  • Architectural and construction concept of the cable car station in Rostov-on-don

    To the attention of readers is submitted the detailed story about the project of young architects from Novocherkassk " The architectural and construction concept of the cable metro station in Rostov-on-Don". The basic idea of the project - a new decision of a transport problem of the connection of the right and left banks of the river Don - an air cable road. The air metro is ecologically clear, absolutely save (the high resistance to strong winds, and also the high degree of failure in any conditions) and the silent type of passenger transport. Two stations are suggested to Rostovites and guests of the city for comfort using: the multi-level parking and the shopping and entertainment centre on the right and left coasts respectively. This project solves a number of difficult tasks. First of all it combines the functionality and security and at the same time projected buildings completely accord to people's representation about the beauty and the comfort. The creation of the Cable Metro Station allows to solve the transport problem which is typical for big cities, and also it becomes a new sight of our city. Keywords: the transport problem, the cableway, the silent type of passenger transport, multi-level parking, shopping and entertainment centre, the combination of the functionality and security, the constructive scheme - the hard monolithic core, the individualization of the appearance, the unique architectural expressiveness.

  • Investigation of micro-dimensional metal structures obtained by electric explosion of conductors (part 2)

    The article presents the results of experimental studies of the parameters of micro-sized metal particles and sprayed films obtained by the method of electric explosion of metallic conductors (EVP) and electro-explosive spraying (EVN), respectively. Copper (Cu) and aluminum (Al) metal wires were used as explosive conductors. Geometrical parameters and physicochemical analysis of the obtained microparticles and thin films were carried out by means of the universal two-beam electronic system Versa 3D. From the analysis of the obtained samples of sprayed thin films and fine particles, it follows that with a discharge current density J≈10 ^ 10 A / m ^ 2 millisecond, the film thickness and particle sizes can reach values ​​less than micron scale.

  • Environmental assessment of recreational facilities in Rostov-on-Don

    The environmental performance of recreational facilities in Rostov-on-Don was assessed. The object of the study were 15 parks and gardens of the city. Depending on the structure of the territory (the share of the green area, the density of tree planting), the parks were grouped into three groups. The influence of parks and gardens on microclimate parameters was studied - air and surfaces temperatures, air humidity. The greatest reclamation effect on the microclimate is possessed by parks with dense plantations (planting density of trees above 400 pcs / ha). Green spaces have the strongest influence on surfaces temperature, decreasing it by 11.4 - 13.8 ° С. The smallest changes are recorded for air temperature, which decreases on average by 1.9 - 2.3 ° C. Humidity increases by 2.7%. The presence of the effect plantations of trees at parks on microclimate parameters is proved by statistical methods.
