TL;DR: In this article, the gross bulk and shear moduli of a composite material consisting of a suspension of grains or a compact of grains are derived from an analysis of the dilatation and bulk stress for average spherical grains when the composite as a whole is subjected to some small temperature change.

TL;DR: In this paper, the system of differential equations proposed by V. Volterra, desoribing the variation in time of the populations of interacting species in a biological association, admits a Liouville's theorem (when log n · log n is used as variables) and a universal integral of motion.

TL;DR: In this article, it is shown how the Volterra population dynamics, which underlies the statistical theory, can be based on a variational principle; how the dynamics can be generalized as regards both the behavior of total populations and migration phenomena; and how many directly observable data, such as amplitudes and frequencies of oscillation of a population, fit into the statistical model and can test it.

TL;DR: In this article, the authors studied the supplantation of one of two closely similar competing species by the other (Volterra-Lotka principle) as an example, according to Volterra's general theory of population dynamics, of the decay of a biological association of an odd number 2 n+1 of species into one with an even number 2n.

TL;DR: The proposal is to consider seriously as a first step in a general theory of ecology the scheme of population dynamics advanced by a great mathematician, Vit,o Volterra (1931), almost 30 years ago.
