Abstract: Provided is a process of enhanced oil recovery from an oil reservoir of an underground formation by using a compound of formula (I) to inhibit the phenomena of retention of anionic surfactants within an oil-bearing reservoir, such as a carbonate or clay reservoir: R—O—(—CH2—CH(—CH3)—O—)m—(—CH2—CH2—O—)n—H, wherein: R is a hydrocarbon-based group comprising from 6 to 40 carbons; m ranges from 0 to 20; n is greater than m and ranges from 5 to 40.

Abstract: The present disclosure relates to the use of at least one compound corresponding to the formula below: R—O-(A)m-H in which: R is a hydrocarbon-based group comprising from 6 to 40 carbon atoms, A is a hexose or pentose unit, m is a non-zero number ranging from 1 to 10, for inhibiting the anionic-surfactant retention phenomena in an oil reservoir, especially in a carbonate-based or argillaceous reservoir.

Preferably the story is based on a singular main character who will lead the audience to the purpose. This allows the audience to understand and connect with the story, thereby facilitating the impact of the narrative presented.

Abstract: This antenna unit comprises an antenna having a radiating front surface, a back surface and a lateral outline having at least one electric field reinforcing region. It is characterized in that it further comprises a device protecting the antenna from lightning, having an internal surface at least partially capping the lateral outline of said antenna by being in electrical contact with said lateral outline, said internal surface covering the or each electric field reinforcing region, said protecting device having a curved external surface opposite said internal surface.

Abstract: The invention relates to the use of at least one compound corresponding to the following formula: R—O—(—CH2-CH(CH3)-O-)m-(—CH2-CH2-0-)u-H where: R is a hydrocarbon-based group comprising from 6 to 40 carbons; m ranges from 0 to 20; n, which is greater than m, ranges from 5 to 40, in order to inhibit the phenomena of retention of anionic surfactants within an oil-bearing reservoir, in particular within a carbonate or clay reservoir.

Abstract: A method of communicating data in a system having a plurality of transmitters each adapted to transmit a radio signal, and a receiver situated at a distance from the transmitters to receive and process the signals transmitted by the transmitters, information for transmission being subdivided into N-bit symbols, the method consisting in: giving a numerical value to each symbol; and compressing the data using a CHIP encoding technique in which the values of the symbols are transposed to an encoded value having x digits in a base B, each digit subsequently being represented in the form of n chips, the base B, the number n of chips, and the number x of digits for an encoded value satisfying the following conditions: B≦2&ngr; and 2N≦B&xgr;  so that the total number of chips x.n representing the coded value is less than 2.N.

Abstract: The coil according to the invention has normal dimensions, but contains a considerable optical fiber length.It is constituted by a main cylindrical support (12) about which is wound a first part (18) of the optical fiber (16), which is to be unwound by pulling. It is constituted by a first concentric, supplementary cylindrical support (14) placed within the main cylindrical support (12), a second part (20) of the optical fiber (16) being wound around said first supplementary support (14), the inner layer of the first part (18) of the optical fiber (16) being directly connected to an outer layer of the second part (20) of the optical fiber (16).
