A developed by authors application for real-time visualization of augmented and virtual reality is considered, which enables to simulate the traffic accidents on a mobile platform with the Android operating system. The application is developed on the basis of the Unity 3D and is able to visualize various types of road accidents and also link them to a terrain, different conditions of the urban environment, and map of the accident statistics. The system has an archive of videos for the accident 3D-scenes. The application interface and implementation features are considered. The subsystems of virtual and augmented reality are described in detail with examples. This application may be used to train novice drivers, learn the rules of the road, and inform experienced drivers about new road junctions. In the system environment, the distribution of the number of traffic violations depending on the driving experience for three groups (no experience, less than 3 years, more than 3 years) was investigated. The study of the usefulness of the system on the Likert scale on 80 cadets of driving schools is presented.

This paper presents microbiological composition of lightbrown soil in the Lower Volga Region, which has been harvest on different nutriculture mediums. Diagnosed characteristics of microbian biocoenosis expansion on drip irrigation and unwatered soils. The Fusarium, Bacillus subtilis and Erwinia, which make more difficult to cultivate and preserve the agricultural produce, had located in irrigated plow horizon of light-brown soil of Volgograd Region. The forms of soil humidity on drip irrigation had not show any influence on microbiological composition.
