Since 5 is a function of all the intermediate coordinates, a large scale optimization problem is to be expected. For illustration purposes consider a molecular system of 100 degrees of freedom. To account for 1000 time points we need to optimize 5 as a function of 100,000 independent variables ( ). As a result, the use of a large time step is not only a computational benefit but is also a necessity for the proposed approach. The use of a small time step to obtain a trajectory with accuracy comparable to that of Molecular Dynamics is not practical for systems with more than a few degrees of freedom. Fbr small time steps, ordinary solution of classical trajectories is the method of choice.

The fed bateh reaetor (FBR) is a reaetor where fresh nutrients are added to replaee those already used. The rate of the feed flow U may be variable, and there is no outlet flowrate from the fermenter. As a eonsequenee of feeding, the reaetor volume ehanges with respeet to time. Figure 11-22 illustrates a simple fed-bateh reaetor. The balanee equations are ... 

Other newer designs include the advanced, gas-cooled reactor (AGR), Canadian deuterium reactor (CANDUR), sodium-cooled reactor (SCR), sodium-heated reactor (SHR), and fast breeder reactor (FBR). These reactors employ either natural or enriched uranium fuels that may be modified in some way (e.g., graphite-moderated fuels). 

Electron microscopic study reveals an incalculably small space between nerve endings and the effector organ (eg, tlie muscle, cell, or gland) diat is innervated (or controlled) by a nerve fiber. Fbr a nerve impulse to be transmitted from die nerve ending (motor end plate) across die space to die effector organ, a neurohormone is needed.

The third law of thermodynamics establishes a starting point for entropies. At 0 K, any pure perfect crystal is completely constrained and has S = 0 J / K. At any higher temperature, the substance has a positive entropy that depends on the conditions. The molar entropies of many pure substances have been measured at standard thermodynamic conditions, P ° = 1 bar. The same thermodynamic tables that list standard enthalpies of formation usually also list standard molar entropies, designated S °, fbr T — 298 K. Table 14-2 lists representative values of S to give you an idea of the magnitudes of absolute entropies. Appendix D contains a more extensive list.
