2748 ination of pet food, a detection method involving liquid chroma-tography–mass spectrometry became widely available and reliably identifies both cyanuric acid and melamine. A number of suspect foods from China tested by the FDA were found to contain melamine (see table), and more are being reported around the world each week. Furthermore, the FDA has found trace levels of melamine in severa...

We describe Jcon, a new, Java-based implementation of the Icon programming language. The implementation includes a compiler and runtime system. The runtime system is novel in its concise and efficient object-oriented implementation of a dynamically typed language, as well as its simple mechanism for realizing Icon generators.

1. Introduction In an earlier report [1], a model for string pattern matching in the style of SNOBOL4 was developed using Icon. That report showed how most of the pattern-matching mechanism of SNOBOL4 could be translated into Icon and, in effect, provided a model for implementing pattern matching in the style of SNOBOL4.

This study investigated the orthodontic treatment of 429 consecutive patients [172 male (40.1 per cent) and 257 female (59.9 per cent)] carried out by 10 orthodontic specialist practitioners in seven European countries [two in the Czech Republic (A and B), two in Germany (A and B), Italy, Latvia, Lithuania, and Netherlands, and two in Slovenia (A and B)]. The median age of the patients at the s...

The rice water weevil, Lissorhoptrus oryzophilus Kuschel, is the most destructive insect pest of rice in the United States and is a particularly severe pest in Louisiana. The current management program for this insect in Louisiana relies heavily on insecticides, most notably the seed treatment fipronil (Icon). Diversification of the management program by incorporation of alternative strategies ...

1. Introduction Icon [1,2] is a high-level, general-purpose programming language that emphasizes string and structure processing. Icon bears a heritage from SNOBOL4 [3] and SL5 [4] and is partly the result of attempts to improve on these languages and to correct some of their notable defects.
