444 CLINICALCHEMISTRY, Vol. 33, No. 3, 1987 used for “SuperSTAT” bedside testing, as suggested by Ng et al. (1), this temperature bias must be taken into consideration. For example, mixing a sample by rolling the container between the palms should be avoided because this also will affect the sample temperature. Finally, the influence of different control-sample temperatures on precision (e.g., ...

We consider the totally nonfree (TNF) action of a groups and the corresponding adjoint invariant (AD) measures on the lattices of the subgroups of the given group. The main result is the description of all adjoint-invariant and TNF-measures on the lattice of subgroups of the infinite symmetric group SN. The problem is closely related to the theory of characters and factor representations of gro...
