The paper is dedicated to development of modified technology of producing and erection of large fiber-reinforced plastic (FRP) shells. This work gowing with the support of Russian Ministry of science and education. Technology is baced on the method of the vertical wet winding with the growing. The main prospective area of using of this technology, is the reconstruction of the tall chimneys with the erection of inner liner from the FRP shells.

Container gardening is the most promising method in an urban environment where traditional forms of planting in the ground is not possible. For these areas are encouraged to use mobile gardens of tropical and subtropical plants. Offered a basic assortment of plants for the city of Rostov-on-Don. It includes 58 species. For areas with high insolation recommended Yucca aloifolia L., Nerium oleander L., Butia capitata Becc., Phoenix canariensis Chabaud, Opuntia robusta H.Wendl., Euonymus japonica Thunb., Cycas revoluta Thunb., Pelargonium zonale L'Herit ex Ait, Ficus microcarpa L.f., Lantana camara L.

In this article the author examines current challenging aspects of functioning of the supply chains in trading networks, scientific and factographical evaluation of which allows making several conclusions. At present time development of the system of goods circulation in the consumer market will be inevitably accompanied by conservation of a certain level of asymmetry in the distribution of market power and mutual strategic positioning of the parties. On the one hand, such kind of strategic situation is factographically objectified by the author. On the other hand, it preserves the problem of instability of being formed supply chains overcoming of which is possible by means of regulatory intervention of the state. The author defines the dominant position of the state not so much from the point of view of present on today`s market paternalistic beginning as from the position of estimation of potential possibilities of adjustment of goods distribution cooperation and defining it rules.

At the beginning of the 19th century balconies usually arranged in a mansion on the second floor. Most often, they were made of wooden structures with their own vertical supports. In the second half of the 19th century the use of cast-iron and steel struts rail rolling. Balcony plates are in the form of brick svodikov on rails. In tenement houses balconies began to carry out the scheme on the console (embedded in the masonry exterior walls), departure balconies declined.
At the beginning of the 20th century in the construction of a new material - concrete. Supporting structures balconies as steel beams cantilevered embedded in the masonry. Filling the balcony slabs of concrete performed (rubble mixed with concrete, rebar steel rod in the form of a knitted mesh).
In the mid-60 ÷ early 70s. 20th century 5-storey buildings with brick walls were used precast concrete balcony slabs, cantilever embedded in the masonry (250 mm).

In this paper we propose basic geometric, mass and electrical parameters of the element for collection of static electricity from the surface of the textile. This element is a reversible electrochemical charge storage system based on nanostructured nickel oxide and carbon cloth. Element has a planar structure, it is flexible, lightweight, safety and ergonomic. Proposed element can be used as a power source for the Microsystems technique in "smart clothes".

The technological process of aerocrete production consists of many operations during which the considerable amount of dust enters the atmosphere. The results of the dispersion analysis show that the great bulk of the formed dust is made by fine particles to 20 microns. The cyclones used in building industry don't remove the dust effectively. To improve the aerocrete production environmental safety an installation of dust collectors on the oncoming swirl flows is requested.

It describes a method of train set forming for using artificial neural networks to search inauthentic rows in databases tables. An existing methods of the reliability ensure involve the use of integrity constraints and provides a truthfulness, but there is still a possibility of entering of inauthentic data, appropriate to all constraints. A more accurate assessment of reliability is possible with the use of artificial neural networks that require a training set. The main requirement for the training set - representation includes sufficiency, diversity and evenness. The approaches to each of these requirements are describes. Also calculations a sufficient number of rows for training neural networks of various types is given, as well as the results of experiments that confirm correctness of the theoretical calculations.
