A conclusive view

In this long analysis of the modeling of the separate components we have learned the following  

Adapting these remarks, one may write a tentative analytical expression for AE(R)  

The expansion centers (called sites ) are indicated by the indexes r and t for the molecule A and B respectively. The index n indicates flie behavior of the specific term with respect to the intersite distance R each couple r-t of sites has a specific set of allowed n values. 

The coefficients can be drawn from experimental values (but this is limited to the cases in which there is one site only for both A and B), from ad hoc calculations, or by a fitting of AE values. In the past, large use has been made of experimental AE values, derived, e. g., from crystal packing energies, but now the main sources are the variationally computed 

Expression [8.62] has several merits, but also several defeets. Among the latter we note that given powers of R may collect terms of different origin. For example, the term R describes both the induction dipole-induced dipole interaetion and the dispersion dipole-dipole interaetion two contributions with a different sensitivity with respeet to ehanges in the molecular system. Theory and computational methods both permit getting two separate coefficients for the two contributions. This is done in a limited number of potentials (the most important cases are the NEMOn and file ASP-Wn families of models). The most popular choice of a unique term for contributions of different origin is motivated by the need of reducing computational efforts, both in the derivation and in the use of the potential. To fit a unique coefficient means to use AE values only for two eoeffieients there is the

In a first approximation the average size of pore diameter has no effect on porosity, even though a superficial view leads to other conclusions. A mental experiment may be of assistance imagine a pore and its outside wall, decrease both to identical scale, then the ratio of void to outside volume remains constant. Of course the re-... 

Some concrete conclusions on market evaluation for micro reactors are given by the PAMIR study, described above (see Section 1.8.1.2). In this context, it is worth reviewing general essays on the market evaluation of microsystems technology, since in a broader view they follow the same analysis and come to the same conclusions. 

Structure and mobility of adsorbed molecules may exhibit a wide spectrum of features. As a general view it is commonly accepted that layers are formed on increasing abundance. The mobility of molecules in the first layer depends strongly on interactions present in a given case. Local domains of adsorbed molecules may be formed in the case of non-uniform surface. Analysis of deuteron spectra for a series of molecules adsorbed on neutral alumina led to the conclusion that while the exchange of molecules between layers in a given domain is fast, the diffusion rate between domains is slow [5],... 

Quantum chemical calculations on substituted alkanes are in agreement with a through-space (field) transmission of substituent electrical effects . In view of the ever-increasing evidence for through-space transmission of electrical effects, it is time to make a conclusive statement. There is no inductive-effect component in electrical-effect transmission ... 

In conclusion biocatalysts have acquired many useful applications in a variety of different industries. These genuine commercial achievements are particularly impressive when judged in comparison with a realistic view of technical progress in other closely related fields. Thus one very large pharmaceutical company has introduced only three new fermentations in the last 25 years. In the future big advances are necessary in order to make substantial progress, for instance by learning how to carry out synthetic rather than just degradative reactions, so that effective competition with established chemical syntheses can be established. 

Take responsibility for successful achievement of the purpose. You really need to make it your own personal venture, thus committing yourself to seeing it through to a conclusion. To this end, you will need a personal sense of purpose, mission even - a view of how you want to shape your bit of the world and leave it different to how you found it.
