The F-factors of 5.0 and 8.0 are cousei vative in the opinion of the researcher who performed the experiments (private communication from E. I. dll Pout de Nemours Co., Inc., to the DIERS Project).

The spreading pressure q> of films of hexadecyl alcohol (cetyl alcohol) on water has been measured by Adam (Proc. Roy. Soc. A 1922, 101, 452). In one experiment (private communication from Adam to Wolfenden) the film contained 5.20 x 10 mg of hexadecyl alcohol. The width of the trough was 14.0 cm and the effective width of the floating barrier was 13.8 cm. The values of the force on the float for various lengths of film are given in table 1.

Shimamori and Hatano (1976) describe a Febetron-injected microwave cavity apparatus for measuring electron concentration following pulse irradiation. Its application to thermalization in Ar and CH4 is similar to the method of Warman and Sauer (1975). In a related experiment, Hatano et al. (private communication) measure the electron collision frequency directly. 

The submitters and the checkers prepared the sodium ethoxide in the conventional manner. However, sodium eth-oxide and sodium methoxide are very conveniently prepared by the inverse procedure, as described by Tishler in Fieser, Experiments in Organic Chemistry, 2nd Ed., 1941, D. C. Heath and Company, New York, p. 385 (bottom) The metal is placed in the flask, and the alcohol is added through the condenser at such a rate that rapid refluxing is maintained. It is necessary, as a precautionary measure, to clamp the flask and not to trust to the friction between a rubber stopper and the flask to hold the flask in place. When this precaution is taken, a cooling bath may be used with safety. It is necessary to cool the flask the metal must not be allowed to melt, as this will result in the formation of one large mass with a greatly decreased metallic surface. (Private communication, C. F. H. Allen.)... 

In a private communication, Prof. Krief has informed us that subsequent experiments do not support his early claim (ref. 70) of higher reactivity for the selenium analogue... 

Dr. E. Lee, Lawrence Radiation Laboratory (private communication). The referee has pointed out to us that Mader experimented with a positive AH/ in the course of his BKW studies. While using a positive AHj for carbon was a help in calculating P and D, it caused troubles in calculations involving the isentropic expansion of the detonation products, perhaps because it was not allowed to change during this process. 

Colebum now feels that his results for EDNA hill out of line with most of his other measurements, and he attributes this to difficulties in reading the photographic records in this set of experiments. N. L. Colebum, U.S. Naval Ordnance Laboratory (private communication).

The result obtained here agrees with experiment. Thus, in Belyaev s experiments [11] at the boiling temperature of nitroglycol m (Tcb) = 0.65 mm/ sec.19 The lowest measured velocity at 0°C was 0.26 mm/sec (Andreev), i.e., 40% of u (Tcb). According to a private communication by Belyaev, at lower temperatures steady combustion was not observable. 

After these initial experiments, carbosilane dendrimers with a similar binding motif in the core have been synthesized and their properties have been investigated [27] (van Heerbeek et al., private communications). It was...

Since the apparent rate constant is sensitive to UFoo in experiments in which reactant species are adsorbed, care must be taken to hold UFoo constant. Sediment is commonly diluted to facilitate handling in incubation experiments (A. Zehnder, Univ. Wisconsin, privation communication, 1978). Such dilution could result in an increase in the apparent reaction rate as shown by the above example. Incubation experiments are also done using flooded soils (11) and if reactants in such experiments adsorb, UFoo must be held constant. Thus, comparison of experiments done with different sediments or soils or with varying ratios of water to solids should be interpreted with care. 

Harlow and Nakayama (H2), noting that the length scale will be used to determine the dissipation, proposed a closure model for the exact differential equation for S> derivable from the Navier-Stokes equations. They experimented with the use of this equation in MTEN closures. The Los Alamos group (private communication) has now abandoned the MTE closure in favor of MRS closures, which also use the SD equation for inference of length scales [see Eq. (61) ]. They refer to the SD equation as a dissipation equation, which as we have noted is not strictly correct. 

When cystine is irradiated at pH values below 5 in the presence of air and water, S—S fission predominates. Oxides such as CyS02SCy may be formed as intermediates, but the products isolated are mainly compounds such as cysteic acid, CySOsH. Alanine, serine, and glycine, produced in quantity in the absence of air, were formed only in minute amounts in its presence. Under all conditions of irradiation CyS02SH and CySSSCy were formed. When cystine was irradiated in the dry state cysteine, alanine, and lanthionine were formed. The results of irradiation experiments on cystine solutions are summarized in Table XXV. Savige (private communication, 1964) considers that products obtained by irradiation of cystine may arise by the following mechanisms ... 

The only datum wc have found contradicting this conclusion is also given by Kuhn (1162) for HCl-glycol solutions. Kuhn has indicated in a private communication that these experi naents are probably unreliable. 

After we finished the manuscript we learned of recent experiments by X. Shi et ai on sound attenuation (to be published) and by R. Yu et ai on thermal conductivity (private communication). Their results indicate that there is a frequency-dependent glassy behavior at low temperature, in agreement with our predictions. 

A new experiment at this frequency gives 19.57 (D.P. Shelton, private communication, 1992).
