A More Appropriate Description

There is a more appropriate wording that can be used.

Acid rain is the popular term for a very complex environmental problem. Over the past 25 years, evidence has accumulated on changes in aquatic life and soil pH in Scandinavia, Canada, and the northeastern United States. Many believe that these changes are caused by acidic deposition traceable to pollutant acid precursors that result from the burning of fossil fuels. Acid rain is only one component of acidic deposition, a more appropriate description of this phenomenon. Acidic deposition is the combined total of wet and dry deposition, with wet acidic deposition being commonly referred to as acid rain. 

A convenient term for the rheological properties of an unvulcanised elastomer (see Rheology). It has been defined as the susceptibility to, and retentivity of deformation , and also the degree of flow which takes place under given conditions of temperature and pressure . The use of the term viscosity is a more appropriate description. Plasticity Retention Index... 

A polyhedron based on bicapped dodecahedron possibly exists in decacoordi-nated [Ce(NOs)5]2- anion, which has been isolated (275) as triphenylethylphos-phonium salt (C2/c). The bicapped dodecahedron is a more appropriate description for the polyhedron than the bicapped square antiprism. However, Al-Karaghouli and Wood 215) from aesthetic point of view preferred to call the geometry of the coordination polyhedron as being trigonal bipyramid. 

The reader will note that the title of this chapter includes a second term in addition to the more familiar term validation. True classic validation of the cleaning process is not always possible in certain pharmaceutical operations, and verification is a more appropriate description of the approach to cleaning. The application of this concept to research and development (R D) areas will be developed and discussed in this chapter. 

Calling Reaction 2.10 an insertion of CO into a metal-alkyl bond may be misleading. There is evidence to show that the alkyl group actually migrates to CO. A more appropriate description of a number of insertion reactions is migratory insertion. However, in the rest of this book, we will ignore this mechanistic distinction and simply call Reactions 2.8-2.11 as insertion reactions. 

In the opposite case of narrow exciton bands, when the interaction (15.15) leads to sticking together of excitons into pairs, triplets, and more numerous excitonic droplets , a more appropriate description is that in terms of excitons-paulions. The process of exciton coagulation can be described with the well-known methods of colloid statistics (21). We notice here that the size distribution of exciton droplets will depend on the exciton lifetime, bimolecular quenching... 

In Section 7-6 we described resonance formulas for molecules and polyatomic ions. Resonance is said to exist when two or more equivalent Lewis formulas can be written for the same species and a single such formula does not account for the properties of a substance. In molecular orbital terminology, a more appropriate description involves delocalization of electrons. The shapes of molecular orbitals for species in which electron delocalization occurs can be predicted by combining all the contributing atomic orbitals. 

Since the polymer can be synthesized to such a high purity, a more appropriate description for the space charge is that given by trapped charges, rather than ionized impurities. Traps may arise, e.g., from conformational defects of the organic semiconductors. It is then the density of the traps in the polymer... 

Qearly it is a crude simplification to characterize the effect of the environment by a single parameter a. A more appropriate description would be to assign a viscoelastic character to the environment. However, we proceed here using the simplest possible model. As we shall show later various experimental results indicate that this model is adequate for linear polymers with narrow distribution of molecular weight. Limitations of the model will be discussed later. 

These mechanisms notwithstanding, if the particles were significantly larger in size than the pores in the fabric, a sieving mechanism would be a more appropriate description. It may also be added that some particles fail to be captured by the fabric due to gravitational force. 

In the case of the Koch curve, we can state that the curve length increases with each step of iteration by a factor of 4/3. The final curve is, thus, of infinite length. Hence, length is not a meaningful parameter to describe this curve. A more appropriate description of the curve is the power law relationship between the number N of basic elements used in curve design and their size L. 

The supermolecular approximation provides a more appropriate description of specific solvation and reaction mechanisms, where solvent molecules are considered to be reagents. Successful apphcation of the supermolecular approach requires... 

As a mean force, the capillary force also includes the force that the pressure field exerts on the interface. Therefore, the effective force that is assigned to a particle is not just the net force felt by the particle itself but there is also this contribution from the interface surrounding it, so that a more appropriate description would be that of an effective particle comprising the true particle plus the neighboring interface. We discuss an example of this phenomenon in Section 2.3.I.2. 

When the temperature inaeases, the probability of charge carrier transfer to the nearest neighbor increases, in spite of the energy difference, as shown in Figure 5(b). In such a case a more appropriate description of charge transport is offered by the Miller-Abrahams model descrihed in Section 2.33.2.3.2.2.
