A more recent paper by Rycroft and Cole (2001) described a study of Plagiochila rutilans Lindenb. From Bolivia, Brazil, and Costa Rica (all freshly collected) and Cuba and Ecuador (dried specimens). Material from Cuba had been described by Huneck et al. (1984) to contain, among other compounds, l-(3,4-dihydroxy-5-methoxyphenyl)-3-methylbut-2-ene. In the recent paper, Rycroft and Cole present evidence that the correct structure of the compound is l-(2,5-dihydroxy-3-methoxyphenyl)-3-methylbut-2-ene, which can also be called 2-methoxy-6-prenylhydroquinone. The corresponding quinone was also observed as a minor constituent.

In total, 185 substances were found in the wing-sac liquid of male S. bilineata from a Costa Rican population. For a more detailed analysis the relative peak area of thirteen focus compounds was compared (Table 14.1). Of these nine were male-specific substances (indole, indol-3-carboxaldehyde, indole-3-carboxylic acid, 2-aminoacetophenon, anthranilic acid, SHJOH-dipyrrolofl -aT -dJpyrazine-5,10-dione (pyrocoll), indolo[2,l-b]quinazoline-6,12-dione (tryptanthrin), 2,6,10-trimethyl-3-oxo-6,10-dodecadienolide, and a compound C15H24O2 of unknown structure), three were fatty acids (tetradecanoic acid, hexadecanoic acid, and octadecanoic acid), and one a steroid (cholesterol). On average, the cumulative peak area of these substances made up 62.5 20.7% of the whole chromatogram area.

Currently we know very little about naturally occurring tetrodotoxin analogs or precursors. Chiriquitoxin, isolated along with tetrodotoxin from the Costa Rican frog Atelopus chiriquiensis (21,22), is known to possess the same basic skeleton as tetrodotoxin but differs by an uncharacterized substituent at C-6, as shown in the structure below. It also was shown, based on isolation experiments, that...

Zolpidem is an imidazopyridine, with a chemical structure of N,N,6-trimethyl-2-(4-methylphenyl)-imidazo [ 1,2-alpha] -pyridine-3-acetamine hemitartrate (Salva and Costa, 1995). This nonbenzodiazepine sedative hypnotic was first released in Europe, and then introduced in the United States in 1993 (Hobbs et ah, 1996). Zolpidem has a strong sedative effect that seems to preclude its use as an anxiolytic. It has only weak anticonvulsant effects (Salva and Costa, 1995 Hobbs et ah, 1996). 

For example, several redshift surveys, such as those performed by Huchra et al. [28], Giovanelli et al. [29], De Lapparent et al. [30], Broadhurst et al. [317], Da Costa et al. [32] and Vettolani et al. [33], have discovered massive structures such as sheets, filaments, superclusters, and voids, and show that large structures are common features of the observable universe the most significant conclusion to be drawn from all of these surveys is that the scale of the largest inhomogeneities observed is comparable with the spatial extent of the surveys themselves. 

Another important consideration is the development of an efficient control strategy, because this minimizes the costs by maintaining the process in its optimal conditions. Costa et al. (5) determined the best control structures and studied the control of the process proposed by Silva et al. (3) using a linear predictive controller. Later, a nonlinear predictive controller using FLNs as the internal model was developed and implemented with the same process with promising results (6).
