It is a simple matter in electronic notebook space to create multiple threaded views (MTVs) that logically link related elements into a virtual sub-notebook for improved continuity and clarity. For example, most scientists work on many problems in parallel. One must manually page through a cellulose notebook to follow the progress line. It is possible to write forward and backward page pointers (a linked list) within individual experiments in a cellulose notebook to aid the worker and other readers, but this is seldom done. After all, even a complete and up-to-date index is uncommon. [Pg.861]

For example, in Figure 5.11-left-down a bias method is graphically illustrated the real stmcture factor is F, the one calculated from the model is (the sub-index C indicates the calculated nature)- which, despite indexed, provides the calculated phase exp(/a ) which by combining with the observed (measured) amplitude F generates the bias model (calculation + experiment) of the bias structure factor F exp(/a ) this should be closer to the real one than the one F provided by applying of theoretical model alone. Thus, properties of the stmcture will be identified, as close to the real ones, namely if inside the calculated model there were not certain atoms, they will appear in the bias electronic map, built on the bias stmcture factor.
