Abstract: A negative electrode material, a method for producing this material, and to a negative electrode and a lithium-ion battery comprising this material are described. The material comprises an active phase consisting of a material M based on Al, Si, Sn, Sb or a mixture thereof, and a support phase consisting of a material XaYbOc, where: O is an oxygen; Y is a cation with oxidation degree m=3, 4, 5 or 6; X is a cation with oxidation degree d=1, 2, 3, 4 or 5, X ensuring the electroneutrality of XaYbOc; and where: c is such that 2?c?10; b is such that 1?b?4; and a=(2c?bm)/d. An interface of mixed composition exists between the XaYbOc material and the active phase M, the interface consisting of the elements M, X, Y and O.

Abstract: The invention relates to the use of compounds derived from pyrimidinetrione of general formula (I) as acetyl cholinesterase (AChE) inhibitors. The invention also relates to the use of said compounds as insecticides, and to compositions containing the same.

Abstract: The invention relates to a method for exchanging information by inductive coupling or without contact between a reader (2) and a transponder (4), comprising a number of demodulation steps, by the transponder, of a transmission signal coming from the reader, each demodulation step being associated with: a detection of a jump of a parameter of the transmission signal, of a first state to a second state among a set of stable states that the parameter of the transmission signal is capable of adopting; a comparison of the magnitude of the jump and/or of the direction of the jump, at one or more predetermined threshold values; an association with the magnitude of the jump and/or with the direction of the jump, at a value independent of the first state, and; a detection of a stabilization at the second state before another demodulation. The invention also relates to a device for carrying out said method.

Abstract: The use of monomers of active a-amino acids for the preparation of hydrophobic polypeptides in the form of precipitates, whereby the polypeptides result from the polymerization of the aforementioned monomers of active a-amino acids in an aqueous solvent and can be resolubilized in the solvent.

Abstract: According to the invention, a wave, corresponding to a signal s(t) may be temporally inverted by application of a first transformation to lower the central frequency thereof to produce a first set of transformed signals Ki(t) then a second set of transformed signals K?i(t) is produced representing the temporal inversion signal s(?t) and a third transformation is applied to said second set to generate the temporally-inverted signal s(?t)

Abstract: The invention relates to any isolated or synthetic compound and, in particular, to compounds having formula which can: modulate the cell specification of neural stem cells, promote the differentiation and subsequent survival of differentiating glial cells and neurones, and promote the differentiation of oligodendrocyte precursor cells into mature oligodendrocytes. In addition, the inventive compounds can reduce the inflammatory component of diseases that affect the nervous system, for example, by reducing activation of the microglia an/or astrocytes and/or by reducing reactive gliosis. The invention also relates to the methods of preparing such compounds and to the use of same in the preparation of a pharmaceutical composition that is intended for the prevention or treatment of diseases that affect the nervous system. More specifically, the inventive compounds have general formula.

Abstract: A process for continuously coating a strand of continuous carbon filaments by means of a refractory carbide by reactive CVD deposition, which includes the step of causing the strand to travel under mechanical tension with a hermetic enclosure, simultaneously, introducing into the said enclosure a gas mixture consisting of hydrogen and of a volatile compound of an element capable of forming a refractory carbide; and heating the reaction mixture consisting of the strand and the gas mixture so that the formation of the carbide deposit on the filaments takes place by a chemical reaction between the carbon in these filaments and the gas mixture; and the reaction is self-regulated by the diffusion of carbon through the layer of carbide already formed.
