Abstract: A method for estimating the number of nuclei of a preselected isotope in a molecular species starts with an NMR spectrum of a sample containing said molecular species as a predominant substance, said NMR spectrum comprising a plurality of signal peaks corresponding to said nuclei. By applying inclusion and ordering criteria one obtains a set of ordered signal peaks, the integration of which leads to a set of ordered integrals. Nested outer and inner iteration cycles are carried out, wherein for each cycle a trial number of nuclei is assigned to one of said ordered integrals whilst the other ordered integrals are resealed accordingly and rounded to the next integer value, so as to yield a candidate total number of nuclei. An estimated total number of nuclei is obtained by taking the lowest one from the plurality of candidate total numbers of nuclei that have the highest number of occurrences.

Abstract: La présente invention concerne des procédés et systèmes permettant de traiter un flux de déchets (202) dans un système de retraitement des déchets (204). On a recours à cet effet à un process distinct (206) par lequel on met le flux de déchets (202) en contact avec un gaz riche en gaz détonnant (214) produit sur site par un générateur ad hoc (207). Le fonctionnement de ce générateur (207) fait appel de préférence à l'utilisation d'un signal électrique pulsé appliqué à une série d'électrodes qui sont peu espacées les unes des autres et plongées dans le flux de déchets (202). Ce process permet de dissocier du courant de déchets (202) un composant aqueux, en dégageant en même temps un gaz riche en gaz détonnant (214, 220). Le fonctionnement du générateur de gaz (207) dans le courant de déchets (202) peut donner lieu à un ou plusieurs process distincts (206) de traitement des déchets, et notamment le conditionnement, la stabilisation, l'épaississement et la déshydratation. Une partie au moins du gaz riche en gaz détonnant (220) peut être reprise pour une deuxième utilisation (222) dans le système de retraitement des déchets, et servir de source de combustible pour l'incinération ou la production d'énergie.

Title: Method for producing a moulded article comprising a sprayed polyurethane layer
Inventor: DE WINTER HUGO
IPC: B05D1/34
Filed: 2004-06-23
Granted: 2012-08-21
Abstract: For producing a polyurethane layer by spraying a polyurethane reaction mixture, this mixture is supplied under pressure to a spray nozzle, within the nozzle the reaction mixture is accelerated by passing it through one or more channels having a reduced cross-sectional area, and the accelerated reaction mixture is sprayed, with a predetermined amount of kinetic energy, through a spray opening out of the spray nozzle onto a surface. The channels wherein the reaction mixture is accelerated have a total minimum cross-sectional area of Smm2, S being a value smaller than 1.0, the reaction mixture is sprayed out of the nozzle at a flow rate of between 10 x S and 80 x S g/sec, and, per gram reaction mixture, an amount of 0.05 to 2.5 mmol of a pressurised gas is sprayed together with the reaction mixture through said spray opening out of the nozzle to increase the kinetic energy of the reaction mixture which is sprayed out of the nozzle. By the addition of a pressurised gas to the reaction mixture, a same or even a better spray pattern can be achieved and the reaction mixture can be sprayed at a smaller flow rate.

Abstract: La présente concerne un appareil pour agrandir une rustine tubulaire, conçu pour s'agrandir en rond vers l'extérieur et recouvrir une rustine tubulaire sous-jacente. Un ensemble de réservoir est fixé à une première extrémité du réservoir. L'ensemble de réservoir est muni d'un piston qui divise le trou à l'intérieur en chambre génératrice de gaz et en chambre de liquide. Après avoir été allumé, le dispositif qui crée le gaz produit le gaz, ce qui fait déplacer le piston à l'intérieur du trou et provoque l'injection de liquide à partir de la chambre de liquide dans le réservoir, qui est alors gonflé. Une soupape de protection contre la surpression équipe le dispositif afin d'atténuer la pression dans le réservoir et d'évacuer du liquide du réservoir pour permettre à celui-ci de se dégonfler, si la pression interne atteint un seuil donné.

Title: Hepatitis c virus ns2/3 assay
Inventor: LAMARRE LYNE
IPC: G01N33/566
Filed: 2006-03-16
Granted: 2012-04-10
Abstract: The present invention provides a novel assay for the detection of the NS2/3 cleavage products NS2 or NS3 in the presence of uncleaved NS2/3. In the present invention, following self-cleavage of NS2/3 to generate NS2 and NS3 cleavage products, the sample is incubated with a ligand specific for the recognition of NS2 or NS3 cleavage product in the presence of uncleaved NS2/3. There is provided a method for detecting a NS2/3 autocleavage product in a sample containing NS2/3 protease, the assay comprising: a) subjecting the sample to suitable conditions under which at least a portion of the NS2/3 protease is self-cleaved to yield cleaved NS2 and NS3 products; b) incubating the NS2 and NS3 products with a ligand that can preferentially bind to one of either NS2 or NS3 product over NS2/3 under conditions suitable to afford binding of the ligand to NS2 or NS3; and c) detecting NS2- or NS3-bound ligand produced in step b), whereby the amount of bound ligand detected correlates with the NS2/3 autocleavage activity. The present method is also useful as an assay to screen candidate NS2/3 inhibitor compounds as potential treatment for HCV infection. A further aspect of the present invention concerns ligands selectively recognizing one of the NS2 cleavage product or the NS3 cleavage product with minimal cross- reactivity with the uncleaved NS2/3 and the other cleaved product. Specifically, the present invention provides antibodies that selectively recognize one of cleaved NS2 product or cleaved NS3 product with minimal cross-reactivity with the uncleaved NS2/3 and the other cleaved product.
