Figure 10. Autoionization electron spectra due to electron-He collisions at 60.2 eV, obtained at different detection angles. The solid curves show the best fits obtained using the shake-down model and assuming that autoionizing transitions from (Is S and (2s2p) P do not interfere with each other but only with their respective parts of the direct ionization. (From Ref. 96.)...

The same culture conditions are used for bacterial expression of rCRALBP with the pET 3a- or pET-19b plasmids. The following procedure is used for growing a 1.2-L culture in a 2.8-L Fembach flask and can be scaled up or down as needed. Typically six 1.2-L cultures are grown simultaneously in a controlled environment incubator shaker (model G25, New Brunswick Scientific) at 37°C with vigorous shaking. 

This model produces the powerEil result that if customers vary in their taste for safety then for a given set of Erm preventive effort and prices, both Erms will have demand for their vertically differentiated product (Shaked and Sutton, 1982). In a free-entry competitive model, entry of new Erms occurs until prices are driven down to marginal cost. The nature of the marginal cost functions, the number of customers, and the distribution of their tastes will determine the socially-beneEcial equilibrium number of Erms, and hence levels of safety in the market.
