Ostrich

Closely related to the crown ether adducts are the two intramolecular arenediazonium ion-crown ether compounds 11.6 and 11.7 which were synthesized by Gokel s group (Beadle et al., 1984b). Infrared and lH NMR spectra are consistent with the insertion of the diazonio group into the 21-crown-7 cavity. The complex 11.6 can therefore be described not in an anthropomorphic, but in a zoomorphic way, as an ostrich complex reflecting the common belief that an ostrich hides its head in a hole when endangered. For the complex 11.7 the spectra correspond to... 

A typical polar (and non-radical) reaction contrasts with a typical radical (and not very polar) reaction in the ways listed in Table XIII. Each statement of Table XIII has known or easily foreseeable exceptions, and some of the statements may not be true even for a majority of radical or non-radical reactions. Perhaps Stefansson would call these propositions Standard Errors. 486 The Typical Radical Reaction is a useful concept whose status is something like that of the Literary Ostrich486 and other fauna of strictly metaphorical habitat but very well-known behavior. Real ostriches are useless for metaphorical purposes and no one expects them to behave like literary ostriches.

Most psychiatric patients do not meet the criteria of one particular disorder as presently defined, but show signs and symptoms of a multitude of disorders, or rather they display a patchwork of parts of different disorders. This situation faces biological psychiatry with insurmountable problems in determining which of the disorders in a given patient is the behavioral correlate of a particular biological disturbance. The hierarchical principle as applied in the later DSM editions—albeit inconsistently— provides no more than an ostrich solution. The problems of comorbidity do not disappear by concealing them.

In rodents, some of the urinary metabolites were identified as dienestrol, and as hydroxy- and methoxy-derivatives of dienestrol and diethylstilbestrol. When dietiiylstilbestrol was given orally to ostriches, parent compound and the metabolite dienestrol could be detected in urine (44). Diethylstilbestrol was rapidly excreted, its concentration being above 2 ppb for only 4 days although it could be detected by 18 days. The concentration of dienestrol was just above 2 ppb for 1 day only and could be detected for 3 days only. 

During 1997-1998 beef, sheep, and pork were the main commodities monitored, but horse, deer, emu, ostrich, poultry, and eggs were also covered. Over 20,000 samples were collected on which about 29,000 chemical analyses were conducted during 1997. Drug residues were not detected in any of the horse. 

Three classes of anthelminthics were also monitored macrocyclic lactones, benzimidazoles, and levamisole. Samples were taken from cattle, sheep, pigs, and ostriches. Only 2 of 2613 samples contained residues above the MRL. These were for fenbendazole in a cattle sample and avermectin in a sheep sample. 

The second approach to treating nondynamical correlation has an air of the ostrich about it ignore the spin symmetry of the wave function and use unrestricted Haxtree-Fock (UHF) theory as the single configuration description [7]. Since the UHF wave function comprises one spin-orbital for each electron, a molecular UHF wave function should dissociate to atomic UHF wave functions, for example. This is certainly not the case for spin-restricted Hartree-Fock (RHF) molecules and atoms in general. And there is an attractive simplicity about UHF — no active orbitals to identify, and so forth. However, where nondynamical correlation would be important in an RHF-based treatment, the UHF method will suffer from severe spin-contamination, while where nondynamical correlation is not important the RHF solution may be lower in energy than any broken-symmetry UHF solution, so potential curves and surfaces may have steps or kinks where the spin symmetry is broken in the UHF treatment.

The emu (Dromaius novaehollandiae Fig. 6.3) and ostrich (Struthio camelus) are ratites, i.e. flightless birds with broad, rounded breast plates missing the keel to which the breast or flight muscles attach. Both are now being farmed in several countries.
