Abstract: FIELD: chemistry. 
     SUBSTANCE: invention relates to a method of determining efficiency of detergents based on probiotics related to a new type of detergents. Proposed method comprises two steps. At the first stage, the exposure time is determined, during which the population contamination of the surface with the test microorganism is reduced by at least 90 %, by treating the test surface contaminated with the test microorganism, a detergent solution based on probiotics. Washings are taken from the surface at definite intervals and crops are sown to solid nutrient media. At the second stage, test-microorganism population is determined by contaminating the test surface daily for at least 14 days with a test microorganism. On the first day, a test microorganism suspension containing 2×10 9  CFU/ml, then daily on the surface is applied a suspension of test microorganism containing 10 6  CFU/ml, after complete drying is treated with detergent solution based on probiotics. After the exposure time defined at the first stage, test-microorganism contamination is determined on test surfaces. Results are compared with data obtained with similarly contaminated control surface treated with sterile water. Based on the results of the comparison, a judgment is made on the effectiveness of the detergent based on probiotics while reducing the population of the test microorganism by at least 99.99 % after 5–7 days from the beginning of the surface treatment. Method is safe and provides validity and accuracy of determination. 
     EFFECT: invention increases efficiency of detergents based on probiotics.

Abstract: FIELD: gas-turbine engine diagnostics.  
     SUBSTANCE: invention relates to the technique of diagnosing the technical condition of aircraft gas turbine engines, taking into account specific operating conditions. The method for operation of an aircraft gas turbine engine according to its technical condition consists in comparing the actual operating time of the engine and the accumulated damage to the main engine parts in static operating modes with their maximum permissible values determined by the results of resource tests on a ground stand, and then determining the remaining resource of the engine and its main parts based on the results of this comparison. The accumulated damage to the main parts of the engine is defined as the sum of the products of the number of typical loading cycles allocated during the flight, determined by the ranges of changes in the cyclic loading of the main parts of the engine, in turn, determined by the characteristic parameters of the engine operation per corresponding single damage. In addition, in dynamic and transient operating modes, the speed of movement of the engine control lever, the physical rotation speeds of the rotors of low-and high-pressure compressors, the gas temperature behind the low-pressure turbine, the engine operating time in each mode and the transition time from one mode to another are measured, after which the accumulated damage to the main engine parts is determined.  
     EFFECT: invention makes it possible to increase the accuracy of calculating the time of damage to engine parts and components during bench life tests.

     SUBSTANCE: invention relates to the field of destruction of durable building materials, namely, to methods of accelerating a projectile in shock-action installations. A method for cocking and accelerating a projectile in the barrel of a shock action installation, including, when cocked, the connection of a hydraulic cylinder, a spring, a projectile and their movement in the barrel, and during acceleration, their sequential separation, characterized in that at first the projectile is in the lower position and rests against the destructible surface, a hydraulic cylinder connected to the barrel pivotally and having a rod with a grip, moves down until it meets the projectile, after which the projectile is captured and moved up the barrel until it stops in the inertial mass, at the same time, when moving, the projectile compresses the spring and, when resting on the inertial mass, the locks installed on it close, forming a single shock mass, when connecting the rod cavity of the hydraulic cylinder with the drain, the grip releases the projectile, which moves downward under the influence of gravity, after covering a certain distance, the locks of the inertial mass open and the projectile, under the action of the released energy of the compressed spring, acquires additional acceleration and strikes the destructible surface, while the inertial mass, moving in the opposite direction, perceives the reactive component of the spring energy and, due to this, does not transmit it to the base machine.  The impact system for the implementation of the method is also disclosed.

Abstract: FIELD: water treatment.  
     SUBSTANCE: invention relates to methods for filtration separation of an aqueous emulsion, in particular to methods for water purification from petrol, oils and oil products, fats (of vegetable and animal origin) and other organic substances. In the proposed method for filtration separation of an aqueous emulsion in a layer of granules using coalescent capture of water-insoluble liquids, a liquid network consisting of a dispersed phase of a separable emulsion or a liquid mutually soluble with a dispersed phase is used as a coalescent catcher. In this case, the liquid network is formed in the gaps between the granules, the entire surface or most of the surface of which is non-wettable for the dispersed phase of the emulsion and the liquid from which the liquid network is formed, and the emulsion passes through the filter layer of the granules through the channels formed by the granules and the liquid network. The solution eliminates clogging of the filter due to contamination of the filter layer granules with heavy fractions of the dispersed phase, since the surface of the granules is (fully or partially) non-wettable for the dispersed phase. The filaments of the liquid network located between the granules reduce the size of the channels and divide the channels into smaller ones, and a decrease in the cross-section of the channels leads to an increase in the speed of the emulsion.  
     EFFECT: invention provides an increase in the reliability and efficiency of the process of filtration separation of an aqueous emulsion in a layer of granules by means of coalescent capture of water-insoluble liquids.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to traumatology and orthopedics, and can be used for bone grafting of ungrown fractures of the inner ankle with the possibility of resynthesis after secondary displacement of fragments and migration of metal structures. The method includes repeated open reposition of fragments with the extraction of the screw fastening them, sawing the autograft from the tuberosity of the tibia. In this case, the autograft is ground along the diameter and length of the extracted screw and immersed in the bed, which is a channel left after the extracted screw. Additional fixation of the ankle to the tibia is carried out with two Kirschner wires carried through the ankle along the edges of the graft. At the same time, the ends of the wires are bent, trimmed off at a distance of 0.5-1.5 cm from the edge of the bone and sunk under the skin.  
     EFFECT: method provides favorable conditions for fracture consolidation due to the high osteogenic potential of the autograft from tibial tuberosity and additional fixation of the ankle to the tibia with Kirschner wire.
