Abstract: The reflectarray comprises an array of patch elements (10-13). Each patch element has a cut ring shape formed of a conductive ring with at least one crossing gap. The outer diameter and inner diameter and crossing gap are adjusted so that a phase shift ? defined by the following relations is different from zero: ?(Eox)=?(Eix)+? (1) ?(Eoy)=?(Eiy)+?+? (2) where: ??(Eox) and ?(Eoy) are the phases of the orthogonal components and of the reflected wave, respectively, ??(Eix) and ?(Eiy) are the phases of orthogonal components and of the incident wave, respectively, ?? is a phase angle.

Abstract: The invention relates to a mobile communicating object (A) belonging to a communications network and comprising processing invention, when a communication has been established with another communicating object (S) belonging to the network, the aforementioned processing means generate a repeater (Fi) at each site (Hi) through which they pass. Moreover, when the repeater is generated, the processing means associate a timing counter (CTF) therewith and configure said repeater such that: (i) it can store an identifier that is representative of the location of the next repeater (F(i+1)) or site (H(i+1)) in the chain of repeaters to which it belongs; and (ii) at the end of a selected duration of time, it transmits the location identifier of the next repeater (F(i+1)) or site (S(i+1)) to at least one location server (SL) in the network, so that it stores said identifier together with the primary identifier of the mobile object (A).

Abstract: A composition including diazoxide (7-chloro-3-methyl-2H-1,2,4-benzothiadiazine-1,1-dioxide) for the treatment and/or prevention of retinal ischemia and of diseases associated with retinal ischemia. The composition can also contain riluzole, a derivative active in neuroprotection of the latter, or a pharmaceutically acceptable salt of the latter.

Abstract: Nucleoside analogues comprising a citrate group can be used to obtain immunogens designed to produce antibodies having an affinity for triphosphorylated nucleosides. Such antibodies are useful for implementing sensitive immunologic assays for triphosphorylated nucleoside derivatives.

Abstract: A recombinant vector containing a cassette for transcription by RNA polymerase III is disclosed. The cassette contains a viral gene transcribed by RNA polymerase III into which an oligonucleotide, a DNA fragment, has been inserted between or outside the boxes A and B constituting the promoter of the viral gene is provided. A method for the intracellular production of an RNA fragment in vitro or in vivo, in which eukaryotic cells containing RNA polymerase III are transfected or infected with a vector according to the invention, containing as oligonucleotides a DNA fragment corresponding to the reverse transcript of the RNA, and in which the eukaryotic cells thus transfected or infected are cultured in a suitable culture medium is also provided. The use of the vectors as a medicinal product is further provided.
