It is important for any enterprise engaged in the production of products to have a sufficient number of freight vehicles at the enterprise for timely delivery of manufactured products to places of sale, as well as its efficient use. In order to analyze objectively the dynamics of availability, work results and evaluate the efficiency of using freight vehicles, a system of initial and absolute performance indicators was formed, characterizing the actual availability of vehicles, as well as the days of their stay at the enterprise; number of days spent waiting for repairs and undergoing repairs; actual number of days in work; total load capacity; time on duty; time spent in motion; volume of goods transported; technically possible scope of work (volume of cargo turnover); volume of work actually performed (volume of cargo turnover) and a number of others; the source of information was indicated and an algorithm for calculating indicators was given. Therefore, the following methods for calculating the main economic indicators will allow future specialists to familiarize themselves with methodological aspects of analyzing the activities of freight vehicles using a specific example.

Technogenic and natural nanomaterials are alien to living systems. The negative effect of nanomaterials may be due to their accumulation in intracellular organelles. The properties of nanoparticles are determined not only by their size, which manifests itself in the activation of a thermodynamic variable, but also by their chemical structure and shape, their ability to aggregate. The effect of metal nanoparticles and oxides of cobalt and titanium on the development and growth of plants has been studied. An important established fact is the ability of oxide nanoparticles, unlike metals themselves, to accumulate in living systems. Transmission electron microscopy, carried out by means of electron microscopic analysis, has revealed interstitial bioaccumulation of nanoparticles of cobalt oxide and titanium oxide in the form of aggregates 80-300 nm in size. If nanoparticles quickly aggregate, they are less dangerous for organisms than single nanoparticles, since a large aggregate of nanoparticles cannot get inside the cell. The rate and dynamics of deposition of nanoparticles of metals and their oxides in water are different. Metal NPs are deposited much more slowly than titanium dioxide. Moreover, the safety of NPs depends on their size and concentration. Biogenic nanoparticles with a size of 35-75 nm have high biological activity, biocompatibility and environmental safety. There is a direct correlation between the energy produced in cells, which is necessary for seed viability, and an increase in the number of protons under the action of metal nanoparticles, which leads to an increase in the permeability of cell membranes and the activity of enzymes and phytohormones.
