The kinetic theory of the nucleation of new phases, developed especially by Volmer, l by
Farkas, 2 by Kaischew and Stranski3 and by Becker and DOring4 indicates that under …

In this review, we discuss how, due to a variety of different interactions between laser
radiation and biological tissue, the laser has become an established instrument in most …

Parts I and II deal with the theory of crystal growth, parts III and IV with the form (on the
atomic scale) of a crystal surface in equilibrium with the vapour. In part I we calculate the rate …

The theory of a one-dimensional dislocation model is developed. Besides acting as a
pointer to developments of general dislocation theory, it has a variety of direct physical …

The equations derived in part I of this series for a one-dimensional dislocation model are
applied in this paper to the case of a monolayer on the surface of a crystalline substrate …

A general theory of curvature-elasticity in the molecularly uniaxial liquid crystals, similar to
that of Oseen, is established on a revised basis. The= are certain significant differences: in …

MicroRNAs (miRNAs) mediate post-transcriptional gene regulation through association with
Argonaute proteins (AGOs). Crystal structures of archaeal and bacterial homologues of …

It is shown that a dislocation whose Burgers vector exceeds a critical value, of the order of
magnitude 10A., is only in equilibrium with an empty tube at its core. This is not the case in …

Complex alloy structures, particularly those of transition metals, are considered as
determined by the geometrical requirements for sphere packing. A characteristic of the class …

A method is given for finding the equilibrium positions of a set of like dislocations in a
common slip-plane under the influence of a given applied stress. Their positions are given …
