Routine results of an algorithm for managing the production of blood components
Abstract Background and Objectives The variability in the number of donations together with a growing demand for platelet concentrates and plasma‐derived medicines make us seek solutions aimed at optimizing the processing of blood. Some mathematical models to improve efficiencies in blood banking have been published.

Estimating biocontrol agent spread: A case study using introduced dung beetles
The average rate of spread varied between species from a high of ca. 79 km/year (E. intermedius) to a low of 28 km/year (Ont. taurus). The area of spread varied between 99,175 km2 and 34,175 km2, and abundance varied from 88,100 beetles/km2 to 4,189 beetles/km2.
