Several studies have shown an increased frequency of penicillamine adverse effects in patients with low sulfoxidation activity, especially with regard to proteinuria and probably thrombocytopenia and myasthenia gravis (SED-12, 547) (3,196,387,388). The sulfoxidation capacity is expressed as the sulfoxidation index, calculated as the percentage of administered 5-carboxymethyl-L-cysteine (750 mg), excreted as sulfoxides in the urine in 8 hours. A sulfoxidation index above 6% is taken as indicative of relative impairment of sulfoxidation capacity. 

Figure 6 (7). The catalyst activity index, a, is the isomerization rate calculated from the reaction time and the octane numbers of the product, a first-order reaction being assumed.

It is not easy to compare the activity of the V-W-Ti catalysts here tested with the lot of chromia, Pt and Pd based catalysts previously used because they have different shapes (monoliths and spheres) and because very different particle sizes arc involved (having thus very different effectiveness factors). For conqiarison purposes, all X-T curves were adjusted to a simple fust order kinetic model (with rate based on overall volume of catalyst, both for monoliths and for fixed beds). From the kinetic constants so obtained (see details of the method in ref 7), the preexponential factors (ko) of the Arrhenius law and the apparent energies of activation (E, p) were calculated for all catalysts. One example is shown in Figure 17. By the well Imown compensation effect between ko and E,pp, the kg values so obtained were recalculated for a given E.pp value of 44 kJ/mol. Such new ko value was used [7] as an activity index of the catalyst. 

Flash points of mixtures of oxygenated and hydrocarbon solvents cannot be predicted simply. A computer based method is proposed which exhibits satisfactory prediction of such Tag Open Cup flash points. Individual solvent flash point indexes are defined as an inverse function of the component s heat of combustion and vapor pressure at its flash point. Mixture flash points are then computed by trial and error as the temperature at which the sum of weighted component indexes equals 1.0. Solution nonidealities are accounted for by component activity coefficients calculated by a multicomponent extension of the Van Laar equations. Flash points predicted by the proposed method are compared with experimental data for 60 solvent mixtures. Confidence limits of 95% for differences between experimental and predicted flash points are +8.0-+3.0°F. 

The required parameters in the calculation are Ushocked, t/s, and Wp. The shocked refi active index is given by the Gladstone-Dale equation nshocked=l+( -l)Pshocked/p, where p is the initial density of the PMMA (1.186 g/cm ) and n=1.487. Conservation of mass provides the shocked density pshocked=p/(l- Up / s) for a one-dimensional shock compression. Previous studies have validated the Gladstone-Dale model for shocked PMMA up to 22 GPa. [90-91]... 

Italian monitoring data of freshwater samples related to pesticide contamination in 1997 are reported in Table 7. The pesticides are listed in a decreasing order in respea to Priority Index (P.I.)> an index calculated on the basis of pesticide sold quantity, of the field application rates and of the water repartition evaluated with the Mackay model. In Table 7, the percent of laboratories that searched pesticides (%R) and the percent of positive samples (%P) are also showed. It is evident that the monitoring of some pesticides is very poor, even if they have an elevate P.I. Some active ingredients, like metolachlor and terbuthylazine, are contaminants widespread in freshwaters. 

UVA S/NIR Spectroscopy. In previous work witii ZnS c-s particles, we observed oscillations in tire UV/WS spectrum caused by interference patterns between the shell and core materials. (11) The phenomenon is a result of the difference in refi active index between the two layers. Such behavior is predicted by Mie light-scattering theory ch can be used to calculate shell thickness and refiactive index from UVA S data. (22) Oscillations increase in anplitude and the transmission window undergoes a red shift as these properties increase in magnitude. 

The area is a 2000 hectares industrial area, with 200 firms and more than 5000 workers. A large petrochemical park, with a dozen of independent operators, represents the core activity in the cluster. Many small and medium sized facihties are located in the area, including power stations, pharmaceutical and chemical plants, mechanical workshops, and shipyards. The area is served by a large industrial and commercial ports, with related facihties. In a few establishments the major accident hazard legislation (Seveso Legislation) is enforced and thns the risk analysis is much deeper than nsual. Furthermore, according the Itahan implementation of the European Seveso Directive, the data for Mond index calculation are provided by the duty holders. 

Hohm et al. have calculated the static dipole polarizability of P4 clusters using ab initio finite-field MP and coupled-cluster methods. The results have been compared with frequency-dependent measurements obtained fi-om the gas phase refi active index. 

The total activity. A , represents the total amount of energy that flows through the system s energy elements over the given time T, and therefore, it indicates the activity level of the system. This quantity is used to calculate a normalized measure of element importance called element activity index or just activity index and is given by... 

The activity index is calculated for each element in the model and it represents the portion of the total system energy that flows through a specific element. 

At the end of the simulation of the full model, the time response of the output variables in (2.3) is available for the activity analysis. Given these output variables, the element power is calculated. Then, the activity metric is calculated using (2.2). Finally, the activity index in (2.5) of each element is calculated. The activity indices are then sorted in descending order to identify the elements with high activity, considered more important, and low activity, considered less important. The result of the sorting process is the ranking of the element importance and it is represented with the vector r as shown in (2.17). The first element of this vector points to...

The retention index calculation of optically active compounds can be considered as a troublesome issue due to complex inclusion complexation retention mechanisms on CD stationary phases if a homologous series, such as the n-alkanes, is used, the hydrocarbons randomly occupy positions in the chiral cavities. As a consequence, n-alkanes can be considered as unsuitable for retention index determinations. Nevertheless, other reference series can be employed on CD stationary phases, such as linear chain FAMEs and FAEEs. However, retention indices are seldom reported for optically active compounds, and publications refer to retention times rather than indices.

Erythrocyte hemolysis. Hemolysis experiments were performed in PBS using static method, as previously described [2], The degree of hemolysis due to sample activity was calculated as the hemolytic index %H = (Hb - Hbo/Hb,ot) 100%, where Hb is the total amount of released hemoglobin in the assayed sample, Hbo the amount released due to basal hemolysis (200pl erythrocytes incubated with 50pl PBS), and Hb,ot the total amount of released hemoglobin in fully disrupted erythrocytes (0.2 ml erythrocytes in 19.8 ml H2O MilU Q). 

In actual research, the activation index (H, mass ratio of the floating portion to total samples) is used to evaluate the surface modiflcation results of whiskers (refer to the national standard GB/T 19281-2006). The detection process is as follows. Add a certain amount of modified whiskers into 100 ml of deionized water and let it sit until clear after stirring for 1-2 minutes. Then remove the floating portion on the solution surface and collect the sunken powders at the bottom. The latter are Altered, dried, and weighed and the activation index is calculated using the following equation ... 

Scherer and Godoy (2009) developed the antioxidant activity index (AAI) to evaluate antioxidant capacity. The AAI is calculated as follows AAI = DPPHt/ICso. The DPPHt is the final concentration of DPPH in the control (without sample), and IC50 is in pg mE k When AAI < 0.5, the antioxidant capacity is weak, 0.5 < AAI < 1.0 is moderate, 1. 0 < AAI < 2.0 strong, and AAI > 2.0 very strong. Table 29.1 shows some results of antioxidant capacity in foods represented by several types of measures. 

The index of refraction, n X,p,T), depends on the wavelength X, on the total air pressure, on the partial pressures of H2O and CO2, and on the temperature. If the total pressure is measured within 0.5mbar, the temperature T within 0.1 K, and the relative humidity within 5%, the re-fi-active index can be calculated fi-om formulas given by Edlen [4.78] and Owens [4.79].

In spatial repellency assays, a metal test cylinder containing a treated net and another containing a solvent-treated net are connected by a clear cylinder that is placed in the middle. The valves of the intersections are closed and 20 mosquitoes are introduced into the clear central cylinder, which is darkened by opaque felt. The end caps of the test cylinders are not covered to allow light to enter the system and help mosquitoes to orient. After an adaptation period of 30 seconds, valves are opened and the distribution of test mosquitoes among the test chamber (with treated net), central chamber, and control chamber (with solvent-treated net) is recorded after 10 minutes. With these numbers, a spatial activity index (SAI) can be calculated as follows ...
