    摘要： The present invention relates to a method for the production of chromoplastid carotenoids that can be isolated from fruits. The procedure of the invention allows to selectively isolate, on the basis of the size (Size Exclusion Chromatography) and in pure form, the carotenoid in the form of regularly shaped and sized aggregates. The process includes the following steps: i) production, in suspension, of homogeneous fragments of the chromoplastidial membranes from the fruits; ii) solution isolation of the membrane components by solubilization with detergents; iii) selective and high-purity isolation of the carotenoid in the form of regular paracrystalline aggregates by a screening technique such as size exclusion chromatography (SEC—Size Exclusion Chromatography).

    摘要： A device adapted for a down-hole seismic source, the down-hole being obtained in the subsoil and containing water, the device being adapted for introduction into the down-hole and immersion in water, includes: a cartridge-holding head (22), having a cavity (51) ending into a number of external apertures (24) that constitute firing mouths arranged on the side surface of the head, inclined relative to the longitudinal axis of the head towards the operationally lower end of the head, the end of the head being closed, the cavity being so shaped as to accommodate a cartridge, which can be inserted into the operationally upper end of the head; a cartridge percussion system, inserted into a sealed body (21) and adapted to cause the explosion of the cartridge, and connected to the head in a position operationally on top of the latter, the explosion of the cartridge, which is of the blank-loaded type, causing water to be expelled laterally through the external apertures when the device is operationally immersed in water within the down-hole.
