The computational efficiency is a major advantage of CSP and CI-CSP, and we expect that in the forthcoming few years CSP-based methods will be extensively used as practical tools for the study of an increased range of dynamical processes in large systems. 

Manufacturing approaches for selected bioproducts of the new biotechnology impact product recovery and purification. The most prevalent bioseparations method is chromatography (qv). Thus the practical tools used to initiate scaleup of process Hquid chromatographic separations starting from a minimum amount of laboratory data are given.

Photoluminescence is a well-established and widely practiced tool for materials analysis. In the context of surface and microanalysis, PL is applied mostly qualitatively or semiquantitatively to exploit the correlation between the structure and composition of a material system and its electronic states and their lifetimes, and to identify the presence and type of trace chemicals, impurities, and defects. 

Finally, in this part of the work we would like to discuss to some extent practical tools to obtain thermodynamic properties of adsorbed fluids. We have mentioned above that the compressibility equation is the only simple recipe, for the moment, to obtain the thermodynamics of partly quenched simple fluids. The reason is that the virial equation is difficult to implement it has not been tested for partly quenched systems. Nevertheless, for the sake of completeness, we present the virial equation in the form [22,25]... 

The first modeling software which allowed for the optimization of nonlinear separations by SMB was presented in the early 1990s [46]. Today, numerous publications from academia allows one to have a better understanding of the SMB system [47-51]. Industry now has the practical tools for modeling SMB for quick and efficient process optimization [41, 52]. 

Nevertheless, these correlations are very practical tools for tracking unit performance and for troubleshooting. They are also important in process design and catalyst research. 

This interplay of the many variables is extremely complex and involves a matrix of the many variables. As an example in the molding simulation TMconcept system programmed Molding Cost Optimization (MCO) of Plastics Computer Inc., Dallas, TX, there are well over 300 variables. It is not reasonable to expect a person using manual methods to calculate these complex interactions even if molding only a modest shaped product without omissions or errors. Computerized process simulation is a practical tool to monitor the influence of design alternatives on the processability of the product and to select molding conditions that ensure the required product quality (3).

To develop a practical tool that can help the chemist to design organic syntheses. 

Another practical tool is dynamical decoupling, a technique that uses sequences of fast qubit rotations to mitigate the effects of decoherence. The pulse sequences are designed such that the interactions of each qubit with its environment tend to average out [34, 35]. While still a major concern, decoherence may thus not be the strong impediment it originally seemed to represent for the advent of QC. 

The practical questions concerning laser chemistry may be tersely stated. (1) Will it work If so, (2) is it interesting as opposed to being a trivial extension of known, non-laser photochemistry (3) Is it a practical tool for real chemists as opposed to full-time laser technologists And, (4) are the goods worth the price charged - is it economically worth the effort To make a long story short, the answers are (1) yes, in many but not all cases (2) yes (3) almost and (4) yes, in some cases, but the product had better be valuable. 

In spite of the various CL reactions reported so far, only a few are used as practical tools for CL detection in HPLC [2, 3],... 

Chemical engineers, however, have to find practical ways for dealing with turbulent flows in flow devices of complex geometry. It is their job to exploit practical tools and find practical solutions, as spatial variations in turbulence properties usually are highly relevant to the operations carried out in their process equipment. Very often, the effects of turbulent fluctuations and their spatial variations on these operations are even crucial. The classical toolbox of chemical engineers falls short in dealing with these fluctuations and its effects. Computational Fluid Dynamics (CFD) techniques offer a promising alternative approach. 

Strictly speaking, given the violations of the assumptions underlying Eq. (5) discussed earlier, the concept of aw should not be applied to food systems. However, the concept of aw has proven to be an extremely useful and practical tool in both the food industry and in food science research (Franks, 1991). Rather than discarding the use of aw in foods, perhaps it would be more prudent at this point for one to stress the time-dependent nature (i.e., kinetics) of aw measurements and perhaps, as suggested by Slade and Levine (1991) and Fennema (1996), to use the term relative vapor pressure (RVP, the measured term) in place of aw (the theoretical term). To avoid confusion, the term aw will continue to be used in this review, with the understanding that what is most often being measured is RVP.
