And Burning Man co-founder Larry Harvey has been fairly critical of the traditional art world, arguing that it increasingly resembles a "professional ghetto," where works are sold for ever higher prices as investments and are rationalized by an arcane academic discourse.
The magnitude of OH⋅⋅⋅F IMHBs and their strong dependence on the overall molecular conformational profile, fluorination motif, and alkyl substitution level, is rationalized by quantum chemical calculations.
The change of the oxidation state of nitrogen from a high value in NO or NO2 to a lower value in nitrile and amino groups of the deposit is rationalized by applying mechanistic concepts of organic chemistry, including the Beckmann rearrangement and fragmentation.
Lilian's hand-raising is "rationalized" by her beliefs, desires, and intentions, because these cause her hand-raising.
This is rationalized by a kinetic scheme coupling rapid conformational sampling and slow chemical reaction rates.
