Abstract: The present invention relates to a method of detection in vitro of a target substance in a sample. The sample can comprise, among other things, a nucleic sequence or more generally any type of substance. In particular, the present invention provides a method of detection comprising (i) specifically labeling a substance with a reporter gene and any sequences necessary for the in vitro expression of the reporter gene; (ii) in vitro transcription and translation of the reporter gene; and (iii) in vitro detection of a reporter protein coded by the reporter gene.

Abstract: The invention relates to programs enhanced by applications. It relates, furthermore, to the associated production and broadcasting systems, in particular to interactive digital television. The activation of an interactive application associated with a broadcast program may be done manually in the broadcasting channel. This solution is expensive, lacks accuracy, and the control of the application is managed not by the production channel but the broadcasting channel. The invention therefore proposes to use a broadcasting program signal comprising primary data for the reproduction of the passive main content of the program and secondary data watermarked in the primary data. These secondary data comprise the commands for triggering at least one application such as, in particular, the controlling of one or more broadcasting parameters of said program signal and/or of one or more applications, for example interactive or broadcasting, related to said program signal.

Abstract: The invention concerns a method for determining the activity of a substance using a functional test, characterized in that it consists in detecting and/or measuring the variation of a known function corresponding to one or several proteins produced in vitro in the presence and in the absence of said substances or to the substance in the presence or in the absence of one or several proteins produces in vitro.

Abstract: Method of gene shuffling using hybridization of fragments on assembly templates, wherein the fragments are not themselves the templates. Invention is particularly aimed at generating novel polynucleotides that differ in some advantageous respect compared to a reference sequence. Invention further includes reaction mixtures created by or during the method, sequences created by the method, hosts and vectors containing same, and proteins translated therefrom.

Abstract: The present invention relates to a process for separating technetium from a nitric solution of technetium through cathodic electrodeposition of said technetium by electrolysis. According to the process of the invention, the nitric solution of technetium is denitrified and its pH is adjusted to a value of approximately 5.5 to 7.5 before electrolysis. Electrolysis is conducted at galvanostatic rate, and the cathode potential is approximately −1.36 V/SHE to −1.16/SHE. The ratio of the cathode surface area (S) to the volume of the technetium solution to be electrolyzed may be in the region of 0.25 to 0.50 cm−1.

Abstract: A X-MAC encoder enables a plurality of components to be encoded, each having a sequence of packets, with the packets being distributed in successive bursts each occupying a predetermined fraction of a television frame line. It comprises a plurality of blocks each having at least one packet encoder provided with a buffer memory for storing digital data coming from a source, and an encoder for distributing the packets in bursts of adjustable duration not greater than the duration of one television line. A base encoder assembly contains a programmable device for allocating a determined window of the television frame to each block. It calls a burst of length corresponding to the width within the window that is allocated by the programmable device, on the basis of the respective block burst encoder, at the beginning of each window in a line.
