INDEX segment potentials

Only a little effort is necessary to reduce solvent 1 demand used during reaction scale-up. The quantity used in the laboratory stage was reduced to 59% in the operation stage (Table 5.1). However, related to substrate 2, 96% of solvent 1 is still used. Thus, 87% of the original quantity of solvent will be fed to the incinerator for disposal, while the recycle rate is only 9.1% (from 96% to 87%, Table 5.1). Considering that there is a factor of five difference in solvent 1 demand between the operation scale and the literature procedure (see the segments Solvent of the mass index, in Figure 5.10), the potential for optimiz-... 

Next, we examine the term i2. In a gas-like single segment approximation, this term can be replaced by 1212. The molecular conformation statistics are independent of each other. This might be due to the fact that in the absence of a three-dimensional lattice-potential, nematic shifts of neighboring segments are very likely to occur. In this approximation the configuration does not depend on which individual pair of molecules k, 1 is picked out The molecular structure factor is independent of the indexes k and L Hence 1 inter, d can be written as... 

The CT should demonstrate the entire central airway system, i.e., a spiral data set should be obtained from the mouth to the segmental bronchi. In order to show potential postobstructive complications, the CT should be extended to the diaphragm. To allow appropriate postprocessing of the spiral data set obtained in transversal orientation, collimation should be 2-3 mm, the pitch factor should be 1.5-2, overlap index in reconstruction should be 30%-50%, and a low spatial algorithm should be used. Images should be displayed both at mediastinal and pulmonary window settings. Multiplanar reconstructions and three-dimensional reconstructions as well as virtual endoscopy can be obtained with the...
