During development of the rat central nervous system, neural cell adhesion molecule (NCAM) mRNAs containing in the extracellular domain a 30-bp alternative exon, here named VASE, replace RNAs that lack this exon. The presence of this alternative exon between previously described exons 7 and 8 changes the predicted loop structure of the derived polypeptide from one resembling an immunoglobulin c...

Filtering out traffic with forged source address on routers can significantly improve the security of Internet. However, despite intermittent IP spoofing attacks, existing filtering mechanisms inspect each packet all the time, consuming considerable resource on routers even there is no spoofing at all. This article considers the requirement for a solution performing IP spoofing filtering with a...

Transition curves with monotone curvature profile are widely applied in fair curve design. Advantage of using transition curve is that it can avoid the undesirable curvature extrema. Demonstration of transition curve in designing surface of revolution, particular of vase design can be often seen in literature. For these demonstrations, authors mainly focused on the curvature control of the vase...

Les plantes envahissantes constituent des refuges pour plusieurs espèces de macroinvertébrés aquatiques utilisées dans l’évaluation plans d’eau. Cette étude avait objectif d’évaluer l’importance Azolla pinnata la structuration populations mare aux hippopotames Bala au Burkina Faso. Ainsi, un inventaire a été effectué sur trois types d’habitats que sont A. pinnata, d’autres macrophytes et vase. ...

The effects of pulse treatment with gibberellin A3 (GA3), silveT thiosulfate complex (STS), and with or without sucrose on chlorophyll degTadation and vase life of cut flowers of Narcissus tazetta var. chinensis were investigated. The 20-hr pulsing treatment with STS extended the vase life of cut fiowers of IVL tazetta var. chinensis, Pulse treatments with GA3 delayed degradation of chlorophyll...

l’homme a toujours souffert du caractère impeccable du réel qui, imposant des répressions mentales et sociales, interdit la réalisation des souhaits et des désirs. pourtant il semble que rien ne puisse faire d’obstacles à l’esprit humain lorsqu’il prend la voie du rêve, ce phénomène compliqué et surnaturel. mais quelle est la fonction du rêve quand il entre dans le domaine de la littérature? pe...

The effect of leaf extracts of Psidium guajava and Piper betle on prolonging vase life of cut carnation flowers was studied. "Carola" and "Pallas Orange" carnation flowers, at bud stage, were pulsed 24 hours with a floral preservative. Then, flowers were placed in a vase solution containing sprite and a "germicide" (leaf extracts of P. guajava and P. betle, 8-HQC, or a copper coin). Flowers tre...
