Laser Technology for Structuring the Surface of Dental Titanium Implants. Part 2 DOI: 10.22184/1993-7296.FRos.2020.14.6.510.519
The first part of this research deals with development of a method for the laser formation of a biocompatible surface morphology of titanium dental implants, providing a hydrophilic surface structure that has both micro- and nanorelief. In this second part of the study, we present the results of preclinical tests of the laser-induced relief’s biocompatibility. The implants with the modified surface showed an advanced proliferation of multipotent mesenchymal stromal cells over the entire surface area, even in open pores. Implants with such a surface also showed positive results of osseointegration in a living organism: three months after implantation, a new mature bone tissue is formed in the previously destroyed bone area, which is directly connected to the implant surface. The technology based on this method has been adopted into the production of a dental milling center for a full production cycle and a plant belonging to the ORTOS group of companies.

System for Recording Interferometer Readings Error Associated with the Temperature Change in Autonomous Laser Meter of Pressure Fluctuations DOI: 10.22184/1993-7296.FRos.2020.14.6.532.537
A system for recording interferometer readings error associated with the temperature change in example stand-alone laser meter of pressure fluctuations is described. The peculiarities of registration and accounting of temperature outside and inside the device are considered, the results of measuring the corrected pressure fluctuations are compared with those theoretically calculated for the frequency range of tides. It is shown that it is strictly necessary to take into account the temperature error, which significantly distorts the primary data.

Optical Ultrastructural Virometry and Its Limitations DOI: 10.22184/1993-7296.FRos.2020.14.6.542.549
The identification of the standard sizes of viral, aggregative and other particles using the virion flow analysis by the light-scattering and fluorescence spectrum requires preliminary calibration of the measuring instrument. Calibration should be carried out according to specific geometric prototypes with specific dimensions. However, the size of viruses varies over a wide range of lengths ranging from nano- to submicrometer sizes. This leads to measurement uncertainty for a wide range of viruses. The software for widely implemented optical instruments is based on a simplified interpretation of the Mie scattering theory, extending it to almost the entire range of particle sizes, even submicrometer ones. The review examines the metrological problems of optical virometry and offers solutions to the issues of instrument calibration.

Issues of Measuring the Moisture Content in the Surface Atmosphere Layer Using an External Emitter and a Photometer with LED Emitters in The Photodetector Mode DOI: 10.22184/1993-7296.FRos.2020.14.6.550.558
The problem of measuring the moisture content in the surface layer of the atmosphere using an external emitter and an LED photometer is defined and solved. It is noted that the absence in many zones of the planet of automated stations for measuring the moisture content of air of the international network AERONET induces the need to develop and use simple sun photometers. The devices for measuring the moisture content in the surface layer of the atmosphere can be built on the basis of two LED light emitters operating in the mode of narrow-spectrum photodetectors. The problem of determining the optimal dependence of external thermal radiation on the wavelength at which the value of atmospheric transmission in the surface atmosphere reaches its maximum is defined and solved. An expression for determining the optimal temperature of the external radiator is obtained.
