Abstract: A nozzle (302) comprised of a thin, flexible membrane material having a plurality of pores is disclosed. In one embodiment, the pores have an unflexed exit aperture diameter in the range of about 0.5 microns to about 2 microns (preferably about 1 micron), and are positioned substantially uniformly in the material, preferably about 50 microns apart. The nozzle (302) preferably has a conical or trumpet shaped cross section. In another aspect of the invention, the exit aperture of the nozzle (302) is surrounded by an elevated area (81) protruding above the substantially planar exit side of the membrane in order to prevent intrusion of liquid back into the nozzle (302). The nozzle (302) can be used to form an aerosol containing a pharmaceutical composition from the exit side (38) of the nozzle (302) upon forcible application of the composition to the entrance side of the nozzle (302). This aerosol can be used to administer the pharmaceutical composition, for example, to the eye or to a selected portion of the respiratory tract. The nozzle (302) is preferably a component of a container (1) which holds a formulation (5) of drug.

Filed: 2001-06-08
Abstract: L'invention concerne un procédé visant à protéger l'acier au carbone et l'acier inoxydable, et notamment l'acier réfractaire inoxydable, contre le cokage et la corrosion à températures élevées dans des environnements corrosifs, p. ex. pendant la production d'éthylène par pyrolyse d'hydrocarbures ou la réduction de minerais oxydés. Le procédé consiste à enduire l'acier d'un revêtement de MCrAlX ou de MCrAlXT, M représentant nickel, cobalt, fer ou un mélange de ceux-ci, X représentant yttrium, hafnium, zirconium, lanthanum, scandium ou une combinaison de ceux-ci, et T représentant silicium, tantale, titane, platine, palladium, rhénium, molybdène, tungstène, niobium ou une combinaison de ceux-ci. Le revêtement et le substrat sont de préférence traités thermiquement à une température comprise entre 1000 et 1200  DEG C environ pendant au moins 10 minutes environ, de préférence entre 20 minutes et 24 heures environ, cette durée étant suffisante pour obtenir une liaison métallurgique entre le revêtement et le substrat, et former une microstructure à phases multiples. Le revêtement est de préférence aluminié par dépôt sur celui-ci d'une couche d'aluminium, et oxydation du revêtement résultant à une température supérieure à 1000  DEG C environ pendant une durée suffisante pour former une couche superficielle d'alumine. Une couche intermédiaire contenant de l'aluminium peut être déposée directement sur le substrat avant le dépôt du revêtement, cette couche étant traitée thermiquement avec le revêtement pour former une couche intermédiaire de protection entre le substrat d'acier inoxydable et le revêtement, destinée à disperser la formation de nitrure à la surface de séparation substrat/revêtement. De plus, le revêtement peut être déposé sur le substrat et former une liaison métallurgique avec celui-ci par dépôt à arc transféré de plasma de poudre atomisée de MCrAlXT, ce qui permet d'éviter un traitement thermique séparé. Dans une autre forme de réalisation, une composition de mélange de poudres destinée à produire un alliage MCrAlXT voulu peut être appliquée au substrat.

Title: Use of the combing process for the identification of dna origins of replication
Inventor: HYRIEN OLIVIER
IPC: C12Q1/6804
Filed: 2000-05-29
Abstract: Eukaryotic genomes are duplicated by the activation of multiple bidirectional origins of replication. The replication programs of these cells depend on the temporal and spatial organisation of replication origins throughout the genome. To investigate the replication program in a higher eukaryote, we employed a technique called molecular combing. This technique allows for a quantitative analysis of DNA replication on a genome wide basis. As a model system, Xenopus laevis sperm chromatin were differentially labelled at successive time points after the beginning of DNA synthesis.  Genomic DNA was then extracted and combed on a glass surface. Direct measurements made on the labelled DNA provided a comprehensive analysis of the spatial and temporal organisation of the X. leavis early embryo replication program and revealed that the number of replication origins activated per kilobase increases throughout the period of DNA synthesis.
