A modernized device intended for diagnosing the temperature-dependent activity of cells is described. The activity of cells was determined by finding the correlation coefficient of optical signals in speckle patterns recorded at different moments of time. It is shown that, as the temperature increases from 26 to 36Y°C, variations in the optical paths in cells increase from 16 to 26 nm. This is probably associated with the physiological activity of cells-trapping of large molecules or their conglomerates. In contrast to the pre- vious variant of the device design, instead of a lipid membrane, a cell monolayer was used, which was culti- vated on a plane-parallel glass plate. In order to reduce variations in the optical path lengths in a nutrient solution, a 1.7-mm-thick plane-parallel glass plate was additionally inserted into the cuvette. The modern- ization of the device also includes heating of the cuvette with hot air flows. © Pleiades Publishing, Ltd., 2012.

The work contains the results of calculation and instrumental evaluation of chronic noise exposure. The data were obtained using an approved method of calculating the weighted average daily noise level. The calculation of risk to health of the exposed population in the city is carried out on the base of risk evolution mathematical modeling. The critical age points for the population, characterizing the significant weighting of risk levels at the long-term persistent increased level of urban noise, have been set.

The concept of the triad regulatory metasystem, which includes the neuroendocrine and immune regulation systems, is currently generally accepted. Changes occurring in each of the regulatory systems in response to the impact of technogenic chemical factors are also well known. This paper presents mathematical models of the immune and neuroendocrine system functioning, using the interaction between these systems in response to bacterial invasion as an example, and changes in their performance under exposure to chemical factors, taking into account the stage of functional disorders in a producing organ, using the performance of the bone marrow as an example. © 2014 N.

This paper describes the stages of research of dust emissions from industrial enterprises and the results obtained. An analysis of dust emissions was undertaken to determine their component composition, PM10 and PM2.5 fine particles proportion and morphological characteristics. The data received were considered in a population exposure evaluation. © 2014 WIT Press.
