Abstract: The present invention deals with a Multigrid High Pressure Gas Proportional Scintillation Counter for the detection of ionizing radiation such as X-rays, gamma-rays, electrons or other charged leptons, alpha-particles or other charged particles as well as neutrons, which gives information about the energy dissipated in the gas and the time of occurrence of the detection, through an electronic pulse with an amplitude approximately proportional to that energy.

Abstract: A punch, apparatus and method for forming opposing holes in a hollow part, and a part formed therefrom. The punch includes an end portion adapted to pierce an entry hole and bend material around the entry hole to form a retained slug along an inner edge of the entry hole. The punch also includes an enlarging portion adapted to enter the entry hole after the end portion to enlarge the entry hole by bending the slug and additional material towards the interior? of the part. The punch has a length greater than a cross-section of the part such that further advancement of the punch through the part punches an exit hole in the part opposite the entry hole.

Abstract: The procedure concerns placing into contact a lycopene source with a supercritical fluid under conditions that permit the solubilisation of lycopene in this supercritical fluid and to separate the lycopene concentrate by depressurisation of the supercritical fluid loaded with lycopene. When the depressurisation is carried out at pressures below 10 MPa, an oleoresin is obtained and when it is performed at pressures above this an extract is obtained, both of which are rich in lycopene free of organic solvents. The concentrate and the compositions it comprises have antioxidant properties and are useful for elaborating food products, cosmetics and pharmaceutical and nutraceutical products.
