摘要： The present invention relates to a method and a device for the electrostatic separation of granular mixtures of millimetric or sub-millimetric size, which are composed of non-conductive particles, non-conductive and conductive particles and conductive particles, simultaneously using the electric field E, aerodynamic force and gravity. Said forces are exerted on the particles which are previously charged in an intense electric field E generated by a DC voltage applied to two coaxial cylinders, that constitute electrodes. A mechanical cleaning system detaches the particles from the surface of the electrodes, and facilitates the recovery thereof in a collection system, under the action of cyclone vacuums, in such a way that the cleaning of the electrodes and the collection of the separated particles is continuously performed.

摘要： Inflammation is a prominent feature of ischemia-reperfusion injury (IRI) characterized by leukocyte infiltration and renal tubular injury. However, the signals that initiate these events remain poorly understood. The inventors identify the nuclear alarmin interleukin (IL)-33 as an initiation factor of tissue injury and also as a major amplification factor of the innate immune response triggered by experimental kidney ischemia-reperfusion in mice. In mice lacking IL-33, IRI is reduced, as attested by early decreased tubular cell injury, and by subsequent decreased infiltration of IFN-γ/IL-17A-producing neutrophils and preservation of renal functions. These findings led the inventors to propose that endogenous IFN-33 contributes to kidney IRI by promoting iNKT cell recruitment and cytokine production, resulting in neutrophil infiltration and activation at the injury site. Accordingly, the present invention relates to antagonists of IL-33 for use in methods for preventing ischemia reperfusion injury in an organ.

摘要： Some embodiments are directed to a method for detecting harmonic pollution in an electrical distribution network carrying a three-phase current, including a step of measuring the voltages and strengths of the current, for each of said phases, at a counting point of the network; a step of calculating a first quaternion impedance corresponding to the fundamental frequency of the current; a step of calculating at least one second quaternion impedance corresponding to a harmonic frequency of the current, these impedances being calculated by converting the voltages and strengths in a two-dimensional frame of reference defined according to an angle that is dependent on said frequency in order to provide a system of two vectors of three quantities, ud, uq, uo and id, iq, io, respectively.
