The ease with which acrylic monomers may polymerise with each other and with other monomers has led to a host of compositions, frequently of undisclosed nature, being offered for use as moulding materials, casting resins, coating resins, finishing agents and in other applications. 

The queen is usually reproductively dominant within the colony and uses chemical cues as both primer and releaser pheromones to suppress the production or fecundity of other sexuals, inhibit reproduction by worker castes, modulate reproductive behaviors (e.g., inhibit swarming and orient swarms), attract males, regulate worker tasks and worker ontogeny, and produce host repellents in slave-making species. Considering the importance of queen semiochemicals in social hymenoptera, few queen pheromones have been chemically identified. The queens of most social hymenopteran colonies are attractive to workers, allowing them to be properly tended as well as to facilitate the dissemination of other pheromone cues. However, the retinue pheromone has been chemically identified in very few species. In the 1980s, queen pheromone components were identified in the fire ant, Solenopsis invicta [91,92], and in the Pharaoh s ant, Monomoriumpharaonis [93]. 

Spectral experiments on incorporation of sodium alkylsulfonates as guest molecules into the host bilayer assembly strongly suggest formation of the void space expected in the structural model I. Cast films of 1 1 mixture of CsAzoCioN+Br and sodium n-butylsulfonate (kmax = 303 nm) or sodium propylsulfonate (kmax = 302 nm) showed a similar absorption spectrum of pure C5AzoCjoN+Br cast film (kmax = 301 nm). Longer guest molecules sodium n-pentylsulfonate (kmax = 326 nm), n-hexylsulfonate (kmax = 329 nm), and n-heptylsulfonate...

One of these is of course the sheer difficulty of finding a suitable host who will be tolerant of an action learner and supply a project for him or her to work on. Working in a host organization may also mean - though not necessarily -casting oneself in the role of external consultant who is confined to making recommendations for others to act on. The limitations of this for management development have already been commented upon. 

The Baltimore Museum of Art hosts the Cone collection including many works by Matisse. Bronze sculptures by Matisse were cast using different methods (lost wax and sand cast) and in different foundries. Ann Boulton of the Baltimore Museum of Art initiated a project aimed at determining whether or not different compositions of Matisse bronze sculptures could be correlated to different manufacturing techniques or locations. The project started while the author was a post-doctoral fellow at the Smithsonian Center for Materials Research and Education, now Museum Conservation Institute, and involved other analytical techniques (12). The results presented here were obtained at the Field Museum of Natural History. 

In that day, saith the Lord of hosts, "shall ye call every man his neighbor under the vine and fig tree." THAT DAY is verily at hand, though it SEEMS to be very far off, when we contemplate the millions that are engaged in slaughtering each other. But these are the "terra damnata," the refuse at the bottom of the still, utterly without the spirit of love and truth, the spirit of constructive altruism, and must first be "cast into outer darkness, where there is weeping and wailing and gnashing of teeth."...
