H01B 1/12 - Conducteurs ou corps conducteurs caractérisés par les matériaux conducteurs utilisésEmploi de matériaux spécifiés comme conducteurs composés principalement d'autres substances non métalliques substances organiques
The invention relates to an improved miniature device that has been developed for use with liquids at high pressures and at a controlled temperature for the extraction of different types of chemical species from semi-solid or solid samples contained in a closed cell, thereby overcoming certain limitations linked to the thermal inertia of the system. The device includes a resistor that is inserted into a steel tube and a motor which guides air through the tube in order to heat the chamber containing the extraction cells. Both the resistors and the motor can switch on and off independently. The improved device reduces the time required for the liquid-based extraction of different types of chemical species from semi-solid or solid samples, thereby providing a very beneficial advance in terms of solving different problems that exist within the field of sample preparation in analytical chemistry.

POLARISATION CONVERTER AND FOCUSING DEVICE BASED ON SAID CONVERTER
The invention relates to a polarisation converter and to a focusing device based on said converter, of the type comprising an ADTN cell which converts the linear polarisation of an incident light beam that fulfills the Mauguin condition to radial polarisation with two halves that are half-wave phase-displaced along a discontinuity or disclination, associated with a half wave compensator element which acts differently in relation to the two halves of the beam defined by the disclination in order to produce a phase- and radially-polarised beam. The compensator element consists of one or two solid bodies through which the beam can pass, which are applied to one or both halves of the light beam defined by the disclination and which introduce a relative half-wave phase displacement between the electric fields of the two halves in relation to the input thereof.
The invention relates to an achromatic polarisation converter and to a focusing device based on said converter, of the type comprising an ADTN cell which converts the linear polarisation of an incident light beam that fulfills the Mauguin condition to radial polarisation with two halves that are half-wave phase-displaced along a disclination, associated with a half wave compensator element which acts differently in relation to the two halves of the beam defined by the disclination in order to produce a phase- and radially-polarised beam. The compensator element consists of at least one passive liquid crystal cell formed by plane-parallel plates coated with a layer of material that orients the liquid crystal in directions such that, in co-operation with the formation of the liquid crystals, the director is forced to rotate in both halves of the beam, said rotations differing by a half-spiral, thereby preventing the phase displacement of the two halves without the application of external fields.
The present invention relates to the production of transgenic plants with altered levels of starch as a result of the variation of the activity of vegetable nudix that hydrolyse ADP-glucose. Therefore, a description is given in this invention of how to obtain not only transgenic plants that over-express vegetable ASPPs and therefore accumulate little starch, but also transgenic plants that have a high starch content as a result of the reduction of the vegetable ASPP activity.

Abrégé
The invention relates to the biotechnology sector involving the area of human health. More specifically, the invention is based on the surprising usefulness of peptides LxVPc1, c3 and c4 as efficient selective inhibitors of the calcineurin signalling pathway (CN) - NFAT and of the phosphate activity of CN. Said compounds are useful immunosuppressors and serve as a base for the preparation of therapeutic compositions for the prophylactics and treatment of human diseases associated with T-lymphocyte activation, including, but not limited to, autoimmune diseases, inflammation and allergy or transplant rejections. In addition, said peptides and the associated biological and genetic material can form useful tools for the development of tests that can be used to find compounds that have a selective antagonist activity in relation to CN.
