Assessment of the effectiveness of physiotherapeutic methods for management of early menopause disorders

Objective. Assessment of the effectiveness of pelotherapy in combination with phytoaromatic baths in women during menopause transition. Patients and methods. We examined 26 women aged 52 ± 2.4 years. All women with vegetative-vascular manifestations of the climacteric syndrome were randomly assigned to 2 groups for comparison: group 1 – 12 patients, who received full-body “rapa” baths, inhalation phytoaromatherapy with a complex composition including phytoestrogens; group 2 – 14 patients, who received pelotherapy with applications of Saki lake mud on the «panty» zone and hydrodynamic phytoaromatic baths with a complex composition including phytoestrogens. Results. After therapy, a significant improvement of the parameters of climacteric disorders was noted in group 2. Severe disorders were practically absent in the second group – 2% (65 ± 6.1 scores), whereas mild changes prevailed – 64% (18 ± 5.3 scores). Changes in the microcirculation parameter were found, which increased by 19%, an increased contribution of endothelial oscillations to the total flux motion level, an increase of the amplitude of neurogenic and myogenic oscillations, a decrease of respiratory rates on average from 9.2 to 5.51 perf. units. In the first group, no significant changes were recorded. Conclusion. The use of pelotherapy in combination with hydrodynamic phytoaromatic baths permits to improve the parameters of microcirculation, venous and lymph output, trophism and oxygenation of tissues, and also ensures an adaptogenic effect.

Влияние коагуляции капель воды на их распределение по размерам в рабочей части аэрохолодильной установки

Mathematical simulation of coagulation of droplets of finite number of size fractions of a polydisperse mixture, injected by a nozzle into the region of an air-cooler unit along air flux motion direction, was performed. Sets of differential equations describing dependences of droplet fraction concentrations, their densities, as well as masses of droplets in each fraction on time, were solved using the fourth-order Runge–Kutta method. Negligibility of the impact of heat-mass exchange between the substance of droplets and surrounding air on changing their sizes during motion from the nozzle to the operating part of the device is shown. Decomposition of droplets is not simulated, since the critical Weber number is not reached in the considered operating regime of the air-cooler. Results of simulation of droplet coagulation in turbulent air flux show that distributions of droplets by sizes near the surface of a spraying nozzle do not coincide, which proves the necessity of accounting this process in simulation of ice coating of aircrafts in ground conditions.
