Abstract: An upstream part of an air-discharge system for a turbomachine includes: a tube with an upstream end and a downstream end, and an internal tubular structure located inside the tube and configured to form therein a narrowing of its cross section. The internal tubular structure is made in one piece with the tube at the downstream end of the tube and is freely suspended at the upstream end of the tube. A turbomachine with a device for discharging air from the bearing chambers, in which the air is conducted towards the outside of the turbomachine by the air-discharge system is provided. A method for manufacturing the air-discharge system is provided.

Abstract: A device fabricates annular pieces by selectively melting powder. The device includes an inner annular wall and an outer annular wall that are concentric and that define an annular powder deposition zone, and a powder dispenser movable in rotation about an axis of the inner and outer annular walls. The powder dispenser includes a wiper extending between the inner annular wall and the outer annular wall and forming an angle with the radial direction of the inner and outer annular walls.

Abstract: A device (10) for fabricating annular pieces by selectively melting powder, the device comprising an inner annular wall (12) and an outer annular wall (14) that are concentric and that define an annular powder deposition zone (A), and a powder dispenser (16) movable in rotation about the axis (X) of the inner and outer annular walls (12, 14), the powder dispenser (16) including a wiper (18) extending between the inner annular wall (12) and the outer annular wall (14) and forming an angle (?) with the radial direction (R) of the inner and outer annular walls (12, 14).

Abstract: A method for adjusting a predetermined contour of a turbine blade root including a main salient edge defined by a determined interior angle. The method includes: chamfering the main edge of the contour to obtain two auxiliary salient edges, associated interior angles of which are respectively greater than the interior angle of the main edge; and blunting the auxiliary edges obtained to fine-tune the contour of the blade root.

Abstract: A bi-metallic component including a first member of a first metal and a second member of a second metal different than the first metal. The first member includes at least one perforation. The second member is directly cast-in-place about a sheet-like portion of the first member and through the perforation to rigidly secure the first and second members. When used in an automotive vehicle, the second metal of the second member is preferably of aluminum and the first metal of the first member is preferably a high strength steel for spot welding to other steel structures.

Abstract: The present invention relates to a new biomarker for the medicine and the biology of reproduction, in particular for in vitro fertilization (IVF) outcome. It relates to methods for predicting IVF outcome and for selecting the subject for IVF.

Abstract: The invention concerns a method for selecting tumours expressing HLA-G, sensitive to an anticancer treatment, which inhibits or prevents the HLA-G activity of said tumours and the uses thereof. Said method enable to establish either the HLA-G, transcription profile of a solid tumour or the HLA-G expression profile of a solid tumour. The method for establishing the HLA-G transcription profile consists in: (i) drawing a tumoral sample; (ii) extracting the mRNA; (iii) reverse transcription (RT) of said RNA: (iv) successive or simultaneous amplification of the cDNA's obtained in (iii) in the presence of primers specific to each HLA-G isoform and analysing the resulting amplification products, by electrophoresis and/or specific hybridisation and(v) establishing said sample HLA-G transcription profile.

Abstract: The invention concerns the use of a eukaryotic cell coding for at least an HLA-G isoform, to obtain an immunomodulating medicine for inhibiting the activity of killer cells, in particular NK cells and/or for inhibiting the primary allogenic response, in parthologies or situations in which the killer cells are activated or for preparing a medicine to raise the inhibiting function of the isoform(s) expressed by said cells with respect to killer cells, in particular NK cells, in pathologies where these killer cells are inhibited by the molecule of the major histocompatibility complex of I HLA-G classes. The invention also concerns eukaryotic cells expressing at their surface at least an HLA-G isoform and their applications. The invention further concerns transgenic animals specifically expressing at least an HLA-G isoform.
