The proposed method applies the ResNet152 layer structure to the encoders in the UNet++ model to detect the location of the TM and affected area with high accuracy. Furthermore, the TM and affected regions can be segmented better than when using the previously proposed UNet and UNet++ models. To the best of our knowledge, this study is the first to use a UNet++-based segmentation model to segment TM areas in endoscopic images of the TM and evaluate its performance. The experiments revealed that ResNet152 UNet++ outperforms conventional methods in terms of segmentation of the TM and affected areas

Methods used in the valuation of assets are usually referred to either a market, or income, or cost approach. Meanwhile, correct valuation methods can be obtained by applying several approaches together. One of these methods is based on the formula proposed by D.S. Lvov at one time, which links the market values of the assessed machine and its analogue and takes into account differences in the operating characteristics of machines and their useful lives. However, when deriving the formula, it is assumed that the characteristics of the machine do not change during the useful life. We propose a generalization of this formula for a situation where the operating characteristics of machines change during their operation, and the useful life is random

This article is about finding an effective solution to the problems of determining the distance and temperature of underground water using ultrasound and radio waves. In the method proposed in the article, we use the highly integrated A9G module, which allows for systematic compensation of the temperature coupling, or easy creation of curves for reconfiguration. The purpose of this scientific research is to increase the distance and accuracy of non-contact measurement of water level in wells. This is achieved by simultaneously creating an ultrasound and a radio wave in the well, which is the starting point for the travel time of the sound wave from the wellhead to the water table, measuring and adjusting the travel time of the sound wave. basic features such as taking into account the ambient temperature are clearly defined. Our proposed method has led to a higher accuracy of groundwater distance determination compared to currently used methods, as other methods measure directly at the water surface and do not take into account the gas temperature in the interval. our proposed method also takes into account the intermediate gas temperature, which increases the reliability. With this dual measurement and gas temperature consideration, we eliminate random measurement and increase accuracy

This article discusses the possibilities of processing and preparing maps for the publication of bathymetric maps, which allows us to significantly change the traditional approaches in the field of preparing maps for publication, laid down in the 70s and 80s of the last century. This provides a new approach to create the basis for the regulatory and technological base of production. To complete the tasks, it is necessary to complete the main stages of work: - to study the main provisions of the guiding documents in the field of hydrography and marine cartography; - to analyze the existing hydrographic data; - to study the basic methods of converting bathymetric data; - to improve technological processes: - convert analog data to digital form; - create a database of bathymetric data for the water area; - generate digital models of the bottom relief for a given water area; - prepare maps for publication using GIS technologies. The article focuses on the technology of creating a database of bathymetric data, as one of the main components in the formation of basic marine geospatial data and mechanisms for constructing bathymetric models of the bottom relief, the development of hypsometric scales of the bottom of water areas, the production of color samples according to the test in the preparation of bathymetric maps for publication.

Frequency, structure and clinical displays Purulent flammatory diseases at 112 children at the age from 0 till 15 years were on treatment in branch of the second Tashkent children’s surgical hospital and addressed for out-patient the help in a polyclinic are studied. Now a number of aspects Pyoinflammatory diseases at children's age requires revision owing to the changed mutual relations between the microbic activator and an organism of the child. Researches testify to change of specific structure of activators Pyoinflammatory diseases in children's age. It is necessary to underline, that absence is connected with plurality of factors of pathogenicity nosologic the specificity, infections caused by is conditional-pathogenic microorganisms that distinguishes them from the majority of pathogenic bacteria. As a rule, standard treatment for most purulent-inflammatory diseases of the musculoskeletal system involves surgical intervention followed by the application of antibacterial and symptomatic therapy. However, correction of immune-metabolic disorders using medications and physiotherapeutic methods is not always employed.The authors also claim that the treatment of this group of patients should be based on a comprehensive approach involving both surgical interventions and therapeutic measures. Surgical methods for treating purulent-inflammatory diseases of the musculoskeletal system dominate and consist of the following main components: primary or secondary surgical treatment of the purulent focus (with removal of the causative tooth of odontogenic origin if applicable) during adequate wound drainage. Special attention is paid to the surgical approach, which should provide the shortest possible route to the purulent focus while also creating adequate conditions for exudate evacuation without forming sinuses and pockets. The therapeutic regimen is divided into general measures, including antibacterial, desensitizing, immunostimulating, detoxifying, and other treatment methods, and local treatment, which involves ensuring adequate drainage of purulent exudate from the focus of inflammation, suppression of the activity of pathogenic microorganisms, maintenance of tissue necrosis, reduction of interstitial pressure, normalization of microcirculation, and acceleration of regeneration processes. It should be noted that currently, most researchers and clinicians adhere to the concept of therapeutic measures that take into account the stages of the purulent-inflammatory process and the pathophysiological processes occurring in the purulent focus.

Children who underwent TEPT had fewer rate of postoperative complications, especially episodes of postoperative HAEC. Therefore, in the treatment of HD in children, preference should be given to TEPT which is less traumatic, had better cosmetic outcome and low incidences of postoperative complications
