Abstract: A method for manufacturing a turbomachine vane made of composite material, the method including forming, by three-dimensional or multilayer weaving, a fiber blank separated across its thickness into first, second and third parts in two non-interlinked areas present at the longitudinal ends of the fiber blank, the first part located between the second and third parts to which it is connected by weaving outside non-interlinked areas, forming, from the fiber blank, a preform of the vane to be produced, by unfolding and shaping, at each longitudinal end and on either side of the first part, the segments of the second part and the segments of the third part not interlinked with the first part to form preform parts for a platform of the vane, the segments of the first part not interlinked with the segments of the second and third parts extending along the longitudinal axis, and densifying the preform.

Abstract: A method for coating a turbomachine guide vane including a root and a tip, an extrados face and an intrados face connected to one another by a leading edge and a trailing edge, the method including completely covering one of the faces of the vane with a polymer coating of thickness (e1) provided with grooves, removing the grooves from a part of the polymer coating in such a way that the polymer coating includes a grooved zone and a non-grooved zone, coating the non-grooved zone with a coat of paint of thickness (e3) such that the thickness of the coat of paint superimposed on the non-grooved zone is substantially equal to the thickness (e1) of the grooved zone.

Abstract: An apparatus for culturing cells includes a bioreactor including a monolithic structured cell culture bed, which may be fabricated using additive manufacturing techniques, such as for example 3D printing. The bioreactor and monolithic structured cell culture bed may be formed as a unitary structure. The monolithic structured cell culture bed may include regions of varying porosity and/or surface treatments to achieve desired objectives. Related methods are also provided.

Abstract: A method for manufacturing a blade made of composite material for a turbine engine, in particular of an aircraft, the steps of injecting a resin in order to impregnate a fibrous preform woven in three dimensions and polymerizing the resin so as to form the blade that includes an airfoil, one longitudinal end of which is connected to a platform. The platform includes pressure and suction portions connected to the airfoil by a fillet, wherein a separation is formed in the fibrous preform between the pressure and suction portions. The method further includes reinforcing a leading edge of the airfoil; and reinforcing the fillets by integration of a metal reinforcement on at least one part of the pressure and suction portions of the platform and in the separation.

Abstract: The invention relates to a method for breeding insects, comprising growth phases during which the insects are stored in a controlled environment, said growth phases alternating with operating sequences during which at least one specific breeding operation is performed. The method comprises a sequence, referred to as synchronization sequence, during which a batch of insects is sorted and divided into a plurality of size or maturity categories in separate containers, then said containers (31, 32) are grouped together to form basic breeding units (UE) comprising a predefined number of containers (31, 32), a basic breeding unit (UE) comprising only insects of the same category.

Abstract: The present invention relates to a beetle powder containing at least 67% by weight protein and at least 5% by weight chitin, the weight percentages relating to the total weight of the beetle powder. The invention is also directed to a method for preparing the beetle powder and to the uses thereof, in particular in human or animal nutrition.

Abstract: The invention relates to a method for treating insects, comprising the separation of the cuticles from the soft part of the insects, the maturation of the soft part of the insects, followed by the separation of the soft part of the insects into an oil fraction, a solid fraction and an aqueous fraction. The invention further relates to powders, in particular a powder obtainable by the method of treating insects according to the invention, and to the use of these powders in food.

Abstract: A turbomachine vane includes a blading made of composite material with fibrous reinforcement densified by a matrix and an integrated metal leading edge, the blading extending in a longitudinal direction, the leading edge being formed by a metal foil overmolded onto the blading, the foil having a lower wing and an upper wing which extend respectively on the lower and upper faces of the blading while matching an aerodynamic profile of the vane. One of the lower wing and the upper wing has a positioning portion extending in the longitudinal direction, the portion having a flat inner face and an increasing thickness away from the leading edge, and being housed in a correspondingly shaped groove in the blading.

Abstract: The invention relates to a Coleoptera powder for using in the treatment of vibriosis, which particularly affects the white shrimp.

Abstract: The invention relates to a method for the production of chitin and/or chitosan from insects. More specifically, the invention relates to a method for the production of chitin and/or chitosan from insect cuticles, comprising an insect cuticle pressing step, followed by a step involving the enzymatic hydrolysis of the insect cuticles using a proteolytic enzyme, the cuticles having been treated with an oxidising agent prior to the enzymatic hydrolysis.
