THE EFFICACY OF PROPHYLAXIS OF LYME DISEASE USING ANTIBIOTICS AMONG PEOPLE BITTEN BY IXODID TICKS

For the first time the results of the study of 1399 blood serum, samples from people bitten by Ixodid ticks in Predbaykalye region (East Siberia, Russia) and asking for medical care in the Center for prophylaxis of tick-borne diseases of Scientific Center of Family Health. Problems and. Human Reproduction. SB RAMS. The study showed, high, (up to 99,93 %) efficacy of early antibiotic course in preventing the Lyme disease in bitten peopl

Влияние повышенных температур на работоспособность гидравлического привода

In articles the issue of improvement of quality and efficiency of operability of hydraulically operated cars is investigated at influence of increased temperatures of working liquid and environment. The problem ensuring operability of a hydraulic actuator of the cars operated in wide temperature range, and increase of their efficiency is one of the most actual in domestic mechanical engineeringВ статье исследуется проблема повышения качества и эффективности работоспособности гидрофицированных машин при воздействии повышенных температур рабочей жидкости и окружающей сред

Method for reducing the gas factor in hydraulic fluids

Abstract. This paper considers technologies for reducing the gas factor in hydraulic fluids used in a hydraulic system. Methods and means of reducing the gas factor include three main groups: gas relief, gas separation, and degasification. The work is important because the gas presence adversely affects the operational performance and dynamics of the all system. Finding the most effective way to reduce the gas factor is of primary importance

Effect of undissolved gas on fluid bulk modulus

This document describes the effect of undissolved gas on the bulk modulus of the fluid. The concept of liquid compressibility and dependence on composition, temperature and pressure is considered. Various methods of measuring the modulus of volumetric elasticity of the liquid were considered. It was also proposed to improve the mathematical model for calculating the module of volumetric elasticity of a liquid. The results of the study were used to plot the effect of the gas phase content modulus of volumetric elasticity of working fluid at different pressures. It was also concluded that the obtained values describe the need to equip hydraulic drives with devices for degassing working liquids

Pump jack balancing control method depending on the load

This article focuses on the method of balancing the pump jack and optimizing its operation. In the course of the work, the main balancing methods were considered and a method based on changing the balancing value by moving the movable carriage was proposed. In the course of the work, a model was developed that made it possible to simulate loads, the results of which determined the effectiveness of the proposed balancing method. Based on the results of the study, a graph of the change in torque when the support is located during the operation of the drive was built. Based on the results of the work, the corresponding conclusion was made

Epidemiological Situation on COVID-19 in Irkutsk Region and Forecast for its Spread

Assessment of a particular territory by its epidemiological significance is very relevant in the light of widespread occurrence of new coronavirus infection, COVID-19, in the Russian Federation.Objective. Detection of the epidemiological features and revealing trends in the epidemic process of new coronavirus infection in the Irkutsk Region and forecasting of its spread.Materials and methods. An operational analysis of the epidemiological situation on COVID-19 in the Irkutsk Region as of August 16, 2020 was performed. Restrictive measures were substantiated based on the calculation of the infection spread rate (Rt).Results and discussion. Irkutsk Region remained one of the adverse territories as regards human COVID-19 incidence in the Siberian Federal District and the Russian Federation as of August 16, 2020. The gradual dynamics of the epidemic process was revealed: at the first stage of the epidemic development it was facilitated by the imported cases from affected countries and regions of the Russian Federation, and subsequently by local transmission. The incidence increase was registered 2 months later than in central regions of the Russian Federation. Currently there is a consistent downward trend. The increase in the cases prevailed among rotation workers staying for shift and seasonal activities in the administrative center and northern districts of the Irkutsk Region. The epidemic pattern was determined by gender, age and social characteristics. It is demonstrated that the risk of the new coronavirus infection is determined by the intensity of contacts in family foci, the spread of infection in medical organizations and a significant proportion of asymptomatic carriers. High lethality rates (0.7 %) and mortality rates (31.1 o / oooo) were established among persons over 65 years. The stationary time series observed since June for changing the Rt-indicator with fluctuations ranging from 0.92 to 1.01 requires maintaining control of restrictive measures with prompt management decisions making based on the evolving epidemiological situation in the Irkutsk Region and taking into account the assessment of its possible complication risks
