Abstract: FIELD: machine building. 
     SUBSTANCE: invention relates to machine building, namely to active thrust hydro/air-dynamic bearings, and can be used in high-speed, high-load or precession rotary machines. Active thrust hydro/air-dynamic bearing assembly comprises casing accommodating shaft with pivot and liner accommodating one lubricating orifice connected with feed line. In addition, the bearing assembly comprises a control system connected to an axial movement sensor and a shaft speed sensor, as well as a pressure sensor connected to the supply line and control valves connecting the supply line with the lubricating hole. Also disclosed is a method of controlling characteristics of said bearing assembly, which consists in installing shaft with a foot in a thrust bearing, in which there is at least one lubricating hole connected to control valves, wherein axial movement of the shaft relative to the insert is controlled by changing the pressure of the lubricant supplied to the thrust bearing through the lubrication holes by means of control valves. Method then includes setting the setting value in the control system, in which data on pressure of lubricant supply to the thrust bearing, rotation frequency and axial movement of the shaft are additionally transmitted, and at inequality of axial gap and setpoint values change of supply pressure is controlled by program installed in control system, depending on lubricant supply pressure, rotation speed and axial movement of shaft. 
     EFFECT: wider operating range of shaft rotation frequency, control of dynamic and static characteristics of bearing assembly, higher accuracy of control and reliability.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to diving medicine, and can be used for carrying out a renal test with a calcium load in divers. An oral load of 7.5 % calcium lactate solution, depending on the test task, is carried out at one of the lowering stages: before compression, or during compression - pressure increase in pressure chamber, or during decompression - pressure reduction in pressure chamber, in dose of 1 ml of solution per 1 kg of body weight. That is followed by recording the amount of the recovered urine, and the collected urine is used to determine the amount of sodium, potassium, chlorine and calcium released by the kidneys. That is followed by determining a calcium uretic renal function index of the kidneys, CRFI, by formula: CRFI = -5.36 + 0.15 × H 1 −0.31 × K + 0.19 × D + 0.5 × C + 0.19 × H 2  + 0.14 × X, where: H 1  is the amount of sodium secreted by kidneys at 40 minutes after the calcium lactate load, mmol/h; K - amount of released potassium at 60 minutes after loading with calcium lactate, ml/min; D - amount of released urine at 90 minutes after calcium lactate load, ml/min; C is the amount of calcium secreted by kidneys at 90 minutes after calcium lactate load, mmol/h; H 2  is the amount of sodium secreted by kidneys at 120 minutes after the calcium lactate load, mmol/h; X is the amount of chlorine released 120 minutes after calcium lactate load, mmol/h. If its value is less than 0, a calcium uretic renal function is considered unsatisfactory, if the value is from 0 to 1.3 - satisfactory, and more than 1.3 - a calcium uretic renal function is considered to be good for a specific stage of lowering. 
     EFFECT: method provides assessing kidneys of divers in conditions of high pressure of gas medium due to renal test with calcium load in divers at different stages of diving.
