Phase destructive events

Ti is the level depletion lifetime and T2 is the pure dephasing time associated with the phase destructive events (e.g., by phonons and intermolecular interactions). This point will be taken up in more detail in Chapter 7. Here we merely note that the pure dephasing time is temperature dependent. 

Attainment of the goal of balanced plutonium production and consumption and minimum inventory will require a number of decades. Paradoxically, achievement of the goal will be most important in the event that nuclear power is phased out, leaving large and increasingly accessible plutonium inventories in many countries if no provision for their destruction has been made. While the global abandonment of nuclear power is extremely... 

F. Consequently, the scattering amplitude, e, is a complex number whose amplitude reflects the scattering strength, and whose phase factor determines the constructive and destructive interference conditions for any particular value of Q. The diffraction intensities are proportional to the magnitude of the scattering amplitudes. Consequently the intensities do not depend upon an absolute phase, but instead on the relative phases for each scattering event. 

In our own studies on the effect of GSH on radiation injury in the mouse (as shown by histological changes in hemopoietic tissues), the degenerative phase appeared identical in the control and treated animals. It was therefore suggested that the accelerated recovery of the bone marrow and of splenic myelopoiesis in the GSH pretreated irradiated mice may be due to protection of a mechanism which controls orderly hemopoietic regeneration. A similar concept has been proposed by Cole et al. (51). Bacq et al. (38), on the basis of their studies on the protective effect of beta-mercaptoethyl-amine, have come to comparable conclusions. Bacq (52) has gone further and proposed that the humoral factor may be or is closely related to coenzyme A. Lastly, Forssberg (47) feels that a similar sequence of events occurs vith root tips protected by cysteine. The destruction was identical in both controls and cysteine-treated irradiated roots, but mitosis returned much earlier in the cysteine-treated plants. 

The event of a three phase open circuit at the feedthrough, cable or inside the alternator windings would result in the loss of load on the alternator. Since the Brayton TCA shaft speed is based on the torque balance between the alternator, turbine and compressor, the loss of load would lead to an acceleration of the rotor shaft until some mechanical failure occurred, or a new stable operating speed was reached. For a single phase open circuit on the alternator a similar acceleration to the point of stability or mechanical destruction would occur, but the rate of acceleration would be much slower.
