At the time of this writing, the most immediate application for the surfaces discussed in this section is to provide models for viscous isotropic phase liquid crystals and certain phase-segregated polymer blends and block copolymers. In this subsection, we show how to calculate diffraction peak intensities from a class of model structures based on these surfaces. The method applies to scattering-density profiles (electron densities for x-ray scattering) determined by ... 

This chapter provides an overview of the model structure base case results for two different data sets detailed sensitivity analyses on capital costs, fuel prices, and construction times and externality analyses for the four key pollutants. 

The three fundamental data models for use in the external model portion of a DSS are record-based models, structurally based models, and expert system-based models. Each of these will now be briefly described. 

Halle and Davidovic developed a dynamic model that explicitly links protein hydrodynamics to hydration dynamics. With the aid of this model structure-based predictions of global biomolecular dynamics become possible. The validity of the model was demonstrated for a set of proteins for which accurate experimental rotational diffusion coefficients are available. Boisbouvier et al derived the rotational diffusion tensor of nucleic acid from relaxation times. 

The reliability of the in silico models will be improved and their scope for predictions will be broader as soon as more reliable experimental data are available. However, there is the paradox of predictivity versus diversity. The greater the chemical diversity in a data set, the more difficult is the establishment of a predictive structure-activity relationship. Otherwise, a model developed based on compounds representing only a small subspace of the chemical space has no predictivity for compounds beyond its boundaries.

The hydrogen atom, containing a single electron, has played a major role in the development of models of electronic structure. In 1913 Niels Bohr (1885-1962), a Danish physicist, offered a theoretical explanation of the atomic spectrum of hydrogen. His model was based largely on classical mechanics. In 1922 this model earned him the Nobel Prize in physics. By that time, Bohr had become director of the Institute of Theoretical Physics at Copenhagen. There he helped develop the new discipline of quantum mechanics, used by other scientists to construct a more sophisticated model for the hydrogen atom. 

In general the relevance of predictions of structure-function relationships based on molecular modeling and structural bioinformatics are threefold. First they can be used to answer the question of which partners (proteins) could interact. Second, predictions generate new hypotheses about binding site, about molecular mechanisms of activation and interaction between two partners, and can lead to new ideas for pharmacological intervention. The third aim is to use the predictions for structure-based drug design. 

Glcp residues, what differs from previous investigations. Based on C-NMR spectroscopy, the sequences of Glcp and Manp were estimated and a model structure for the GM was proposed.
