Microorganisms are used for the prevention, treatment of infectious diseases of plants and increasing yields. Products based on a culture of microorganisms mankind use as an alternative to chemical pesticides and fungicides. In this work we consider Streptomyces as agents of biocontrol and plant growth stimulator as well as induced by their mechanisms, metabolic pathways. We experimentally proved antifungal, the antibacterial activity of Streptomyces isolates obtained from compost.

Processes of self-assembly were studied in the magnetic polymer carbon nanocomposites doped with cobalt nanoclusters. These processes proceed due to the diffusion of magnetic nanoparticles stimulated by a combined effect of an outer steady magnetic fields and heating. The obtained polymer composites are promising for practical applications.

Cyber-physical  systems  as  dispersed  systems  based  on  interacting  networks  of  physical  and  computing components provide new functionalities for improving the quality of measurement processes. It is proposed to carry out automated operational setup of metrological parameters of these systems measuring channels during operation basing on the code-controlled measures-imitators.

The mathematical model of stress-strain state aboveground station of pipeline is investigated with taking into consideration interaction aboveground part of pipeline with adjacent to it parts of under­ground pipeline. The underground parts of pipeline which leaning on the soil are considered as elastic Winkler type basis. Local we­akening station of pipe­line in connections areas under­ground part of pipe­line with aboveground part are simu­lated by the in­troduction elastic joints into a system.

Effect of mechanical relaxations on the relaxation phenomena of electrical conducting polymer composites (ECPC) has been investigated. It has been experimentally shown that filler content significantly affects relaxation characteristics of the material. The main reason of these differences is the effect of the filler type on proceeding of relaxation processes. Rubbers with active carbon blacks display the ranges of slow and fast relaxations much more clearly than those with low active carbon black.
