Abstract: FIELD: electrical engineering. 
     SUBSTANCE: invention relates to electrical engineering. The method includes converting electrical energy of an energy source by frequency in a transmitting frequency converter and by voltage in a transmitting Tesla transformer, transmitting electrical energy at high frequency along a high-voltage single-wire line to a Tesla receiving transformer, converting electrical energy by voltage in a Tesla receiving transformer and by frequency in a receiving inverter and transmission of electrical energy to the consumer. According to the invention, the transmission of electrical energy is carried out from n remote from each other power sources controlled from the control room at a resonant frequency of fl - 500 kHz and a voltage of 1–1000 kV along n single-wire lines, where n=1, 2, 3..., to one distributed consumer. Controlled electrical energy sources convert energy from renewable energy sources and energy from fossil fuels into electrical energy. The distributed consumer is performed in the form of a three-phase line or microgrid, along which Tesla receiving transformers and inverters controlled from the dispatch center are installed at a distance from each other. Each frequency converter performs the function of control and regulation of frequency, voltage and transmitted power, and each inverter - functions of regulation of maintaining the symmetry of voltage and transmitted power in the phases of a three-phase line. The total length of each single-wire line is related to the resonant frequency by the ratio: fl = nC/2l, where fl is the resonant frequency of oscillations; l - line length; C is the speed of light. 
     EFFECT: reducing the influence of the frequency of energy sources using renewable energy on the frequency and modes of operation of a distributed energy consumer in the form of a backbone line or microgrid.

Abstract: FIELD: medicine, oncology in particular.  
     SUBSTANCE: invention relates to the field of medicine, namely to oncological coloproctology, and can be used to assess the risk of metastatic lesion of the lateral pelvic lymph nodes in patients with rectal cancer. Radiation diagnostics of the pelvic organs and histological examination of the tumor sample are performed. Based on the results of these studies, diagnostic signs are determined, which are measured in points. Distance from the anal margin to the lower edge of the tumor (k1): at a distance of up to 6.0 cm inclusive, 1 point is assigned, more than 6 cm to 12 cm inclusive, 2 points are assigned, more than 12 cm to 18 cm inclusive, 3 points are assigned. The presence or absence of extramural vascular invasion (k2): in the absence of invasion, 0 points are assigned, in the presence of invasion, 1 point. The size of the largest lateral lymph node on the short axis (k3): if the lymph node is not determined, 0 points assigned, if the node size is up to 6 mm inclusive, 1 point, more than 6 mm and up to 10 mm inclusive, 2 points, more than 10 mm and up to 20 mm inclusive, 3 points are assigned, more than 20 mm, 4 points. The depth of germination of the tumor into the intestinal wall (k4): at the depth of germination corresponding to stage T1, 1 point is assigned, stage T2, 2 points, stage T3, 3 points, stage T4, 4 points. Histological structure of the tumor (k5): in the case of highly differentiated adenocarcinoma without mucus formation, 0 points are assigned, moderately differentiated adenocarcinoma without mucus formation, 1 point, low differentiated adenocarcinoma without mucus formation, 2 points, mucin–producing adenocarcinoma, 3 points, in cricoid cell cancer, 4 points. The value of D is calculated by the formula     
     where e is Euler’s number. In the case of the obtained value of D ≥ 0.23, it is concluded that there is a high risk of metastatic lesion of the lateral pelvic lymph nodes. At a value of D<0.23, it is concluded that there is a low risk of metastatic lesion of the lateral pelvic lymph nodes.  
     EFFECT: method provides prediction of metastatic lesion of the lateral pelvic lymph nodes in patients with rectal cancer due to diagnostic signs.

Abstract: An anti-theft system for the protection of a bag of papermoney or the like being transported from a bank safe to a waiting valuables transport vehicle, having a security apparatus for marking or otherwise making useless the papermoney or for giving an alarm in the case of attempted theft. At least one stationary transmitting unit is used for radiating radio waves along the path of transport for being received by a receiving unit on the money bag. The security apparatus is put into operation when the receiving unit no longer receives an agreed information pattern from the transmitting unit, which undergoes comparison with information regenerated at the same data rate from a shift register at the container. In one form of the system, the information to be transmitted and to undergo comparison is produced by the transmitting end and stored sequentially in solid-state memories at a high data rate at the transmitting and receiving ends of the system before each transport operation. Then, on transport, synchronized readout of the information from the memories takes place at a lower data rate for comparison, the security apparatus being put into operation if the transmitted signal is no longer received, this being sensed because of the effect on the comparison operation. In a further form of the system the memories are read only memories which may be exchanged for security purposes.
