In the title compound, C22H21N3O4, the central pyrrolidine ring adopts a C-envelope conformation with a C atom 0.6593 (13) Å displaced from the mean plane formed by the remaining ring atoms. The indoline ring systems (r.m.s. devisations of 0.0356 and 0.0547 Å) are almost perpendicular to the mean plane of the pyrrolidine ring, making dihedral angles of 89.7 (6) and 82.5 (6)°. The acetate group ...

A sequence of four phases has been found for an acetonitrile-solvated co-crystal with 15-crown-5 of the nickel complex [acetonitrilediaqua-κ(1)O-nitrato-κ(2)O-nitratonickel(II)]. The structure could be determined at intervals of ca 10 K in the range 90-273 K because crystals remain single through the three transitions. In phase (I) (T ≥ ca 240 K; P2(1)/m, Z' = ½), there is extensive disorder, w...

For dietary surveillance in the United States, the preferred method for collecting dietary intake data is the 24-hour dietary recall. However, researchers are interested in usual intake (i.e. long-term average daily intake). Researchers are also interested in exploring multiple dietary components collectively to consider dietary patterns, and consumption of these dietary components varies. Some...

Recent studies of adults have found evidence for consolidation effects in the acquisition of novel words (Dumay & Gaskell, 2007), but little is known about whether such effects are found developmentally. In two experiments we familiarized children with novel nonwords (e.g., biscal) and tested their recognition and recall of these items. In Experiment 1 7-year old children were then retested eit...

Let 6n be the symmetric group of n elements and g(n) = max (order of c). We give here some effective bounds for g(n) and P(g(n)) (greatest prime divisor of g(n)). Theoretical proofs are in "Evaluation asymptotique de l'ordre maximum d'un élément du groupe symétrique" (Acta Arith., v. 50, 1988, pp. 221-242). The tools used here are techniques of superior highly composite numbers of Ramanujan and...

Despite the importance of the arts in human life, psychologists still know relatively little about what characterises their experience for the recipient. The current research approaches this problem by studying people's word usage in aesthetics, with a focus on three important art forms: visual art, film, and music. The starting point was a list of 77 words known to be useful to describe aesthe...
