An overview of the state and development of ozone therapy technologies in modern biomedical applications, as well as relevant apparatus and equipment, is presented based on reports at the XV International Scientific Conference "Physics and Radioelectronics in Ecology and Medicine - PhREME'2022." Descriptions and technical characteristics of ozone generators used in various applications, from household to clinical use, are given. Data from a comparative analysis of the main parameters of Russian- and foreign-made equipment for ozone therapy, as well as examples of promising innovative developments, are addressed., (© Springer Science+Business Media, LLC, part of Springer Nature 2023, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Underwater light field characterization is of importance for understanding biogeochemical processes and heat budget of the global oceans, which are impacting and reacting to climate change. Vibrational Raman Scattering (VRS) was retrieved from backscattered radiances measured by three different hyperspectral satellite sensors, SCIAMACHY, GOME-2, and OMI, using Differential Optical Absorption Spectroscopy (DOAS). Diffuse attenuation coefficient (Kd) in the blue spectral range (390 to 426 nm) was derived from the VRS signal via a look-up-table established through ocean-atmosphere coupled radiative transfer modeling. We processed one year of data, representative of the overlapping period of optimal operation for all three sensors. Resulting data sets were evaluated by comparison with Kd at 490 nm from Ocean Colour Climate Change Initiative (OC-CCI) which was first converted to Kd at 390 to 426 nm. Good agreement with the OC-CCI Kd product was achieved for all three sensors when Kd was limited to below 0.15 m -1 . Differences among the hyperspectral sensors and to OC-CCI were attributed to particular instrumental effects on the DOAS retrieval leading to temporal and spatial biases. This is in addition to the fact that the spatial and temporal resolution of the hyperspectral sensors data differ among themselves and are much lower then for the OC-CCI Kd-product. Further corrections (e.g., empirical) are necessary before these data sets can be merged in order to obtain a long-term Kd product for the blue spectral range.

The effect of the weak variation magnetic fields on the model biological systems; i.e. the solution of dyes and proteins is investigated. The structural change of these systems under the action of the variation magnetic field of 156.4 Hz and the amplitude of 12.3 A/m was determined by the method of absorbtion and luminescent spectroscopy. It is suggested that this effect realizes through the hypothesis using the method of correlation spectroscopy of scattered light, there have been performed the studies of the structure of water and its changes at different temperatures; on dissolving of non-electrolytes and on exposure to the magnetic field of variable frequency. The accumulated data are indicative of changing the structure of water after the effect of resonance magnetic field. The influence of the weak magnetic fields on the structure of water is due to the clusters which are presented in water and controlled the optical heterogeneity of the medium. The cluster dimensions were evaluated.
