The reactivity of the investigated diesel soot and model substances was positively correlated with their oxygen mass fraction and negatively correlated with their carbon mass fraction.
The kinetic study indicated that the degradation rate of the used model substances was first order and the calculated reaction constants were affected by the parameters studied.
By using the block co-polypeptide, aggregate formation and sustained-release behaviour of model substances were investigated.
The immobilized bovine trypsin was used as model substance, and was quantified according to its enzymatic reactivity (Puleo 1996; Tessmar et al. 2003).
To gain more insights into the mode of action as well as to evaluate the vulnerability of terminal dimethylated α- N-heterocyclic thiosemicarbazones to drug resistance mechanisms, a new cell model with acquired resistance against the model substance KP1089 was established (Fig. 1).
In this context, we believe that VPA is a good model substance to be addressed by a toxicogenomics approach.
The annulus substance was modeled as a hyperelastic material, and the nucleus pulposus was modeled as an incompressible substance because it displayed both solid and liquid viscoelastic charactereristics.
The bipyridyl herbicides share common toxic mechanisms [ 158, 159]; paraquat has been used as a model substance, but is no longer allowed in the EU.
The annulus ground substance was modeled based on an incompressible, hyperelastic, 2-parameter (C1, C2) Mooney-Rivlin formulation, and the nucleus pulposus was modeled as an incompressible fluid.
β-carotene was used as a poorly water-soluble model substance that is difficult to formulate with conventional solid dispersion formulations.
