It is important to recall, that the reaction takes place on the gronnd-state surface. Clearly, at the same nuclear configuration, the other combination... 

Other combinations of upper- and lower-convected time derivatives of the stress tensor are also used to construct constitutive equations for viscoelastic fluids. For example, Johnson and Segalman (1977) have proposed the following equation...

Electrical Properties. CeUular polymers have two important electrical appHcations (22). One takes advantage of the combination of inherent toughness and moisture resistance of polymers along with the decreased dielectric constant and dissipation factor of the foamed state to use ceUular polymers as electrical-wire insulation (97). The other combines the low dissipation factor and the rigidity of plastic foams in the constmction of radar domes. Polyurethane foams have been used as high voltage electrical insulation (213).

Covers for the battery designs in Figures 1 and 2 are typically molded from materials identical to that of the respective case, and vent plugs are frequentiy made of molded polypropylene. Other combinations are possible, eg, containers molded of polyethylene or polypropylene may be mated with covers of high impact mbber for use in industrial batteries. After the cover is fitted over the terminal post, it is sealed onto the case. The cover is heat bonded to the case, if it is plastic it is sealed with an epoxy resin or other adhesive, if it is vulcanized mbber. Vent caps are usually inserted into the cover s acid fiU holes to faciHtate water addition and safety vent gasses, except for nonaccessible maintenance-free or recombinant batteries. In nonaccessible batteries, the vent is fabricated as part of the cover. 

Scheme 6 shows representative members of these three groups. Other combinations are possible and the design of an appropriate bielectrophile for use as a versatile synthon presents a considerable synthetic challenge, as by virtue of the structural entities involved they are extremely reactive.

Saturable reactors, which are adjustable by a small dc signal, have also been used for both primary (stator) and secondary (rotor) control. In the primary they control motor voltage and therefore torque. In combination with fixed secondary resistors and feedback from a tachometer, this system can be used for precise speed and torque control of cranes, hoists, etc. Even reversing can be accomplished by using two saturable reactors in each of two (of three) phases. Other combinations of fixed or saturable reac tors in the primaiy and/or secondaiy, all combined with secondary resistors, provide a wide range of capabiUties and flexibihty for the wound-rotor motor. 

Equation (A. 15) was derived with the rate of decay dependent upon F and li. We could just as well have derived expressions for D,a in terms of F and p, or F and a, or other combinations. Two of these expressions are listed... 

A more rare form of driver is the steam cylinder. Most arrangements combine the steam driver and compressor on the same frame with the steam cylinder opposite the compressor cylinder. Each cylinder s connecting rod is connected to a common throw on the crankshaft. A flywheel is used to provide inertia. For air service, the units are built as single- and two-stage units, with other combinations available for process service. 

Compressors built to the API standard are required to have equal thrust capability in both directions that is, the bearing is to be symmetrically constructed. However, the thrust bearings can be combined using various numbers of pads on each side, or a tapered land can be combined with the multiple-segment design. Other combinations of the four thrust bear ings discussed are found in certain isolated applications. 

The model-dependent aspect of ellipsometric analysis makes it a difficult technique. Several different models fit to one set of data may produce equivalendy low MSEs. The user must integrate and evaluate all available information about the sample to develop a physically realistic model. Another problem in applying ellip-sometry is determining when the parameters of the model are mathematically correlated for example, a thicker film but lower index of refraaion might give the same MSE as some other combinations of index and thickness. That is, the answer is not always unique. 

The nomenclature used in AES has also been mentioned in Sect. 2.1.1. The Auger transition in which initial ionization occurs in level X, followed by the filling of X by an electron from Y and ejection of an electron from Z, would therefore be labeled XYZ. In this rather restricted scheme, one would thus find in the KLL series the six possible transitions KLiLi, KL1L2, KL1L3, KL2L2, KL2L3, and KL3L3. Other combinations could be written for other series such as the LMM, MNN, etc. 

The remaining AOs are the four H 1, two C 1, and four C 2p orbitals. All lie in the molecular plane. Only two combinations of the C 2s and H U orbitals meet the molecular symmetry requirements. One of these, nearest-neighbor atoms. No other combination corresponds to the symmetry of the ethylene molecule.

In exposures by inhalation of airborne materials, the dose is the concentration multiplied by the time (CT), and is roughly a constant for any given material and specified effect. The CT value can be used to provide a rough approximation of other combinations of concentration and time which would have about the same effect. Although this concept must be used very cautiously and cannot be applied at extreme conditions of either concentration or time, it is most important in setting limits for airborne contaminants and physical agents in respect to environmental exposures. The worker is exposed for various periods of time, day after day, to the... 

For the conditions given, = 13.5 MN/m which is less than the permitted maximum of 15 MN/m and so the chosen dimensions are acceptable. Note that the stress is independent of the width, b. Fig. 2.24 gives a set of design curves for the situation considered so that it may be seen that other combinations of L, d and b could be chosen to meet the design specification. For example, L — 22 mm, d = 2.5 mm and b — 2 mm gives an insertion force of 4 N and a maximum stress of 14 MN/m which is again acceptable. 

Many other combinations exist but will not be described here. In small cabins, for storage or work, it is possible to supply and exhaust air in a controlled way to have a defined climate. There are also special sluices, where air is used to rinse the clothes from settled contaminants before a person proceeds to the next, cleaner room. In this case, very high air velocities are used, which could cause discomfort to the person. The residence time for the person usually is less than a couple of minutes and the main objective is to clean the clothes (and sometimes the skin) and therefore the high velocities do not matter. 

Exhibit 5-2 shows three sample project installation strategies. Each example shows one possible implementation strategy. Variations on these will almost certainly be required to meet local circumstances. Example 1 envisages shared responsibility for the project with local staff. Example 2 shows local staff taking the lead and Example 3 shows minimal involvement of local staff. Other combinations of responsibilities and the use of other resources are also possible. Constant in all the examples is the development of management processes ahead of programs and elements, and the provision of local training before installation starts.

Table 10-7 shows suggested tie rod count and diameter for various sizes of heat exchangers, as recommended by TEMA . Other combinations of tie rod number and diameter with equivalent metal area are permissible however, no fewer than four tie rods, and no diameter less than /g-in., should be used. Any baffle segment requires a minimum of three points of support.

Phthalic anhydride, a polyol, and an unsaturated fatty acid are usually copolymerized to unsaturated polyesters for coating purposes. Many other combinations in variable ratios are possible for preparing these resins. The 1998 U.S. production of polyesters was approximately 1.7 billion pounds.
