Conditions necessary for sporulation in one species do not necessarily apply to another. The subject appears to be in such a state of confusion that it is impossible to discuss sporulation in terms of generalities. 

The preparation of [5]rotane 81 (pentaspiro[2.0,2.0.2.0.2.0.2.0]pentadeeane), again includes one step of carbene addition, by the Simmons-Smith reaction, to 13-methyle-ne-tetraspiro[2.0.2.0,2.0.2.1]tridecane 8026). A full paper on the subject appeared later 27 >. 

The number of 13C NMR studies on metal carbonyls has greately increased over the last few years as shown by the presently available data on tetranuclear carbonyls (Table 11) compared with that available in 1974 when the last review232 on this subject appeared and contained only two references to tetranuclear clusters. 

Having observed a decrease in appetite and thirst when testing BZ, we decided to measured caloric and fluid intake more precisely in the EA 3443 series. At the incapacitating dose, calories ingested and fluid consumed both dropped by about 40%. Sleep duration, also measured, increased at the lower doses but seemed to drop precipitously at the incapacitating dose. This seeming insomnia, however, was illusory. Delirious subjects appeared physically awake, but were asleep in terms of brain electrical activity - the so-called pseudowakeful state. ... 

Students often find pharmacokinetics difficult. Two of the reasons are that a very formal writing style together with many equations make the subject appear much more difficult than it is. In this chapter we have deliberately adopted an informal style and aimed to keep key concepts as simple as possible. We hope we have succeeded and that you will And the chapter helpful as you prepare to become good prescribers. 

Apart from nonspecific symptoms, such as pain at the Injection site, subjects appeared unaffected subjectively and objectively. In one sense, this series of experiments provides some index of placebo responsiveness—minimal. Many subjects commented (as recorded In the charts) that they generally enjoyed the experiments, thought well of the staff support, and, In general, had few complaints other than about the food. 

Although DM has greater acute toxicity to the respiratory tract than CS and CN, Edgewood subjects appeared to recover shortly after exposure. Given the available information on DM and the short low-dose exposures, It Is Impossible to predict whether Edgewood subjects exposed to DM will suffer any longterm effects of the exposure. 

The mechanism for the polymerization probably fits the general pattern of electrophilic attack by the initiator on the carbonyl oxygen atom for the initiation step, with propagation taking place by attack of the electron deficient C-4 of the last unit of the growing chain on the carbonyl group of a monomer molecule. Certain modifications of this general mechanism are apparently observed with specific catalysts, and the subject appears to need further study. 

Atmospheric vapor. Vapor results from pesticide volatilization during spray release, vaporization from leaf deposits, and, over a longer time period, desorption from the soil and litter of the forest floor. Several reviews of this subject appear elsewhere in this Symposium volume. 

So, without guide or compass, without so much as a friendly hint from a living soul, we set out to find the lost trail in a veritable jungle, the traces of which were apparently hopelessly obliterated. To follow other commentators seemed of little avail. One of the earliest of these, and about the only one printed in this country until our own works on the subject appeared, was a book by E. A. Hitchcock, entitled "Alchemy and the Alchemists," published about 1850. 

Continuing the earlier work of Russian chemists, Zelinskii has concerned himself with dehydrogenation of cyclic compounds since 1911. The contributions of Zelinskii and his students have been reviewed a number of times in the Russian literature and several articles on the subject appeared on the occasion of his 90th birthday in 1951 (155,351). 

Safety and its practice are of the utmost importance for corrosion personnel, both in the corrosion laboratory and plant operations. The subject appears mundane at first glance although in realistic terms it is of paramount importance when factors such as loss of life due to accidents by nonadherence of personnel to prescribed safety procedures in laboratories and industrial operations are considered. The safety procedures used in the laboratory and field operation are intended to be preventive measures to avoid the occurrence of accidents, which may result in injury or loss of life, depending upon the nature of the accident. 

Historians of ideas soon learn—to their dismay—that their subject appears to be mathematically dense between any two people who wrote on the matter there appears to be another. 

In our balance studies O) we found that while mean zinc balance of a group of subjects appears to provide meaningful results, data of Individual subjects Is less reliable. While mean zinc balance In one study of elderly men consuming 15 mg of zinc per day was 0.1 mg/day. Individual subjects appeared to retain or lose as much as 1.8 mg of zinc dally. 

Tphe best approach to this subject appears to be a consideration of the source—or mode of introduction—of pesticides in our environment, followed by a discussion of their occurrence. We direct our attention, then, to a general survey of the sources of pesticide contamination.
