21. The programmer can also force constants and loop variables to single precision ( default is normally double ) to execute twice as many operations per instruction. 22. They should have taken control, even taken it early when they were driving the lane unchallenged, controlling the boards and forcing constant Missouri misses and turnovers. 23. The construction of new routes by the BAE, along with the growth of competing railway networks, forced constant adjustments to rail services to respond to changing demand. 24. Viral promoters are often used for constitutive expression in plasmids and in viral vectors because they normally force constant transcription in many cell lines and types reliably. 25. The resultant force constant found for a ligated carbonyl represents the same force constant for pi ligands if they replaced the CO ligand in the same complex. 26. The resultant force constant found for a ligated carbonyl represents the same force constant for pi ligands if they replaced the CO ligand in the same complex. 27. The zero-point energy differences between the two isotopic species, at least in most cases, diminish in the transition state, since the bond force constant decreases during bond breaking. 28. In addition to the functional form of each energy term, a useful energy function must be assigned parameters for force constants, van der Waals multipliers, and other constant terms. 29. Information about the orientation of each interaction with respect to the global coordinates system is considered within the Force constant matrix ( H ) and allows prediction of anisotropic motions. 30. :: I've seen versions of string theory in which the universe expands and collapses over and over, and each time the fundamental force constants and the allowable particles change randomly.
