Theoretical analysis of electronic couphng in DNA [12] suggests that the limiting beta value—the values that would be accessed for donor and accep-... 

A number of points should be noted concerning the statistics displayed In the table. First, If the researcher wishes to rank the variables In order of their Importance within the equation, absolute values of the beta values are the appropriate Indicators of rank (7, p. 284). Second, the t-values of the regression coefficients give us estimates of the statistical significance of the Independent variables used. Third, the R-square, or coefficient of determination. Is an estimate of the percent of variation In the dependent variable (the functional property) explained by the corresponding regression equation. 

In the past, several terms have been coined to describe the retention efficiency of the filter system beta value, microbiological safety index, reduction ratio, and titer reduction ratio [64,68,72], The log reduction value (LRV) is a filter retention efficiency term that is the logarithm to the base of 10 of the ratio of the number of organisms in the challenge suspension to the number of organisms in the filtrate. 

Columns with equal beta value (P) will provide similar separations under the same analytical conditions. For example, a capillary column with 0.32 pm ID and 0.8 pm phase film thickness could be substituted with a column of same phase with 0.53 pm ID and 1.3 pm film thickness to produce very similar separation. Standard film thickness (0.25 to 0.8 pm) should, however, work for most chemical analyses.

Beta values represent the fraction of free atoms present in the hot flame gases of the flame indicated. These values have been taken from various sources and were either experimentally measured or calculated from thermodynamic data using the assumption of local thermodynamic equilibrium in the flame. These values do not have very good agreement within each element however, the values do provide an indication of the probable sensitivity of the particular flame.

Figures 9.8 and 9.9 shows how Beta affects flux and salt passage (rejection), respectively, for two different brackish water concentrations (assumes membrane will deliver 20 gfd at 400 psi with a rejection of 99% at Beta equal to one (no concentration polarization)).8 From the Figures, it is shown that at Beta values greater than about 1.1, the water flux and salt passage (rejection) are significantly affected by Beta. Also shown is that the effect of Beta on performance is more pronounced at higher TDS feed water than with lower TDS feed water.

Conventional wisdom calls for Beta values less than 1.2 in an RO design to minimize membrane fouling and scaling.9 Table 9.4...

System design plays a role in determining acceptable recovery by an RO. Flow rates per pressure vessel, recovery per module, and BETA values must all be taken into account when considering acceptable recovery by the RO system (see Chapters 9.4, 9.5, and 9.6). The higher the recovery of the RO system, the closer concentrate flow rates and individual module recoveries come to reaching limits recommended by membrane manufacturers. 

The values of BETA are determined by performing creep tests at various temperatures on the pavement mixtures. BETA values used in this study are reported in Table IV.

Later we will see that the nonlinearity is not a problem in use. It is not possible here to go into all the details of NTC theory for temperature coefficient alpha, beta value, self-heating effects, thermal time constant, thermal dissipation constant, stability, and reliability. Good information can be found elsewhere [1, 2] and in NTC manufacturers handbooks, catalogs, or web pages [3-10].
