Qan ratio of unity. This was one of the first determinations of a Qan ratio for electron molecule reactions. The ECD values of the excited-state electron affinity, Qlm, and A i and E agree with the swarm values. The low-temperature response of the ECD can be calculated from parameters measured in swarm experiments. 

Most studies of the influence of temperature stress on plant nitrogen metabolism have been concerned with low-temperature responses and in particular the possible relationship between soluble nitrogenous compounds and freezing tolerance.

The interpretation of the low-temperature response obtained on Yb samples is clearly still complex. In low-symmetry structures the dependence on crystallographic direction implies that the crystal-field interactions must be important, although bearing in mind the physics of cerium and uranium systems discussed in sect. 4, the effects of hybridization will have to be incorporated into any comparison between theory and the neutron results. 

Many features of the data may be conveniently discussed in terms of theoretical descriptions based on the Fermi-liquid model. We shall start by considering the shape of the low-temperature response, for which the analytic function given by Kuramoto and Miiller-Hartmann (1985) is useful. This is followed by a discussion of some more general aspects arising from a consideration of the Wilson ratio (Wilson 1975, Lustfeld and Bringer 1978).

Hydrodynamic problems in hydrotreaters evidence themselves in several possible ways. Poor contacting can cause low apparent activity even if the presulfiding was done correctly. The reactor can show low temperature response. Also, the bed can exhibit high pressure drop. Lastly, there can be unexpectedly high response of conversion to small flow rate changes. Interpretation of each of these diagnostics will be discussed below.
