Abstract: Recombinant, alive and metabolically active bacteria including a heterologous prokaryotic biomineralized ferritin. In particular, the inventors have shown that naturally non-magnetic Escherichia coli may be engineered to become magnetic by the expression and the biomineralization of the ferritin of Pyrococcus furiosus. Moreover, the inventors have shown that a fixed number of magnetic E. coli strains keep their magnetic properties through cell division by asymmetrical division. The inventors have also shown that magnetic bacteria according to the invention may be of use in both non-therapeutic and therapeutic uses, such as, e.g., the biosensing of target substance, the depollution of complex environments, the display of antibodies, nanobodies and antigens, the delivery of therapeutic substance to target cells, the targeting and infection of target cells.

Abstract: The method for unloading the inertia wheels of a spacecraft comprising three references axes X, Y, Z, the axis Z corresponding to a pointing direction, consists in inverting the direction of accumulation of the angular momentum in the wheels by automatic rotational flipping of the spacecraft about the axis Z, the pointing direction remaining fixed. The method has application to the field of satellites or of interplanetary probes.

Abstract: The compressive orthosis comprises a leg portion (16) in a compressive knit suitable for delivering degressive therapeutic retention. The compressive knit comprises a net type knit knitted with a weft thread (22) of elastic material, advantageously in combination with at least one background thread (24, 26, 28), likewise in elastic material, and of smaller weight than the weft thread. The assembly forms a deformable array of substantially hexagonal cells (30) which, on being deformed, present greater elastic return force in the horizontal direction (H) than in the vertical direction (V).

Abstract: In a vacuum processing chamber, an exemplary electrical contact assembly between an electrostatic chuck and a voltage source comprises a flexible wire connected at one end to the underside of the electrostatic chuck and at the other end to a conductive socket fixed in the electrode cap. An electrical contacting member which is connected to the voltage source is removably received into the socket so that the electrode cap can be replaced by lifting the electrode cap and socket off of the contacting member which is fixed in the electrode base.
