Free living Nematodes communities used as bioindicators of soil health because their composition well correlates with, two critical ecological processes i.e. nitrogen cycling and decomposition in soil . Nematodes indices withstand statistical rigor better than abundances, proportions, or ratios of trophic groups. Nematodes indices respond to a variety of land-management practices, based largely on life history characteristics of families.

According to agrotechnical requirements, the technological process of potato harvesting should be carried out in a short period, with minimal losses of the grown yield and preservation of its quality. The fulfillment of these requirements depends on the organization of harvesting operations, the qualifications of employees, the technologies involved, the technical aids used, as well as natural and climatic conditions. Based on this, the authors propose to consider the potato harvesting process as the functioning system "man-machine-environment-transport", the main evaluation indicator of which

The stable and efficient operation of Electromechanical Energy Converters (EECs) is largely determined by the early detection and prevention of developing defects. Early defect detection can be performed by monitoring changes in the behavior of the characteristic indicators/criteria of the EEC. Considering that EECs have a complex design and, in some cases, operate in non-standard modes and environments, a statistical analysis of changes in the most common indicators subject to monitoring is proposed.
