A distinction is made between the surface Helmholtz free energy F , and the surface tension γ. The surface energy is the work necessary to form unit area of surface by a process of division: the surface tension is the tangential stress (force per unit length) in the surface layer; this stress must be balanced either b…
The energies and motions of grain boundaries between two crystallites are investigated theoretically using the dislocation model of grain boundaries. Quantitative predictions made for simple boundaries for cases in which the plane of the boundary contains the axis of relative rotation of the grains appear to agree wit…
This significant volume is a progress report of the research work on the most efficient and practical methods of protecting man against the extremes of external temperatures such as encountered in the polar regions, in equatorial deserts and at high altitudes in the air. This work, by competent biologists, medical doc…
Abstract A graphical method for interpreting refraction profiles is presented by means of a complete solution of a numerical example.
