Strategy and conditions

Extensive research has focused on the synthesis of structurally modified sialic acid derivatives and sialylmimetics as probes or potential inhibitors of specific sialic acid-recognizing proteins, and several comprehensive overviews have been published [26, 30-34], An underlying theme in efforts directed toward the development of novel sialic acid derivatives as biological probes is the complexity of the chemical manipulations associated with sialic acids [30, 32], The chemical strategies and conditions for sialylation are discussed in Chapter 5. 

Numerous applications for online LC-GC have been described for all important fields of analysis (summarized in Further Reading), but more than half of the methods applied concern mineral oil and edible oil or fat. A few are briefly outlined to illustrate typical strategies and conditions. 

The next section analyzes different high-relleclion stractures convenient for cavity enhancement. It also considers strategies and conditions of their use. 

The scope of this chapter is to show how to select a strategy and to make calculations to provide efficient room air conditioning for an industrial enclosure. Design examples for simplified scenarios include different ways to condition industrial halls. 

The clarification of the room air conditioning strategies and their separation frtim the practical methods at present creates space for creativity and new innovations and their evaluation. 

The TSE model of causation that accidents are primarily due to individually controllable unsafe acts is unlikely to be modified over time. This is because very little evidence on the background and conditions which led up to an accident will be collected. The data collection strategy is therefore likely to remain static, since the data collected wiU, by definition, not contradict the underlying assumptions. 

Of course, water molecules are not NMR silent and NMRI engineering has, indeed, advanced at a remarkable pace to provide extraordinary technical capabilities. These capabilities now enable studies of systems beyond those in the biomedical arena, systems that are, in many respects, far more technically challenging. This has led to the development of innovative and fascinating strategies and tactics to deal with NMRI-unfriendly samples and conditions. 

Conditions during start-up can have a dramatic impact on time required to reach reasonable performance levels and on the ultimate reactor performance. Dilution rate, loading rate as measured by chemical oxygen demand (COD), carrier choice, inoculum amount, inoculum strategy, and inoculum species distribution are critical parameters (Sreekrishnan et al., 1991 Araki and Harada, 1994 Austermann-Haun et al., 1994 Yongming et al., 1993). Pore characteristics have a strong influence on time required for start-up and on the ultimate biomass density in the... 

The boundary conditions too were known. It would not be as easy as handling an infinite periodic solid, but a number of us set to work. The special demand of chemistry was to quantify very small molecular changes. Successes came slowly, but with the development of computers and a lot of careful, clever work, by the 90s the quantitative problem was essentially solved. The emergent hero of the chemical community was John Pople, whose systematic strategy and timely method developments were decisive. The methods of what is termed ab initio quantum chemistry became available and used everywhere.
