Change of drivers functional condition while moving along highways of different technical categories

The article analyzes the influence of a human factor on road safety and the main methods of its research. The main indicators of the functional state of the drivers, which most accurately illustrate the change in the neuro-emotional stress while operating the vehicle in different road conditions, are determined. The regularities of changing the functional state of the drivers who were driving the vehicle along different categories of roads were established.

ECOLOGICAL AND GENETIC MONITORING OF THE AGRO - AND BIODIVERSITY OF THE COASTAL ZONE OF WESTERN GEORGIA

The intensity of heavy metals, natural and anthropogenic radionuclides are studied in the cultivated plants and soil in the vicinity of the western coast of Georgia. It is shown that the intensity of their accumulation depends on the type of plant, the place of sampling and the ecological zone. The highest rate of natural radionuclides is 40K, and the lowest - 226Ra, from the technogenic radionuclides the high-quality activeness is characterized to 137Cs, and its accumulation is the highest in the soil. From the hard metals, the plants most actively absorb lead and cadmium.
