The title complex, [Fe(C(36)H(36)N(4)O(4))Cl], shows a domed structure with a slightly distorted trapezoidpyramidal core, in which the perpendicular displacements of the Fe(III) atom from the mean pyrrole N(4) plane are 0.418 (3) and 0.465 (3) Å for the two crystallographically independent mol-ecules.

Let G be a graph of order n. A graph G is called pancyclic if it contains a cycle of length k for every 36 k6 n, and it is called vertex pancyclic if every vertex is contained in a cycle of length k for every 36 k6 n. In this paper, we shall present di0erent su1cient conditions for graphs to be vertex pancyclic. ? 2002 Elsevier Science B.V. All rights reserved.

We show that every [n, k, d]3 code with diversity (Φ0, Φ1), 3 ≤ k ≤ 5, gcd(d, 3) = 1, is (2, 1)-extendable except for the case (Φ0, Φ1) = (40, 36) for k = 5, and that an [n, 5, d]3 code with diversity (40, 36), gcd(d, 3) = 1, is (2, 1)-extendable if Ad ≤ 50. Geometric conditions for the (2, 1)-extendability of not necessarily extendable [n, k, d]3 codes for k = 5, 6 are also given.

One major motivation for nominalism, at least according to Hartry Field, is the desirability of intrinsic explanations: explanations that don’t invoke objects that are causally irrelevant to the phenomena being explained. There is something right about the search for such explanations. But that search must be carefully implemented. Nothing is gained if, to avoid a certain class of objects, one ...

SAlthough different theoretical models are complementary, functional models in general, andSystemic Functional Linguistics in particular lend themselves to the analysis of text. This is so atthe level of register, in terms of Field, Tenor and Mode, as well as at the level of semantics interms of ideational, interpersonal and textual metafunction. This paper will consider two...
