Fig. 10.1 Diagram of the model. F and T are the reservoir species. A and B are the cycle intermediates, interconverted by the enzymes a and Arrows indicate reactions, circles indicate regulation. (From [2].)...

FDA regulated unless otherwise indicated. Regulated by the U.S. Food and Drug Administration as an indirect food additive under Title 21 of the U.S. Code of Federal Regulations (21 CFR), Part 175 (Adhesives and Coatings) and/or Part 177 (Polymers). 

The cabinet system includes full radiation safety in the form of dual, forced breaking door interlocks so that there can be no risk of exposure outside the cabinet. Equally the system is equipped with emergency stops and red lights indicating when X-rays are on, in accordance with the international regulations. 

This poster indicates the structures of the compounds involved in a reaction, the enzymes catalyzing a reaction, the coenzymes and regulators involved, and whether such a reaction is a general pathway occurring in all species, or a pathway specific to higher plants, animals, or unicellular organisms. 

Use of chain transfer agents may be indicated to regulate u and thus avoid some of the difficulties mentioned in items (3) and (4). 

Concentrations over 8 wt % are classified as corrosive Hquids by the Department of Transportation (DOT). The Bureau of Explosives regulation (132) classifies all solutions containing 20 wt % and greater as oxidizers and corrosives. The product containers must have identifying labels (dmms) or placards (tank cars, tank trailers) indicating that the contents are an oxidizer and corrosive material, UN 2014 or UN 2015. Bills of lading must also be so identified. Tank cars and tank trailers are constmcted from high purity aluminum or 300 series stainless steel. 

Ga.s Eeeders. Chlorine gas is usually fed from a chlorine cylinder equipped with a pressure gauge, reducing valve, regulating valve, feed-rate indicator, and aspirator-type injector for dissolving the chlorine gas in water. The feeder can be manually, or more desirably automatically, controlled utili2ing continuous amperometric or potentiometric measurement of the free chlorine residual. The chlorine solution is normally introduced into the return line to the filter. 

U.S. regulations define this standard as foUows proof spirit shaU be held to be that alcohoHc Hquor which contains one-half its volume of alcohol of a specific gravity of 0.7939 at 15.6°C ie, the figure for proof is always twice the percent alcohol content by volume. For example, 100° proof means 50% alcohol by volume. In the United Kingdom as weU as Canada, proof spirit is such that at 10.6°C alcohol weighs exactiy twelve-thirteenths of the weight of an equal bulk of distiUed water. A proof of 87.7° indicates an alcohol concentration of 50%. A conversion factor of 1.142 can be used to change British proof to U.S. proof.
