A typical problem in thermodynamics of systems that are far from their equilibrium is the analysis of the stability of stationary states of the system. Thermodynamic criteria of the stability of stationary states are found the same way as for systems that are far from and close to thermodynamic equilibrium (see Section 2.4) by analyzing signs of thermodynamic fluxes and forces arising upon infinitesimal deviation of the system from the inspected stationary state. If the system is in the stable stationary state, then any infinitesimal deviation from this state must induce the forces that push it to return to the initial position. 

For bubble-cap plates, hydraulic-gradient must be given serious consideration. It is a function of cap size, shape, and density on the plate. Methods for analyzing bubble-cap gradient may be found in the chapter by BoUes (Smith, De.sign of Equilibrium Stage Proce.s.se.s, Chap. 14, McGraw-Hill, New York, 1963) or in previous edition of this handbook. 

If both maternal toxicity and effects on the conceptus have been found, the data should be examined on an individual animal basis to determine whether the females showing the most marked toxicity produced the offspring with the effects. In the author s experience, it is generally the case that there is no correlation on an individual animal basis between the maternal toxicity and the effects on the conceptus it is, therefore, not logical to posit a relationship between maternal toxicity and the effects on the conceptus. In these cases, any submission should contain a statement that the data have been analyzed to look for such a correlation and should produce confirmatory data. The confirmatory data should clearly demonstrate a relationship between the worst effects on the adults and the effects on reproduction. A simple list of unquantified physical signs affecting the whole group, for example, would not prove a connection. 

Several studies have reported antibodies being produced in response to an HDl inhalation exposures. In one study, 149 men and 1 woman were selected to prospectively evaluate any clinical signs of illness associated with HDl exposure and, by blood antibody production, to both HDl and HDl trimer. These workers were employed in a factory that spray-painted trucks with paint containing HDl and HDl trimer. Questionnaires were distributed that asked about clinical symptomology, blood samples were taken periodically for antibody determination, and the ambient air in their work environment was sampled for HDl and HDl trimer concentrations over an 18-month period. Serum samples were analyzed via an ELISA for antibodies to HDl and/or HDl trimer. Mean levels of exposure for both HDl and HDl trimer were found to be extremely variable. For the HDl monomer, the levels were between <0.08 and... 

We five in the age of quality. Quality is measured, analyzed, and discussed. The simplest product and the most trivial service come from quality-assured organizations. Conspicuously embracing quality is the standard of the age. Even university faculty are now subject to quality audits of their teaching. Some of these new-found enthusiasms may be more appropriate than others, but I have no doubt that proper attention to quality is vital for analytical chemistry. Analytical measurements affect every facet of our modern, first-world fives. Health, food, forensics, and general trade require measurements that often involve chemical analysis, which must be accurately conducted for informed decisions to be made. A sign of improvement in developing countries is often a nation s ability to measure important aspects of the lives of its citizens, such as cleanliness of water and food. 

Little has been known about ICD of dyes bound to polysaccharides. Nishida and Iwasaki 237 first found that AO molecules bound to carboxymethylcellulose (CMC) in aqueous solution exhibits ICD bands in its absorption region. The CD signs, positive at 425 nm and negative at 450 nm, were assigned to a left-handed configuration of the bound AO molecules. Hyaluronic acid also was analyzed in terms of the ICD of AO bound to it 238). In these cases, the helical handness of the polysaccharides had not been well defined. 

There are, however, relatively few signs that this has moved from being a niche activity to being part of the mainstream world of investment. For example, only three of 35 SRI research organizations evaluated by SustainAbility in Values for Money are found to currently analyze the link between social/environmental issues and material impacts on investment value drivers (Beloe et al., 2004). These are SAM Research, Innovest, and CoreRatings. These have the greatest potential to cross over into more widespread use among mainstream investors.
