Heat release rates from the calibration run and the walls were made using Equations 1 to 13. The fire endurance results will be discussed in another paper. The tests were terminated shortly after structural failure or burnthrough of the wall assembly. The test termination times are given in Table II. 

Fig.3. G (co) and G"(co) for monodisperse linear polymers of PI, PB and PS. The curves have been shifted so that the plateau moduli and terminal times coincide. The dashed line indicates the Doi-Edwards prediction for G"((o) in the absence of path-length fluctuations...

The terminal time and viscosity are dominated, as we saw above, by the potential at complete retraction U jj(L). This is now given by 15/24(MyM j, in much closer agreement with experiments. The formula for the relaxation mod-... 

So dynamic dilution is vahd in linear polymers only for the case of extremely wide polydispersity in which the weight distribution is broader than that of a power-law with exponent -5/2. In particular we see that it is not valid for near-monodisperse linear polymers around their terminal time. 

A feature of theories for tree-like polymers is the disentanglement transition , which occurs when the tube dilation becomes faster than the arm-retraction within it. In fact this will happen even for simple star polymers, but very close to the terminal time itself when very little orientation remains in the polymers. In tree-like polymers, it is possible that several levels of molecule near the core are not effectively entangled, and instead relax via renormalised Rouse dynamics (in other words the criterion for dynamic dilution of Sect. 3.2.5 occurs before the topology of the tree becomes trivial). In extreme cases the cores may relax by Zimm dynamics, when the surroundings fail to screen even the hydro-dynamic interactions between the slowest sections of the molecules. 

The terminal time r after which the chain has left its original tube determines to a large extent the viscosity of the melt see Eq. 3.32). For times...

Some milestones have many trajectories that terminate too quickly. Their termination time was shorter than 200fs typically required for velocity de-correlation. We remove these milestones (say milestone i) and compute instead transitional trajectories from the nearby milestones / - 1 and / + 1. Moreover, in a few milestones termination is found primarily or only in one direction. In this case, we added an intermediate milestone in the direction that was difficult to sample aud repeated the calculation. For example, if the sampling between milestones i and i + 1 is difficult, we add a new milestone half the way between i and / + 1 (say i + 0.5) and compute the transition between i and i + 0.5, and between i + 0.5 and + 1. 

The end of the saccade is normally terminated by the cerebellum. In most saccades, the SC continues to fire even though the saccade has ended. At the termination time, the cerebellar vermis, operating through the Purkinje cells, inhibits the contralateral FN and stimulates the ipsilateral FN. Some of the stimulation of the ipsilateral LLBN and IBN is lost because of the inhibition of the contralateral FN.
