Abstract: A subject of the invention is a process for surfacing or resurfacing a metal part by laser-assisted deposition of a filler material in order to produce an abradable coating of the part, the process being characterized in that the filler material is an iron-based powder comprising vanadium, chromium, nickel, boron, silicon and carbon, in that the laser has an operational wavelength ranging from 900 nm to 1100 nm and in that it comprises the irradiation of the part by a laser beam such that the specific energy (SE) varies from 5 J/mg to 10 J/mg and such that the linear density (LD) varies from 25 mg/mm to 55 mg/mm. Another subject of the invention is the surfaced or resurfaced metal part. Another subject of the invention is a pre-alloy in iron-based powder form, comprising vanadium, chromium, nickel, boron, silicon and carbon.

Abstract: The present invention concerns an in vitro process for diagnosing joint disease in a mammal and/or determining the type of joint disease and/or determining the stage of said disease and/or predicting the course of said disease, comprising the following steps: a) depositing a drop of a synovial fluid sample from said mammal onto a flat substrate made of an inorganic material, such as glass; b) drying the drop deposited in step a); c) measuring at least one parameter indicative of the morphological features of the drop dried in step b), whereby a value for said parameter is obtained, and d) comparing each value measured in step c) with a reference value representative of a reference synovial fluid, characterized in that said parameter is selected from (i) the maximum height (H) of the bead formed on the surface of the drop, (ii) the area of the drop and (iii) the surface profile (Z) of the drop.

Abstract: The present invention relates to a method for dimensioning a turbomachine comprising a casing and a disc to which at least one blade is secured, said disc being rotationally driven by a shaft about a turbomachine axis (z), comprising: —acquisition (E1) of the coordinates (P) of the ends of the leading edge and of the trailing edge of the blade in a frame of reference connected with the disc; —expression (E2) of the coordinates (P?) of the ends of the leading edge and of the trailing edge of the blade in a frame of reference connected with the casing; —calculation (E3) of the distance (g) between the casing and the ends of the leading edge and trailing edge of the blade from the coordinates (P?) expressed in the frame of reference connected with the casing; —calculation (E4) of the contact pressures between the blade and the casing along the end of the blade from the calculated distance (g); —calculation (E5) of the reaction forces and moments resulting from contact between the blade and the casing from the ca

Abstract: A device for the storage of a corneal specimen has means for the reception and entrapment of a corneal specimen, connected to the means for the creation of a pressure gradient with overpressure on the endothelial side and to the preservation medium circulation means in the layouts that present the means for the reception and entrapment of the cornea specimen. The means for the reception and entrapment of the corneal specimen entrap the sclera ciliary zone surrounding the cornea in an airtight manner to delimit a separate endothelial chamber and epithelial chamber in which the preservation medium can circulate with an overpressure in the endothelial chamber; The intermediate component and the endothelial lid comprise inlet and outlet orifices for the preservation medium which are connected to the means for the circulation of the preservation medium and the creation of a pressure gradient between the endothelial chamber and the epithelial chamber with overpressure in the endothelial chamber.
