Abstract: Process for the impregnation of a polymer substrate including at least one polymer, which comprises putting said polymer substrate in contact with at least one aqueous emulsion, preferably an aqueous microemulsion, including at least one organic additive. The impregnated polymer substrate obtained from said process can be advantageously used for obtaining polymer end-products having improved aesthetic characteristics (for example, impregnation with at least one dye) or stability characteristics (for example, impregnation with at least one stabilizer), which can be used in various fields such as, for example, the optical field (e.g., advanced optical components, laser applications), the medical field (e.g., the release of pharmaceutical substances), the agricultural field (e.g., release of pesticides), fragrances (e.g., release of fragrances).
Abstract: A method and a system remotely detect the position of a pig device inside a pipeline for transporting pressurized fluids, like for example long distance oil and gas pipelines having a strategic international value. The method foresees equipping the pipeline with pressure sensors in contact with the fluid, located at at least one of the two terminals of the pipeline, and the sending and processing of signals by a control unit. The operation of the system is that of identifying and locating, in real time and continuously, a pig device that moves intermittently inside the pipeline, for example during cleaning, monitoring, measurement and non-destructive control operations.

Abstract: The present invention concerns an oleaginous yeast variant of the species Rhodosporidium azoricum characterized by higher biomass yields and intra- cellular lipid accumulation useful for the production of bio-fuels higher, in determined conditions, with respect to the wild type strain of the same species. Furthermore, the invention concerns a method through which said oleaginous yeast variant of the species Rhodosporidium azoricum was obtained. The invention further concerns the lipid production by means of said variant strain of oleaginous yeast of the species Rhodosporidium azoricum.
Abstract: Method for maximizing the reaction volume in a slurry phase reactor by determining the ratio (f) between the height of the foams (Hf) and the height of the reactor (HR) through an algorithm defining the gas hold-up in three zones, a first lower zone in which a bubble regime is established, a second intermediate zone where there can be the presence of foams, a third zone situated in the upper hemispherical part in which the multiphase mixture is accelerated until it reaches outlet conditions, the average gas hold-up being given by the weighted average of each of the three gas hold-ups of the three zones, characterized in that it uses nuclear densimeters positioned inside the reactor at different heights and comprises: measuring, for each nuclear densimeter used, gas density values, relating to different gas and/or slurry velocities, which correspond through said algorithm to calculated gas hold-up values, revealing, with a calculated gas hold-up of less than 40%, the absence of foams at least up to the height

Abstract: A safety valve assembly for extradition of hydrocarbons includes a valve body including a passage duct, configured to be traversed by a production and/or drilling line. The valve body includes housings for a punch and counter-punch, arranged diametrically opposite to one another with a common longitudinal axis substantially perpendicular to the longitudinal axis of the valve. The punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe, and the counter-punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe. The punch and counter-punch are configured to allow the counter-punch to slidingly receive the punch in its interior to create two different shearing planes. The counter-punch includes a hollow part to slidingly receive the section of tubular material and the punch, in the linear movement during the shearing operation.
