The article discusses the practical significance of using the infrared scanning method to optimize the microclimate of wintering grounds for bee colonies in extreme conditions of the cryolithozone. When monitoring the microclimate by generally accepted zoohygienic methods, the devices record specific indicators of a particular parameter (temperature, humidity, air velocity, pressure, noise, light), while the reason for the deviation from the standard indicators for optimizing the microclimate is not always possible to find out. When using the infrared scanning method with the Irtis 2000SN thermal imager to determine the reasons for the deviation of the microclimate parameters from the standards, the following results were obtained: defects of enclosing structures were found: joints of walls and floor and joints of floor boards with a minus temperature of up to -21°C; the entrance group with a defect of heat leakage, warming the outdoor air to -36°C at an outdoor temperature of -48°C; the reason for the deviation of the air velocity of 0.18 m/s deviation from the standard by 0.08 m/s are defects of enclosing structures (Fig.7,8,12). The targeted elimination of the defects of the enclosing structures detected by infrared scanning made it possible to quickly optimize the parameters of the microclimate of the winter garden, thereby increasing the results of successful wintering of bee colonies. The analysis of the wintering results showed that the proportion of successful wintering in 2019 was 90%, which is 20% more than in 2018 and 30% more than in 2017

AbstractThe effect of the angle of dual slots on an air flow field in melt blowing was researched via numerical simulation. Through establishing the geometric model of air flow field in melt blowing with dual slots, meshing, designating the boundary conditions and their parameters and numerical simulation, the result illustrates the influence of the angle of dual slots on the variations of air velocity, pressure and temperature distributions. Higher peak values of air velocity, pressure and temperature are obtained with larger angles of dual slots near the die, while only a few differences of these parameters are detected away from the die. Our results demonstrate the angle of 70° is the appropriate one that can produce the finest fibers.

The aim of the work is to increase the reliability of remote methods of measuring the surface temperature of the human body. Common use of non-contact infrared (IR) devices for temperature screening. But it is important to pay attention to the accuracy of these systems to identify visitors or staff with an infectious disease. The following areas of improvement of metrological characteristics of non-contact devices for measuring human body temperature in a pandemic are identified: 15 cm, the presence in the equipment of a calibrated thermostable source of radiation, called the absolute black body (APT). An effective method of providing the most accurate measurements of skin surface temperature is associated with the use of "baseline sampling". To implement this method, a thermal imager measures the temperature of a specially selected group of perfectly healthy people, with whom the temperature of all others is compared. As a result of the conducted research the requirements to carrying out measurements of body temperature by IR thermometers for reception of reliable results are substantiated and offers on maintenance of these requirements for the purpose of increase of collective safety are put forward. It was found that the lack of calibration when measuring the body temperature of 50 university visitors with an IR thermometer is the cause of gross systematic error, which needs to be corrected by correcting. To increase the reliability of measurements, it is necessary to develop and test a simple and effective method of calibrating IR thermometers, suitable in normal operating conditions. Therefore, it is necessary to calibrate the IR thermometer before the measurements, which eliminates the systematic measurement error. The practical significance of the study is to determine the optimal conditions for the use of the device for non-contact temperature screening in a pandemic. The results of the work will be useful both for further study of increasing the reliability of the results of remote temperature measurement, and may be useful in the learning process.

Clinical Problems

Proper preparative procedures are a prerequisite for the validity of the results of x-ray microanalysis of biological tissue. Clinical applications of x-ray microanalysis are often concerned with diagnostic problems and the results may have profound practical significance for the patient. From this point of view it is especially important that specimen preparation for clinical applications is carried out correctly.Some clinical problems require very little tissue preparation. Hair, nails, and kidney and gallbladder stones may be examined and analyzed after carbon coating. High levels of zinc or copper in hair may be indicative of dermatological or systemic diseases. Nail clippings may be analyzed (as an alternative to the more conventional sweat test) to confirm a diagnosis of cystic fibrosis. X-ray microanalysis in combination with scanning electron microscopy has been shown to be the most reliable method for the identification of the components of kidney or gallbladder stones.A quantitatively very important clinical application of x-ray microanalysis is the identification and quantification of asbestos and other exogenous particles in lung.
