Abstract: Method of manufacturing zirconium alloy tubular products containing (wt. %): niobium—0.9-1.7; iron—0.04-0.10; oxygen—0.03-0.10; silicon—less than 0.02, carbon—less than 0.02, and zirconium—as the base of the alloy. This includes an ingot melting by multiple vacuum arc remelting, mechanical processing of the ingot, heating, hot working of the ingot, subsequent mechanical processing for the production of tubular billets, heat treatment of the tubular billets, application of a protective coating and heating to a hot pressing temperature, hot pressing, removal of the protective coating, multi-stage cold radial forging, vacuum thermal treatment, multiple cold rolling runs with a total deformation degree of 50-80-% per run and a tubular coefficient of Q=1.0-2.7 with intermediate vacuum thermal treatment after each cold rolling operation, and final vacuum thermal treatment of the resulting tubular products carried out at the final size with subsequent final finishing operations.

Abstract: The method for processing heavy hydrocarbon feedstock, predominantly heavy crude oil, comprises pre-treatment of an initial feedstock and an auxiliary gaseous mixture at a pre-set pressure, introducing the pre-treated auxiliary gaseous mixture into the pre-treated feedstock and mixing thereof, cavitation treatment of the resulting mixture, separating liquid and gaseous products followed by isolating the final petroleum product. The novelty is in that gaseous hydrocarbons having the activation energy comparable with the molecule dissociation energy of the main components of the heavy hydrocarbon feedstock, are used as auxiliary gaseous mixture; and the pre-treatment of the initial heavy hydrocarbon feedstock and the auxiliary gaseous mixture, both of which are in the liquid state, is performed at a pressure which exceeds the saturated vapour pressure of the auxiliary gaseous mixture.

Abstract: The invention relates to gas separation, in particular to separation of CO2 from CO2-rich liquids, particularly from CO2 absorption liquids used in the removal of CO2 from off-gases or product flows, such as natural gas or synthesis gas. According to the invention, CO2 is separated from a CO2-rich liquid by a method comprising a step wherein, under elevated pressure, said liquid is contacted with a membrane based on polyacetylene substituted with trimethylsilyl groups such that the pressure across the membrane is at least 1 bar and that at least a part of the CO2 is transported from the liquid through the membrane.

Abstract: This invention relates to biology, veterinary and medicine, and more particularly to methods and devices for physiotherapy with the use of electromagnetic radiation in the ultra-high frequency band. The method consists in that patients are irradiated with electromagnetic microwave field at, at least, one frequency belonging to, at least, one of the 18 frequency ranges. The intensity of radiation at the place of location of the patient does not exceed 3.6 ?W/cm2. The device for carrying out the method comprises, at least, one oscillator ensuring the production of electromagnetic radiation in the 18 frequency ranges, both at the main frequencies and at multiple ones. In the result the effect of pain relief is achieved, inflammatory processes are lessened, processes of regeneration of damaged tissues are stimulated, an affected immune status is corrected, the processes of cell proliferation in neoplasms are stabilized, the lysis of necrotic tissue cells occurs.
