INDEX critical values

Chia et al. 1995a). Another index of exposure examined was the number of times the PbB level was above critical values (e.g., 40, 50, 60 ig/dL). Serum P2 X -globulin was the only marker showing a significantly higher prevalence rate ratio of abnormalities (increase) among lead-exposed workers. 

Since the publication of the third edition, additional data have been critically reviewed. New or additional data included in this edition are bioconcentration factors, aquatic mammalian toxicity values, degradation rates, corresponding half-lives in various environmental compartments, ionization potentials, aqueous solubility of miscellaneous compounds, Henry s law constants, biological, chemical, and theoretical oxygen demand values for various organic compounds. Five additional tables have been added Test Method Number Index, Dielectric Values of Earth Materials and Fluids, Lowest Odor Threshold Concentrations of Organic Compoimds in Water, and Lowest Threshold Concentrations of Organic Compounds in Water. 

The unevenness coefficient of particle surface decreased with larger shape index and had a critical value. Therefore, the particle shape modification process was considered in such a way that the submicro uneven particle surface was smoothed at first and, in consequence, the macro shape was processed to be spherical. 

Let us consider, for a given application, a critical property P (initial value P0) and a critical value of this property PF (end-life criterion). At a given time t, the property value is Pt and the corresponding aging index may be defined by... 

The relaxation of a local mode is characterized by the time-dependent anomalous correlations the rate of the relaxation is expressed through the non-stationary displacement correlation function. The non-linear integral equations for this function has been derived and solved numerically. In the physical meaning, the equation is the self-consistency condition of the time-dependent phonon subsystem. We found that the relaxation rate exhibits a critical behavior it is sharply increased near a specific (critical) value(s) of the interaction the corresponding dependence is characterized by the critical index k — 1, where k is the number of the created phonons. In the close vicinity of the critical point(s) the rate attains a very high value comparable to the frequency of phonons.

For a number of other polymers Deeley and Terinzi (1965) have confirmed that there is an unambiguous relation between asrv and the spiral length, which indeed permits a good polymer selection. This does not mean that the mouldability index is beyond criticism. It is found, for instance, that the critical values mentioned do not apply to high-melting aromatic thermoplastics. 

Evanescent electromagnetic waves can be excited at the interface of two optically transparent materials with different indexes of refraction. If a beam of light is incident on the interface from the material with the larger index of refraction and if the angle of incidence exceeds a certain critical value, then there will... 

The use of multivariate reference regions usually requires the assistance of a computer program, which takes a set of results obtained by several laboratory tests on the same clinical specimen and calculates an index. The interpretation of a multivariate observation in relation to reference values is then the task of comparing the index with a critical value estimated from the reference values. This, obviously, is much simpler than comparing each result with its proper reference interval. 

Obviously, for a nonisothermal flow in a circular tube of a power-law fluid with exponential dependence of the consistence factor on temperature and arbitrary index n, the critical value of the volume rate of flow is twice that in the isothermal case. 

Figure 5 shows the calculated potential energy of interaction Vt of AI2O3 particles (t/ = 0.25 pm, A = 4.5 x 10 J, and 0.01 M ionic strength) as a function of the surface-to-surface distance of separation for various conditions of potential in an aqueous suspension. Note that the height of the potential energy barrier increases quite sharply as the potential becomes larger than a certain critical value ( 30 mV in Fig. 5). Therefore, the potential is a very good index of the magnitude of the repulsive interaction between colloid particles. Because of this, measurements of potential are most commonly used to assess the stability of a given colloidal sol.
