Dependence INDEX

Figure 5.13 shows that the luminometer index depends directly on the mono-aromatic and di-aromatic contents. For this reason, the specifications... 

For a number of reasons, using saturation indices as measures of the mineral masses to be formed as a fluid approaches equilibrium is a futile (if commonly undertaken) exercise. First, a mineral s saturation index depends on the choice of its formula unit. If we were to write the formula for quartz as Si2C>4 instead of Si02, we would double its saturation index. Large formula units have been chosen for many of the clay and zeolite minerals listed in the llnl database, and this explains why these minerals appear frequently at the top of the supersaturation list. 

Vertzoni et al. (30) recently clarified the applicability of the similarity factor, the difference factor, and the Rescigno index in the comparison of cumulative data sets. Although all these indices should be used with caution (because inclusion of too many data points in the plateau region will lead to the outcome that the profiles are more similar and because the cutoff time per percentage dissolved is empirically chosen and not based on theory), all can be useful for comparing two cumulative data sets. When the measurement error is low, i.e., the data have low variability, mean profiles can be used and any one of these indices could be used. Selection depends on the nature of the difference one wishes to estimate and the existence of a reference data set. When data are more variable, index evaluation must be done on a confidence interval basis and selection of the appropriate index, depends on the number of the replications per data set in addition to the type of difference one wishes to estimate. When a large number of replications per data set are available (e.g., 12), construction of nonparametric or bootstrap confidence intervals of the similarity factor appears to be the most reliable of the three methods, provided that the plateau level is 100. With a restricted number of replications per data set (e.g., three), any of the three indices can be used, provided either non-parametric or bootstrap confidence intervals are determined (30). 

The temperature index is the maximum temperature that causes a 50% decay of the studied characteristics in the very long term. It is derived from long-term oven-ageing test runs. The UL Temperature Index depends on ... 

Were it not for dispersion—the refractive index depends upon wavelength— the aesthetic appeal of rainbows would be greatly diminished. Indeed, the word rainbow used in everyday speech evokes images of a profusion of colors—the colors of the rainbow—rather than just an intensely bright arc in the sky. If we take m = 1.343 as the refractive index of violet light (X — 0.4 jam) and m = 1.331 as the refractive index of red light (X = 0.65 jam) (Irvine and Pollack, 1968), then the angular widths of the primary and secondary rainbows are about 1.7° and 3.1°, respectively. 

Use of the differential refractometer detector is applicable to all polymers having refractive indices different from that of the solvent. However, a correction must be made if the polymer refractive index depends on molecular size, such as at very low molecular weights. 

The first point to be made is that in a crystal the refractive index depends not on the direction in which the electromagnetic waves are travelling but on the direction of the electrical disturbances transverse to the line of travel—the vibration direction . We have to consider the shape of the graph connecting refractive index with vibration direction for each crystal system, and the methods available for measuring the refractive indices of crystals in different vibration directions. 

No carbon was recorded for the D-treated film. The O/Si composition ratio was found to be 2.08 and is attributed to the extent of condensation as the organic phase has been removed completely. Based on the amount of Si for sample D and assuming a density of 2.3 g cm3 for amorphous SiC>2, the top layer would correspond to a thickness of 154 nm, if a dense layer is assumed. As the actual layer thickness is 458 nm, this would imply a porosity of 66%. Here a considerable discrepancy with the porosity obtained from ellipsometry is evident. In this respect it should be noted that the RBS measurement was done more to the edge of the sample than ellisometry, where the thickness is smaller than in the centre. Further, the refractive index determined with ellipsometry is very accurate. However, the relation of porosity with refractive index depends on the model used.

A polymerization that provides a transition into a discussion of gelation is the condensation of an excess of A-B with a small amount of an /-functional monomer, R-A/, that contains / equivalent functional groups of Type A, but no functional groups of Type B.[3 Linear chains are obtained when / is 1 or 2, but multichain condensation polymers are produced when/>2. At high conversion the polydispersity index depends only on/. 

The anisotropy itself may be linear or circular, or a combination of both. In linear anisotropy the refractive index depends on the direction of polarised light. It is found in solid polymers under tension and in viscous polymeric liquids during flow (shear and elongation). The refractive index can also depend on the chirality of polarised light in this case one speaks of circular or elliptic anisotropy. Thus the so-called "optical activity" is circular birefringence its extinction analogue is circular dichroism. 

In the Wonderland model, a pathological scenario was identified of very low values of the human development index, dependent on extreme values of two of the 41 variables. In the experiment with 500 runs, only three runs exhibited this behavior fewer runs in the design or a less flexible approximation strategy may well have missed this feature. 

Most aerosol materials will vary in their refractive index depending on the wavelength of light used, their chemical composition, and, in some cases, their orientation with respect to the light source and receptor. Since complex indices of refraction are not well established for most materials (Deirmendjian, 1969), optical models of aerosols may contain errors because of the uncertainty of these values. 

We hate using expressions like it can be shown that, but we don t have room to explain everything. If you keep in mind that the refractive index is related to the phase shift as a result of combining die light scattered in the forward direction with the incident beam, then it makes physical sense that the refractive index depends on the polarizability.

The physical properties, such as melting points, specific heat, viscosity, density, and refractive index depend on the type of fatty acids present in the triglyceride and their location, chain length of fatty acids, number and location of cis and trans double bonds on the fatty acid chains as well as compatibility of the different triglycerides in the mixture and the type of crystal present. 

The shape of the v versus [S] curve can be expressed in terms of the ratio of substrate concentration required for any two fractions of for example, 0.9 and 0.1 Vm,x- This ratio, called the cooperativity index, depends on the value of n as shown below.

The Hosoya Z index depends on the molecular size as well as on branching and ring closure. It was also found to correlate well with the boiling point. 

Formula indexes are a great help in searching for compounds. If one cannot find a compound in the subject index, he can find it in a formula index, provided he knows its structure. However, even formula indexes depend on rules for arrangement both of the symbols of elements in the formulas and of the completed formulas themselves, and not all indexes are constructed alike.
