Another difference between utilities and factories is that most industrial facilities tend to operate boiler plants with a lower quality (and often variable) FW compared to power generators. Although boiler heat flux is usually lower, this practice nevertheless adds an additional water chemistry control burden, especially because most factories do not employ chemists with specific water chemistry duties. 

The scope of any program for BW treatment and steam-water chemistry control necessarily includes surveying, monitoring, and possibly treating or otherwise conditioning various types of water. 

Modifying the mode of boiler operation to reduce boiler startups and wide load swings. Boilers are far less prone to silica vapors when operating at continuous load (provided, of course, that the basic pretreatment and water chemistry controls are in place). 

NOTE This chart assumes oxygen scavenger, polymer, and other necessary water chemistry controls are in place. If the FW is fully softened, there is no benefit in using this program. Employ a phosphate-cycle or alternative program.

The introduction of modem, very high pressure or temperature boilers has led to water chemistry control problems and cause-and-effect corrosion problems due to phosphate hideout. Under... 

The 1997 revision also widened the scope of boiler design types to seven, enlarged the range of acceptable chemical treatments, and simultaneously tightened the water chemistry controls for FT and WT boilers (see Tables 12.9 to 12.15).

Aqueous solubility, potency and permeability are three factors under medicinal chemistry control that must be optimized to achieve a compound with acceptable oral absorption. Typically, a lead (chemistry starting point) is deficient in all three parameters. The inter-relationships of these three parameters has been described in a series of publications from Pfizer researchers [7, 8]. Figure 9.1 depicts graphically the minimum acceptable solubility as a function of projected clinical potency and intestinal permeability. A minimum thermodynamic aqueous solubility of 52...

However, there is a more immediate reason. There is much electrochemistry mixed in with all the rest of the chemistry controlling the behavior of biomolecules. Thus, the peptide groups that make up proteins can be charged (e.g., NH2 can form NH in acid solution, and COOH tends to ionize to form COO + H30+) when the pH... 

In order to understand all aspects of the action of cisplatin as an anticancer agent, further structural research on the complexes between HMG-domain proteins and platinated DNA fragments will be necessary. On the other hand, further studies of small model compounds may furnish several new details of the chemistry controlling cisplatin-DNA interactions.
