Subsurface runoff. When precipitation hits the land surface, the vast majority does not go directly into the network of streams and rivers in fact, it may be cycled several times before ever reaching a river and the ocean. Instead, most precipitation that is not intercepted by the vegetation canopy and re-evaporated infiltrates into the soil, where it may reside as soil moisture, percolate down to ground-water, or be transpired by plants.

Since the networks were formed and tested in bulk, V = Vf V0, and a slope of one would be expected. Thus, both the slope and the intercept are in good agreement with the predictions of equation (7). Moreover, the excellent fit of the eight different... 

The plot Ge/Te vs. vg/Te yields then A from the slope and from the intercept (Langley-Greassley plot). The applicability of this plot will be commented on below and it will be shown that this plot is not very suitable for endlinked networks with varying as a function of the conversion or molar ratio of components. The similarity between the shapes of v e and Te and the resulting relative constancy of /Tg is the reason. The other disadvantage of analysis of experimental data using Eq.(1) or (5) based on the difference between the values Ge and Ve is the sen-... 

Operation Topaz, launched by the Board in collaboration with concerned Governments in 2000, continued to prove effective during 2004 in providing participating Governments with an effective tool to monitor the licit international trade in acetic anhydride, a critical chemical used in the illicit manufacture of heroin and also in providing an essential network to quickly track back seized or intercepted shipments of the substance. 

At the same time, the Netherlands authorities identified a network attempting to divert ergotamine when a consignment of 5 kg of the substance was intercepted en route from Slovenia, through the Netherlands, to Suriname. The consignment had been declared as pharmaceuticals . The actual destination of the substance is not yet known. 

The last two columns in Table I give the intercept values of Mg/Mg in Figure 6 and the corresponding values of shear moduli of the dry networks relative to those of the perfect networks. The values of G/G° for V = > are estimates of the maximum values obtainable for... 

The positive intercepts in Figure 7 show that post-gel(inelastic) loop formation is influenced by the same factors as pre-gel intramolecular reaction but is not determined solely by them. The important conclusion is that imperfections still occur in the limit of infinite reactant molar masses or very stiff chains (vb - ). They are a demonstration of a law-of-mass-action effect. Because they are intercepts in the limit vb - >, spatial correlations between reacting groups are absent and random reaction occurs. Intramolecular reaction occurs post-gel simply because of the unlimited number of groups per molecule in the gel fraction. The present values of p , (0.06 for f=3 and 0.03 for f=4 are derived from modulus measure- ments, assuming two junction points per lost per inelastic loop in f=3 networks and one junction point lost per loop in f=4 networks. 

We again consider a network crosslinked by actin binding protein. The number of crosslinks that are formed. A, is given by Equation 10, and a plot of G vs (the total amount of added ABP) is shown, schematically, in Figure 3. Both the slope and the intercept provide information about the kinetic parameters of network formation. Elasticity determinations clearly can be used to assess the amount of crosslinking protein in an assembly if all other conditions are kept constant, G varies linearly with consequently, after appropriate calibration (in principle with only two data points), elasticity measurements could be used for quantitative assessment of the efficacy of biochemical purification procedures. Parenthetically, we note that if conditions can be arranged such that K S 1, gives a direct measure of the number of nuclei iIq. 

In Eq. (1), a is the equilibrium stress (Nm 2) supported by the swollen specimen a is the stretched specimen length divided by the unstretched length (extension ratio) v2 is the volume fraction of dry protein and p is the density of dry protein. In the common case of tetrafunctional crosslinks, the concentration of network chains n (mol network chains/g polymer) is exactly one-half the concentration of crosslinks, so that n = 2c. The hypothesis that a specimen behaves as if it were an ideal rubber can be confirmed by observing a linear relation with zero intercept between a and the strain function (a — 1/a2) and by establishing a direct proportionality between a and the absolute temperature at constant value of the extension ratio, as stipulated by Eq. (1). 

If material is neo-Hookean, its Mooney-Rivlin plot ought to give a horizontal line and hence yield C2 = 0. Thus one is tempted to consider that nonzero C2 must be associated in one way or another with the deviation of a given material from the idealized network model, and it is understandable why so many rubber scientists have concerned themselves with evaluating the C2 term from the Mooney-Rivlin plot of uniaxial extension data. However, the point is that a linear Mooney-Rivlin plot, if found experimentally, does not always warrant that its intercept and slope may be equated to 2(9879/,) and 2(91V/9/2), respectively. This fact is illustrated below with actual data on natural rubber (NR) and styrene-butadiene copolymer rubber (SBR).
