Analysis of the theory of the car and its basic elements makes it possible to state the exceptional importance of the pneumatic tire, which provides movement during the operation of the vehicle. The most important parameter that characterizes the condition of the pneumatic tire is the pressure, which can fluctuate during movement, but, at the same time, is a controlled parameter due to the possibility of inflating the tire in the presence of special devices during movement. Methodology. The purpose of the article is a reasonable prospect of creating new models of devices for tire pressure regulation in trucks. To achieve this goal, the methods of hypothesis, mathematical modeling to confirm it, methods of analysis, generalization were used. Results. The article proves that under the influence of the load on the wheel, the air temperature in the tires will be different and, accordingly, there will be differences in the pressure parameters in the pneumatic tires of trucks. In this regard, the solution to the issue of tire pressure regulation in trucks should be considered from the standpoint of differentiated pressure regulation, taking into account the difference in pressure parameters, which allows pumping each individual tire without a forced stop. Originality. The scientific novelty of the article is that it substantiates the promising direction of development of pressure monitoring devices in truck tires based on the analysis of the theoretical model of heating the pneumatic tires. Practical value. The practical significance of the study is that the article identifies the need to change approaches to pressure regulation based on the transition from centralized pumping systems to pumping systems based on a differentiated approach to individual air pressure control systems in truck tires.

Introduction. There are almost no studies characterizing the integrative level of blood pressure (BP) regulation. Materials and methods. 277 people of both genders aged 58.6±6.4 with stage II hypertension disease were randomized into six groups. The monotherapy of hypertension disease was conducted in five groups, using nebivolol, lisinopril, indapamide, amlodipine, and losartan. The sixth group had a combined therapy (lisinopril/indapamide). The therapy effectiveness was assessed at four levels of blood pressure regulation, using the following methods: 1) laser Doppler flowmetry, determination of the level of tumor necrosis factor-α and interleukin-10; 2) echocardiography and Doppler sonography, ultrasound examination of the renal blood flow, ECG, Holter monitoring of ECG; 3) an examination of the heart rate variability level and a quantitative assessment of beta-adrenoreception of erythrocyte cell membranes; 4) the regulatory and adaptive status was assessed, using the method of cardio-respiratory synchronism. Results and discussion. A more significant BP decrease was revealed during a combination therapy (by 20.4% of the baseline daily value). At the integrative level, an index of the regulatory and adaptive status (iRAS) increased in the treatment with lisinopril/indapamide combination (by 40.5%), amlodipine (by 40.5%), losartan (by 35.3%), and lisinopril (by 30.2%). Nebivolol administration resulted in a 13.5% decrease in iRAS. Indapamide therapy had no significant effect on iRAS. Conclusion. A comprehensive assessment of the blood pressure regulation system makes it possible to control the effectiveness of the therapy not only on a target organ or function, but also on the condition of the organism as an integral system.
