In the present paper, we give a short proof of the nuclearity property of a class of CuntzPimsner algebras associated with a HilbertA-bimodule M, whereA is a separable and nuclear C*-algebra. We assume that the left A-action on the bimodule M is given in terms of compact module operators and that M is direct summand of the standard Hilbert module over A.

Products of T.P.D. per cent CO CO, C,H,+C,H, Recent studies of catalysis by supported metal cluster compounds have shown that these systems exhibit novel behaviour. Although diffzcult to characterise, by using a combination of analytical techniques an overall picture can be developed of the cluster nuclearity and the number and type of ligands present. Chemisorption and catalytic studies have b...

Electroglottographic and acoustic data for Catalan three-consonant clusters composed of a wordand syllable-final C1C2 sequence and an underlyingly voiced C3 in wordand syllable-initial position were collected in order to verify whether a regressive voicing assimilation process operates on all obstruents placed at the C2 and C1 sites. Data reveal the presence of low percentages of vocal fold vib...

A new method is introduced to study three-body clusters. Triangular configurations with D 3h point-group symmetry are analyzed. The spectrum, transition form factors and B(Eλ) values of 12 C are investigated. It is concluded that the low-lying spectrum of 12 C can be described by three alpha-particles at the vertices of an equilateral triangle, but not as a rigid structure. Large rotation-vibra...
