Hudson Bay Company

Figure 1.2 shows the number of lynx furs turned in to the Hudson Bay Company from 1820 to 1920. Distinct oscillations are seen with a period of about nine years. No data were available on the rabbit population, so we cannot be certain that the oscillations are due to a predator-prey interaction. However, controlled experiments have been performed in the laboratory with paramecia (Paramecium aurelia) that eat the yeast Saccharomyces exiguns (Figure 1.3). Notice how the predator population lags behind the population changes in the prey.

Auckland Geddes grandfather had been the Hudson s Bay Company s official agent in Scotland. His second nephew, Anthony, was a member of the Governing Council of the Royal Institute of International Affairs in 1949, alongside Sir Mark Turner, Rio Tinto s current chairman.

FIG URE 7.2. Variation with time of the number of furs (in thousands) from hares and lynxes delivered to the Hudson s Bay Company [18]. (See color insert.)... 

An example from population dynamics is presented in Fig. 7.2 that shows the variation with time of the number of furs from hares and lynxes delivered to the Hudson s Bay Company [18]. The oscillatory populations of both species are obviously coupled to each other with a certain phase shift. There is a plausible explanation When the l5mxes find enough food (i.e., hares) then-population increases, while that of the hares decays as soon as the birth rate cannot compensate the growing loss anymore. When the supply of hares drops, the lynxes begin to starve and their population decreases, so the population of the hares recover again. An approximate mathematical description of this effect can be achieved in terms of two coupled, nonlinear ODEs (Lotka-Volterra model) [19] for the concentrations of hares, x, and lynxes, y, as presented in Fig. 7.3, together with the solution for properly chosen parameters a and )8.

The first commercial installation of the standard slag fuming furnace was at the Asarco, East Helena lead smelter in Montana in 1927, and this furnace design has subsequently been applied at a number of other major lead smelters. Copper smelter slags rich in zinc are also processed in conventional slag turners such as at Boliden s Ronnskar smelter in Sweden, and at the Hin Flon smelter of Hudson Bay Mining and Smelting Company.

World War I chemical weapons laboratories included the Bureau of Standards, the Geophysical Laboratory, and the Naval Research Laboratory located in Washington, DC. The Naval Research Laboratory also had a large chemical weapons site on the Chesapeake Bay. Experiments with CWM also occurred at the Dow Chemical Company of Midland, Michigan, Zinsser Company of Hastings-on-Hudson, New York, and a Trench Warfare Section at Cleveland, Ohio.
