Considering the complexity of PCB congener profiles in commercial mixtures, we developed a limited mixture of PCB congeners that could be studied both in vivo and in vitro.
In addition, this limited mixture exerted a TH-like action in vitro only when present as a mixture and not when present as individual parent congeners.
We now show that a limited mixture of only six PCB congeners can reduce serum TH levels at the same time that it increases the expression of a well-known TH-response gene, ME, in the liver; thus, this limited PCB mixture can recapitulate the effect of a complex technical mixture, A1254 (Gauger et al. 2004; Zoeller et al. 2000).
However, for ER-β1 and ER-β2 the effect ranges for the predictions are limited: mixture effects can be determined by the concentration addition model only when it is possible to determine for each mixture compound a reliable estimate of a concentration that would produce the same effect when applied on its own.

The analyses of glass transition temperature and cold crystallization temperature of PHB in the PHB/additive mixtures showed that these additives are miscible with PHB and act as plasticizers, though the miscibility is found in the limited mixtures with low additive content.
Convergence bounds are calculated only for limited Bayesian mixture class/prior distribution pairs (for example, uniform prior/Epanchinkov kernel) [107].
The results at the present are limited to mixtures corresponding to positive Markstein lengths, and to "two-dimensional turbulent flows".
Group interaction parameters in the new equation were regressed from a limited amount of mixture data.
The present study adds to the limited database of mixture fraction and scalar dissipation rate measurements within turbulent flames.
Even if limited to binary mixture assessments, recently improved mathematical models have been proposed to describe such deviations [ 7].
Initial attempts to extend the concept to redox arylations using β-naphthol as the model nucleophile met with limited success; a mixture of various products was typically isolated.
