INDEX evolution

Molybdenum Oxide. Molybdenum compounds incorporated into flexible PVC not only increase flame resistance, but also decrease smoke evolution. In Table 10 the effect of molybdenum oxide on the oxygen index of a flexible PVC containing 50 parts of a plasticizer is compared with antimony oxide. Antimony oxide is the superior synergist for flame retardancy but has Httle or no effect on smoke evolution. However, combinations of molybdenum oxide and antimony oxide may be used to reduce the total inorganic flame-retardant additive package, and obtain improved flame resistance and reduced smoke. 

For an analytical treatment of Eq. (18) we make a mean-field approximation in layers, where the index i is now decomposed into the layer index k and lattice position j within the layer Si s /.. The mean-field approximation in the layer leads to the layer order parameter = (T. Its evolution is obtained from (18) as...

An accurate measure of the apparent causes of the evolution of pharmaceutical expenditure could be obtained by taking chain-linked Laspeyres price indexes for each therapeutic group with a suitable level of disaggregation. In this situation, ideally we would have monetary measures of willing-... 

One study on the evolution of Spanish public pharmaceutical expenditure21 concludes that spending on pharmaceuticals rose 264 per cent in real terms from 1980 to 1996. This figure can be broken down into a 39 per cent decrease in the relative price of medicines, a 10 per cent increase in the quantity and a variation of 442 per cent explained by a residual that reflects the effect of the introduction of new products and a shift in consumption. As we can see from these figures, we have no practical price index and no quantitative approximation to the breakdown of the increase in expenditure into price and quality. 

Lobato s work19 makes at least four contributions. First, it seeks to quantify the demand for pharmaceuticals and argues that those variables that are employed in an attempt to approximate physical consumption, such as the number of prescriptions or packages, are not useful because they sum heterogeneous units. Monetary valuation presents the problem (considered below) of what price indexes are to be applied as deflators when studying the evolution of demand and expenditure over time. 

Nonell and Borrell6 also study the evolution of public drug expenditure between 1986 and 1997 and break down its growth into five factors demography, coverage, index of prices actually paid for the products financed, number of prescriptions per insured person, and the real cost per prescription calculated as a remainder. They conclude that the dynamics of the average cost per prescription is the main driving force behind expenditure (p. 123). 

Fig. 6-5. The evolution of the lagoon s waters in response to oscillations in biological productivity. The results show the adjustment of the system from an initial composition equal to that of seawater. This figure shows isotope ratios, calcium concentration, the saturation index, and productivity.

Fig-3. Schematic representation of the Penn West Cardium C02 EOR project together with the time evolution of the calcite saturation index. The horizontal line in each SI figure represents an SI of 0. The maximum SI on each figure is 0.8 and the minimum is -0.4, with the exception of well 08-11 with a maximum SI of 0.4 and a minimum of-1.6. 

Electronic polarization of the environment. This effect is related to the square of the refractive index, n1 2 (dielectric constant at the frequency of light). Here the spectral shift occurs instantly (10 15 s), and its evolution with time is not observed by the kinetic spectroscopic methods. The protein molecule is a medium with a relatively high electronic polarization (n= 1.5 -s-1.6). 

Among these, iron is relatively easy to measure and serves as a reference, as a metallicity index, and thus as an indicator of the degree of evolution. Indeed, it is common practice in astronomy to treat the terms iron content (Fe/H) and metallicity (Z) as synonymous. Solar metallicity is denoted Zq.
