Title: Method for surgical correction of congenital asymmetric keeled chest deformation in children
Inventor: RAZUMOVSKIJ ALEKSANDR YUREVICH

Granted: 2021-06-02
Abstract: FIELD: medicine.SUBSTANCE: invention relates to medicine, namely to pediatric surgery, and can be used for surgical correction of congenital asymmetric keeled chest deformation in children. Two incisions of the skin, subcutaneous fat and muscles are performed on both sides along the lateral surfaces of the chest at the level of the greatest deformation. Further, from the cuts on both sides, tunnels are formed between the muscles and ribs in the direction of the sternum. On the side of the deformation, the tunnel ends at the edge of the sternum and on the opposite side at a distance of 2-5 cm from it. Then, in the symmetrical intercostal spaces in the region of the medial ends of the formed tunnels, one hole is made, which penetrates into the chest cavity. Then, from the side of the deformation, a conductor is passed through the formed tunnel and an opening in the intercostal space at the edge of the sternum into the chest cavity. Next, the conductor is removed from the chest cavity through a hole in the intercostal space on the side opposite to the deformation, and is carried out through the tunnel on the side opposite to the deformation. A line is drawn along the conductor, with the help of which a corrective plate, modeled according to the shape of the chest, is installed in the course of the conductor with the curved side forward. Then the plate is turned with the curved side posteriorly, creating a compressive corrective effect on the deformation. Then the ends of the plate are fixed to the adjacent ribs.EFFECT: method ensures reduction of trauma, achievement of reliable intraoperative correction of deformity, stable fixation, cosmetic effect, and also minimizes the risk of damage to the organs of the thoracic cavity by controlling the passage of the corrective plate by forming a tunnel in the tissues of the chest with entry into the chest cavity.1 cl, 5 dwg, 2 ex

Abstract: FIELD: thermal imaging measurements.  
     SUBSTANCE: invention relates to the technique of thermal imaging measurements and is intended for use in metrology for grading, calibration and verification of thermal imaging devices. A method for calibration of thermal imaging devices is claimed, in which the spectral sensitivity of the pixel elements of the receiving matrix of the thermal imaging device is pre-corrected. For this purpose, an optical source of infrared radiation is used, the spectrum of which is as similar as possible to the spectrum of radiation of a black body, and energy brightness is stabilized with a given accuracy, distributed with a given uniformity over an aperture of a given size and shape and is placed in exact correspondence with the thermodynamic temperature of a black body. The spectral sensitivity of pixel elements is adjusted by an amount that is determined based on their brightness and brightness dispersion, the average sample brightness and the average sample brightness dispersion for all pixel elements. As an optical source of infrared radiation, a combination of an optical infrared emitter and an integrating sphere is used, from the output port of which a given spectrum of a given radiation is obtained. This method does not require a long waiting time for the emitter to enter a stationary thermal mode, as is the case in analogues and the prototype. In addition, by providing a high uniformity of brightness across the matrix, the method significantly reduces the likelihood of false signals appearing in the thermal image, which is especially important for thermal imagers used for detection purposes.  
     EFFECT: increase in the accuracy of calibration with the simultaneous reduction in its duration.

First, the biomechanical parameters of the SJ are evaluated: torque in Nm, force in N, the volume of each of the four movements in the SJ in degrees from 0° to 90°, for healthy and injured SJ: flexion, extension, abduction, reduction. Subsequently, a graphical model is constructed for each of the four movements of each SJ in the Microsoft Office Excel program, based on the results of the analysis of which two graphs of dependence are built for each of the four types of movement of each SJ - healthy and injured. On the graphs: 1) on the X-axis, the volume of movements in the SJ is marked in degrees, and on the Y-axis, the force is marked in N, 2) on the X-axis, the volume of movements in the SJ is marked in degrees, and on the Y-axis, the torque is marked in Nm. After that, the two graphs of each of the four movements are superimposed on each other and the minimum points on the Y-axis and the ratio of their values in degrees on the X-axis are determined. Next, these ratios are compared for each of the four movements in the healthy and injured SJ. If the values of the ratios for healthy and injured SJ for each of the analyzed movements are in the range of 1:0.5 and higher, respectively, then the patient is considered to be indicated conservative therapy in the form of exercises using the CON-TREX, PHYSIOMED Elektromedizine AG device, Germany, under the control of the mentioned ratios. If the ratio for at least one of the movements - flexion, extension, abduction, reduction, in a healthy and injured SJ, respectively, is lower than 1:0.5, then surgical treatment is considered indicated.  
     EFFECT: method provides an objective assessment of the functional state of the SJ by biomechanical parameters using the results obtained as criteria for selecting patients for conservative mechanical treatment or for recommending surgical intervention.

Abstract: FIELD: mining industry. 
     SUBSTANCE: invention relates to the mining industry and can be used for the development of complex-structure deposits of the stockwork type, containing ores of various grades and types. The method includes identifying zones with different contents of the useful component, drilling the ore massif, placing explosive charges in wells and blasting them. In the area of ​​contact of rich ores with ordinary ores, double wells are drilled to ensure an increased degree of crushing. Ordinary ore from the contact area is selectively recovered by a front-end loader with a partial grasp of the rich ore, excluding the admixing of the ordinary ore to the main part of the rich ore. The resulting mixed ore mass is impregnated with a concentrated solution of a complexing agent and used for stacking in the lower part of a pile for heap leaching, followed by pouring refractory lean ore onto the mixed ore mass, impregnated with concentrated electrophotoactivated solutions with oxidizing agents that reduce persistence. The main part of the separately mined rich ore is mixed in the form of a slurry with the main part of the run-of-mine ore after separate crushing and grinding for further processing at the concentration plant. Lean non-refractory ore is stacked separately and processed by heap leaching. 
     EFFECT: increasing productivity and technological efficiency, increasing the stability of the quality characteristics of ore supplied for processing, reducing the cost of ore blending in warehouses and increasing the recovery of a useful component during subsequent processing.
