The interaction between ions of the same sign is assumed to be a pure hard sphere repulsion for r < a. It follows from simple steric considerations that an exact solution will predict dimerization only if i < a/2, but polymerization may occur for o/2 < L = o. However, an approximate solution may not reveal the fiill extent of polymerization that occurs in a more accurate or exact theory. Cummings and Stell [ ] used the model to study chemical association of uncharged atoms. It is closely related to the model for adliesive hard spheres studied by Baxter [70].

Our interest is in the model of hard spheres with spherieally symmetrie assoeiative interaetions. This has been proposed and well studied by Cummings and Stell [25-27]. The model represents a two-eomponent mixture of hard sphere speeies, a and /5, with equal diameters, = [Pg.178]

The behavior of assoeiating fluid near the hard wall was extensively studied in the framework of the theory diseussed above. The model of Cummings and Stell was applied to relatively dense fluids at a high degree of dimerization [33,36]. Fig. 1 presents the density profiles ealeulated within the framework of the eombined PYl/EMSA theory (i.e., the density profiles were evaluated from the PY 1 equation, whereas the bulk direet eorrelation fune-tions follow from the EMSA equation) and HNCl/EMSA approximations [33]. The ealeulations were performed for L = 0.42[Pg.181]

Again, we consider the model of an associating fluid by Cummings and Stell [25-27]. The fluid is studied in contact with a hard wall Uq,(z) is given by Eq. (41). In this case Eq. (16) becomes [85,86]... 

In 1878 Hertz enrolled at the University of Berlin to study under Hermann von Helmholtz, the leading German physicist of the time. He obtained his degree magna cum laude in 1880 with a theoretical dissertation on the electromagnetic induction of currents in... 

Stock was born in Danzig, Poland, and his aptitude for science was displayed early in his boyhood collections of salamanders, butterflies, and plants. He studied at the University of Berlin where the chemistry facilities of the day were so limited that this brilliant experimentalist-to-be had to wait till liis third semester to approach a laboratory bench. He received the Ph.D. at the University of Berlin in 1899, graduating magna cum laude. 

Statistical methods are often employed to determine the study sample size and optimize power. Outlining the methods for calculating sample size and power for clinical trials is beyond the scope of this chapter. Interested readers are referred to texts by Chow and Liu (1998), Hulley and Cummings (1988), and Shuster (1990) for specific information on sample size and power estimation methods.
