After dominance is established, the dominant male occupies a "preferred" large shelter which becomes a focus of social interactions. Mature, premolt females visit frequently (31,32). For cohabitation and subsequent mating, females in naturalistic aquaria chose the dominant male over subdominants (31). In choice tests females prefer larger dominant males (23). Females make these behavioral decisions both from a distance and at the shelter entrance. Discrimination by females is lost when males are catheterized and can be regained when that male s urine is artificially released near the male (23). Thus, male urine cues for female choice are implied but have not been identified.

In the screw-worm fly (Cochliomyia hominivorax), courtship is generally very brief as a result, bioassays are generally based on male copulation levels (Hammack, 1986). Some CHCs show different levels between the sexes and are thought to be involved in courtship and mating (Pomonis, 1989). Similarly, in Lucilia cuprina, CHCs are thought to play a role in sexual behavior, but decisive evidence has yet to be produced (Emmens, 1981). 

Mueh of the eonfusion existing in replaeement studies is eaused by unamortized values. Some individuals feel that a positive imamortized value represents a loss whieh would be caused by making a replacement. This is not correct because the loss is a result of past mistakes, and the faet that the error was not apparent until a replacement was considered can have no bearing on the conditions existing at the present time. When mating theoretical replacement studies, unamortized values must be considered as due to past errors, and these values are of no significance in the present decision as to whether or not a replacement should be made.

And then there is finally - besides the artificial evolutions of selecting functional nucleic acids for specific interactions with cooperative mates, high-affinic recognitions, and catalytic activities fiom random pools - the evolution of an individual scientific life s work [50], which itself follows decisive stages of the grand process the exploration of early chemical requirements, the development of prebiotic ligand systems, the fixation into the ordered structures of informational inorganic matrix patterns... 

Tribological test results for aqueous solutions of ethoxylated sorbitan esters have been presented in a publication [48], It has been demonstrated that addition to water of such esters as ethoxylated sorbitan monolaurate, ethoxylated sorbitan monostearate, or ethoxylated sorbitan monooleate results in a significant reduction in the coefficient of friction and wear and prevents seizure of mating friction-couple elements. It has been found that the concentration of the additive in water, and not the compound s structure, has the decisive effect on the improvanent in tribological characteristics [48],... 

Obviously, this equilibrium will be disturbed by the introduction of soluble or insoluble substances that remove H+ ions and the red Ni-dimethylgloxi-mate will precipitate. This finding constitutes the basis of a decisive and sensitive test for basic material, using the term basic in its widest sense i.e. material that removes H+ ions.
