Figures 2.2, 2.3 and 2.4 show relationships between y, and Xj that always increase or always decrease over the domains shown. The lowest and highest values of the response y, lie at the limits of the x, factor domain. Figure 2.2 is a response surface that is monotonic increasing that is, the response always increases as the factor level increases. Figures 2.3 and 2.4 show response surfaces that are monotonic decreasing the response always decreases as the factor level increases.

This equation, formulated for liquids, also describes the behavior of solids if q = 00 is assumed in the latter case. Experimentally it is found that J(t) — t/r[ — Jg is a monotonous increasing function of time that reaches the value Jj as t 00. The function l (t) modulates the entropic response to the shear stress the time dependence of this function is indicated in Figure 5.15. Since W( — 0) is a monotonous decreasing function of time, d it — Q)/d(t — 0) is an increasing function of time whose slope increases considerably as 0 approaches t. Consequently, (0 behaves as a memory function that mod-... 

UV-visible spectrophotometry enables giving indications about the pollution maturation level in contaminated soils. Stabilised leachates from old contaminated soils are characterised by a monotonous decreasing spectrum (soil A), while younger ones show a specific spectrum where additional compounds are responsible for visible accidents (soil B). 

Fig. 17 A series of snapshots of a dynamic Monte-Carlo simulation after a negative-going potential step to 20 mV below the transition between the low coverage and mixed X. 3) layer (peakAi). Cu is represented by the filled circles (.), sulfate by a triangle (A), and the unoccupied sites are open circles (.). After the step, a fraction of sulfate desorbs, but the remaining sulfate combines with the newly adsorbed copper to form a loose domain. With time, this domain fills in and grows. The MC-current response reproduces qualitatively the monotonically decreasing experimental transient in panel Ai, Fig. 16 (with permission by P. A.

That this form does indeed hold had been demonstrated for the cavitation of glassy polypropylene (Mott et al. 1993) in a computational study furnishing the validity of this extension of the universal binding-energy relation to symmetrical bulk response. The additional attraction of this expression is that it points out directly that application of a pressure produces symmetrical elastic compaction in an isotropic solid. However, more interestingly, one notes that, when dilatation is imposed, the bulk modulus monotonically decreases and eventually, at a dilatation of 1 /p, vanishes. This also leads to the observation that, if dilatation results from thermal expansion in response to a temperature increase, the bulk modulus also decreases. This simple observation represents the essence of the temperature dependence of all other elastic constants in anisotropic solids, beyond the mere effect on the bulk... 

Consider the application of a constant shear stress ao to a viscoelastie solid at t = 0 in simple shear (or alternatively in tension as pure shear). The time-dependent response is ideally an instantaneous elastic flexure followed by time-dependent creep as depicted schematically in Fig. 5.1(a), which at a monotonically decreasing rate asymptotieally approaches a constant shear strain proportional to the applied shear stress. Removal of the shear stress at any time t results in an instantaneous elastic recovery followed by a reverse creep response that asymptotically returns the solid to its initial state, as also depicted in Fig. 5.1(a). 

There are some informations about monotonous decrease of the equilibrium surface tension, dilatational elasticity, and adsorption of lysozyme for non-ionic surfactant decyl dimethyl phosphine oxide (Cj DMPO) as the concentration of surfactant increases in the mixture. However, in the case of mixtures of non-ionic surfactants with more flexible proteins like P-casein, the elasticity of the interfacial layer decreases before passing through a maximum as the concentration of surfactant increases [7], Possibly, the weaker interfacial network formed by P-casein as compared to globular proteins determines the dilatational response of the mixtures. The same picture was shown for the system P-casein mixed with dodecyl dimethyl phosphine oxide (C,2DMPO). For all studied frequencies (0.005-0.1 Hz) the elasticities for adsorption layers have a maximum about 4x10" mol/1 Cj2DMPO concentration. It was shown the obtained values are very close to those measured for the surfactant alone. Thus, in this concentration region the surfactant dominates the surface layer. In our case we have... 

If u k) is a periodic and symmetric signal, the filter outputs for even values of r (r = 0, 2, 4,...) are equal to zero after one complete period N. In addition, the magnitudes of the nonzero filter outputs corresponding to r = 1, 3,... decrease as r increases. Therefore, in this situation, the only terms required to accurately describe the process output y k) in Equation (8.3) for processes with a monotonically decreasing frequency response may be those with r = 1, 3 and 5. However, because output disturbances and measurement noise are encountered in most practical situations, u k) is seldom an ideal periodic and symmetric signal. In many cases though, u k) would be nearly periodic and the parameter N could be chosen based on... 

In the low-hnmidity regime (RH < A), Ac ) increases monotonically. When RH = A, the K salts show a decrease in Ac ), followed by a constant platean for RH > A. For NaCl, Ac ) continnes to increase bnt at a lower rate. The response time t also shows a different behavior below and above A, which is manifested by a change in the slope of log(T). 

The Responses for 9, 9jjo> and are shQvm in Fig 12. The value of 9fl, which is initially 0.925, decreased during the period of NO exposure at the same time that the value of 0jjq increases rapidly from zero. It should be noted that the predicted rate of accumulation of adsorbed NO is qualitatively consistent with the dynamics of the band appearing at 1680 cm-, associated with No shown in Fig. 4. It is seen, though, that while the experimental results exhibit a short induction period followed by a rapid rise in the absorbance of the 1680 cm-- - band to a saturation level, the predicted curve shows a smooth monotonic increase in 0jjo ... 

Trend tests seek to evaluate whether there is a monotonic tendency in response to a change in treatment. That is, the dose response direction is absolute as dose goes up, the incidence of tumors increases. Thus the test loses power rapidly in response to the occurrences of reversals , for example, a low-dose group with a decreased tumor incidence. There are methods (Dykstra and Robertson, 1983) which smooth the bumps of reversals in long data series. In toxicology, however, most data series are short (that is, there are only a few dose levels).
