General Characteristics of the Group

The group is composed of people who are law-abiding aside from their involvement with LSD and marijuana. There have been one or two who have taken narcotics in the past, an occasional charge of petty larceny, one arrest in connection with picketing, one of prostitution and most, as mentioned before, are practicing homosexuals. All except the last of these are not generally characteristic of the group. 

Several general characteristics of the results compiled in Table I are worthy of mention. Compared to the variety of chemicals postulated to be involved in allelopathy (1), few specific compounds have been tested for inhibition of mineral absorption. The most extensively studied compounds are the phenolic acids, probably because of their being ubiquitously found in nature (1). Also, several flavonoids are inhibitory to mineral absorption (Table I). Both of these groups of compounds are often cited as being responsible for allelopathic interactions between plants.

General characteristic of the so-called tetrahedral close packing have been described in 3.9.3.1 where a list of important prototypes of such phases is reported together with an indication of the specific coordination polyhedra. For a few other phases of this group a crystallographic description is given below.

The general characteristics of these groups of powder are summarized in Tables 118-120, according to Roth and Capener [ J ]. Potassium salts arc added (Tables IIS and 119) as flash reducing agents. Lead salts (Table 119) are decomposition moderators which play a role in producing low temperature coefficients of burning propellants and a low exponent n in the expression...
