Keith Cushman correctly observes how the poem shifts from cityscape to "bitter pastoral" (22), but "valley" and "fat neglected chances" also hint at some primal forfeiture, the legacy of which is that we can know only the fugacity of a specious present.

Building on my reflections in "Il concetto del tempo nella Divina Commedia" (Fu Jen Studies 35), it emphasizes the different sensibility with which Petrarch perceives the flow of time in an era that--with the advent of the mechanical clock and new urban rhythms of work--was keenly aware of time's fugacity and the need for human control over it.
In this poster, the importance of working with the chemical potential instead of the logarithm of fugacity coefficient in the calculation of phase equilibria has been explored for a cubic equation of state (EOS) as well as for a complex EOS.
