INDEX priming

The analysis of the contribution made by increased pharmaceutical spending to the growth in the per capita intensity of health resources suffers from major measurement problems that deprive available indicators of any value. Traditional pharmaceutical price indexes (such as the Laspeyres index, used to calculate the pharmaceutical component of the consumer price index) provide little relevant information in a market in which the introduction of therapeutic innovations is of prime importance the indexes show an apparent freeze, and sometimes even a steep drop (as in the Spanish case). However, the steady rise in the average price per prescription paints a very different picture. 

The primed or unprimed symbols refer to isotope fractions. The single stage separation factor for infinitesimal product removal (yi/zj 0), (rj)0, is given the symbol a . The i s index the stage number. Most often a is close to unity and it is convenient to define the isotope enrichment factor (the single stage enrichment factor), e, between the i th and (i + l) th stage... 

Inevitably, the zeolites with a Spaciousness Index between 2 and 16 have a higher Si/Al ratio than zeolites Y or ZSM-20. To separate the effects of the Si/Al ratio and the pore width, two dealuminated samples of zeolite Y, designated YDl and YD2, were tested which resembled in their Si/Al ratios the Beta and EU-1 sample, respectively. Table 1 gives the isomerization selectivities at 40 % conversion. While dealumination of zeolite Y brings about some improvement in selectivity, H-Beta is clearly superior to HYDl, and H-EU-1 is a much better catalyst than HYD2, which indicates that the pore width in the appropriate range is of prime importance. 

The absorption parameter, k, and the refractive index, n, were measured using variable angle spectrophotometric ellipsometry. The bottom antireflective coating of test solutions were spin coated onto primed silicon wafers and baked to get selected film thickness. The coated wafers were then measured using an ellipsometer to obtain and n values. 

The proper choice of a solvent for a particular application depends on several factors, among which its physical properties are of prime importance. The solvent should first of all be liquid under the temperature and pressure conditions at which it is employed. Its thermodynamic properties, such as the density and vapour pressure, and their temperature and pressure coefficients, as well as the heat capacity and surface tension, and transport properties, such as viscosity, diffusion coefficient, and thermal conductivity also need to be considered. Electrical, optical and magnetic properties, such as the dipole moment, dielectric constant, refractive index, magnetic susceptibility, and electrical conductance are relevant too. Furthermore, molecular characteristics, such as the size, surface area and volume, as well as orientational relaxation times have appreciable bearing on the applicability of a solvent or on the interpretation of solvent effects. These properties are discussed and presented in this Chapter. 

As usual, the prime shows that the index does not take the value 0, and represents a sum over the discrete states and integration over the continuum of the unperturbed system. 

It should be noted that no additional assumption is inherent in setting the index of the prime variables equal to unity since in place of 7rj, for example, the following could have been used ... 

Until now research efforts in safety management have been focussing primarily on the number of accidents (system failures leading to personal injuries andlor material damages) as the prime index for system safety. There are three main reasons for redirecting our attention in this respect ... 

The evaluation of (55) is in principle very simple. The quantity < Sl% H Pn > involves only an orbital product (fij ) on the left and a permuted orbital product on the right it therefore reduces in terms of one- and two-electron integrals (< >) < 4>ki4>i,> where for example the primed index / is... 

Pre-1980 —Flat File Storage of Chemical Structures. Computers consisted of mainframe machines (e.g., IBM 3090) and small minicomputers (Digital, Prime). Users connected through low speed serial connections, using "dumb" terminals (no graphics capability) or monochrome vector graphics terminals such as Tektronix and Imlac. Chemical structures were mainly stored as either (l)individ-ual structure files, indexed by name, and handled one or a few structures at a time or (2) in a flat-file database accessed by record number (26). A typical corporate database contained up to a few tens of thousands of structures. 

The Institute of Scientific Information (ISI, Philadelphia, Pennsylvania) operates a computer-based weekly service called ASCA (Automatic Subject Citation Alert). Articles from prime scientific journals may be located through cited item terms as well as through title terms. Clusters of articles with common references will usually be about the same subject, so a reference used as a profile term will locate articles citing that reference, as articles are published. A similar principle is employed in the Science Citation Index for retrospective searching, where all items having a common reference are brought together beneath the item they cite. 

Prime pigments are used for their ability to hide or cover the surface. The term hiding power is used to describe the relative abihty of fixed amounts of different pigments to cover a surface and depends on the difference in refractive indices between the pigment and the binder thus primary pigments usually have high values in refractive index.
