the Physical Society, 1936The rise in temperature in a large mass of concrete during setting may be considerable, and the shrinkage stresses induced by the subsequent cooling may become large enough to cause cracking. It is, therefore, important to be able to calculate the rise of temperature likely to occur in such a mass.

Thermal dependence of the lattice constants of LaAgSb2
Journal of Alloys and Compounds, 2002The results of neutron diffraction measurements as a function of temperature are analyzed. An anomalous temperature dependence of the lattice constant c and some interatomic distances is observed. This result indicates a change in the interactions between the atoms, especially those near the lanthanum atom.

The Thermal Time Constants of Dynamo-Electric Machines
Transactions of the American Institute of Electrical Engineers, 1925Considering 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 aspects of constant rate transformation
Journal of Thermal Analysis, 1988A mathematical model for the conjugate formulation of the working conditions of the Q-derivatograph is created. There are no simplifying assumptions about the heat transfer processes for reacting active media and for their thermal interaction with the inert surroundings in this model. The energetic significance of the key components of the transfer and

Thermal Constants and Structure of Tin Clusters
1990The 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 desorption with small friction constant
Physics Letters A, 1978Abstract 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.
