Granted: 2020-11-11
Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to operative urologists. Graft is cut out from the parietal peritoneum and the missing part of the urethra is formed. Endotracheal narcosis is used. Neourethra is formed in a one-stage laparoscopic manner by cutting a free flap from the parietal peritoneum of the required length in the small pelvis, forming the neourethra by suturing the obtained flap on the catheter in the place of the future urethra. 
     EFFECT: method enables reducing a patient's surgical injury by eliminating the need for a repeated operation to transfer the neourethra on the feeding pedicle and forming the neourethra immediately at the site of the portion to be replaced, reducing the risk of complications leading to higher cost of treatment, as well as subjective and objective facilitation of the patient's treatment process.

Abstract: Кавитационный аэратор Волкова предназначен для высокопроизводительной аэрации жидких гомогенных и гетерогенных сред с использовании кавитационного эффекта, существенно ускоряющего как физические тепломассообменные процессы, так и усложненные протеканием химических реакций. Устройство для аэрации жидкости включает корпус с каналом подачи жидкости, каналом подачи воздуха и каналом вывода смеси жидкости и воздуха, причём жидкость подают под давлением в установленную в корпусе полоконусную форсунку с расположенным внутри неё завихрителем с винтовой нарезкой каналов на его внешней поверхности, в зоне выхода конусного факела потока жидкости из отверстия конусной части форсунки установлен отбойник, при ударении о который потока жидкости возникает кавитация, воздух поступает во внутреннюю зону факела потока жидкости по каналу в отбойнике и через отверстие в нём. За счет того что активной средой образования межфазной поверхности является жидкая фаза, площадь соприкосновения фаз существенно увеличивается, процессы переноса определяются не только молекулярной диффузией, но и ускоряются турбулизацией фаз. Он может быть использован для процессов обезжелезивания воды, ускорения процессов очистки сточных вод. 1 ил.

Granted: 2021-12-29
Abstract: FIELD: construction industry.  
     SUBSTANCE: proposal relates to the field of construction and can be used to determine the estimated service life of building materials. On a six-position stand, samples of material in an amount of at least 6 are loaded with at least 5 values of non-critical load at three constant temperatures with time-to-failure fixation. To determine the thermal fluctuation constants of the generalized Zhurkov equation, a reference beam with the coordinates of the pole point (10; -1) was used, i.e. lgτ 0r  = -1, σ mr  = 10 MPa and the maximum temperature of existence of a solid T mr  = 500 K, for which the structural-mechanical constant γ r  is 50 kJ/(mol·MPa), constant U 0r  = 500 kJ/mol. The constant lgτ 0  must be determined from the position of the pole point. The limiting temperature of the existence of a solid T m  is derived from the linear dependence of the tangent of the angle of inclination of the direct temperatures of the graph lgτ - σ, based on the condition that at the limiting temperature of the existence of a solid, the tangent of the angle of inclination of the straight line is zero. The structural-mechanical constant γ should be obtained by multiplying the reference value of the constant by the ratio of the limit temperature of the existence of a solid to the reference limit temperature of the existence of a solid. The constant U 0  should be obtained by multiplying the reference value of the constant U 0r  by the ratio of the limit voltage to the reference limit voltage and by the ratio of the angular coefficient of the linear dependence of the tangent of the angle of inclination of the forward temperatures to the inverse temperature value to the reference value of the angular coefficient.  
     EFFECT: reduction in the labor required to determine the thermal fluctuation constants of the generalized Zhurkov equation while increasing the reliability of their determination (reducing the error in determining the constants).
