TSs has little use as pure resin, but requires addition of other chemicals to render them processable. For RPs, the compounds usually comprise a resin system [with curing agents (catalysts), hardeners, inhibitors, plasticizers] and fillers and/or reinforcement. The resin system provides the binder, to a large extent dictating the cost, properties, dimensional stability, heat, chemical resistance, and basic flammability. The reinfisrce-ment influences primarily the effect of tensile strength and toughness. 

In molecular mechanics and molecular dynamics studies of proteins, assig-ment of standard, non-dynamical ionization states of protein titratable groups is a common practice. This assumption seems to be well justified because proton exchange times between protein and solution usually far exceed the time range of the MD simulations. We investigated to what extent the assumed protonation state of a protein influences its molecular dynamics trajectory, and how often our titration algorithm predicted ionization states identical to those imposed on the groups, when applied to a set of structures derived from a molecular dynamics trajectory [34]. As a model we took the bovine... 

Consider whether there is some process method to protect source/environ-ment. In that case, return to process description. For example, if thermal insulation is needed to reduce loads, consider what influence that has on the process itself (Insulation may, e.g., lead to a need to change material of equipment). 

In most cases, fluonnated substituents, when not directly placed at the reaction center, do not influence much the rearrangement routes [7] Favorskn rearrange ment of a substrate bearing a tnfluoromethyl group proceeds as expected [46] (equation 10)... 

The positive intercepts in Figure 7 show that post-gel(inelastic) loop formation is influenced by the same factors as pre-gel intramolecular reaction but is not determined solely by them. The important conclusion is that imperfections still occur in the limit of infinite reactant molar masses or very stiff chains (vb - ). They are a demonstration of a law-of-mass-action effect. Because they are intercepts in the limit vb - >, spatial correlations between reacting groups are absent and random reaction occurs. Intramolecular reaction occurs post-gel simply because of the unlimited number of groups per molecule in the gel fraction. The present values of p , (0.06 for f=3 and 0.03 for f=4 are derived from modulus measure- ments, assuming two junction points per lost per inelastic loop in f=3 networks and one junction point lost per loop in f=4 networks. 

The cartridge life, which is estimated at 2-4 weeks, is strongly influenced by the amount of suspended solids in the water. It is reported that oil alone will not plug the cartridge. If the cartridge life is too short, a pretreal-ment system is necessary. 

The same considerations should also apply for long drains without fixed ends. In this case all conformations are accessible eventually, but, for times whidi are small compared to those required for a complete rearrar ment of conformation, the definiticm of mesh size and comments about its influence on the accessible local conformations should still be valid. 

How is the efficiency influenced by the BGE Peak I broadening is the result of different processes in CZE I occurring during migration [in addition, extracolumn effects contribute to peak width (e.g., that stemming from the width and shape of the injection zone, or the -f. aperture of the detector cell)]. If the system behaves I linearly, the individual peak variances (the second mo-9 ments), o j, are additive according to a... 

The balance of electrostatic and delocalization interactions in an isolated molecule may be perturbed by the influence of the solvent. In calculations based on Eq. 7, the analysis of solvation-energy terms suggested that the electrostatic contribution stabilizing the ap orientation of the acetal s ment is the conformationally dominant term. For example, in 2-methoxyoxane, the difference in energy of the (ap, ap) and (ap, sc) conformers in water, compared to that in the isolated molecule, caused by solute-solvent electrostatic interactions alone, amounts to 4 kJ.mor. Accordingly, the inter-and intra-molecular, electrostatic interactions operate in reverse directions in acetals. Whereas the intramolecular, electrostatic interactions are responsible, together with delocalization interactions, for the aiq)earance of the anomeric, reverse anomeric, and exo-anomeric effects, the solute-solvent electrostatic interactions lessen their im nitude, and may even cancel them. Of course, the solvent may also influence the electron distribution and energy of MO s in a molecule. In this way, the orbital interactions of lone-pairs and delocalization contributions to the anomeric effect may be scaled by the solvent, but this mechanism of the environmental effect is, in most cases, of only minor importance.

The major features of a determination carried out on an automatic seg-mented-flow analyser, namely precision and rapidity, are highly influenced by technical factors such as the extent of carry-over and mixing of reactants, the time during which the reacting plug remains in the system, etc. Below is a detailed discussion of a series of concepts key to the performance of this type of analyser and hence to the results they provide. 

Sample sheets of 100 x 50 x 4 millimeter were prepared with the wet deposition technique. Two rectangular TMA samples and one circular TMA sample were machined from these sheets. The rectangular samples, 10 x 7 x 4 mm, were taken in the length (X) direction and in the width (Y) direction of the sample sheet. The circular sample, diameter 5 mm, was used to measure the l.e.c. in the Z direction. The samples, placed in a TMA 7, were measured from -20°C to 120°C with a heating rate of 2°C/minute. Subsequently, the sample was cooled with the same rate and heated again for the real measuring scan. The first heating scan was ment to remove the frozen-in stresses which influence the thermal expansion behaviour (see 3.1.2).
