During the 1980s, several adaptive controllers were field-tested and commerciahzed in the U.S. and abroad, including products by ASEA (Sweden), Leeds and Northrup, Foxboro, and Sattcontrol. At the present time, some form of adaptive tuning is available on almost all PID controllers. The ASEA adaptive controller, Novatune, was... 

The TPD unit was constructed at the Signal UOP Research Laboratory. It Includes a Carle 111 H gas chromatograph with Pd/Ag hydrogen separator, Leeds Northrup temperature programmer, Bascom-Turner 8000 series recorder with data processing and storage capabilities and a custom designed quartz reactor.

Figure 0.1 Stimulated emission pumping (SEP, Hamilton et al., 1986 Northrup and Sears, 1992) is a new experimental technique for accessing higher-lying vibrational levels of molecules in their ground electronic states. Shown is the SEP vibrational spectrum of S02, where a pair of dips represent one vibrational level. (Adapted from Yamanouchi, Takeuchi, and Tsuchiya, 1990.) The stick spectrum at the bottom represents the position of the vibrational levels given by Equation (0.1) with the constants given in Table 0.1. The bright levels are represented by longer sticks.

Like many classic contributions to science, this spectacular advance was initially met with criticism and even derision. However, Sumner was not deterred he took his show on the road and, through demonstration, convinced many scientists of the protein nature of enzymes. Subsequently, a number of enzymes were crystallized in the 1930s by John Northrup and Moses Kunitz and were also shown to be proteins. These later preparations were essentially pure. Northrup and Kunitz demonstrated that enzyme activity paralleled the amount of protein present, laying the issue to rest. Sumner and Northrup shared the 1946 Nobel Prize in Chemistry. ... 

Unlike most enantio- and diastereoselective direct aldol processes, the enamine-catalyzed aldol reactions are also feasible with aldehyde donors. In a milestone paper, Northrup and MacMillan reported in 2002 that aldehyde-aldehyde aldol...
