The formal study of CA really began not with the simpler one-dimensional systems discussed in the previous section but with von Neumann s work in the 1940 s with self-reproducing two-dimensional CA [vonN66]. Such systems also gained considerable publicity (as well as notoriety ) in the 1970 s with John Conway s introduction of his Life rule and its subsequent popularization by Martin Gardner in his Scientific American Mathematical Games department [gardner83] (see section 3.4-4). 

Perhaps the single most studied (and joyfully played with) rule - certainly the most famous is the two-dimensional Moore neighborhood binary-valued CA invented by John H. Conway, and popularized extensively by Martin Gardner in his Mathematical Gaines column in Scientific. American in the early 1970 s ([gardnerTO], [gardnerTl], [gardner78]). 

Now that an haustorial inducing factor has been characterized in a host plant that could be grown in the laboratory, the levels of the compounds actually exuded could be analyzed. John Steffens and Rody Spivey focused on developing methods that would allow for suitable quantitation. Efforts were made to quantitate not only the terpenoid components, but also the flavanoid, genistein (4, 5,7-trihydroxyiso-flavone), which was found to be a major isoflavone of Lespedeza. Genistein was analyzed to gain an estimate of levels of phenylpro-... 

He was a leader on the street, and in the committee rooms where the nitty-gritty of hazardous materials response in the United States is thrashed out. Chief John Eversole was approachable to all persons and eloquent in expressing his thoughts. He also had a definite command presence on an incident scene gained through long command experience. John, we are going to miss you. 

Francis Mercurius van Helmont (see plate 12), the son of John Baptist, bom in 1618, gained the reputation of having also achieved the magnum opus, since he appeared to live very luxuriously upon a limited income. He was a skilled chemist and physician, but held many queer theories, metempsychosis included. 

We can also look at other literature datasets to gain an idea of how similar our compounds are to compounds for which QMPRPlus gives very good predictions. We have looked at four simple descriptors molecular weight, topological polar surface area [40], chemical complexity [41], and rotatable bond count, using John Bradshaw s... 

Rubber gained worldwide importance with the invention of the air-filled or pneumatic tires by a Scotsman, John Dunlop, in 1888. He had a successful veterinarian practice in Belfast. In his off time he worked to improve the ride of his son s tricycle. His invention happened at the right time. The automobile was emerging and the air-filled tires offered a gentler ride. Thus was begun the tire industry.

Hales then refers to John Freind who has from the same principles given a very ingenious Rationale of the chief operations in Chymistry. Freind was one of the Englishman who in the late seventeenth and early eighteenth centuries were trying to apply mechanical principles to chemical phenomena. But, Hales added, it is important to gain more information from experience. 

In retrospect, it seems probable that the medical profession gained far more from Link s successes as an agricultural chemist than it could have from his practice of medicine. The discovery of Dicumarol and its adoption as an important clinical anticoagulant, and the synthesis of Warfarin and its development as a widely used rodenticide—these accomplishments, which will not be described in this article, alone were more than sufficient to make Karl Link an important name in science. For his work on Dicumarol, Link received the Cameron Award from the University of Edinburgh in 1952, the Lasker Award in 1955 and 1960, the John Scott Award in 1959, and the Kovalenko Medal of the National Academy of Sciences in 1967. He was a Harvey Lecturer... 

In rats and rabbits, inhalation of chlorobenzene vapors at concentrations up to 590 ppm during periods of major organogenesis did not produce structural malformations (John et al. 1984). This value has been presented in Table 2-1 and plotted in Figure 2-1. The highest dose resulted in maternal toxicity, as indicated by elevation of liver weights (both species) and decreased food consumption and body weight gain (rats only).
