Abstract: FIELD: measuring. 
     SUBSTANCE: invention relates to the field of ecology, environmental protection, and pertains to a method for conducting environmental monitoring of the water area of the Björkösund Strait of the Gulf of Finland. The substance of the method consists in taking samples of seawater, bottom sedimentation, phyto- and zooplankton from at least 2 different sites. The collected samples are then analysed, the results of the analysis are compared with the standard indicators of the water area, long-time archival data, and indicators of the adjacent water areas. The muscle tissue of hydrobionts in the form of zebra mussel Dreissena polymorpha, and/or rainbow trout Parasalmo mykiss, and/or Baltic whitefish Coregonus lavaretus is examined for the content of petroleum products. A conclusion is made on the ecological state of the marine ecosystem based on the results of the examination of hydrobionts, sea water, bottom sedimentation, phyto- and zooplankton. If the mass fraction of petroleum products in the muscle tissue samples of the hydrobionts is greater than 150 mg/kg, a conclusion is made that the water area of the Björkösund Strait of the Gulf of Finland could have been contaminated with petroleum and petroleum products. 
     EFFECT: use of the method provides a possibility of conducting environmental monitoring of the water area of the Björkösund Strait of the Gulf of Finland with high accuracy.

Title: Method for situational terminal control of descent module in earth's atmosphere on ricocheting trajectory of return from moon
Inventor: Sikharulidze Yurij Georgievich
IPC: B64G1/12

Abstract: FIELD: aircraft industry. 
     SUBSTANCE: invention relates to the control of the movement of the descent module (DM) in the Earth's atmosphere in the presence of disturbances of both the DM and the environment. The DM enters the atmosphere at a near-parabolic speed from the southern hemisphere along a trajectory with two (I, III) dives into the atmosphere, an extra-atmospheric (II) section, and lands (L) on the territory of the Russian Federation. The descent range (from V1 to P) is 5000...10000 km. This type of trajectory is very sensitive to control and disturbing influences. In the descent control algorithm, adaptation based on autonomous measurements of the apparent acceleration of the DM is carried out with separate identification of the actual aerodynamic quality of the DM and the density of the disturbed atmosphere, as well as the errors of the navigation altitude. This allows choosing the right control in the area of its maximum efficiency - near the rebound point. 
     EFFECT: guaranteed increase in the accuracy (up to 2.7 km) of bringing the DM to the landing point, limiting the duration of action and the maximum value (up to 6g) of the overload, as well as reducing the fuel consumption of the control engines.

Abstract: FIELD: radio engineering. 
     SUBSTANCE: invention relates to the field of radio engineering and can be applied in radio transmitting apparatuses to create power amplifiers with a low level of out-band emissions used in radio communication and television and radio broadcasting. To realise the technical result, the distortion signal is isolated by subtracting the input signal from the output signal, and the functional dependence of these distortions on the input signal is determined. Using this functional dependence in the form of a separate pre-distortion function, a compensating signal is synthesised, admixed to the input of the power amplifier. A look-up table (LUT) can be used as pre-distortion functions. The apparatus comprises a control circuit (3) for mutual alignment of the amplitudes and phases of the input and output signals, an adder (4) for isolating the distortion signal, a unit for calculating the parameters of the pre-distortion function (5), a switch (6), a pre-distortion function unit (7), at the output whereof a compensating signal is synthesised, supplied to the input of the power amplifier (2) after phase alignment (in unit 8), thereby compensating for distortions thereof. For power amplifiers with the memory effect, the parameters of the pre-distortion function are calculated over the entire memory interval. 
     EFFECT: reduction in the level of residual distortion at the output of the power amplifier.
