Fig. 3. Perspective drawing of the main-chain conformation of domestic hen egg-white lysozyme. The view is an elevation from the active-site side of the molecule (Imoto et al., 1972). Only the positions of the a-carbon atoms are shown. An instructive colored painting by I. Geis of the original three-dimensional model of lysozyme is reproduced in the early review by Phillips (1966). Of historic interest is the drawing of the model by the late Sir Lawrence Bragg (reproduced by Blake et al., 1965, and Phillips et al., 1987). It is to be noted that Bragg s diagram is a free-hand drawing and not an accurate computer-generated representation of the molecule. (Reproduced with permission from Imoto et al., 1972.)...

Solution Dyed Nylon (now a product of Invista, which DuPont sold to Koch Industries in 2004). Historically, DuPont s nylon customers purchased raw product and dyed it themselves. More recently, DuPont has offered these customers nylon that is dyed to their specifications in the manufacturing process. This has a number of benefits to the customer including the steadfastness and consistency of the colors. For the environment, this process means more of the overall dying process happens in a centralized location with high environmental controls. From the DuPont business perspective, this adds more value to their customers and raises the cost of switching to another material supplier.
