Abstract: FIELD: radio transmission systems. 
     SUBSTANCE: invention relates to the area of radio direction finding, particularly to determination of bearing of a radio frequency source (RF source) by a system with rotating antennae without strongly pronounced directivity by consecutively changing the position of radiation patterns of the antennas while rotating them in the direction finding plane. To improve the accuracy of direction finding in the proposed method of amplitude-phase direction finding by a rotating antenna system scanning is performed by the radiation pattern of the selected antenna in the direction of the radio frequency source, the maximum signal value at the maximum of the radiation pattern of the selected antenna is determined, equal borders of the ψ i  scanning sector are determined wherein the level of the received signal at both borders within the sector takes equal values and reduces by at least 3 dB from the maximum value, the resulting sector is divided in half, wherein the direction to the radio frequency source is the bearing formed between the direction taken as the starting point and the line dividing the resulting scanning sector in half. The scanning sector is symmetrically reduced to the width of the zone Θ of single-valued interferometric direction finding using an interferometer formed by the selected antenna and the next antenna in the direction of rotation. The rotation angle of the axis of the radiation pattern of the interferometer formed by the antennas is registered, wherein the bearing at said angle is zero within the single-value sector and the angle corresponds with the exact direction to the RF source. 
     EFFECT: improved accuracy of direction finding in a rotating antenna system.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to abdominal surgery. Small intestine segment is resected with perforated tuberculosis ulcers within the limits of healthy tissues at distance of 10 cm in the proximal and distal direction or a right-sided hemicolectomy is performed. Stump of the small intestine is closed with the help of linear stapling apparatuses by two rows of fastening sutures with a height of staples of 3.8 mm and the mesentery is treated with staplers with the staple height of 2.5 mm. Small intestine is intubated to its proximal stump by a naso-intestinal Miller-Abbot probe with active aspiration. Abdominal sanation is performed, 2-4 program sanation relaparotomy is carried out until relief of peritonitis. During program re-laparotomy in the absence of peritonitis phenomena, antiperistaltic delayed intestinal anastomosis is applied "side-to-side" by means of stapling apparatuses, by means of coagulation of a hole in the intestine, below 8 mm-sized staples, the intestines are aligned by the anti-mesenteric edge and the sutures are brought into the aperture. Stapling-cutting apparatus is sutured with intestinal walls. On the formed single stump 5 strands of holders are applied, grasping orifices of an intestine, through which branches are introduced, and a single stump is stitched with a sewing-cutting apparatus, without additional reinforcement by sutures of the anastomosis. Naso-intrinsic probe is inserted behind anastomosis by 20 cm, the abdominal cavity is closed tightly, and after 48-72 hours the probe is removed. 
     EFFECT: method allows arresting and preventing the development of pyoinflammatory complications, to reduce the length of stay of the patients in the clinic, improving the results of treatment in the early postoperative period, reducing lethality.
