Abstract: A method is described for the identification of specific tumour antigens by means of the selection of CND display libraries by using sera, characterised in that said selection is accomplished with the phage display technique, and in particular said selection is accomplished by means of the SEREX technique (serological analysis of autologous tumor antigens through the expression of recombinant cDNA). The method according to the invention described herein advantageously combines the SEREX approach with the potency of the phage display technique defined above, at the same time avoiding the drawbacks characteristic of the SEREX technique. The so identified antigens are useful for the preparation of medicaments for the treatment of tumors.

Title: Method and system for three-dimensionally imaging an apical dome of a plant
Inventor: SPENCER PAUL ROGER
IPC: G02B21/00
Filed: 2004-06-17
Abstract: Methods and systems for three-dimensionally imaging an apical dome located at the cotyledon end of a plant embryo are provided. Three-dimensional information of an apical dome can be obtained by scanning the apical dome at varying focal planes along an axis of the embryo, or by using multiple cameras arranged in a confocal manner to image the apical dome. It can also be obtained by irradiating the apical dome with polychromatic light, wherein light beams of multiple wavelengths are focused at multiple focal planes along the axis of the embryo so that the dome's height information can be obtained based on the wavelength of the light precisely focused and reflected at each surface paint of the dome. The three-dimensional information is used to ascertain various morphological features (e.g., size, shape, texture, etc.) of the apical dome, which are in turn used to assess the embryo's germinant vigor.

Abstract: An air flow producer of non-rectangular shape is adapted for installation in a rectangular opening of a drop ceiling. In preferred form, the producer has a circular housing with an open bottom covered with a grill. A fan with a rotary blade assembly is mounted in the housing to produce a downward air flow, and a circular metal band surrounding the rotary blade assembly defines an air discharge zone centered in the grill and an annular air intake zone surrounding the discharge zone. Flow rates are optimized by positioning the band close to the grill. The grill is preferably integrally molded with a rectangular flange that seats in the drop ceiling opening. The flange supports the housing from the framework and closes the opening to prevent the producer from drawing air from the plenum above the drop ceiling.

Abstract: L'invention concerne une pale à utiliser sur une éolienne, et un procédé d'assemblage de profilés stratifiés (3, 5) pour une pale d'éolienne. Un développement vers des pales de plus en plus grandes implique que la technologie de fabrication soit revue et que de nouveaux procédés soient mis en oeuvre, en particulier en ce qui concerne les aspects relatifs à la force et au poids. L'objectif de l'invention est de concevoir une pale fabriquée avec plus de précision, présentant une grande uniformité au niveau de la force, de pale en pale, et qui est plus légère que les pales fabriquées selon la technique antérieure. De nouveaux aspects de l'invention sont caractérisés en ce que la pale comprend une partie poutre (2) qui comporte au moins une première partie (4) et au moins une seconde partie (6); ladite première partie (4) comprenant au moins une partie corps (12) reliée à au moins une face (10) d'ensemble et à au moins une bride de butée (14); ladite seconde partie (6) comprenant au moins une partie corps (18) reliée à au moins une face (16) d'ensemble et à au moins une bride de butée (20). Les parties (4, 6) sont ajustées au moyen d'un système d'ajustement de hauteur (8) et sont reliées l'une à l'autre au niveau des faces (10, 16) d'ensemble. Lesdits profilés stratifiés (3, 5) sont assemblés autour de ladite partie poutre (2) et sont collés contre les brides de butée respectives (14, 20). Ainsi, la hauteur de la partie poutre peut être ajustée en fonction de l'épaisseur desdits profilés stratifiés, de façon que le raccord collé atteigne l'épaisseur désirée. Une certaine quantité de colle est économisée en évitant un dosage supplémentaire, ce qui permet d'obtenir une pale moins onéreuse et plus légère.

Abstract: La présente invention concerne des formes dosifiées et des procédés permettant la libération contrôlée d'oxycodone pendant sur une longue période. Les formes dosifiées à libération prolongée, lorsqu'elles sont administrées une fois par jour, fournissent des concentrations moyennes thérapeutiquement efficaces d'oxycodone dans le plasma à l'état stabilisé. Cette administration de la dose posologique une fois par jour aboutit à une pointe unique de la concentration de l'oxycodone dans le plasma par période de 24 heures, survenant après l'administration. En outre, cette pointe est moins grande que celle qui survient après administration d'oxycodone dans une forme dosifiée à libération immédiate et les autres formes dosifiées à libération prolongée selon l'état actuel de la technique.

Abstract: An anti-tip system is provided for stabilizing a vehicle, such as a power wheelchair, about a pitch axis and relative to a ground plane. The anti-tip system includes at least one anti-tip wheel. The mounting assembly for the anti-tip wheel is configured such that it traverses linearly in a direction toward or away from the ground plane and i s responsive to an acceleration or deceleration of the wheelchair. As the wheelchair accelerate s or decelerates, rotational motion of the drive train assembly is transmitted to a guide subassembly within the mounting to effect translation of the anti-tip wheel. Upward translation of the anti-tip wheel enables the wheelchair to negotiate obstacles, e.g., curbs or steps, while downward translation or force enhances stability when stopping the wheelchair or while moving dow n sloping terrain or surfaces. The anti-tip wheels may be castors and normally contacting the ground during operation.
