Create a new underground storage and expansion and optimization of existing underground gas reservoirs is one of the priority directions for the development of the gas industry. The aim of the work is to determine the methodology of leakage and losses of underground gas reservoirs. There is a presented an analysis of the hysteresis loop of the underground gas reservoir compaction-removal cycle and the corresponding leakage.</p> 2024-05-15T00:00:00+00:00 Copyright (c) 2024 Lena Shatakishvili, Ketevan Berikashvili https://rsglobal.pl/index.php/ws/article/view/2791 THE METHODS OF THE SORBED QUANTITY OF THE DIFFUSION COEFFICIENTS AND POLYMERS LIQUID AREAS 2024-05-26T17:24:39+00:00 A.D. Porchkhidze info@rsglobal.pl <p>Has been discussed diffusion coefficients, the amount of the liquid particles sorbed by quantity, as well as the methods of determining molecular masses of polymers. We were researching liquid area’s kinetics of vapor sorption on the MCBean scale. We’ll also determine the molecular masses of polymers by the viscozimetric method.</p> 2024-05-16T00:00:00+00:00 Copyright (c) 2024 A.D.

Numerical study of fuel spraying characteristics by diesel injectors at injection pressures in the range from 50 to 300 MPa has been conducted.<br>Based on the analysis of the known designs of thermally insulated combustion chambers, the technology of manufacturing a pilot piston is proposed, which is based on the application of a ceramic coating using zirconium dioxide powder on the walls of the combustion chamber of the mass-production piston.</p> 2024-06-23T00:00:00+00:00 Copyright (c) 2024 Giorgi Purtskhvanidze, Mikheil Lejava, Zaza Shubladze, Jemal Sharadze, Irakli Khajomia https://rsglobal.pl/index.php/ws/article/view/2750 COMBINATION OF HYPERTENSION AND DIABETES MELLITUS IN THE PRACTICE OF A FAMILY DOCTOR 2024-06-29T16:44:27+00:00 Вовк К.В. vovkkira1970@gmail.com Шерстюк Л.Л. info@rsglobal.pl Власенко О.О. info@rsglobal.pl Шумова Н.В. info@rsglobal.pl Резніченко О.Г. info@rsglobal.pl Кратенко Г.С. info@rsglobal.pl <p>The relationship between arterial hypertension (AH) and type 2 diabetes mellitus (T2DM) has long been established based on the results of large-scale epidemiological and population-based studies. The number of patients with hypertension in combination with type 2 diabetes mellitus has been steadily increasing in recent years, increasing the risk of developing both macro- and microvascular complications, which progressively worsens their prognosis. LDL cholesterol is also a prognostic indicator of stroke risk in type 2 diabetes with a combination of several risk factors (hypertension and dyslipidemia), and early detection and early prescription of lipid-lowering therapy for the treatment or prevention of cardiovascular disease is especially important. In the presented clinical case in the patient on the background of rosuvastatin and fenofibrate administration there was a significant positive change in triglycerides from 3.8 mmol/l to 1.34 mmol/l. The problem of treatment effectiveness and improving the prognosis of patients with diabetes and hypertension remains complex. Success in treatment depends on compliance with the following provisions: the effectiveness of the antihypertensive properties of drugs (antihypertensive, hypoglycemic, hypolipidemic), the ability to achieve the target level of office blood pressure, SBP, since patients with diabetes mellitus with hypertension are mostly non-dippers; achieving and maintaining high adherence to therapy for many years.</p> 2024-06-16T00:00:00+00:00 Copyright (c) 2024 Вовк К.В., Шерстюк Л.Л., Власенко О.О., Шумова Н.В., Резніченко О.Г., Кратенко Г.С.
