<i>Aralia fragrans</i> (D. Don) Jebb & J. Wen, une nouvelle combinaison dans les Araliaceae.
No full textHedera fragrans D. Don et Aralia leschenaultii (DC.) J. Wen sont identiques, le premier étant nomenclaturalement prioritaire. Une nouvelle combinaison, Aralia fragrans, est ainsi nécessaire. Aralia fragrans appartient à Aralia sect. Pentapanax et est largement distribué en Asie, y compris le Bengladesh, Bhutan, la Chine (Yunnan), l\u27Inde, le Nepal, le Sri Lanka, la Thailande du nord (Chiang Mai), et le Nord Vietnam (Lao Cai). Cette espèce semble très affine de Aralia kingdon-wardii J. Wen, Lowry & Esser.Hedera fragrans D. Don and Aralia leschenaultii (DC.) J. Wen are identical, but the former has nomenclatural priority.

Experimental investigation on the flow condensation of R450A, R515B, and R1234ze(E) in a 7.0 mm OD micro-fin tube
No full textThe flow condensation of R1234ze(E), R450A, and R515B was conducted in a 6.14 mm inner diameter micro-fin tube. The fin height is 0.18 mm and the fin number is 50. The helix angle is 18° and the area enhancement factor is 1.63. During the experimental tests, the saturation temperature is 30 and 40 °C. The mass fluxes range from 50 to 400 kg m-2 s-1. The vapor qualities are between 0.1 and 0.96. The heat transfer coefficients and frictional pressure gradients of the three refrigerants were compared with each other. The experimental heat transfer coefficient increases with vapor quality and mass velocity, except at high vapor quality, where a higher mass velocity does not imply a higher heat transfer coefficient, probably due to the liquid film thickness distribution. Generally speaking, R450A presents slightly higher heat transfer coefficients at high mass fluxes and smaller pressure gradients, whereas R515B shows lower heat transfer coefficients and pressure drops very close to those of R1234ze(E). Moreover, some models of the heat transfer coefficient and pressure gradient specifically developed for micro-fin tubes were chosen to explore their feasibility for the new refrigerants and tube. Cavallini et al.’s model shows the best agreement for the heat transfer coefficient, and Diani et al.’s model shows the best agreement for the frictional pressure gradient
A deficiency in the region homologous to human 17q21.33-q23.2 causes heart defects in mice
No full textSeveral constitutional chromosomal rearrangements occur on human chromosome 17. Patients who carry constitutional deletions of 17q21.3-q24 exhibit distinct phenotypic features. Within the deletion interval, there is a genomic segment that is bounded by the myeloperoxidase and homeobox B1 genes. This genomic segment is syntenically conserved on mouse chromosome 11 and is bounded by the mouse homologs of the same genes (Mpo and HoxB1). To attain functional information about this syntenic segment in mice, we have generated a 6.9-Mb deletion [Df(11)18], the reciprocal duplication [Dp(11)18] between Mpo and Chad (the chondroadherin gene), and a 1.8-Mb deletion between Chad and HoxB1. Phenotypic analyses of the mutant mouse lines showed that the Dp(11)18/Dp(11)18 genotype was responsible for embryonic or adolescent lethality, whereas the Df(11)18/+ genotype was responsible for heart defects. The cardiovascular phenotype of the Df(11)18/+ fetuses was similar to those of patients who carried the deletions of 17q21.3-q24. Since heart defects were not detectable in Df(11)18/Dp(11)18 mice, the haplo-insufficiency of one or more genes located between Mpo and Chad may be responsible for the abnormal cardiovascular phenotype. Therefore, we have identified a new dosage-sensitive genomic region that may be critical for normal heart development in both mice and humans
