- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 13 , A new species of small Barbus is described from the Olifants River System, western Cape Province, South Africa. The new species is restricted to a single tributary complex of the river system and appears closely related to B. calidus. Diagnostic features include pharyngeal teeth formulae, colour pattern, and dorsal and anal fin ray characteristics.

Ligand substitution effects in uranyl ο-hydroxyarylcarbonyl complexes
- Authors: Haigh, John M
- Date: 1974

- Type: text , Article
- Identifier: vital:6372 , http://hdl.handle.net/10962/d1006075
- Description: Twenty-two base adducts of uranyl o-hydroxyarylcarbonyl complexes [UO2L2B] (L = o-hydroxyarylcarbonyl compound, B = H2O, pyridine, pyridine N-oxide) have been prepared. Pure field substituent parameters are used to derive a quantitative order of the electronic effects of the chelate ring substituents. Values of v(U=O) correlate well with these values. Evidence is cited suggesting almost complete non-aromaticity of the chelate ring, and the transmission of the electronic effects of the chelate ring substituent through the uranium atom in the pyridine and pyridine N-oxide base adducts.
