Dempster et al (1983) assumed that logit of the historical rates is normally distributed. Bayesian methods are applied to obtain a P-value of the posterior probability of a positive dose-response slope. The authors indicated that their Bayesian approach is asymptotically equiva- lent to the large sample test of Tarone.

The adsorption of Lutetium on the peat is studied under static conditions. The adsorption ratio and adsorption rate for Lutetium onto peat are so high that the surface complex reaction reaches equilibrium. The adsorption of Lutetium is not pH and ion strength dependent. The kinetic process of adsorption can be described by the Elovich equation excellently among five kinds of classical kinetic models, and the adsorption isotherm fits both the Langmuir equation and Freundlich equation very well by means of regression analyses.
