Generation degree

We consider first binary schemes primal and dual need not be distinguished. If the symbol has d+ 1 factors of (1 + z)j2 then

These are the support, the generation degree and the interpolating degree. 

Similarly for higher derivatives up to the generating degree of the scheme. 

The behavior of NH- and N-vinylpyrroles in the reactions with electrophiles is defined by the competition of several nucleophilic centers, namely, a- and p-positions of the pyrrole ring, nitrogen atom, and, in the case of N-vinylpyrrole, p-carbon atom of the vinyl group. In this line, the issues of peculiarities of pyrroles and N-vinylpyrroles behavior in acidic media, possibilities and routes of pyrrolium and N-pyrrolium ions generation, degrees of their stability, chemical properties, electronic and conformational structure, and synthetic potential represent urgent challenge. 

Chemical composition does not generally come into play, except for the case where it is necessary to establish maximum specifications for undesirable compounds such as sulfur, nitrogen, and metals, or even more unusually, certain compounds or families of compounds such as benzene in premium gasolines. By tradition, the refiner supposedly possesses numerous degrees of freedom to generate products for which the properties but not the composition are specified. 

Therefore, in the cases of both additives, the kinetic law for the catalysis will assume a linear form when the concentration of the added species, or, in the case of sulphuric acid, the nitronium ion generated by its action, is comparable with the concentration of the species already present. This effect was observed to occur when the concentration of additive was about o-2 mol 1, a value in fair agreement with the estimated degree of dissociation of nitric acid ( 2.2.1). 

The degree to which allylic radicals are stabilized by delocalization of the unpaired electron causes reactions that generate them to proceed more readily than those that give simple alkyl radicals Compare for example the bond dissociation energies of the pri mary C—H bonds of propane and propene... 

The iodine number of fats and oils provides a quantitative measurement of the degree of unsaturation. A solution containing a 100% excess of IGl is added to the sample, reacting across the double-bonded sites of unsaturation. The excess IGl is converted to I2 by adding KI. The resulting I2 is reacted with a known excess of Na2S203. To complete the analysis the excess 8203 is back titrated with coulometrically generated I2.
