Removal of a chemical from the HPV Ust required evidence that the chemical was no longer being produced by any company or group of companies at a total aggregate volume of one milUon pounds or greater and the chemical was not likely to become an HPV chemical in the future. The claim had to be verifiable based on business plans, past production patterns, and credible trends in the market.

In an effort to minimize duplicative testing and unnecessary use of test animals, EPA agreed to consider accepting data from existing studies that were not conducted in accordance with appropriate OECD test guidelines, EPA test guidelines, or Good Laboratory Practice Standards, if the data were

However, systems are usually not made up just of computers -rather they will also involve other entities (e.g., devices and humans) which in many cases will not be able to simply forget some of their recent activity, and so simply go straight back to an exact earlier state when told that an error has been detected. Thus forward error recovery (the typical programming mechanism for which is exception handling), rather than backward recovery will have to be used. Each of these complications individually makes the task of error recovery more difficult, and together they make it much more challenging. This in fact is the topic that I and my colleagues have concentrated on these last few years.

Preconcentration A good extraction/back extraction cycle not only results in a cleaner sample, but analytes are concentrated in the process. Obviously, this argues for using the smallest possible back extraction solvent volume. If this volume needs to be manipulated by hand, that is, if it is not a volume resulting from a programmed mechanical device or by switching on a chip, then the minimum volume of the back extraction solvent will probably be about 1 p,L.

The scheme (Fig. 11a) thus provides a possible explanation of the synthesis of different virus proteins at different times and in different amounts (at different speeds), but it does require the existence of an as yet unknown mechanism of independent operation of individual cistrons in accordance with the program for virus development. In other words, it requires a programming mechanism, controlling protein synthesis by the polysome in the same way as a tune is produced from notes obtained by striking the keys of a piano. The scheme (Fig. 11b) resembles the simple repetition of a scale of successive sounds. In this case no notes, i.e.,programmed regulation of activity, are required it is assumed that control is by simple linear succession of the cistron-keys.
