This selection process is based on simple thermodynamic principles, prior experience, and empirical force field calculations (18,19,I9a). The methodology has evolved to include consideration of unsaturated and aromatic systems and we suggest its use not only in conjunction with but also in place of experimental determinations. The stabilomers for tricyclic, tetracyclic and pentacyclic Cg-C2o s are predicted for cases where no experimental information is yet available. This computational method also allows the quantitative estimation of AAHf regardless of its magnitude. Finally, saturated, unsaturated and aromatic hydrocarbons can all be compared. 

Quantitative estimation of the effective material properties and constitutive closure relations is of paramount importance for high-fidelity macroscopic, voliune-averaged computational models deployed in the PEFC performance simulations. The microstractural heterogeneity (e g. morphology, pore connectivity, pore size distribution, anisotropy) inherent in the PEFC components (CL, GDL, MPL) poses a profound impact on the effective transport properties, such as effective diffusivity in the unsaturated and partially saturated (e g. pore blockage by liquid water)... 

The use of sodium borohydride with palladium chloride has been described for the reduction of olefins in excellent yields. The method is quite reliable and it has been applied as an analytical technique for the quantitative estimation of the degree of unsaturation of a compound or of a mixture. 

Vapor pressure The vapor pressure of a substance is defined as the pressure exerted by the vapor (gas) of a substance when it is under equihbrium conditions. It provides a semi-quantitative rate at which it will volatilize from soil and/or water. The vapor pressure of a substance is a required input parameter for calculating the air-water partition coefficient (see Henry s law constant), which in turn is used to estimate the volatilization rate of compounds from groundwater to the unsaturated zone and from surface waterbodies to the atmosphere.
