Abstract: Disclosed is an acoustic resonance spectrometry system for analysing a sample, which includes an optical pump-probe device adapted to generate a pump beam and a probe beam, the pump beam being consisted of a series of ultra-short pump light pulses having a repetition frequency in the spectral domain of the gigahertz, the pump beam being directed towards an optoacoustic transducer to generate a periodic grating of coherent acoustic phonons in the sample, the probe beam being directed towards the sample to form a scattering beam of the probe beam on the grating of phonons, a frequency variation device being adapted to vary the repetition frequency of the pump beam in a spectral range and a photo-detection system configured to measure a scattering signal as a function of the repetition frequency in the spectral range.

Abstract: An analog signals generating device comprises a current pump controlled by a control code generated by a module for calculating the digital code with shaping of noise. The calculation module receives as input a digital signal representative of the analog signal to be generated and comprises at least one quantizer and a quantization error compensating stage. The current pump comprises two groups of at least one electric current generator and two groups of at least one switching means, the switching facilities being controlled by the control signal and causing the electric currents to flow between the electric current generators and the inputs of a differential amplifier exhibiting a predominantly capacitive input impedance and connected in series between the two groups of switching means.

Abstract: A method for depolymerization of lignin includes oxidizing non-phenolic lignin by putting into presence, in at least one solvent, non-phenolic lignin, laccase, redox mediator and a source of oxygen, whereby a mixture including oxidized non-phenolic lignin is obtained, and further includes depolymerization of the oxidized non-phenolic lignin thereby obtained, by adding an oxidizer. The non-phenolic lignin is obtained from phenolic lignin by functionalization of phenol functions of the phenolic lignin.

Abstract: The invention relates to a process for reducing the defectivity of a block copolymer (BCP1) film, the lower surface of which is in contact with a preneutralized surface (N) of a substrate (S) and the upper surface of which is covered by an upper surface neutralization layer (TC) in order to make it possible to obtain an orientation of the nanodomains of the block copolymer (BCP1) perpendicularly to the two lower and upper interfaces, where the upper surface neutralization layer (TC) employed to cover the upper surface of the block copolymer (BCP1) film comprises a second block copolymer (BCP2).

Abstract: A method for the real-time estimation of the total consumption of a fluid, in particular water or gas, distributed from a unit (A) to users (b1, b2 . . . ) via a network of supply pipes (E) with a branch (d1, d2 . . . ), for each user, fitted with a counter (c1, c2 . . . ) of the fluid consumed by the user, which method involves defining cohorts of users having homogeneous behavior with regard to the consumption of fluid; defining, for at least one of these cohorts, a sample of users from the cohort that is statistically sufficient to represent the cohort; fitting only the branches of the users of each sample with a remote reading device (t1, t2, . . . ) for reading the consumption; also fitting remote reading devices to the branches of the users of the other cohorts that have not been sampled; and processing the information provided by the remote reading devices to obtain a real-time value representative of the total consumption of the network.
