Summary and Conclusions. Simple shear is by far the most important type of deformation in studies of viscoelastic bodies, because [for example] the absence of a volume change facilitates interpretation of the behavior in molecular terms (8).

The first step in catalysis is the formation of an enzyme-substrate complex. Substrates are bound to enzymes at active-site clefts from which water is largely excluded when the substrate is bound. The specificity of enzyme-substrate interactions arises mainly from hydrogen bonding, which is directional, and the shape of the active site, which rejects molecules that do not have a sufficiently complementary shape. The recognition of substrates by enzymes is accompanied by conformational changes at active sites, and such changes facilitate the formation of the transition state. 

Structural changes of starch and hydrogen starch granules on heating have been discussed. These changes facilitate the next stage of dextrinization, which is chemical in character. 

EXPLANATION OF CHANGE. To change the requirement in DOE 5480.30, NUCLEAR REACTOR SAFETY DESIGN CRITERIA, for EH concurrence with requested exemptions from the Order and update other EH responsibilities. These changes facilitate the Department s organizational transition necessitated by establishment of the NNSA. 

The electronic origin of the observed effect lies in the greater transfer of electron density from the catalytic metal center to the CO ligand oriented trans to the alkyne. This change facilitates the process where electron density is transferred from the vinyl ether to the alkyne, allowing the TS to benefit more from the trans CO acceptor ligand than the starting alkyne-Rh complex. 

The valine in position 67 of the j8-chain is replaced by glutamic acid in the Milwaukee variety of Hb M. The molecular changes facilitate the conversion of the ferrous iron to a ferric iron. 

Catalyst A substance which without itself undergoing any permanent chemical change facilitates or enables a reaction between other substances.
