Introduction. Methods of automatic measurement of rail track joint gaps are not accurate enough or require costly equipment and sensors. This is why joint gaps are still monitored manually in many cases. The work is intended to experiment and examine a new method of automatic measurement of gaps in bolted rail joints using magnetic flaw detection (MFL).Materials and methods. The paper uses actual track inspection results obtained by a flaw detection car on one of the railroads of Russian Railways. A specially developed programme used magnetic channel signals to highlight bolted rail joint locations and determine the magnitude of the joint gaps. The joint gaps were also measured manually using video images of bolted joints obtained by the on-board rail video recording system.Results. The authors obtained expressions for calculating the joint gap value using magnetic sensor signals. Small gaps (up to 8 mm) are estimated by amplitude, medium and large gaps (above 9 mm) — by the spatial parameter of the signals from joint gaps. The authors compared the gap measurements from the two specified methods: visual and magnetic.Discussion and conclusion. The research confirmed that automatic identification of bolted joints and determination of the value of joint gaps by magnetic rail flaw detection are sufficiently reliable for practical application. A comparative analysis of the values of the video inspection and the magnetic method showed high accuracy of joint gap measurement when using the latter. The magnetic method signals show high stability and repeatability.

The objective: to compare the effectiveness of endoscopic diagnosis of bronchial tuberculosis in pulmonary tuberculosis patients with different HIV status.Subjects and Methods. The data obtained during tracheobronchoscopy in 371 respiratory tuberculosis patients from 2018 to 2020 were retrospectively studied. The indication for bronchoscopy was the presence of clinical and radiological symptoms characteristic of bronchial tuberculosis in a pulmonary tuberculosis patient. All patients were divided into two groups: HIV+ and HIV-.Results. In pulmonary tuberculosis patients with clinical and radiographic findings characteristic of bronchial tuberculosis, the frequency of endoscopic confirmation of bronchial tuberculosis in HIV+ Group was 57/71 (80.3%), in HIV- Group – 138/300 (46.0%), p < 0.01; χ2 = 27.06.Most often, in HIV-positive patients, the infiltrative form of bronchus tuberculosis was detected – 27 (47.4%) patients, and the fistulous form – 23 (40.4%) patients, bronchial lesions in HIV negative tuberculosis patients were mainly infiltrative – 94 (68.1%) or ulcerative – 24 (17.4%).The frequency of microbiological detection of the causative agent of tuberculosis increased when bronchobiopsy was performed versus sputum microscopy, especially in HIV negative tuberculosis patients (from 39.9 to 91.3%), and among HIV positive patients from 15.7 to 47.4%.

The article deals with one of the components of the advertising text as a sign of regional linguoculture. Legal and ethical aspects of the description of advertising models typical ofKemerovoenvironment are based on the main principles of communicative and cognitive linguistics. The article offers a system of directions that can be used to describe the ethical structure of the advertising text and states a method that can be applied to advertising models analysis. The study was conducted on the regional linguistic material that allowed us to structure the system of advertising names and texts ofKemerovoas objects of transformational cultural linguistics, a special branch of contemporary ethnolinguistics engaged in the study of language change in the norms of city-space communication and in the language consciousness of kemerovites. The article introduces the notion of ethical representations of advertising consciousness.
