Concentration defined

In reality, oxygen concentration never reaches the concentration defined in the proposed model, since the microbial activities at optimal and maximum cell density would reach the point where oxygen depletion takes place.5... 

Hyperuricemia Elevated serum uric acid concentration, defined as a level greater than 7.0 mg/dL. 

The maximum outlet concentrations from each mixer are given in Table 6.8. The maximum outlet concentrations given in the table stem from approximate process data. It is important to notice that there is maximum outlet concentration defined for only one component from each mixer. This is since each mixer will at any point only contain residue of a specific product. The inlet and outlet concentrations of the other products will be equal. The outlet concentration from each mixer varies due to the varying nature of the products.

We suggest using a new parameter, the minimum reportable concentration, defined as the concentration whose confidence band just includes zero (5.). This parameter is obtained by reducing the value of signal Yo, figure 4, until the band around predicted concentration, Xo, just touches zero. For example, for the determination of iron in water by AAS, (data given in Table III) the detection limit, defined as the concentration at which the... 

The Student s t-test probability (TP) measures the geochemical contrast (essentially equivalent to precision) of an exploration method. This probability identifies the likelihood that anomalous and background concentrations, defined by a specific threshold, are derived from the same population by measuring the difference between the mean anomalous and background concentrations. The lower the TP e.g. the minimum TP for any threshold MTP), the more geochemical contrast and the more likely that random variations will not influence or change the results. 

Section II shows that the dimensionless external velocity field uJU, UqIU) is a function of dimensionless position r/a, 0) and k for creeping flow. The dimensionless concentration defined in Eq. (1-45) is a function of these quantities and of the Peclet number, Pe = 2aU/. Hence the Sherwood number, Sh = is a function of k and Pe (with additional dependence on Re unless the creeping flow approximation is valid). The exact solution of Eqs. (3-39) to (3-42) with the Hadamard-Rybczynski velocity field is not available for all values of Pe and K, but several special cases have been treated. 

We have carried out a wide range of studies concerned with the dextran concentration dependence of the transport of the linear flexible polymers and have varied both molecular mass and chemical composition of this component. Moreover, we have studied the effect of the variation of the molar mass of the dextran on the transport of the flexible polymers 51). In general, the transport of these polymers in dextran solutions may be described on common ground. At low dextran concentrations the transport coefficients of the polymers are close to their values in the absence of the dextran and may even exhibit a lower value. This concentration range has been discussed in terms of normal time-independent diffusional processes in which frictional interactions predominate. We have been able to identify critical dextran concentrations associated with the onset of rapid transport of the flexible polymers. These critical concentrations, defined as C, are summarized in Table 1. They are...

Figure 5. Data from the literature (56, 80, 99, 164, 195, 220, 222, 223, 243) indicate that diffusive fluxes of sulfate (calculated from 40 pore-water profiles measured with pore-water equilibrators) are linearly related to concentrations of sulfate in the overlying lake water. The correlation is significant (p < 0.05) both with (r2 = 0.991) and without (r2 = 0.42) the two lakes with high sulfate concentrations. The strong correlation suggests that variations in the depth interval within which sulfate is consumed and in the minimum sulfate concentration defining the gradient are relatively unimportant in determining the flux, compared to variations in sulfate concentrations defining the upper end...

Changes in surface pressure with time or concentration can be used to measure various fundamental properties. Changes in surface pressure versus protein concentration curves can be used to determine the excess surface concentration (critical micelle concentration), defined as the amount of protein at the surface divided by the surface area. Indicates minimum amount of protein needed to form an emulsion. 

The Surface concentration defined in this manner depends upon the location of the dividing plane y. This can be seen by considering another dividing plane at position y". Now the volume assigned to phase I is increased by (y" — y )As while the volume of phase II decreases by the same amount. Substitution into equation (12.55) shows that the surface concentration, now given by T", differs from T by the amount... 

Plots of surface tension versus concentration for n-pentanol [49], LiCl (based on Ref. [50]), and SDS in an aqueous medium at room temperature are shown in Fig. 3.7. The three curves are typical for three different types of adsorption. The SDS adsorption isotherm is typical for amphiphilic substances. In many cases, above a certain critical concentration defined aggregates called micelles are formed (see Section 12.1). This concentration is called the critical micellar concentration (CMC). In the case of SDS at 25°C this is at 8.9 mM. Above the CMC the surface tension does not change significantly any further because any added substance goes into micelles not to the liquid-gas interface. 

Not only was a larger latex examined in more detail but also a greater study was made of the concentration dependence of the light scattering. The concentration dependence of lateral scattering was first examined by Heller and Tabibian (7). They measured the concentration dependence of the specific turbidity I90/I0c and carried out an extrapolation to zero concentration defined by... 

Also, measurement endpoints such as inhibition concentration related to x% of effect (ICx) compared to a control, can be plotted versus time for each bioassay. Mathematical models for such "toxicity curves" could generate an infinite time Inhibition Concentration related to a x% of effect (°°ICx) for each bioassay. Such data, equivalent to the incipient lethal concentration defined for example by Giesy and Graney (1989), are valuable in terms of long-term environmental impact assessment. 

Virtually all the research on herbicides In forest streams shows that the residue levels reach a maximum shortly after application and then decline rapidly. Although the Instantaneous maximum concentration may be 0.037 mg/liter, the concentration 1 hour later may be 0.010 mg/liter, 0.002 mg/liter at 24 hours, and below the detectable level after 48 hours. The problem Is to evaluate this type of dynamic exposure in terms of the type of Information that Is available from traditional testing (2). The approach often taken Is to assume that the maximum concentration defined In field monitoring was present for a full 48 or 96 hours, and to estimate toxic effects based on 48- or 96-hour toxicity tests. The consequence in almost... 

That is, the particular function of the three concentrations defined by Q (reaction quotient) is always the same at equilibrium. This is true even though any individual concentration may vary by as much as a magnitude of 10. This unifying principle allows the calculation of conditions at equilibrium under virtually any set of conditions.

Cell growth was monitored by measuring the absorbance at 600 nm (OD600 (DU Series 600 Spectrophotometer Beckman, Fullerton, CA). PHA concentration and monomer composition were determined by gas chromatography (Donam, Seoul, Korea) equipped with a fused silica capillary column (Supelco SPB -5,30 m x 0.32 mm id, 0.25 pm film Bellefonte, PA) using benzoic acid as an internal standard (31). Cell concentration, defined as dry cell weight per liter of culture broth, was determined as previously described (14). The residual cell concentration was defined as the cell concentration minus PHA concentration. The PHA content (wt%) was defined as the percentage of the ratio of PHA concentration to cell concentration. 

The rate constants (together with the model and initial concentrations) define the matrix C of concentration profiles. Earlier, we have shown how C can be computed for simple reactions schemes. For any particular matrix C we can calculate the best set of molar absorptivities A. Note that, during the fitting, this will not be the correct, final version of A, as it is only based on an intermediate matrix C, which itself is based on an intermediate set of rate constants (k). Note also that the calculation of A is a linear least-squares estimate its calculation is explicit, i.e., noniterative.
