Whereas the loss of the telephone face off brings to us a diminutive version of rejection, we, all of us I believe, have begun increasingly to experience a variation of the face off felt not only as diminutive rejection, but even more so in the form of feelings of isolation and experiences of unimportance, even loneliness.
The differences are largely due to the fact that some trials included systematic CMV prophylaxis while others did not, and because of variations in the incidence of rejection and the consequent requirement for increased immunosuppression.
Ironically, Darwin's major, scheduled "Magnum opus" with the tentative title Natural Selection never appeared in print, but the Extract published by the author in November 1859 in order to establish priority with respect to his theory of the "preservation of favourable variations and the rejection of injurious variations" became a best- and longseller [ 6].
In addition to the best feasible operating conditions, which are the original outcome, the framework also provides a controllability index involving all of the output variables (generalised integral absolute error, GIAE) and the expected variation of profit on disturbance rejection dynamics.
This preservation of favourable variations and the rejection of injurious variations, I call Natural Selection.
Although Darwin understood natural selection on a general basis, defining it as the "preservation of favourable variations, and the rejection of injurious variations" (1859), he did not know how it actually operated because genetics was unknown at the time.
Trends in the variation of solvent flux and catalyst rejection with variation of these parameters were identified.
The proposed cycle configurations have an outstanding adaptability and flexibility to respond to the variation of heat source and heat rejection temperatures by adjusting the compression ratio.
To avoid variations in the results caused by different onsets of rejection patterns and genotypic specific reactions, rejection classifications were established by analyzing histological sections done on the climax status of the developed POR.
Performance comparison of the different FO fuzzy PID controller structures has been done in terms of optimal set-point tracking, load disturbance rejection and minimal variation of manipulated variable or smaller actuator requirement etc.
