Based on results obtained in [15], we construct groups of special S– units for function fields of characteristic p > 0, and show that they satisfy Gras– type Conjectures. We use these results in order to give a new proof of Chinburg’s Ω3–Conjecture on the Galois module structure of the group of S–units, for cyclic extensions of prime degree of function fields. 0. Introduction Let K/k be a finit...

The fat and fatty acid compositions of 28 species of fish and invertebrates (n = 954) from the Scotian Shelf, Georges Bank, and the Gulf of St. Lawrence were determined. Discriminant analysis of the 16 most numerous species (n ≥ 18 each), using 17 major fatty acids, classified species with greater than 98% accuracy and grouped species into three general clusters (gadids, flatfish, and planktivo...
