✦ Synopsis

A model presented in a previous paper by BILLARD et al. (1985) on the spread of drug addiction in a closed population is further examined aa a random walk process. The addiction process depends on the initial conditiom and the parameters of the procees. This paper considers the ultimate size of the drug addict population which is shown to satisfy a recurrence relation. A general expression for t$e distributionof the ultimate size of the pu,m-ber of drug addicta is derived; its expected size a180 presented. For given initial conditions and the values of the parameters, numerical values of the expected size of the ultimate number of addict population are-presented and they are compared with the corrqponding values for the deterministic model.

Empirical biomass spectra in which biomass is measured in logarithmically equal body size intervals are different from those measured in linearly equal size intervals. Moreover, the scales of body size used by different authors may differ, e.g., length, volume, equivalent-sphere diameter and body ma
