Abstract: A method for verifying whether a queried text of less than 500 characters has been compiled by an author, comprising the following steps: multivariate statistical analysis of the queried text, for example, PCA or PCoA, in order to generate a matrix of coordinates in a space with N dimensions; hierarchical clustering of the points of this space that can be represented by a dendrogram; verification of the author of the queried text on the basis of this clustering.

Abstract: A process for producing a syngas containing CO and H2 from a stream of light hydrocarbons and from combustion flue gases from a cement clinker production unit comprising at least one calcining kiln (300), and a means for discharging the combustion flue gases (500) from the calcining kiln to the outside of said unit, said process comprising the following steps: at least some of the combustion flue gases (70) obtained in said clinker production unit are collected upstream of said means for discharging the combustion flue gases (500); a reaction stream (113) comprising a stream of light hydrocarbons (110) containing methane and the combustion flue gases (70) is prepared; said reaction stream (113) is sent to a tri-reforming reactor (1009) to obtain a syngas (114).

Abstract: The invention relates to a method making it possible to detect style breaks within one or more symbol sequences (20). Said method includes the following steps: automatically slicing at least one so-called “symbol sequence” (2) into a plurality of windows (20A, 20B, . . .

Abstract: A process which allows separation of americium present in an acid aqueous phase or in an organic phase from the other metal elements also found in this phase, by complexation of the americium with a water-soluble ethylenediamine derivative; and a process for selective recovery of americium from an acid aqueous phase containing, in addition to americium, other metal elements, which comprises the application of this separation process.

Abstract: The present invention relates to a method for preparing carboxylic acids, in particular mono- and dicarboxylic acids, by oxidative cleavage of a vicinal diol. According to the invention, said method consists of reacting a vicinal diol of formula I: where: p is an integer comprised between 1 and 6; R1 and R2 are, separately: an alkyl or hydroxyl group having 1 to 12 carbon atoms; a —(CH2)n—C02M group where n, which can be identical or different in R1 and R2, is an integer comprised between 1 and 11 and M is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms or an alkaline cation; or R1 and R2 jointly form an alkylene —(CH2)m- group where m is an integer comprised between 2 and 10, preferably between 2 and 6; with industrial-grade sodium hypochlorite (or bleach), in the absence of an organic solvent and without adding a catalyst, preferably at room temperature. The invention can be used for recycling natural vegetable oils.

Abstract: The invention relates to a process for separating, in an aqueous medium, at least one actinide element from one or more lanthanide elements by using at least one molecule which sequesters the said actinide element to be separated and membrane filtration, the said process successively comprising: a) a step of bringing at least one molecule which sequesters the said actinide element in contact with the aqueous medium, the said molecule not being retained in the non-complexed state by the said membrane and being capable of forming a complex with the actinide element to be separated, comprising the said element and at least two of the said sequestering molecules, which complex is capable of being retained by the membrane; b) a step of passing the aqueous medium over the membrane in order to form a permeate on one side, comprising an aqueous effluent depleted of the said actinide element, and a retentate comprising the said complex.

Abstract: A process for the separation and purification of hafnium and zirconium.

Abstract: A method for separating zirconium and hafnium from a mixture of ZrCl4 and HfCl4 containing 3 wt. % or less of Hf based on Zr+Hf, the method includes the following steps: 1) hydrolyzing a mixture of ZrCl4 and HfCl4 in an aqueous solution of strong inorganic acid, so as to form an aqueous solution having 7 to 12 moles of acid per liter; 2) passing the solution obtained at step 1) in an anion exchanging resin; 3) optionally eluting a fraction of said aqueous solution having 7 to 12 moles of acid per liter, enriched in hafnium; 4) removing the resin of the acid solution containing Zr and Hf; 5) passing in the resin an aqueous solution to detach the zirconium compounds fixed to the resin, and recovering a zirconium-enriched fraction.

Abstract: A process for denitrogenation of hydrocarbonated compounds containing basic and/or neutral nitrogenous hydrocarbonated compounds characterized by the fact that the hydrocarbonated compounds are placed in contact with a polymeric material including at least one polymer P obtained from at least one non-styrenic monomer A with at least one polar function generating hydrogen bonds with the nitrogenous hydrocarbonated compounds.

Abstract: A reusable coupling adaptable to the ends of a tube, the coupling including a nipple (2) having a toothed end (7) designed to be inserted into the tube (1), its inside diameter corresponding approximately to the inside diameter of the tube, the nipple having an annular surface external to the tube. A peripheral ferrule (4) is mounted around the tube (1) and imprisons the tube in engagement with the toothed part (7) of the nipple (2). The ferrule (4) includes an inward annulus (5) which fits into a peripheral groove (6) on the surface of the nipple, while a seal (8) is provided within the groove to be contacted by the annulus (5). The ferrule (4) is radially compressible and is immobilized and fixed to the periphery of the tube (1) by a connection assembly made up of two connectable parts (9, 10) mounted around the end of the tube on either side of the ferrule, and which compresses the ferrule after it has been fitted on the tube.

Abstract: A hollow milling tool (1) for the production of substantially hollow cylindrical depressions in human or animal tissue, in particular for the production of tissue pillars which are removed at a harvest location, transported to a defect location and implanted there, has teeth (2) for the ablation of tissue which are arranged at the distal end of the milling tool at the end side. Furthermore, the milling tool has passages for transporting a cooling fluid to a cooling region of the milling tool lying near the distal end during the ablation of tissue.
